Abstract

The embodiment of the invention provides a pixel unit, an array substrate, a liquid crystal display panel, a device and a driving method, relates to the technical field of a liquid crystal display, and solves the problems that a display greenish phenomenon and a picture flickering phenomenon exist when the existing liquid crystal display device displays an image. According to the embodiment of the invention, the pixel unit is internally provided with two pixel electrodes and each pixel electrode is respectively controlled by a corresponding thin film transistor, so that a voltage difference between the two pixel electrodes can be used for controlling the deflection of liquid crystal molecules; and influences on voltage on the pixel electrodes of the pixel unit in the array substrate are not caused so that the phenomenon that the display is greenish is avoided. Furthermore, when the pixel unit is closed, the two thin film transistors of the two pixel electrodes are respectively controlled to have the same power leaking capability, so that the voltage difference between the two pixel electrodes keeps stable and the picture flickering phenomenon is prevented.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a pixel unit, an array substrate, a liquid crystal display panel, a device and a driving method. Background technique [0002] At present, each pixel unit in the array substrate of a liquid crystal display device is driven by applying a voltage to the pixel electrode covering the pixel unit, so that an electric field is formed between the pixel electrode and the common electrode, so that the liquid crystal molecules in the pixel are deflected to a certain extent by the electric field. The angle to achieve the passage and cut-off of light. [0003] The common electrode is used to provide a unified common voltage V for all pixel units -com ; The pixel electrode is used to provide the pixel voltage V to the corresponding pixel unit -pixel , the magnitude of the voltage is used to control the amount of light passing through the pixel unit. When a liquid crystal disp...
