Published: January 2005

AbstractPolycrystalline silicon (poly‐Si) thin‐film transistors (TFTs) were fabricated with a dual‐layer gate dielectric of electron‐cyclotron resonance (ECR) oxide and plasma‐enhanced chemical vapor deposited (PECVD) oxide, with a maximum process temperature of 150°C, using excimer laser annealing. We demonstrate effective carrier mobilities > 90 cm2/Vs, threshold voltage < 10V and breakdown voltage > 35 V. These are the best results reported to date for any TFT technology compatible with polyester substrates.
30.4: Short‐Channel Effect of Sub‐Micron Poly‐Si TFTs with Large Poly‐Si Grains
Authors: Akimoto H. , Hatano M. , Sakai T. 
Published: January 2005

AbstractTo study 3 V‐driven LSI‐like TFTs, we fabricated high‐temperature n‐channel poly‐Si TFTs, some of which had a subthreshold slope of 90 mV/dec and an electron field mobility of 432 cm2/Vs, with submicron channel length and large poly‐Si grains. We only observed an anomalous parasitic bipolar transistor effect in the TFTs with good trans‐conductance, and concluded that the grain‐boundary affects the trans‐conductance severely than the threshold voltage and the subthreshold slope.

A Study of the Dynamics of Reflection Color, Helical Axis Orientation, and Domain Size in Cholesteric Liquid Crystal Displays
Authors: Watson P. , Sergan V. , Anderson J. E. , Ruth J. , Bos P. J. 
Published: January 2005

AbstractThe relaxation from the field‐induced homeotropic state to the equilibrium planar state of cholesteric liquid crystals is investigated. By using an optical retro‐reflection technique, we have isolated the dynamics of the orientation and pitch of cholesteric helices, and through scattering and microscopy techniques, we have determined domain size as a function of time for various surface treatments. These three factors determine the viewing angle, color, and brightness of a display. An analysis of the significance of surface selection in cholesteric displays is presented.

AbstractWe improved the parallax barrier technology to solve some peculiar problems to 3‐D displays with no special glasses, for example darkness of the parallax barrier, moire arising from the interference between the pixel of the LCD and the parallax barrier, crosstalk of the two binocular images and further reduction of the resolution when displaying 2‐D images. This paper introduce our those improved technologies of the 3‐D displays, one of which has a compatibility with the 2‐D display. and this paper also introduce a conversion technology of 2‐D images into 3‐D images. Those technologies will expand the field of application of the 3‐D displays.

Authors: Morishama H. , Nose H. , Taniguchi N. , Inoguchi K. , Matsumura S. 
Published: January 2005

AbstractWe have developed a new method of an eyeglass‐free stereoscopic display, which we call “Rear‐Cross‐Lenticular 3‐D Display” (RCL3D). The RCL3D consists of a LCD panel, two lenticular lens sheets which run perpendicular to each other, a Checkered Pattern Mask and a backlight panel. On the LCD panel, a composite image which consists of alternately arranged horizontally striped images for right eye and left eye, is displayed. This composite image form is compatible with the field sequential stereoscopic image data. We made prototype of the RCL3D (14.5″, XGA) and confined the good quality of the stereoscopic 3‐D images. But there is slight crosstalk with the prototype. The measured crosstalk is around 5%. According to the results of a simulation of illumination profile in viewing zone, LCD with less reflectance and scattering is expected for RCL3D to reduce the crosstalk.
33.2: Viewing Angle: A Matter of Perspective
Authors: Fiske T. G. , Silverstein L. D. , Penn C. , Kelley E. F. 
Published: January 2005

AbstractSetting viewing‐angle requirements and specifications for displays depends on how viewing‐angle is defined. There is significant confusion in the industry regarding the definition and use of horizontal and vertical viewing‐angle. Moreover, the relations between viewing‐angle defined in Cartesian coordinates and common representations in spherical and goniometer‐specific coordinates are often confused. This paper will show how incorrect definitions of viewing‐angle and failures to apply appropriate transformations between coordinate systems lead to errors in setting specifications and reporting results.
33.3: Small‐Area Black Luminance Measurements on White Screen Using Replica Masks
Authors: Boynton P. A. , Kelley E. F. 
Published: January 2005

AbstractLuminance measurements of small areas of black pixels on white‐screen backgrounds are often used as metrics in display measurements, such as character‐stroke contrasts or deep modulation transfer functions. Serious errors may be made in measurements and subsequent ergonomic conclusions if glare contributions of the measurement are not considered. We show a simple method for accounting for glare corruption of luminance measurements by using replica masks.
Reflection Measurement Problems Arising from Haze
Authors: Jones George R. , Kelley Edward F. 
Published: January 2005

AbstractIrreproducibility in some reflection measurement methods arises from the observance of the haze component of reflection (non‐regular‐specular, non‐Lambertian). Because of the haze component, the measured reflection is sensitive to the apparatus configuration. We show the effects of detector lens aperture and detector distance on the measurement of the reflected luminance. Only for detectors with small subtense angles can reproducibility be assured when haze reflection is nontrivial.

35.1: Simulation Method to Calculate Effective Mobility of Pixel Switching TFT Devices for QXGA TFT‐LCD Monitors
Authors: Kawamoto S. , Kobayashi K. , Morishita M. 
Published: January 2005

AbstractA new simulation method to calculate effective mobility of pixel switching TFT devices has been developed. It is applied to high resolution TFT‐LCD monitors with a high aperture ratio and a pixel inversion driving method. Our results show that mobility greater than 1.0 cm2/v s is required for over 21 inch QXGA TFT‐LCD monitors. Therefore, it is suitable to adopt low temperature poly‐Si TFT devices for achieving QXGA TFT‐LCD monitors.
Accurate Modeling of the Dynamics of TN Devices with Flow
Authors: Jamal Syed H. , Kelly Jack R. 
Published: January 2005

AbstractWe have modeled the switching behavior of a TN cell using the one dimensional Ericksen‐Leslie equations of nematodynamics. We compare the modeling results with experimental data on the luminance versus time of a normally white twisted nematic (NWTN) cell. Excellent agreement between experiment and model is achieved at all voltages and viewing angles. To achieve this agreement, only two viscosity parameters are required; these are combinations of the Leslie viscosity coefficients, namely γ1(i.e. α3)−α2and α4)+α5. These parameters are easily determined from dynamic optical measurements of a TN cell.With an adaptive time step, the equations can be solved on a time scale that makes interactive computing possible. Combined accuracy and speed make the model useful as a device design tool. For example, liquid crystal response to different active addressing schemes could be accurately modeled, eliminating the need for costly and time consuming testbedding of different schemes.
36.4: Propagation and Optimization of Stokes Parameters for Arbitrary Twisted Nematic Liquid Crystal
Authors: Suh Seong‐Woo , Zhuang Zhizhong , Patel J. S. 
Published: January 2005

AbstractTwisted nematic liquid (TN) crystal structures have been used extensively to rotate the input polarization of the light by 90°. For optimum performance of these devices, optimization is necessary for exact rotation of linear polarization of the input light. Using Stokes parameter representation, we derive the generalized relationship, which allows the calculations of the optimum parameters necessary for arbitrary rotation of the linearly polarized light with arbitrary amounts of twist of the liquid crystal structure. We show that “Gooch and Tarry” relation is a specialized case of our generalized results.

Published: January 2005

AbstractA new class of flat panel display (FPD), the ThinCRT™, has been developed. This new technology shows promise for applications ranging from power efficient notebook computer and handheld displays to desktop monitors and televisions. A thin form factor (<8mm) has been combined with CRT visual performance in a low cost, volume manufacturable technology. This has been achieved by using a relatively high (6kV) anode voltage, low (<1O.5V) column driver switching voltages, with low resolution (>5 micron) photolithographically defined features. The construction and performance of ThinCRT displays are discussed.

Published: January 2005

AbstractRecent trends towards the wider use of high information content displays have led to the development of high resolution projection devices which image small size LCD / DMD's having a large number of pixels. The use of these microdisplays poses more stringent demands on the correction of aberrations in projection lenses. This paper addresses the image quality requirements for lenses used in front and rear projection configurations. Examples of various projection lenses for different applications are presented.

Dynamic Gray‐Scale Control to Reduce Motion Picture Disturbance for High‐Resolution PDP
Authors: Kawahara I. , Sekimoto K. 
Published: January 2005

AbstractA new approach is presented to reduce motional false contour artifacts, or motion picture disturbance, in ACPDP by dynamically controlling usable gray‐scale levels. Limited gray‐scale levels are selected to form astretched‐out coding, which is used in motion area where the disturbance could be visible. A disturbance‐free condition in the stretched‐out coding is discussed and verified through the simulation with virtual retina model. Gray‐scales in motion area are substantially restored both by error diffusion based on Floyd and Steinberg, and by response of human vision combined with subfield driving sequence. The algorithm, also being compatible with the highest HDTV standard with resolution of 1920 × 1080 progressive, just requires simplified motion detection without motion vectors. The actual 42‐in PDPs with this algorithm using 10 subfields showed robust and better performance over conventional approaches.
Shortcomings of the Q Tensor Method for Modeling Liquid Crystal Devices
Authors: Anderson J. E. , Watson P. , Bos P. J. 
Published: January 2005

AbstractBecause writing the free energy in terms of the order parameter tensor, Q, maintains the equivalence of n and −n, while writing it in terms of the director, n does not, it has been thought that the tensor approach was more correct. We found that this equivalence can cause a simulation to transform between topologically inequivalent states without a wall disclination, a non‐physical situtation. The reasons usually given for using the tensor method thus must be flawed when simulating devices. Because the vector approach is also mathematically simpler, computationally faster and requires fewer grid points, it is the suggested simulation method.

Electronic Cinema Using ILA® Projector Technology
Authors: Sterling R. D. , Bleha W. P. 
Published: January 2005

AbstractThe use of video for the replacement of 35mm film presentation Electronic Cinema offers many potential advantages in the production, distribution, and exhibition of motion pictures. A key enabling component for Electronic Cinema is the video projector which must provide the image quality and brightness required to replace film projection in a theatre venue. New ILA® projectors have been developed to meet these stringent requirements. ILA® projectors provide up to 17,000 lumens, greater than 2000 TV lines of horizontal resolution, and over 1500:1 sequential contrast ratio. The unique ILA® device design has no pixel structure so that film‐like images are projected. This paper will discuss these requirements for electronic cinema and review ILA® projector technology and performance.
Ultra Fine Aperture Grille for CDTs
Authors: Makita A. , Komatsu T. , Fujiyama K. , Ishii Y. , Hashimoto D. 
Published: January 2005

AbstractA new method for producing ultra fine aperture grilles for CDTs has been developed. This new approach can produce 0.125mm pitch aperture grille for 21‐in 200‐dpi ultra fine CDTs while providing the same optical transmittance and white uniformity as those of conventional ones. Good narrow aperture performance is combined with an excellent smoothness of grille edges. This technology also allows a range of finer pitch shadowmasks as well as aperture grilles to be made practical for further high resolution CDTs.

5.2: Using an OCB‐Mode TFT‐LCD for High‐speed Transition from Splay to Bend Alignment
Authors: Koma N. , Miyashita X. , Uchida T. , Yoneda K. 
Published: January 2005

AbstractField sequential color LCDS require an LC‐mode with a fast response time. For this purpose, we have studied an OCB Optical Compensated Birefringence mode that is capable of displaying a gray‐scale with high‐speed response. However, this mode exhibits a splay alignment at initial state. It requires transition from the splay alignment to bend alignment before drive, while it takes a relatively long time in general. To solve this problem a new method is proposed. It employs an optimized TFT‐array structure with a low‐temperature p‐Si TFT‐LCD and a high DC voltage is applied to a common electrode at initial state. This new method enable the initial transition to be less than 3 sec and no defective pixel remains.
