1-Wire Bidirectional Level Converter (1.8V to 5V) Reference Setting

(source: Keke house)Whether it is the functional computer era more than ten years ago, the current smartphone era, or the 5g era that is about to enter, the security of devices has always been a hot topic. The iPhone x launched by Apple two years ago won the hearts of many fruit fans with its unique ID design. It is from this generation of iPhone that the home key used for many years disappeared. At the same time, fingerprint identification is also a stranger to Apple's mobile phone, and "face ID" has replaced it and become the symbol of the new iPhone.Compared with apple, some Android phones have found the best of both worlds in recent years. Among them, Xiaomi digital series and Huawei mate series are not only equipped with 3D face recognition technology equivalent to the security of face ID, but also place the continued fingerprint recognition function at the bottom of the screen. BOE's breakthrough in LCD screen fingerprint technology makes screen fingerprint identification no longer the "patent" of OLED.Although the face ID unlocking method has higher security, through the survey of some users, more than 65% of users think that fingerprint unlocking is more attractive to them, because fingerprint unlocking is more convenient than face unlocking. However, more than 90% of users want the mobile phone to support both face and fingerprint unlocking methods. The reason is like what toy Dragon said, "I can't use it, but you can't do without it".But the new iPhone released by apple in the past two years has always adhered to face ID, just like a boyfriend who has entered the sage mode, without mentioning fingerprint identification. Recently, it was reported that apple is studying a full screen fingerprint recognition scheme. If this technology is mature, fingerprint recognition will return to the iPhone.

key word:Corning, touch screen, notebookThe new protective glass helps to prevent damage to the touch screen; Corning gorilla glass enters new marketsCorning gorilla glass NBT, the latest protective glass launched by Corning today, aims to protect the touch screen laptop display from scratches and other damages caused by daily use.Gorilla NBT glass is a unique screen protection solution launched by Corning for touch screen laptops. Touch has become the main way of interaction between users and devices, and with the increase of touch interaction, the potential risk of glass scratch is also increasing. When these equipment are in intensive use every day, scratches will lead to the breakage of protective glass. Corning gorilla NBT glass has stronger scratch resistance. In case of scratch, the scratch visibility is smaller and the residual strength is higher, which can prevent the damage of notebook computer display when using sodium calcium glass with poor performance.Consumers pursue thinner, smoother and lighter personal computers with touch function. The market research conducted by market research institutions on the next wave of touch technology shows that in the next few years, in terms of protecting the glass market, laptops with touch function may reach the market share of smart phones. Corning gorilla NBT glass brings the world's leading protective glass solution with low cost, scratch and damage resistance expected by consumers to this new mobile device market."As the preferred protective glass for global equipment manufacturers, Corning gorilla glass has now entered the emerging touch screen notebook computer market with its special performance," said James R. Steiner, senior vice president and general manager of Corning special materials department. "As the demand for touch screen laptops continues to grow, we believe Corning gorilla NBT glass can challenge the current performance of soda lime glass, and its scratch resistance is 8-10 times that of soda lime glass. In fact, customers can now get the best protection glass solution at only 1% to 2% of the retail price of a laptop, which comes from gorilla Solution. In short, we believe that if you don't use gorilla glass on your device, it's not good enough. "Similar to handheld devices or tablet devices, consumers' physical contact with touch screen laptops includes tapping, tapping, grasping and cleaning. These interactions with laptop devices every day may cause scratches on the protective glass and affect the user experience. Corning consumer survey shows that the complaint rate of scratched laptop screens is more than four times higher than that of other mobile devices. Changing the screen can be very expensive, sometimes as much as half the price of the entire laptop, and users have to wait a few days."As a leader in touch computers, Dell is always looking for the best materials to ensure that our laptop screens can resist collision and scratch," said Sam Burd, vice president of Dell PC products group. "We used Corning gorilla NBT glass in the new client device to be launched this fall, which further strengthened the reliability and durability of our products to maintain the leading position in the industry."Corning gorilla NBT glass is now available and is expected to be applied to several notebook products of several world leading computer brands later this year.For more information about Corning gorilla NBT glass, please visit.

QFN package (quad flat no leads) - QFN is the name specified by Japan Electronic Machinery Industry Association (JEDEC).Four side pinless flat package, one of the surface mount packages, is a new surface mount chip packaging technology with pad at the bottom, small size, small volume and plastic as sealing material. Because QFN package does not have gull wing lead like traditional SOIC package, and the conductive path between internal pin and pad is short, self inductance? S number and package body? How long does it last? Therefore, it can provide excellent electrical performance, and because there is no gull wing lead, it can reduce the so-called antenna effect and reduce the overall electromagnetic interference (EMC / EMI). In addition, it also provides excellent heat dissipation through the exposed lead frame pad, which has a direct heat dissipation channel to release the heat of the chip in the package. Usually, the heat dissipation pad is directly welded on the circuit board, and the heat dissipation via in the PCB helps to diffuse the power consumption of the multi harrier into the copper grounding plate, so as to absorb the heat of the multi harrier; It can also achieve better land sharing effect. At present, QFN package has been widely used in general mobile phones and laptops, but it is about to flourish in LED display.Comparison of heat dissipation, size and volume between QFN and SOPGenerally, the size of SOP used is 104 mm2 (8x13x1.9mm), while the relative size of QFN is only 16mm2 (4x4x0.9mm), which is only 6 7 times the size of SOP; It has greater flexibility in the design of some small spacing display screens.Thermal resistance Ja) the coefficient is SOP = 59 / W, QFN = 39 / W, that is, the temperature from the chip node to the surface at the power of one watt. The following is the calculation formula of thermal resistance commonly used in the industry:TJ= ja*PDTaTJ= jc*PDTc Ja= jc* caSymbols and units used in the formula TJ C: node (chip) temperature Tc C: actual temperature Ta C: ambient temperature PD W: power supply voltage JA ( C / W): heat transfer impedance from actual to external surface JC ( C / W): heat transfer impedance from node to actual Ca ( C / W): heat transfer impedance from actual to external surfaceIn other words, if the same return temperature and power consumption, the node temperature on the chip will be different due to different packages. For example: if the ambient temperature is 85 C and the power consumption of the chip is 0.5W, the temperatures of SOP and QFN are as follows:Design of lamp drive in oneDue to the two characteristics of small volume and good heat dissipation of QFN, in the past, the specifications below pitch 16mm of outdoor display screen will choose the design of lamp drive separation because of the limitation of PCB board size routing and heat dissipation; That is, the LED light board and the driver chip board are placed on two to three different PCB boards respectively, and then connected with each other through connectors and cables. Although this design can solve the heat dissipation problem, the inductive effect generated through the connectors and wires may greatly reduce the color resolution of the display screen, and the inductive effect will also increase the chance of electromagnetic interference. When using QFN design; Because of its small size and no heat dissipation problem, the chip can be placed in the gap of the LED lamp. Therefore, it does not need to use more PCB boards and transmission lines. It is simpler in design and its cost can be reduced. Similarly, if the QFN design is used for the indoor display screen, the heat dissipation problem can also be greatly improved.

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

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.

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!
