Abstract

The invention discloses a touch input device. The touch input device comprises a touch panel and a control unit, wherein the touch panel comprises a plurality of first type of touch buttons and at least one second type of touch button, and each second type of touch button is provided with second touch contacts with the same quantity as the first type of touch buttons; the control unit is also provided with connecting ports with the same quantity as the first type of touch buttons, and each connecting port is respectively connected with the corresponding second touch contact and the corresponding first type of touch button, so that the quantity of touch signals output by the touch input device exceeds that of the connecting ports of the control unit. The quantity of the touch buttons of the touch input device is not limited by the quantity of the connecting ports of the control unit, and the touch function of the touch input device can be expanded.

Description

technical field [0001] The present invention relates to an input device, and in particular to a touch input device. Background technique [0002] The application of the touch input device is quite extensive. The touch input device has been included in the early notebook computers, which can control the movement of the cursor or click on the image of the user interface, and the notebook computer can be operated without using a mouse. With the development of technology, the touch input device can also be applied to the touch panel. For example, the display screen of a digital camera, a tablet computer, and a smart phone all have a touch function. [0003] see figure 1 , which is a schematic structural diagram of an existing touch input device. The existing touch input device 1 includes a touch panel 10, a control unit 11 and a printed circuit board 12, the touch panel 10 is arranged on the printed circuit board 12, the touch panel 10 includes a plurality of touch buttons 101...
