Display panel and display device

Abstract

The present application provides a display panel and a display device. The display panel includes: a plurality of pixel groups, each pixel group includes: a first pixel unit, including: a first switch, the control end of which is coupled to the first scanning line, and the first end Coupled to the first data line, the second end is coupled to the first sub-pixel; the control end of the second switch is coupled to the first scan line, the first end is coupled to the first data line, and the second end is coupled to the first main pixel ; The second pixel unit includes: a third switch, the control end of which is coupled to the second scan line, the first end is coupled to the first data line, and the second end is coupled to the second sub-pixel; a fourth switch, the control end of which is coupled to connected to the second scan line, the first end is coupled to the first data line, and the second end is coupled to the second main pixel. The first and second switches are located in the same column, and the third and fourth switches are located in the same column. The first and third switches are located in the sub-pixel area, the second and fourth switches are located in the main pixel area, and the area of ​​the sub-pixel area is greater than or equal to the main pixel area.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a display device. Background technique [0002] Liquid crystal display devices have the advantages of low cost, low power consumption and high performance, and are widely used in fields such as electronics and digital products. However, the driving of the pixel units in the display device needs to be realized by driving the corresponding scanning lines and data lines through the gate driving circuit and the source driving circuit. With the increasing demand for panel size, resolution, and large viewing angle image quality, and further improving user experience and saving costs, various manufacturers have developed many manufacturing technologies related to the display field, such as GOA (Gate Driver on Array) circuit design, HSD (Half Source Driver, Half Source Drive) technology. [0003] HSD technology, which halves the number of data lines and doubles the num...

AI Technical Summary

Problems solved by technology

However, this technology also has certain defects. Because the same data line connects two columns of pixel units, and the doubled number of scanning lines shortens the scanning time of the pixel unit, it is prone to insufficient driving capability, inconsistent charging efficiency, and parasitic capacitance between pixel units. Problems such as unbalance and signal waveform delay and distortion, and cause the display device to appear large-view angle deviation, vertical bright and dark lines, etc.

If considering the multi-domain or multi-region display with main pixels and sub-pixels, HSD technology is even more difficult to realize
