P‐65: FLOATS V: Real‐Image‐Based Autostereoscopic Display with TFT‐LC Filter
Authors: Kakeya Hideki 
Published: January 2005

AbstractThe author proposes FLOATS V: a real‐image‐based autostereoscopic display with a TFT‐LC filter. FLOATS is an autostereoscopic display technology which combines generation of floating real image and parallax presentation to show realistic 3‐D image within the viewer's reach. Earlier versions of FLOATS have used mechanical control of filters to keep on showing different images to each eye when the head of the viewer moves, which has often caused disturbances of stereoscopic views in case of fast motion or large inclination of the viewer's head. The system proposed in this paper uses an electronic LC filter instead of mechanical filters and succeeds in overcoming the problems of conventional FLOATS mentioned above.
P‐68: Numerical Optimization of Heat Sink Configuration for Avoiding Sound Noise Resonance in PDP PCB
Authors: Cho Insoo , Lee Seokyeong , Kim Seoksan 
Published: January 2005

AbstractPDP module mainly consists of panel and circuitries. Sound noise level in PDP module's rear side is relatively high rather than that in front side. It is due to sound noise caused from PCBs placed on rear side of PDP module. To analyze sound noise source and reduce sound noise level on PCB's of PDP module. Current wave form, voltage wave form and FFT spectrum are examined by oscilloscope and spectrum analyzer for PCB driving circuit board. Vibration frequency is measured by vibration sensor for parts on PCBs. It is found that peak frequency taken place from driver circuitry PCBs is as same as that of vibration on heat sink connected to MOSFET chip for heat dissipation of MOSFET chip on a PCB. Heat Sink is generally composed of aluminum metal and is also made large in height and area of heat dissipation to remove much more heat originated from MOSFET chip which is small in size on PCBs. Resonance noise between MOSFET chip and heat sink is enlarged much more through heat dissipation area of heat sink with a number of aluminum thin plate. Here, numerical approach of heat sink configuration is performed to avoid resonance frequency and reduce sound noise level on rear side of PDP module.
P‐70: New Long Gap Discharge Mode Driven by Low Sustain Voltage for Highly Efficient Plasma Displays
Authors: Kim Hyun , Kim Jae Young , Tae Heung‐Sik , Seo Jeong Hyun , Lee Seok‐Hyun 
Published: January 2005

AbstractThis paper proposes a new long gap discharge mode with a long gap of 400 μm driven by a low sustain voltage (< 200 V) for a highly efficient three‐electrode alternate current plasma display panel (ac‐PDP). Two different types of long‐gap discharge modes can be created depending on the voltage distribution among the three electrodes: a forward long gap discharge mode (FLGDM) with a high sustain voltage where the discharge is initiated from the voltage‐supplied electrode, and a reverse long gap discharge mode (RLGDM) with a low sustain voltage where the discharge is initiated from the ground electrode. As such, in the current study, a highly efficient discharge mode in a long gap was efficiently constructed under a low sustain voltage by properly controlling the amplitude and width of the auxiliary short pulse applied to the address electrode, resulting in a reverse long gap discharge mode with a high efficiency of 2.5 lm/W at a sustain voltage of 170 V.
P‐72: Effect of Additional Pulse on the Addressing Period for Improving the Addressing Time in AC PDPs
Authors: Lim Jong‐Sik , Kim Hyun‐Seok , Kim Joon‐Yub 
Published: January 2005

AbstractWhen the ADS driving method is applied to the high‐resolution AC PDP, the required long addressing time often becomes a problem. In this paper, a new waveform for the improvement of the luminance and the stable addressing discharge is presented. In this new waveform, a wall charge acceleration pulse is applied to the common electrode right after addressing discharge. In this way, the charge generated by the addressing discharge is accelerated to the electrodes. Experiments using the wall charge acceleration pulse showed that we could stably address an AC PDP with the scan pulses having pulse width of 1us.
P‐73: A New Gray‐scale Driving Method in an AC Plasma Display Panel
Authors: Kim Jae‐Sung , Hwang Hyun‐Tae , Kim Sung‐Hwan , Kim Gun‐Su , Lee Seok‐Hyun , Seo Jeong‐Hyun 
Published: January 2005

AbstractIn this paper, a new gray scale expression method that divides scan lines into multiple blocks is suggested. The proposed method can drive 16 sub‐fields per 1 TV field in the panel with XGA (1366×768) resolution. Because reset pulse is applied every 2 sub‐fields, both the contrast ratio and the dynamic voltage margin are sufficiently obtained in comparison with previous AWD (Address While Display) methods. In realizing 16 subfields, shortening the scan time in the erase address period was important. The X bias voltage in the erase address period affected the minimum address voltage but did not the delay time of address discharge. The delay time of address discharge was affected by the address voltage and the time interval between the last sustain discharge and the scanning time. We also evaluated the dynamic false contour. New method shows an improved image quality in horizontal moving, but discontinuous lines were observed at the boundaries of each block.
P‐74: A Study of the Addressing Discharge Change for the Ramp Pulse in ac Plasma Display Panels
Authors: Kwon Shi‐Ok , Lee Jea‐Kyung , Hwang Ho‐Jung 
Published: January 2005

AbstractIn this study, a new driving method is suggested to improve the luminance efficiency and the luminance. We applied a ramp pulse, instead of a square pulse, to an address period in Address Display period Separated, for operating on the Plasma Display Panels, which used the conventional gas [He‐Ne‐Xe]. When the ramp pulse is applied to the address period, improvement of the luminance and the luminance efficiency, and discharge response time was decreased. Additionally, infra red ray emission and discharge current were almost constant irrespective of the slopes of ramp pulse.
P‐76: Design of Facing Reset Discharge Waveform for Reducing Dark Image Sticking in AC‐PDP
Authors: Han Jin‐Won , Cho Byung‐Gwon , Tae Heung‐Sik , Chien Sung‐Il , Shin Bhum Jae , Kim Joon‐Yub 
Published: January 2005

AbstractThe new facing reset discharge waveform is designed and proposed to reduce a dark image sticking in AC‐PDP. In particular, the influences of two types of reset discharge (surface reset and facing reset discharges) on dark image sticking are investigated intensively. It is observed that the dark image sticking is reduced considerably when a reset discharge is produced between the scan and address electrodes instead of between the scan and sustain electrodes during a reset‐period.
P‐77: A New Measure of Dynamic False Contour in PDPs for Subfield Optimization
Authors: Eo Yoon‐Phil , Lee Sang‐Uk 
Published: January 2005

AbstractPlasma display panels (PDPs) suffer from the dynamic false contour which is the critical problem in obtaining higher picture quality. Subfield optimization technique is known to alleviate this artifact. In this paper, we propose two‐tone response as a new measure to evaluate and quantify the dynamic false contour of a subfield look‐up table (LUT). Then, we propose an effective subfield optimization technique, using the two‐tone response. Simulation results show that the dynamic false contour can be effectively reduced by the new subfield optimization algorithm based on the two‐tone response.

P‐83: Liquid Crystal Alignment on Substrates Treated with the Plasma Flux: Static and Dynamic Regimes of Irradiation

Published: January 2005

AbstractIn this paper, we present the new results related to LC alignment on the substrates obliquely treated with a “sheet” of accelerated Ar+ plasma generated by an anode layers thruster (ALT). The substrates of organic (polymers) and inorganic (glass, DLC, SiO2, etc.) origin were treated with the plasma flux in static and dynamic regime (unidirectional translation perpendicularly to plasma “sheet”). For LCs with Δ∍<0, in both regimes, we observed two aligning modes, with the easy axis confined to the plane of plasma incidence (mode 1) or perpendicular to this plane (mode 2). In the 1st aligning mode the LC pretilt angle is not equal to zero and can be varied with the incidence angle of plasma beam and the irradiation dose. The uniformity of pretilt angle is better in the dynamic regime. With the increase of irradiation dose, the alignment transition from the 1st to the 2nd mode occurs. For the LC mixtures with Δ∍<0, used for VA LCD, only the 1st mode alignment (uniform over the whole substrate) is realized. It occurs at low and even at the relatively high irradiation doses, which cause the 2nd mode alignment for the LCs with δ∍>0. The pretilt angle achieves values as high as 30° and can be controlled by the irradiation dose and by the incidence angle of plasma beam. The 2nd alignment mode is observed at high irradiation doses and only in the static regime of irradiation. It occurs in the central, most intensive part, of the plasma “sheet”, while the periphery part shows the 1st mode. The areas of the 1st and the 2nd mode are separated with the narrow transition area showing multidomain (two‐fold degenerate) LC alignment. The easy axis in these domains is turned by about ±45° with respect to the alignment direction in the 1st mode area. The alignment transition 1st mode — two‐fold degenerate alignment — 2nd mode observed for LC with δ∍<0 is quite similar to the one earlier described for vapor deposition alignment. In the dynamic irradiation regime, for both types of LC, uniform alignment on the substrates as big as 15×15 cm is realized.

Published: January 2005

AbstractPolyimide layers for homeotropic alignment can align liquid crystal horizontally after an ion beam is exposed on their surfaces in proper conditions. By exposing an ion beam on homeotropic alignment layers, we can achieve multi‐domain alignment for a hybrid‐aligned‐nematic (HAN) cell. We found that a two‐domain HAN cell achieved by the ion beam exposure shows good electro‐optical characteristics. We also point out that use of two same alignment layers in a HAN sample could reduce the cost for product and the generation of a DC offset voltage.

Published: January 2005

AbstractIn this study, we performed a three‐dimensional computer simulation for the electro‐optical characteristics of a super in‐plane switching liquid crystal displays(Super IPS‐LCDs) in a unit pixel of TFT‐LCDs, for the first time, and compared the results with experiments. The dynamic equation of continuum theory for liquid crystals is based on a tensorial formulation. As a numerical technique, we used a finite difference method(FDM) suitable for highly nonlinear equations. As a result, we confirmed that the simulation results such as a transmission profile over a pixel and an average transmittance as a function of applied voltage showed good agreement with the experimental results. We also revealed that Super IPS‐LCDs show good wide viewing angle characteristics with contrast ratio of more than 50:1 up to a polar angle of ±90° both in the horizontal and the vertical directions.

By using a small concentration of polymer we are able to stabilize two switching modes, phase‐only (in‐plane switching at low field) and birefringence (out‐of plane at high field), of the uniformly lying helix (ULH) texture of a cholesteric with a sub‐millisecond response time.

AbstractWe have fabricated dual‐domain twisted structure by imprinting of LC alignment on polymer layers during polymerizing induced phase separation in polymer and liquid crystal (LC) composite systems. By application of electric field during UV exposure, the photopolymerized polymer chains are formed along the long molecular axis of LC aligned by the field. The aligned polymer chains align LC molecules after removing the field. Using this method, we successfully fabricated dual‐domain twisted nematic structures.

And the discostic‐shaped polymer optical compensation of Fuji photo film (Super wide viewing angle film) was used for further promoting the viewing angle performance.

Published: January 2005

AbstractThis paper describes the first research prototype of color in‐plane electrophoretic display. Characteristic of optical performance is improved by incorporating an anisotropic scattering layer instead of an isotropic scattering layer. The reflectance of a white state is 35% at an illumination angle of 30° and a detector angle of 0° to the surface normal. The color coordinate does not change very much differently from the reflective LCD while changing an illumination angle from 70° to 30°.

Published: January 2005

AbstractIn this paper, it was demonstrated that the organic thin‐film transistors were fabricated with the organic gate insulator with vapor deposition polymerization (VDP) processing. The saturated slop in the saturation region and the subthreshold nonlinearity in the triode region were clearly observed in the electrical output characteristics in our organic thin film transistors using the staggered‐inverted top‐contact structure. Field effect mobility, threshold voltage, and on‐off current ratio in 0.45 μm thick gate dielectric layer were about 0.5 cm2/Vs, −5 V, and 105A/A, respectively. In order to form polyimide as a gate insulator, vapor deposition polymerization process was also introduced instead of spin‐coating process, where polyimide film was co‐deposited by high‐vacuum thermal evaporation from 6FDA and ODA followed by curing.
P‐112: Electroluminescence of Red Organic Light‐Emitting Devices Using Rubrene as an Emitting Assist Dopant
Authors: Lee Chang Min , Kim Dong Il , Han Jeong Whan 
Published: January 2005

AbstractWe present red OLEDs with improved efficiency using rubrene as an emitting assist dopant. Alq3 and α‐NPD are used as electron and hole transport layers, respectively. DCJTB and rubrene are codoped into the emitting layer Alq3 which consists of several dotted‐line doped layers. The luminance yield of the device codoped with DCJTB and rubrene is greatly improved as much as ∼90% at 1 0 mA/cm2 (6.5 cd/A: 3.44 cd/A) compared with that of the devices doped with only DCJTB. We attribute it to both the emitting assist dopant (rubrene) and the dotted‐line doped layer structures. It is observed that the difference in luminance yield between the codoped devices and the doped devices decreases gradually with increasing the numbers of dotte‐line doped layers. We have also fabricated high‐efficiency red OLEDs with or without a hole blocking layer(HBL), and observed that the luminance yields of the devices with HBL are always higher than those of the devices without HBL except for a device with 6 dotted‐lines doped layer structure in emissive region.

Published: January 2005

AbstractSynthesized were novel dioctylfluorene (DOF) and benzothiadiazole (DBT) copolymers having various contents of DBT and yielding pure red emission. Based on the copolymer only with 5% of DBT as the emitter, the external quantum efficiency is over 2.0% from the device whose structure is ITO/PVK/DOF‐DBT5/Ba/Al. The efficiency can be further improved by over 4.0% using the blend polymer of P‐PPV and DOF‐DBT(5%) on energy transfer mechanism. The red‐emitting copolymer was utilized to fabricate a matrix display which showed wonderful pictures, demonstrating that the new red efficient copolymer could be a promising candidate for practical applications.
