Abstract

The invention discloses an LCD array substrate, an LCD panel and an LCD pixel circuit. The LCD array substrate includes: a substrate, a plurality of gate lines and data lines formed on the substrate, and the gate lines cross the data lines. A plurality of pixel units are formed, and a pixel electrode is formed in each pixel unit. The first thin film transistor also includes a connection switch controlled by a gate line, and the connection switch is controlled to be turned on, so that the pixel units located in the same column , the electrical connection between the pixel electrodes of the pixel units in the upper row and the pixel electrodes in the same column and the lower row of pixel units. In the present invention, by adding a connection switch for each pixel unit, the pixel electrodes of the previous row of the current row of pixel units are connected with the pixel electrodes of the next row to increase the capacitance, thereby reducing the feed-through voltage and reducing the risk of afterimages.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to an LCD array substrate, an LCD panel and an LCD pixel circuit. Background technique [0002] LCD (Liquid Crystal Display, liquid crystal display) uses the change of the electric field strength clamped on the liquid crystal molecules to change the orientation of the liquid crystal molecules to control the intensity of light transmission to display images. Currently, liquid crystal displays have been widely used in various terminal display devices of large, medium and small sizes due to their characteristics of light weight, small volume, and thin thickness. The LCD is mainly composed of an array substrate and a color filter substrate in the box. The array substrate is formed with gate lines, data lines, pixel electrodes and thin film transistors. Each pixel electrode is controlled by a thin film transistor. When the thin film transistor is turned on, the pixel electrode is in...
