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

Polarizer is an important part of LCD screen. With the emergence of special full matching technology, polarizers are more and more widely used in LCD. What role does polarizer play in LCD?   Polarizer is widely used in LCD industry, and LCD needs to use polarizer. Polarizer and liquid crystal play an important role in development. In the production process, two pieces of ordinary tempered glass are printed on the circuit, and then glued together and folded. Then the liquid crystal is injected into the middle of the two sides of the glass, and the polarizer is pasted on the top and bottom of the glass.   The upper and lower glass should be pasted with polarizer, but pay attention to the direction. If the lower polarizer filters the x-direction light, the upper polarizer can only filter the y-direction light. If the upper polarizer filters out the light in the Y direction and the lower polarizer filters out the light in the X direction, the user can see nothing. Although the LCD works normally, the polarizer is not visible to the naked eye. Now the LCD color screen is generally only on the film, not on the film, the product technology innovation.   People who have studied physics should know what polarized light is. The imaging of LCD must rely on polarized light. All liquid crystals have two polarizers close to the liquid crystal glass to form a liquid crystal sheet with a total thickness of about 1 mm. Without
