P‐159: Decomposable Alkali Compounds for Transparent Cathodes in OLEDs
Authors: Duan Lian , Qiu Yong , Zhang Guo Hui , Song Liu , Ren Xue Yan 
Published: August 2010

AbstractEfficient top‐emission and transparent OLEDs with decomposable alkali compounds as the electron injection layer have been developed. The alkali compounds, such as alkali nitrides and carbonates, decomposed during vacuum thermal evaporation to liberate alkali metals. Therefore, inert metals such as Ag can be used as the rear cathode. Top‐emission device with Li3N/Ag cathode showed a turn on voltage of less than 3.0 V, a current efficiency of 8.3 cd/A and a brightness of more than 105 cd/m2 at 10 V. Our study shows that alkali/Ag cathode is an excellent candidate for transparent cathode in top emission or transparent devices.

AbstractWe investigated the effectiveness of p‐dopants such as CuI, MoO3 and ReO3 having different work functions to generate holes in a hole transporting material of 4,4′,4″‐tris(N‐(2‐naphthyl)‐N‐phenyl‐amino)‐triphenylamine (2TNATA). Dopants with larger work function (ReO3>MoO3>CuI) are more effective in the formation of CT complexes and in the generation of the charges.

Published: August 2010

AbstractPreviously, we reported two optical structures for bottom‐emitting white OLED, exhibiting wide color gamut (> 100% NTSC) and high (> 40%) transmission through color filter. The panels employed RGBW color system for efficiency. The color shifts at oblique angles for the individual R, G, B, and R+G+B were maintained below Δu'v' < 0.02@ 60°. However, the colors produced by the combination of R/G/B subpixels and W subpixels exhibit large color shift when viewed at oblique angles because the luminance profiles, as a function of viewing angle, of the R/G/B which employ strong resonance, and the W which has weak resonance, are very different. In this report, we present a novel optical architecture for the W‐subpixel. The color shift for the W‐ subpixel was reduced from Δu'v' = 0.059 to 0.026 and the luminance profile was much closer to those of R/G/B subpixels. The efficiency of the W‐subpixel with the new structure was on the same level as that of the conventional, plain, weak‐resonance structure.

Published: August 2010

AbstractA novel displaying method, two‐color‐field driving scheme, was proposed for field‐sequential‐color LCDs without color filters. The least number of fields alleviated the demand for fast response LC modes in sequential‐type LCDs. The proposed method reproduced full color images with acceptable colorimetric reproduction accuracy, average ΔE00ave<3. Furthermore, less chrominance difference between the two fields was beneficial to suppress color break‐up.

Published: August 2010

AbstractPhotoluminescence(PL) characteristics under vacuum ultraviolet(VUV) region of Tb3+ doped yttrium aluminium borate phosphor were investigated for Plasma Display panel(PDP) application. The single‐phase green emitting Y1−xTbxAl3B4O12(YAB: Tb3+) powder phosphors were prepared with various Tb3+ ion concentration. As a result, the intensity around 147nm of excitation spectrum in YAB: Tb3+ decrease slightly with increase of Tb3+ ion concentration due to concentration quenching behavior, but on the contrary, the intensity of 172nm increase with increase of Tb3+ ion concentration due to attributing the 4f8 → 4f7 5d1 transition of Tb3+ [1]. However in the result of gas discharge chamber test which has the same gas mixture as real PDP, relative PL luminance of YAB: Tb3+ increase with increase of Tb3+ ion concentration due to effect of increasing absorption at 172nm. Besides, YAB: Tb3+ with high Tb3+ ion concentration (x=0.7) has higher VUV luminance saturation property than low Tb3+ ion concentration (x=0.4) since high Tb3+ ion concentration phosphor has more activators than lower one which can react with VUV photon in unit volume.

AbstractAn area‐effective 12‐bit linear digital‐to‐analog converter (DAC) of source driver is proposed for large‐Size TFT‐LCDs. The proposed DAC is composed of resistor‐string DAC for MSB 6‐bit, current DAC for LSB 6‐bit and interpolation amplifiers. To reduce the area of DAC, 6‐bit current DAC is designed using low voltage devices. We designed and fabricated the source driver with the proposed DAC using 0.13 μm process with 2.5 V low voltage devices and 16 V high voltage devices. One channel layout area is 17.5 μm × 600 μm, which is shrunk by 15% compared with that of 8‐bit resistor‐string DAC. The experimental results show that the output voltage deviation is less than 3.5 mV.

Published: August 2010

AbstractHighly efficient and stable white PIN OLED structures based on Kodak's proprietary emitters and Novaled's proprietary p‐ and n‐type dopants have been developed with a focus on AMOLED display applications. At color coordinates of 0.33/0.36, a current efficiency of 15.1 cd/A at a voltage of 3.0 V was achieved at 1000 cd/m2 brightness. The lifetime of this device is 27,000 hours at a starting luminance of 1000 cd/m2. The spectrum of the devices contains a contribution from four emitters (RGBY) and the emission of the presented OLED structures is therefore ideally suited for use in RGBW AMOLED displays. with variations of the blocking layers, the device efficiency can be increased to 16.8 cd/A, which corresponds to an external quantum efficiency of 7.3%. The results in this paper are based on a joint research effort between Eastman Kodak Company and Novaled.

AbstractChunghwa Picture Tubes LTD. has successfully developed the 2.8‐inch TN‐type mobile hi‐resolution TFT‐LCD module using color‐sequential driving method in 5‐mask a‐Si Processes. DT‐LPAD structure is designed specially for the mobile hi‐resolution TFT‐LCD, which can make the data addressing period and BRD addressing period overlapped in color‐sequential driving period. Due to the overlapped driving, we can attain the scanning‐BL driving method and four fields driving methods to improve the efficiency of transmission and to reduce color‐breakup phenomenon. Hence, the driving frequency and power consumption are reduced directly and the display shows better quality. The main features of our mobile hi‐resolution display module include 480 × 640 resolution, TN Type Liquid Crystal (Response Time is less than 5ms by high speed TN LC and low cell gap), wider color gamut and high color expression characteristic (NTSC 96%), and the BL power consumption is similar to commercial 2.8‐inch TFT‐LCD.

AbstractNovel p‐dopants of ReO3 and CuI, and an n‐dopant of Rb2CO3 have been developed. Among many other p‐dopants, ReO3 possesses superior characteristics of low temperature deposition, efficient charge generation and increasing the device lifetime. The absorption intensity of CT complexes and current‐voltage characteristics revealed that charge generation in p‐doped hole transporting layers is more effective when the work function of the dopant is larger.

AbstractA power‐efficient and stable organic light emitting diode with a simplified structure based on 2‐methyl‐9,10‐di(2‐naphthyl)anthracene (MADN) has been developed.

Published: August 2010

AbstractIn this work, a novel nanogap with inclined protrusion cathode in palladium strip fabricated by hydrogen absorption under high pressure treatment is optimized for the surface conduction electron emitter. The results of our previous study had shown that the field emission property of the tested structure is superior to conventional one with a coplanar cathode. for a specified emitter material, the surface conduction electron‐emitters (SCE) are further investigated by varying the thickness, tilted angle and gap of palladium (Pd). An optimal field emission efficiency with 80° tilted angle, 120 nm gap and 10 nm thickness of Pd is found for certain designed field emission efficiency. We further find that varying the emitter material work function of the emitter material from 5.12 eV to 3.9 eV will further improve the field emission property due to the increase of the emitted current.

41.1: Viewing Direction Controllable Three‐Dimensional Display Based on Integral Imaging
Authors: Park Jae‐Hyeung , Shin Minyoung , Kim Nam 
Published: August 2010

AbstractA novel method to control the viewing direction of the integral imaging based three‐dimensional display using the 4‐f illumination optics is proposed. Based on integral imaging principle, the light from the point light source array is modulated by the spatial light modulator, displaying three‐dimensional images. The viewing direction of the three‐dimensional image is determined by the diverging direction of the light emanating from each relayed point light source. In the proposed method, a 4‐f optics with a dynamic aperture in the Fourier plane relays the point light source array to the spatial light modulator. The dynamic aperture acts as a band‐pass filter in the Fourier plane, effectively controlling the diverging direction of the light from the point light sources. Resultantly, the proposed system can control the viewing direction of the three‐dimensional image dynamically. The proposed method can be combined with the head tracking system, providing the three‐dimensional image over large viewing angles.
