AbstractCholesteric liquid‐crystal display (Ch‐LCD) has the bi‐stable characteristic to achieve the energy‐saving for the green technology. Backlight is even unnecessary in the Ch‐LCD system. The single‐inductor bipolar‐output (SIBO) converter is one of best candidate to supply the power management function for the Ch‐LCD with dual positive and negative output voltages by using a single inductor for a compact solution. The energy control methodology with the current‐mode control and the power conservation mechanism (PCM) can strengthen the voltage quality to get high display quality. The test chip fabricated by 0.25 μm CMOS technology demonstrates the non‐noticeable cross‐regulation at dual outputs with 90 % peak power conversion efficiency.

AbstractThis paper presents a high integrated dual‐side dual‐output (DSDO) switched‐capacitor (SC) regulator with only two flying capacitors. Generally, a dual‐phase voltage doubler and an inverter are used to supply positive and negative voltage for TFT‐LCD gate drivers, respectively. Four flying capacitors, eight pin‐outs, and sixteen power switches are necessary for their operations in the driver integrated chip (IC). The proposed DSDO SC regulator combines both dual‐phase voltage doubler and inverter converter into one channel through the use of time multiplexing technique at the cost of little performance degradation. As a result, it not only diminishes the number of flying capacitor from four to two but also removes four IC pin‐outs for low cost and compact size. Beside, sixteen necessary power switches are reduced to twelve for decreasing about 27% silicon area.

Authors: Oh Eunsuk , Song Min Sup , Kang Bongkoo , Park Yong Kyu 
Published: July 2011

AbstractThis paper proposes a direct‐linked Zeta (DLZ) converter as a highly efficient step‐up and step‐down converter. It consists of the conventional Zeta converter components plus auxiliary diode and switch which form an additional power path which directly delivers input power to output load. The DLZ converter can directly deliver much of the input power to the output with little switching and conduction losses, and reduce circulating current in circuit components, thereby reducing switching losses and conduction losses of switches and diodes, winding resistive losses of inductors. The power delivery efficiency of the DLZ converter (96.1%) is 4.4% greater than that of the conventional Zeta converter (91.7%). This result demonstrates that the proposed DLZ converter can be used for highly efficient step‐up and step‐down converters.
12.1: Invited Paper: Image Source Evaluation and Selection for Rugged Near‐Eye Displays
Authors: Melzer James E. 
Published: July 2011

AbstractThere are many high‐quality image source technologies to choose from when designing a near‐eye or head‐mounted display and they can provide excellent imagery. However, when you impose requirements for this same performance under extreme conditions of temperature, shock, and direct sunlight exposure — conditions which might be experienced by military personnel or first responders, the number of options gets smaller. This paper will address the impact of imposing these very stringent environmental conditions on choices for image sources.

AbstractOne‐step cost effective process of fabrication of a full inorganic nanostructured transparent conductive electrode and LC alignment layer has been developed. More specifically, the subject comprises a self‐organized nanomesh of a valve metal, concomitant porous oxide layer with various functionality and electrochemical method of their fabrication. The nanomesh film is electrically conductive, optically transparent and flexible. It can be fabricated on a variety of substrates, including flexible and rigid substrates. High effective LC alignment layers based of nanostructured alumina can be fabricated at the same anodization process by special electro‐chemical technique in sulfuric and oxalic acids to form a self ordered nanoporous structure of alumina which has a “vertical” surface area that prevails over the “horizontal” one even though Al film's thickness is small. The possibility to control distances between pores and their sizes during the process of anodizing/etching enables to optimize alignment surface according to the required LC material.

Published: July 2011

AbstractRecently, as the light‐emitting diodes (LEDs) technology has improved, especially LED brightness is remarkable increased, the brightness of LCD panel is enough even if LED sources are located in only short edge sides (left and right) of the LCD module. As a result, the smart local dimming system is needed to use the invented LED back light unit (BLU) efficiently. In this paper, we proposed the new local dimming system to reduce power consumption and enhance motion picture quality for a new edge LED BLU. The proposed system is applied to active 2D local dimming algorithm and scanning technique at the same time. Our local dimming system has 3 advantages, 25% power saving, 1:100,000 contrast ratio and average MPRT 3.9ms with 240Hz panel. We verified performances by measurement. Finally, our 2D dimming technique was developed as AISC IP type which was merged in timing controller (TCON), so we can apply our system for mass product in 2011 year.

P‐207L: Late‐News Poster: White Light Polarized LED Module for LCD Backlighting
Authors: Chung Chi‐Jui , Lin Po‐Chun , Chen Cheng‐Huan , Yang Han‐Ping 
Published: July 2011

AbstractThe polarization efficiency loss in the pre‐polarizer has long been a major concern in LCD backlighting. Complying the trend of employing solid state light source, this paper presents a polarization conversion module encapsulated on a white light LED for increasing the degree of polarization at the outlet of the whole packaged LED module, so as to improve the overall energy efficiency of direct‐type LED backlighting. The polarization conversion module features a butterfly shape with a wire grid reflective polarizer for separating two orthogonal polarization modes. Due to most of light being incident on the WGP at large angle between 30 and 70 degree, the structure of WGP has been optimized for this range of incident angle, where it is found that dielectric‐metal multilayer nanostructure performs superior to the single metal layer structure. With the consideration on the viability of fabrication process, the module with a WGP featuring cross layered dielectric‐metal nanostructure has been proposed, fabricated and evaluated. The overall photopic polarization efficiency becomes 72%, and the overall efficiency gain is 1.4X.

Published: July 2011

AbstractThe field emission properties of single walled carbon nanotubes (SWCNTs) on organic polymer substrate were investigated. SWCNTs films were first deposited on silicon substrates using spray‐method. In this case.Electrical properties of SWCNTs can be enhanced by acidic and thermal treatments. And SWCNTs films on silicon substrate were transfer onto the PDMS substrate. In this case, in order to improve the adhesion of the SWCNT emitters, transfer process were carried out just before hardening of the PDMS. The viscosity of PDMS grabs the SWCNTs before hardening. From these emitter surfaces, the SWCNT can be turned on with afield as low as 0.9V/μm. An emission current density of 0.75mA/cm2 at 1.2V/μm can be attained. The result establishes a method of fabricating a flexible field emitter, which should find practical applications in vacuum electronic devices.
