Review of the feasibility of a new touch-sensitive digital display enabled by block copolymer materials

Abstract

Nowadays, electronic devices are widely used, and as an important part of many electronic devices, human-computer interaction displays have a lot of room for development. At present, traditional touch displays typically incorporate materials such as indium tin oxide (ITO) or graphene, which have limitations such as inflexibility, average accuracy and needing external power supplies. This article describes a motion sensor without additional power supply, which is based on one-dimensional photonic crystals of interpenetrating hydrogel network block copolymer (IHN-BCP), composed of photonic crystals alternating between different layers. The article concentrates on the viability of addressing these difficulties. The result shows that Block copolymers are unique polymers consisting of two or more distinct polymer chains, with the potential to exhibit self-assembling behaviour. Due to the special properties of block copolymer, this display could have flexible substrates and detect various contact and non-contact human motions. This device can be applied to interactive screens for cell phone screens, factory equipment, and other electronic products, and can also provide a reference for the future development of flexible screens.
