Problems solved by technology

At this time, the area covered by BM is increased, which is not conducive to realizing the narrow border of the touch display screen
[0004] If part of the structure of the touch electrode 5 on the edge covered by BM is removed, there will be a difference in electrical performance between the touch electrode 5 on the edge and the in-plane touch electrode, which will affect the o

Abstract

The invention relates to the technical field of touch control, and provides a touch screen and a touch display screen, the touch screen comprises a substrate, and the substrate is at least provided with a first surface. The touch screen at least comprises a first touch layer located on the first surface; the first touch layer comprises first touch electrode channels and first Dummy blocks which are arranged at intervals, and each first touch electrode channel comprises first edge sub-touch electrodes located on the two sides and first in-plane sub-touch electrodes located in the plane. The design of the metal grid lines of the first edge sub-touch electrodes is denser than that of the metal grid lines of the first in-plane sub-touch electrodes, and obvious optical difference can occur. An optical layer is arranged on the side, away from the first surface, of the first touch layer, the optical layer is provided with a prism structure at least in the projection coverage area of one edge sub touch electrode, and the prism structure can improve the visual consistency of the first edge sub touch electrode and the first in-plane sub touch electrode.

Description

technical field [0001] The present application relates to the field of touch technology, in particular to the field of touch display technology, and in particular to a touch screen and a touch display screen. Background technique [0002] At present, the touch display technology industry pays more and more attention to the design of the product frame, and strives to compress the frame of the touch screen (that is, the black frame) as much as possible while increasing the functional area and display area to obtain more market-competitive products. [0003] Such as figure 1 As shown, the current touch display screen includes a touch module 1 and a display module 2 bonded through an adhesive layer (not shown), and the size of the touch module 1 is slightly larger than that of the display module 2. size, the edge of the touch module 1 is covered by black shielding material 3 (BM) (mainly to shield the edge metal leads 4), so that the touch module is divided into a display area ...
