The thicknesses and shapes of the various layers of film in the drawings are not to scale relative to the true touch screen and are intended to be illustrative of the invention.
As shown in fig. 2a to 2c, a touch screen provided in an embodiment of the present invention includes: a substrate 100 having a display region S1 and a peripheral region S2, the peripheral region S2 including: a black matrix layer 110 on one side of the substrate base plate 100; the display area S1 includes: the first electrodes 120 and the second electrodes 130 are disposed on one side of the substrate 100 having the black matrix layer 110 and are disposed on the same layer, and each of the first electrodes 120 and each of the second electrodes 130 are disposed in an intersecting manner and are insulated from each other, wherein the first electrodes 120 include a plurality of sub-electrodes 121 independent from each other, and two adjacent sub-electrodes 121 belonging to the same first electrode 120 are electrically connected through a bridge line 140; the display area S1 further includes: the bottom portion 150 is used for shielding the bridge lines 140, and the bottom portion 150 and the black matrix layer 110 are made of the same material.
According to the touch screen provided by the embodiment of the invention, the bottoming part is made of the same material as the black matrix layer, so that the additional process and cost for preparing the bottoming part are not required, the patterns of the black matrix layer and the bottoming part can be obtained at the same time only by deforming the composition pattern for preparing the original black matrix layer, and the material of the black matrix layer is a black material, and the reflectivity of the black matrix layer is generally less than 10%, so that compared with the prior art, the reflectivity of a bridge connection line area can be reduced, and the problem of etching residue can be avoided.
Specifically, in the touch screen provided by the embodiment of the present invention, the material of the black matrix layer is a black photosensitive resin material.
In a specific implementation, in the touch screen provided in the embodiment of the present invention, the display area further includes a plurality of pixel units, and an orthogonal projection of the bottom portion on the substrate may be located between orthogonal projections of two adjacent pixel units on the substrate.
