Problems solved by technology

[0005] figure 1 and figure 2 In the infrared touch screen shown in , due to the small angle of the single infrared emission tube used, the area that can be covered is very limited. Only two infrared irradiation directions are inspected, and the infrared detection optical network that can be formed is relatively sparse. It can meet people's increasing demand for the use of infrared detection optical network density

Embodiment Construction

[0028] In order to better understand the present invention, the implementation manner of the invention will be described in detail below in conjunction with specific examples and accompanying drawings.

[0029] In order to solve problems such as the small irradiation angle of the infrared emission tube of the existing touch screen, the low density of the formed infrared detection optical network, and the easy interference of the touch screen, the present invention provides a full-plane infrared multi-touch device and its control method.

[0030] see image 3 and Figure 4 , which is a schematic diagram of the infrared detection optical network and a schematic diagram of the hardware framework of the full-plane infrared multi-touch device according to the first preferred embodiment of the present invention. exist image 3 , Figure 4 In the infrared multi-touch device shown, it contains six infrared emission tubes IR1, IR2, IR3, IR4, IR5 and IR6, wherein the infrared emissi...

Abstract

The invention provides a flat face infrared multi touch device and control method of the flat face infrared multi touch device. An infrared transmitting module comprises at least three infrared transmitting tubes, the infrared transmitting tubes are arranged on at least two corners and at least one side of a touch region, an infrared receiving module comprises a plurality of infrared receiving heads, and the infrared receiving heads are evenly arranged on the four sides of the touch region. The invention further provides a method for controlling the flat face infrared multi touch device. By adopting the technical scheme of ' the infrared transmitting tubes are arranged on at least two corners and at least one side of the touch region' to arrange the infrared transmitting tubes, the infrared transmitting tubes are arranged on the corners of the touch region, infrared detection optical network generated by the infrared transmitting tubes is distributed in the whole touch region, the infrared transmitting tubes are additionally arranged on the sides of the touch region, and therefore density of the infrared detection optical network in the middle of the touch region is offset, and the infrared detection optical network with high density in the touch region can be acquired.

Description

【Technical field】 [0001] The invention relates to the field of infrared touch control, in particular to a full-plane infrared multi-touch device and a control method thereof. 【Background technique】 [0002] With the release of Microsoft's Win7 and Win8 operating systems and the launch of Apple's iPhone, the application of large touch screens has begun to rise. Existing touch screen types can be classified into resistive (double layer), surface capacitive and inductive capacitive, surface acoustic wave, infrared and optical imaging according to the touch principle. [0003] Infrared touch screens generally install an outer frame in front of the display screen, and a circuit board is installed inside the outer frame. Infrared emitting tubes are installed on the left (Y axis) and lower (X axis) of the front frame of the screen, respectively. The respective opposite sides are equipped with corresponding infrared receiving diodes, such as figure 1 shown in . When working, a cr...
