Description

Touch panel device, circuit pin attribute programmable integrated circuit and programmatic method thereof

The present invention relates to an integrated circuit and a stylized method thereof, and a touch panel device, and more particularly to a programmable method for a circuit pin attribute programmable circuit and a control circuit pin attribute; and the foregoing integrated circuit Touch panel device.

FIG. 1A shows a schematic diagram of a conventional capacitive touch panel. FIG. 1B shows a schematic diagram of a conventional capacitive touch panel and an integrated circuit (IC). Referring to FIG. 1A and FIG. 1B , a capacitive touch panel 110 is coupled to an integrated circuit 120 through a circuit layout 130 .

The capacitive touch panel 110 includes a plurality of electrode lines, the electrode lines include Xn+Ym electrode lines, each electrode line Xn includes a plurality of electrodes 113, and each electrode line Ym includes a plurality of electrodes 112. In the conventional example of FIG. 1B, n is 1 to 8, and m is 1 to 8 as an example, and for the convenience of description, only a simple schematic diagram is shown in FIG. 1B. As shown in FIG. 1B, the electrode lines X1 to X8 extend vertically and the electrode lines Y1 to Y8 extend horizontally. Depending on the product design, the electrode lines X1~X8 and the electrode lines Y1~Y8 correspond to different properties. For example, the electrode lines X1~X8 receive pulse signals and correspond to the driving states D0~D7, respectively. The electrode lines Y1~Y8 detect the pulse signal to sense a contact state, and output a detection signal, and respectively correspond to the sensing states S0~S7.

The integrated circuit 120 includes a plurality of pins (PIN), the pins including pins T0 to T7 for outputting a pulse signal, and pins R0 to R7 for detecting a pulse signal. The pin positions T0~T7 correspond to the driving states D0~D7, respectively, and the pin positions R0~R7 correspond to the sensing states S0~S7, respectively.

As described above, the channel of the capacitive touch panel 110 can be divided into a sensing state (Sensing) and a driving state (Driving). Sometimes, because the arrangement of the electrode lines designed by different manufacturers is different, it is necessary to redesign and customize the arrangement of the IC pins of the integrated circuit 120 for the arrangement of the electrode lines. . Or use a printed circuit (PCB) transfer board to switch the circuit.

FIG. 2 shows a schematic diagram of another conventional capacitive touch panel and an integrated circuit (IC). As shown in FIG. 2, the conventional architecture further includes at least one PCB flap 141 and 142. The PCB transfer plate 141 is coupled between the electrode lines X1 to X8 and the pin positions T0 to T7. The PCB rotation plate 142 is coupled between the electrode lines Y1 to Y8 and the pin positions R0 to R7. The PCB transfer plates 141 and 142 reconfigure the circuit layout so that the arrangement of the pins of the integrated circuit 120 can match the arrangement of the electrode lines of the capacitive touch panel 110, so that the IC of the integrated integrated circuit 120 is not required.

Since the coordinate arrangement of the capacitive touch panel 110 is determined in the panel design, if the position of each integrated circuit 120 is changed, the position of the integrated circuit 120 and the capacitive touch panel are made. When the electrode lines of 110 do not cooperate with each other, the control operation of the integrated circuit 120 must be replaced, and the calculation cannot be directly performed, thereby increasing the coordinate calculation time.

In addition, the arrangement of the positions of the capacitive touch panel 110 cannot be arranged according to the position of the capacitive touch panel 110 due to the Layout convenience and impedance considerations. Connecting the electrode wires must be solved by the circuit layout of the printed circuit board, but too complicated wiring can affect the capacitive sensing characteristics.
