Abstract
Disclosed are a touch screen and a display device. In the touch screen, the first electromagnetic touch electrodes (210) and the capacitive touch sensing electrodes (110) are disposed in the same layer, the second electromagnetic touch electrodes (220) and the capacitive touch driving electrodes (120) are disposed in the same layer, such that it is possible to simplify layer structures of the touch screen to a great extent, thereby reducing the thickness of the entire touch screen, while guaranteeing electromagnetic touch effect and capacitive touch effect, and simplify the manufacturing process and in turn save the production costs of the entire touch screen.
