US 9,542,055 B2 · Self-capacitive touch screen and display device

Abstract

A self-capacitive touch screen and a display device are disclosed. The self-capacitive touch screen includes a first substrate and a second substrate arranged opposite to each other. A conductive layer and a plurality of first touch electrodes are provided on the first substrate. The conductive layer includes a plurality of hollow areas distributed in a matrix. The first touch electrodes are in one-to-one correspondence with the hollow areas, and orthographic projections of the first touch electrodes on the first substrate are disposed in orthographic projections of the hollow areas on the first substrate. Second touch electrodes are formed in areas, which correspond to the conductive layer, on the second substrate. The second touch electrodes and the first touch electrodes are configured for the touch-control of the touch screen in the touch process.
