Embodiment Construction

[0065] figure 1 It is a schematic diagram of a touch detection system according to an embodiment of the present invention. exist figure 1 In , the direction is defined in the XYZ Cartesian coordinate system. The infrared touch detection system of the present invention is as figure 1 Shown includes a touch substrate 1 and at least one infrared sensor array 2 .

[0066] The touch substrate 1 is an interface for user touch input, and is generally rectangular with four sides parallel to the X direction or the Y direction. The touch substrate 1 can be glass or other transparent materials, and the touch substrate 1 is not limited to a rectangle.

[0067] The infrared sensor array 2 is arranged along the four sides of the touch substrate 1 and extends in the normal direction (set as the Z direction). The length in the Z direction) is 0.1 mm to 1 mm, forming a wall-like structure surrounding the touch substrate. However, the infrared sensor array of the present invention actuall...

Abstract

The invention provides a touch control detection system. The touch control detection system comprises a touch control substrate and a first infrared ray sensor array, wherein the touch control substrate is provided with an upper surface, and a detection area is defined in the upper surface; the first infrared ray sensor array is arranged on the upper surface of the touch control substrate and located on the first side outside the detection area. The invention further provides a touch control detection method. In this way, the infrared ray sensing array is arranged on the outer side of the detection area, so the number of stack-up structures within the detection area is reduced; therefore, the problems that as an existing touch control panel is provided with the multilayer stack-up structures, transmitted light is not uniform, and color distortion is caused can be solved.

Description

technical field [0001] The present invention relates to a touch technology, and in particular to a touch detection system and a touch detection method. Background technique [0002] Because the touch panel can be applied to portable products and has the advantages of user-friendly operation, it is helpful to be widely used in various electronic products, including personal digital assistants (personal digital assistant, PDA), palm sized computers (palm sized PC), mobile phone, handwriting input device, information appliance (Information appliance), automated teller machine (automated teller machine, ATM), and store sales teller machine (point of sale, POS), etc. The number of portable communication and consumer electronics products is increasing day by day, and these products will use touch panels as their input devices in large numbers. Therefore, many companies have invested in the development of technologies related to touch panels in recent years. [0003] Common touch ...
