Factors that cause the LCD screen to flicker?

We often encounter the phenomenon of LCD screen flickering, which is generally related to the following factors:
1. The frequency of the Icd display itself is too high, causing the screen to flicker

If the frequency of the LCD display itself is too high, the screen flicker phenomenon will occur, but in reality, this phenomenon rarely occurs. For more than 60hz screen flickering, the eyes cannot feel it. The display standard of the general LCD display is in accordance with the this parameter design. If the screen itself fails, in addition to replacing a new LCD screen, the software related to the device should also be designed. The best way is to increase the OSC frequency of the IC to see the flickering of the LCD screen. If the LCD display has a separate driver, you can also adjust the settings of the driver chip to solve the problem of the splash screen.

The problem of signal interference
1. Whether the cable connecting the LCD display has no shielding coil, if there is no anti-interference color protrusion, it will also interfere with the screen.
2. Check whether there is interference nearby (such as high-power audio, power transformers, etc.) LCD monitors are easily interfered by strong electromagnetic fields, and sometimes screen jitter is caused by electromagnetic field interference near the LCD Monitor.
3. In order to eliminate the interference around the LCD display, you can move the device to an empty place, restart the machine and test if the screen shake disappears, indicating that there is electromagnetic field interference in the original place of the device, please move the device that may interfere. go.
