  • A new driving circuit for scan electrode in AC PDP has been developed. The number of scan driver switches can be reduced to one half of the conventional circuit. Capacitance between the electrodes is utilized. Experiments and analysis of the new structure has been carried out to confirm its robustness.

  • Transistor slicing refers to the use of multiple smaller transistors in implementing a large MOS transistor. What is special about transistor slicing is that it can reduce the effects of device non-uniformity introduced during the fabrication process. The paper presents the idea of transistor slicing and analyzes the benefits of using transistor slicing in the context of Poly-Si TFT-LCD driving.

  • We are suggesting a new index to represent the performance of PDP, such as Specific Performance Index (SPI) that includes luminous efficacy and panel reflectance. High Xe gas mixture and low panel capacitance are well known as key factors to improve luminous efficacy of PDP [1]. However, higher driving voltage and longer discharge time lag is an obstacle when applying these technologies. Modified cell design, new materials and driving waveform enable us to overcome these obstacles. High efficient phosphor is also a key material to improve luminous efficacy. Phosphors coated with pigment are used to reduce panel reflectance. High performance 50-inch HD PDP with luminous efficacy of 2.3 lm/W has been developed.

  • We will report the latest developments in light emitting polymer (LEP) systems developed at CDT. Device performance for spin coated and ink jet printed systems will be described which are state-of-the-art. We will also report on novel driving schemes for both active and passive addressed LEP displays. These drive schemes extend system lifetime as well as lowering power consumption.

  • LGE developed and demonstrated the first 60-inch full color AC plasma display panel with the 1365 ${\times}$ 768 resolution. Both Sol-gel and E-beam method have been tried for MgO layer, and photolithography has been used for electrodes and phosphor layer to fabricate a 60-inch panel. Selective Erase, Selective Write, Address Display Separate, and Address While Display driving scheme have been tested. Its luminance and contrast ratio is about $550\;cd/m^2$ and 500:1, respectively.

  • A variety of power reduction technologies is introduced and the benefits of the technologies are discussed. PenTile$^{(R)}$ DBLC (Dynamic Brightness LED Control) combined with SABC (Sensor-Based Adaptive Brightness Control) enables to achieve the average LED power consumption to one third. The panel power reduction of 25% can be achieved with low power driving technology, ALS (Active Level Shifter). MIP (Memory In Pixel) is expected to be useful in transflective display because the whole display area can be utilized in reflective mode with power consumption of 1mW.

  • Blue-white reflective cholesteric liquid crystal display was prepared by a unique method of single liquid crystal layer, the combination of yellow color liquid crystal and blue color backplane. The dopant and host combination of chlolesteric liquid crystal affects the color spectrum. The CIE chromaticity coordinates of blue and white are (0.10, 0.16) and (0.29, 0.30), respectively. The relatively low driving voltages of 32 V for blue-white display are obtained.

  • We proposed driving method with variable integration time for ambient light sensing. One operation period of the proposed driving method consists of several sub-integration periods with variable integration time which can enlarge dynamic range of ambient light sensing circuit. Temperature dependent characteristic of p-intrinsic-metal (p-i-m) diode can be compensated using the proposed driving method.

  • We reported the result of driving PDP's in selective erase scheme and three wall charge states. Compared to the selective write driving scheme, the selective erase scheme achieved flicker free half-ON state with much simpler driving waveforms than the selective write scheme. We believed that this improvement was possible since the cells entering the address period with enough wall charges to modulate easily with.
