Pixel structure and liquid crystal display panel

Abstract

The invention provides a pixel structure and a liquid crystal display panel. The pixel structure comprises a first public electrode and a second public electrode set, wherein a plurality of scanning lines and data lines are crossed and formed into a plurality of pixel units; each pixel unit is corresponding to each scanning line and each data line and comprises a main area electrode, a secondary area electrode and a thin film transistor; a grid electrode of the thin film transistor is connected with the scanning line corresponding to the pixel unit, a source electrode is connected with the data line corresponding to the pixel unit and a drain electrode is respectively connected with a main area electrode and a secondary area electrode; the main area electrode is corresponding to the first public electrode; the secondary area electrode is corresponding to the second public electrode set; different voltages are applied to the first public electrode and the second public electrode set, so that the liquid crystals in the pixel areas corresponding to the main area electrode and the secondary area electrode are deflected for different degrees. According to the pixel structure and the liquid crystal display panel provided by the invention, the structure is simple, the opening rate is increased and the color cast phenomenon is avoided.

Description

technical field [0001] The invention relates to the field of liquid crystal display panels, in particular to a pixel structure and a liquid crystal display panel. Background technique [0002] The existing VA (Vertical Alignment, vertical alignment) liquid crystal display panel has become a mainstream product in the market due to its advantages such as wide viewing angle and high contrast ratio. VA-type liquid crystal display panels generally have color shift problems, such as figure 1 Shown is a schematic diagram of an equivalent circuit of a pixel unit of an existing liquid crystal display panel using charge sharing technology. By dividing the pixel electrode of each pixel unit into two parts, the main area electrode and the sub area electrode, the main area electrode is driven by the thin film transistor T1, and the sub area electrode is driven by the thin film transistors T2, T3 and a shared capacitor C. Specifically, the liquid crystal display panel performs progressi...
