Abstract

The invention discloses a display panel, which belongs to the field of display technology. The display panel includes: touch electrodes, criss-cross scanning lines and data lines, a plurality of pixel units defined by intersections of the scanning lines and data lines, and a plurality of compensation signals line group; the touch electrode is divided into several independent touch electrode blocks, and the compensation signal line group is set corresponding to the disconnection of the touch electrode. By forming a parasitic capacitance with the touch electrode, the touch electrode block is compensated The voltage deviation caused by the jump of the scanning signal avoids horizontal stripes near the junction of the touch electrodes.

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...
