Abstract

The invention discloses a pixel driving structure, which comprises multiple sub pixel electrodes, multiple data lines and multiple scanning lines, wherein the multiple sub pixel electrodes are arranged in an array; and the multiple data lines and the multiple scanning lines are arranged in a crossed mode. The pixel driving structure is characterized in that at least one data line is electrically connected with at least three sub pixel electrodes with the same data signal voltage polarity, and in a row direction or a column direction, the sub pixel electrodes connected with the same data line are connected with different scanning lines; and when a frame of image is displayed, the voltage polarity of the data signals applied to each data line remains unchanged, and the voltage polarities of data signals applied to adjacent two data lines are opposite. The pixel driving structure provided by the invention reduces the data line use amount, Z inversion can be realized, and low cost and low power consumption are realized.

Description

technical field [0001] The invention belongs to the technical field of liquid crystal display, and more specifically relates to a pixel driving structure, a driving method and a display device. Background technique [0002] Liquid crystal display (Liquid Crystal Display, LCD) has many advantages such as light and thin, energy-saving, non-radiation, etc., so it has gradually replaced the traditional cathode ray tube (CRT) display. Currently, liquid crystal displays are widely used in high-definition digital televisions, desktop computers, personal digital assistants (PDAs), notebook computers, mobile phones, digital cameras and other electronic devices. [0003] Such as figure 1 As shown, it is a schematic diagram of a pixel driving structure of a traditional TFT (Thin Film Transistor, Thin Film Field Effect Transistor) LCD in the prior art. The pixel driving structure includes M data lines (DataLine, also referred to as SourceLine), N scanning lines ( GateLine, which can a...
