Abstract: A security method for monitoring an optical module and a three-dimensional sensor using the same apply electromagnetic induction to the three-dimensional sensor to monitor the optical module and a light source module. Two inductive coils corresponding to each other are arranged on the light source module and the optical module. An alternative current is inputted to one of the inductive coils and another of the inductive coils generates an inductive current. The value of the inductive current is continuously detected. When the value of the inductive current varies, the abnormality of the optical module is determined to shut down the light source module, thereby completing the security mechanism of the three-dimensional sensor.

Abstract: A touch panel defines a touch area and a reduced border area surrounding the touch area. The touch panel includes a substrate, a first conductive layer on the substrate, an insulating layer on the substrate and covering the first conductive layer, and a second conductive layer on the insulating layer. The second conductive layer includes first electrodes and strings of second electrodes in the touch area, each string of second electrodes extending in a first direction. The first conductive layer is conductive but almost opaque. The first conductive layer includes a decorative portion in the border area and first bridge portions in the touch area. Each first bridge portion is electrically coupled between adjacent two first electrodes in a second direction that intersects with the first direction. The decorative portion is configured to release static electricity and shield the border area.

Abstract: The touch panel includes a transparent substrate, a first touch-sensing electrode structure, a second touch-sensing electrode structure, and a patterned metal layer. The transparent substrate has a touch-sensing region and a peripheral region adjacent to at least one edge of the touch-sensing region. The first touch-sensing electrode structure is disposed on the touch-sensing region of the transparent substrate. The second touch-sensing electrode structure is positioned over the touch-sensing region and is configured to form at least one capacitor with the first touch-sensing electrode structure. The patterned metal layer has a plurality of first through holes located in the peripheral region and is extended on a level the same as the first touch-sensing electrode structure or the second touch-sensing electrode structure.
