Abstract

The invention discloses an array substrate and a display panel. The array substrate comprises a plurality of sub-pixels, and each sub-pixel comprises a main region, a first sub-region, a second sub-region and four thin film transistors; the array substrate further comprises a gate line, a data line and a voltage dividing line, the first thin film transistor is used for driving the second sub-region to display, a second thin film transistor is used for driving the main area to display, a third thin film transistor is used for driving the first sub-region to display, and a fourth thin film transistor is electrically connected with the voltage dividing line and used for dividing voltage for the second sub-region. According to the invention, the channel length-diameter ratio of the second thinfilm transistor is set to be greater than the channel length-diameter ratios of the first thin film transistor and the third thin film transistor; and a drain electrode of the fourth thin film transistor is electrically connected with the voltage division line, so that the potential differences of the sub-pixels in the main region, the first sub-region and the second sub-region are different, andthe display panel obtains a wider viewing angle.

Description

technical field [0001] The present application relates to the field of display technology, in particular to an array substrate and a display panel. Background technique [0002] For a display panel in VA mode, the difference in birefringence of liquid crystal molecules at different viewing angles is relatively large, resulting in large viewing angle deviation. Currently, a multi-domain display mode is often used in some wide viewing angle liquid crystal displays to increase the viewing angle of the display. The multi-domain display mode refers to dividing multiple regions in one sub-pixel, and the deflection angles of the liquid crystals in different regions are different. Compared with the traditional single-domain display mode, the multi-domain display mode can reduce the The difference in contrast at different viewing angles caused by the same deflection angle increases the viewing angle. However, the existing wide-viewing-angle liquid crystal displays have limited impr...
