TCL CSoT, in collaboration with Guangdong Aosu Liquid Core Micro-Nano Technology, have demonstrated a new active-matrix Electrowetting on Dielectric (EWOD) display prototype. This seems to be an early stage project, but could be an interesting one to follow.
The prototype shown by TCL is a 2.8-inch active-matrix display, with a resolution of 128x64 (a total of 8,192 pixels), on an IGZO backplane.
An electrowetting display is made from small cells that contain transparent polar liquid colored oil, that both cover a hydrophobic surface. The oil is controlled by voltage that is applied to the cells, that contracts the oil which creates an optical switch.
Electrowetting displays have been developed in the past, and was thought promising. The main developer was a company called Liquavista, that was acquired by Samsung, and later by Amazon until it was shut down in 2018. It is great to see renewed interest in this technology.
