P‐82: Relationship of Moving Edge Color Distortion and Response Spectrum
Authors: Enami Yoshi 
Published: January 2009

AbstractMoving edge color distortion is a phenomenon that is often seen in PDP‐TVs and other displays that use a phosphor and in displays using field sequential drive. By observation using a moving picture evaluation system using a color pursuit camera, which we have developed, we were able to confirm that moving edge color distortion also occurs in LCDs. In order to clarify the cause of moving edge color distortion in an LCD, the response of the LCD was measured using a high‐speed spectrometer, and as a result, we were able to confirm that wavelength dependence of retardation is a cause of moving edge color distortion.

Published: January 2009

AbstractAccurate colorimetric characterization is an important step in establishing the color management system (CMS) for liquid crystal displays (LCDs) to achieve device‐independent color reproduction. The gain‐offset‐gamma (GOG) model that is accurate enough in describing the tone reproduction curves (TRCs) for CRT displays has been found inadequate for characterizing LCDs due to mainly channel interaction and non‐constancy of channel chromaticity. In this paper, a modified GOG model that takes channel interaction and backlight leakage into account is proposed to accurately characterize the TRCs of LCDs. Experimental results indicate that the proposed model outperforms the conventional GOG model in terms of the CIEDE2000 color difference between the XYZ values of the measured color sample and the estimated XYZ values.

Published: January 2009

AbstractIn this work, we have investigated the evaluation method to quantify the phenomenon of Mura. The undulation of luminance and transmittance distribution is precisely matched to the Mura position. And by adjusting Vgh, we can distinguish the specific Mura that results from electrical variation. Additionally, transferring T% to Vdisp, Mura degree can be quantified without the noise of the test condition and traced the source clearly. Furthermore, we make criterion of dVdisp as 18mV at L16 to prevent the phenomenon of Mura.

Authors: Selbrede Martin G. 
Published: January 2009

AbstractSlab waveguides exploiting edge‐injected light enable light‐recycling backlights or provide total internal reflected light to displays that frustrate TIR. High luminous uniformity requires detuning pixel efficiencies, mirroring waveguide edges and increasing waveguide thicknesses to extend ray transits. Methods for retaining high luminous uniformity in thinner waveguides are analyzed.

AbstractA novel nanometer scaled gap in palladium thin film strip was prepared by hydrogen absorption under high pressure conditions, and implemented in the fabrication of the surface conduction electron emitter (SCE) for flat panel display applications. The lattice constant increase in the Pd due to the phase transformation from the α‐phase to the β‐phase after hydrogen absorption, a large compressive stress occurred to the Pd thin film. with a proper geometric arrangement of the Pd/Pt/Ti emitter electrode of the SCE structure, a single nanogap per SCE device was prepared. Finite element analysis was carried out to study the hydrostatic stress distribution in the thin film emitter structure after Pd hydrogenation, and thereby the optimized thickness of thin film electrodes of the emitter was determined for the nanogap fabrication. The novel SCE emitter had an inclined protrusion structure on the cathode, which greatly enhance the local electrical field and improve electron beam focusing. The experimental measurement and theoretical analysis show that field emission properties of the novel SCE are superior to conventional SCE with the coplanar cathode.

Published: January 2009

AbstractPeriodic Ag metallic nanostructures with different size, shape, and line pitch on ITO/glass substrates have been fabricated by using electron‐beam lithography (EBL) technique for studying the color light guide in a TFT‐LCD system. Scattering ability of a nano‐Size metallic structure is depended on the surface plasmon resonance (SPR). Because of the light wave which can be diffracted by the nanostructures, and the different wavelengths will generate dissimilar first‐order diffraction angles. From this study, we have demonstrated that the back light system containing a metallic periodic nanostructure with varied line pitches can be used as a color filter in a LED device. This means that with a proper nanostructure layer, the RGB colors in a TFT‐LCD can be obtained without a traditional color filter.

Authors: Chen Yung‐Kan , Lin Mao‐Hsing , Huang Kun‐Feng 
Published: January 2009

AbstractIn this paper, we discuss the junction temperature of LED in the LCD module. The lifetime of LED strongly depends on the junction temperature. Besides, the optical performance of LED will decay with the rise of junction temperature. Mura of LCD module may occur due to non‐uniform decay of the LEDs, which are the light sources of LCD module. Besides forward current and voltage, package material, PCB and LCD module design will also affect the LED junction temperature. By using numerical analysis, we can understand the parameters that strongly affect the LED junction and improve the quality of LCD with LED backlight. Lead frame material of LED package, dielectric layer of the PCB, and the back cover of LCD module are discussed in this paper to have a good thermal performance of the LCD module with LED backlight.

13.4: Copper Nanowires with Five‐Twinned Structure Grown by Chemical Vapor Deposition and their Application to Field Emission Displays
Authors: Kim Changwook , Choi Hyungsoo , Kim Kyekyoon (Kevin) 
Published: January 2009

AbstractA prototype field emission display device was fabricated using copper nanowires as emitters. The copper nanowires were grown by chemical vapor deposition without any catalyst or template, which were analyzed by electron microscopy to show a five‐fold twinned structure with a pentagonal pyramid tip. The electron diffraction pattern disclosed that the twin boundaries were mismatched irregularly. The anisotropic growth of the copper nanowires in gas phase could be attributed to the passivation of the {100} side planes by the phosphite molecules dissociated from the precursor. Field emission characteristics of the nanowires were measured.
P‐122: Characteristics of Low‐Pressure Cold Cathode Fluorescent Lamp for Brightness Uniformity
Authors: Park Yong‐eun , Kim Heung‐Seok , Yoon Sang‐hyuck , Um Jae‐eun , Park Jin‐ho 
Published: January 2009

AbstractIn this paper, we describe the characteristics of Low‐pressure Cold Cathode Fluorescent Lamp for the uniformity of brightness. Cold Cathode Fluorescent Lamps are key parts of the TFT‐LCD display devices. The most commonly used lamps for the backlight units have a brightness overshoot phenomenon for the beginning of turn‐on time. Main reason for this artifact is widely known that plasma ions conflict strongly in the lamp having high gas pressure. In this paper, we have studied how much pressure is good for the brightness uniformity and how much gas pressure doesn't effect the life time and brightness of the lamps. There are three factors for the best brightness uniformity — Lamp, diffuser plate and BLU design of having heat‐Sink function. We show the experimental results of the relations of lamp pressure and brightness. And we suggest how we can find out the best method for the brightness uniformity of BLU.

P‐128: Experimental Study on Reduction of Temporal Bright Image Sticking in AC‐PDP Using Vacuum‐Sealing Method
Authors: Park Choon‐Sang , Tae Heung‐Sik , Kwon Young‐Kuk , Heo Eun Gi 
Published: January 2009

AbstractThe base vacuum level before filling a discharge gas is an important parameter to affect both the temporal dark and bright image stickings in an AC‐PDP. In this paper, the vacuum‐sealing method is adopted to minimize the residual impurity gas by enhancing a base vacuum level, and the resultant change in the temporal bright image sticking was examined in comparison with that of the conventional sealing method in the 42‐in. ac‐PDP with a high Xe (11 %) content. As a result of monitoring the difference in the display luminance and infrared emission between the cells with and without temporal bright image sticking, the vacuum‐sealing method can reduce the temporal bright image sticking which is caused by decrease in the residual impurity gases and an increase in the oxygen vacancy of the MgO layer. In particular, in the vacuum‐sealing method, the modified driving waveform enabled the effective reduction of temporal bright image sticking.
