When customers use LCD, what should they pay attention to?

The following are the precautions for LCD module operation:   If the display screen is damaged and the internal LCD leaks, do not let it enter the mouth. If it gets on clothes or skin, wash it quickly with soap and water. In order to reduce static electricity, do not carry out assembly and other work in dry environment. The LCD module has a film to protect the display screen. Be careful when removing this protective film as it may generate static electricity. The display screen is made of glass. Do not apply mechanical impact, such as falling from height. It must be grounded correctly. Minimize electrode corrosion. Water droplets, moisture condensation or current in high temperature environment may accelerate electrode corrosion. At low temperature, liquid crystal solidification will lead to directional defects or bubbles. When the liquid crystal module is subject to strong vibration at low temperature, bubbles will also be generated. If the LCD module works for a long time and displays the same pattern, the pattern will remain on the screen like a phantom, and there will be subtle contrast differences. If you want to regain the normal working state, you can temporarily stop using it for a while. It is worth noting that this phenomenon will not have an adverse effect on the reliability of the performance.

What are the pixels of LCD?

Pixel is a kind of unit. Generally speaking, it is invisible to the naked eye. How can we see the pixels of LCD? That is, if the image of LCD is magnified several times, many small square dots will be found. These small square dots are actually the so-called pixels.   The LCD splicing unit of LCD is a full-color screen, and red, green and blue are the primary colors of colors. Because LCD has many colors to realize, it needs to combine the red, green and blue lights to form pixels.   The pixel of LCD is a unit used to calculate the digital impression. Just like the photo taken, the digital impression also has continuous tone. If you enlarge the impression several times, you will find that these continuous colors are actually composed of many small dots near the color.   In addition, the pixels of LCD include real pixel display and virtual pixel display. The two technologies are different. The virtual display adopts virtual pixel technology, that is, LCD multiplexing technology. The same LCD light-emitting tube can be combined 4 times with adjacent LCD light-emitting tubes (down, down, left, and right combinations). Generally speaking, the pixel is a unit. The pixels of the current LCD display are 1920 * 1080, and the pixels of the Department display can be as high as 3840 * 2160. The higher the pixel, and more clearer the picture will be.

Why does LCD flash? What’s the solution?

With the wide application of LCD in vehicle products, instruments and other electronic products, there will always be flashing in the process of use, which will affect the use of customers. What we should do at this time? Now we would like to share with you the causes and solutions of LCD screen flashing: The frequency of the LCD screen itself is too high, resulting in the flash screen. However, in real life, it is rare for the device to flash due to high frequency. According to the industry technical personnel, people’s naked eyes have no sense of flicker for images over 60Hz, while the design standard of general LCD screens is basically within this data range, so under normal circumstances, the frequency will not be too high, but at the same time, the screen itself will not be excluded from failure. After testing by relevant instruments, it is really the fault of the screen itself. In addition to replacing the new monochrome LCD screen, it is to design the software related to the equipment. LCD flash screen solution: the best way is to increase the OSC frequency of IC to see the flash of LCD screen. Of course, if the LCD has separate row and column drivers, it can also be adjusted by setting the driver chip.   The frequency of LCD is close to that of light source. This is very common. Because the frequency of different light source is different, in some specific cases, when the frequency
