We have made a prototype of flexible display system integrated with bend-input function. It consists of flexible display, flexible backlight unit with bending sensor, and MPU connected to PC. Zooming in/out in Google Earth and paging up/down in PDF files have been successfully done by bending the flexible display.

A novel formation process for TFT using our proposed novel selective transfer technique, which enables low cost TFT fabrication on a large and flexible substrate, is proposed. This technique is used to fabricate a 3.2-inch LCD Panel using amorphous silicon TFT transferred on glass substrate for the first time.

A 2.8″-diagonal reflective image-memory LCD using ferroelectric film for memory elements, which enables ultra-low-power consumption, is fabricated on a glass substrate for the first time. The asymmetrical feature of the hysteresis loop is improved by symmetrical ferroelectric capacitor configuration, and achieved an image-memory color LCD with good quality.

A novel image-memory LCD using ferroelectric film for memory elements with gray-scale capability and ultra-low-power consumption has been proposed. We have demonstrated the operation of image-memory function by using an LC cell with discrete ferroelectric devices. A gray-scale image without any power consumption for more than several seconds has been obtained.
