Abstract
The present disclosure provides a touch screen and a pressure-sensitive touch method, and a display apparatus. In one embodiment, a touch screen includes: a touch sensing layer including a touch sensing area configured to sense touch information of a touch action; a pressure sensing layer including a pressure sensing area including a plurality of photosensitive devices therein, the pressure sensing area configured to sense pressure information of the touch action, the photosensitive devices being configured to receive optical signals from a light-emitting side of the touch screen and convert the optical signals into electrical signals; and a processor configured to process the electrical signals converted by the photosensitive devices and output corresponding pressure information, the pressure information at least comprising a pressure strength of the touch action.
