Description

technical field [0001] The present invention relates to a pixel structure and a method for generating a driving voltage in the pixel structure; in particular, a pixel structure for generating a driving voltage according to a common voltage signal and a method for generating a driving voltage in the pixel structure. Background technique [0002] In recent years, flat panel displays have developed more and more rapidly, and have gradually replaced traditional cathode ray tube displays. Today's flat panel displays mainly include the following types: Organic Light-Emitting Diodes Display (OLED), Plasma Display Panel (PDP), Liquid Crystal Display (Liquid Crystal Display; LCD), and Field Emission Display (Field Emission Display). Display; FED) and so on. The flat panel displays described above are composed of many pixels, so each pixel is one of the key basic components. [0003] Among them, the liquid crystal display is one of the flat panel displays with advantages of high res...
