8.3: New Bipolar Ramp Waveform for Enhancing Low‐Gray‐Level Expression in ACPDPs
Authors: Park Ki‐Hyung , Cho Ki‐Duck , Tae Heung‐Sik , Chien Sung‐Il 
Published: January 2005

AbstractA new bipolar ramp waveform that can reduce the minimum luminance level considerably is proposed to improve the low gray level expression in AC‐PDP. In the new bipolar ramp waveform, the conventional first subfield with a sustain‐period is replaced by the new first subfield that consists of the first negative square pulse and second positive ramp pulse during a scan‐period. The weak discharge produced by the second positive ramp pulse is used to generate and control the low luminance level stably.

33.4: An Improvement Process for Gate Oxide of LTPS TFT by Using N2O Plasma Nitridation
Authors: Chou Lin‐En , Ting Hung‐Che 
Published: January 2005

AbstractIn this work, the nitridation effects for the gate oxide of low temperature polycrystalline silicon (LTPS) thin film transistors (TFTs) by using N2O plasma were presented. According to the experiments and discussions in this paper, it was believed that the incorporation of nitrogen atoms into SiO2/Si interface was responsible for the improved quality of the oxide. Therefore we used N2O plasma instead of thermal and NH3 nitridation to get better performance of LTPS TFTs. Furthermore, the N2O plasma nitridation process also had advantages of the higher throughput and yield in LTPS TFTs fabrication.

40.4: New Photoalignment Polymeric Materials with Excellent Photosensitivity and Stability
Authors: Li X. , Zhong Z. , Lee S. H. , Lee M.‐H. 
Published: January 2005

AbstractNovel soluble photoalignment materials with high photosensitivity and good thermal stability were synthesized by chloromethylation of 6FDA‐ODA polyimide, and their photoalignment properties were investigated. The photosensitivity of 6FDA‐ODA polyimide was improved greatly by the introduction of chloromethyl side group. The ECB LC cell made with photoaligned films could be stored at 85°C. for at least 14 days without deteriorating LC alignment. The irradiation of polarized UV light on the polymer surface induced thermally stable alignment of LC due to the surface anisotropy caused by photodecomposition of polyimide main chain.

43.1: Image Enhancement for Reflective Displays
Authors: Nenonen Petri , Yrjänäinen Jukka 
Published: January 2005

AbstractThe reflective and transflective LCD technologies offer attractive solutions for color displays that are used in handheld devices. These technologies make possible to obtain a full color display with low power consumption by using ambient illumination as light source. When there is not enough ambient light an internal light source can be used. The current generation of displays has quite adequate quality for viewing color images in some conditions, but they still have also some insufficient properties. The color gamuts and contrast ratio of the displays are small and dependent on the illumination. We have researched how the properties of the displays affect imaging applications and how those can be overcome by using image processing means. We are focusing on image enhancement algorithms, which we have tested under different viewing conditions. Especially algorithms that are effectively implementable are interesting. In this case the target is to increase the visibility and the subjective quality of the image on the display as opposed to reproduce the originally intended appearance exactly. The achieved results show that the perceived image quality and the usability of the display can be enhanced significantly using image enhancement techniques.

AbstractInstability has long been a barrier to the use of a‐Si AMOLED backplanes. We present here the first demonstration of proven stability of a‐Si AMOLED pixels. Over 7000h of stability data is shown for pixel circuits that compensate for threshold‐voltage shift, temperature, and OLED degradation (extreme compensation). This demonstrates that stable AMOLED backplanes are achievable using well‐established and proven a‐Si TFT technology in mainstream use by the flat panel display industry.

Published: January 2005

AbstractHigh performance new blue‐emitting host‐dopant systems, which consist of pyrene‐substituted fluorene hosts such as DPYFL01 and diarylamino‐substituted origo(fluorenylene)s represented by BDT3FL as dopants, have been developed. The new host material,DPYFL01 showed high electron‐mobility with 1×10−3 cm2/Vs. A device using DPYFL01 demonstrated blue emission (CIE: x, y = 0.15–0.16, 0.20–0.21) with high power efficiency of 4.5 lm/W at 200 cd/m2. The use of 20%BDT3FL inDPYFL01 resulted in deep‐blue emission (CIE: 0.15, 0.15) while keeping high power efficiency of 4.6 lm/W at 3.1 V. The device‐structure optimization together with the use of an additional host,C‐H01 afforded deep‐blue emission (CIE: 0.15, 0.14) and higher power efficiency of 4.9 lm/W and external quantum efficiency of 3.9 % at 4.3 mA/cm2 with 200 cd/m2. Lifetime of the optimized device using 10 %BDT3FL was estimated to be over 10,000 hour at an initial luminance of 200 cd/m2.

Published: January 2005

AbstractA fast‐switching and scattering‐free phase modulator using polymer network liquid crystal (PNLC) is demonstrated at λ =1.55 μm for laser beam steering application. The strong polymer network anchoring greatly reduces the visco‐elastic coefficient of the LC. As a result, the PNLC response time is improved by ∼300X, although the threshold voltage is increased by ∼25X. Computer simulation results agree with experiments well.

This change can be characterized as visual tunneling.
61.3: Invited Paper: A Virtual Display for Mobile Use
Authors: Häkkinen Jukka 
Published: January 2005

AbstractMobile devices have small displays, so a virtual display that would bring the benefits of a large computer display to users would be an interesting mobile accessory. However, sickness symptoms are a problem that should be solved before a virtual display can be successful. To explore the symptom levels induced by virtual displays, we have tested several head‐worn virtual display types in various contexts. Our results indicate that monocular and stereoscopic displays induce significant amount of adverse symptoms. On the other hand, the symptom levels induced by biocular displays are not different from the symptoms induced by direct view displays. The results suggest that a biocular display might be the best alternative as a mobile accessory.

AbstractSingle carrier devices have been made with LUMATION Light‐Emitting Polymers (LEPs) in order to gain an understanding of the majority charge carrier in the system. By changing the cathode structure, the majority carrier and charge balance in the system can be tuned. As a consequence, the lifetime of the device can be tuned and yields characteristic luminance decay. Using this information, and data from single carrier device lifetimes an understanding of mechanisms of diode device degradation can be gained.
