Problems solved by technology

For the current OGS touch screen, due to the electrode bridge design of the sensor layer and the limitation of film thickness, it is more susceptible to ESD damage
At present, there is no effective protection mechanism for the release of static electricity accumulation on the sensor layer of the OSG touch screen and the generation of induced static electricity during the manufacturing process, and product failures caused by ESD events frequently occur

Abstract

The embodiment of the invention relates to a touch sensor and a production method thereof, and a touch panel. The touch sensor comprises a base plate, an electrode layer, a first insulating layer and a transparent conductive layer, wherein the electrode layer is arranged on the base plate, wherein the electrode layer consists of a first electrode and a second electrode which are isolated from each other; the first insulating layer is arranged on the electrode layer; the transparent conductive layer is arranged on the first insulating layer, wherein the transparent conductive layer consists of a bridging part and an ESD protective part, the bridging part is arranged to be bridged with the first electrode or the second electrode, and the ESD protective part is isolated from the bridging part. According to the touch sensor provided by the embodiment of the invention, the antistatic capability of a functional layer inside the sensor can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of touch display, and in particular, to a touch sensor, a manufacturing method thereof, and a touch panel. Background technique [0002] The touch screen is a widely used external input device. It can realize input by lightly touching the screen with a finger, which makes the human-computer interaction more direct, and has the characteristics of simplicity, speed and humanization. [0003] There are various types of touch screens. Among them, the OGS (One Glass Solution, integrated touch) touch screen is a technology that directly forms an ITO (Indium Tin Oxides, indium zinc oxide) conductive film and sensor on a glass substrate. OGS touch screen has the advantages of thinness, high transmittance and suitable for medium and large size products, and has occupied most of the touch market. [0004] Electro-Static discharge (ESD, Electro-Static discharge) is a sudden and instantaneous curr...
