Abstract: A touch apparatus including a control button and a touch panel is provided. The control button includes an insulating main body and a conductive member disposed on the insulating main body. The touch panel is disposed on a side of the control button, and the touch panel includes a cover plate and a touch-sensing element. The conductive member is located between the insulating main body and the cover plate. The cover plate is located between the control button and the touch-sensing element. The touch-sensing element is electrically insulated from the conductive member. The touch-sensing element includes a plurality of electrodes disposed corresponding to the control button. The conductive member moves along with the movement of the insulating main body, and the movement of the conductive member causes a capacitance change of at least one of the plurality of electrodes.

Abstract: A touch device and a touch signal processing method thereof are provided. A type of a touch tool is determined according to a ratio between an average of signal intensities of sub touch signals of touch units in a target region and a signal intensity of a sub touch signal of a touch unit having the maximum signal intensity, and the touch signal is sharpened according to the type of the touch tool, so as to avoid interruption of the touch signal and misjudgment of a touch position due to inadequate intensity of sensing signals of the touch tool.

Abstract: An in-cell touch panel includes a transparent substrate having a first surface, a plurality of drive-end traces and a plurality of receive-end traces disposed on the first surface of the transparent substrate, and a plurality of color photoresists. The drive-end traces and the receive-end traces are utilized as a black matrix for defining a plurality of pixel regions. The color photoresists are disposed on the first surface of the transparent substrate and disposed in the pixel regions respectively.
