Abstract

The embodiment of the invention provides a touch panel and a touch device, the touch panel comprises a touch area and a frame area, and the touch area comprises a plurality of emission channels. The frame area is arranged on the edge of the touch area. The frame area comprises a plurality of first wires, a plurality of second wires and a plurality of conductive thin film layers arranged at intervals, and each conductive thin film layer is connected with one first wire and one second wire so that the corresponding first wire and the second wire can be connected in parallel. And the first wire and the second wire which are connected in parallel are connected with one emission channel. According to the embodiment of the invention, the first wire and the second wire which are connected in parallel are arranged at the wire end of each emission channel, so that the wire impedance of the frame area in the touch panel can be reduced, the response speed of touch control is improved, and the touch control performance of the touch panel is improved.

Description

technical field [0001] The present application belongs to the field of touch technology, and in particular relates to a touch panel and a touch device. Background technique [0002] In metal grid touch, the impedance of the channel is mainly composed of two parts, one is the impedance of the in-plane channel, and the other is the trace impedance of the frame area. Among them, the wiring impedance in the frame area is the main impedance in the metal grid, and if the wiring impedance is too high, it will affect the response time of the touch control, resulting in a decrease in touch performance. Contents of the invention [0003] Embodiments of the present application provide a touch panel and a touch device, which can reduce the impedance of wiring in the frame area, improve the response speed of touch, and thus improve the touch performance. [0004] In the first aspect, the embodiment of the present application provides a touch panel, including: [0005] touch area, inc...
