Abstract: A control method, suitable for a controller in an interface device having capacitive sensors, includes following steps. The capacitive sensors are arranged on a plane. During a first period, the controller is configured to set the capacitive sensors as self-capacitance sensors individually. During a second period, the controller is configured to divide the capacitive sensors into at least a first group and a second group, set the first group of capacitive sensors as a mutual-capacitance transmitter and generate a pulse signal to the mutual-capacitance transmitter, set the second group of capacitive sensors as a mutual-capacitance receiver and collect a sensing signal from the mutual-capacitance receiver in response to the pulse signal.

Abstract: A touch structure is provided. The touch structure includes a first sensing electrode, a second sensing electrode, a first dummy pattern and a second dummy pattern. The first sensing electrode and the second sensing electrode are arranged in a staggered manner and electrically insulated from each other. The first dummy pattern is adjacent to the first sensing electrode and has a first pattern acute angle. The second dummy pattern is adjacent to the second sensing electrode and has a second pattern acute angle. The first dummy pattern and the second dummy pattern are separated from each other. The first pattern acute angle and the second pattern acute angle are faced toward the same overlapped portion between the first sensing electrode and the second sensing electrode substantially.

Abstract: A touch display device including a drive chip and a touch display panel is provided. The drive chip includes a first common voltage source and a second common voltage source. The touch display panel includes a plurality of touch electrode including a plurality of rows and columns, wherein the number of columns is odd-numbered. The touch display panel includes a middle column, a first region and a second region. The middle column is interposed between the first region and the second region having the same number of touch electrodes. The touch electrodes in the first region and that in the second region are coupled to the first common voltage source and the second common voltage source respectively. The middle column is divided into a first half and a second half by a reference line. The first half and the second half have the same number of touch electrodes.

Abstract: A touch panel comprising a substrate, a plurality of first sensing electrodes, a plurality of second sensing electrodes, an insulating layer and a cover lens is provided. The first sensing electrodes are disposed on the substrate and are arranged in a first direction. The second sensing electrodes are disposed on the substrate and are arranged in a second direction. The first direction and the second directions are different. The insulating layer is disposed between the first and the second sensing electrodes. The cover lens is disposed on the insulating layer and has a non-uniform thickness. At least one of the surface areas of the first and the second sensing electrodes is related to the non-uniform thickness of the cover lens.
