Problems solved by technology

However, with figure 2 For example, multiple touch panels 210 use the same four-corner coordinates (0, 0), (10, 0), (0, 10) and (10, 10), so when the touch points fall on two or more When multiple touch panels 210 are adjacent to the border, the control circuit 220 can easily misjudge the user's single-finger touch as multi-finger touch

Embodiment Construction

[0020] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] Please refer to image 3 , image 3 It is a schematic diagram of a touch device 300 according to an embodiment of the present invention. The touch device 300 includes a plurality of touch panels 310A to 310D and a control circuit 320 . The control circuit 320 is coupled to the plurality of touch panels 310 . In this embodiment, the definable coordinate range of each of the touch panels 310A to 310D is 30×30, and the coordinates processed by the control circuit 320 are as follows: image 3 As shown, its coordinate range covers all the touch panels 310A to 310D, where the coordinates of the four corners of the touch panel 310A are (0, 0), (30, 0), (0, 30) and (30, 30) respectively. , the coordinates of the four corners of the touch panel 310B are (31,0), (60,0), (31,30) and (60,30), respectively, and the coor...

Abstract

The invention discloses a touch device control method. A touch device comprises a plurality of touch panels and a control circuit coupled to the touch panels. Adjacent areas of the touch panels are defined by the control circuit, and touch points of the touch panels are judged according to touch signals of the touch panels. When the control circuit judges that at least two touch points are arranged in the adjacent areas and positioned on at least two touch panels respectively, the control circuit judges whether the distance between at least two touch positions is smaller than a default value or not. When the control circuit judges that the distance between the touch positions is smaller than the default value, the control circuit redefines new touch points according to coordinates of the touch points, the touch points are replaced, and signals corresponding to the new touch points are outputted.

Description

technical field [0001] The present invention relates to the field of touch technology, in particular to a control method of a touch device. Background technique [0002] Please refer to figure 1 , figure 1 It is a schematic diagram of the touch device 100 in the prior art. The touch device 100 includes a single touch panel 110 and a control circuit 120 . The control circuit 120 is coupled to the touch panel 110 . When the touch panel 110 is touched, the touch panel 110 will generate and output a corresponding touch signal to the control circuit 120 . The control circuit 120 then determines the touched position of the touch panel 110 according to the received touch signal. However, due to the limitations of equipment used to produce touch devices, figure 1 The architecture is not suitable for super-sized touch devices. [0003] Please refer to figure 2 , figure 2 It is a schematic diagram of another touch device 200 in the prior art. The touch device 200 includes ...
