Problems solved by technology

[0003] However, under normal circumstances, a touch panel includes a lot of touch electrodes, since each touch electrode needs a lead pin and a signal output line, which leads to more leads at the steps where the touch panel is connected to the signal source , and there are more lead pins

Abstract

The present invention provides a touch panel, which includes a substrate, a touch electrode layer and a plurality of touch traces are arranged on the substrate, the touch electrode layer includes a plurality of mutually insulated touch electrodes, Each of the touch electrodes is connected to a first end of a corresponding touch wire, and the touch panel further includes: a multiplex gate circuit, and the multiplex gate circuit includes: a plurality of touch screens A switch, and at least one touch clock signal line; wherein, each of the touch switches includes a control terminal, a signal input terminal, and a signal output terminal, and the signal output terminal is connected to the second terminal of the corresponding touch wiring. The signal input terminals of at least two touch switches are electrically connected to each other and to a touch signal source, and the control terminal of each touch switch is connected to the corresponding touch clock signal line. Compared with the prior art, the touch panel provided by the present invention reduces at least one signal output line and at least one lead pin, so the touch panel provided by the present invention reduces the number of leads and pins. The invention also provides a touch display panel and a display device.

Description

technical field [0001] The present invention relates to the field of liquid crystal technology, in particular to a touch panel, a touch display panel and a display device including the touch panel. Background technique [0002] The touch panel in the prior art includes a touch electrode layer. The touch electrode layer includes a plurality of mutually insulated touch electrodes. Each touch electrode requires a touch trace, and each touch trace requires Connect with a signal output line drawn from the touch signal source and a lead pin, so that the touch signal source can input the output touch detection signal to each touch trace. [0003] However, under normal circumstances, a touch panel includes many touch electrodes. Since each touch electrode requires a lead pin and a signal output line, this leads to more leads at the steps where the touch panel is connected to the signal source. , and there are more lead pins. Contents of the invention [0004] In view of this, in...
