Abstract

The invention discloses a pixel structure capable of reducing the vertical crosstalk phenomenon, which comprises a substrate, a scanning line, a data line group, an active component and a pixel electrode, wherein the substrate is provided with a display area and a periphery area arranged beside the display area, the display area includes at least one sub-pixel area; the data line group is arranged on the substrate and positioned at one side edge of the sub-pixel area and is staggered with the scanning line to form at least one first staggering area, and the data line group comprises a first data line and a second data line which are mutually staggered with each other to form at least one staggering area. When the first data line and the second data line are respectively given signals with different polarities, one single side of the pixel electrode is provided with the data line with two different polarities. Thus the pixel structure causes different distance between the pixel electrode and the data lines at the two sides due to technology offset, the pixel electrode and a coupling capacitor of the data line arranged at the same side can mutually neutralize, thereby reaching the purpose of reducing the vertical crosstalk phenomenon.

Description

technical field [0001] The present invention relates to a pixel structure, and more particularly to a pixel structure capable of improving vertical cross-talk of a liquid crystal display. Background technique [0002] Generally speaking, the pixel structure of the liquid crystal display includes scan lines, data lines, active elements and pixel electrodes. In the pixel structure, if the area of ​​the pixel electrode is designed to be larger, the aperture ratio of the liquid crystal display can be increased. However, when the pixel electrode is too close to the data line, the stray capacitance between the pixel electrode and the data line (capacitance between pixel and data line, Cpd) will become larger. In this way, when the switch element is turned off, the voltage of the pixel electrode will be affected by the signal transmitted by the data line, so a so-called cross-talk effect will occur, which will affect the display quality of the liquid crystal display. [0003] In ...
