Problems solved by technology

However, since the bonding area has the densest lines and relatively large conductive area, when the pen tip of the active pen touches the bonding area of ​​the border area, it is easy to generate false sensing (false alarm points) in the display touch area, or even actively When the tip of the pen touches the line in the border area, there will also be a small amount of induction

Abstract

A touch panel defines a touch area and a frame area surrounding the touch area. The touch panel comprises an insulating substrate with an upper surface and a lower surface which are opposite to each other, the upper surface is provided with a plurality of first touch electrodes, the lower surface is provided with a plurality of second touch electrodes, and the first touch electrodes and the secondtouch electrodes are located in the touch area. The touch panel further comprises a plurality of first wires which are arranged on the insulating substrate and located in the frame area, one end of each first wire is connected with the corresponding first touch electrode, the other end of each first wire is connected with the corresponding first connecting pad; the first connecting pads are arranged on the upper surface, a conductive layer is arranged on the lower surface, and the projection of the conductive layer on the insulating substrate along the normal direction of the insulating substrate surrounds each first connecting pad and is not overlapped with the first connecting pad in a contact manner. The invention further provides a touch display device applying the touch panel. The conductive layer surrounding the first connecting pad is arranged on the insulating substrate, so that the false alarm points caused by the fact that an active pen touches the frame area can be effectively avoided.

Description

technical field [0001] The invention relates to a touch panel and a touch display device using the same, in particular to a touch display device equipped with a touch pen. Background technique [0002] Existing touch display devices generally include a touch panel and a display panel arranged in layers. The touch display device defines a display touch area and a frame area surrounding the display touch area. A touch panel usually includes a base material, a plurality of touch driving (Tx) electrodes, an insulating layer and a plurality of touch sensing (Rx) electrodes stacked on the surface of the base material in sequence, and the insulating layer is stacked on the plurality of Tx electrodes and the plurality of touch sensing (Rx) electrodes. Between the plurality of Rx electrodes, the substrate is also provided with a plurality of metal leads electrically connected to the Tx touch electrodes and the Rx electrodes respectively, wherein the Tx electrodes and the Rx electrod...
