Problems solved by technology

[0003] However, when the thickness of the insulating layer is large, and the slope of the outer edge of the insulating layer relative to the surface of the substrate is relatively large, the Rx electrodes formed on the insulating layer overlap the metal leads of the non-touch area. When connected, it is easy to cause broken wires and other poor laps, which will affect the operation of the touch panel

Abstract

A touch panel defines a touch area and a non-touch area around the same; the touch panel include a substrate, a plurality of first touch electrodes, an insulating layer and a plurality of second touchelectrodes, wherein the first touch electrodes, the insulating layer and the second touch electrodes are stacked on the substrate in sequence; the first touch electrodes and the second touch electrodes are positioned in the touch area. The touch panel also includes a plurality of first lines and second lines in the non-contact area; the first lines are connected with the first touch electrodes, the second lines are connected with the second control electrodes, the non-touch area is provided with a binding area such that the lines are connected to a control circuit; the binding area is provided with a plurality of connection pads connected with the lines; the second touch electrodes form multiple extension lines in the non-touch area; each extension line is extended the binding area and isin covering lap joint with one connection pad. The touch panel ensures that the second touch electrodes are electrically connected with the control circuit, and touch sensing effect is effectively improved.

Description

technical field [0001] The invention relates to a touch panel and a touch display device using the same. Background technique [0002] In the prior art, a touch panel usually includes a substrate, a plurality of touch drive (Tx) electrodes stacked on the surface of the substrate in sequence, an insulating layer and a plurality of touch sensing (Rx) electrodes, wherein the insulating layer is stacked on the surface of the substrate. Between the plurality of Tx electrodes and the plurality of Rx electrodes, a plurality of metal leads electrically connected to the Tx touch electrodes and the Rx electrodes are further arranged on the substrate. Wherein the touch panel can be divided into a display touch area and a peripheral circuit area, the plurality of Tx electrodes and a plurality of Rx electrodes are arranged in the display touch area, and the plurality of metal leads are arranged in the peripheral circuit area, each The metal leads are electrically connected to the corres...
