Although people often see color LCD screens nowadays, monochrome LCD screens are still needed for many devices in actual industrial production and life, such as in-vehicle products, industrial meters and other electronic devices. However, people also found a problem in the process of using monochrome LCD screens, that is, the LCD screen will always appear flickering during use, which affects people's use. So, what are the factors that cause the monochromatic LCD screen to appear flickering?
The frequency of the screen itself is too high, causing the screen to flicker
However, in real life, device flickering is rarely caused by excessive frequency. According to industry related personnel, people’s eyes have no flickering feeling for pictures exceeding 60hz, and the design standards of general monochrome LCD screens are basically maintained on this data, so under normal circumstances, the frequency will not be too high. However, it does not rule out that the screen itself is malfunctioning. However, it is indeed a malfunction of the screen itself after being measured by related instruments. In addition to replacing the new monochrome LCD screen, it is to design the software related to the device. The best way is to increase the OSC frequency of the IC and look at the LCD screen. The flickering situation. Of course, if the LCD screen has separate row and column drivers, it can also be adjusted by setting the driver chip.
The frequency of the monochromatic LCD screen is similar to that of the light source, causing the screen to flicker.
This situation is very common. Due to the different frequencies of different light sources, it is more common to flicker when the frequency of the LCD screen and the artificial light source are similar under certain circumstances. At this time, the best way is to do Artificial light source or monochrome LCD screen device to avoid the occurrence of flicker.
The reasons and solutions for the flashing of the monochromatic LCD screen are probably these. When dealing with it, you need to choose to find out the reason, and then make a reasonable solution based on the reason.
