P‐189: Patterned Vehicular‐Window Screen for 3D Pico‐Projector Applications
Authors: Mphepö Wallen , He Justin Weijia 
Published: July 2011

AbstractTinted vehicle windows are commonly used for different applications among which are providing privacy, reducing transmitted sun light in hot climates and sometimes just for aesthetics among other uses. The herein reported work was geared towards retaining these traditional aspects of tinted vehicle windows while adding a new display aspect component for custom display applications. We applied a low cost dual purpose diffusely transmitting and diffusely reflective pattern onto a low cost PVC plastic film. This custom pattern printed film was then applied to both transparent and conventionally tinted vehicle windows glass to observe the change in image quality projected onto them using a low cost 45 lumens Liquid Crystal on Silicon [LCoS] Pico projector [1],[2] made in China. Images were observed and recorded under the same ambient light environment. The results showed significantly improved visibility on the vehicle windows augmented with our custom pattern printed film compared to those without the custom patterned film where the images were literally invisible. In addition we added a 3D projection prism screen to enable glasses‐free 3D perception for vehicle interior and exterior applications.

AbstractIn this paper, we proposed a novel photo sensing pixel circuit for a large‐area flexible e‐reader utilizing an active matrix electrophoretic display (AMEPD). The photo sensing pixel consists of only 2 amorphous Si:H (a‐Si:H) transistors to achieve light sensing, pixel switching and signal amplification functions without extra driving signals. The pixel output signal is up to 2V under illuminations of a common LED laser pointer. No degradation of the pixel output performance is observed after bending of more than 5000 times under 2cm curvature radius.

Published: July 2011

AbstractA novel driving scheme, smart power control SPC, is reported to reduce the power consumption of an AMOLED panel. SPC analyzes the range of the input data of each frame, calculates the optimum level of the power rail that drives the OLED, and varies the power rail voltage accordingly. As a result, a 30″ AMOLED consumes 20.1% less power when displaying the IEC 62087 standard movie clip.

17.2: Polymer Effect on the Electro‐Optic Properties of Blue‐Phase Liquid Crystals
Authors: Yan Jin , Wu Shin‐Tson 
Published: July 2011

AbstractPolymer effect on the electro‐optic properties of blue phase liquid crystal BPLC composites is investigated. A higher polymer concentration gives a more stable structure and faster response time, but its operating voltage is also higher. Monomer ratio also affects the stability of the polymer‐stabilized BPLC. However, hysteresis is not affected by polymer concentration but mainly determined by the host liquid crystal and chiral dopants.

Authors: Fan Chun‐Yuan , Wang Chun‐Ta , Lin Tsung‐Hsien , Yu Fang‐Cheng , Huang Tai‐Hsiang , Liu Chu‐Yu , Sugiura Norio 
Published: July 2011

AbstractThis paper investigates the voltage hysteresis effect and residual birefringence in the polymer‐stabilized blue phase PSBP, under various phase separation conditions. By curing the samples at a reduced temperature and controlling the polymeric propagation, the polymer in the blue phase formed a compact network near the surface of the electrode. The dense polymer network pinned the cubic lattice structure of the blue phase enabling it to return to its original optical isotropic state. In this manner, hysteresis and residual birefringence were suppressed from 6.3 % to 0.7 % and 0.33 % to 0.01 %, respectively. Although the driving voltage remained high, the reduction in hysteresis and residual birefringence are precisely the advancements required for the accelerating development of blue‐phase LCDs.

18.3: Rendering Digital Cinema and Broadcast TV Content to Wide Gamut Display Media
Authors: Heckaman Rodney L. , Sullivan James 
Published: July 2011

AbstractMuch more is possible in achieving brighter, more vibrant colors for a richer visual experience in emerging, wide‐gamut display media. Yet, both digital cinema and broadcast TV content fall well short of this promise. In this paper, we provide the means for realizing this promise by identifying certain memory colors e.g., green grass, red, and blue sky and rendering each independently making use of the full gamut of the display media while identifying and maintaining flesh tones to their original intent. Further, a means is provided for extending the gamut of not just wide‐gamut, but any display media by simply lowering the white point of the display.

21.1: Distinguished Paper: 120 Hz 3D Driving for AMOLED with Interleaved Scan and Emission Operation
Authors: Lee Baek‐woon , Han Sang‐Myeon , Sung Si‐duk , Ji In‐hwan , Shin Kwang‐sub , Berkeley Brian H. , Kim Sang Soo 
Published: July 2011

Abstract3D displays have required 1/240 s of scan time to properly display a stereoscopic image. In this report, a new driving method is proposed that provides 1/120 s of scan time, thus enabling higher resolution. The pixels are arranged as two groups: Even and Odd. One group performs scanning while the other group is emitting and in the next field, these roles are swapped. Therefore, the entire frame time can be used for data input, rather than 1/2 of the frame time as in the previous method.

23.2: Q‐Tensor Based Numerical Modeling of Blue‐Phase LCDs
Authors: Wöhler Henning , Becker Michael E. 
Published: July 2011

AbstractWe have developed a novel numerical modeling software for calculation of the molecular orientation within layers of liquid crystal material in the blue phase and for the optical properties of blue phase LCDs including additional optical components like polarizers and retarder sheets. The calculation of the molecular orientation within the blue phase layer is based on the Q‐tensor approach. Equilibrium and time dependent states are obtained with a relaxation method that minimizes the total energy of the system. Mutual coupling of the electrostatic potential and molecular orientation is taken into account. The geometry is mapped onto a 3d‐grid, periodic boundary conditions are assigned to the faces of the bounding box. The grid is extended on top and bottom side of the bounding box to apply suitable boundary conditions for the electric potential. The finite difference time domain method is applied to calculate reflectance and transmittance of blue‐phase LCDs with uniaxial perfectly matched layers on top and bottom sides of the bounding box to mitigate spurious reflections from the grid boundaries. The grid used for the Q‐tensor calculation is also chosen for the optics calculation.
25.2: Invited Paper: Dual Paraboloid Reflector Illumination System for Digital Cinema
Authors: Ouyang George , Li Kenneth 
Published: July 2011

AbstractIt has long been demonstrated that, besides extending the life time of UHP lamps, the Wavien patented dual paraboloid reflector DPR can also enhance the lamp brightness in the low etendue regime. As a follow‐up to our previous work we examine the possibility of extending the same DPR advantages to xenon arc lamps used in digital cinema. With ray tracing, we calculate the throughput efficiencies of a standard compound elliptical reflector used in the industry and a DPR reflector of similar size at various etendue values. The resultant efficiency/etendue curves are plotted and it is shown that, at a typical etendue value of 50 mm2*steradian for digital cinema up to 100% brightness improvement can be achieved. Another unique feature of the DPR system is that light recycling can be realized through etendue reduction by a recycling light pipe. Up to 40% recycling gain has been demonstrated with a 1:4 input/output etendue ratio. In addition, it is expected that the lifetime xenon lamps with the DPR can also be extended.
25.3: LED Array with Recycling for High‐Power Projector Applications
Authors: Li Kenneth 
Published: July 2011

AbstractLEDs are still not bright enough, compared to arc lamps, for high power projector applications. For high power applications, multiple LEDs are required to increase the total light output with the same amount of increase in etendue. Even with the use of larger imaging panels with larger etendue values, the total output of the LED projector is still not sufficient for cinema projection applications. With recycling technology, the etendue of the LED can be reduced with increased brightness. This paper describes two systems with an array of 7 LEDs with recycling, such that the combined etendue matches with standard imagers for cinema projector applications. The first system uses a single array of 7 white LEDs with up to 9,500 lumens of white light can be generated at an etendue of 70, which is the etendue value of standard cinema projector systems. A screen lumen of over 3,300 lumens can be achieved. The second system uses 3 independent arrays of 7 red, green and blue LEDs combined producing to 18,500 lumens of white light at an etendue of 70. A screen lumen of over 6,500 lumens can be achieved from a single projector. Using two such projectors with combined output of over 13,000 lumens, the system can be used in small cinema replacing xenon based system or laser based systems.

AbstractA mirasol display uses optical interference based MEMS pixels with inherent hysteresis and is therefore passively addressable with a near zero power hold state. This paper describes methods of addressing such a display including a method providing low power and fast addressing.

26.3 Design of a Low Power Consumption a‐IGZO TFT‐based Vcom Driver Circuit with Long‐Term Reliability
Authors: Jeong Hoon , Mativenga Mallory , Jang Jin , Lee Sang Gul , Ha Yong Min 
Published: July 2011

AbstractWe have designed an integrated a‐IGZO TFT‐based Vcom driver circuit with low power consumption, narrow bezel and long‐term reliability on a glass substrate. The proposed driving scheme can achieve 40% lower power consumption than the conventional driving scheme, owing to Vcom inversion. The higher mobility (> 10 cm2/ V.s) of the a‐IGZO TFTs compared to a‐Si:H TFTs allows the integration of smaller size devices in the gate driver circuitry, leading to displays with narrower bezels. AC driving of the buffer TFTs by clocking the nth and (n+1)th frame with 20 and 0 V, respectively, improves the lifetime of the Vcom driver circuit.

Published: July 2011

AbstractThe 120Hz frame inversion driving FHD LCD TV panels were fabricated without image degradations seen such as the luminance gradient and the horizontal crosstalk. The panels had the higher aperture ratio because of the wider electrode space between the pixel and common electrode than conventional S‐IPS. The novel driving method of gate‐low‐voltage‐swing was used to remove the luminance gradient and the new panel design of divided‐common‐feeding was adopted to suppress the horizontal crosstalk. These technologies were very successful to achieve the high aperture ratio in the S‐IPS panel without increase of the panel cost.
