AbstractA novel high speed integrated gate driver using a‐Si TFT for large size 240Hz FHD TFT‐LCD TVs has been developed. The proposed circuit architecture achieved high speed operation by means of separating control signal from output signal and double buffer. Two channel shared node structure also reduce the area of the circuit without performance degradation, while the life time of the integrated gate driver is estimated to more than 50,000 hours. Thus we successfully developed the true 240Hz FHD TFT‐LCD panel using 1G‐1D driving method with this integrated gate driver

AbstractThis study reported a low temperature polycrystalline silicon LTPS thin film transistor TFT fabrication process on plastic substrates for flexible display applications. Polycrystalline silicon poly‐Si films were formed by excimer laser annealing ELA method. It was found by ELA thermal simulation that there was around 70 □ on plastic surface during ELA crystallization process. The excimer laser irradiated film was analyzed by using various spectroscopic methods such as X‐ray diffraction, scanning electron microscopy, and atomic force microscopy. Dehydrogenation and activation processes were performed by a conventional LTPS method without causing any plastic substrate distortion. The fabricated poly‐Si TFT on a flexible backplane shows a very good performance with field effect mobility of 95.3 cm2/Vs, on/off ratio current ratio > 108, and threshold voltage of −1.6 V. Bending tests after a delamination process were also performed with TFT backplane samples.
19.2: Ambient Environment Reactive Displays
Authors: Yuan Chang 
Published: July 2011

AbstractWe propose a novel feature for flat‐panel displays; that is to allow displays to react to dynamic changes in the ambient environment around the display, especially lighting variations. A real‐time reactive rendering algorithm analyzes the ambient lighting conditions captured by multiple sensors installed on the display and transfers physical lights into on‐screen content. Real‐life action images demonstrate the uniqueness and effectiveness of our approach.

Published: July 2011

AbstractIncreased display efficiency gives device manufacturers more freedom to design new, previously unfeasible, low power devices. By combining an energy efficient backlight design with an efficient light source, display powers can be lowered to levels where a power source other than alternating current AC mains becomes feasible. Examples of a USB powered monitor in the mainstream size, as well as a Power Over Ethernet POE All‐In‐One Thin Client/Monitor device are demonstrated with today's technologies as a combination of efficient LEDs, reflective polarizers and low power LCD panels.

Authors: Wittek Michael , Tanaka Norihiko , Bremer Matthias , Pauluth Detlef , Tarumi Kazuaki , Wu Ming Chou , Song Dong Mee , Lee Seung Eun 
Published: July 2011

AbstractCompared to other liquid crystalline mesophases, the Blue Phase exhibits extremely fast switching via induced birefringence by an external field. However, the pure Blue Phase is characterized by a rather narrow temperature range on the order of a few K. For display applications, one very promising way to broaden the stable temperature range is achieved by polymer‐stabilization of the Blue Phase. A crucial prerequisite for efficient stabilization is the optimal material selection/matching of reactive mesogens RMs and the chiral host. New material concepts will be introduced and discussed.

Authors: Haun Andrew M. , Peli Eli 
Published: July 2011

AbstractWe show how perceived contrast of natural images, as a function of spatial frequency, is measurable using a novel form of the psychophysical ‘classification image’ paradigm. Contrast spatial frequency weighting functions peak at mid‐high frequencies, and are more stable than predicted by common definitions of image contrast or contrast sensitivity.
24.2: Estimating the Perceptual Limits of Mobile Displays
Authors: Zafar Fahad , Choi Mina , Badano Aldo 
Published: July 2011

AbstractThe quality of the displayed image in mobile devices is affected by the varying ambient illumination conditions. Determining appropriate viewing conditions for particular visual tasks requires appropriate instrumentation. However, visual tests can be more practical. We conducted experiments to explore the limitations of mobile displays in terms of the visibility of subtle targets. We explored the effect of background luminance and ambient lighting using two methodologies: a text detection task where the observer identifies characters embedded in noisy backgrounds and a threshold estimation staircase technique. We found that the text detection method holds promise as a surrogate for more complicated tests in the framework of a clinically practical implementation.

We utilize the low Ioff of the oxide semiconductor and make frame rate lower, which leads to the lower power consumption of drivers. The color sequential LCD can have a monochrome electronic paper function with a white backlight on.

35.5L: Late‐News Paper: An Ambipolar Oxide TFT
Authors: Hosono Hideo , Nomura Kenji , Kamiya Toshio 
Published: July 2011

AbstractWe fabricated transparent oxide semiconductor‐based ambipolar TFTs on SiO2/c‐Si with a maximum process temperature of 250 °C. Saturation mobilities of ∼0.81 cm2(Vs)−1 for p‐channel and ∼5×10−4 cm2(Vs)−1 for n‐channel operations were obtained at RT. We demonstrated a complementary‐like inverter comprised of two SnO‐based ambipolar TFTs. The inverter operated with a maximum voltage gain of ∼2.5. This is the first demonstration of an oxide‐based complementary‐like inverter using a single channel material, which allows simple fabrication of complementary logic circuits based on oxide TFTs. In addition, the device operates stably in air, is optically transparent and can be fabricated at 250 °C. Therefore, the essence of our findings can further be extended to flexible substrates. We expect that optimization of processing and more appropriate selection of source/drain electrode materials will improve the n‐channel mobilities, and pave the way for oxide‐based complementary circuit technology.

Published: July 2011

AbstractOxide TFTs have a negative threshold voltage (Vth), which can become even more negative in response to DC or AC stress. Therefore, these voltage stresses can cause severe leakage current in a scan driver. In this paper, a scan driver with dynamic threshold voltage control (DTVC) is proposed to minimize the leakage current and enlarge operating margin. Effectiveness of DTVC was verified with a 14‐inch AMOLED.

Authors: Vang Kalc C. , Yu Ta‐Hua , David Moses 
Published: July 2011

AbstractA new random, anisotropic, nanostructure, contrast enhancement film (NCEF) with super low reflection broadband antireflection (BBAR) performance was developed by 3M Company using a wide web roll‐to‐roll process. The high performance BBAR NCEF film can be made from triacetate cellulose (TAC), polyester, polycarbonate, polymethyl methacrylate, or many other substrates commonly used for electronic display applications. At normal incidence, a TAC based BBAR NCEF exhibits an average reflectivity of 0.1% measured in the visible spectral range 400‐700 nm, and a total light transmission of > 97% is obtainable from single side nanostructured BBAR NCEF. Furthermore, BBAR NCEF film was shown to provide high light transmission at wide incidence angle with minimal optical loss making it well suited for viewing at wide viewing display angle. The roll format combined with the high performance characteristics of this BBAR NCEF film makes it an exceptional cost‐effective solution to be implemented on most electronic display modules.

53.4: Highly Polarized Backlight Consisting of an Aperture‐limited Light Guide Plate and a Hybrid Wire‐Grid Polarizer
Authors: Chung Chi‐Jui , Yao Po‐Hung , Chen Cheng‐Huan 
Published: July 2011

AbstractOn the purpose of improving the transmittance of LCD panels, the study of polarized illumination has been emphasized as one of the urgent topics to reduce the energy loss at the present absorption‐type polarizer of LCD cells. The polarization‐selection property of nano‐wire‐grid structures has been widely studied for a reflective polarizer and applied to increase the transmittance of LCD. For a determined wire‐grid polarizer, the transmittance of P polarization (Tp) depends on wavelength and incident angle. The effective incident angle is limited by total internal reflection (TIR) condition of selected polymer materials for wire‐grid substrates. This paper presents a polarized backlight unit consisting of an aperture‐limited light‐guide plate featured by plurality of aluminum‐coated trapezoid ridges on the output surface and a hybrid nano wire‐grid which has been proposed to improve the transmittance of LCD by polarization recycling and emission angle control. Gain of central brightness was achieved up to 2.1x.
