Liquid crystal display static driving method

The static driving method is the most basic method to obtain the best display quality, and it is suitable for driving pen-segment liquid crystal display devices. In the electrode structure of this type of liquid crystal display device, when multiple digits are combined, the back electrodes BP of each position are connected together TFT LCD module. In the circuit of the static driving method, the pulse signal of the oscillator is directly applied to the back electrode BP of the liquid crystal display device after frequency division; and the pulse signal of the segment electrode is synthesized by the display selection signal and the timing pulse LCD TFT.

When a certain display pixel is selected for display, the phase difference of the pulse voltage of the two electrodes on the display pixel is 1800, and a 2V voltage pulse sequence is generated on the display pixel, so that the display pixel exhibits display characteristics; when a certain display pixel is non-display When selected, the pulse voltages of the two electrodes on the display pixel are of equal phase, and the synthesized voltage pulse on the display pixel is 0V, so as to achieve the display effect OLED Display Module. This is the static driving method. In order to improve the contrast, the voltage of the pulse should be adjusted appropriately LCD Display Module.
