Touch control panel with flexible touch control sensor and fabrication method of touch control panel

Abstract

The invention relates to the technical field of touch control, and provides a touch control panel with a flexible touch control sensor. The touch control panel comprises the flexible touch control sensor and a cover plate, wherein the cover plate and the flexible touch control sensor are in close contact through an adhesive layer, the flexible touch control sensor at least comprises a sensing electrode structure arranged on a flexible substrate, the sensing electrode structure comprises a first insulation membrane layer and a first patterned conductive layer, the first patterned conductive layer is formed on the first insulation membrane layer, and the first insulation membrane layer is arranged between the flexible substrate and the first patterned conductive layer and is in direct contact with the flexible substrate. By arranging the flexible touch control sensor in the touch control panel, the cover plate of the touch control panel is free from the limitation of a planar structure, and different design demands of a product are further met. Further, the invention also provides a fabrication method for the touch control panel with the flexible touch control sensor.

Description

technical field [0001] The invention relates to the field of touch technology, in particular to a touch panel with a flexible touch sensor and a manufacturing method thereof. Background technique [0002] With the development of touch technology, touch panels have been widely used in various electronic products, such as mobile phones, notebook computers, tablet computers, digital cameras, electronic photo albums, etc., for users to perform input operations. [0003] The structure of a traditional touch panel generally includes a cover plate and a touch sensing layer. Since the material forming the touch sensing layer is generally a non-bendable conductive material such as indium tin oxide, the touch sensing layer is usually formed directly. On the cover plate, or pre-formed on a hard substrate, and then bonded to the cover plate through an adhesive layer, and the surface of the touch sensing layer formed by the cover plate and or the substrate can only be a planar structure,...

[0003] The structure of a traditional touch panel generally includes a cover plate and a touch sensing layer. Since the material forming the touch sensing layer is generally a non-bendable conductive material such as indium tin oxide, the touch sensing layer is usually formed directly. On the cover plate, or pre-formed on a hard substrate, and then bonded to the cover plate through an adhesive layer, and the surface of the touch sensing layer formed by the cover plate and or the substrate can only be a planar structure, in other words, The touch sensing layer in traditional touch panels can only be formed on a carrier (cover or substrate) with a certain hardness and flat surface due to the limitation of its own materials. As a result, the application range of touch panels is limited. Certain restrictions, that is, it can only be applied to products with a flat input operation surface, but cannot be applied to products with a certain curvature of the input operation surface, so that it cannot meet the development needs of products
