An infrared touch module and an infrared touch display device

Abstract

The invention discloses an infrared touch module, which comprises a circuit board, an infrared point light source, an optical lens and a casing. The infrared point light source is mounted on the circuit board. The upper and lower ends of the upper and lower ends are bent toward the middle of the frame structure to the first frame edge and the second frame edge; there is a groove running through the end face of the first frame edge in the housing, and the circuit board and the infrared point light source are accommodated in the groove, and the infrared The point light source faces the outlet of the groove; a slot for inserting the end of the display device is formed between the first frame side and the second frame side. The invention also discloses an infrared touch display device. The periphery of the display device is inserted into the slot of the infrared touch module and fixed relatively to the infrared touch module, which can ensure the reliability of the infrared touch module. At the same time, it avoids the use of various fixing structures for fixing, reducing structural parts The vertically installed circuit board in the infrared touch module is also conducive to the narrow frame design of the infrared touch display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an infrared touch module and an infrared touch display device. Background technique [0002] Infrared multi-touch (IRMT) technology is to detect and locate a person's touch gestures by using an infrared matrix densely distributed in the X and Y directions. The infrared touch screen is mainly to install the circuit board frame in front of the display. The receiving tubes correspond to each other on opposite sides of the screen, forming a horizontal and vertical infrared matrix. When the finger touches the screen, it will block the two infrared rays passing through the position, so the coordinate position of the touch point on the screen can be judged. The advantage of this kind of touch screen is that any non-transparent object can change the position on the touch point. Infrared to achieve touch screen operation.

AI Technical Summary

Problems solved by technology

[0003] In the current commercial display market, display screens generally require touch functions in end-customer applications. Ordinary display screens usually use touch screens with infrared technology. However, since the infrared touch structure is usually integrated and fixed to the display as a separate module On the screen, the display screen cannot guarantee the reliability of the connection of the infrared touch structure. In order to make up for this defect, many auxiliary reinforcements are often used to fix between the display screen and the infrared touch structure, but this also directly increases the structural reliability. Complexity, overall aesthetics, and cost of the product
