P‐41: 1.6Gbps Low‐Power Receiver for Display Interfaces Using a 3.3V and 0.35μm CMOS Process
Authors: Kim Jin‐Ho , Kwon Oh‐Kyong 
Published: August 2007

AbstractThis paper proposes a low‐power receiver circuit that converts 1.6Gbps low‐voltage differential input signal with less than 100mV swing to CMOS level signal in a 0.35μm CMOS process. The proposed receiver enhances its bandwidth with low power consumption using the negative feedback circuit which is detecting input signal transient. HSPICE simulation results show that the power consumption of the proposed receiver at 1.6Gbps data recovery is less than 4mW, and the maximum jitter for 9‐bit PRBS input pattern is less than 10% of bit‐time. Compared to the previous LVDS receiver circuits, the proposed receiver can save more than 40% of power. In addition to the low‐power consumption, the proposed receiver has rail‐to‐rail input common‐mode voltage range.
P‐193: EMI Reducing Techniques for Low Voltage Differential Signaling by Applying a Vertically Differential Method and Data Arrangement Optimization
Authors: Takagi Ayako , Baba Masahiro , Okumura Haruhiko 
Published: August 2007

AbstractWe developed EMI (Electromagnetic Interference) reducing techniques that utilize a Vertically Differential EMI suppression method (VDE) and data arrangement optimization for Low Voltage Differential Signaling (LVDS) transmission lines. This method utilizes the vertical correlation of two adjacent horizontal lines for image data. It enables data signal frequencies below half of clock signal frequency and makes reverse phase between neighboring differential pair lines. The novel technique reduced EMI by 8 dB for a 20.8‐inch ultra‐high resolution monitor.

Published: August 2007

AbstractIn this work, wet corrosion behavior of RF magnetron sputtered molybdenum thin films was studied using by electrochemical analysis. The effects of deposition parameters such as RF power and argon pressure on corrosion rate are also examined. The corrosion rate strongly depends both on the process parameters and the type of chemical solutions. Mo thin film dissolves fastest in the nitric acid solution among the various solutions. The dissolution rates increased with increasing RF power but decreased with argon pressure. The relationship between deposition parameter and corrosion rate was discussed in terms of thin film microstructure and susceptibility of corrosion.
P‐54: Effect of Residual Stress on Mechanical Properties of PDP Glass Substrate
Authors: Hwang Jonghee , Lim Tae‐Young , Kim Nam‐Sok , Kim Hyungsun 
Published: August 2007

AbstractWe analyze the effects of thermal mismatch caused by the thermal expansion difference between the dielectric layer and the glass substrate on the breakage of PDP panel. The residual stress and the flexural strength of dielectric layer coated glass substrate were measured with the variation of thermal expansion coefficient of dielectric layer by the addition of ceramic filler. The result of strain viewer suggests that the residual strain of glass substrate near the dielectric layer showed the increase of tensile strain and the other side of the glass showed that of compression strain as the thermal expansion coefficient of dielectric layer decreased. The flexural strength of dielectric layer coated a glass substrate was also influenced by the variation of the thermal expansion coefficient of dielectric layer. The result of the analysis has shown that the thermal mismatch caused by the thermal expansion coefficient difference between the dielectric layer and the glass substrate had an effect on the residual stress and strength of glass substrate, although the thickness of dielectric layer was only a few tens of micro‐meter.

P‐74: A Reflection‐Based Printing Dot Pattern for LED Backlights
Authors: Chen Chih‐Kuang , Tsai Shau‐Yu , Lin Richard H. W. , Chi Solomon W. S. 
Published: August 2007

AbstractThe printing dot pattern on diffuser plate is utilized for thin direct LED backlight and large LED pitch. Through the reflection of printing dot pattern, the light energy is redistributed and therefore the vertical and horizontal dark bands between LED arrays can be removed. Thinner LED backlight and larger LED pitch could thus be attained. Without using any external optical lens, this backlight structure does not suffer from extra optical interface loss. Furthermore, the luminance at normal direction of this LED backlight is kept the same as the conventional one.

Published: August 2007

AbstractThis paper presents thermally adaptive driving (TAD) technology for response time compensation (RTC) of an LCD with an integrated sensor. The TAD is comprised of analog sensor signal conditioning and a digital feedback algorithm. The integrated thermal sensor provides accurate temperature measurement of the liquid crystal layer. The TAD controller has an 8‐step look‐up‐table (LUT), and compensates response time based on the panel temperature. The TAD system reduces response time by nearly 50% over the temperature range 0 ° −; 60 °C.
P‐83: A Novel Red Phosphor for Solid‐state Lighting Applications
Authors: Kang Seung‐Youl , Lee Dong Joo , Ryu Young Gi , Kang Seong‐Gu 
Published: August 2007

AbstractWe have developed a novel red phosphor based on a layered perovskite structure, Ba(La1−xEux)2Zr3O10. This phosphor showed the red photoluminescence between 580 nm and 630 nm with several excitation bands, which were composed of the charge‐transfer band related with the host matrix (around 290 nm) and the 4f ↔ 4f transitions of Eu3+ ions (between 350 nm and 460 nm). Since this excitation band is very close to the blue (around 465 nm) or near‐UV (around 400 nm) wavelengths of GaN based LED, it is expected to be used as a complementary phosphor in the red region for the white LEDs.

Published: August 2007

AbstractIn a plasma display panel (PDP), it is demanded to reduce the manufacturing cost as well as to improve luminous efficacy. Thus, high efficient ITO‐less PDPs are necessary. In this work a three‐dimensional fluid simulation is adopted to analyze the discharge phenomena of various ITO‐less structures in neon‐xenon gas mixture. The density of Xe 3P1 is investigated for the variation of electrode shapes and UV distributions on the phosphor surfaces are calculated for the 147 nm and the 173 nm. In order to investigate time and space resolved discharge physics, four structures of bus electrodes are proposed. The highest luminance efficacy was obtained with Pi structure among the proposed ITO‐less structures.
P‐94: Selective Reset Driving in Plasma Display Panel with a Sustain Gap of 250μm
Authors: Song Tae‐Yong , Kim Ji‐Yong , Sun‐Kim  , Kim Dong‐Hun , Lee Seok‐Hyun , Seo Jeong‐Hyun 
Published: August 2007

AbstractA selective reset waveform which can improve the dark room contrast ratio in a large sustain gap structure is suggested in this paper. When conventional selective reset discharge is performed, frequent unexpected misfiring happens because of high Vxb and much quantity of negative wall charges formed on Y electrode during final sustain period. The misfiring between sustain electrode and address electrode can be removed by lowering Vxb value and the misfiring between address electrode and scan electrode can be prevented by decreasing negative wall charges which were formed on Y electrode by applying narrow pulse voltage Vey and Vea after the last sustain pulse. When the selective reset waveform has one time reset per 8 subfields, black luminance of 1.55 cd/m2 can be obtained without any misfiring.
P‐204L: Late‐News Poster: Analysis of Statistical Time Lags Based on Wall Charges Prior to Address Discharge Using Vt Close‐Curve Method for Full‐HD AC‐PDP
Authors: Park Hyung Dal , Kim Jae Young , Tae Heung‐Sik 
Published: August 2007

AbstractThe high speed address is an important parameter to lower cost technology for the realization of full HD‐PDP. The wall charge supplied from the reset period is an important factor for affecting the fast and stable discharge characteristics during an address period. It is found that as the voltage level of the negative falling ramp in the reset waveform is lower, the accumulated wall charges during the ramp‐up period are more erased, thus reducing the amounts of wall charges prior to address discharge. The resultant changes in the address discharge characteristics were examined in the 42‐in. ac‐PDP with a high Xe (11 %) content. In particular, the measured Vt close‐curves and corresponding IR emission profiles show that less amounts of wall charges prior to an address discharge induce the decrease in the statistical time lag and total address discharge time lag in address period, thereby resulting in the stable and fast addressing. Therefore, it is advantageous to use the electric field from the applied voltage during an address discharge instead of utilizing the wall charges from the reset period for the stable and fast addressing.
P‐108: Birefringence Dispersion of Polymer Films As Applied to Optical Compensation in LCD
Authors: Greener Jehuda , Rao YuanQiao , Elman James F. 
Published: August 2007

AbstractMinimizing color shift effects in a liquid crystal display (LCD) requires close attention to the optical dispersion of compensation layers used to increase the contrast ratio and viewing angle of the display. This paper describes our attempt to systematize and characterize the birefringence dispersion of solvent‐cast polymer films and relate it to the “native” out‐of‐plane birefringence (Δnth) of the polymer and its structure. Results for a wide range of polymers show general correlation between the dispersion parameter DPΔn [≡Δn(450)/Δn(590)] and Δnth. for all positively birefringent polymers, DPΔn is always > 1, suggesting “normal” dispersion at any level of Δnth, while for negatively birefringent polymers DPΔn > 1 only when |Δnth| > ∼0.003. Below this critical value, DPΔn < 1, i.e., the polymer is reverse‐dispersive. The results are explained in terms of the Cauchy coefficients for the corresponding polymers, and they suggest that the dispersion of birefringence cannot be controlled independently of the birefringence of the polymer film.

Published: August 2007

AbstractHow the alignment and optical properties of liquid crystal polymer (LCP) film, formed by photo‐polymerization of reactive LCs, are affected by the alignment layer (AL) structure, the LC‐aligning method, and the polymerization conditions has been investigated. It has turned out that the alignment characteristics of LCP film greatly depend on the nature of AL and the polymerization condition and that its optical properties are governed by the degree of the in‐plane alignment of LC molecules. In the case of in‐air photo‐polymerization, a higher intensity of UV irradiation at a fixed exposure dosage has induced the higher degree of polymerization of LCP film and thus the better thermal stability than a lower intensity. The rubbed AL has induced the higher degree of the in‐plane alignment, with the tilted optic axis, and subsequently produced the better optical properties. On the other hand, photoalignment has generated the inferior LC alignment, with no tilt of the optic axis, indicating its low capability for aligning LC molecules.

Published: August 2007

AbstractNew principal for LCD modeling is proposed. We developed a real‐time simulation software based on fast algorithms for solving differential equation. Rapid calculation of LC structure allows the change of electrooptical response to be seen immediately after changing any parameters of liquid crystal or cell configuration. The software is useful for fitting the measured parameters related to LC materials and device and for device optimization. To demonstrate the power of this software, transmittance voltage dependences were simulated and relaxation time optimizations were carried out. Our rapid algorithm can be used for dynamic driving simulations and overdrive optimization as well.

Published: August 2007

AbstractWe have developed a novel transflective liquid crystal display (TRLCD) that uses a specific pixel structure and Multi‐domain Vertical Alignment (MVA) for driving liquid crystal cell with normal black operation under single cell gap. This structure can provide two individual driving gammas for both transmissive and reflective mode. Due to the single cell gap, it can simplify the fabrication process and obtain the higher contrast ratio. Liquid crystal molecules will reveal much better alignment because of the uniform strength by utilizing the square pixel structure.

Published: August 2007

AbstractWe proposed the wide‐viewing‐angle liquid crystal display (WVALCD) of the patterned vertical alignment (PVA) mode by adopting differential geometry of the electrode pattern. Due to the patterned electrode structure, we can obtain 8‐domain LC alignment in a simple fabrication process while the conventional PVA mode has only 4‐domain structure. This multi‐patterned electrode technique enlarges the viewing angle of LCD about 12% compared to the conventional PVA mode.
P‐148: Viewing Angle Switching in Vertical Alignment Liquid Crystal Display by Optimizing Pixel Structure and Controlling LC Orientation

Published: August 2007

AbstractViewing angle control of a vertical alignment (VA) liquid crystal display using only one panel has been investigated. In conventional VA modes, LC director tilts down in four directions making 45° with respect to crossed polarizers to give rise to wide viewing angle. By dividing pixel into two regions or RGBW structure and controlling the LC director to tilt down to the polarizer axes, the image quality in oblique directions can be controlled without distorting the image quality at normal direction. Also using light leakage in oblique directions, any type of information such as characters and image can be generated. This generates extra image over a main image in oblique viewing directions, that is, the original image is overlapped with made image when the voltage is controlled to the extra pixel for viewing angle control.

The LEL architecture offers significant improvement in efficiency and voltage compared to conventional phosphorescent OLEDs with carbazole‐based hosts. Further voltage reduction in our PHOLEDs is achieved through use of a novel material formulation in the ETL and EIL.

Published: August 2007

AbstractWe present a bottom‐up method of fabricating microlens arrays based on a template of close‐packed microvoids created by self‐assembly and subsequent evaporation of condensed water droplets on the surface of a polymer solution exposed to humid air. The pattern of microvoids is transferred to an optically transparent, thermally curable elastomer to form the microlens array. The method offers advantages over conventional top‐down microfabrication approaches in terms of easy fabrication, high fill factor, and near‐optimum shape of the microlenses. Attachment of the microlens array to the glass substrate of an OLED device results in a significant increase in total emission and external quantum efficiency. These experimental results are compared to the predictions of a hybrid ray optics/wave optics model that can be used to gain further understanding and to help optimize the system.

AbstractLED displays utilizing quantum dots (QDs) as emitters offer several key advantages over traditional OLEDs, combining the solution processability of polymers with the high efficiency potential of phosphors, all with the stability benefits of an inorganic emitter. While QD‐LEDs are at an early stage in their development, the effort toward commercialization has already led to the identification of several considerations particular to QD‐LEDs. This paper explores material and design considerations for QD‐LEDs and reports our progress in developing QD‐LEDs for information display and advanced applications.

AbstractWedge projection displays can be made economically in small quantities by machining the wedge profile on a thick sheet of cast acrylic, machining a constant thickness on a thin sheet of cast acrylic, then index‐matching the two together. The resulting panels can have smoothnesses almost as good as float glass and transparencies approaching that of plastic optical fibre. When used in reverse as a camera, panels have resolutions of 4 line pairs per millimetre and contrast ratios of 200:1.
