Abstract

The embodiment of the invention provides a touch panel, a touch device and a manufacturing method of the touch panel. The touch panel comprises a substrate, a bridge electrode layer, an insulating layer, a first shadow eliminating layer and a touch electrode layer which are stacked in the thickness direction of the touch panel. The touch electrode layer comprises a spacing part and a bridge touch electrode, and the bridge electrode layer comprises a plurality of conductive bridges which are arranged at intervals. The first shadow eliminating layer and the insulating layer are stacked between the bridge electrode layer and the touch electrode layer. The touch panel further comprises bridging parts, and the bridging parts are electrically connected with the conductive bridges and the corresponding bridge touch electrodes. According to the touch panel provided by the embodiment of the invention, the insulating layer and the first shadow eliminating layer are arranged between the touch electrode layer and the bridge electrode layer, so that the distance between the touch electrode layer and the bridge electrode layer is increased, the capacitance of the touch panel is reduced, the signal-to-noise ratio of the touch panel is improved, and the sensitivity of the touch function of the touch panel is further improved. Meanwhile, the shadow eliminating effect on the touch electrode layer can be improved, and the color difference of the touch panel is reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic products, and in particular relates to a touch panel, a touch device and a manufacturing method of the touch panel. Background technique [0002] With the development of smart terminals, touch technologies such as touch panels have gradually become the mainstream of human-computer interaction control methods. And work brings greater convenience. [0003] A touch panel usually includes a plurality of touch electrodes. When a conductor, such as a finger of a human body, touches the touch panel, it will cause a change in capacitance between the touch electrodes or between the touch electrode and the ground. According to the change in capacitance, The touch position can be determined so that the touch device can receive touch signals and respond accordingly. However, in some cases, when the operator operates the touch panel, the touch panel may be unresponsive or even unresponsive, that is, the t...
