41.3: Charge Carriers And Triplets In OLED Devices Studied by Electrically Detected Magnetic Resonance
Authors: Awlik Thomas D. , Ondakova Marina E. , Giesen David J. , Deaton Joseph C. , Kondakov Denis Y. 
Published: January 2009

AbstractOrganic Light‐Emitting Diodes (OLEDs) were investigated with an Electron Paramagnetic Resonance (EPR) technique that uses the effective device conductance as the detection channel. This technique enables us to identify and study charge carriers and triplet excitons with high sensitivity. Using a series of model devices, we demonstrate that this type of spectroscopy provides information about triplet energy transfer and the location of the recombination zone. The fundamental understanding about the extent of the recombination zone in various OLED architectures helps us to design devices with improved performance.
7.2: Carbon Nanotubes Synthesized at Low Temperature and a Novel Self‐Focusing Gated Field Emission Device
Authors: Hsu Yu‐Ying , Lin Kao‐Chao , Chen Hsia‐Wei , Juan Chuan‐Ping , Cheng Huang‐Chung 
Published: January 2009

AbstractA method for synthesis of CNTs at low temperature using thermal CVD is proposed. A multi‐layered catalyst, Co/Ti/Al, has been successfully utilized to synthesize carbon nanotubes at 500°C by thermal CVD via modifying the flow rate of reaction gases. The flow rates of ethylene, hydrogen, and nitrogen are determined to be 125, 10, and 1000 sccm to improve the growth and field emission characteristics of CNTs at low temperature. Moreover, a novel self‐focusing gated device was proposed to resolve the problem of electron beam divergence.

Authors: Rudin John , Kitson Stephen , Geisow Adrian 
Published: January 2009

AbstractPlastic displays require new manufacturing processes and techniques to achieve acceptable cost and performance. We present a novel additive, low temperature, atmospheric pressure, self‐aligned means of fabricating a plastic, bistable, full colour LC display. By using imprinting rather than photolithographic patterning, a scalable, low cost manufacturing route is possible.

Published: January 2009

AbstractSlot die coating is a cost‐effective, scalable process for applying continuous organic layers in OLED displays. Uniform submicron coatings can be obtained on patterned OLED backplanes from low viscosity fluids. Coating and drying defects can be reduced by adjusting fluid properties, e.g., surface tension, viscosity and concentration.
44.1: Invited Paper: Electrowetting‐Based Information Displays
Authors: Hayes Robert A. 
Published: January 2009

AbstractElectrowetting can be utilised to provide the pixel engine for an information display. By contracting a colored oil film electrically a high efficiency optical switch is obtained. In addition to the attractive optical properties, the principle exhibits a video‐rate response speed (<10 ms) and can be used to make high brightness color displays [1]. In recent times more attention has been focussed on manufacturing strategies related to launch of initial products. It is becoming increasingly clear that while the technology indeed offers disruptive front‐of‐screen performance the manufacturing of these displays can be non‐disruptive, leveraging up existing low‐end LCD infrastructure.

Authors: Valyukh Sergiy , Chigrinov Vladimir , Kwok Hoi Sing 
Published: January 2009

AbstractThe study of a tunable liquid crystal lens having a uniform cell gap, uniform applied voltage and non‐uniform anchoring energy was done. Optimal parameters of such a lens were found and discussed. We demonstrated that producing a desired director gradient profile with non‐uniform spatial distribution of the anchoring energy is a good alternative for other known methods applied for liquid crystal lenses.
44.5L: Late‐News Paper: All‐organic, Transparent Up‐conversion Displays with Tailored Excitation and Emission Wavelengths
Authors: Miteva Tzenka , Roberts Anthony , Nelles Gabriele , Yakutkin Vladimir , Baluschev Stanislav 
Published: January 2009

AbstractIn this paper we describe the World's first all‐organic, transparent, flexible, versatile color displays based upon triplet‐triplet annihilation assisted photon up‐conversion. The devices work with ultra‐low excitation intensities down to 10 mWcm−2 red/near‐IR light. The displays are based on metallated‐porphyrin sensitizers in combination with emitters in a transparent matrix and are driven by galvano‐scanned laser diodes. The displays have external quantum yield as high as 3.2%. The response time can be adjusted to specific application requirements — from a few μs to few 100 μs allowing kHz‐refreshment rate of the displayed information. It is possible to easily tune the optical density of the screens in order to obtain a desired transmittance for the excitation beam. We demonstrate the ability to achieve multicolor emission, using only one excitation source. There are practically no display size limitations and it is a very simple, cost‐effective fabrication.
45.1: Embedded All in Data Line Differential Signaling (EDDS) — A Novel Interface for Large‐Size TFT‐LCDs
Authors: Lin Che‐Li , Tsao Wen‐Yuan , Lin Wen‐Chi , Ho Shao‐Chung , Lin Jin‐Ho , Chan Cheng‐Hsun , Liu Yuen‐Hsiu , Lin Jr‐Ching , Huang Shi‐Yen 
Published: January 2009

AbstractIn this paper, we propose the novel interface EDDS (Embedded All in Data line Differential Signaling) to support high resolution and large‐Size TFT‐LCDs. EDDS uses 4‐level differential signaling, with a higher data rate per clock cycle and low EMI emission. Moreover, the control signals and clock of EDDS are embedded into four data lines, which not only decreases the number of wires between timing controllers (TCON) and source driver ICs (CDs), but also solves the issue of clock skew in conventional multi‐drop buses. By controlling the protocol, EDDS can flexibly support different specifications of TFT‐LCD and increase the quality of signal. In a word, the EDDS interface can effectively improve the performance of large‐Size TFT‐LCD applications and serve as a good solution for cost down.

Published: January 2009

AbstractIn this work, process variation on the field emission property of the fabricated field emission (FE) triode arrays with carbon nanotubes (CNTs) as the field emitters are explored. To fabricate the FE triode structure, nanoporous anodic aluminum oxide (AAO) thin layer was first prepared on the Si substrate, followed by the growth of vertically aligned carbon nanotubes in AAO pore channels by electron cyclotron resonance chemical vapor deposition. The SiO2 dielectric and Al gate electrode layers required for the triode structure were directly deposited on the CNTs. Reactive ion and wet etches were then used to open the FE area in the triode. We employ the finite difference time domain particle‐in‐cell method to calculate the structure FE property, where the results are calibrated with the collected FE current of the fabricated samples. The FE current of structure is then examined with respect to different shape, random height and angle of the CNT emitters. for symmetric shapes, like circle and square, the emission beam has been more focusing than triangle and trapezoid. The electric field of random height of CNTs is stronger than that of random angle. It is implied that the vertical CNTs has better FE property. Having the symmetric shape and vertical CNTs in triode structure benefits the FE sources for advanced flat display technologies.

46.2: Real‐Time Pen Tracking on Electronic Paper Displays
Authors: Feng Guotong , Barrus John , Gudan Ken F. , Chemishkian Sergey 
Published: January 2009

AbstractOn most electronic paper displays (EPDs), low update rates lead to a poor user experience especially for pen‐based markups. The slow update causes a remarkable delay between pen motion and visibility of the stroke. Even worse, this delay varies depending on the current part of the update cycle. This paper presents a real‐time pen tracking method for EPDs, using a new display driver on an unmodified E Ink hardware platform. This method compares favorably to the iLiad E‐Reader.

Published: January 2009

AbstractIn this paper, an asymmetrical dynamic model of the luminescent property of phosphors is first proposed and developed by measuring the experimental data. Then, based on the model, a novel drive strategy is derived to fully exploit the persistence effect of phosphors for a 20‐inch CNT‐BLU. It turns out that the resulting illuminative efficiency can be increased by more than 74% as compared with the most recent pulse mode driving strategy.

Authors: Park Hyun‐Sang , Ha Tae‐Jun , Han Min‐Koo , Woo Doo‐Hyung , Shin Kwang‐Sub , Kim Chi‐Woo 
Published: January 2009

AbstractWe design and fabricate a new digital ambient light sensor system on a glass substrate using a conventional low‐temperature polycrystalline silicon (LTPS) technology. The adaptive sensitivity control scheme considerably increases the input dynamic range from 30 dB to 60 dB. In the proposed system, analog‐to‐digital conversion (ADC) process is performed in the time domain instead of the voltage domain and is combined with light detection process. Because the complex analog circuitry is eliminated from the system, the proposed system can be readily integrated on the display panel.

49.3: Mechanism and Advanced Application of Rapid Laser Processing on SnO2 Thin Films for FPD Manufacture
Authors: Usui Reo , Mihara Yu , Morinaga Eiji , Iwata Yoshiharu , Satoh Ryohei 
Published: January 2009

AbstractA Nd:YAG laser processing on a SnO2‐system thin films for FPD manufacturing is investigated as an alternative to photolithographic etching on ITO. Because of the difficulty in realizing a low energy process on SnO2 due to a high melting point, we experimentally found the proper deposition condition and composition of SnO2‐system thin films. By considering two physical mechanisms, namely, plasmon oscillation and inverse bremsstrahlung process, we achieved satisfactory laser processing using only 2 J/cm2 of laser energy. This result leads to the possibility of high‐speed electrode patterning suitable for FPD mass production.

Published: January 2009

AbstractA new display technology based on droplet moving by electro‐wetting was introduced in 2007. Major improvements were made regarding hydrophobic layer, fluids, pixel layout, driving electronics and system design resulting in an operating voltage of less than 20 V for a 2 mm droplet. This enables new approaches for bistable and high reflective displays (e‐paper) with low power consumption, superior ambient light performance and wide temperature range. The pixel size can be varied between 0.5 and 10 mm for single pixels and being typical 2 mm for 8‐Segment as well as for (color) matrix displays driven by Passive Matrix.
