Flexible active-matrix electronic ink display U ltrathin, flexible electronic displays that look like print on paper are of great interest 1-4 for application in wearable computer screens, electronic newspapers and smart identity cards. Here we realize the fabrication of such a display on a bendable active-matrix-array sheet. The display is less than 0.3 mm thick, has high pixel density (160 pixels ǂ240 pixels) and resolution (96 pixels per inch), and can be bent to a radius of curvature of 1.5 cm

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 cm2/Vs and an ONiOFF ratio of 5~1 0~. TFT characteristics under biastemperature-stress and mechanical strcss are discussed. These 0.3mm thick displays have 96dpi resolution, with 160x240 pixels on a 3.1" diagonal active area. Near 180" viewing angle and a contrast ratio of 8.5: 1 were achieved.
