P‐148: Temperature Dependence of Degradation in Organic Light‐Emitting Diodes
Authors: Kondakova Marina E. , Young Ralph H. , Jarikov Viktor V. , Giesen David J. 
Published: August 2010

AbstractProlonged operation of an OLED degrades the luminance and alters the voltage‐dependent capacitance. The loss of luminance in simple blue and green fluorescent OLEDs is linearly correlated with internal charge accumulation at the HTL|LEL interface. The shapes of the EL decay curve and the transition‐voltage‐rise curve are independent of temperature. Proper scaling of the time axis makes plots of EL or transition voltage vs. time at different temperatures to coincide. The resulting universal decay curves are not altered by the introduction of the fluorescent dopant, suggesting that the degradation processes are the same in the doped and undoped devices. Red fluorescent OLEDs of more complicated structure degrade in a dopant‐dependent manner.

Authors: Lee Meng‐Ting , Lin Jin‐Sheng , Chu Miao‐Tsai , Tseng Mei‐Rurng 
Published: August 2010

AbstractEmploying double emission layers (DELs) into blue phosphorescent organic light‐emitting devices (PHOLED), the device shows improved current efficiency by a factor of 1.8 compared to that of device using single emission layer (SEL). Furthermore, by doping additional carrier‐transporting material into DELs, the device shows a slight efficiency roll‐off of 24% from low (1 mA/cm2 and 400 cd/m2) to high current density (40 mA/cm2 and 10000 cd/m2). The dramatic improvement in device performances can be attributed to the formation of a broader carrier recombination zone and the elimination of carrier accumulation at interface. A blue PHOLED with a current efficiency of 29.5 cd/A, a power efficiency of 21 lm/W and a low driving voltage of 4.4 V with a CIEx,y of (0.16, 0.35) at a practical brightness of 1000 cd/m2 can be achieved.

AbstractGas diffusion barriers based on nanolaminates of alternating Al2O3/ZrO2 layers prepared by atomic layer deposition at 80 °C are presented. Water vapor permeation rates as low as 4.7×10−5g/(m2 day) are determined (at 70 °C and 70 % rh). Compared to single Al2O3 encapsulation layers, a reduced density of statistical defects is found. The reliable nanolaminate encapsulation is demonstrated by OLED lifetime measurements.

Published: August 2010

AbstractColor break‐up (CBU) is a lethal issue of a high light efficiency field‐sequential‐color (FSC) LCD. Applying local color‐backlight‐dimming technology to FSC‐LCDs, we demonstrated “Stencil‐FSC” methods with a field rate as low as 120Hz to render a high luminance “multi‐color” image on the first‐field and effectively suppress CBU at the same time. In addition, the color filterless LCD with an intelligent LED backlight and even non‐polarized LC cell, optical thruput can increase by a factor of 10, yet with lower material cost/count for an Eco‐Display.

18.5L: Late‐News Paper: Liquid Crystal Privacy‐Enhanced Displays for Mobile PCs
Authors: Ishii Junichiro , Saito Goro , Imai Masao , Okumura Fujio 
Published: August 2010

AbstractWe have developed a 12.1‐inch, XGA Liquid Crystal Privacy‐Enhanced Display for mobile PCs. Only an authorized viewer with shutter glasses can see a private image while other viewers see a public image. The privacy enhanced display system is based on a high‐frame rate image switching technology. In general, it is difficult for LCD to achieve the high speed image switching because of its slow response speed. A high speed driving scheme and a high frame rate overdriving method made it possible to realize this function in LCD.

Published: August 2010

AbstractWe report on the development of low‐temperature gate dielectric materials for zinc indium oxide (ZIO) thin‐film transistors (TFTs). Several films, including ALD HfO2 and PECVD SiNx (deposited at 175°C and 150°C, respectively), yield good TFT performance. Bias stress‐induced threshold shift for HfO2 is quite small, however does not follow conventional trends associated with hydrogenated amorphous Si (a‐Si:H) TFTs; PECVD SiNx conversely, shows bias stress characteristics that conform reasonably to a model appropriate for a‐Si:H devices.

Published: August 2010

AbstractThe frequency response of cholesteric liquid crystal display (ChLCD) and its application in the driving system of colored ChLCD were developed. The R‐V curves were shifted 4 volts by 10 Hz ∼ 500 Hz frequency modifications for a ChLCD with no adhesion layer. However, the R‐V curves were shifted 12 volts by 10 Hz ∼ 500 Hz frequency modifications for a ChLCD with the 1.5μm adhesion layer. The shift of the R‐V curves between different frequencies was dependent on the existence of an adhesion layer and the material of substrates. The root cause of such a frequency response was due to the ChLCD structure in which the induced charges were dependent on the frequency of applied voltages. The R‐V curves of different colored ChLCs could be overlapped with each other by utilizing the frequency response. Consequently the new driving waveforms were proposed for the colored ChLCD, and the cost of DC‐DC converters for the scan driver ICs could be reduced 66 % in this proposed driving system.
23.1: Invited Paper: Luminescence Quenching by Charge Carriers in Organic Light‐Emitting Diodes
Authors: Wyman Millard , Marchetti Alfred , Rothberg Lewis , Young Ralph , Kondakov Denis 
Published: August 2010

AbstractWe report photoluminescence quenching studies on model DCJTB‐doped Alq3 electroluminescent devices. The spectroscopy versus doping density suggests that solvatochromic effects are minor but that energy transfer plays a large role. Quenching of DCJTB fluorescence is due to Förster energy transfer to DCJTB cations, and measurements of the bleaching recovery dynamics show that charge extraction from ionized DCJTB sites is slow and consistent with biexponential kinetics. Temperature‐dependent studies find effective activation barriers for detrapping that are too small to be consistent with simple HOMO offsets between host and dopant.

25.1 Invited Paper: High Resolution Autostereoscopic 3D Display with Scanning Multi‐Electrode Driving Liquid Crystal (MeD‐LC) Lens
Authors: Huang Yi‐Pai , Chen Chih‐Wei , Shen To‐Chiang 
Published: August 2010

AbstractAn autostereoscopic display with full resolution of2D and 3D images with wide viewing angle potential was proposed by combining an “active scanning film” and fast response OLED. In order to realize the active scanning film to project the images to different directions sequentially, Multi‐Electrode Driving Liquid Crystal (MeD‐LC) Lens was utilized. Comparing with traditional LC lens structures, MeD‐LC lens could not only be switched on/off, but also horizontally moved to “scan” and project images. Additionally, MeD‐LC lens was more competitive in respect of structure simplicity and various curvature generations.

Published: August 2010

AbstractThe characteristics of the MgO layer are known to be an important parameter that affects both the address and sustain discharge characteristics in an ac‐PDP. In this paper, to improve the discharge characteristics of 50‐in. full‐HD ac‐PDP with He (35%) ‐ Xe (11%) contents, RF‐plasma treatments on the MgO layer are examined under various gases for plasma treatment. The resulting changes in the address and sustain discharge characteristics, including the firing voltage, Vt closed curve, power consumption, luminance, luminous efficiency, and secondary electron coefficient, are then compared for both cases with and without plasma treatment on MgO layer. It is concluded that the Ar plasma treatment can enhance the discharge characteristics, such as the firing voltage and power consumption, which are caused by an increase in the secondary electron coefficient.

AbstractWe report high‐efficiency fluorescent red OLEDs with 11.5% EQE (15 cd/A) at 3 V, and yellow OLEDs with 8.6% EQE (28 cd/A) at 2.9 V. This performance was obtained using a nonemitting assist layer adjacent to the emission layer, and low‐voltage electron‐transporting and electron‐injecting layers. Time‐resolved electroluminescence measurements indicate a significant efficiency contribution (up to 50%) from triplet—triplet annihilation processes.

AbstractA panel manufacturing process for multi‐color electrowetting display (EWD) by using ink‐jet printing (IJP) technique had been developed. To achieve multi‐color, two strategies were used, i.e., by using black oil with color filter and by using various colored oils without adopting color filter. for colored oils, various dyes had been used to blend with alkane solution. Then, the jetting behavior of different colored oil for IJP was investigated. Here, a 6‐inch multi‐color EWD prototype with black oil and color filter was successfully fabricated, and a dual color EWD panel with black and red oils had also been first evaluated.

AbstractThe electron and hole supply into the recombination zone of an OLED is of crucial importance to achieve optimum performance. By adjusting the energetic levels of the transport and the blocking layers we optimize lifetime and power efficiency of blue and red fluorescent PIN OLEDs. for a red OLED, we achieve 100 cd/m2 below 2 V. By deliberately introducing barriers in the electron supply of red fluorescent OLEDs, we can “switch on” triplet‐triplet annihilation, leading to a significant boost in efficiency — up to 12 % external quantum efficiency were measured in an integrating sphere.

AbstractThe Pixtronix DMS™ (Digital Micro Shutter) display technology intrinsically provides exceptional image quality due to its optical architecture and device technology. This technology, based on MEMS micro‐shutters formed on active TFT backplanes, has enabled the development of color sequential, time division gray scale, direct‐view displays achieving breakthrough performance ‐ including 150% NTSC (CIE 1976 u'v' color space) color gamut, 24‐bit color, > 500:1 contrast ratio and 170° viewing angle, all at 1/4 the power consumption of comparable TFT‐LCD display modules. In addition to this, these displays present horizontal contrast viewing angle comparable to that of OLEDs providing exceptional color saturation in large angle viewing directions. This paper will briefly describe the Pixtronix DMS™ display technology. It will also describe key display architecture elements of DMS technology responsible for the excellent optical performance. The optical characterization of prototype displays and discussion of the results will be presented. A non‐emissive technology like DMS technology is able to provide performance close to that of emissive technologies like OLED at a power much lower than that of an LCD display.

AbstractWe describe a transfer printing method for patterning of thin polymer layers. A hard stamp with raised feature is brought into contact with a spin coated organic film under elevated pressure and temperature to break the films. The patterned film is then transfer printed onto devices. We use this method to print red/green/blue sub‐pixel arrays with pattern size as small as 12 μm at a resolution of 530 ppi to demonstrate its ability for full‐color organic light‐emitting display fabrication.

AbstractUsing a 4‐viewer Autostereoscopic 3D Home Theater display system, a radically designed projection screen film system coupled with a conventional projection display is herein presented and shown to produce a superior 3D effect than most current autostereoscopic and non‐autostereo 3D Display systems. The proposed design's goals were specifically aimed at tackling the, until now, mutually exclusive properties of most parallax based autostereoscopic 3D Displays i.e. staggeringly high Display Optical Efficiency and drastically low levels of image Crosstalk. By uniquely patterning a film stack onto a projection screen so that the projected left and right images are reflected to their respective viewers locations without the need for barrier or lenticular lens, we were able to achieve a 0% Image Crosstalk at ∼90% Optical Efficiency in a 4 concurrent autostereosocopic 3D viewers Home Theater Display System.

Published: August 2010

AbstractThis paper proposed an autostereoscopic 3D projector composed of LCD projectors and two parallax barriers located beside the two sides of the projection screen. Parallax barrier 1 facing to the projectors acts as the function of collimating the images which have aberrations on the edge of the projection screen. Parallax barrier 2 facing to viewers acts as the functions of the parallax barrier in ordinary autostereoscopic 3D displays. The operation principle of the system and the calculation equations for the parallax barriers, the capture and correction of images were described in details. A 60‐inch autostereoscopic 3D projector prototype having four projectors was developed. The prototype has high resolution and sharp stereoscopic image presentation.
