Embodiment 1

[0079] Taking a 55UHD product as an example, the length of the second section of the pixel electrode is designed to be L=25μm (calculated by the formula based on the previous pixel simulation data), the width of the second section d1=2μm, and the length of the first section L1=5μm. Techwiz software simulates the capacitance of the pixel electrode, and the results are as follows:

[0080]

[0081] According to the above table, when the offset distance of the pixel electrode is 0.8 μm, the jump voltage ΔVp of the pixel electrode designed by the prior art is 59.9mV, and the voltage difference 2ΔVp between the pixel electrodes of two adjacent rows is 119.8mV , corresponding to the voltage difference displayed as 10 gray levels (12mV / gray level near the L127 gray level), based on 8 gray levels, horizontal stripe defects will appear on the above-mentioned pixel electrodes.

[0082] However, when the offset distance of the pixel electrodes in this embodiment is 1.2 μm, the jump vo...

Abstract

The invention discloses a pixel structure, an array substrate and a display panel. The pixel structure includes: a gate line extending along the first direction; a data line extending along the second direction, the gate line and the data line define a pixel unit; and a pixel electrode, the pixel electrode includes a display electrode part and at least one capacitance compensation group, Each capacitance compensation group includes a pair of capacitance compensation parts, the display electrode part is located in the pixel unit, the two capacitance compensation parts in the same capacitance compensation group are respectively located on both sides of the display electrode part, and each capacitance compensation part includes each other The connected first segment and the second segment, the first segment extends along the first direction and crosses the data line, is directly connected to the display electrode part, and the second segment extends along the second direction. Therefore, the display panel using the pixel structure can significantly improve the horizontal stripe defect caused by the offset of the pixel electrode, and improve the production yield and display effect of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular, to a pixel structure, an array substrate, and a display panel. Background technique [0002] With the continuous development of display technology, liquid crystal display screens have been used in all aspects of people's lives, such as mobile phones, computers, televisions, watches, electronic tags, and the like. Among them, the liquid crystal display adopting the advanced super-dimensional field switching (ADS) structure has become a popular display mode due to its advantages of wide viewing angle, fast response speed and high contrast ratio. In order to improve the pixel light efficiency and product transmittance of TV products, the ADS liquid crystal display adopts the pixel design scheme of shrinking the common electrode and expanding the pixel electrode to improve the light efficiency and make the TV products have higher display quality. [0003] However, the pixel s...
