Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a button system, especially to a touch button system having externally programmable display.

2. Description of the Related Art

Please refer to FIG. 1a, which illustrates an outline of a button with display of prior art; and FIG. 1b, which illustrates a block diagram of the internal circuit of the button with display of prior art. As illustrated in FIG. 1a, the button with display of prior art includes a mechanical button 10 and a display 20, and as illustrated in FIG. 1b, the internal circuit includes a micro controller 11, a display controller 12, and a serial peripheral interface (SPI) 13.

The display controller 12 drives the display 20 to display a user interface according to pre-stored display data. When the button with display of prior art is pressed, the micro controller 11 can provide detected information to an external device via the SPI 13.

However, when the number of mechanical connections of the mechanical button increases, the reliability of the button with display of prior art will decrease. Besides, when the user interface is to be changed, the button with display will need to connect and communicate with a program development kit to reload display data of another user interface, which causes much inconvenience.

To solve the foregoing problems, a novel button system is needed.

The control unit 110 includes at least one touch display interface 111, at least one input interface 112, and at least one output interface 113, wherein, the at least one touch display interface 111 is coupled with the display data input interface 103 and the button operation data output interface 102 of the at least one touch display button 100 for transmitting display data D_DIS1-D_DISM to and deriving button operation data D_BTN1-D_BTNM from each of the at least one touch display button 100; the at least one input interface 112 is used for receiving image data D_IMG1-D_IMGN from an external device, and the control unit 110 generates the display data D_DIS1-D_DISM according to the image data D_IMG1-D_IMGN; and the at least one output interface 113 is used for outputting at least one operation code D_COD1-D_CODEN, the at least one operation code D_CODE1-D_CODEN being generated according to the button operation data D_BTN1-D_BTNM. The image data D_IMG1-D_IMGN can be for displaying characters, symbols, figures, or images. When the image data D_IMG1-D_IMGN are for displaying images, an operator can see a real time image of a monitored scene on a touch display area.

The operation code D_CODE1-D_CODEN can include at least one identification code for at least one of the at least one touch display button 100, or a control code generated according to a hybrid operation. The operation code D_CODE1-D_CODEN can carry information of a touch operation, a dialing operation (where a user performs a gesture operation on a touch plane or rotates a band switch), or a press operation (where a user presses a pushbutton switch or a rocker switch) on at least one of the at least one touch display button 100. The hybrid operation can be a combination of a touch operation and a press operation, a combination of a touch operation and a dialing operation, or a combination of a touch operation, a dialing operation, and a press operation.

The central processing unit 120 is coupled with the at least one input interface 112 and the at least one output interface 113 of the control unit 110 to provide the image data D_IMG1-D_IMGN and receive the at least one operation code D_CODE1-D_CODEN, and drive at least one object 200 in response to the at least one operation code D_CODE1-D_CODEN.
