Problems solved by technology

This technology needs to form a detection network on the surface of the screen, which will form an infrared pair tube that is higher than the screen surface. Within the range of the infrared pair tube, it belongs to the touch range, and cannot perform long-distance user operation recognition. The function is similar to that of a capacitive touch screen.

Embodiment Construction

[0030] Embodiments of the present application provide a touch screen, a display panel, and a display device, which are used to realize an infrared touch function for remote user operation recognition, and have a simple manufacturing process and excellent product performance.

[0031] The touch screen provided by the embodiment of the present application includes a plurality of infrared sensors. The infrared sensor includes a source, a drain, and an active layer between the source and the drain. The source is used to receive a voltage signal from outside the infrared sensor. The drain is connected to the infrared integrated circuit, the active layer receives the infrared reflected by the user, absorbs the energy of the infrared to generate carrier transition, forms a conductive channel, and conducts the source and the drain, that is, the infrared sensor is turned on. The voltage signal is sent to the infrared integrated circuit, and the infrared integrated circuit recognizes the...

Abstract

The invention discloses a touch screen, a display panel and a display device. The touch screen, the display panel and the display device are used for achieving the infrared touch control function of identifying user operation remotely and are simple in manufacturing technology and excellent in product property. The touch screen comprises multiple infrared sensors, and the infrared sensors comprise source electrodes, drain electrodes and active layers located between the source electrodes and the drain electrodes, wherein the source electrodes are used for receiving external voltage signals, the drain electrodes are connected with an infrared integrated circuit, and the active layers are used for absorbing the infrared ray energy reflected by a user and generating current carrier transition, so that a conductive channel is formed, the source electrodes are conductively connected with the drain electrodes, the source electrodes send the voltage signals to the infrared integrated circuit, and the infrared integrated circuit identifies the operation actions of the user according to the received voltage signals.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a touch screen, a display panel, and a display device. Background technique [0002] The common structure of the existing infrared touch screen includes infrared emitting and receiving sensing elements installed on the outer frame of the touch screen, forming an infrared detection network on the surface of the screen. When any object is touched by this kind of touch screen, the Infrared rays are used to operate the touch screen. This technology needs to form a detection network on the surface of the screen, which will form an infrared tube higher than the surface of the screen. Within the range of the infrared tube, it belongs to the touch range, and cannot perform long-distance user operation recognition. The function is similar to that of a capacitive touch screen. Contents of the invention [0003] Embodiments of the present application provide a touch screen, a ...
