Abstract

An organic thin-film-transistor (OTFT) driven color flexible ferroelectric-liquid-crystal (FLC) display with 160 × 120 pixels and a resolution of 50 ppi has been developed. The flexible FLC was fabricated on a pentacene-OTFT array using printing and lamination techniques. To drive the display at a fast driving speed, an OTFT was developed with a short channel length having a large current output. The fabricated OTFT array with a channel length of 5 μm exhibits a carrier mobility of 0.3 cm²/V-sec and an ON/OFF ratio of over 10⁷ at a low drain voltage of -6 V. A field-sequential- color system with a flexible backlight unit was also developed and used to drive the display. Color moving images were successively shown on the 5-in. display using an active-matrix driving technique of the OTFT.
