Authors: Jin Dong‐Un , Chowdhuri Abhijit Roy , Takoudis Christos G. , Zhang Jie , Gamota Daniel 
Published: January 2005

AbstractA simple, low‐cost patterning technique suitable for high volume manufacturing of thin film transistors is proposed. This method utilizes photolithographic templates and electroless plating to generate high‐resolution metal patterns on flexible substrates. A major advantage of the process comes from simultaneous copper deposition and template dissolution that reduces the effective number of processing steps.

Published: January 2005

AbstractWe have developed the new process about PI Poly Imide: Liquid crystal alignment layer of TFT LCD rework with photo‐spacer and/or protrusion and/or resin black matrix for mass production using new chemical & EPD technology.In case of previous PI rework using O2 / SF6, it is seldom possible to remove selectively PI layer without a little damage to photo‐spacer and/or protrusion and/or resin BM including device characteristics such as I‐V curve of TFT and CIE color coordinates.But the present O2 / N2 chemical let the PI layer rework be embodied with a little damage to the photo‐spacer and/or protrusion and/or resin Black Matrix replaced for previous Cr metal BM. Therefore, it is possible for TFT LCD makers to cut‐down drastically the failure‐cost in case of using photo‐spacer narrow & constant cell gap and/or protrusion Vertical Alignment mode‐multi vertical alignment for wide viewing angle and/or resin BM for the 5th generation mother glass size TFT‐LCD.

Published: January 2005

AbstractWe propose a real‐time 2D to 3D image conversion method that can generate stereoscopic image with different perspective depth using motion parallax from a 2‐D image and offer realistic 3‐D effect regardless of the direction and velocity of the moving object in the 2‐D image. The stereoscopic image is generated by computing the motion parallax between adjacent two 2‐D images using the proposed method for motion detection and region segmentation. The proposed method is suitable for real‐time 2‐D to 3‐D processing on various image formats. It has been evaluated the proposed method by seeing the stereoscopic image on monitor.
P‐52: Large Fiber‐Based Displays
Authors: Moore Chad 
Published: January 2005

AbstractA novel method of creating the structure in a panel using complex‐shaped fibers and tubes with co‐drawn wire electrodes will be discussed. The fiber‐based method of manufacturing eliminates all multi‐level processing, all photolithography, and all vacuum deposition steps. In addition, it reduces the number of process steps by a factor of two, simplifies the manufacturing equipment, and removes the requirement for large area process equipment. These advantages lead to a one‐tenth reduction in upfront capital cost and over a 50% lower manufacturing cost.

P‐59: Improved Waveform for the Sustain Pulse for High Luminance
Authors: Lim Jong‐Sik , Kim Hyun‐Seok , Kim Joon‐Yub 
Published: January 2005

AbstractA new waveform for the sustaining pulse for the AC PDP that improves the luminance and the luminous efficiency is presented. When the conventional sustaining pulse is used, the discharge that produces the VUV Vacuum Ultra Violet tends to be concentrated to the narrow region between the two sustain electrodes. In order to expand the VUV generating region to a wider range, efficient ITO Indium Tin Oxide shapes have been investigated. This approach often required costing complicated structure for the electrodes and showed limitation in improving the luminance. By simply changing the waveform for the sustaining pulse without changing the structure of the electrodes, more efficient discharge can be produced resulting in higher luminance and higher luminous efficiency. The experiments using the new waveform for the sustaining pulse showed luminance of 868 cd/m2 and luminance efficiency of 1.18lm/W at the sustaining frequency of 71kHz. It is 30% and 181% improvement compared to the luminance of 667cd/m2 and to the luminous efficiency of 0.42 lm/W measured using the conventional sustaining pulse respectively.
P‐61: New Driving Method for High Speed Addressing in AC PDP
Authors: Kim Jae‐Sung , Yang Jin‐Ho , Whang Ki‐Woong 
Published: January 2005

AbstractA new high speed addressing method is proposed to reduce the addressing time below 1us per line in AC PDP. In this method, priming discharges are used to achieve a high speed addressing without adding an auxiliary electrode. The scan and sustain electrodes are divided into two groups even and odd lines and every even line is scanned first with priming discharges in the adjacent odd line electrodes and then every odd line is scanned through the selective erase addressing method. In the panel experiment, the address discharge time lag was reduced to one half of that of the conventional method when the new addressing method was used. Therefore, this addressing method is adequate to drive a high resolution PDP with a single scan method and it also can be used for high luminance and high picture quality by allocating the increased display time to sustain period or extra subfields.

Authors: Kim Joon‐Yub , Lim Jong‐Sik , Kim Hyun‐Seok 
Published: January 2005

AbstractThe variation of the wall voltage and the wall charge during the sustain period were investigated using an equivalent circuit model for AC PDPs. Efforts of many researchers have been invested to understand the behavior of the wall charge. This paper presents an equivalent circuit model for AC PDPs consisting of capacitors and thyristors. The equivalent circuit model is based on the physical structure of the AC PDP and the I‐V characteristic of the discharge spaces. This equivalent circuit model can be easily implemented in the standard simulators such as SPICE and can easily simulate the variation of the current, charge and voltage involved in AC PDPs as the supply voltage varies. The simulated results using the equivalent circuit model in SPICE are presented and compared with the measured results.

P‐73: ITO Characteristics on Different Under‐Layer for AM‐OLED Displays
Authors: Hsieh Hsiu‐Chun , Chang Shih‐Chang , Tsai Yaw‐Ming 
Published: January 2005

AbstractThe characteristics of ITO film on different under‐layers including Si‐containing insulators and organic materials were investigated. It was found that the visible light transmittance of ITO film on different under‐layer is maintained, however, the surface morphology of ITO film depends strongly on different underlayers. The surface roughness of ITO film on the organic materials is 3 times larger than that on insulating materials. Also observed is the strong dependent of surface roughness on luminance efficiency. Base on these results, a new pixel structure is proposed for AM‐OLED applications. With this new pixel structure, the good properties of ITO film can be obtained and used for high efficiency and long lifetime AM‐OLED displays.

P‐81: Enhanced Efficiency of Red Organic Light‐Emitting Diodes by Using Partially Doping Method
Authors: Han Jeong Whan , Kim Byung Soo 
Published: January 2005

AbstractRed organic light‐emitting diodes (OLEDs) with dotted‐line doping layer (DLDL) structures or totally doping layer (TDL) structure are fabricated by ultra‐low pressure molecular beam deposition method. The structure of the OLEDs with DLDL structures studied is ITO/α‐NPD(40nm)/(Alq: DCJTB(3%))n (30nm)/ Alq(30nm)/MgAg(150nm). Here, n is the DLDL number varying from 2 to 8. The red OLED with DLDL of 6 exhibits current efficiency up to 3.94Cd/A at 100Cd/m2, which is 46% increase compared to that of the red OLED with TDL structure. We attribute this enhancement to the fact that the charge carriers and the excitons are effectively trapped in the DLDLs and generate photons, and also distributed over the DLDL region, hence this decreases the quenching of emission exciton.

Published: January 2005

AbstractIn this study, the inorganic thin‐film passivation layer was newly adopted to protect the organic light emitting diodes (OLED) from atmospheric moisture and oxygen. Using the electron beam evaporation system, both the various kinds of Na2O and SiO2 based inorganic composite films were deposited onto the poly(ethersulfone) substrate, and their water vapor transmission rates (WVTR) were investigated. The WVTRs as a function of layer thickness were studied and the dependence of the WVTRs as a function of composition rate in composite was also investigated. In this investigation, we can found that the WVTR of SiO2 based composite layer showed the lowest value compared to other inorganic composite layers. Based on this result, we can estimate that the time‐dependent light‐emission properties of OLED will be dramatically enhanced by adopting an inorganic composite layer.
P‐94: Polymer Cholesteric Liquid Crystal Flakes for Particle Displays
Authors: Kosc Tanya Z. , Marshall Ken L. , Jacobs Stephen D. 
Published: January 2005

AbstractPolymer cholesteric liquid crystal (PCLC) flakes suspended in a moderately conductive host fluid reorient in the presence of an AC electric field within a specific frequency range, causing a dramatic change in flake reflectivity. PCLC flakes reflect light of a specific color and (circular) polarization, thereby eliminating the need for backlighting, color filters, and polarizers to attain unique optical effects. Reorientation can be seen in fields as low as several milli‐volts per micron, and reorientation times are on the order of several hundred milliseconds, thereby approaching response times for both nematic liquid crystal displays and other particle displays. Applications for electro‐optic devices, decorative commercial and consumer products, and displays, particularly electronic paper, are envisioned.

Published: January 2005

AbstractPolyimide surfaces bombarded by a low energy argon ion beam align liquid crystals parallel to ion beam exposure direction. By ion beam conditions, such as the energy of the incident ions, the angle of incidence and exposure time, the unidirectional out‐of‐plane liquid crystal (LC) tilt angle is changed. These are related with the remaining π‐bond of polyimide which is not destroyed by ion beam bombardment. For application in LCDs, unit cells fabricated by ion beam alignment method are compared with one which manufactured by the rubbing method. And The TN cell fabricated by ion beam alignment method has enough retention time to apply to TFT(Thin Film Transitor) LCDs

Authors: Engel‐Dvir Shlomit , Ben‐Shalom Amir , Coates David 
Published: January 2005

AbstractA method of correcting for the human eyes poor perception of red colors in cholesteric liquid crystal (ChLC) mixture is presented. The reflection of a band for ‘red’ ChLC mixtures is tuned around 600nm but it usually appears orange or even brown due to the eye seeing the shorter wavelength overtone bands more effectively. A technique to improve the perceived red color without lowering the stability of the liquid crystal mixture is presented. The method improves not only the red color but the entire RGB color triangle.

AbstractA novel transmission‐type display based on spectrally pure waveguiding pixels is proposed. In this display, a particular wavelength of light is selected by a slanted holographic‐polymer dispersed liquid crystal (H‐PDLC) pixel, waveguided, and redirected to the viewer. We present the electro‐optic performance of slanted H‐PDLCs for this proposed application. These novel holographic pixels can be electrically switched by voltages as low as 60 V, which is a much lower voltage than the reported switching voltages for H‐PDLCs when used in the conventional reflective mode.
