    Abstract: The present disclosure provides a method of fabricating a graphene touch sensor, a graphene sensor and a touch-sensitive display device. The method comprises: forming a graphene layer on a substrate; forming a metal layer on the graphene layer; coating a photoresist layer on the metal layer; exposing the photoresist layer by using a gray-scale reticle and developing the exposed photoresist layer to obtain a photoresist completely removed region, a photoresist partially remained region, and a photoresist completely remained region; removing the metal layer located in the photoresist completely removed region; removing the graphene layer located in the photoresist completely removed region; removing the metal layer located in the photoresist partially remained region; coating a protective film on the graphene layer located in the photoresist partially remained region; striping off the remainder photoresist. The embodiment of the present disclosure avoids the alkaline developing solution and the alkaline stripping solution from contacting the graphene film to degrade the conduction of the graphene, thereby increasing yield and reducing cost.

    Abstract: An embodiment of this disclosure provides a nano-imprinting method, including: applying an imprinting adhesive on a to-be-processed layer of a substrate located in an imprinting chamber; charging the imprinting chamber with a preset gas at a temperature higher than a boiling point of the preset gas, and pressing a nano-imprinting template on the imprinting adhesive; reducing an ambient temperature of the imprinting chamber to a temperature lower than the boiling point of the preset gas and maintaining the temperature for a preset time, such that the preset gas becomes a liquid; irradiating ultraviolet light from a side of the nano-imprinting template away from the imprinting adhesive to cure the imprinting adhesive; raising the ambient temperature of the imprinting chamber to be higher than the boiling point of the preset gas, such that the liquefied preset gas turns back into a gas; and demolding the nano-imprinting template from the imprinting adhesive.

    Abstract: A touch panel and a method for fabricating the same are disclosed. The method for fabricating the touch panel forms a pattern of a protruding structure on a base substrate by using a negative photoresist material, and the pattern of the protruding structure formed thereon is a pattern having a cross section which gradually increases from the base substrate to the outside surface and is similar to an inverted trapezoidal. Thereafter patterns of a touch electrode and dummy electrode insulated from each other are formed by using the pattern of the formed protruding structure as a mask. As the pattern of the touch electrode and the dummy electrode are disconnected through level difference of the protruding structure, the patterns of the touch electrode and the dummy electrode overlay the whole base substrate from the top view, allowing the whole surface of the touch panel to have the same optical property.
