P‐125: Wide‐viewing Twisted‐Nematic Liquid Crystal Display Using a Stamping‐assisted Rubbing Process
Authors: Na Jun‐Hee , Kim Yeun‐Tae , Hong Jong‐Ho , Koo Kyungmo , Lee Sin‐Doo 
Published: October 2010

AbstractWe developed a wide‐viewing twisted‐nematic (TN) liquid crystal display (LCD) with two bidirectional alignment layers using a stamping‐assisted rubbing process. The bidirectionally rubbed alignment layer through a stamping and peel‐off process provides the multi‐domain alignment of the LC molecules. The patterned fluorinated acrylate polymer, used as a protective layer, was produced to cover the rubbed alignment layer during the second rubbing process for the bidirectional LC alignment. Our multi‐domain TN‐LCD shows wide‐viewing characteristics that are symmetric with respect to the rubbing directions.

P‐151: Black Panel OLED Cluster with Constant Luminance, Lifetime Enhancement and Burn‐in Compensation
Authors: Hudak Andreas , Jung Matthias , Hohenschläger Kerstin , Blankenbach Karlheinz , Jentsch Michael , Kaster Gerhard 
Published: October 2010

AbstractOur new black panel technique for OLED displays and signs significantly improves the sunlight appearance. Additionally with our new method a better transmission of the light being coupled out of the OLED is reached. This better transmission leads to lower power consumption as well as to an enhanced lifetime of the OLED. Furthermore the lifetime of our system is increased by a constant luminance drive. This operating mode also compensates burn‐in effects that can occur if multiple OLEDs are driven for different times.

Published: October 2010

AbstractWe demonstrate efficient white top‐emitting organic light emitting devices (WTOLEDs) with Al/ITO bilayer anode with which the sputtered‐ITO thin layer is found to improve hole injection into the organic hole‐transport layer. In addition, by capping with a transparent organic layer of NPB (n ∼ 1.6) on the semitransparent cathode to suppress the undesirable microcavity effect, a broadband white emission can be achieved. The WTOLEDs with two adjacent fluorescent blue/yellow emissive layers can achieve an EL efficiency of 13.7 cd/A at high luminance of 3,000 cd/m2 and a low driving voltage of 5.9 V with Commission Internationale d'Eclairage (CIE) coordinates of (x = 0.30, y =0.39).

P‐175: A Study of Image Distortion and Brightness‐Uniformity Compensation in a Laser Projection System Using a 2‐D MEMS Scanner
Authors: Seo JungHoon , Kim Yongki , Choi JungHwan , Kwon Jaewook 
Published: October 2010

AbstractThis experiment created a laser projection system that used a 2‐D MEMS scanner as the driving method for the display device. The 2‐D MEMS scanner that can scan images horizontally and vertically was applied to drive using the bi‐directional scanning method. However, the laser beam velocity varies due to the mechanics of the scanning mirror, so it causes an image distortion and brightness uniformity issue. So, we suggest an image distortion and brightness compensation method based on the simulation of the mechanical scanner movement and optical system. We can also adjust each RGB color pixel alignment separately and reduce power consumption through the brightness uniformity compensation.

Authors: Tsai Chi‐Chu , Lin Fang‐Cheng , Huang Yi‐Pai , Shieh Han‐Ping D. 
Published: October 2010

AbstractThe power consumption of field‐sequential‐color (FSC) LCDs is much lower than conventional LCDs. To further reduce the power consumption of FSC‐LCDs, high power efficiency white‐LED was added to RGB‐LED as a RGBW 4‐in‐1 LEDs. The gray part of image was generated by using a white‐LED instead of mixing of red, green, and blue LED. The remaining color part in the image was generated by using RGB‐LED. Base on the efficiency of white‐LED, power consumption of FSC‐LCDs could be further reduced while still maintaining good image fidelity.

Published: October 2010

AbstractThe fast switching Multi‐electrode Driven Fresnel Liquid Crystal Lens (MeD‐Fresnel LC lens) for 2D/3D switchable autostereoscopic display was proposed. The MeD‐Fresnel LC lens not only performed fast switching rate (∼0.8s) without overdriving method, but also had the benefit of low operating voltage (∼3.2volts). Both of them were much better than conventional LC lens. Furthermore, it performed a well focusing ability which was similar to conventional LC lens.

Published: October 2010

AbstractIn‐Plane Switching (IPS) mode, one of the widely used LC modes in the LCD‐TV applications, has merits in the electro‐optic characteristics such as viewing angle and moving picture quality. However, it has also been pointed out to have low contrast ratio and not good enough in the black image quality. In this paper, we elucidate what the main factors of the low contrast ratio of IPS mode are and how to improve this black issue. Firstly, we have studied the range of black luminance perceivable by human eyes, and defined the required black luminance under the various ambient light conditions. In addition, we have developed the specific IPS technologies in order to meet the required black reference in all viewing angle directions.

Authors: Lee Chung‐Yung , Tseng Man‐Chun , Li Yuet‐Wing , Kwok Hoi‐Sing 
Published: October 2010

AbstractA new discontinuous alignment layer is developed. The formation of such discontinuous structure is created by self‐organized dewetting. Different dewetting mechanisms have been investigated. Such a discontinuous alignment layer can be fabricated on top of a continuous alignment layer. This heterogeneous surface for liquid crystal alignment can be used to produce arbitrary pretilt angles for the liquid crystal cell. Experiments using photo‐aligned polymer have been done to verify the dewetting theory. The alignment layers thus produced are proved to be robust. Moreover, the dewetting step is a fully controllable process and is compatible with existing manufacturing techniques.

AbstractA significant discrepancy has been found between the blurred edge time (BET) method to measure motion blur and moving image quality as perceived by the human visual system. MPPR, moving picture perceptual resolution, is proposed as a measurement method that more closely correlates to human perception of moving image quality. MPPR considers the contrast sensitivity function of human vision, resulting in an index that provides a more objective evaluation. The measurement system and algorithm are described.
52.1: Invited Paper: Highly Efficient White Top‐Emission PIN OLEDs for Display and Lighting
Authors: Birnstock Jan , Canzler Tobias W. , Hofmann Michael , Huang Qiang , Romainczyk Tilmann 
Published: October 2010

AbstractHere we report high efficiency white top‐emission (TE) OLEDs for display and lighting applications. Featuring sputtered ITO top contact, thin film encapsulation (TFE) and out‐coupling layers on top, high performance white TE OLEDs are demonstrated with power and external quantum efficiencies of 25 lm/W and 25%, respectively. Similar high efficiencies are also presented for top‐emission devices built on bendable metal substrates with a thickness of only 0.2 mm. Both types of devices have broad spectra with 1931 CIE color coordinates of 0.38/0.37 on glass and 0.43/0.40 on the metal substrate. The color rendering index (CRI) reaches a value of 80. In another white top‐emission OLEDs approach, semitransparent metal top contacts are combined with a scattering cap layer to achieve a high power efficiency of up to 20 lm/W. Those devices exhibit extremely stable color coordinates over a wide range of viewing angles, which is attributed to the scattering behavior of the cap layer material.
7.2: Wide Temperature Range Blue Phase Liquid Crystals for Display Applications
Authors: Xiang Jie , Lu Shin‐Ying , Chien Liang‐Chy 
Published: October 2010

AbstractWe report wide temperature range blue phase liquid crystals for display applications. Systematical analysis of the relationship of dielectric anisotropy value Δε and the blue phase liquid crystal BPLC temperature range shows that the BP temperature range increases as the Δε decrease. Additionally, we also find that as the chiral concentration of the blue phase increases, the BP temperature range decreases. The studied BPLCs also exhibit fast response time of 400 μs using IPS cells with a fixed cell gap and electrode line and space of 10 μm. These results can be explained based on the defect theory and would give effective guidance during the application of BPLC. Detailed physical, optical, dielectric and electrooptical study will be presented.
