What is the reason why there are ghost images on the LCD screen and how to solve it? [Copy link]

The segment code LCD screen is a customized product, in which: size, material, voltage, bias, viewing angle, operating temperature and other parameters are fixed before the mold is opened. The LCD screen has ghosting when it is lit, which is generally caused by the voltage supplied to the LCD screen being higher than the voltage of the LCD screen itself (for example: when the LCD screen is customized, the voltage is 5V, so it needs to be lit with a voltage of 5V. If a voltage higher than 5V is used, some things that should not be displayed on the LCD screen will be displayed, which is called ghosting) This content is originally created by Jingtuo, a netizen on the EEWORLD forum.

In addition to voltage, there should be other factors.

Some things that should not be displayed on the LCD screen will be displayed. What is the difference between ghosting and the shadow we usually talk about?

Yes, I just wrote down the common factors.
