Touchpad and manufacturing method thereof as well as touch display panel with touchpad

Abstract

The invention provides a touchpad and a touch display panel with the same. The touch display panel comprises a display panel and the touchpad, and the touchpad comprises a touch unit and a transparent protective layer, wherein, the touch unit is configured on the display panel and is positioned between the display panel and the transparent protective layer; the transparent protective layer is coated on the touch unit and is made from photosensitive resins; and the transparent protective layer and the touch unit of the touch display panel are tightly integrated. In addition, the invention further provides a manufacturing method of the touchpad. The touchpad has a better touch effect; the touch display panel has a better touch effect and better display quality; and by utilizing the manufacturing method of the touchpad, air bubbles are avoided between the transparent protective layer and the touch unit.

Description

technical field [0001] The present invention relates to a touch panel, and in particular to a touch panel without a glass protective plate, a manufacturing method thereof, and a touch display panel with the touch panel. Background technique [0002] In recent years, touch display panels using touch detection technology have been widely used in many types of electronic products, especially portable electronic products, such as notebook computers, personal digital assistants ( Personal Digital Assistant), mobile phones, satellite navigation machines and electronic paper display devices, etc. [0003] A conventional touch display panel includes a stacked display panel and a touch panel, wherein the touch panel includes a touch unit and a glass protection plate, and the touch unit is disposed between the display panel and the glass protection plate. The touch unit includes a substrate and a detection component formed on the substrate, and the glass protection plate is used to p...

AI Technical Summary

Problems solved by technology

However, since the glass protection plate and the substrate of the touch unit are rigid materials, when the glass protection plate and the touch unit are bonded together, air bubbles are likely to exist between the glass protection plate and the touch unit

In this way, it will cause the problem that the bonding between the glass protective plate and the touch unit is not tight, which will affect the display quality or touch effect of the touch display panel.
