Abstract

A touch screen realized based on a total reflection wave technology comprises a transparent touch substrate, a first light guiding device, a touch control light source, a second light guiding device and a light receiver, wherein the touch substrate comprises an upper surface and a lower surface opposite to the upper surface in parallel; the upper surface is a touch surface; the first light guiding device is arranged below the lower surface of the touch substrate; the touch control light source is arranged below the lower surface of the touch substrate and close to the first light guiding device; the second light guiding device is arranged below the lower surface of the touch substrate; the light receiver is arranged below the lower surface of the touch substrate; the light receiver and the touch control light source are located below the two opposite sides of the touch substrate respectively; the light receiver right faces the second light guiding device; the touch control light source right faces the first light guiding device. The touch screen has the advantages that touch suspension height does not exist, the capacity of resisting intense light interference is high, no wider and higher edge protrusion exist, and narrow edge design is facilitated. The invention further provides a touch display device with the touch screen.

Description

【Technical field】 [0001] The invention relates to a touch screen, in particular to a touch screen realized based on total reflection light wave technology and a touch display device using the touch screen. 【Background technique】 [0002] The existing infrared touch system adopts the method of driving the infrared emitting tube and the infrared receiving tube under the control of the control and driving circuit by installing uniformly arranged infrared emitting tubes and infrared receiving tubes in the X and Y directions around the touch area. The receiving tube is correspondingly scanned to form an infrared matrix that crosses horizontally and vertically in the X direction and the Y direction. When there is a touch, fingers or other objects will block the horizontal and vertical infrared rays passing through the point, and the control system can judge the position of the touch point on the touch screen. [0003] At present, in the field of infrared touch screen, for example...
