P‐4: Effects of Surface Polarity on Nematic Liquid Crystal Alignment
Authors: Kim Young Ju , Bae Jin Woo , Song Kigook 
Published: July 2014

AbstractAlignment of liquid crystal molecules on a polymer substrate depend on various molecular interactions at the interface between liquid crystal and substrate, such as dispersion forces, dipolar interactions, steric interactions, hydrogen bonding, and physical interactions due to distortion of orientation field of liquid crystals by grooved surface of the substrate. Among these interactions, dispersion force is regarded as a long‐range interaction and other interactions are regarded as short‐range interactions which do not extend beyond a few tens of angstrom. The homeotropic alignment mechanisms for nematic liquid crystals were studied on oxygen plasma treated glass substrates. The homogenous alignment was obtained for positive nematic liquid crystals whereas the homeotropic alignment for negative liquid crystals. Our studies provide experimental evidences showing that there is competing forces to determine the orientation of liquid crystals, and alignment can be controlled by adjusting the substrate polarity. Relations between anchoring transition of liquid crystals and the polarity of substrates were studied by observing liquid crystal alignment directions using polarized optical microscopy, conoscope, and FTIR spectroscopy. These studies provide experimental evidences showing that short‐range dipolar interactions and long‐range van der Waals interactions competitively control the orientation of the LC director.

AbstractWe have developed pseudo‐CMOS circuits using α‐ITZO TFTs. The pseudo‐CMOS circuits have more excellent circuit characteristics than the conventional circuits. Either of the two pseudo‐CMOS circuits should be selected on demand by considering whether the static or dynamic characteristic is important. These results are useful to integrate driver circuits into FPDs.
P‐7: High Speed a‐IGZO TFT‐based Gate Driver by using Back Channel Etched Structure
Authors: Um Jae Gwang , Mativenga Mallory , Geng Di , Li Xiuling , Jang Jin 
Published: July 2014

AbstractWe demonstrated the high performance back–channel‐etched (BCE) amorphous‐InGaZnO (a‐IGZO) thin‐film transistor (TFT) circuits. The TFTs exhibited the field‐effect mobility, turn‐on voltage and subthreshold swing of 18 cm2/V•s, ‐0.1 V, and 258 mV/dec, respectively. The oscillation frequency of an 11 stages ring‐oscillator is ~334.1 kHz, at VDD = 20 V. The 320 stages 11T2C shift‐register operated well up to the last stage with rising and falling times of 950 and 690 ns, respectively. Good performance is attributed to damage‐free back channel wet etch process and small overlap capacitance between the gate and source/drain electrodes.

Published: July 2014

AbstractIn this work, the relation between post annealing temperature and electrical characteristic on high mobility a‐IZTO TFTs was investigated. The 400°C‐annealed a‐IZTO TFTs exhibited a better performance with field effect mobility of 39.6 cm2/Vs, Vth of ‐2.8 V and sub‐threshold swing of 0.25 V/decade. Both shallow trap states of a‐IZTO film and interface trap states at the a‐IZTO/SiO2 interface decreased to 2.16 × 1017 cm−3eV−1 and 4.38 × 1012 cm−2eV−1, respectively with 400°C annealing. Owing to the higher energy from annealing process, the structural relaxation can be enhanced leading a better electrical characteristic of a‐IZTO TFTs.

Published: July 2014

AbstractThis work presents a comparative analysis of top gate a‐IGZO TFTs fabricated on both soda‐lime‐silica glass and alkali‐free borosilicate glass. Low‐temperature ALD is selected for the deposition of gate dielectric to minimize a thermal stress. Comparing with TFTs on alkali‐free borosilicate glass, TFTs with soda‐lime‐glass show similar threshold voltage and sub‐threshold swing, but slightly degraded effective mobility, stability and uniformity. The results of atomic force measurements are provided to explain the uniformity degradation.

Published: July 2014

AbstractA new gate driver composed of amorphous In‐Ga‐Zn‐O (a‐IGZO) thin‐film transistors (TFTs) is proposed. By turning off TFTs completely to suppress the leakage current and eliminating the unnecessary charge and discharge currents, the power consumption of the proposed gate driver is reduced. Simulation results indicate that the proposed gate driver can be operated successfully with depletion‐mode a‐IGZO TFTs and the power consumption is reduced by 18.9% of the previously reported result.
P‐28: Study on One Infrequent Influencing Factor of TFT‐LCD Life
Authors: Feng Bin , Huang Hai‐Qin , Cui Xiao‐Peng , Yuan Jian‐Feng , Shao Xi‐Bin 
Published: July 2014

AbstractThrough a lot of analysis and test on a rare failure (ongoing black mura), we found that the distance of TFT U shaped channel to the gate line edge have great influence on the stability of TFT device. When the distance is less than a critical value, the characterization of TFTs would degrade after a long‐time of stress or aging, lead to decrease of Ion and increase of Vth, resulting in poor life time of TFT‐LCD for the abnormal black phenomenon. By BTPS(Bias, Temperature, Photo, Stress) [1‐2] and aging test, we compare the stability of TFTs with different distance value, establish calculation model and design spec. Effective improvement have achieved by process adjusting and design changes.

Authors: Akşit Kaan , Niaki Amir Hossein Ghanbari , Urey Hakan 
Published: July 2014

AbstractThis paper introduces a new major milestone on stereoscopic displays, where users no longer suffer from the accommodation‐vergence conflict problem with a perfected monocular parallax. Our method provides multiple views to a single eye by using special apertures equipped with filters in front of the user's eyes in which the design is embedded into conventional stereoscopic glasses or special stereoscopic contact lenses. Thus, visual fatigue originated from accommodation‐vergence conflict is avoided. Through informal subjective tests, we have shown that the depth perception, accommodation, and vergence of the eyes can be enhanced. The technique is also capable of converting multi‐view displays to Super Multi‐View (SMV) displays.

Authors: Zhong Xuefei , Tu Yan , Niu Wenjuan , Guan Zhuangzhuang 
Published: July 2014

AbstractTo understand actual viewing conditions at home is important for lighting and TV design or program broadcast. The preferred luminance level of LCD TVs under actual viewing conditions is also important in order to obtain both good picture quality and low power consumption. Chinese's viewing environment and behavior at home are investigated in this paper. The results show that when the viewers watch TV in the daytime, the ambient illumination fluctuates with the time and weather. While at night, the intensity of ambient illumination is relatively dim, which reflect the lighting requirement of most viewers. The viewing distance is between 180cm to 350cm which is 4 to 9 times of the screen height. For most families, the watching time is lower than 3 hours per day. The first three favorite programs are series, news and entertainment program.

Published: July 2014

AbstractAdvances in display technology depend on our ability to develop miniscule elements that emit a broad range of light intensities and colors. Existing technologies are limited and face trade‐offs between producing luminance and color. Photometry and colorimetry provide tools to help developers understand those trade‐offs and to set meaningful targets for the future. Uncertainty remains however as to which metrics provide the best guidelines. We examined the relationship between 8 color metrics and human preferences for displays that differed only in color gamut. We found that (1) volume metrics, computed from display luminance and color capacity, outperformed area metrics computed only from color and (2) of the color metrics we considered, CIECAM′02 saturation best predicted viewer preference.

After only three trials performed by users, it is possible to estimate the OD values for all the transitions of the LCDs.
P‐37: Readability of Displays in Bright Outdoor Surroundings
Authors: Andrén Börje , Brunnström Kjell , Wang Kun 
Published: July 2014

AbstractReadability of displays in bright outdoor surroundings is a problem for many types of visual displays. The wide range of lighting conditions that these displays should be able to operate in, makes the design of the test set‐up very challenging. Mobile displays of today usually have LCDs with LED backlight or OLEDs, which gives the possibility to control the light levels from very low luminance or even zero luminance to very high luminance levels with good contrast and color rendering. There are many displays that can show high luminance (>1000 cd/m2) and with that are considered or claimed to have daylight or sunlight readability. However, these statements are rarely supported by scientific tests with test subjects. This paper will discuss and analyze the conditions for performing such experiments. Experimental results that the visual acuity is negatively affected by strong illuminance are presented.

Published: July 2014

AbstractThe paper proposes a new concept to drive the display pixel by modulating the pulse width of data voltage to control the discharge through a resistor of the pixel voltage. Thus, the D/A converters, output buffers, as well as the reference voltages in the conventional data driver can be omitted. Without those circuits, the power and cost of the active matrix display can be further reduced.
