Patent ID: 8665230

Claim:
A sensing display device, comprising: a display panel, comprising; an array substrate; an opposite substrate having an outer surface; and a plurality of pixel units located on the array substrate, wherein the pixel units are arranged along a primary direction; and a sensing element, formed on the outer surface of the opposite substrate, the sensing element comprising: a plurality of first serials, wherein each of the first serials comprises: a plurality of first electrodes, each of the first electrodes comprising: a plurality of first traces substantially extended along a first direction, wherein a first angle is formed between the first direction and the primary direction, the first angle is an acute angle, a line width of one of the first traces is 0.1 μm to 100 μm, and a material of one of the first traces comprises aluminum, copper, molybdenum, titanium, silver, gold, platinum or alloy thereof; and a plurality of second traces perpendicular to the first traces to form a plurality of grids arranged in periodicity; and a plurality of bridge lines connected to the first electrodes, wherein one of the bridge lines is connected between two adjacent first electrodes; a plurality of second serials, wherein each of the second serials comprises a plurality of second electrodes, each of the second electrodes comprising: a plurality of third traces substantially extended along a second direction, wherein a second angle is formed between the second direction and the primary direction, the second angle is an acute angle, a line width of each of the third traces is 0.1 μm to 100 μm, and a material of each of the third traces comprises aluminum, copper, molybdenum, titanium, silver, gold, platinum or alloy thereof; and a plurality of fourth traces perpendicular to the third traces to form a plurality of grids arranged in periodicity, wherein a sensor unit is constituted by one of the first electrodes and one of the second electrodes; a passivation layer covering the first serials and the second serials; and a plurality of dummy electrodes disposed between the first electrodes and the second electrodes, wherein each of the dummy electrodes are floated and comprises: a plurality of fifth traces, substantially extended along a third direction, wherein a third angle is formed between the third direction and the primary direction, and the third angle is an acute angle; and a plurality of sixth traces, perpendicular to the fifth traces, wherein the first, second, third, fourth, fifth and sixth traces are straight lines.
