Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it, but the examples given are not intended to limit the present invention.

[0030] The core idea of ​​the present invention is that an infrared emitter line array is arranged on at least one side of the touch screen, an infrared receiver line array is arranged on at least the other side, and the infrared rays emitted by the infrared emitter line array are arranged on the reflectors arranged on the remaining sides. It forms an acute angle with the edge of the touch screen where the infrared emitter line array is located, so that at least a part of the infrared rays emitted by the infrared emitter line array are reflected by the reflector and reach the infrared receiver line array, and the infrared rays are interwoven into a network to realize touch detection...

Abstract

The invention discloses an infrared touch control device and a method. The infrared touch control device comprises an infrared emitter array arranged on a first edge of a touch screen, an infrared receiver array arranged on a second edge and a reflecting mirror arranged on remaining edges; infrared rays emitted by the infrared emitter array and the edge of the touch screen where the infrared emitter array is positioned form an acute angle. The infrared touch control device and the method have the benefits that the infrared emitter array and the infrared receiver array are only required to be arranged on the pair of opposite edges of a touch screen frame, and the reflecting mirror with small size is required to be arranged on the other two edges, therefore, the frame area occupied by a touch control element can be greatly reduced, so that the narrow frame is realized; meanwhile, through the infrared touch control device, the touch control resolution ratio can be improved by more than one time.

Description

technical field [0001] The present invention relates to the technical field of touch input, in particular to an infrared touch device and method. Background technique [0002] Touch input is used by more and more devices because of its advantages of intuitive operation, simplicity and convenience. Current mainstream touch technologies include resistive touch technology, capacitive touch technology and infrared touch technology. Infrared touch technology is often used for touch operations of large-size display devices, such as multimedia information inquiry machines, bank teller machines, and subway ticket machines. Infrared touch technology is also used on some small devices, such as the Kindle reader produced by Amazon that uses an electronic ink screen. [0003] Infrared touch technology is a densely distributed infrared emitting and receiving matrix in the X and Y directions close to the front of the screen, forming an infrared detection network on the surface of the sc...
