Problems solved by technology

Because the pins S0˜S21 of the conventional sensing controller 130 must be connected to the wires Y0˜Y11 and X0˜X9 of the sensing lines of the capacitive touch panel 110 in a specific order, the printed circuit board 120 Corresponding changes must also be made to the layout of the wires above and the layout of the parts of the wires Y0-Y11 and X0-X9 outside the sensing area A1, so as to be properly connected to the corresponding pins of the sensing controller 130 respectively. However, The inflexible connection between the capacitors of the capacitive touch panels 110a and 110b and the pins of the sensing controller 130 will make the layout of the wires more complicated and difficult.

Embodiment Construction

[0067] figure 2 A functional block diagram of a touch panel device according to an embodiment of the present invention is shown. image 3 A schematic diagram showing the structure of a touch panel according to an embodiment of the present invention. Please refer to figure 2 and image 3 , the touch panel device 200 includes a touch panel 210 ; and a sensing control device 220 coupled to the touch panel 210 . The touch panel 210 includes a plurality of sensing lines, the sensing control device 220 includes a plurality of pins S0 - S15 , and the pins S0 - S15 are respectively coupled to the sensing lines. The sensing control device 220 controls the sequence of scanning the pins S0 - S15 according to the connection relationship between the pins S0 - S15 and the sensing lines. Therefore, the pins S0-S15 do not need to be coupled to the sensing lines of the touch panel 210 in a specific order, but can be coupled to the sensing lines in any order, whereby the touch panel 210 and...
