Abstract
Embodiments of the present invention provide a display panel and a display device. The display panel includes: wires arranged in the same layer, a first electrode block and a second electrode block, in the second electrode, adjacent second electrode blocks are electrically connected to each other through a metal pattern, wherein the metal pattern includes a first metal trace line, the second metal wiring and the metal island, the first end of the first metal wiring is electrically connected to the metal island, and the second end of the first metal wiring is electrically connected to the first end of the second metal wiring. In the second electrode block adjacent to the two electrodes, the second end of the second metal trace is electrically connected to the metal island. Since the metal pattern is made of a metal material, and the resistance of the metal material is small, the metal pattern can be reduced. The impact of the pattern on the touch performance of the second electrode. Compared with the prior art, the metal pattern in the embodiment of the present invention can reduce the increased impedance between the two second electrode blocks, and has little influence on the touch signal. It is beneficial to improve the touch performance of the second electrode.
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] In the prior art, the touch layer of the display panel includes a plurality of touch electrodes, and the plurality of touch electrodes are arranged on the same layer, wherein the touch electrodes extending along the first direction and arranged along the second direction use indium oxide The first wires made of tin material are electrically connected to each other and extend along the second direction, and the touch electrodes arranged along the first direction are electrically connected to each other by bridge wires. [0003] The cross-bridge wiring is made of metal material, so the cross-bridge wiring is opaque. In order not to affect the light transmittance of the display panel, the cross-bridge wiring needs to be made into a thinner wiring. Since static electricity is easy to be generated in the pro...
