AbstractThe field emission backlight unit (FEBLU) for liquid crystal display (LCD) panel was fabricated in this work. In order to avoid the space charge on the side of the spacer, the spacer is coated with the TiO2 which acts as the charge leakage layer. By introducing of the TiO2 coated spacers, the assembly of the FEBLU becomes very easy. We have developed the stable 7 inch FEBLU LCD panel which has no discharged breakdown. The FEBLU can be turn‐on at (E0)= 1.26 V/μm, working at 2.64 kV applied field.

P‐114: Achromatic Dark State of MVA‐LCDs with a Negative C‐Plate and a Biaxial Film
Authors: Jiao Meizi , Ge Zhibing , Wu Shin‐Tson 
Published: August 2010

AbstractWe propose a new approach to achieve achromatic dark state of MVA‐LCDs using a negative C‐plate and a biaxial film. In comparison to conventional approach which uses a negative C‐plate and a positive A‐plate, our design shows that the maximum light leakage over entire viewing cone is reduced by ∼6X at 450 nm and ∼4X at 650 nm. The achromatic dark state is essential for improving the contrast ratio, viewing angle and color saturation of MVA LCDs.

Authors: Shin Hun Ki , Seo Joo‐Hong , Yoon Tae‐Hoon , Kim Jae Chang 
Published: August 2010

AbstractWe mixed Alq3 in negative dielectric anisotropy liquid crystal to improve the electro‐optical characteristics of vertical alignment cell. The fabricated vertical alignment cell shows lower operating voltage and faster dynamic response time than pure vertical alignment cell without decrease of the transmittance. We analyzed the physical characteristics of Alq3‐doped liquid crystal in terms of elastic constant and rotational viscosity. Consequently, the fast dynamic response time is caused due to the increase of the elastic constant in the Alq3‐doped liquid crystal cell.

Published: August 2010

AbstractOptical interference (weak microcavity) effects are used to measure the location and width of the emission zone in mixed‐host phosphorescent organic light‐emitting diodes. The consequences of varying composition and varying current density are evaluated quantitatively for the width of the emission zone, the internal quantum efficiency, and the outcoupling efficiency. The devices that are used here are optimized for optical interference effects. The conclusions should carry over to devices that are optimized for practical performance.

Published: August 2010

AbstractThe concept of light recycling has been misunderstood by many who work in the industry as they believe it would violate the brightness principle. This paper first tries to dispel that myth by providing an intuitive interpretation of the brightness principle and hence showing that light recycling is not a violation of this principle. It then goes on to present some general design guidelines as to how and if light recycling can be used in a particular system to enhance its throughput. A highly efficient (with near 100% recycling efficiency) light recycling system and some experimental results are also presented at the end.

Authors: Collomb‐Patton Véronique , Boher Pierre , Leroux Thierry 
Published: August 2010

AbstractViewing angle properties are certainly among the most common characteristics measured on any type of displays and in particular on LCDs. Historically, goniometers have first been used for this task. In 1993 ELDIM has introduced Fourier optics instruments (conoscopes) that are now widely used by many display makers. More recently an imaging technique based on the use of a low reflectance hemisphere has been introduced. All these approaches have their inner advantages and drawbacks depending on the optical setup and the measurements constraints. We present a comparison of these three systems based on their theoretical specifications.

Published: August 2010

AbstractWe proposed the “180Hz Stencil‐FSC” method to suppress color break‐up (CBU) infield‐sequential‐color (FSC) LCDs. Applying local color‐backlight‐dimming technology to FSC‐ LCDs, a “green‐based multi‐color” field‐image was generated to show most image luminance at the first field and effectively suppressed CBU even compared to field‐rate increasing methods. In addition, for further hardware implementation, the number of backlight divisions of 32 ×24 was optimized while considering CBU suppression and image fidelity.

Published: August 2010

AbstractIt is commonly observed that the LED projectors can provide with more perceived brightness by less stimulus luminance. In this work, the Helmholtz‐Kohlrausch effect is applied for studying the enhanced perceived brightness of the LED projector. According to the equations developed by Nayatani's group, the ratio of the enhanced perceived brightness of LED projector is evaluated as 25% to 30% as compared to traditional lamp projector in dark environment. However, in the normal office illumination level, the difference between the LED projector and the lamp projector diminishes.

AbstractWe have fabricated the transparent bottom gate TFTs using Al and Sn‐doped zinc indium oxide (AT‐ZIO) as an active layer. The AT‐ZIO active layer was deposited by RF magnetron sputtering at room temperature, and AT‐ZIO TFT showed a field effect mobility of 15.6 cm2/Vs even before annealing. The mobility increased with increasing In2O3 content and post‐annealing temperature. The AT‐ZIO TFT exhibited afield effect mobility of 33 cm2/Vs, a sub‐threshold swing of 0.08 V/dec, and an on/off current ratio of more than 109 after Al2O3 passivation and post‐annealing. We have fabricated AMOLED panels with the bottom gate AT‐ZIO TFT back‐plane successfully.

It was confirmed by simulation that these host materials have great potential to reduce power consumption of full‐color OLED displays. We also studied hybrid white OLEDs with combining the latest blue fluorescent material and the phosphorescent materials. High luminous efficacy of about 30 lm/W and long lifetime over 200,000 hrs at an initial luminance of 1,000 cd/m2 without any light outcoupling structure were successfully obtained.

Authors: Kwon Jang Hyuk , Jeon Woo Sik , Park Tae Jin 
Published: August 2010

AbstractUsing a narrow band‐gap fluorescent host material with a phosphorescent red dopant, highly efficient red phosphorescent OLEDs (PHOLEDs) exhibiting an ideal external quantum efficiency with a doping concentration of 1% were developed. The origin of such a low doping is revealed by the ideal Dexter doping condition study for efficient energy transfer in PHOLEDs. Besides this cause, the strong fluorescent host materials function very well in phosphorescent OLEDs. Singlet excitons generated by fluorescent host materials in phosphorescent OLEDs can produce dopant triplet excitons via the efficient Förster energy transfer mechanism.

Published: August 2010

AbstractIn the process to build up the complicated system for a LCD backlight unit, a panel and their module assembly, the use of physical prototype has many drawbacks in terms of cost and lead‐time. The virtual prototyping platform, EzOptics we developed in the cooperative work, provides the way of working where the LCD design and optical analysis activities can be developed in the early product development stages. The work being described here permits that a designer analyses the optical characteristics of a LCD module with a panel. In the LCD industry this must be the first system by which the virtual prototyping of LCD can substitute the physical prototype. The system allows a virtual prototype with a full size scale LCD backlight unit and panel modelling without any limitations of the size and shape. The result of the simulation also guarantees the accuracy by supporting the bidirectional scattering distribution functions (BSDF) to define the scattered light propagation over the optical components, and the expert knowledge is provided for more comprehensive, quick and user‐friendly virtual prototype modelling.

Published: August 2010

AbstractA buffer amplifier for 10‐bit digital‐to‐analog converter (DAC) with embodied 4‐bit interpolation is proposed for AMLCD column drivers. Under the proposed interpolating scheme, the reference voltage from 6‐bit DAC is interpolated with the voltage generated from 4 bit directly inputted codes in the buffer amplifier. This proposed circuit can reduce the effective size of the DACs, and achieve the accurate channel output maintaining the basic function of the buffer amplifier. The average static current of the proposed buffer amplifier is 1.2μA per each channel and the simulated result of INL and DNL by 0.35μm CMOS process is less than 0.06 and 0.05 LSB.

AbstractAutostereoscopic 3‐D displays enable immersive experiences in entertainment and media consumption. 3‐D movies serve as an example of this and especially in mobile environment the concept of 3‐D short movies may offer the user new means of filling micro breaks. Since movie production is international, subtitles are essential in some cases to allow wider distribution of the movies. with 3‐D movies the way the subtitles are shown, an understanding of the consequences of the depth levels used either in the content or the subtitles is crucial. This paper describes the results of subjective tests investigating subtitles in stereoscopic 3‐D still images for small size displays. More precisely the effect of different depth levels of the subtitles and their interaction with different scene contents with varying depth has been investigated.

AbstractA hybrid silicon technology (HyST) thin film transistor (TFT) process using a diode‐pumped solid state (DPSS) laser has been developed by implementing low‐temperature poly‐Si (LTPS) TFTs with a‐Si:H TFTs on the same substrate. HyST TFTs are deployed on the peripheral area of a panel for integrated gate driver circuits and a‐Si:H TFTs are used as switching devices for pixels in the active display area. This technology is based on the current a‐Si:H TFT fabrication processes without additional ion‐doping and activation processes. Field effect mobilities of 4 ∼ 5 cm2/V⋅s and 0.5 cm2/V⋅s for HyST and a‐Si:H TFTs, respectively, are obtained. Low power consumption, high speed, small integration area, high reliability, and low photosensitivity are achieved by means of HyST TFTs, compared to gate driving circuits integrated with a‐Si:H TFTs. A 14.1‐inch WXGA+ (1440×900) LCD panel has been demonstrated using the new HyST TFT process.

AbstractThis paper presents a methodology for including the photometric raw data sets into the diffuse illumination in display system. The method is based on computing the luminance distribution on the outgoing side of diffusing elements from measured bidirectional scattering distribution functions (BSDFs). The calculation procedure includes the linear superposition and the feedback. As an application example, the method is verified by a commercially available diffusing sheet illuminated by a 32‐inch backlighting module. Close agreement (correlation coefficient = 98.6%) with the experimental measurement confirmed the validity of the proposed procedure.
