Both glass-based and film-based sensors are evolving to improve performance, while at the same time becoming thinner and lighter, and increasing optical quality.

The latest report from NPD DisplaySearch forecasts that the total touch sensor area yield of projective capacitive, in-cell, on-cell, and resistive sensors, will reach 23.3 million square meters in 2015, up from 18 million square meters in 2014. Capacity for sensors for film substrates will be higher than for glass substrate, due to expected area growth of each type of film structure.
