38.4: Low Voltage Cathodoluminescent Properties of Y2O3‐based Nano‐Particle Phosphors
Authors: Nagata Tomohiro , Nakayama Takahiro , Murakami Hirohiko 
Published: August 2007

AbstractThe practical cathodoluminescent properties of Y2O3‐based nano‐particle phosphors were measured using 3kV accelerating voltage. These phosphors showed the luminance, chromaticity and lifetime superior to the phosphors for CRT. Furthermore, in order to evaluate the application of field emission backlight units (FE‐BLU), we synthesized the white phosphor by mixing red, green and blue nano‐particle phosphors. By the adjustment of the amount of mixtures, fine white color and high luminescence were also observed.
39.1: Adaptive Dimming and Boosting Backlight for LCD‐TV Systems
Authors: de Greef Pierre , Hulze Hendriek Groot 
Published: August 2007

AbstractThe limited transmittance of LCD panels can be observed as a waste of energy, leading to a limited brightness. Light leaking through LCD panels driven to black, can be observed as a poor black‐level, limiting the contrast ratio.Adaptive Dimming Backlight technology can be applied to attenuate the backlight luminance, improving local contrast, black‐level and saving power.The optical crosstalk between the controllable backlight segments has a negative impact on the dimming performance, limiting the spatial backlight luminance modulation. Crosstalk Compensation can partly compensate this artifact, enhancing the spatial modulation of the segments.Adaptive Boosting Backlight technology can be applied to boost the output of the panel over 100%. This improves the local brightness and contrast for a sparkling picture, still saving power.Crosstalk compensation enables deeper dimming. Deeper dimming improves on contrast and enables more boosting for an even brighter picture. So when these technologies are combined:
The contrast may increase up to 5 times (CCFL/EEFL).
The brightness may double and contrast may increase up to 20 times (HCFL).
Alternatively, for 2D‐Dimming the spatial contrast may increase up to a factor of 100 and the temporal contrast may increase to infinite (LED). At the same time, up to 50% average power can be saved!

Published: August 2007

AbstractA 32 inch high contrast LCD TV using LED backlight is demonstrated. The LCD TV dynamically manipulates the brightnessr of individual LEDs to largely enhance the display contrast and reduce the power consumption. Preliminary results indicate the contrast can be up to 125,000:1, with maximum luminance of 500 cd/m2. Compared with the static LED backlight, up to 70% of the power can be saved depending on the average picture level (APL) of the image.

Authors: Chen Hanfeng , Sung Junho , Ha Taehyeun , Park Yungjun 
Published: August 2007

AbstractThis paper presents a pixel compensated backlight dimming method for improving contrast on LED‐LCD. The backlight luminance is dimmed locally along with image contents, and pixel values are compensated synchronously according to the luminance profile of dimmed backlight. Static contrast above 20000:1 has been achieved on a large size LCD with the proposed method and no obvious artifacts are observed.

Authors: Jones J. Cliff 
Published: August 2007

AbstractThe first commercial use of the Zenithal Bistable Display (ZBD®) is for electronic point of purchase (epop™) signage in the retail sector. As a reflective bistable display, this novel LCD technology only consumes power if the image is updated. It is addressed using a simple passive matrix and consequently allows large amounts of information to be displayed using low cost STN drivers.

Authors: Hong Soon‐Kwang , Kim Byeong‐Koo , Ha Yong‐Min 
Published: August 2007

AbstractWe have evaluated various compensation techniques to improve the brightness uniformity of AMOLEDs fabricated by excimer laser crystallization. Every method has some limitations in terms of performance and cost in case that compensation functions are implemented in pixel arrays. Recently, we have developed a new compensation technique of which function is implemented in the driving IC chip instead of pixel arrays. In addition, we have also developed a novel solid phase crystallization (a‐SPC) process so that both the uniformity of display and the fabrication cost performance can be enhanced. A 20.1‐in. sized AMOLED has been successfully demonstrated by this novel crystallization technology.

Published: August 2007

AbstractThe combination of white OLED and color filter (CF) is the most mature solution for making large‐area AMOLEDs. The system can benefit from introducing a white subpixel. We compared the power efficiencies of RGB and RGBW system. As a basis for the comparison, we also propose a reference video called FC in which every color point in the cubic RGB space has the equal probability of appearance. We found that the RGBW system has 16.7% lower power consumption and 23% lower current stress (thus longer lifetime) for the reference video. We also analyzed various kinds of videos from DVD movies, HDTVs and IT graphics to find that in these actual video materials, there is much more utilization of white so that the power consumption is roughly a half of that for the FC video. The reduction is so significant that the W OLED + RGBW CF system has 60% lower power consumption than the RGB CF system and only 50% higher power consumption than the RGB OLED (no CF).

Published: August 2007

AbstractEfficient field emission from nanostructural ZnO can be engineered by morphological and electronic design. By fabricating ZnO into pin structure with sharp tip, low threshold and high emission current density were obtained. By doping ZnO, the Fermi level was lifted up to increase the conductivity and reduce the emission barrier. We explored both dry and wet method for ZnO field emitter fabrication. ZnO field emitters are oxidation resistant, which allows a less stringent processing process (annealing in oxygen ambient) and low vacuum operation.

Published: August 2007

AbstractWe have developed novel growth technique for carbon nanotubes (CNTs) by using resist assisted patterned growth. The CNTs can be grown directly on the patterned catalyst surface without diffusion barrier. The growth site patterns were fabricated on Ni/Si substrate by a conventional lithography method using photo‐patternable resist. The CNTs are uniformly grown on various islands, which defined by selective positioning technology. Various numbers of island‐emitters were grown and measure the electron emission properties by using diode structure. The total electron emission characteristic shows very linear with number of island emitters. Emission current of the one‐emitter island is 7.8 nA at 9 V/μm with 40 μm pitch, 10 μm island diameter.

AbstractA novel 3‐fold dynode structure was introduced into the CNT‐FED for improving its uniformity and electron amplification. The 0.5″ and 5.6″ dynode of metal plates was etched with numerous holes of various cross‐sections and coated oxides to supply high efficient passage for electrons. Experiments have been carried out to study the effects of oxides and oxide film thickness on the electron multiplication of dynodes. We observed that several metal plates not only shield the cathode from the high electric field of anode, but also distribute uniform electrons inside each pixel cavity. At present the 3‐fold dynode exhibits electron multiplication factors larger than, but close to, unity.

Published: August 2007

AbstractThe base vacuum level before filling a discharge gas is an important parameter to affect both the address and sustain discharge characteristics in an AC‐PDP. for the improvement in discharge characteristics, the vacuum sealing method is adapted. In this paper, the vacuum sealing method to enhance a base vacuum level is adopted to minimize the residual impurity gas, and the resultant changes in the address and sustain discharge characteristics, such as a dynamic voltage margin, firing voltage, statistical address delay time, and secondary electron coefficient, were examined in comparison with the conventional sealing method in the 42‐in. AC‐PDP with a high Xe (11 %) content. The high base vacuum level in the 42‐in. panel fabricated by the vacuum sealing method can enhance the discharge characteristics, such as a dynamic voltage margin, a firing voltage, and a statistical address delay time, which are caused by a decrease in the residual impurity gases and an increase in the secondary electron coefficient. In particular, in the vacuum sealing method, the sustain voltage was decreased by about 30 V, and the address voltage was also decreased by about 7V in the Xe (11 %) condition.

Published: August 2007

AbstractThere has been a rapid increase in the number and variety of video sources that are now available to the consumer. In addition to the traditional broadcast and packaged media sources, consumers now get video from internet sources like YouTube, Google, iTunes, etc., as well as “place‐shifted” video from sources like the SlingBox, etc. These new video sources are often low‐resolution and full of artifacts. However, consumers expect to be able to view all of these types of video on their large‐screen flat‐panel TVs and obtain a consistent high image quality. Achieving this requires a new class of highly adaptive digital video format converters. This paper describes the first member of a new family of ICs that has been designed to meet this need.
44.2:Distinguished Paper: Adaptive Contrast Enhancement for Digital Video
Authors: Srinivasan Sujith , Balram Nikhil 
Published: August 2007

AbstractThis paper describes a new real‐time adaptive contrast enhancement technique for digital video applications. The method is a modified contrast limited histogram equalization based procedure that adapts according to the input video statistics. The method decides whether to increase dynamic range or to light up dark regions of the image. As a result, for dark images, details in dark areas are enhanced without affecting mid and bright pixels. However for images with average brightness, the dynamic range of the scene is increased. It is adaptive and provides a localized contrast enhancement effect which is not possible with traditional contrast stretching/gamma LUT based approaches. Unlike traditional histogram equalization based approaches, the technique described automatically tones down its effects on pictures that are prone to contouring and other artifacts and is able to correctly enhance letter‐boxed as well as full‐screen video.

Published: August 2007

AbstractA three‐component white OLED device using fluorescent materials was developed for full‐color displays. Very high power‐efficiency of 17 lm/W@10mA/cm2 and long lifetime over 30,000hr@1,000cd/m2 were achieved by using new carrier transport materials with high mobility. Power consumption and half lifetime of a 2.2″ QVGA full‐color display were estimated by simulation to be about 200mW(200cd/m2,100%ON) by combining the device with top‐emission structure. This value is comparable to the state of the art of LCDs.
48.1: Behavior of LCD Panel During Bending
Authors: Gulati Suresh T. , Helfinstine John D. , Ono Toshihiko , Lapp Josef C. 
Published: August 2007

AbstractWhen an LCD panel is subjected to pure bending, for example during strength measurement or proof testing, the question arises “does it behave as a monolith of twice the substrate thickness? or does it behave as two independent substrates?”. Both theory and experiment suggest that the panel behavior depends on how its edges are held together, i.e. well bonded? or loosely held together? Indeed, the former renders the panel nearly twice as strong and four fold as stiff as the latter. This paper will provide the analysis of the bending behavior of a two‐layer laminate using St Venant flexure theory. Experimental data, using strain gages, will demonstrate that an LCD panel can behave either as a monolith of twice the substrate thickness or two independent substrates depending on how its four edges are held together in the support structure including the bezel. The paper derives appropriate equations for computing panel strength when it is bent to constant curvature or when its specimens are flexed in 4‐point bending for both i) well bonded edges and ii) loosely held edges.

Published: August 2007

AbstractA plasma‐beam‐irradiated PI film has been used in flexible liquid crystal display manufacturing. The beam had energy of 450 eV and incident angle of 70° with respect to normal flexible indium‐zinc‐oxide coated substrate. The pretilt angle and anchoring energy of LCs on plasma aligned PI surface were almost identical to those on rubbing aligned PI surface. However, the optical performance of plasma aligned cell was superior to the rubbing cell under various bending conditions. Furthermore, such non‐contact alignment technology is suitable for large area and roll‐to‐roll fabrication of flexible LC films.

AbstractIn this paper, there is a description of the development of PDP televisions equipped with ultra‐fine sub‐pixels in order to become competitive in the large‐scale TV market. Delta and triode cell geometry was implemented to establish the high luminescence in the 50‐inch FHD PDP models. In order to lower circuit costs, a modified scan pulse was used to establish a 1080p single scan. Furthermore, the possibility of developing a QFHD (2160/p) PDP television will be briefly mentioned. We have concluded that a new design is necessary in order to generate a product with ultra‐fine sub pixels that will not increase the breakdown voltage even if the sub‐pixel dimension is decreased to 100um.
