Authors: Kim HyunSeung , Kang Yoojin , Bang Sungjin , Hwang Jungsub , Kim YuHoon , Kwon Jangun , Yoo JinJang , Lim Moojong 
Published: July 2013

AbstractBlue primary's materials of three‐primary color display have been hot issues in display industry because the blue materials of LED or OLED generally have shorter lifetime than red and green materials. Thus the choices of blue materials are very limited when applying them to displays. This paper, to overcome the limitation on selecting blue color materials, we suggest visually acceptable color ranges of blue primary when compared to the blue color of Rec. 709.

Published: July 2013

Abstractthe charge recycling match (CRM) technique is proposed to reduce dynamic power dissipation in display column drivers. The CRM technique can save much power in some polarity operation, which is hard to have charge recycling in conventional techniques. Theoretical analysis and experimental result show maximum dynamic power reduction of 12% and 30% in column inversion panel with R/G/B stripe pixel arrangement and Zigzag panel, respectively. The proposed method is suitable for voltage mode driving scheme and capacitive loading display column driver special in thin‐film‐transistor (TFT) liquid crystal displays (LCDs) and active mode organic light‐emission‐diode (AMOLED) display. A complete method application including circuit structure, algorithm and hardware implement are demonstrated in TFT‐LCD application.

Published: July 2013

AbstractFour‐point‐bending (4PB) test is a common method to evaluate the strength of a panel. In this paper, we discussed the behavior of organic light emitted display (OLED) during bending. We found most of OLED panels show a unique fracture mode that fracture originates from the sealing material frit, which is different from the glue used in LCD panels. This study verified this phenomenon through experiment and simulation.

Authors: Liang John Z. , Schweiger Robert S. , Proulx Tina M. , Greene Raymond G. 
Published: July 2013

AbstractThe direct mechanical touching usually generates mura on a LCD panel. The touch mura cannot always be flashed in a very short period. Touch mura exists in almost every mode of LCD. In this paper, a new type of mura which generated during the LCD module assembly process is investigated. The research results show that LC orientation change from original alignment direction is the main driving‐force of light leakage. A solution to prevent this type of mura is proposed for industrial manufacturing process.

P.147L: Late News Poster: Adaptive Anisotropic Diffusion for Depth Map Enhancement in 3D Video Coding
Authors: Lim Ilsoon , Wey Ho‐cheon 
Published: July 2013

AbstractWe present a novel depth map enhancement scheme in depth map coding. For this purpose, we develop anisotropic diffusion that enhances the coded depth map by the noise removal. Unlike the traditional anisotropic diffusion, our approach is different in that the distortion optimization scheme is performed in the encoder and then the optimal diffusion parameters are transmitted to the decoder. More specifically, the diffusion function and the number of iteration number, which have a big influence on the noise removal, are studied. The iteration number, which minimizes the distortion of depth map, is determined and transmitted to the decoder frame by frame. The decoded depth map is enhanced using the anisotropic diffusion, which is performed with the optimal parameter. Finally, the depth enhancement that performs the anisotropic diffusion is implemented in the latest 3D video codec. This results in 0.058dB(depth map) BD‐PSNR improvement and 0.009dB(rendered view) BD‐PSNR improvement on average when compared with 3DV HEVC‐based test model and offers the superior subjective quality in the rendered view.

AbstractBuffer layers on flexible substrates have strongly affected to electrical performance and instability in oxide TFTs. The oxide TFT on proper buffer layer/PI substrate showed better electrical performance than that on other buffer layers because the buffer layer with high gas diffusion barrier properties can suppress to generate defect states in semiconductor and/or interface from hydrogen and water penetration. The origins of flexible oxide TFT instabilities were systematically investigated by using in‐situ/ex‐situ measurement and chemical/physical analysis.

Published: July 2013

AbstractWe propose a method for multi‐domain vertical alignment of liquid crystals without additional transistors. By irradiating UV light to the polyimide through a patterned photomask, we can obtain different threshold voltage in a VA cell. There is no light leakage in the initial dark state so that the contrast ratio is not reduced in the proposed structure. We expect that the proposed method can be used to realize an eight‐domain structure for reduction of the off‐axis gamma shift
P.102: Improvement of Gamma Curve Distortion in VA LCD by using Optical Film Patterned Retarder
Authors: Mun Byung‐June , Jin Tae Young , Cho Jeong‐Ho , Lee Seung Hee , Lee Gi‐Dong 
Published: July 2013

AbstractIn this paper, we improved the γ‐curve distortion at off‐axis direction in a 4‐domain (4‐D) patterned vertical alignment (PVA) liquid crystal (LC) cell by applying a pair of the film patterned retarder (FPR) system with the A‐film property at the conventional wide‐view (WV) PVA LC cell. In order to achieve the excellent γ‐curve in the 4‐domain LC cell, we optimized the parameter of the pair of the patterned A‐film by using the two‐dimensional parameter space method, which calculates the polarization difference between the normal direction and the all viewing directions under voltage applied state. As a result, we confirmed that the gamma distortion index (GDI) of the proposed optical structure is reduced to over 80% without any loss of the optical luminance and the contrast ratio in the dark state.

Published: July 2013

AbstractA novel and efficient light extraction technique of OLEDs by attaching hierarchical micro‐pyramid array with antireflective nanostructures was demonstrated. The hierarchical micropyramid arrays were nanoimprinted on polycarbonate films by using silicon concave mold incorporated with micropyramid and nanoporous surface, which were made by alkaline texturing and nanoparticle‐catalyzed etching processes respectively. The additional antireflective nanostructures can effectively reduce the loss for the light normally incident at the inclined surface. After applying the subwavelength antireflective surface at the conventional micropyramids, the luminous efficiency enhancement was improved from 37.7% to 84.2%.
P.122: Optical Control of Surface Plasmon Loss in Transparent Organic Light Emitting Devices Coupled with Optical Compensation Layer
Authors: Mikami Akiyoshi , Ohashi Takuya 
Published: July 2013

AbstractLight extraction of transparent OLED can be improved by using an optical compensation layer on the back‐side of semi‐transparent metal cathode. From the results of detail optical calculation based on the multi‐scale analysis including near‐field optics, surface plasmon loss in semi‐transparent metal cathode was drastically suppressed to less than 10% due to the increase of wave‐vector caused by phase control of reflective coefficient of evanescent wave on the cathode interface. Not less than 90% of optical power in the dipole emission can be successfully utilized as the propagation light. The phosphorescent green light emitting device exhibits higher light extraction by a factor of about 1.5.

Published: July 2013

AbstractWe have demonstrated a new touch panel architecture that improve the touch sensitivity of stripe type projected capacitive touch panels.

By introducing dangling contacts to the sensing electrode close to the sense‐drive overlapping region, this effectively reshape the electric field over the region, and the contacts serve as extra antennas of E‐field that magnifies the touch effect. Such method would be particular useful for in‐cell touch technology due to the highly adaptability and the signal amplification effect.
