Abstract
A capacitive touchscreen includes a substrate and a transparent conductive layer arranged on the substrate. The conductive layer includes a sensing area. The sensing area has a first side and a second side opposite to the first side. The capacitive touchscreen further includes multiple transparent and conductive first electrodes, multiple transparent and conductive second electrodes, and transparent and nonconductive patterns. Each first electrode includes a first trunk extending from the first side toward the second side. Each second electrode includes a second trunk and a wiring coupled to the second trunk. Both the second trunk and the wiring extend from the first side toward the second side, and each second trunk cooperates with a corresponding first trunks to be operable to sense a touched position. The transparent and nonconductive patterns are located between the first and second electrodes to electrically isolate the first electrodes from the second electrodes.
