Abstract

The invention discloses a touch display device and a method thereof. The touch display device comprises a display panel, an infrared detection device, a signal processor and a controller, wherein the infrared detection device is arranged around the display panel, and is used for detecting a touch signal produced by an object touching the display panel, and providing the touch signal for the signal processor; the signal processor is electrically connected with the infrared detection device and the controller, and is used for processing the touch signal provided for the infrared detection device, so as to obtain touch information, such as touch point type information and gesture type information; according to the touch information, a touch point or gesture type touch instruction is generated, and is provided for the controller; the controller is electrically connected with the display panel, and is used for making response to the touch instruction, and controlling the display panel to correspondingly display. The touch display device and the method have the advantages that the touch operation is rapidly realized, the touch structure is simple, and the cost is lower.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a touch display device and a method thereof. Background technique [0002] With the popularization of display devices, keyboards, mice, remote controllers, etc. have become the most acceptable information input devices for the general public. However, due to the shortcomings of the keyboard, mouse, etc., which are large in size and not easy to carry, and are slightly complicated in input, and cannot allow users to experience the convenience and enjoyment brought by touch, in recent years, with the development of society and the advancement of technology, there have been Touch display technology. Moreover, the display device with a touch panel with a more humanized interface and easier input is also widely used in display devices such as personal computers, mobile phones, televisions, cameras, and measuring instruments. A display device with a touch panel generally includ...
