P‐210L: Late‐News Poster: Percolating Networks Improve Mobility in Organic Semiconductor Devices for Printed Electronics
Authors: Jain Ajaykumar R. , Powch George A. 
Published: July 2011

AbstractA novel method is presented to increase dramatically the effective mobility in organic semiconducting inks by embedding conductive nano/micro‐particles into the host matrix of typical organic inks. Such particles form percolating networks which effectively shorten the channel length in TFTs, greatly improving performance. Organic TFTs with such embedded percolating networks of Au micro‐particles were shown in a typical P3HT polymer semiconductor showing 5 X improvement in device mobility over reference OTFTs without such percolating networks.

Published: July 2011

AbstractThis paper proposes the flexible color R2R Ch‐LC e‐papers. By adding photochiral dopant, single substrate flexible Ch‐LCD becomes sensitive to UV light. Therefore, UV exposure can cause the discontinuous change in the helical pitch of the Ch‐LC pixels to colorize the e‐paper. After being colorized, the color e‐paper can be electrically driven to update the displayed content. Furthermore, the image could become more vivid. And the gray‐scale image also could become more detail. In this paper, the 75 dpi and 4 bits gray‐level color R2R Ch‐LC e‐paper is implemented.
P‐126: Tunable Lenticular Lens Array Using Liquid Crystal on Periodically Undulated Electrodes for Autostereoscopic 2D/3D Convertible Displays
Authors: Na Jun‐Hee , Park Seung Chul , Kim Se‐Um , Lee Sin‐Doo 
Published: July 2011

AbstractWe developed an electrically tunable lenticular lens array using a liquid crystal on periodically undulated electrodes for autostereoscopic 2D/3D convertible displays. The undulated electrodes fabricated through an imprinting and planarization process provide the focal length tenability of the liquid crystal lens. For 2D images, the uniform LC layer under no applied voltage produces no variations of the phase retardation over the whole area. For 3D images, the focusing capability arising from the electric field gradient generated by the undulated electrodes is achieved.

P‐129: A Novel Design of Ultra‐Wide‐View Patterned Polarizer for Stereoscopic 3D LCDs
Authors: Lee Chao‐Te , Lin Hoang‐Yan , Tsai Chao‐Hsu 
Published: July 2011

AbstractThis study presents a new methodology to design the patterned circular polarizer comprising a linear polarizer, a patterned retarder and a biaxial film for stereoscopic 3D LCDs. Based on the existing biaxial compensation technique, the patterned polarizer with biaxial compensation rather than conventional ±λ/4 patterned polarizer can enhance wide‐view performance by using the same patterned alignment technique. Compared to the conventional ±λ/4 patterned polarizer compensated by positive C film, the maximum crosstalk ratio of the optimal structure reduced from 0.025 to 0.018 at ±60° viewing cone for light normally passes through the glasses, and from 0.09 to 0.065 at ±60° viewing cone for light obliquely passes through the glasses at the angle the same as the one passing through LCD.

AbstractWe present a vertically aligned nematic liquid crystal mode characterized by micro‐lens‐array type surface morphology. The proposed VA mode is focused on obtaining high transmittance with omnidirectionally uniform optical image. In this proposed cell structure, when electric field is on, an azimuthally continuous nematic domain is produced in a pixel. This LCs behavior can improve the optical properties, compared with the conventional VA modes.

Published: July 2011

AbstractWe demonstrated the stabilization of blue phase (BP) liquid crystal by doping the colloidal particles. Temperature range studies were conducted with imaging through the polarized optical microscope (POM). The BP liquid crystal temperature range was increased up to 3.1°C with 0.76% colloidal particles in BP, and then decreased with increasing concentration of colloidal particles in the BP mixture. Reflectance measurements showed the greatest wavelength shifting occurred with 1.84% colloidal particles in BP mixture. In the field‐induced optical Kerr effect, the optimization in the colloidal particles doped BP LC device also decreased in threshold voltage (Vth) from 34.2V of non‐doped BP LC, to 32.2V of the doped BP LC.

AbstractPolymer stabilized blue phase (PSBP) with different chiral pitch was prepared to investigate the relation between electro‐optic response and the chiral pitch of PSBP. The stabilized temperature ranges of each PSBP were around 100 K. The effect of the chiral pitch of PSBP on the Kerr constant and the response time was almost same with the result of pure blue phase (BP) that is the Kerr constant of PSBP was proportional to the cube of the chiral pitch.

P‐155: Analysis of Solubilization of Surface‐Modified Carbon Nanotube in Nematic Liquid Crystal Using Flory‐Huggins Theory
Authors: Huang Kevin Y. C. , Fuh Andy Y. G. 
Published: July 2011

AbstractAn analytic study on the solubility behavior between 4′‐n‐pentyl‐4‐cyano‐biphenyl (5CB) liquid crystal and Maleic anhydride (MA) grafted surface‐modified single walled carbon nanotube (CNTs‐MA) using the prestigious Flory‐Huggins model is presented. The statistical thermodynamics of the Flory‐Huggins mean‐field theory is for the first time, applied in the solubility study of the ill‐famed issue of blending liquid crystals with carbon nanotubes. In conjunction with the Monte Carlo calculations, we discovered that at room temperature, this functionalized carbon nanotube can dissolve in the 5CB nematogens when the grafting ratio of the MA functional groups reaches up to 20 atomic wt%. Although it may not be for a perfectly exact prediction with respect to the mixture of liquid crystal combined with carbon nanotubes, we believe this mesoscale simulation can still offer reliable tends and directions toward the analysis of designing “liquid crystal‐soluble” carbon nanotubes in order for this novel composite to become a practical homogeneous nanosolution, and realize its promises in the future.

AbstractWe propose a novel method for a stable four‐domain twisted nematic (4DTN) structure by injecting nematic liquid crystal in an isotropic phase under an applied electric field. In this method, no high pre‐tilt angle is required to stabilize the 4DTN structure and thus the high transmittance and fast response are obtained.
P‐159: Slit Pattern for Dynamic Stability of TN‐VA LCD
Authors: Chen Xiaohui , Cui Hongqing , Chung Te‐Chen , Jen Tean‐Sen 
Published: July 2011

AbstractWe investigated the dynamic stability of disclination lines (DLs) generated near the boundary of adjacent domain with different Liquid crystal orientation in the conventional multi‐domain twist nematic‐vertical alignment (TN‐VA) LCDs. The Liquid crystal molecules collide with each other at the reverse twist boundaries due to the strong reverse twist force competitions at a high voltage, and pushes DLs deeply penetrate into the active region, resulting in a decreased transmittance in the panel. To ameliorate these drawbacks, the slit pattern was induced at the location of reverse‐twist boundary with the function to suppress the reverse twist force and eliminates the distortion, thus make DLs remain very slim near boundary areas. As a result, the transmittance dynamic stability is greatly improved.

AbstractA new transflective OCB‐LCD with an in‐cell compensation film in the reflective part was proposed to improve a brightness and viewing‐angle performance of the low‐voltage driving transflective LCDs. We verified that wide viewing angle range exceeding ±80° (CR >10:1), a high contrast ratio over 1000:1 and comparatively high luminance (normalized transmittance >0.75 and reflectance >0.65) could be achieved in both transmissive and reflective parts by optimizing design parameters of the LCD, even if the on voltage is lowered to 3.5V.
P‐166: Successive Cross Emission Driving for 3‐Dimensional Active‐Matrix Organic Light Emitting Diode Displays
Authors: Park Hong‐Sik , In Hai‐Jung , Oh Kyong‐Hwan , Kwon Oh‐Kyong 
Published: July 2011

AbstractWe propose a pixel structure and its driving scheme for stereoscopic 3‐dimensional (3D) active‐matrix organic light emitting diode (AMOLED) displays. The proposed pixel structure and its driving scheme have merits that are longer emission and programming time than simultaneous emission scheme by successive cross emission of left and right images. Moreover, it can reduce flicker by reducing interval between emission times. For 3D AMOLED displays of 40‐inch full high definition TV (1920×1080), the emission current error rate of the proposed pixel structure is from −0.961% to 1.013% when the threshold voltage variation of driving TFT varies from −0.8 V to 0.8 V, and that the error is less than 2% when the VDD‐IR drop voltage becomes 2.0 V.

AbstractTransparent OLEDs offer great potential for novel applications. Preferably, the light should be emitted from one side only.

Authors: Zakhidov Alex A. , Lüssem Björn , Leo Karl , DeFranco John 
Published: July 2011

AbstractThe structurization of organic thin film devices is a challenge, since they are usually incompatible with standard lithography processes. Here, we report on the influence of a fluorinated solvent on the performance and lifetime of small molecule organic light emitting diodes (OLEDs). An initial test right after processing shows only a marginal difference between treated devices and reference device. Luminescence decay curves to 90% brightness (LLT90) data confirm that no long‐term damage with respect to the reference sample occurs. LLT90 for treated sample approaches 100,000 hours, which makes this solvent acceptable for wet chemical processing such as photolithography.

Published: July 2011

AbstractA fast response Dual Finger Electrode Liquid Crystal Lens DFE‐LC lens which could provide dual directional overdriving method was proposed. By the proposed controlling sequence, the vertical and lateral electric fields could be obtained simply to reduce the focusing time as well as recovering time of LC lens, respectively. Therefore, the response time tfocusing and trecovering could be further reduced to 2s, which was much faster than current LC lens∼ 8s. In addition, the proposed LC lens could apply not only for fast switching 2D/3D display but also for potential high resolution 3D display with scanning LC lens.
