Abstract

The invention provides a touch panel and a display device. The touch panel comprises a transparent substrate, at least one light ray emitting unit, a sealing layer and at least one light ray receiving unit. The transparent substrate comprises a first surface and a second surface opposite to the first surface, the first surface and the second surface are used for conducting touching, and the substrate comprises a touch area located in the middle of the substrate and a non-touch area on the periphery of the substrate. The light ray emitting unit is arranged on the non-control area of the second surface and used for emitting light rays including infrared light towards the interior of the substrate. The sealing layer is arranged between the light ray emitting unit and the substrate and used for sealing a light ray outlet face of the light ray emitting unit, the part, away from the light ray outlet face of the light ray emitting unit, of the sealing layer is a plane, and thus light rays are totally reflected in the substrate. The light ray receiving unit is arranged on the non-touch area of the second surface and used for receiving the light rays which are emitted by the light ray emitting unit and pass through the substrate. The connecting line of the light ray emitting unit and the light ray receiving unit transversely penetrates through the touch area.

Description

technical field [0001] The invention relates to the technical field of touch recognition, in particular to a touch panel and a display device. Background technique [0002] Touch panel (English full name is Touch Panel), also known as touch screen and touch screen, is a device that is formed on the display surface of an image display device and uses conductors such as human body or capacitive pen to input commands. It can replace the mouse, keyboard, etc. Input devices such as external input devices and mechanical input keys can effectively simplify the structure of electronic products such as computers, mobile phones, electronic instruments, and game equipment, and have very broad application prospects. [0003] In terms of technical principles, touch panels can be divided into five types: vector pressure sensing touch panels, resistive touch panels, capacitive touch panels, infrared touch panels, and surface acoustic wave touch panels. Existing infrared touch panels such ...
