CHARGE-SHARING-TYPE PIXEL STRUCTURE

摘要

A charge-sharing-type pixel structure (1) comprises a first subpixel (11) and a second subpixel (12). Each of the subpixels comprises a transistor (TFT1, TFT2), and the second subpixel (12) additionally comprises a third transistor (TFTS) and a top gate electrode (TG). When the third transistor (TFTS) is opened, a liquid crystal capacitor (Clc1) of the first subpixel (11) changes the original gray-scale voltage by sharing charges with other capacitors. The top gate electrode (TG) changes the critical voltage of the third transistor (TFTS) in accordance with a bias signal, and then adjusts the change degree of the gray-scale voltage of the liquid crystal capacitor (Clc1) of the first subpixel (11).
