Problems solved by technology
In order to improve product quality and yield, additional components need to be installed in response to different needs. For example, in order to prevent the surrounding leads and sensing layer from being oxidized or affected by other processes, it is necessary to set up protection on the surrounding leads and sensing layer respectively. layer; in order to improve the visual appearance of the touch sensing device, functional components such as optical compensation need to be installed in the perspective part, which leads to complicated manufacturing process and structure

The invention provides a touch sensing device and a manufacturing method thereof. The touch sensing device comprises a substrate, a peripheral lead, a bridging component, a conductive pattern layer, an insulating layer and a refractive index matching protection layer. The peripheral lead is arranged on the periphery of the substrate. The bridging component and the conductive pattern layer are arranged on a perspective part of the substrate. The conductive pattern layer comprises a pattern part and a non-pattern part. The pattern part comprises a first axial electrode and a plurality of second conductive units, wherein the first axial electrode is electrically connected with part of the peripheral lead, and the adjacent second conductive units are electrically connected through the bridging component and are electrically connected with the other part of the peripheral lead. The peripheral lead is covered with the first part of insulating layer, and the second part of the insulating layer is arranged between the bridging component and the conductive pattern layer. The conductive pattern layer is covered with the refractive index matching protection layer and is used for enabling the refractive index of the pattern part to be matched with the refractive index of the non-pattern part. Thus, two using purposes can be achieved through the same component, and the processing steps and structure can be simplified.
Description
technical field [0001] The invention relates to an input interface and a manufacturing method thereof, in particular to a touch sensing device and a manufacturing method thereof. Background technique [0002] Touch technology has developed rapidly in recent years, and many consumer electronic products have products combined with touch functions. Currently, common touch panel technologies include resistive, capacitive, and optical. Among them, the capacitive touch panel has gradually become the mainstream touch technology used in mid-to-high-end consumer electronic products due to its high accuracy, multi-touch, high durability, and high touch resolution. [0003] The surface area of a conventional touch sensing device can be roughly divided into a see-through portion and a peripheral portion, and the peripheral portion is located on at least one side of the see-through portion. The see-through part is provided with elements such as a sensing layer for touch sensing. The...
