Array substrate and driving method of pixels

Abstract

The invention provides an array substrate and a driving method of pixels. The array substrate comprises a grid line and data lines, the grid line and two data lines define a pixel area, two thin film transistors are formed at a crossing position, and pixel electrodes arranged at intervals are arranged in the pixel area. A first thin film transistor in the two thin film transistors is connected with a first pixel electrode, and a second thin film transistor is connected with a second pixel electrode. The array substrate is characterized in that equal voltage with opposite polarities are exerted onto the first pixel electrode and the second pixel electrode respectively through the first thin film transistor and the second thin film transistor. An embodiment of the array substrate and the driving method of pixels can avoid a phenomenon that image display is uneven due to leaping voltage caused by coupling capacitance between the data lines and the pixel electrodes.

Problems solved by technology

In the pixel area of ​​TFS mode, a pixel area is formed by the intersection of a gate line (Gate) and two data lines (Data), that is, a 1G2D structure; usually, the data line of the pixel area is connected to the source, and the data line The voltage is applied to the line by the driving circuit, and the signal is transmitted to the pixel electrode through the TFT switch; however, in the array substrate in the new TFS mode, the two data lines will respectively generate coupling capacitance with the pixel electrode, and for two data lines with the same voltage As far as the line is concerned, the coupling capacitance between the data line and the pixel electrode is the sum of the coupling capacitances between the two data lines and the pixel electrode respectively. Due to the existence of the coupling capacitance, the signal transmitted from the data line to the pixel electrode has A certain delay, resulting in problems with the screen display
