Display panel and displaying device

Abstract

The invention provides a display panel and a displaying device. The display panel comprises multiple pixel groups, each pixel group comprises a first pixel unit and a second pixel unit, wherein a control end of the first switch is coupled with a first scanning wire, a first end is coupled with a first data wire, a second end is coupled with a first sub pixel, a control end of the second switch iscoupled with the first scanning wire, a first end is coupled with the first data wire, a second end is coupled with a first primary pixel, the second pixel unit comprises a third switch and a fourth switch, a control end of the third switch is coupled with a second scanning wire, a first end is coupled with the first data wire, a second end is coupled with a second sub pixel, a control end of thefourth switch is coupled with the second scanning wire, a first end is coupled with the first data wire, and a second end is coupled with a second primary 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 a sub pixel region, the second and fourth switches are located ina primary pixel region, and the area of the sub pixel region is greater than that of the primary pixel region.

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
