P‐6: A New Integrated Scan Driver using Oxide TFTs with Negative Threshold Voltage
Authors: Huh Jin , Cho Gyu‐Hyeong 
Published: October 2012

AbstractA new integrated scan driver composed of oxide TFTs with a negative threshold voltage is proposed for LCDs and AMOLED displays. By introducing a new circuit, which consists of two clock sets, SCLKs and PCLKs, with different low voltage levels and two DC voltage sources, VH and VL, the effect of a high off‐current of oxide TFTs at VGS = 0V was minimized and thus the scan driver showed stable operation by the negative threshold voltage of −2V. Furthermore, the proposed driver requires only two capacitors; therefore, it can be compactly implemented on a panel without additional increase of area. The operation of the proposed scan driver was fully verified by SPICE simulations.

P‐13: High Performance Ink‐Jet‐Printed TFTs on Solution Wetting Polymer Gate Dielectric Layer
Authors: Kang Woogun , Kitamura Masatoshi , Arakawa Yasuhiko 
Published: October 2012

AbstractWe have demonstrated high performance C60 thin‐film transistors by inkjet‐printing technology. C60 inks was jetted onto a polymer or self‐assembled monolayers gate dielectric layer, then vacuum‐dried to form uniform thin films. Inkjet‐printed C60 thin‐film transistors on a polymer gate dielectric layer showed an electron mobility of 1.6 cm2/Vs in operating voltage of 5 V. These results are attributed to high uniformity of vacuum‐dried C60 thin films and low charge trap density between C60 thin films and gate dielectric layer interface.

Published: October 2012

AbstractIn this paper, we analyze application of amorphous Indium‐Gallium‐Zinc‐Oxide thin film transistors (a‐InGaZnO TFTs) to voltage‐driven pixel electrode circuit that could be used for 4.3‐in. wide video graphics array (WVGA) full color active‐matrix organic light‐emitting displays (AM‐OLEDs). Simulation results, based on a‐InGaZnO TFT and OLED experimental data, show that both device sizes and operational voltages can be reduced when compared to the same circuit using hydrogenated amorphous silicon (a‐Si:H) TFTs. Moreover, the a‐InGaZnO TFT pixel circuit can compensate for the threshold voltage variation (ΔVTH) of driving TFT within acceptable operating error range.
P‐19: A New Small Sized Integrated Scan & Emission Driver for Compact AMOLED Displays
Authors: Huh Jin , Cho Gyu‐Hyeong 
Published: October 2012

AbstractA new small sized integrated scan driver for small sized and high definition LCD and AMOLED display is proposed in this paper. By introducing a new simple circuit, the number of output buffers (n) of a scan driver shares only one shift register. Therefore, the number of total shift registers is reduced by 1/n and thus total area for scan driver is significantly reduced by 40 %. By applying the proposed circuit, a new small sized scan & emission driver is also proposed. This driver can precisely control the initial time for sampling of threshold voltage of DTFT in a pixel. The proposed drivers were verified by SPICE simulation by using LTPS P‐type TFT models.

Published: October 2012

AbstractWe present a non‐IGZO based MOTFT with mobility beyond 53 cm2/Vsec, and with stability surpassing the numbers from high‐end SLA type LTPS‐TFT. The performance parameters allow one to make large‐size AMOLED TVs with all the future formats in discussion (e.g., 8Kx4K with 480 Hz frame time). Such high performance MOTFT can also be made on flexible substrate at low temperature. We thus provided a “dream” TFT technology sufficient to address all potential display applications in the foreseeable future, beyond a 10 year horizon.

Published: October 2012

AbstractWe characterized the subgap density‐of‐states (DOS)‐based reliability in hydrogenated amorphous silicon (a‐Si:H) thin film transistors (TFTs). Physical origins of the negative bias illumination stress (NBIS)‐induced threshold voltage shift (ΔVT) with wavelength‐dependence are quantitatively and systematically investigated. As a result, the photon energy is closely related to a creation of subgap states and the rate of ΔVOX (charge trapping into the gate insulator) /ΔVT is determined by the relation between the photon energy and the band offset. Our methodology is expected to be very useful for the development of next generation large‐area high performance active matrix liquid crystal display (AMLCD) technology.

Published: October 2012

AbstractIn this study, we presented new concepts defining 3D crosstalk and 3D blur for autostereoscopic displays for multi‐view autostereoscopic displays. First, we measured the angular dependencies of luminance for 9‐view autostereoscopic displays under test patterns of given view and then calculated the 3D crosstalk with the measured luminance profiles. Our new approach gives just a single 3D crosstalk value of similar order to the conventional stereoscopic displays. For the 3D blur, we measured the size of 3D blur of the given 9‐view system with the angular distribution of luminance and a given parallax disparity. From the results, we believe that this new approach is very useful for comparing the 3D crosstalk and 3D blur as 3D performances of various autostereoscopic displays.

Published: October 2012

AbstractTransmittance of conventional LCDs, which are not suitable for application of transparent displays, is limited by its fixed color gamut. A new structure of transparent display was developed to freely control the color gamut for tuning the transmittance. Its sub‐pixel was separated into two parts, colored & white, in order to control the transmittance of each part independently. The maximum transmittance could increase more than twice of original design. A vending machine with the transparent display has been demonstrated. People can see goods, get its information and interact with special program at the same time through touch with reasonable sense of space.

AbstractLCD panel with the LED backlight can be controlled by the proposed linear regulation control (LRC) technique for high efficiency and low cost. The LRC technique removes most of the external passive components, which include inductor, E‐cap, freewheel diode, and blocking diode. Due to single‐stage operation without two‐stage power consumption, small volume and high efficiency can be simultaneously ensured. Furthermore, the PLL function can guarantee the line voltage and current to be in phase so as to realize the high power factor (PF) for green power. High efficiency of 85% at 110Vrms and 87% at 220Vrms, high PF of 0.98 at 110Vrms and 0.96 at 220Vrms, and low THD of 18% at 110Vrms and 19% at 220Vrms are achieved.

P‐59: Starfield Contrast: A Quantitative Method to Determine the Contrast of Displays with Dynamic Backlights
Authors: Miseli Joe 
Published: October 2012

AbstractIn the ICDM DMS (Display Metrology Standard), we introduce a method to help quantify contrast for displays which have backlight dimming for low‐level drive levels — Starfield Contrast.LCD Displays with Dynamic Contrast (global/local dimming) reduce the output level of the backlights for display content with low average content. At the extreme (for all black or near black content) the backlight might be turned off, giving very high contrast values which might even be stated as infinite.Starfield Contrast determines the contrast of a display with global/local dimming at the threshold as the dimming circuitry begins operation. It controls the dimming to determine the real contrast of the display and provides the highest contrast before the display goes into its dynamic mode.

Published: October 2012

AbstractThe properties such as cell gap, pretilt angle and rubbing direction in the multi domain PS(polymer stabilized)‐VA cell were measured by a optical method. It has been impossible to measure the pretilt angle in sub micrometer area because liquid crystals in each area of the 4‐domain PS‐VA cell have different pretilt angle in the other direction. We could get the data using the optical measurement system merged microscope. Many failure muras caused during the liquid crystals process is analyzed successfully through the measurements. It is also very powerful tool to measure the cell gap below the protrusion in the pixel.

Published: October 2012

AbstractA backlight light‐emitting diodes (LEDs) accelerated life test method can indicate that the life time of the 20.1“/55” backlight LEDs are about 24,000/67,000 hours under around 2,000 hours test time. The accelerated life test estimates LEDs lifetime in normal use by operating LEDs at high environmental stresses. Generally, the homogenous LEDs life degradation behavior follows an exponential curve. The junction temperature (Tj) is the key factor for LEDs lifetime estimation. The empirical result of homogenous luminance exponential over‐time degradation is related with the junction temperature during ALT.
