What About the Laptop Keyboard

Early this morning, the happy rabbit, who always smiles, came to work with a sad face. It turned out that his ibuddie keyboard suddenly broke down, several keys couldn't be used, but there was no response. There were no characters on the screen. Due to the problem that happened last night, his plan to chat with MM came to naught. He started the computer to demonstrate to the stone, in which the 1, 5, 6, -, , del and tab keys could not be used. These keys are distributed in a wide range, and I really can't guess why for a moment. Finally, the rabbit thought of Luo Gong. In order not to delay his work, he immediately got up to pack up, but he had to pull a stone to carry his bag. Who makes me strong? I can't help it. Stone will go with him. Seeing Luo Gong explain the situation, he took down the keyboard without saying a word, looked at it, and said decisively, "there is water in your keyboard, so you can only replace it." the stone and the rabbit looked carefully, and the underside of the keyboard was really dirty, full of stains like coffee or tea.

Luo Gong lifted the rubber cap and exposed the key contacts below. It's even more ugly inside. The contacts are full of brown dirt. Luo Gong said that if such a problem cannot be repaired at all, it can only be replaced with a new keyboard. Stone felt a little strange when Luo Gong said so. Because the stone has also encountered water in the keyboard before. Although it is the same fault, it can be used normally after cleaning. It is not necessary to replace it. Luo Gong listened to stone's question and asked Stone, "is that keyboard for notebook or desktop?" "desktop" Stone said. "The keyboard of the desktop computer is different from that of the notebook. Look at this," said Luo Gong. He opened another button and saw a rubber cap under the plastic cover.

(Fig. 3) Luo Gong said that different from the ordinary desktop keyboard, the contact of this ultra-thin keyboard is very small and coated with conductive adhesive. Every time a key is pressed and a contact is touched, an electrical pulse can be triggered. If there is liquid infiltration, the conductive adhesive will dissolve and lose the conductive function, and the pulse will not be triggered, so the function will be lost. The contact point of desktop keyboard is not as small as that of notebook, and the structure is also different. If there are stains infiltrating into it, it can be used normally as long as it is wiped clean with volatile liquid such as alcohol.

After listening to Luo Gong's explanation, stone suddenly realized. However, it is strange that if the keyboard is flooded, it should be concentrated in a relatively small range, but the damaged keys are large from left to right. Why? As soon as the rabbit patted on the forehead, he suddenly remembered and said that there was a humidifier in his room, right next to his computer. Maybe the moisture had seeped in. Stone was a little embarrassed to hear him say so. The reason why electronic products can't be affected by moisture is the simplest. However, the rabbit didn't notice it. He was so careless that he really convinced him. Luo Gong pointed to the rabbit ibuddie keyboard and added, "if you look at the stains carefully and measure these parts with a multimeter, you will find that they are no longer conductive, so this keyboard cannot be repaired. It is scrapped and can only be replaced. According to the regulations of our maintenance department, you need to pay a fee. In the face of your website XJ adults, you can give a discount, as long as The rabbit almost fainted when he heard that he would lose so much money if he accidentally entered some water. It's a disaster. But I can only blame myself for being careless. I can't blame others. Just when the rabbit shouted bad luck, Luo Gong had replaced the new keyboard. The stone saw the replaced waste keyboard and found that there were stains on the back.

(Figure 4) no wonder the keyboard doesn't work. If the liquid seeps into the internal circuit board, the consequences are even more unimaginable. Luo Gong said that at present, the notebook keyboard produced basically has no waterproof function, so users must use it carefully. Stone here should also remind the majority of users that they must take good care of products such as notebooks and ibuddie. Don't say sprinkle water on the keyboard. You can't get it even in rainy days, and don't use it in a humid environment. The careless rabbit taught us a lesson today. We must use it carefully in the future.

What If the Laptop Keyboard Fails
What If the Laptop Keyboard Fails
Computer keyboard is one of the most commonly used computer input devices, and it is also the most frequently used device. Due to the high frequency of use of computer keyboard, the failure of computer keyboard often occurs in the process of use. Today, I'll share with you the solutions after the computer keyboard fails.There are generally two cases of laptop keyboard failure:One is to press the letter key to turn it into a number. Many friends who know about notebook computers will know that the number keys and letter keys of notebook keypad are integrated. Generally, pressing fnnumlk key can intelligently switch to the number keypad. Some notebook brands may be different. You can refer to your own notebook operation manual.In another case, there is no response to pressing, or the key is not displayed regularly. Most of these are keyboard problems. You can try to clean the notebook keyboard and check each key to see if some keys don't pop up when pressed, resulting in the useless pressing of other keys. In addition, if the notebook keyboard is damaged, you can replace it (but the cost is very expensive), or it's good to buy an external interface keyboard, It's cheap.If none of the above methods can solve your problem, try the following solutions:1. Modify the driver of notebook keyboard.Open the system properties through "my computer", select the hardware tab, and open the device manager. We found that under the Chinese Windows XP operating system, the default keyboard driver is "standard 101 / 102 key or Microsoft natural PS / 2 keyboard". Right click to select update driver, and the hardware update wizard will appear: select "install from list or specified location (Advanced)", click "next", and select "do not search. I want to select the driver to install myself." click "next" to enter the "select device driver to install for this hardware" page, and remove the check box "display compatible hardware" Small hook in front of the.

Modify the registry.Click "start" menu, click "run", enter "regedit", open the registry and enter "hkey_local_machinesystemcontrolset001controlkeyboardlayouts", which has many subitems. Through observation, I found that the input methods ending with "0804" are simplified Chinese input methods. Open "e00e0804" and you can see that there is a sub item "layoutfile" in the sub item on the right. Double click to open the item, change "kbdus. DLL" in "numerical data" to "kbdjpn. DLL" and click OK. By analogy, you can change "layoutfile" in all sub items ending in "0804" to "kbdjpn. DLL", which is selected according to your common input method. Then restart the computer!There are many reasons for laptop keyboard failure. The more common ones are the two introduced to you at the beginning.

It makes our work and study more efficient, so it can be widely praised by everyone. However, once we encounter the scene of forgetting the keyboard lock, it will inevitably bring many inconveniences to our life. Therefore, it is very necessary to master some relevant knowledge. Then you might as well learn a few words and pictures about the setting method of laptop keyboard lock and unlocking method with Xiaobian.1 How to unlock the laptop keyboard lockMethod for unlocking keyboard lock of notebook computerWhen starting up, you can directly press F10, and then enter a BIOS page, where you can set the password for the keyboard. Of course, you can set the password and unlock the password. However, it should be noted that different models of laptops have different ways to enter BIOS mode, some with F8 key and some with del key. In this way, you can observe whether the NumLock key of building materials is on. If it is not on, you can turn it on. You can also select the run button in the start menu to enter the run dialog box, enter the regdit command to enter the registry, and then press the following value to change it Defaultcontrolpanelkeyboard] "initialkeyboardindicators" = "2" enter it.Unlocking method 2 of laptop keyboard lockAfter restarting the laptop, observe whether the three LED lights on the keyboard are on. If not, you can try the "windons key" R key to call up the operation window, then enter "OSK" in the dialog box to call up the keyboard on the screen, select "open numeric keypad" in the options, and then click the OK button. Then check whether it is on through NumLock key, and the phenomenon is consistent with the appeal.Unlocking method 3 of laptop keyboard lockAnother simple inspection method is that sometimes it may be because your keyboard (external keyboard) is in poor contact. At this time, all you can do is turn on and off the laptop five times, so that you can release all the static electricity in the computer, then connect it to the keyboard and turn it on again. If it's really just a keyboard problem, then this problem can be eliminated. If the model is relatively new, many computers will have a FN key. If this key is combined with NumLock, it can also eliminate many computer keyboard lock errors.2 How to set the keyboard lock of notebook computer1. Restart the computer. During computer startup, press F2 to check whether BIOS settings can be entered.If the BIOS setting cannot be entered normally, it can be basically judged that the keyboard data connection is loose, and it needs to be sent to the local service network for inspection and maintenance.If you can enter the BIOS normally, it shows that it has little to do with the hardware. It is recommended to observe under what circumstances the keyboard will fail after entering the system.2. Press FN numlk in blue for notebook. Is either FN or shift or Ctrl numlk.

Analysis of System Composition and Architecture of LED Display Screen
Analysis of System Composition and Architecture of LED Display Screen
As a high-tech product, LED display has attracted great attention. The intelligent full-color display, which is controlled by computer and integrates light and electricity, has been applied in a wide range of fields. The pixel points adopt LED light-emitting diodes, and many light-emitting diodes are arranged in a dot matrix to form an LED array and then an LED screen. Through different LED driving modes, images with different effects can be obtained. Therefore, the advantages and disadvantages of LED driver chip play an important role in the display quality of LED display screen. LED driver chips can be divided into general chips and special chips.General purpose chips are generally used for low-end products of LED display screens, such as indoor single and dual color screens. The most commonly used general chip is 74HC595, which has the functions of 8-bit latch, serial shift register and three state output. Each channel can output 35mA non constant current at most.Because LED is a current characteristic device, that is, on the premise of saturated conduction, its brightness changes with the change of current, not with the change of voltage at both ends. The biggest feature of the special chip is to provide constant current source output, ensure the stable driving of LED and eliminate the flicker of LED. With the characteristics of high output current and constant current, it is suitable for occasions requiring high current and high image quality, such as outdoor full-color screen, indoor full-color screen, etc.LED driver chip series products for LED display smt5026.smt5026 has built-in CMOS shift register and latch function, which can convert serial input data into parallel output data format.Part II: system architecture of LED display screen(1) Display unitThis is the main part of the LED display screen, which is composed of luminous materials and driving circuits. The indoor screen is the unit display board of various specifications, and the outdoor screen is the unit box.(2) Main controllerThe function is to buffer, transform and reorganize the input RGB digital video signal, and generate various control signals.(3) Switching power supplyThe purpose is to change 220V AC into various DC to supply various circuits.(4) Transmission cableThe display data and various control signals generated by the main controller are transmitted to the screen body by twisted pair cable.(5) Scan controllerThe function of the circuit board is to buffer data and generate various scanning signals and duty cycle gray control signals.(6) Special display card and multimedia card (video card)In addition to the basic functions of the computer display card, the LED full-color display card also outputs digital RGB signals, line, field, blanking and other signals to the main controller. In addition to the above functions, the multimedia card can also change the input analog video signal into digital RGB signal (i.e. video acquisition).(7) Other signal sources and their external devices

Step 1: pull out the screwFirst turn the laptop over, and then remove the battery and the side of the laptop screen (remember to also open the screws hidden under the battery)Then, you will remove the keyboard screw that is usually located in the middle of the laptop (usually displays a keypad image) close to it to make your work easier)The last thing we have to do is disconnect the wire of the wireless antenna.On the HP dv9000 series, the wireless network card and memory are kept on the same plate, which gives us more space and makes us very easy.Find out which board hides your wireless card (it's harmless to open it all and view the contents below them in any way, because it's a learning experience)Once you find the network card and antenna wire with black, it winds out. Please note which wires go to which side of the card (I'm not sure of the importance of reconnecting them correctly, because they are only cut wires, and they won't close any circuits, but plug them back and attach things in the right way for the first time, ha ha)OK, now you can go to the top of the laptop.Step 2: remove the speaker frame and the annoying plastic cutting step.OK, so with the computer turned off and the battery removed from the device, press and hold the power button for 20 to 30 seconds to eliminate the remaining power. Capacitor, and then use a flat screwdriver to remove the speaker bezel from the device.Take your time, you won't break any plastic clips. We really want this unit to return together when it is finished.Step 3: screen screws and wiresOnce you remove the speaker bezel, you will see a (in my case) total of 6 wires protruding from the bottom of the screen into the laptop.From left to rightVideo cable, (cable for controlling all aspects of color and brightness such as LCD, backlight, etc.)The next step will be two thin lines that control the webcam on this displayOn the right side of the screen, you already have a wireless antenna cable and a webcam controller cable, and your replacement screen should already contain all of these.So just disconnect the laptop cable and connect it to the screen.If you don't care about these wires on the new screen, the screen may be wrong or the model may be small.You can consider taking the laptop screen apart and placing it horizontally (unfortunately, this may be troublesome, but it must be feasible).But go back to it, continue and pull out 2-3 or connect the 4 screws to the hinge of the laptop screen so that it can be gently lifted from the laptop.Now move the monitor away (but still tied to the laptop through the antenna cable)We can remove the keyboard, at the top of the keyboard, you will notice that the screws on the top of the 3 to 5 keyboards pull them forward and keep them apart(they will be different colors, so it's hard to keep them apart, but if you separate the screws in some way, it will make things easier), then gently lift the keyboard and pull it up (towards the screen), then tilt the keyboard so that you can see below it, and disconnect the cable connecting the keyboard to the laptop.Do not use this cable roughly. If you disconnect the keyboard cable when trying to fix the laptop screen, it will only cause problems and more money You may feel depressed in the whole room, = O ha ha, I don't want that.Step 4: serpentine antennaAfter unplugging the keyboard, the first thing to pay attention to is the of the wireless antenna(the only reason is to go so deep), so move on, release the wires from their small tracks and clips, and gently bend the end of the antenna into a line so that they can connect to the wireless network card at the bottom of the laptopRemember, if your wireless card has any unexpected twist or hook, how it will wind through, because you will need to reinsert the new antenna cable in one second.Step 5: throw it back.Once you release them, please continue and move your screen. It is broken and far away, but don't discard it in the future. The components on it may still be useful.Then grab your new monitor and start bending the wireless antenna lead back and locking it in place.Put the keyboard back in place and don't forget to reconnect the wires under the keyboard.Screw it back in place.(this is where we started to calculate the screws. We don't want to leave any screws. I hope you can remember their whereabouts well)Reconnect the video, microphone and camera wires to the laptop, and then screw the hinge of the laptop back to the laptop.Grasp the bezel of the laptop, fix it back in place, and then close the laptop,Turn it over and start replacing all the screws. Is there any left? Congratulations on winning!Slide the battery back into place (if not, connect the wireless antenna cable, just press it back into the slot). That's all. It's done. Open the suction cup again to see if you were cheated and bought another broken screen, or if you forgot to connect the wire correctly = P ha haIf it works properly, it means that you have successfully patted your back and waited for something. Otherwise, please break it so that you can regain new confidence and repair her = D

With the Rapid Development of Mobile Internet, the Production Qualification Rate of Display Screen I
XXX backlight panel manufacturing factoryWith the rapid development of mobile Internet, the software and hardware technology of smart phones have been rapidly improved. At the same time, the price is also developing in the direction of more and more civilians, which makes the development of smart phones in China more and more diversified and the scope of application more and more comprehensive, and plays an extremely important role in people's intelligent life.Mobile phone display screen is an important part of smart phone. The production qualification rate of display screen and the production quality of mobile phone play a very important role in the popularization of mobile phone. Unqualified mark line will lead to product display problems. The traditional mark detection is an artificial naked eye detection method. There is a phenomenon that the detection change range is too large due to the instability of the artificial naked eye, which leads to the problems of inaccurate detection and low efficiency.At present, many types of work requiring precise calculation have been replaced by automation equipment, and the visual inspection of backlight is no exception. Follow the Xiaobian:What problems can be solved?It mainly detects the mark line of the mobile phone backlight, including:Number of mark lines (excessive and missing);Mark line length, accuracy plus or minus 0.1mm;The distance from the mark line to the specified frame, with an accuracy of plus or minus 0.1mm;Camera assemblyDetection processTest effectTake two stations as an exampleTest conclusionFrom the early sample test results, the software can accurately detect the edge of each sample and the mark line on the product, and accurately calculate the length of each mark line, the distance between each mark line and the edge and the number of mark lines. The specific indicators are as follows:(1) Detection accuracy: 0.1mm (compared with the actual product, it is related to the marking and filling method, appearance and measurement benchmark, and there will be corresponding fluctuations)(2) Detection efficiency: it varies according to the number of mark lines, 20 for each piece, and the detection time is within 0.5s;(3) Product model: support multiple models of the same material, with the maximum size of 80 * 160mm.(4) Mark line color: white and black. The detection parameters need to be adjusted.

How to Make My Computer Display the Screen Full Size?
adjust your screen resolution... if you had adjust it to high and still the same.. get a video card the has a highest resolution.1. ???...My laptop display screen needs cleaning...???there are products available at computer stores, but they mostly are composed of alcohol and other agents, you can safely use Windex and a soft clothes to wipe the screen depending if its glossy or matt, be careful to not scratch the surface with a hard or coarse clothe. spray on the cloth and then wipe, if there are sticky smudge then try to get more windex on it but becaureful you dont get any inside the screen bezel.2. Utility to display on screen the currently pressed keysQiPress seems to work for me.There is a lite and a pro version at $30. The lite version is enough for my needs3. Laptop display screen won't light up?the only way that i comprehend to tell for specific if it is the backlight or inverter is to plug a regular solid backlight into the inverter. If it lights then it is the backlight, if no longer it is the inverter. The inverter is a miles less costly, ordinary restoration or it is going to be besides. The backlight section is way less costly yet is complicated (study high priced) to interchange except you pick to aim it your self. It frequently is not the two4. Why do we call a computer or TV display a "screen?I discovered a very helpful passage from the book, The Oxford Handbook of Management Information Systems: Critical Perspectives and New Directions(link takes you to the passage)The author notes that the word "screen" originates from the 14th century, andevolved from the Middle English word serene, from the Middle French escren, and from the Middle Dutch scherm. It is a word akin to the Old High German (eighth century) words skirm, which meant shield, and skrank, which meant a barrier of some kind. The word screen also suggests another interesting signification, further away from us in history. It is a word 'probably akin' (MW) to the Sanskrit (1000 BC)" words carman, which meant 'skin', and kn'z'nti, which signifies 'he injures' (MW). These are possible meanings from which the Middle Age words evolved. The Sanskrit clue suggests that the notions of protection, shield, barrier, separation arose, possibly within the older Proto-Indo-European language, as metaphors of the concept of skin-possibly that of human (or animal) skin.So there is a lot to do with protection and barrier which run through the evolution of the word. The author goes on to describe the chronological relations between the words:A barrier or a protection is something raised over and against another something. This 'other' something faces the barrier, as the wind faces the windscreen of a car, which means that the screen protects against something, to be excluded, that moves towards it. That which is moving towards the screen could have been understood as a projection (from the Latin word projectare, which meant 'to throw forward') over a surface-just like the arrows and bullets were projected over the shields, or like the heat is projected onto the fireplace screen. The screen protects and shelters (just as a skin. . . ) because it receives and holds the projection of that which is not to be received 'inside' the cover that the screen provides. But what happens when something stopped by the screen is allowed to pass through? The answer is that it was screened. This means that it was permitted to pass through that barrier, or that it simply passed through it. The screen as a barrier is now understood as a 'system for detecting [for example] disease, ability, attribute' (OPDT 1997: 681-2). This interpretation links, or so we hope, the three central themes of meaning attached to the word screen: hiding/protecting, projecting/showing, and testing/selecting (ibid.).The author goes on to argue that these three themes all have a central intent - a demand for our attention. They provide this table to help show this. P.270I think that should pretty much answer the question. The author has other interesting things to say on the word as well, and explains the phenomenology of the word and relates it to concepts like "the truth in seeing". Interesting stuff!

Aventk UV Color Changing Black Glue 1098 Can Effectively Solve the Reflection Problem of OLED Displa
Reflective problem of OLED display The core of OLED is a transparent organic semiconductor polymer, which can be made into a thin film and emit light by applying an electric field on both sides. Because the structure of OLED panel is very simple in theory, very thin products can be made. At present, the thickness of OLED display screen in mass production is only 0.95mm. Although OLED display is a self luminous product, after removing the backlight, there should be no problem of backlight leakage in theory. However, in terms of actual products, due to the existence of MF coating, there is still a problem of reflection around the edges of the display screen, as shown in the following figure:Therefore, how to solve the reflective problem of OLED display has become a concern of many manufacturers. In this regard, aventk has also studied and tested for many times, and finally determined that aventk 1098 series UV color changing black glue can solve this problem. Aventk UV color changing black glue 1098 can solve the problem. In solving the reflection problem of OLED display screen, most of them used UV black glue before. However, UV black glue needs to take into account UV light irradiation, so the blackness cannot be too deep, otherwise UV light cannot irradiate the cured glue. However, if UV glue black is not enough, it can not achieve good light blocking effect.To solve this problem, aventk 1098 series UV color changing black glue can be solved. Aventk UV color changing black glue contains aventk's exclusive NYX technology. NYX technology is aventk's unique UV light dyeing technology, which perfectly combines UV light with glue dyeing. It is a transparent color before UV curing and can well absorb UV light. After UV curing, it becomes black (or other colors). It not only meets the high efficiency of UV light curing, but also quickly completes the dyeing of glue. Put aventk UV color changing black glue is applied around the OLED display screen and between the screen and pol, which can greatly reduce the problem of reflection. fqj

The sensors will need to record at a very high data rate, on the order of petahertz. Every single pixel will be receiving all of the light that is in its field of view, and none of the light will be focused. Fortunately, light is not just photons, it's also electromagnetic waves. The sensors will behave like antennas, rather than eyes, passively collecting the radio waves at the wavelength of visible light.Radio signal sources can be tracked quite easily, by measuring the timing of a wave reaching multiple antennas. The same applies to all sorts of waves; an earthquake's epicenter is calculated by measuring the timing when the waves arrive at seismometers. We even have the same types of sensors built into our own human bodies. : Our ears can taking a wave and determine the direction that it came from, based on changes of intensity and timing. We have already proven the concept using vast antenna arrays to collect unfocused photons, to create a focused image. We imaged the supermassive black hole M87* using the Event Horizon Telescope.Of course, when astronomers use the term "photon" they do not just mean visible light; they mean any coherent electromagnetic wave. This image represents the peak of current engineering feasibility for synthetic aperture imagery. The EHT uses a Very Long Baseline Interferometry, which works in 450 GHz, using very narrowly calibrated equipment designed specifically to tease out the glow of the accretion disk at the wavelengths to detect event horizons around black holes. In order to get meaningful data, though, your sample rate needs to be at least twice the frequency of the signal rate, preferably more than 4 times the signal rate, or you start getting downsampling errors called aliasing. In order to record visible light, which has frequencies between 405 THz to 790 THz, you will need a sample rate that is at least 1.58 PHz.Due to limitations from the speed of light, and the time that it takes electrons to pass through silicon and copper in computers, this is just past the fastest speed that we can record data meaningfully.We would have to pass the data from several sensors in order to build up a meaningful synthetic aperture image from interferometry. We would need specialized recording technology that we just do not have yet.And, there's also the problem that LEDs are not designed to collect light, even though they are capable of doing it. .. just as sound coming out of a microphone would sound terrible, and sound recorded from speakers is also low quality. It would take several generations of iterating on the current science in order to use an LED-based computer monitor to record what is happening it a room, and it will always require specialized systems to just record the data in a meaningful way, much less process it into an image. It took several petabytes of data and 3 years of processing in order to build the EHT's image of M87*. It was faster to hand-carry the hard drives from the telescopes around the world to the datacenter, than it would have been to send the data over high speed internet links. It would take a lot of iterative work to miniaturize the chips necessary to do the calculations, but the technology just barely exists.Such a screen would be prohibitively expensive, as it's much easier to just put a lense in front of a cluster of photodiodes (i. e. , a webcam) and hide that in the corner of the screen, but those leave physical evidence... you can see the lense if you take the screen apart. It could be possible, with non-digital interferometry, to construct such an image of the room in real time. .. but that equipment barely fits in the basements of large telescope observatories, and requires cryogenic cooling. You would not be able to collect it clandestinely, and would be much cheaper (and higher quality) to use a webcam.
