Abstract: A touch screen contains a capacitive sensing layer, a first controller for detecting a touching position, a piezoelectric sensing layer, a second controller for detecting a touching pressure, and a main controller. The touch screen also comprises a window area and a non-window area, the capacitive sensing layer is arranged in the window area, the piezoelectric sensing layer is arranged in the non-window area. The first controller connects with the capacitive sensing layer, the second controller couples with the piezoelectric sensing layer, and the main controller is in connection with the first controller and the second controller. The first controller transmits a touching signal of the capacitive sensing layer to the main controller, and the second controller transmits a pressing signal of the piezoelectric sensing layer to the main controller, such that the main controller acquires the touching position and the pressure value on the touch screen.

Abstract: Improved methods for synthesizing large area thin films are disclosed, which result in films of enhanced width. The methods comprise providing a separator material which is rolled or wound up, along with the metallic foil substrate on which the thin film is to be deposited, to form a coiled composite which is then subjected to conventional chemical vapor deposition. Optionally, a winding tool may be used to aid in the rolling process. The methods enable a many-fold increase in the effective width of the substrate to be achieved.

Abstract: Aspects of the invention are directed to a method of forming a film on a substrate. The substrate and a solid carbon source are placed into a reactor. Subsequently, both the substrate and the solid carbon source are heated. Optionally, one or more process gases may be introduced into the reactor to help drive the formation of the film. The film comprises graphene.
