Abstract
A liquid crystal (LC) array substrate includes a number of pixel regions, each pixel region includes a main region, a sub-region, and an adjustment thin film transistor (TFT), the adjustment TFT adjusts a ratio of voltage of the main region and the sub-region to achieve a LCS design. The main region comprises a first TFT and a main region array common electrode lead wire, the sub-region comprises a second TFT and a sub-region array common electrode lead wire, and the main region array common electrode lead wire and the sub-region array common electrode lead wire are electrically isolated. The main region array common electrode lead wire of all pixel regions of the LC array substrate are connected to a main region conductive pad, the sub-region array common electrode lead wire of all pixel regions of the LC array substrate are connected to a sub-region conductive pad.
