Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0037]As mentioned in the background, existing display devices generally have the problem of low touch sampling rate, which affects the touch performance of the display device. After a long period of research, the inventors have found that the reasons for the above problems are as follows: the touch sampling rate of the display device usually represents the rate at which the driver chip acquires touch signals. Generally, the lower the touch sampling rate is, the slower the user will perceive the operation of the d...

Abstract

The embodiment of the invention discloses a display panel and a display device. The display panel includes: a substrate; a display function layer including a first electrode layer; a touch layer which is located on the side, away from the substrate, of the display function layer and comprises a plurality of emitting electrodes extending in the first direction and a plurality of receiving electrodes extending in the second direction, wherein the first direction intersects with the second direction, each transmitting electrode comprises a plurality of transmitting electrode blocks, and each receiving electrode comprises a plurality of receiving electrode blocks, each of the transmitting electrode block and the receiving electrode block comprises an electrode part, at least one of the transmitting electrode block and the receiving electrode block comprises a hollow part defined by the electrode parts, and the area of the hollow part accounts for 15%-30% of the sum of the area of one receiving electrode block and the area of one transmitting electrode block. Compared with the prior art, according to the technical scheme, the capacitive load formed by coupling of the touch electrodes and the first electrode layer can be reduced, the touch sampling rate of the display panel can be increased, and the touch performance of the display panel can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] In order to better meet user needs and improve user experience, smart display devices are developing toward high display refresh rates and high touch sampling rates. The touch sampling rate determines the speed at which the display device system responds to the user's touch operation. Currently, existing display devices generally have a problem of low touch sampling rate, which affects the touch performance of the display device. Contents of the invention [0003] Embodiments of the present invention provide a display panel and a display device, so as to reduce the load of touch electrodes and improve the touch performance of the display panel and the display device. [0004] In a first aspect, an embodiment of the present invention provides a display panel, including: [0005] Su...
