Graphene flexible touchscreen with integrated analog-digital converter

Graphene flexible touchscreen with integrated analog-digital converter The possibilities of developing a projection-capacitance touchscreen which aligns sensors and an analog-digital converter produced from the material based on graphene have been considered.

The touchscreen is a film with a thickness of 100–150 micrometers with alternating graphene layers, which transmit 6–8% more light than a projection-capacitance screen from indium and stanum oxides. The screen is highly flexible, is mechanically hard, and the materials—saccharose, copper foil, boron nitride (BN), etc.—used to fabricate it potentially cost less.

Abstract

The possibilities of developing a projection-capacitance touchscreen which aligns sensors and an analog-digital converter produced from the material based on graphene have been considered. The alignment of these two elements will make it possible to implement a touchscreen with digital signals at the output contacts which will make it possible to connect it to the integrated logical circuits of the control system. The touchscreen is a film with a thickness of 100–150 micrometers with alternating graphene layers, which transmit 6–8% more light than a projection-capacitance screen from indium and stanum oxides. The screen is highly flexible, is mechanically hard, and the materials—saccharose, copper foil, boron nitride (BN), etc.—used to fabricate it potentially cost less. This is achieved by the application of a complex of the known methods used to obtain films from two-dimensional materials based on graphene of a preset configuration on flexible polymer substrates and a single construction of the system for electrical capacitance accumulation in a touchscreen and analog-digital conversion on graphene field-effect transistors.
