Abstract: A LCD panel and a driving method thereof are disclosed. The LCD panel comprises a plurality of pixel units, each pixel unit comprising: a data line, a first scanning line, a second scanning line, a first switch, a second switch, and a pixel electrode. When the first switch is turned on, said pixel electrode receives data signal of said data line and has an electric potential. During the process of said second switch being critically turned on for a certain time period, the electric potential of said pixel electrode decreases gradually through said second switch. At the moment when said second switch is completely turned on, the electric potential of said pixel electrode is changed instantaneously to a reference electric potential of said common electrode through said second switch. According to the present disclosure, one pixel can present different voltages during different time of one frame, and thus the low color shift display effect can be realized. Moreover, the electric potential of the pixel electrode can be changed to the reference electric potential of the common electrode at the set moment, so that the black frame insertion can be realized.

Abstract: Disclosed is a pixel electrode and an array substrate. The pixel electrode comprises four pixel domains, each of which is divided into a first alignment unit and a second alignment unit. The first alignment unit and the second alignment unit can be used to form a first electric field and a second electric field respectively, and the first and second electric fields are different in intensity. The pixel electrode effectively reduces color distortions on a large-size liquid crystal display device observed from a large viewing angle as well as ensures an aperture ratio of a pixel, which enhances the competitiveness of a product.
