Abstract

The invention provides a circuit structure of an array substrate. The circuit structure comprises multiple grid lines, multiple data lines, a pixel matrix and multiple thin film transistors. Each grid line is connected with grids of one row of thin film transistors to control a row of sub-pixels, each sub-pixel is connected with one main data line and one auxiliary data line through one thin film transistor, each main data line is connected with a main pixel region through one thin film transistor, each auxiliary data line is connected with one auxiliary pixel region through another thin film transistor, and voltage of data signals input by the main data lines is larger than that of data signals input by the auxiliary data lines. Large-view-angle color cast compensation of a liquid crystal display panel is achieved, and the problem that the aperture ratio of the liquid crystal display panel is decreased is effectively avoided.

Description

【Technical field】 [0001] The invention relates to the field of liquid crystal display, in particular to a circuit structure of an array substrate. 【Background technique】 [0002] Liquid crystal display (Liquid Crystal Display, LCD) and other flat display devices are widely used in mobile phones, televisions, personal digital assistants, digital cameras, notebooks, etc. Various consumer electronic products such as computers and desktop computers have become the mainstream of display devices. Most of the liquid crystal display devices currently on the market are backlight liquid crystal displays, which include a liquid crystal display panel (TFT-LCD) and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is controlled by electrifying or not, and ...
