Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application.

[0029] figure 1 Shown is a schematic structural diagram of a top view angle of a touch panel provided by an embodiment of the present application. Such as figure 1 As shown, the touch panel provided by the embodiment of the present application has a touch area, and the touch panel includes: two first-type electrode layers stacked, for example figure 1 One layer of the first-type electrode layer 1 (ie, the first-type electrode layer 1 in (a)) and another layer of the first-type electrode layer 2 (ie, the first-type electrode layer 2 in (b)). Each of the first type electrode layer 1 and the first type electrode layer 2 includes a first type touch sensing area. The first-type touch sensing areas ...

Abstract

The invention provides a touch panel and a touch display device. The touch panel is provided with a touch area; the touch panel comprises at least two first type electrode layers which are arranged in a stacked mode; each first type electrode layer comprises a first type touch induction area; the first type touch induction areas included in the at least two first type electrode layers are spliced to fill the touch area; each first type of touch induction area comprises a plurality of first type of electrodes extending along a first direction; each first type electrode layer further comprises a first peripheral circuit area adjacent to the touch area, the first peripheral circuit area comprises a plurality of first signal leads, one ends of the first signal leads are electrically connected with the first type electrodes, and the first signal leads are distributed on at least one side of the first peripheral circuit area. According to the touch panel and touch display device of the embodiment of the invention, one type of electrodes are arranged on different layers, so that the number of signal leads corresponding to each layer of electrodes is reduced, and the edge width of the whole touch panel is further reduced.

Description

technical field [0001] The present application relates to the field of touch technology, in particular to a touch panel and a touch display device. Background technique [0002] Usually, a plurality of signal leads need to be arranged on the edge of the touch panel to ensure that the electrodes in the touch circuit are electrically connected to other electronic components. However, the provided signal leads will cause a problem that the peripheral wiring area of ​​the touch panel occupies a large side width. Contents of the invention [0003] In view of this, the embodiment of the present application provides a touch panel and a touch display device, which can reduce the width of the peripheral circuit area. [0004] In a first aspect, the present application provides a touch panel, the touch panel has a touch area, and the touch panel includes at least two first-type electrode layers stacked, the first-type electrode layer includes a first-type touch Control sensing are...
