The invention provides a touch panel and a display device. The touch panel comprises a transparent substrate, at least one light emitting unit, a scattering layer and at least one light receiving unit, wherein the transparent substrate comprises a first surface for touching and a second surface opposite to the first surface; the at least one light emitting unit is arranged on a non-touch region of the second surface and used for emitting the light comprising infrared light facing to the internal part of the substrate, and the emission surface of the light emitting unit is a plane; the scattering layer covers the light emission surface of the light emitting unit and is used for coupling the light emitted by the light emitting unit into the substrate, so that the light is fully reflected in the substrate; scattering particles are contained in the scattering layer; the at least one light receiving unit is arranged on the non-touch region of the second surface and is used for receiving the light transmitted by the light emitting unit and passing through the substrate; the connecting line between the at least one light emitting unit and the at least one light receiving unit crosses the touch region.
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 ...
