Abstract

A touch-control apparatus includes a touch-control unit, a sensing unit and an auxiliary voltage supplying unit. The touch-control unit has a touch-control substrate and at least one touch-control electrode layer, which is disposed on a surface of the touch-control substrate. The sensing unit is connected with the touch-control electrode layer of the touch-control unit and outputs a charging signal according to a power signal. The auxiliary voltage supplying unit outputs an auxiliary charging signal to a sensing conductive bar of the touch-control electrode layer, so that the sensing efficiency of the touch-control apparatus can be improved due to the auxiliary charging signal.

Description

technical field [0001] The present invention relates to a touch device, in particular to a touch device capable of improving sensing efficiency. Background technique [0002] With the increasing demand for multimedia information query, touch screens (Touch Screen) have been gradually adopted by users, and have replaced mouse and keyboard as input tools. This change is due to the fact that touch screens are relatively simple, user-friendly and space-saving input tools, and have been widely used in visitor guidance systems, automatic teller machines, handheld mobile phones, notebook computers, point-of-sale terminals and industrial control system, etc. [0003] Please refer to figure 1 , which shows a schematic diagram of a touch device in the prior art. The touch device 1 includes a touch unit 11 and a sensing unit 12 . The touch unit 11 includes a touch substrate 111, at least one touch electrode layer 112, an insulating layer 113 and an electrical shielding layer 114, t...
