Authors: Lai Yueh‐Yi , Liao Wen‐Hung , Chang Kai‐Chieh 
Published: January 2009

AbstractThe issue of the color motion blur had become the most significant study of the LCD image quality. The motion blur edge width and the motion color bias are two major components of the color motion blur. In this paper, a color bias elimination technique was proposed to improve the image quality of motion color images. The added pseudo color was presented to reduce the level of color bias and new color bias index was used to judge the level of color bias of captured images via a pursuit camera system. The color lookup table (CLUT) had built automatically by this technique to improve the image quality of moving color images. Experiment results revealed that the added pseudo color images had the better image quality than the original moving images not only in the color bias index evaluation but also in the subjective test.

Authors: Chen Chih Wen , Lu Phoebe , Tien M. F. , Su Potato , Chang TingJui , Liau Wei Lung , Lien Alan 
Published: January 2009

AbstractIn this paper we succeeded to develop a approach by using new material, named gray bump in stead of current bump material to achieve excellent contrast ratio(CR) of liquid crystal display(LCD) at normal direction for MVA mode. Meanwhile, we needn't change any processes, and surely no additional cost. Except CR enhancement at normal direction, it can also reduce the oblique light leakage of dark state and improve the viewing angle. We evaluate the response time and reliability for image sticking of this new bump design and it has the similar response time and image sticking performance as the original bump design. Finally, we also show the CR >3000:1 32″ TV that adopting this new design and using higher CR polarizers with lower haze value surface treatment.

P‐49: A Gamut‐Mapping Algorithm with Separate Skin and Non‐Skin Color Preference Controls for Wide‐Color‐Gamut TV
Authors: Pan Hao , Daly Scott 
Published: January 2009

AbstractRecently emerging wide‐color‐gamut (WCG) TVs face two challenges. Viewers welcome the increase in color saturation of WCG TVs, but do not welcome unnatural skin color rendering due to the stretching of the narrower color gamut (such as the color gamut defined in sRGB/ITU‐R BT.709/601).In this paper, we propose a color gamut mapping algorithm (GMA□ to address the problem. The proposed GMA consists of two sub‐GMAs: the first sub‐GMA is focused on correctly rendering skin colors, and the second sub‐GMA is on rendering no‐ skin colors. In order to allow viewers to independently adjust skin and non‐skin colors according to their preference, the skin colors rendered by the first sub‐GMA and the non‐skin colors rendered by the second sub‐GMA go through two seperate viewer preference adjustment modules. Then the mapped and viewer‐adjusted skin and non‐skin colors are blended according to skin scores, which are scalars between 0 and 1. A skin score is assigned to a color to describe its likelihood to be a skin color and is obtained by extensive training on sample sets. Skin scores of an image are filtered by a linear lowpass filter to prevent generating artifacts.

Authors: Park Byung‐Hwee , Kim Seung‐Kyu , Jeon Chang‐Hoon , Hong Soon‐Kwang , Kim Byeong‐Koo , Ha Yong‐Min 
Published: January 2009

AbstractWe have developed a novel image quality enhancement method for AMOLEDs, which is based on advanced sunlight readability (ASR) technology. It consists of adaptive gamma peak control (AGPC) image processing algorithm and the reflectance reduction method (RRM). AGPC can boost the peak luminance of some specific images up to 2 times higher than that of normal driving in AMOLEDs while the maximum power consumption can be reduced by 40% depending on image contents. RRM can achieve half of reflectance from panel surface to cover of mobile device in applying optical plastic. The developed method is useful for acquiring more vivid image and better readability under sunlight condition.

AbstractThis paper presents a color sequential light‐emitting diode (LED) backlight power system for large‐scale LCD panels. The proposed power system uses ripple‐free circuit to improve image quality. In the proposed circuit structure, a set of power converter is operated in interleaving fashion and with switching regulation for generating two sets of output voltages to respectively supply red, green and blue LEDs by switch control. with this approach, an inductor for achieving ripple—free feature is adopted in each phase of the proposed interleaving converter. Compared to the conventional color—sequential LED backlight power system, the proposed power converter can be reduced its power converter counts, size, volume and cost, and increased its conversion efficiency significantly. Simulated results obtained from the proposed power system have been verified its feasibility.

Published: January 2009

AbstractOptimum slit design applied by the gray‐tone photolithography with protrusion and diagonal has been established by simulation and experiments. The adoption of protrusion and diagonal are able to defend loss of active layer and curve of Source/Drain. The stable and uniform gray‐tone process was accomplished by slit mask which had optimum diagonal slit design without ripple of transmittance in same TFT. Moreover we found that channel bias was changed by ripple in same transmittance.OPTOLITH simulation was able to assume gray‐tone pattern and seek optimum slit design but it was necessary to confirm by experiment. In this research, we have organized slit design guide applied by the gray‐tone photolithography through simulation and experiments.

P‐70: Improvement of Material Utilization of Organic Evaporation Source for Manufacturing Large‐Sized AMOLED Devices
Authors: Kim Hae Won , Han Seok Yoon , Shim Hyung Bo , Patrin John , Bresnahan Rich , Conroy Chad , Yoo Jay 
Published: January 2009

AbstractWe have developed a valved organic evaporation source for 4th generation substrate (730*920mm2) which enables shutoff during idling time and open process time only. So we could improve the efficiency of material utilization dramatically compared with conventional sources such as point sources or linear sources. Generally, linear source is longer than width of substrate and it makes material consumed so much. However, a valved source we developed is designed shorter than width of substrate to save material by preventing unnecessary flux out warding the substrate. In addition, it is comprised of 5 individual nozzles which have many holes in order to achieve the desired uniformity. As a result, we could obtain 30% of material utilization and 5% of non‐uniformity for a 730mm wide substrate. We expect this source can improve performance and reduce the COO (Cost of Operation).

AbstractReplacing the current non‐alkali glass with soda lime glass can significantly reduce the cost of the current TFT‐LCD module. One key step in manufacturing is to make TFT backplane on soda lime glass substrate. In this work, we demonstrate low temperature a‐ Si thin film transistor (TFT) at 200°C on soda lime glass. with the use of SiNx barrier to prevent sodium contamination, we show the TFT properties can be improved significantly and achieve TFT of saturation mobility 0.47cm2/Vs, threshold voltage 0V, off current 77×10−11 A, sub‐threshold swing 1.0 V/dec. We also show that our TFT device has comparable or better threshold voltage stability as compared to those made in non‐alkali glass. Finally, we show the robustness of SiNx barrier against long term sodium migration.
