Published: January 2005

AbstractSealing of two glass plates composing of PDP panel was done in a vacuum chamber by using an auxiliary heating line(AHL). In order to improve the uniformity of sealing temperature and reduce the panel temperature during sealing, the AHL was introduced by a screen printing method inside a frit glass and used as a part of heating source for the frit melting. Outgassing and bubbling can be also severe problems during the heating process of the frit glass inside a vacuum chamber. Our specially prepared frit glass was successfully applied for the vacuum in‐line sealing approach without bubbles.By using the AHL technology and the specially prepared frit glass, we have successfully sealed a PDP test panel without bubbles and any leak through the frit glass.

Authors: Cornelissen Hugo J. , de Pooter Jacco A. , Braat Joseph J. M. , Wittermans Harro J. 
Published: January 2005

AbstractIn frontlights for reflective LCDs made from micro‐optically structured lightguides, unwanted shadows appear in certain viewing directions. It is shown that these shadows are wider than predicted from geometrical ray optics, and that they can not be eliminated by decreasing the micro‐optical structure size. These experimental observations can be explained accurately by taking Fresnel diffraction into account.

Published: January 2005

AbstractBy introducing Cd, a new family of oxide thin film electroluminescent phosphors is presented. EL devices using (CdxZn1−x)Ga2O4: Mn phosphors exhibit excellent green emission with peak wavelength of 504 nm, colour coordinates x = 0.8 and y = 0.69, and a peak brightness of 55 cd/m2 and an efficiency of 0.55 lm/W at 40 V above threshold and driven at 60 Hz.

Published: January 2005

AbstractA numerical analysis of the micro discharge in a PDP cell has been made using a time‐dependent 2D fluid model. We have investigated the response time, the peak time of the discharge current, after applying voltage. With increasing the gas pressure, the response times decreased under sustain voltage condition and increased under the fixed voltage condition. The response times were found to reduce as Xe or He concentration was increased. Moreover, the experimental data were found to agree well with the simulation results. These results offer the possibility of reducing addressing or sustaining times.

Authors: Cho Byung‐Gwon , Tae Heung‐Sik , Chien Sung‐Il , Lee Seok‐Hyun , Kim Joon‐Yub 
Published: January 2005

AbstractIn this paper, a new driving scheme is proposed to improve the luminous efficiency using a self‐erasing discharge during a sustain‐period in an AC PDP. The self‐erasing discharge is produced between successive sustain pulses by simultaneously applying the short address pulses at the falling edge of the sustain pulses, thereby resulting in improving the luminous efficiency without reducing the luminance. It is found that this new driving scheme can improve the luminous efficiency by 37.5 % and the luminance by 3.5 %, when compared with the conventional driving scheme of an AC PDP.
P‐65: White Color Balancing using New Luminance Compensation Driving Method in AC PDP
Authors: Jang Sang‐Hun , Cho Ki‐Duck , Tae Heung‐Sik , Chien Sung‐Il , Jeong Dong‐Cheol , Whang Ki‐Woong 
Published: January 2005

AbstractThe new driving method is proposed based on the luminance compensation against subfield variation for balancing the white color in an AC PDP. The luminance ratio among the red, green, and blue light can be controlled independently by applying the different auxiliary address pulses to the red, green, and blue cells during a sustain‐period. As a result, the minimum perceptible white color difference (Δuv < 0.002) with respect to the reference white color at SF5 is obtained irrespective of the variation in the subfield from SF1 to SF8.

P‐66: Influence of Azimuthal Anchoring on Bistable Behaviors of Bistable Nematic Liquid Crystal Cells
Authors: Tsuchida S. , Chiba T. , Udagawa M. , Takahashi T. , Saito S. 
Published: January 2005

AbstractA theoretical expressions are devived for a range of the d/P0 ratio in which two distinct states exist in the equilibrium condition and the lower limit of azimuthal anchoring energy exhibiting two distinct states. Theoretical calculations have been made on the bi‐stable energy curve which has two minimal energy levels corresponding to bi‐stable states. It has been shown that the energy barrier between the two states mainly originates from the azimuthal anchoring energy and the height of the energy barrier is affected by the d/P0 ratio and cell thickness.

Authors: Park Won Sang , Jhun Chul Gyu , Kang Jin‐Woo , Choi Duk Woon , Han Kwan Young , Yoon Tae‐Hoon , Kim Jae Chang 
Published: January 2005

AbstractExperimentally, the propagating fingers are observed distinctly under triangular AC pulse, but not under waveforms for gray scale such as SWBR (selection voltage‐well bias reset) and SBR‐AC (selection bias reset signal AC). Therefore, many researchers don't accept yet that the gray scale in AFLCs is obtained as a mixture of switched and unswitched areas. So, we have investigated the switching of AFLC under waveforms for gray scale by means of CCD camera pictures and electro‐optic measurements. From our experiments, we have proved that the propagating fingers appear as the form of a delayed reponse time under waveforms for gray scale and the delay time makes possible to perform the gray scale under passive matrix driving in the high resolution condition which the selection pulse width is shorter than it's response time.
P‐78: Geometrical Optics Approach for LCDs with Three Dimensional Director Variations
Authors: Panasyuk G. , Kelly J. , Allender D. W. , Gartland E. C. 
Published: January 2005

AbstractThe geometrical optics approach (GOA) is applied to the propagation of light through liquid crystal films whose director varies in three spatial dimensions. As an example of application, the GOA is applied to the calculation of light transmittance for the case of a LCD cell which exhibits the homeotropic to multidomainlike (HMD) transition. Comparison with Jones calculus is also provided. For smaller geometries, where the Jones calculus breaks down, the GOA provides a fast, accurate method for calculating the optical performance of LCDs.

Published: January 2005

AbstractWe studied the optical performance of reflective wire grid polarizer designed for visible light. The polarizer reflects E‐polarization and transmits H‐polarization with low losses. When used in a twisted nematic (TN) device as a back polarizer it enhances the brightness and provides high contrast ratio at wide viewing angles. By placing the wire grid polarizer within the cell, viewing parallax is eliminated. The polarizer can also be used as the rear electrode.

Authors: Choi Wing‐Kit 
Published: January 2005

AbstractA simple technique of measuring a reflective TN liquid crystal (LC) cell gap using a laser is described. It utilizes a very unique property of strong input‐polarization‐angle dependence of the reflective LCs, which is not observed in the conventional transmissive LCs. This technique eliminates the surface‐reflection problem which can be encountered by most other techniques using a monochromatic light source. Quantitative experimental results obtained have confirmed the validity of this scheme.

P‐90: Tailoring Morphology in Holographic‐Polymer Dispersed Liquid Crystals for Reflective Display Applications
Authors: Escuti Michael , Crawford Gregory 
Published: January 2005

AbstractIt is well known that the electro‐optics of holographic‐polymer dispersed liquid crystal (H‐PDLC) materials are critically dependent on the phase separation dynamics and the final polymer morphology. We therefore demonstrate and explore how multiple‐beam holography can be used to produce three‐dimensional arrays of LC droplets and characterize their effect on the electro‐optical properties of the reflection from these switchable films. We have exhausted many avenues to improve these materials in the context of reflective display applications and have found that this approach represents a novel way to beneficially modify the formation process.

P‐96: Experimental Measurement of Cauchy Values for Δn of Nematic Liquid Crystals
Authors: Gandhi Jignesh , Anderson James E. 
Published: January 2005

AbstractRefractive indices of liquid crystal materials change dramatically with the wavelength of light due to dispersion. The Cauchy formula provides an empirical way of describing the relationship of various refractive indices of liquid crystal with wavelength of light. It is often difficult to measure individual refractive indices (ne and no) at several wavelengths and hence the birefringence Δn. In most liquid crystal device simulations, it is important to know Δn as a function of wavelength for accurate performance prediction. Here we propose a simple method of measuring Δn of liquid crystalline materials at various wavelengths and obtaining the Cauchy values for the LC material.
