Authors: Nirengi Takayoshi , Umeya Masanori , Morizumi Daigo 
Published: October 2012

AbstractProducts using rolled flexible glass substrates have been considered difficult to realize due to their brittleness even though they have advantages such as low coefficient of thermal expansion (CTE), high barrier property and thermal and dimensional stability. However, we have successfully developed color filters on flexible rolled glass substrates using roll‐to‐roll processing. One example of the color filter on a roll substrate is 15m in length, and 300mm in width, with a resolution of more than 228 ppi.

39.2: Fully Integration of Transflective Hybrid Device Consisting of PDLC, OLED and OPV
Authors: Chang Wei‐Fu , Wu Cheng‐Che , Chiu Tien‐Lung , Lee Jiun‐Haw 
Published: October 2012

AbstractIn this paper, fully vertical integration of a hybrid transflective device consisting of a PDLC and an OLED with OPV, encapsulated by two glass substrates, were demonstrated. These three devices can be functioned by applying the driving voltage or illuminant, individually. Self‐assembled monolayer (SAM) and passivation layer are dominant factors of this hybrid device. SAM played as a key role to tandem the OPV and TOLED by raising the work function. Passivation also used to prevent the OPV and TOLED from liquid crystal penetration. In this hybrid device, PDLC and TOLED offer a good contrast ratio (CR) in ambient and dark, respectively. The OPV serves to enhance the ambient CR due to the absorptive black background behind this hybrid device. In addition, the OPV also acts as a power generator and recycler to achieve the power saving.

Published: October 2012

AbstractWe developed a dual mode reflective cholesteric display which works in the traditional bistable mode as well as in a monostable mode. In the bistable mode, it is operated between the reflecting planar state and non‐reflecting focal conic state, both of which are stable at zero voltage. The bistable mode is suitable to display static images. In the monostable mode, it is operated on all the intermediate states between the planar and focal conic states. It is fast and has low driving voltage, and can exhibit gray levels of reflectance determined by the applied voltage. The monostable mode is suitable to display video rate dynamic images.

Published: October 2012

AbstractA 720‐channel, 8‐bit source driver has been developed for high resolution and high refresh‐rate applications. A source synchronous point‐to‐point interface has been adopted. The timing relationship between the received clock and the received data is calibrated and configured in the timing controller (TCON).

AbstractThe paper‐like cholesteric liquid crystal display (Ch‐LCD) has become the next generation of electronic readers in consuming market. The embedded fully symmetric self‐biased switched‐capacitor (FSSBSC) with single‐inductor high voltage bipolar‐output (SIHBO) converter is proposed to achieve the energy and area‐efficient driving scheme. As the compact power management module, SIHBO converter can provide +/−35V bipolar outputs for row driving. In addition, the embedded FSSBSC is utilized to generate the different voltage levels for modulating the gray‐color in column driving scheme. This combination carries out the effective driving operation for Ch‐LCD through the demand of timing control unit. Simulated results show the achievement of +/‐35V output voltage in the SIHBO converter and the variety voltage levels generated from FSSBSC. The peak efficiency is derived of 85% with the integrated chip area of 6.53 mm2.

Published: October 2012

AbstractThis experiment created a mobile 2D/3D switchable laser projection system which uses a 2D MEMS scanner. This system can display a two‐dimensional (2D) or a three‐dimensional (3D) image in only one optical engine. In particular, we propose the use of a mobile Color Separation 3D laser projection system that uses different wavelengths of laser diodes. This projection system can display the left and right stereoscopic images simultaneously in one optical engine without using other components such as an alternate color wheel. In this study, the 0.35% and 0.53% crosstalk for left and right has been achieved by separating the wavelengths using filter glasses in a laser projection system consisting of a 2D MEMS scanner and two sets of Red, Green and Blue laser diodes.
48.1: Invited Paper: Panel Self‐Refresh Technology: Decoupling Image Update from LCD Panel Refresh in Mobile Computing Systems
Authors: Kwa Seh , Hayek George R. , Shah Kamal R. , Bhowmik Achintya K. 
Published: October 2012

AbstractMobile computing and communication devices have become indispensable parts of our lives, with rapidly increasing worldwide adoption of laptops, tablets and smartphones. The ever‐increasing demand for both performance and power efficiency of these devices requires a careful look at optimizing the system architecture. For example, image update from the host processor to the display in these devices is still following the traditional CRT approach, with timing and frame rate tracking the panel refresh frequencies even when the image content is unchanged on the display. In this paper, we present the panel self‐refresh technology that allows decoupling of the image update from LCD panel refresh timing, and show the platform powerperformance optimization opportunities it enables.

Published: October 2012

AbstractNew circuit schemes are needed to integrate display‐driving circuits using oxide TFTs because the oxide TFTs operate only as n‐channel field‐effect transistor and tend to have negative threshold voltages. So we have invented circuits that apply negative gate bias to turn off the TFTs inside themselves. In this paper we report some of these circuits such as scan driver, DC‐DC converter, and level shifter.
49.3: Synthesis of High Quality CdSe Quantum Dots with Tunable Size
Authors: Wang Chun , Qin Feng , Lim Byung Cheon , Yoon Yong Jun , Xu Yubo , Lee Seung Kyu 
Published: October 2012

AbstractA cheaper, greener approach for the synthesis of highly monodisperse and tunable size CdSe semiconductor quantum dots was developed by thermolysis of a mixed solution of CdO and Se in non‐coordinating solvent 1‐octadecene at 240°C. Systematic vary of the precursor molar ratios allowed the particle size (from 2.5 nm to 5.5 nm) to be tuned and the size distribution (full width at half maximum of photoluminescence spectra from 26 nm to 37 nm) to be controlled. The results revealed that initial Cd:Se molar ratios play an important role in controlling both the size and size distribution of the as‐prepared CdSe quantum dots. Moreover, the obtained CdSe quantum dots are all of zinc blende phase. The possible reason was discussed. The reaction has been conducted in relatively low temperature at 210°C in the absence of expensive organic phosphine ligands, such as trioctylphoshine and trioctylphoshine oxide. This approach has great value for both the laboratory research and industrial application in term of “green chemical principles”.

Published: October 2012

AbstractThe ball‐drop impact test is frequently used to evaluate the reliability in handheld display products. The finite element analysis provides a convenient way to show kinds of quantitative index to verify the product quality, but the result shows singularly that might affect the failure criteria in glass strength. The stress value at impacted point is too high, due to singularity, to be true and finds out the effective way to confirm is not an easy task in this kind of experiment. This article figures out another quantitative and suitable approach to redefine the criteria of glass failure. The energy approach could be used as an evaluated method and rupture energy from test should be identified for glass to be judged as failure criteria.

Published: October 2012

AbstractThe CIE standard color matching function is used in the description of color characteristics for stimuli reproduced on displays given that these represent visual sensitivity accurately. If this is not the case, the consequent estimation using the functions would be deviated from what we perceive. This study demonstrates the significant errors caused by applying the current standard color matching function for predicting visual results of color stimuli displayed on an LCD monitor equipped with RGB‐LED backlights. The modified version of the standard color matching function is also introduced with its verification results in the reduction of prediction errors.

Published: October 2012

AbstractIn this work, we demonstrate an ultra‐flexible a‐IGZO TFT on PEN plastic substrate. The a‐IGZO TFT could be operated well with almost unchanged performance after banding at radius of 4 mm (strain∼1.5%) for more than 100 times. This was implemented the utilization of polymer gate dielectric, poly(4‐vinylpheonol) (PVP). The PVP was then demonstrated with no damage after plasma process equivalent the the a‐IGZO deposition process. Due to the large Young's modulus difference, the stress was believed mainly within polymer gate dielectric. Therefore, after bending, the a‐IGZO was not damaged. In addition to the ultra‐flexibility, the a‐IGZO TFT exhibit mobility around 1.3 cm2/Vs with nearly 6 orders of magnitude current on/off ratio at operation of 10V. The mobility could be further increase by fine‐tuning the a‐IGZO deposition condition. Combing the ultra‐flexibility and the acceptable performance, this technology is suitable to integrate into LCD or OLED implementing ultraflexible display.
