A light touch panel, a light touch display screen and a light touch display device are disclosed. The light touch panel includes a substrate (1) and one or more light sensitive elements (2) disposed on the substrate, wherein the light sensitive elements (2) are configured to convert touch infrared light incident onto them into current signals to facilitate determining a touch position of the touch infrared light according to the electric current signals. The light touch panel converts touch infrared light that is incident onto it into current signals with light sensitive elements, thereby enabling the light touch panel to determine touch position of touch infrared light more accurately and sensitively, and in turn improve light touch performance of light touch panels.
