Problems solved by technology

[0003] like figure 1 As shown, a plurality of block-shaped transparent conductive films 11-14 are distributed above the via hole 15, and usually the via hole 15 partially overlaps with at least one of two adjacent block-shaped transparent conductive films in the longitudinal direction, so that in During the film forming process of the transparent conductive film, it is easy to adhere to the via hole 15, and the transparent conductive film in the via hole 15 is difficult to remove through the etching process, resulting in electrical connection between two adjacent transparent conductive films, which is prone to short circuit, making Display Error

Abstract

The invention provides a touch panel and a touch display panel. The touch panel comprises a substrate, a plurality of touch units and a plurality of via holes, wherein the touch units are arranged at intervals and are used for receiving touch commands of users and generating touch signals; and the via holes are formed in the substrate and below preset areas, each preset area is a clearance area between every two adjacent touch units, each via hole corresponds to two of the touch units, and the projections of the via holes on the substrate are not overlapped with the projections of the corresponding touch units on the substrate. According to the touch panel and the touch display panel, every two adjacent touch units are prevented from short circuit.

Description

【Technical Field】 [0001] The present invention relates to the technical field of displays, in particular to a touch panel and a touch display panel. 【Background technique】 [0002] In the field of touch display, a transparent conductive film is generally used to sense the touch of a finger. The transparent conductive film is distributed in blocks, and the blocks are distributed at intervals. Via holes are often provided in the gaps of the bulk transparent conductive film, and the via holes are used to connect other functional layers other than the bulk transparent conductive film to ensure normal display. [0003] Such as figure 1 As shown, a plurality of block-shaped transparent conductive films 11-14 are distributed above the via hole 15. Generally, the via hole 15 is at least partially overlapped with one of the two adjacent block-shaped transparent conductive films in the longitudinal direction, so that During the film forming process of the transparent conductive film, it is...
