The use of LCD screens has penetrated into every small detail in our lives, but in the industry, there is a common small problem that has always existed, and that is the problem of LCD screen flickering.
1. The frequency of the LCD display and the light source are similar, causing a flicker
The frequency of the TFT LCD screen is similar to that of the light source, causing the screen to flicker. This situation is very common. Because the frequency of different light sources is different, under certain circumstances, it is more common to flicker when the LCD screen and the artificial light source have similar frequencies. At this time, the best way is to do it. An artificial light source or LCD screen device to avoid the occurrence of flicker.
2. The frequency of the LCD display itself is too high, causing a flicker
The frequency of the LCD display itself is too high to cause the flicker. Generally, there are very few problems in real life that cause the device to flicker due to the high frequency. Human eyes have no flickering feeling for pictures exceeding 60hz, and the design standards of general LCD display screens are basically maintained on this data, so under normal circumstances, there will be no excessive frequency, but at the same time, it cannot be ruled out. The screen itself is malfunctioning. It is indeed a failure of the screen itself after measurement by related instruments. In addition to replacing the new monochrome LCD screen, it is to design the equipment-related software. A good way is to increase the OSC frequency of the IC and look at the flicker of the LCD screen. . Of course, the LCD display produced by our Sanjing Electronics has separate row and column drivers, and the setting of the driver chip can also be adjusted to solve the problem of splash screen.
