Array substrate and liquid crystal display panel

摘要

The present invention provides an array substrate and a liquid crystal display panel. Wherein, in the array substrate, each pixel unit comprises a first pixel electrode, a second pixel electrode, and a third pixel electrode. And each pixel unit comprises a first control circuit and a second control circuit. The first control circuit affects the first pixel electrode, so that the first pixel electrode is under the state of displaying the image corresponding to the black screen in the 3D display mode. The second control circuit affects the second pixel electrode and the third pixel electrode to change the voltage difference between the second pixel electrode and the third pixel electrode. By the above way, the present invention can minimize the color difference in wide viewing angle, improve the opening ratio in the 2D display mode, and reduce the crosstalk of the two eyes signal in the 3D display mode. Furthermore, it can reduce the amount of the data drivers and reduce the costs.
