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 includes an insulating substrate with opposite upper and lower surfaces, the upper surface is provided with a plurality of first touch electrodes, the lower surface is provided with a plurality of second touch electrodes, the first touch electrodes and the second touch electrodes The electrodes are located in the touch area. The touch panel also includes a plurality of first wirings arranged on the insulating substrate and located in the frame area, one end of each first wiring is connected to the first touch electrode, and the other end is connected to the first connection pad, and the first connection pad set on the upper surface. A conductive layer is disposed 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 connection pad and does not overlap with the first connection pad. The present invention also provides a touch display device using the above touch panel. By arranging the conductive layer surrounding the first connection pad on the insulating substrate, it is possible to effectively avoid false alarm points caused by the active pen touching the frame area.

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] The existing touch display device generally includes 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 drive (Tx) electrodes sequentially stacked on the surface of the base material, an insulating layer and a plurality of touch sensing (Rx) electrodes, and the insulating layer is stacked on the plurality of Tx electrodes and all the touch sensing (Rx) electrodes. Between 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 Tx electrodes and the Rx electrodes are arranged i...
