Embodiment Construction

[0037] Please refer to figure 1 and figure 2 As shown, they are a schematic diagram and a partially enlarged view of a mutual capacitance (MutualCapacitance) touch device according to the first embodiment of the present invention. The mutual capacitive touch device 100 of this embodiment is suitable for small and medium-sized touch devices, and has a multi-touch function. The mutual capacitive touch device 100 includes a plurality of first electrode pad series 110, a plurality of second electrode pad series 120, a plurality of first wires 131, 132, 133, 134, 135, 136, a plurality of second wires 141 , 142 , 143 , 144 , 145 , 146 and control unit 150 .

[0038] Each of the first electrode pad series 110 has a plurality of first electrode pads 111 , 112 , 113 , 114 and 115 . Wherein, the first electrode pads 111 , 112 , 113 , 114 and 115 have the same area, and the first electrode pads 111 , 112 , 113 , 114 and 115 of each first electrode pad series 110 are coupled in series...

Abstract

The invention discloses a mutual capacitive type touch control device and an operating method of the mutual capacitive type touch control device. The device comprises a plurality of first electrode pad serials and a plurality of second electrode pad serials. The first electrode pad serials are respectively provided with a plurality of first electrode pads, wherein the areas of the first electrode pads are equal, and the first electrode pads of each first electrode pad serial are coupled in series. The second electrode pad serials are respectively provided with a plurality of second electrode pads, and the areas of the second electrode pads of the second electrode pad serials increase progressively in sequence, wherein each second electrode pad is adjacent to each corresponding first electrode pad. Therefore, the mutual capacitive type touch control device has a single-layer structure and a multi-point touch control function at the same time.

Description

technical field [0001] The present invention relates to a touch device, in particular to a mutual capacitive touch device and an operation method thereof. Background technique [0002] With the rapid development and application of information technology, wireless mobile communications, and information home appliances, many information products have been transformed from traditional input devices such as keyboards or mice in order to achieve more convenient portability, lighter volume, and more user-friendly operation. To use the touch panel (TouchPanel) as an input device. [0003] At present, touch panels can be mainly divided into two types, one is a resistive touch panel, and the other is a capacitive touch panel. For a resistive touch panel, the user needs to actually apply pressure on the resistive touch panel to make some areas inside the resistive touch panel conduct and generate corresponding coordinate signals. Therefore, the resistive touch panel The damage rate ...
