Abstract

The invention relates to a pixel unit, a pixel array and a liquid crystal panel thereof; each pixel unit comprises a first switch, a second switch and a third switch; the first switch and the second switch are electrically connected with the same data line and the same scanning line, the third switch is connected with the second switch in parallel, and the third switch is electrically connected with the same scanning line; the main pixel electrode is electrically connected with the first switch; the sub-pixel electrode is electrically connected with the second switch and the third switch; thecoupling electrode is electrically connected with the second switch and the third switch; and the third switch is also electrically connected with the common line. By adding the third switch and connecting the third switch and the second switch in parallel, the charge and discharge speed of the second storage capacitor is increased, the charge release capacity of the second storage capacitor is enhanced, and residual images can be improved.

Description

technical field [0001] The invention relates to the field of liquid crystal display screens, in particular to a pixel unit, a pixel array and a liquid crystal panel thereof. Background technique [0002] Liquid Crystal Display (LCD) has many advantages such as thin body, power saving, and no radiation, and has been widely used, such as: LCD TV, mobile phone, personal digital assistant (PDA), digital camera, computer screen or Laptop screens, etc., dominate the field of flat panel displays. [0003] The current mainstream liquid crystal display panel is composed of a thin film transistor array substrate (Thin Film TransistorArray Substrate, TFT Array Substrate) and a color filter (Color Filter, CF) substrate, and between the TFT substrate and the CF substrate Fill the liquid crystal. The direction of the liquid crystal molecules is controlled by electrification or not, and the light from the backlight module is refracted to produce a picture. [0004] Among them, one side ...
