LCD driving method The liquid crystal display is due to the application of an electric field on the display pixel, and this electric field is generated by the synthesis of the potential signals on the two electrodes before and after the display pixel Liquid Crystal Display. It is very easy to establish a DC electric field on the display pixel, but the DC electric field will This leads to the chemical reaction of the liquid crystal material and the aging of the electrodes, thereby rapidly reducing the display life of the liquid crystal. Therefore, an AC drive electric field must be established, and the DC component in this AC electric field is required to be as small as possible. Usually, the DC component is required to be less than 50mV. In practical applications, due to the use of digital circuit drive, this AC electric field is established by pulsed voltage signals. The strength of the AC electric field on the display pixel is represented by the effective value of the AC volta…
