Abstract

The invention discloses a display device and electronic equipment. The display device comprises a substrate, a plurality of touch electrodes and a plurality of touch wires. The substrate is provided with a first end and a second end which are oppositely arranged. The number of the touch electrodes is multiple, and the multiple touch electrodes are arranged on the substrate in an array mode. The touch wires are arranged on the substrate, the touch electrodes and the touch wires are located on different layers, and the touch electrodes and the corresponding touch wires are connected through via holes. Part of the plurality of touch wires comprises a first branch line and a second branch line which are connected with each other, the first branch line extends to the corresponding touch electrode from the first end to the second end so as to be connected with the corresponding touch electrode, the second branch line is located in an area corresponding to the touch electrode connected with the second branch line, and the second branch line is used for adjusting the length of the touch control wire. According to the invention, short circuit among the plurality of touch wires corresponding to the plurality of touch electrodes in the same column can be avoided, so that the product yield is improved.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display device and electronic equipment. Background technique [0002] With the development of touch technology, electronic devices with touch function are widely used in people's life and work, and display panels with touch function have become a research hotspot in the field of display. The touch structure of the existing touch display panel includes an add-on touch structure, a touch on cell structure and a touch incell structure. [0003] Wherein, the on-panel touch structure and the in-plane touch structure can greatly reduce the overall thickness of the touch display panel. Existing on-panel touch structures and in-plane touch structures can be classified into self-capacitance and mutual-capacitance. In order to reduce the impedance difference between multiple touch traces, the touch traces in the self-capacitive touch control often adopt an equal-length desi...
