3.5: Novel Broadband Retarder Evaluation Metrics for 3D Projection Display
Authors: Chang Yu‐hsun , Huang Kuo‐Chung , Lin Hoang‐Yan , Tsai Chao‐Hsu 
Published: October 2010

AbstractBroadband retarder BBR, keeping away from crosstalk between the binocular parallax images, is the key component of the polarization based 3D stereoscopic display system. In case of rotating the viewer's polarization glasses, circular polarization light is needed for preserving stereo perception. Eliminating wavelength depended optical properties is the goal for BBR design. BBR has been widely applied for LCD display. However, the previous studies did not meet the rotating analyzer and in those cases did not have compensated retarder. Since the analyzer rotates, retardationwavelength relationship is failed to represent both the transmittancewavelength property and the color performance. In this paper, we use a numerical solution rather than an analytical solution to analyze dispersive issues. The transmittance, crosstalk and color shift metrics are used to evaluate the BBR quality, and 25% crosstalk, 33.73% red color shift and 26.4% green color shift problems are improved in our design.

Authors: Chen Kuan‐Yu , Chang Yung‐Ting , Ho Yu‐Hsuan , Lin Hoang‐Yan , Lee Jiun‐Haw , Wei Mao‐Kuo 
Published: October 2010

AbstractTaking organic emitter apodization calculated from electromagnetic theory as input, the angular luminance enhancement of a microlens‐array‐film (MAF) attached OLED (organic light‐emitting device) can be further evaluated by raytracing approach. First, we assumed artificial emitters and revealed that not every OLED with MAF has luminance enhancement. Then, the OLEDs of different Alq3 thickness were fabricated and their angular luminance measurement validated simulation results. Mode analyses for different layers were performed to estimate the enhancement potential of the MAF attached devices. In conclusion, the organic emitters with higher off‐axis‐angle luminous intensity cause lower out‐coupling efficiency but gain higher enhancement after the MAF attached.

14.3: Reserved Highlight Region for HDR and Megacontrast Display Algorithms
Authors: Daly Scott , Meylan Laurence , Kerofsky Louis 
Published: October 2010

AbstractWe discuss an algorithm that works with the concept of a reserved highlight region. It primarily addresses the problem of displaying legacy images calibrated for StandardDynamic Range displays onto displays having higher dynamic range, such as Megacontrast displays having standard brightness and bitdepth, as well as HighDynamic Range displays having increased brightness and bitdepth. The technique reserves headroom of the display range past maximum diffuse white for specular highlights and selfluminous objects. The paper discusses how to detect the specular highlights and light sources, how to construct a tonescale with reserved headroom, and different experiments conducted to learn how much of the dynamic range should be allocated for this upper luminance.

Authors: Langendijk Erno H. A. , Hammer Martin 
Published: October 2010

AbstractStatic contrast in LCDs can be improved by using local dimming backlight techniques, but it is still orders of magnitude lower than that of OLED. However, glare in the human eye limits the visible contrast and suggests that a very high contrast is not required. In this paper we estimate how much contrast is actually required in a display and compare that with today's OLEDs and local dimming LCDs.

Published: October 2010

AbstractA novel fivemask low temperature polycrystalline silicon LTPS complementary metal oxide semiconductor CMOS structure was verified by manufacturing the thin film transistor TFT test samples using the proposed fivemask LTPS CMOS process. In integrating the fivemask CMOS structure, a selective storage area formation process was developed, without additional photo mask steps, to solve the sputtering damage encountered inevitably in the contact between polycrystalline silicon pSi and storage metal. In addition, the selectively thin dielectric layer increased capacitance per unit area, and thus, increased the aperture ratio of AMLCD panel by reducing the capacitor area without reducing GI thickness in TFT
