Litton Systems Canada has been engaged in developing CdSe active matrix LCD
s for many years. CdSe has much higher mobility compared to amorphous silic
on, which is the most popular choice for TFTs at present. The high mobility
, low temperature process, low cost and ease in fabrication give CdSe TFTs
many advantages over amorphous and polycrystalline silicon for high resolut
ion and large area cells. This paper describes the electro-optical characte
ristics such as contrast ratio and viewing angle of CdSe active matrix TN L
CDs fabricated at Litton.
