Authors: Nichols J. A. , Jackson T. N. , Lu M. H. , Hack M. 
Published: January 2005

AbstractWe report a two‐transistor amorphous silicon (a‐Si:H) thin film transistor (TFT) active‐matrix organic light emitting diode (OLED) pixel using high‐efficiency phosphorescent OLED devices. The gate to source voltage (VGS) for the OLED drive transistor is less than 8 V for a pixel brightness of 100 cd/m2and less than 12 V for 400 cd/m2. The low drive voltage is important for good TFT stability and display uniformity.

Authors: Noh Jeong‐Dong , Kim Hyang Yul , Kim Jin Mahn , Koh Jai Wan , Lee Jung Yeal , Park Hae Sung , Lee Seung Hee 
Published: January 2005

AbstractWe have developed a pixel structure of the Ultra‐fringe‐field switching (FFS) TFT‐LCD using the LCs with positive dielectric anisotropy for superior pressure‐resistant characteristic. We have improved the pressure‐resistant characteristic of the “Ultra‐FFS” device by changing ‘⁁’ shape of pixel electrode into ‘<’ shape in one pixel. This indicates that its excellent electro‐optical characteristics remained unchanged under external pressure and thus the device can be applied to position‐ and pressure‐ sensitive touch panel display.

Published: January 2005

AbstractWe study the front‐of‐screen performance and optimal coil design for various deflection angles. Both normal scanning and transposed scanning are considered. In these investigations the energy dissipation in the coil is controlled. We find that the convergence errors grow with increasing deflection angle. Transposing the scanning direction reduces the convergence errors significantly. Thus coils with deflection angles up to 130° with good geometry and convergence can be designed.

The devices function well at temperatures down to—20°C, sustain switching stability of at least two million cycles, and show promising stability under UV illumination, temperature storage (−20°C to +80°C) respectively humidity.
P‐33: A Measurement and Analysis Method of Image Sticking in LCD
Authors: Lee Don‐Gyou , Kim Il‐Ho , Soh Hoe‐Sup , Ann Byung Chul 
Published: January 2005

AbstractIn this paper, the evaluation method of image sticking was proposed by measuring 2‐Dimension of luminance level. We used the 2D‐CCD luminance meter and pattern generator for chessboard pattern. The test samples were burned in about 2 hours and the tested data were normalized by data before image sticking test. The normalized value was so sensitive for determining the image sticking level. We proposed a new parameter of ISV(image sticking value) for increasing sensitivity. It was resulted that the image sticking under ISV 1% was difficult to be detected by human eye. And the image sticking over ISV 2% was strongly detected. It was found that this test method is similar to human eye testing result. Therefore, this analysis method helps to determine the objective image sticking level.

AbstractMinimizing the spatial variation of polarization is critical to tiled AMLCD image quality. With the advent of large tiled AMLCD, low spatial frequency artifacts may become visible. Component birefringence variation of a few nanometers can produce viewer detectable luminance variations.

AbstractIt is estimated that a porous polysilicon (PPS) diode with a structure of Au/PPS/n‐type Si operates as an efficient stable surface emitting cold cathode. 2.0 μm of an nondoped polysilicon layer is formed on an heavily doped n‐type silicon wafer and anodized in a solution of HF(50%): ethanol = 1: 1 under illumination by a 500 W tungsten lamp from a distance of 20 cm. The electron emission properties of the PPS diode were investigated as a function of anodizing condition. It was found that the electron emission properties depend on the anodizing condition, and the optimum anodizing condition is 10mA/cm2 for 15 seconds. The PPS diode emitter fabricated by using the optimum condition has higher efficiency, lower diode current and higher emission current compared to that of other PPS diode emitter. The electron emission characteristics as a function of ambient pressure and the electron trajectory were also studied. Furthermore, the fluctuation properties of the PPSE was investigated and discussed.

Published: January 2005

AbstractWe investigated the secondary electron emission characteristics of MgO layer used as the protecting material in a.c. plasma display panel(a.c.‐PDPs) using a pulsed ion beam technique, where the surface charging can be effectively suppressed during the measurement. The measurement of the secondary electron emission coefficients γifor He+, Ne+, Ar+, Kr+ and Xe+ ions with kinetic energies ranging from 50 eV to 225 eV showed an energy dependency increasing gradually as a function of kinetic energy. In addition, it was clearly demonstrated that the pulsed ion beam method can successfully measure the coefficient of secondary electron emission from insulator surfaces.

Published: January 2005

AbstractPolymer‐stabilized ferroelectric liquid crystal (PS‐FLC) cells with high display performance have been developed and reported by our group, mainly through experiments. There are two types of PS‐FLC cells, exhibiting a Half‐V shaped and a V‐shaped EO characteristic, which are controlled by the condition of photocure treatment. In this paper, we show the V‐shaped switching characteristics of PS‐FLC cells by a computer simulation; some numerical models have been suggested and established using the continuum theory by introducing the term of polymer stabilization. It is shown that simulated results agree well with experimental results.
P‐74: A Noble Driving Method for Frustrated AFLCs
Authors: Kang Jin‐Woo , Park Won Sang , Juhn Chul Gyu , Han Kwan‐Young , Yoon Tae‐Hoon , Kim Jae Chang 
Published: January 2005

AbstractFrustrated AFLCs exhibit a sharp decline of holding voltage when they are driven by TFTs for high quality displays. The reason is that the response time of the LCs is longer than the gate pulse width, and frustrated AFLCs have large spontaneous polarization. The sharp decline of holding voltage becomes the cause of low contrast, and is an important problem to be considered in designing LCDs. In this paper, to solve this problem we propose a noble M‐sector driving method and a new gray‐implementation method.
