Thin-film transistor array substrate, display panel and display device

Abstract

The invention provides a thin-film transistor array substrate. The thin-film transistor array substrate comprises a plurality of scanning lines, a plurality of data lines, a plurality of TFTs and a plurality of pixel electrodes, which are arranged on a substrate, wherein each pixel electrode is connected with the corresponding scanning line and data line through the corresponding TFT; the thin-film transistor array substrate has a double-scanning line pixel array structure; the plurality of data lines divide each scanning line in the plurality of scanning lines into a plurality of first scanning segments and a plurality of second scanning segments; the plurality of first scanning segments are connected with the TFTs; the plurality of second scanning segments are not connected with the TFTs; the first scanning segments and the second scanning segments are located between two adjacent data lines; the first scanning segments and the second scanning segments on each scanning line are alternately distributed along the length direction of the scanning lines; and the line widths of the second scanning segments are smaller than those of the first scanning segments. According to the thin-film transistor array substrate, the area of a pixel electrode can be relatively improved by reducing the line widths of the second scanning segments; and the aperture ratio of the pixel is improved. The invention further provides a display panel and a display device with the thin-film transistor array substrate.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a thin film transistor array substrate, a display panel and a display device having the thin film transistor array substrate. Background technique [0002] With the development of large-sized display panels, there is a so-called half source driving (HSD) structure in the pixel array of the array substrate. In the pixel array of the HSD structure, two columns of adjacent pixels share one data line, which can halve the number of data lines. For display panels, driver chips including gate driver chips (gate driver) and source driver chips (source driver) are essential, and source driver chips are more expensive than gate driver chips due to their complex structure, while gate driver chips are more expensive than gate driver chips. Since the HSD architecture can halve the number of data lines, the cost of the source driver chip can be reduced. [0003] Although the display panel a...
