Abstract

The invention discloses a capacitive touch screen, a touch positioning method thereof and a display device. The capacitive touch screen comprises a first substrate and a second substrate which are oppositely arranged, wherein a black matrix is arranged on one side of the first substrate; since the black matrix consists of a metallic first touch electrode layer on the side, opposite to the second substrate, of the first substrate and a metallic second touch electrode layer on the side, facing to the second substrate, of the first substrate, wherein the first touch electrode layer comprises a plurality of first touch electrode wires and the second touch electrode layer comprises a plurality of second touch electrode wires crossly arranged with the first touch electrode wires, not only can the first touch electrode layer and the second touch electrode layer be used as the black matrix to play a role of screening light, but also the first touch electrode wires in the first touch electrode layer and the second touch electrode wires in the second touch electrode layer can be used as touch electrodes to realize a touch function. Compared with the structure of the existing capacitive touch screen, the overall thickness thereof can be reduced.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a capacitive touch screen, a touch positioning method thereof and a display device. Background technique [0002] According to the composition and structure, the touch screen can be divided into: Add on Mode Touch Panel, On Cell Touch Panel, and In Cell Touch Panel. Among them, the surface-covered touch screen is to arrange the touch electrodes of the touch screen between the opposite substrate and the polarizer of the display screen, which has a high yield and does not reduce the area of ​​the display area; The touch electrodes are arranged inside the display screen, which can reduce the overall thickness of the module and reduce the production cost of the touch screen. [0003] At present, for a capacitive touch screen that combines a surface-covered touch screen and an embedded touch screen, taking a liquid crystal display as an example, touch scanning lines and touch sensin...
