Published: January 2009

AbstractWe developed the prototypes of 2‐view and multi‐view 3D displays based on LTPS 2.4″ VGA LCD panel with lenticular lens array sheets. In case of a 2‐view 3D, we attached the lens sheets, appropriate to a fine pitch LCD, in front of the panel. Throughout the advantage of high resolution, good 3D image quality was achieved with thinness and high brightness. for a multi‐view 3D, due to its large view number, smooth motion parallax and low visual fatigue are observed. From the results, we believe that the VGA LCDs with lenticular lens sheets are suitable for the application of the mobile 3D displays.

Published: January 2009

AbstractTo improve the efficiency of bend transition in OCB, its anisotropy was analyzed. The transition antiparallel (opposite) to the rubbing direction was significantly fast and this anisotropy remained at low temperatures. We propose two effects of LC shear flow on the anisotropy. Based on a pixel design that takes the anisotropy into consideration, 40% reduction of the initialization voltage in a 3‐inch TFT‐LCD has been achieved.

Published: January 2009

AbstractWe propose a new 2D/3D switching method using the lens effect solely caused by LC director distribution under controlled non‐uniform electric field distribution. By optimizing electrodes structure and applying this lens cell to LCD of 17.1 inches size in diagonal, we successfully verified the lens on/off effect of LC lens and the switching between an auto‐stereoscopic 9‐view 3D mode and a clear 2D mode. Comparing with previously reported structures of other switching lens, our proposed structure is the most competitive in respect of structure simplicity and process compatibility.

Published: January 2009

AbstractTo improve motion performance of ever‐larger LCD‐TVs, many manufacturers are turning to high speed driving to eliminate spatio‐temporal blur which arises due to hold‐type driving used in LCDs. This paper explores techniques being used to address motion blur in LCD‐TVs, describes various set/panel architectures which can be used to generate interpolated frames for high speed driving, compares different motion estimation methods, reviews some of the challenges which can arise in frame interpolation, and discusses the integrated motion interpolating TCON approach which is the most cost‐effective system for implementation of high speed driving.
26.2: Motion‐Adaptive Alternating Gamma Drive for Flicker‐Free Motion‐Blur Reduction in 100/120 Hz LCD‐TV
Authors: Kim Taesung , Ye Bo , Vu Chung Phan , Balram Nikhil , Steemers Hugo 
Published: January 2009

AbstractLCD motion blur is a well‐known phenomenon and several approaches have been developed to address it. This includes very high performing approaches based on Motion‐Compensated Frame‐Rate‐Conversion (MC‐FRC) and very low cost approaches based on impulsive driving. Impulsive driving schemes are attractive because of their low cost but suffer from two significant issues — loss of luminance and large area flicker. We propose a new impulsive driving approach using Motion‐Adaptive Alternate Gamma Driving (MA‐AGD) which removes motion blur and preserves the original luminance level without causing large area flicker.

Published: January 2009

Abstract120Hz driving using interpolated frames achieves better moving picture quality with less motion blur and less motion judder. However, errors in the interpolated frames can cause visual artifacts such as static text breakup, halos, and occlusions. This paper focuses on categorizing characteristics of visual artifacts and on reducing side‐effects by using information from original frames in special cases.

Published: January 2009

AbstractAromatic polyimide thin films are used as the alignment film in thin film transistor‐liquid crystal displays (TFT‐LCD's). The films play an important role in the initial alignment of the liquid crystal materials in LCD panels. Therefore, any structural or morphological deformation may lead to defect in the physical interactions thus malfunction of the display eventually. for example, an LCD is known to bear image sticking problem when it is assembled following 3 days or longer stagnancy in the process after main curing of the layer. In this paper, the molecular orientation of polyimide surfaces with respect to the stagnancy is investigated by means of surface sensitive Near Edge X‐ray Absorption Fine Structure (NEXAFS) spectroscopy. NEXAFS measurements clearly reveal preferred in‐plane and out‐of‐plane orientation of phenyl and C=O groups at the surface of the polyimide thin film in regard to the stagnancy after main curing. with longer stagnancy phenyl and C=O groups preferred in‐plane orientation. The preferred in‐plane orientation within the film can accelerate the image sticking problem in LCD's operating in PVA mode. Based on the result, vertical alignment of polyimide pendant group is found helpful for the better alignment of LC molecules in LCD's operating in the patterned vertical alignment (PVA) mode.
28.4: Late‐News Paper: Effects of Azimuthal Anchoring Energy on In‐Plane Switching Mode LCD
Authors: Lee Woo Keun , Park Hyun Jin , Lim Eun Jung , Shin Dong Cheon , Kim Dong Guk , Woo Joung Won , Shin Hyun Ho 
Published: January 2009

AbstractThe azimuthal anchoring energies (A.A.E.) of rubbed and UV‐exposed polyimides (PIs) alignment layers were measured more precisely by using improved optical measurement systems and modified cell configurations, and their effects on the alignment stabilities and liquid crystal (LC) response properties in an IPS‐mode LCD were studied. It is proved that (1) the relatively high A.A.E. is necessary for the alignment stability under high temperature stresses, and (2) the falling time of LC becomes shorter by about 0.7 ms with one order increase of an A.A.E. value. So we propose that the A.A.E. level of 1 × 10−2 ∼ 5 × 10−2 J/m2 is required for an alignment layer in an IPS‐mode LCD in order to guarantee the alignment stability and LC response property.

Published: January 2009

AbstractWe developed a 5.5 inch, VGA (640×480×RGB), stereoscopic 3D display using a wire grid polarizer on patterned retarder. The proposed stereoscopic display uses the existing TFT array panel and a color filter on a wire grid polarizer on patterned retarder. Since a wire grid polarizer is placed adjacent to the LC layer, there is no limitation on viewing angle and viewing distance. Therefore, it is possible for many people to watch stereoscopic display simultaneously.

Authors: Gu Mingxia , Shiyanovskii Sergij V. , Lavrentovich Oleg D. 
Published: January 2009

AbstractWe demonstrate for the first time that the dynamics of the nematic director during the turn‐off process can be accelerated by addressing the cell with a short voltage pulse of certain polarity. The duration of pulse is comparable to the time of dielectric relaxation of the nematic material and its polarity depends on the polarization created in the nematic bulk by the voltage applied during the turn‐on process.

Authors: Chen Hanfeng , Ha Taehyeun , Sung Junho , Han Baikhee 
Published: January 2009

AbstractAs a kind of hold‐type display, OLED panel also suffers from motion blur problem. A smooth frame insertion (SFI) method is proposed to reduce the motion blur on OLED panel. SFI method doubles frame rate by decomposing each original frame into a smooth frame and a compensation frame. The smooth frame is calculated by some low‐pass filter. By SFI, hold‐type display is converted to impulse‐like display and motion blur is reduced significantly without luminance lost and obvious flicker.

Published: January 2009

AbstractAs the mother glass size is increased and the high image quality is required, the relationship between the image quality and the glass surface becomes significant more and more. The nano‐scaled bump of the glass, so called a cord, a streak, and a thickness band is one of the main factors in the image quality. The LCD panel with the nano‐scaled bumps on the glass was fabricated and studied their effect on the image quality. In this paper, we introduced the mechanism for the degradation of the image quality caused by the relationship between the LCD's structure and the lens effect by the bump of the glass.

Published: January 2009

AbstractA novel 2‐stage analog amplifier with self‐compensated p‐type current loads for LTPS TFT‐LCDs is proposed. The proposed 2‐stage analog buffer has three phases for compensation. The first and second compensation phases are self‐compensation for the p‐type TFT active loads and third compensation phase is typical auto‐zeroing compensation for a 2‐stage buffer. This method can suppress the offset voltage generated by the mismatch of the current loads and input differential pair. We fabricated the proposed buffer using LTPS TFTs and measured its electrical characteristics. The measured maximum offset voltage is 10mV for the full output voltage to range.

Published: January 2009

AbstractThis paper describes an all‐digital phase‐locked loop (ADPLL) for system‐on‐glass (SoG) with low‐temperature poly‐Silicon (LTPS) thin film transistor (TFT). Due to the large variations and mismatches of LTPS TFT, it is very difficult to implement an analog PLL on glass substrate and ADPLL is employed for the timing generation in SoG. The ADPLL is implemented with a 2μm LTPS TFT process technology and consists of 5‐bit delay‐line time‐to‐digital converter (TDC), 7‐bit digitally controlled oscillator (DCO) and digital integrator. with a 20MHz reference clock, the ADPLL is locked within 36 periods of reference clock and shows 930ps peak‐to‐peak jitter.
