Abstract

The invention discloses a display panel and belongs to the field of display technologies. The display panel comprises a touch electrode, scanning lines, data lines, a plurality of pixel units, and a plurality of compensation signal groups; the scanning lines and data lines are arranged in a crossing manner; the plurality of pixel units are defined by means of the intersection of the scanning linesand the data lines; the touch electrode is segmented into a plurality of independent touch electrode blocks; the compensation signal line groups are corresponding to the disconnection portions of thetouch electrode respectively; parasitic capacitance is formed between the compensation signal line groups and the touch electrode so as to compensate voltage deviation on the touch electrode blocks caused by the jumping of the scanning signals, and therefore, horizontal stripes near the border of the touch electrode can be avoided.

Description

technical field

[0001] The invention belongs to the field of display technology, and in particular relates to a display panel.

[0002] technical background

[0003] The structure of a conventional self-contained in-cell touch display panel is as follows: figure 1 shown. The touch electrode 5 is divided into several independent touch electrode blocks, each touch electrode block corresponds to a plurality of pixel units, each touch electrode block is connected to the touch signal transmission line through the touch electrode connection hole 6 4. The touch signal transmission line 4 is connected to the IC. When in the display stage, the touch signal transmission line 4 inputs the common electrode signal, the touch electrode 5 is used as a common electrode, and an electric field is formed between the touch electrode 5 and the pixel unit 8 to drive the liquid crystal display. When in the touch stage, the touch signal transmission line 4 inputs the touch sensing signal, and the...
