Problems solved by technology

[0003] It can be seen from the above that whether it is wireless charging technology or short-distance wireless communication, the wire is wound into a coil as an induction antenna, which is realized by the principle of electromagnetic induction. However, the induction antenna in the existing display panel is usually located in the frame area of ​​the display panel , although the volume of the display panel can be reduced, but limited by the area of ​​the frame area, the number of turns of the coil is small, resulting in low conversion efficiency

Abstract

A display panel and a display device including the display panel are provided. The display panel includes data lines and scan lines arranged to be intersected, and a sensing antenna. The data lines and the scan lines are located in a display region of the display panel, and define multiple sub-pixels. The sensing antenna includes multiple sensing coils and is at least partly located in the display region of the display panel, and projections of the data lines and / or the scan lines cover projections of the sensing coils in a direction perpendicular to a surface of the display panel, in order to avoid affection on an aperture ratio of the display panel caused by the sensing coils located in the display region.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. Background technique [0002] With the development of science and technology, wireless charging technology and Near Field Communication (NFC) are more and more applied to display panels. Among them, the wireless charging technology uses the wire to be wound into a coil, and through the principle of electromagnetic induction, the power transmitting side and the power receiving side are induced to realize charging; the short-distance wireless communication uses the principle of electromagnetic induction to make the signal transmitting end and the receiving end sense, It has a great effect on card swiping and data transfer. [0003] It can be seen from the above that whether it is wireless charging technology or short-distance wireless communication, the wire is wound into a coil as an induction antenna, which is realized by the princi...
