Laptop Screen Analysis (I)


Laptop Screen Analysis (I) 1

When we consider the video performance parameters of notebook computers, we generally need to consider three factors: screen size, resolution and the performance of mobile display chip. Most users often focus on the screen size and resolution of notebook computers, and often ignore the performance of display chips. In fact, the performance of display chip plays a vital role in the video processing ability of a notebook computer. Therefore, when measuring the video performance parameters of notebook computers, we need to comprehensively consider these three. Screen size the screen size of notebook computer varies according to different types of notebook computers. Generally speaking, the display screen with large screen is easier to read. In the alternative desktop notebook, the display screen with large screen is generally selected. In the ultra light portable model, in order to be easy to carry, the display screen size is generally relatively small. With the introduction of the concept of portable media center, many notebook products now use LCD display with special aspect ratio. Or adopt ultra-thin display screen to reduce the volume of the whole machine. We often see that the so-called 14 inch TFT display screen is introduced in some promotional materials of notebook computers. In fact, the 14 inch here does not refer to the length, width or height of the display screen, but to the diagonal length of the display screen. That is, the distance from the low-end corner to the high-end corner of the display. Different from CRT display, the diagonal length here in LCD display is the size of visual grid. The following table shows typical LCD display sizes for different types of laptop configurations:

Resolution screen resolution refers to how many pixels are arranged along the length and width of the screen. Due to the display characteristics of LCD, LCD has the so-called original resolution, and its best resolution is its original resolution. Of course, you can also use other display settings lower than the original resolution on the LCD display. At the same time, some special algorithms can be used to make the LCD display higher resolution. However, the display effect of both resolutions is not as good as using the best resolution. Higher resolution can display more image details and provide greater visual range. However, too large resolution also has disadvantages: the font may become too small to read. This is a big problem for some people with poor eyesight. Of course, you can also take a simple method to change the system font to solve this problem. However, this practice may lead to some unpredictable consequences in some programs. The following table lists the common resolutions of different types of LCD displays:

  • How to Clean a Laptop Keyboard

    In this guide, you will learn to know how to clean a laptop keyboard without removing the keys. We like to keep munching on some snacks while using our laptop and the scrapes just fall on the keyboard. They stick into the keys making it hard to type and result in uncalled for delays in work if we keep fighting with the dirty and messy keys to keep working.

    The dirt accumulated in the keys over the time also gets sticky and hinders typing, so it is necessary to have a spotlessly clean laptop keyboard. Well, this is not something too difficult if you know what to do and which tools to use. Tools Required: Here is a list of stuff that you need to clean your laptop keyboard.

    1. USB keyboard vacuum cleaner 2. Compressed air 3.

    Alcohol 4. Micro-fiber cleaning cloth Get all these tools, and then you are good to go and clean your laptop keyboard. Here is how you need to use these tools to clean the keyboard to start enjoying the experience of clean and smooth keys.

    Step 1: Shut down the laptop and get ready The first step is to shut off the laptop and remove any cables and accessories from it. This is to make sure that any moisture does not harm your laptop's functioning when you turn it on again. 1.

    Place a towel or cleaning cloth at underneath the laptop so that all the dirt and debris falls on it and you do not have to clean the surface later on too. 2. Lift one side of the laptop to tilt is so that all the dirt and mess come out of it.

    Shake it a bit to take out any loosely stuck stuff in the keys. 3. Lightly brush a cloth over the keyboard to remove any bigger dust particles that stay even after shaking it.

    You can use a USB keyboard vacuum cleaner to clean laptop keyboard as it sucks the dirt and tiny chunks of stuff stuck in the keys and sides of the keyboard. These vacuum cleaners sometimes come with LED light bulbs too which help you locate any hidden dust particles too. All you need to do is to plug the vacuum cleaner in the USB port and let it do its magic while you slowly move it around on the surface of your laptop keyboard.

    Buying a USB keyboard vacuum cleaner is necessary because you need to clean the keyboard frequently. Usually, we recommend clean it once a month. The price of the USB keyboard vacuum cleaner is around $10.

    You can buy it from eBay or Amazon. If you do not have a USB keyboard vacuum cleaner, you can use Compressed Air to clean the keyboard. 1.

    Get a compressed air can from the supermarket and insert a small straw in it. The diameter of the straw has to be small so that the air comes out with greater pressure. 2.

    Release the air from a compressed air can result in short swift bursts to let the sticky stuff come out of the keys. It is better to direct the outlet of straw at the sides of keys to have a better and thorough cleaning. 3.

    This works even better if you tilt your laptop to a side and then treat the keys with compressed air from the can as it gets better access to tiny particles this way. Since you have removed all the visible impurities, it is time to clean off the ultra-small particles too. For this, a soft microfiber cloth is perfect since it lets the particles get adsorbed on its surface leaving the keyboard free of any pollutants.

    Just sprinkle a small amount of water on the microfiber cloth and its adhesive capacity will improve even more. Remember to sprinkle just a little bit of water as excessive water will seep in through the sides of the keys and cause harm to your laptop. A clean laptop keyboard not only has to be free of all the dust particles but also bacteria and other microorganisms.

    Soak some cotton in a solution of diluted alcohol and then drench it completely. After that gently rub the cotton over the surface of the keyboard and ta-da the keyboard is as good as new! Make sure that you follow these steps thoroughly, and you will be amazed by the clean and spotless surface of the keyboard that you will eventually get!

    Use an external keyboard. It wo not be warm, so the cat is not as likely to sit on it. If you leave for a longer time, you can simply unplug it.

    Then cover laptop keyboard with something, as in @Alexandre Aubrey's answer. An additional benefit - indeed, the reason I do it even though I do not currently have a cat - is that it's a lot easier to work with a full-sized keyboard than a laptop one. And then you can plug a 21" or so display into the laptop's external video port

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

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
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.

What Are the Components of LED Display_ Application Method of LED Display Screen
What are the components of LED displayLED display is a flat panel display, which is composed of small LED module panels. It is used to display text, image, video, video signal and other information. The components are as follows:1 LED unit board: it is one of the core components of LED display. The quality of the unit board directly affects the display effect of the display screen. The unit board is composed of LED module, driver chip and PCB circuit board. The LED module is actually composed of many LED light emitting points encapsulated in resin or plastic lattice.2 Connection: it can be divided into data line, transmission line and power line. The data cable is a flat cable used to connect the control card and the LED unit board. The transmission line is used to connect the control card and the computer. The power cord is used to connect the power supply, control card and LED unit board. The copper core diameter of the power cord connecting the unit board shall not be less than 1mm.3 Power supply: the power supply generally uses switching power supply, 220V input and 5V DC output. It should be pointed out that because the LED display screen belongs to precision electronic equipment, switching power supply should be used instead of transformer.4 Control card: we recommend using a low-cost strip screen control card, which can control a 1 / 16 scanned 256x16 point two-color screen and assemble the most cost-effective LED screen. The control card belongs to asynchronous card, that is, the card can save information without power off, and the information stored in it can be displayed without connecting to PC.Application method of LED display screenLED display screen can help a unit to show what they want to say and release some announcements and information, so as to facilitate visitors to understand some basic information of the unit.1. First of all, our equipment has been debugged normally. Turn on the power switch first.2. Open the icon on the computer and enter the operation page, as shown in the figure3.
