The manufacture of displays has always been an energy-intensive endeavour, and one of the key reasons for this is the production of transistors over large areas. Whether the display be LCD or OLED, transistors are needed behind each and every one of the millions of pixels across the display.
Most commonly, these transistors are made of silicon, on a glass substrate, and require temperatures during manufacture of up to 450°C or more, depending on the type. Furthermore, the deposition of the transistor materials themselves (silicon and dielectrics) involve the use of very energy-intensive, high temperature and vacuum processes, such as Chemical Vapour Deposition (CVD),…
