Touch Panel and Display Device

摘要

A touch panel includes a plurality of sensing lines disposed in a sensing area, a plurality of touch-controlling lines disposed in a touch-detecting area, and an extended sensing line. The plurality of sensing lines are used for generating sensing signals, and the plurality of touch-controlling lines are used for receiving touch-controlling signals. The plurality of touch-controlling lines are extended to the sensing area to form mutual capacitances. The sensing line stretches into the touch-detecting area as the extended sensing line, forming a mutual capacitance in the touch-detecting area. It decreases the dead areas effectively and makes the positioning of touches more accurate.
