Abstract :
Ultra-thin, flexible displays were fabricated using electronic ink and a-Si TFT backplanes on stainless steel foil substrates. The fabricated TFTs have a linear mobility of 0.5 cm/sup 2//Vs and an ON/OFF ratio of 5/spl times/10/sup 6/. TFT characteristics under bias-temperature-stress and mechanical stress are discussed. These 0.3 mm thick displays have 96 dpi resolution, with 160/spl times/240 pixels on a 3.1" diagonal active area. Near 180/spl deg/ viewing angle and a contrast ratio of 8.5:1 were achieved.
