Abstract

The invention discloses an infrared touch device and method. The infrared touch device comprises a display module, at least two infrared image sensors, and a control processing module, wherein the infrared image sensors can receive infrared rays of human bodies, the sensing frequency of each infrared image sensor is larger than or equal to the refresh rate of the display module, and the angles of receiving the infrared rays by the infrared image sensors are larger than or equal to the included angle between the infrared image sensors and the two ends of the corresponding sides; and the control processing module is connected with the infrared image sensors and used for receiving image data information of the display module which is collected by the infrared image sensors to form touch images, and analyzing and processing the touch images so as to obtain the number and position information of touch points of the human body touch display module. According to the infrared touch device and method provided by the invention, the manufacturing cost of a touch display screen is reduced, so the touch display screen is thinned and miniaturized.

Description

technical field [0001] The invention relates to liquid crystal display touch technology, in particular to an infrared touch device and an infrared touch method. Background technique [0002] At present, touch screens are used in many electronic products, such as computer desktops, mobile phones, digital cameras, MP3 / MP4, notebooks, ATM machines and so on. Generally, the touch screen recognizes the touch and its position on the screen, analyzes and processes it, and then executes corresponding operations based on the touch and its position. [0003] The touch display screen generally includes a touch panel, a display panel, and a control processing system. The touch panel records touch events and sends touch signals to the control processing system. The control processing system processes the touch signals and executes corresponding actions on the display panel based on the touch signals. operate. Several touch technologies are known including: resistive touch, infrared tou...
