Light touch panel, light touch display screen and light touch display device

The invention provides a light touch panel, a light touch display screen and a light touch display device. The light touch panel comprises a substrate and light sensitive elements arranged on the substrate; the light sensitive elements are used for converting infrared touch light into a current signal so as to judge the touch position of the infrared touch light according to the current signal. According to the light touch panel, the infrared touch light is converted into the current signal by adopting the light sensitive elements, and therefore more accurate and sensitive judgment can be performed on the touch position of the infrared touch light by the light touch panel, and the light touch performance of the light touch panel is further promoted.
