Problems solved by technology

[0006] Although the above-mentioned existing TFT array substrate using 2D1G technology can improve the color shift, this design needs to double the number of data lines, which not only increases the cost of the driver IC, but also causes congestion in the Fanout area. Increase resistance-capacitance delay (RC), reduce charging efficiency, and affect product competitiveness

Abstract

The invention provides a TFT (thin film transistor) array substrate. Compared with conventional TFT array substrates adopting the 2D1G technique, the TFT array substrate increases the number of scanning lines, so that the number of data lines is decreased by half, the data lines are divided into main data lines (MD) and sub data lines (SD), main areas of sub-pixels located at both sides of the main data lines (MD) are controlled by the main data lines (MD), sub-areas of the sub-pixels located at both sides of the sub data lines (SD) are controlled by the sub data lines (SD), and two GOA (Gate Driver on Array) drive circuits are respectively arranged at the left side and right side of a display area to bilaterally drive all the scanning lines. The TFT array substrate not only can improve the colour shift problem of VA (Vertical Alignment) type liquid crystal display panels, but also can ensure charging efficiency and reduce the cost of liquid crystal panels.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a TFT array substrate. Background technique [0002] A Liquid Crystal Display (LCD) has many advantages such as a 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 notebook computer screen, etc., occupy a dominant position in the field of flat panel display. [0003] Generally, a liquid crystal display panel is composed of a color filter substrate (Color Filter, CF), a thin film transistor array substrate (Thin Film Transistor Array Substrate, TFT Array Substrate), and a liquid crystal layer (Liquid Crystal Layer) disposed between the two substrates. Composition, and set pixel electrodes and common electrodes on the opposite inner sides of the two substrates, and control the liquid crystal molecules to change direction by applying a voltage, and refract...
