Capacitive touch screens are a widely used technology in modern electronic devices, relying on specific materials to enable touch sensitivity. The primary materials involved in capacitive touch screens include indium tin oxide (ITO), glass, and various layers of coatings.

Small touch screens, a ubiquitous feature in modern electronic devices such as smartphones, smartwatches, and compact displays, offer a plethora of advantages owing to their size and touch-sensitive capabilities. Their compact dimensions contribute significantly to enhanced portability and user convenience.
