  • A 3.12" FED panel was packaged successfully using the anode plate on which phosphors and black matrix were coated and cathode plate containing emitter arrays. The vacuum level of the panel was investigated during panel evacuation, tip-off and getter activation process. The packaged panel exhibited vacuum level below 2${\times}$10-6 Torr. Similar experiments were carried out for 10" panel made of bare plates. In addition, the vacuum level of two panels was compared continuously after tip off process; one with the getter and the other without it.

  • Novel surface profiler system for inspection of the display components is demonstrated In the case of the liquid crystal display, for example, not only the flatness of the alignment film but also the quality of rubbing can be inspected. Furthermore, the shape of the component such as the color filter, electrode and mirror can be inspected without removing each component.

  • Since 2006, the Industrial Technology Research Institute and the University of Cincinnati have been jointly exploring approaches for high brightness flexible electrowetting displays (EWDs). Recently, ITRI demonstrated for the $1^{st}$ time a 6" AM-EWD reflective display panel. To create flexible AM-EWDs, Cincinnati has developed low-temperature processing and improved pixel structures.

  • We suggest a viewing angle control mode of liquid crystal display(LCD) with additive thermal controllable optical layer [TCOL], which composed of homeotropically or homogenously well aligned LC layer and patterned hating lines on a substrate. In this system, LCD modes with wide viewing angle characteristics can be used as a main panel.

  • LTPS has potential capability to realize various kinds of circuit integrations on panel glass because of its relatively higher field effect mobility of around 100cm2/Vs. Recent progress of LTPS technologies and advanced technologies, which are generally called "System on Glass (SOG)," will be discussed. The technology includes circuit integration, photo-sensor integration for input functions, and display quality and performance improvement.

  • For system-on-glass (SoG) with low-temperature poly-silicon (LTPS) thin film transistor (TFT), a new system interface architecture and timing controller are developed. With the newly developed system interface architecture, line memory can be eliminated which would take large area of SoG display panel. The system interface and timing controller are targeted for the application for 6-bit gray scale, 60-frames/s qVGA format.

  • Quick-Response Liquid Powder Display ($QR-LPD^{(R)}$) is a promising device for ultra-low-power applications. Several driving methods for this display were investigated in terms of image quality and power consumption. The power consumed both in a panel and in the output circuits of driver LSIs was evaluated by analog circuit simulation and discussed.

  • For lower power and smaller size with higher image quality, it is desirable to have more units integrated on a display panel. It needs careful design considerations in selecting CMOS, SOP or PCB. An experimental display system is designed and power and delay considering chip area, data rates and bus width are analyzed for all technology combinations to obtain optimum design methodologies.

  • Short channel a-Si:H TFT devices with Cu electrodes have been investigated. Short channel TFTs are defined by new plasma etch process. When the channel length becomes shorter, the TFT characteristics (threshold voltage, off current, sub threshold voltage, etc.,) are degraded. These degraded characteristics can be improved through the hydrogen plasma treatment and new gate insulator structure. Using these processes, 15.0 inch XGA LCD panel was fabricated successfully where the channel length of the TFT devices was about 2.5 micrometers.
