58.5: Late-News Paper: 14.3 inch Active Matrix-Based Plastic Electrophoretic Display Using Low Temperature Processes

A 14.3-inch black and white plastic electrophoretic display (EPD) was developed at the resolution of 1280 × 900 lines (112 ppi). All of the processes of TFT and electrophoretic sheet (EPS) lamination were not only carried out below 120°C, but also optimized for large area TFT-EPD on PEN plastic films.

34-3: Transmissive 7″ VGA a-Si TFT Plastic LCD Using Low Temperature Process and Holding Spacer

A 7.0-inch transmissive type plastic TFT-LCD was developed at the resolution of 640 × 3 × 480 lines (114ppi). All of the processes of TFT, color filter and LC were carried out below 130 °C on PES plastic films. The process conditions of TFT, color filter and LC were optimized for large area TFT-LCD on plastic substrate. The backplane and the color filter was strongly adhered while the panel was bending by using holding spacers.
