What About the Laptop Keyboard
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.

System Design of LED Display Screen
System Design of LED Display Screen
With the rapid development of science and technology, the development of traditional TV, newspaper and magazine media has lagged behind the development of outdoor media. Here we will introduce the system design of dot matrix LED dot matrix display.Composition of LED dot matrix displayComposition of LED dot matrix display: it is a new display device, which is composed of multiple LED's encapsulated together. In order to explain the principle of LED dot matrix display, a display system including hardware and software is designed and manufactured with single chip microcomputer as the control core. The circuit can realize various display forms such as rolling shutter, moving up and moving left of any number of Chinese characters through key control. It can be widely used in public places such as airports, shopping malls and hospitals for text advertising and information release. Moreover, it has the characteristics of small volume, simple circuit structure and easy implementation.LED dot matrix displaySystem hardware circuitThe hardware circuit of the display controller is mainly composed of three parts: serial communication interface, expansion of external memory, LED dot matrix display driver and interface circuit. Generally speaking, there are many contents to be displayed, so the external data memory must be expanded. Static data memory has the advantages of low cost, low power consumption and fast reading and writing speed. We use two pieces of static ram62256 data memory (64KB in total). Store all the content codes to be displayed in 62256.System software programSoftware program is the core of the whole control system. After the system main program starts, the system environment is initialized first, including setting serial port, timer, interrupt and port. The whole software design is mainly divided into two parts: display part and communication part.Communication part: the upper computer software adopts visual basic programming, and VB is used to provide a powerful communication control MSComm, which controls the message format and protocol setting of serial port and serial port communication, and directly uses the serial port of PC to send data. In order to realize the reliable communication between MCU and PC, both sides must have the same data format and baud rate. The use of the software is relatively simple. When using, you can use Microsoft Word to handle the content to be displayed (note that the width of the page setting should be the same as that of the LED dot matrix display), then select the select all command and copy command in the edit menu, and then run the LED display Download Software v1.1. Select the "clipboard" button in the interface, and the content to be downloaded can be displayed in the preview box, After checking, select the baud rate and connect to the serial port, click the "download" button, and you can download the display. Repeat the above operation when you need to modify or display new content. It is very convenient to use.Display part: use dynamic scanning to realize the control and display functions of Chinese characters, characters, images and data transmission on the display screen. The program divides the data memory into three areas: display buffer, data storage area and receiving buffer. The single chip microcomputer receives the data from the PC through the serial port interrupt, temporarily stores it in the receiving buffer, analyzes and processes it, saves it in the data storage area according to certain rules, and then extracts the data from the data in the memory according to the display mode sequence to display it in the display buffer. The display adopts progressive scanning. The real-time communication part of PC mainly uses the MCU serial port to interrupt the reception of data information and realize the data information transmission with the computer.

The Application Status of LED Display Screen, Why Should It Be Imported into GM (mssop Package)?
The Application Status of LED Display Screen, Why Should It Be Imported into GM (mssop Package)?
The development history of LED can be traced back to the 1970s. The earliest gap and GaAsP homogeneous junction red, yellow and green LEDs with low luminous efficiency have been applied to indicator lights, digital and text displays. Since then, the use of LED has entered a variety of application fields, including aerospace, aircraft, automobile, industrial application, communication, consumer products, etc., covering all sectors of the national economy and thousands of households. The application and development of LED can also be seen from the growth track of LED display industry. Including: 1. The LED luminous efficiency is improved. In order to achieve the same brightness, the LED current value can be reduced, so the service life of the power supply can be prolonged. 2. In addition, the size of LED lamps is getting smaller and smaller. From plug-in lamp (DIP) to surface paste lamp (SMD), there are even 0606 SMD lamps in the market. With such a development process, the dot spacing of LED display screen can be reduced, and it can also move from outdoor to indoor. Therefore, the process design of the overall display screen must be continuously refined. According to the current application specifications, outdoor screens are commonly used (see Figure 1): P10, p12, p16, P19, P20, p21, P22 and P26, especially P10 is the common specification of outdoor advertising screens; Commonly used indoor screens (see Figure 2): P3, p3.75, P4 and P5. Some manufacturers can achieve P1.5 and P2. Today, it can be seen that indoor advertising screens are widely used in subway stations (such as Beijing Sanyuanqiao station).2 Miniaturized packaging trend of LED driver chipsWith the rapid development of LED display screen industry in production technology, display screen manufacturers have been unable to use the past product high homogenization and price reduction competition strategy to obtain market share. In the face of various applications and market demand, such as ultra dense screen or rental screen, the design must be made to a higher standard in order to face the fierce market competition. It includes that the box structure shall be beautiful and the overall weight must be light and thin, which makes it easy for users to assemble and disassemble on site and saves assembly time; Even some manufacturers directly connect the data and power interfaces between the boxes without any wire connection between the boxes, so as to reduce the possibility of ash accumulation and reduce the occurrence of failure rate. Therefore, for the light and thin box design, the market has higher and higher requirements for the driving IC packaging technology. From the earliest SOP (accumulated product code is GF) packaging, SSOP (accumulated product code is GP) packaging and QFN packaging (accumulated product code is GFN), to mssop now (accumulated product code is GM) packaging, it can be found that the size lightness of LED driven IC is an inevitable trend, which also tests the ability of driving IC manufacturers in product design. They must expand their functions to the extreme in the limited chip area.3 Why import GM (mssop package)? What are the advantages of GM package?A. Advantages of GM (mssop) package replacing GP (SSOP) packageThe lamp driven two-layer plate scheme reduces the total module manufacturing cost by 7%As far as the current outdoor LED advertising screen market is concerned, the specification of P10 / 4 sweep is the mainstream. The use of GM encapsulated LED Driver IC, compared with the traditional GP encapsulated driver IC, can reduce the use of one layer of driver version; in addition, it can also be installed on one side, and it is not difficult to cut feet on the back, so as to simplify the overall production process and improve production capacity. The most important thing is to reduce the total cost of module production by 7%.Small package area is favorable for PCB routing designThe packaging area of GM is 37% less than that of GP. Therefore, whether it is for the PCB design of LED display screen of plug-in lamp (DIP) or surface mount lamp (SMD), the layout is simpler and the number of board layers can be saved.With the LED lamp, the luminous efficiency is improved and the optimum current value is matchedAs mentioned above, the luminous efficiency of LED lamps has jumped, so the outdoor LED display can use a smaller current to achieve the same brightness as that used in the past. According to the current market experience, the application current of outdoor LED display mostly falls at 20mA 10%. For example, the maximum current of GM packaged products such as accumulated mbi5120, mbi5124 and mbi515x is mostly set at 20 25mA, which meets the mainstream demand of the market Pin pin design is the same as GP packaging, simple import programThe pin pin function definition of GM package is exactly the same as that of GP package, so when converting the original GP package to GM package, it can be perfectly replaced only by slightly modifying the original PCB.B. Advantages of GM (mssop) package replacing GFN (QFN) packageImprove the yield of LED display products and reduce the occurrence of false soldering and tin connectionWhen using QFN packaging, the common problem is that the pin pin pin, heat dissipation pad and PCB pad of QFN packaging are prone to false soldering or poor tin connection between adjacent pin pins, resulting in an increase in the defect rate. Relatively speaking, GM packaging has low requirements for SMT process, which helps to reduce the production defect rate and reduce the cost of customer complaints and customer service.twelvePatch speed increased by 10% and production capacity increased rapidlyGM packaging patch speed is 10% faster than QFN packaging speed, which helps to improve the overall production capacity.Reduce the demand for high-tech manpowerGM packaging test and maintenance are easier than QFN, so it only needs ordinary technicians to operate, reduce high-end labor costs and make more efficient application of resources.At present, GM (mssop) packaging has been on the market for about half a year. In view of the common questions during import, the following summarizes the relevant SMT experience for manufacturers to refer to during import and accelerate the import speed:PCB relateda. Confirm whether pcbpad has been oxidized, and clean it with cleaning agent before going onlineb. If the PCB is not vacuum packed, it needs to be baked before going onlinec. Confirm the mark point on the board edged. The board needs to pass AOI and X-raySteel mesh relateda. The recommended thickness is 0.12mmb. Cleaning times: it is recommended to clean every 3 5 times after printingothera. BGA, CSP, QFP and other non vacuum packaging IC must be put into the oven for baking if the original packaging has been removed: 110 / - 5 24hr;b. Confirm and check the mounting pressurec. Before going online, the furnace temperature curve shall be obtained by using the furnace temperature plateMiniaturization is the driving force for the design of all consumer electronic products, and consumer electronic products are developing in the direction of light, micro and. The world's first computer covers an area of 1500 square feet and weighs 30 tons. It has developed into the pad in its hands, "big brick" Portable mobile phones have developed to today's smart phones; in response to the design orientation of LED display screen and the overall market demand, we can see the phenomenon that GP (SSOP) packaging replaced GF (SOP) packaging in the past. Therefore, it can be boldly expected that GM (mssop) packaging will also replace most GP (SSOP) packaging.The introduction of new GM packaging represents the improvement of LED display manufacturing process and also proves the progress in R & D capability. Whether GM packaging replaces GP packaging or QFN packaging, the quality of products can be improved. I believe that more and more GM use experience can make LED display manufacturing enter the next era.

1-Wire Bidirectional Level Converter (1.8V to 5V) Reference Setting
The designer requires 1-wire host IO to adopt open drain architecture and work at 1.8V. Most 1-wire slave devices cannot work at 1.8V. This application note introduces the reference design (RD) to realize the level conversion between 1.8V 1-wire host and 5V 1-wire slave. The reference is designed to drive a typical 1-wire slave device and realize level conversion by using max3394e level converter.introductionFPGA, microprocessor, ds2482-100 and ds2480b are common 1-wire host devices. 1-Wire/iButton The slave device is produced by Maxim, and the typical working voltage of this series of devices is 2.8V to 5.25V. In the past, the traditional 1-wire master and slave devices used 5V drain open circuit logic. Now, designers need 1-wire host IO to provide 1.8V drain open circuit logic. Most 1-wire slave devices can work safely at 5V, and most of them cannot work at 1.8V. A bidirectional level converter is needed to overcome this limitation. This reference design (RD) uses Maxim Max3394e bidirectional level converter is used to solve the problems in such applications.Level converterThe max3394e bidirectional level converter is packaged in 8-pin, 3mm x 3mm tdfn. With the help of its internal slew rate enhancement circuit, it can be ideal for driving large capacitive loads. The capacitive load of 1-wire slave devices is usually greater than 500pf. The VCC I / O pin of max3394e has 15kV HBM (body mode) electrostatic protection to protect the 1-wire host. 1-wire bus is usually used to connect the external world, and HBM protection is the basic requirement. It is recommended to use ds9503p at pull-up resistor (R3), optional strong pull-up circuit and 1-wire slave device to enhance ESD protection.Application circuitThe circuit shown in Figure 1 uses max3394e to realize bidirectional level conversion from 1.8V to 5V, and the system adopts open drain port. Figure 1. Circuit schematic diagram of 1-wire bidirectional level (1.8V to 5V) converter. Note that pin I / O VL and I / O VCC have 10K internal pull-up. The BOM (bill of materials) of the reference design is shown in Table 1. Table 1. Bill of materialsWaveform measurement / test resultsFigs. 2 to 5 are the results of testing the evaluation circuit board. The test conditions are:VL = 1.8VVCC = 5.0VCh1: 1-wire host (ow_master)OW_ Slave line length: 2.4m, max.The optional strong pull-up circuit in Figure 1 is not used in the test.Measure at room temperature only.Figure 2. The performance of max3394e can be seen from the 1-wire reset waveform. The online response pulse amplitude does not exceed 250Mv, which is lower than the 0.4V maximum voltage of the typical 1-wire host VIL. Figure 3. 1-wire write operation waveform, write "1" time slot, tlow1 conclusionThis reference design is used to realize 1.8V to 5V 1-wire bidirectional level conversion and drive typical 1-wire slave devices.
