Capacitive touchscreens

A capacitive touchscreen, comprising:

• a substrate;
• a transparent and conductive layer arranged on the substrate, the conductive layer comprising a sensing area, the sensing area having a first side and a second side opposite to the second side;
• a plurality of transparent and conductive first electrodes, each of the plurality of transparent and conductive first electrodes comprising a first trunk extending from the first side toward the second side along a straight line;
• a plurality of transparent and conductive second electrodes, each of the plurality of transparent and conductive second electrodes comprising a second trunk and a wiring coupled to the second trunk, the wiring of each of the transparent and conductive second electrodes extending from the first side toward the second side, the second trunk of each of the plurality of transparent and conductive second electrodes extending from the first side toward the second side along a straight line, the second trunk of each of the plurality of transparent and conductive second electrodes cooperating with a corresponding first trunk to be operable to sense a touched position;
• a plurality of transparent and nonconductive patterns arranged between the plurality of transparent and conductive first electrodes and the plurality of transparent and conductive second electrodes to electrically isolate the plurality of transparent and conductive first electrodes from the plurality of transparent and conductive second electrodes.
