Description

technical field [0001] The present invention relates to a method for driving a pixel (that is, a pixel, hereinafter referred to as a pixel), in particular to a method for driving a pixel of a liquid crystal display panel. Background technique [0002] Different from the 180-degree full viewing angle of a CRT display, the viewing angle of a liquid crystal display device is limited due to the deflection characteristics of liquid crystal molecules. Generally, the definition of the viewing angle of a liquid crystal display device refers to the visible range with a contrast ratio greater than 10, that is to say, the viewable viewing angle under this specification can only ensure brightness (or contrast) characteristics, but cannot guarantee color reproducibility. [0003] Such as figure 1 As shown, a typical liquid crystal display panel mainly includes a thin film transistor (hereinafter referred to as TFT) substrate 10, a color filter substrate 20 located above the TFT substrat...

Problems solved by technology

However, these two methods require each row of pixels or each column of pixels to use an additional common line or scanning line, which makes the driving circuit complicated.

[0009] This shows that above-mentioned existing liquid crystal display, liquid crystal display panel obviously still have inconvenience and defect in structure and use, and urgently need to be further improved

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but no suitable design has been developed for a long time, and there is no suitable structure for general products and devices to solve the above-mentioned problems. This is obvious. It is a problem that relevant industry players are eager to solve
