Problems solved by technology

In actual use, it is found that there are the following problems in the touch layer: too many traces, which will cause the traces to occupy too much area, reduce the mutual capacitance, reduce the sensitivity, and too many traces will also cause the size of the bound FPC to be too large. Increased material cost and process difficulty
However, due to the above-mentioned problems in the touch layer, display panels or display devices with touch functions also have problems such as excessive wiring, low touch sensitivity, high cost, and difficult production.

Abstract

The invention provides a touch layer, a touch panel, a touch device, a display panel and a display device. The touch layer comprises a plurality of electrode arrays. Each electrode array comprises a first electrode set, a second electrode set and a third electrode set, wherein the first electrode set, the second electrode set and the third electrode set are sequentially arranged in the first direction. Each first electrode set comprises a plurality of first electrodes arranged in the second direction. Each third electrode set comprises a plurality of third electrodes arranged in the second direction. Each second electrode set comprises K second electrodes arranged in the second direction, wherein K is a positive integer greater than or equal to 2. In each second electrode set, each second electrode is electrically connected with a first wire, and the first wires are insulated from one another, wherein M first wires are led out of the first end of the corresponding electrode array, N first wires are led out of the second end of the corresponding electrode array, M and N are positive integers, and M plus N equals K. The touch layer can increase the signal to noise ratio of a touch signal.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch layer, a touch panel, a touch device, a display panel and a display device. Background technique [0002] Touch technology is becoming more and more popular at present. The touch device includes a touch panel, and a touch layer is usually formed on the touch panel. In actual use, it is found that there are the following problems in the touch layer: too many traces, which will cause the traces to occupy too much area, reduce the mutual capacitance, reduce the sensitivity, and too many traces will also cause the size of the bound FPC to be too large. Increased material cost and process difficulty. [0003] The combination of display technology and touch technology is a popular cross technology nowadays, which can form a display panel or display device with touch function. However, due to the above-mentioned problems in the touch layer, the display panel or display ...
