Problems solved by technology

[0004] In the existing technology, due to the limitation of the manufacturing process, it is difficult to process smaller-sized infrared light-emitting diodes. Therefore, the physical resolution of infrared touch is limited. control application needs
On the other hand, as the demand for large-size touch screen applications increases, in order to ensure the physical resolution of the touch, the infrared grid matrix requires more and more infrared transceivers. It is inevitable to install a large number of infrared transceivers. increase the manufacturing cost of the display device and increase the energy consumption of the product, these problems cannot be solved by the existing technology

Abstract

The embodiment of the invention provides a touch panel, a touch-type display device and a touch method, which relates to the field of the manufacturing of a display device, can enable the physical resolution of the touch panel to be free from the limitation of the arrangement number of infrared receiving and transmitting devices, improve the physical resolution of the touch panel, reduce the quantity of the infrared receiving and transmitting devices and reduce the production cost and energy consumption of the display device. The touch panel comprises an infrared transmitting device and a first light guide module, which are arranged on one end of the panel, and / or an infrared receiving device and a second light guide device, which are arranged on the other end of the panel, wherein the first light guide module is used for splitting one path of infrared light transmitted by the infrared transmitting device into two or more paths of parallel infrared light; and the second light guide module is used for converging the more than two paths of parallel infrared light transmitted by the infrared transmitting device. The embodiment of the invention is used for manufacturing the touch panel.

Description

technical field [0001] The invention relates to the field of display device manufacturing, in particular to a touch panel, a touch display device and a touch method. Background technique [0002] With the continuous development of display technology, touch display devices have gradually attracted more and more people's attention due to their features such as convenient operation. Among various existing touch display devices, the infrared touch panel has been widely used due to its advantages of high stability and strong light transmission. [0003] The current infrared touch panels usually use infrared grids to realize the positioning of the user's touch position, which requires multiple sets of infrared transceivers to be installed on the left, right, up and down of the screen to form an infrared matrix. When the user performs a touch operation, the user's The finger will block the reception of infrared light at a specific position, and the precise positioning of the user'...
