Embodiment Construction

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described through implementation with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are the embodiment of the present invention. Some, but not all, embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0027] Aiming at the problem that the display panel in the prior art can only realize the conventional touch function, the embodiment of the present invention provides a display panel, which can realize the pressure-sensitive touch function without adding additional pressure-sensitive touch device, and does not need to increase the thickness of the displa...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel comprises a substrate, a touch-control electrode layer, and a public electrode layer. The touch-control electrode layer comprises multiple touch-control electrode blocks distributed in an array. Touch-control electrode blocks comprise first touch-control electrode blocks and second touch-control electrode blocks. The public electrode layer runs opposite to the touch-control electrode layer and comprises multiple strips of public electrodes in stripped shapes. At least one public electrode is reused as a pressure reference electrode. One pressure reference electrode and at least one row of first touch-control electrode blocks are overlapped in the direction vertical to the substrate. The first touch-control electrode blocks are used for sensing pressure value of a plane vertical to the substrate. The second touch-control electrode blocks are used for sensing the touch-control position of the panel where the substrate is located. The display panel and the display device have following beneficial effects: the display panel is equipped with a pressure touch function by the public electrode layer and the touch-control electrode layer and can achieve the conventional touch-control function and a press touch function at the same time; compared with the prior art, the thickness of the display panel is kept unchanged and any additional press touch device is not needed.

Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular, to a display panel and a display device. Background technique [0002] Embedded touch screen (Embedded Touch Screen) is to manufacture touch components inside the liquid crystal panel, so that the touch screen has the advantages of thinner and lighter weight. [0003] Such as Figure 1A Shown is a plan view of an existing embedded touch panel, Figure 1B yes Figure 1A As shown in the sectional view along AA′, the in-cell touch panel includes an array substrate 10 and a color filter substrate 20 oppositely arranged. Specifically, the array substrate 10 is provided with a common electrode layer, and the common electrode layer includes planar common electrodes 11, and the color filter substrate 20 is provided with a touch electrode layer, and the touch electrode layer includes A plurality of touch electrode blocks 21 of cloth. In the existing in-cell touch panel, t...
