会議録・要旨集 フリーWe examined the dynamic response of the chiral-homeotropic liquid crystal cell by measuring the optical transmittance. It was found that the well-known optical bounce Phenomenon which was originally found in the twist nematic cells, also appears in the chiral-homeotropic cells. The field induced backflow causes this optical bounce and it may influence the dynamic response of the cell. In this paper, we will present the experimental data and use a simple model based on ELP theory to explain the optical bounce phenomenon appearing in the homeotropic to planar state transition.抄録全体を表示PDF形式でダウンロード (377K) -

会議録・要旨集 フリーThis study aims at driving a liquid crystal medium without using address electrodes or driving circuits ; surface electric charging is used instead. This driving method can yield displays that are more compact and lower in cost. This style of LCD well fits the concept of Digital Paper. We examined the basic display characteristics of a Guest-Host PDLC when the surface electric charge is formed using the ion projection method. Repeated image formation and erasure on PDLC device by ion projection and heating were confirmed. Plain display characteristics that were independent of viewing angle were obtained. These results indicate that Guest-Host type PDLC devices are interesting candidates for realizing the concept of Digital Paper.抄録全体を表示PDF形式でダウンロード (468K) -

会議録・要旨集 フリーTNセルやSTNセルにおける液晶分子のねじれ角を精度良く測定する方法は報告されているものの、配向膜の容易軸の組み合わせ角度を高精度で決定することが困難であり、配向規制力を計算する際の誤差の原因の一つとなっている。この問題を解決するために、我々は軸対象に液晶を配向させた基板と一方向配向基板を組み合わせることにより、容易軸の組み合わせ角度が0°から90°の範囲で連続的に変化するセルを作製した。さらに、この液晶セルにより液晶層の厚みと液晶分子のねじれ角度の2D分布をストークスパラメータ法を用いて測定し、方位角方向の配向規制力について検討したので、それらの結果を報告する。抄録全体を表示PDF形式でダウンロード (466K) -

会議録・要旨集 フリー高精細CRTに発生するラスタモアレを低減するために、ガウス関数重みづけ法を用いて視認されるモアレパターンをシミュレートする技法を開発した。モアレパターンは、ビームプロファイル形状の影響を強く受ける。この技法を用いることで、さまざまなモードに対する最適なビームプロファイルの追求が可能となる。一般にガウス分布はラスタモアレを低減する最適な電子密度分布であると言われているが、本論文で、ガウス分布をわずかに変形させたプロファイルが視認されない程度までモアレコントラストを低減できることが分かった。これにより、ラスタモアレを低減するCRTの電子銃を設計することができる。抄録全体を表示PDF形式でダウンロード (435K) -

会議録・要旨集 フリーStrong demand exists for the development of high-current-density and long-1ife cathodes for use in cathode ray tubes (CRTs). In response to this demand, the authors have developed and implemented the mass production of two types of Ir-coated 411 type dispenser cathodes having a heater power of 1.31 W and 0.76 W, respectively. These cathodes were designed by computer simulation, and have astructure that allows them to be assembled in electron guns configured for conventional oxide cathodes. The following three types of life tests were carried out in order to confirm the reliability of the cathodes : (1) To investigate temperature changes during the life of the cathodes, a life test of approximately 40, 000 h was conducted. The resultant temperature change was small, confirming that the reliability of the cathodes is satisfactory. (2) To investigate emission life, a 32, 000 h life test was conducted. The stability of the emission current was thereby confirmed. (3) To investigate heater life, 39, 000 h life tests were conducted at several heater temperature levels with a voltage of 300 V applied between the heater and the cathode. From the results of these tests, the minimum life of the heater is estimated to be 80, 000 h. The results obtained in the above tests confirm that these cathodes possess good reliability.抄録全体を表示PDF形式でダウンロード (476K) -

会議録・要旨集 フリーWe have developed a 4-domain in-plane switching liquid crystal display (IPS-LCD) with a novel electrode structure, where data electrodes and common electrodes are perpendicular to each other. These two electrodes are formed in different layers isolated by a dielectric thin film, with larger tolerance to error of alignment between these two electrodes than conventional IPS-LCD. When a voltage difference is applied to the electrodes, liquid crystal molecules will re-orient in different directions due to the non-uniform distribution of the electric field. This results in a 4-domain LCD with vanishingly small color-shift for viewing angle over 60 degrees in the horizontal andvertical directions. The overlapping areas of these two electrodes form a part of storage capacitor for TFT-LCD apprication, which help to enlarge the apelture ratio.

会議録・要旨集 フリーSmall elastic constants and large Δ ε LC substances need to develop the low driving voltage LCD. The phenomenological and theoretical calculation can be applied to develop large Δ ε LC substances. It is very important to reduce the ion density of LC cell for good reliability LCD that is characterized with small residual DC and high voltage holding ratio. It has been found that the coexistence of large Δ ε and good reliability are possible by the screening of LC substances. Non-polr substances featuring small γ _1 and low Δn also have been developed, and they can be applied for not only TN but also for IPS and VA modes.抄録全体を表示PDF形式でダウンロード (324K) -

Both alignments can stabilize the planar texture and the focal conic texture of cholesteric liquid crystals. We compared the optical performance of the high-pretilt homogeneous SSCT with that of the homeotropic SSCT and found that the homogeneous SSCT can have more uniform coloration over very wide viewing angles, but with a smaller contrast ratio. The contrast ratios for both SSCT are greater than 5, which can be used in such applications as electronic newspapers and PDA.抄録全体を表示PDF形式でダウンロード (386K) -

会議録・要旨集 フリーA simulation program of CRT design, specially focused on mask design. is proposed in the present study. Incorporating the back-tracing results of exposure system along with three-dimensional spatial geometric relations, the weighted least square method is applied to solve the characteristics of each R-G-B trio in full screen. The nesting arrangement for full screen is obtained by setting a flat mask pattern, included as horizontal/vertical pitches and aperture size. ln the same manner, the landing distribution of electron beam could be found by inputting the magnitude of misregistrations. The improvement of mask design is judged according to the increase in the guard-band of nesting distribution. Graphic User Interface (GUI) is another target in this work. Within GUI environment design engineers can comfortably operate the simulation system to input mentioned design parameters, such as : flat mask pattern, formed mask geometry. q spacing, etc. Also, the simulation results, both R-G-B trio and nesting arrangement, can be shown graphically.抄録全体を表示PDF形式でダウンロード (896K) -

会議録・要旨集 フリーIn order to meet the requirements and expectations from customers, it is necessary to improve continuously the quality of products. For color display tubes, the brightness uniformity is one of main concerns of customers and end users. We are starting a new approach method to improve the brightness uniformity. The causes of influencing the brightness uniformity include exposure correction lens (landing), exposure filter, photographic process, shadow mask design...etc. The design of filter, which corrects the light intensity distribution in the exposure system, is the most important. We can measure 192 points for tubes'brightness distribution and black matrix hole size distribution within a certain time. From the measuring results, a new correcting filter to improve the brightness uniformity can be made by our design model. The sizes of black matrix from the center to the edge are made almost as target. Better brightness uniformity in a color display tube is realized.抄録全体を表示PDF形式でダウンロード (445K) -

会議録・要旨集 フリーIt is known that moire is the counterpart of readability/focus performance. Nowadays, the requirement on the readability of a CDT is getting higher and forces the gun designers to make beam spot smaller and smaller. This makes moire inevitable under certain application conditions, because the visibility or moire pattern is determined by the electron beam spot, while the structure of mask aperture determines moire wavelength. This paper is devoted to study the relationship between the visibility of scan moire and spot size from measurements. The modulation depth (MD) of moire and electron beam spot are measured by a CCD camera. By varying the horizontal Dynamic Astigmatism and Focus (DAF) voltage, the variations of moire MD with beam spot are acquired. It is found that the spot size at both 5% and 50% of luminance distribution can characterize the moire MD in agreement with theoretical calculation.抄録全体を表示PDF形式でダウンロード (264K) -

会議録・要旨集 フリーPECVD is one of the most critical technologies for manufacturing AM LCD devices. Advanced PECVD systems have been developed for low temperature deposition of a-Si, SiNx, SiO_2, SiON, and n+Si films. Typically, cluster tool configurations are used since they provide excellent process control with single substrateprocessing and flexible process flows. Recent reports indicate that good polysilicon TFTs have been manufactured using laser crystallization of a-Si precursor films. This paper will review the development of PECVD systems for volume manufacturing of LCDs and discuss process technology and requirements for future manufacturing.抄録全体を表示PDF形式でダウンロード (399K) -

会議録・要旨集 フリーThis article demonstrates good quality amorphous silicon thin film transistors (TFT) fabricated with a maximum processing temperature of 110 ℃ on glass or flexible transparent plastic substrates, using rf plasma enhanced chemical vapor deposition. Hydrogen diluted silane was used for the preparation of the amorphous silicon (a-Si), while SiH_4/NH_3/N_2 or SiH_4/NH_3/N_2/H_2 mixtures were used for the preparation of silicon nitride (SiNx) films. Gate and source/drain metal was sputter deposited molybdenum. Plastic substrates were indium tin oxide (ITO) coated polyethylene terephthalate (PET). Transistors formed, using same processes, on glass and plastic show linear mobilities of 0.33 and 0.12 cm^2/Vs, respectively, with I_<ON>/I_<OFF> ratios greater than lO^6. For transistors on glass, the achieved highest linear mobility is 0.54 cm^2/Vs. The stability of transistors was characterized using electrical stress measurements. The threshold voltage shift is 5.0 volt for a typical transistor on glass substrate, using a stress condition of Vg=25 volt, 600 seconds. Without applying electrical stresses, threshold voltages and linear mobilities of all transistors were found to increase with storage time. We suggest that the relaxation of the interface (SiNx/a-Si) through the bond breaking of the weakest Si-Si bonds contribute the observation.抄録全体を表示PDF形式でダウンロード (438K) -

会議録・要旨集 フリーA new back channel etched hydrogenated thin film transistor (TFT) device with an island metal masking structure has been proposed and fabricated. The TFT structure contained a continue layer deposition process of SiNx/a-Si/n+a-Si/Metal, and finally resulted in an additional metal layer between source/drain metals and island. The channel metal was etched in the S/D metal mask patterning simultaneously. Results showed the newly designed TFT device exhibiting some characteristics : (i) good S/D metal/n+a-Si contact ; (ii) prevention of plasma damage during processing especially for oxygen plasma ashing and (iii) without additional mask. These advantages will be helpful for a wider range of process window in large area mass production a-Si TFT fabrications.抄録全体を表示PDF形式でダウンロード (311K) -

会議録・要旨集 フリーA p-channel poly-Si CMTFT (Conductivity Modulated Thin-Film Transistor) is demonstrated and experimentally characterized. The transistor uses the concept of conductivity modulation in the offset region to obtain a significant reduction in on-state resistance. This structure can provide 1.5 to 2 orders of magnitude higher on-state current than that of the conventional offset drain TFT at drain voltage ranging from -15V to -5V while still maintaining low leakage current and simplicity in device operation. The p-channel CMTFT can be combined with the n-channel CMTFT to form CMOS high voltage drivers, which is very suitable for use in fully integrated large area electronic applications.抄録全体を表示PDF形式でダウンロード (393K) -

会議録・要旨集 フリーEffect of parasitic resistance (Rp) on the mobility in laser-crystallized low-temperature (LT) poly-Si thin film transistors (TFTs) of various channel lengths was investigated. The minimum off current at Vd=10V in these TFTs is scaleable and is about 0.15 pA/μm. Significant reduction of mobility was observed in short channel devices due to parasitic resistance. Based on our analysis of the Rp requirement for high-performance short-channel LT poly-Si TFTs, to avoid significant degradation in the mobility for the mobility larger than 300 cm^2/Vs, it's necessary to keep Rp below 200 ohm.抄録全体を表示PDF形式でダウンロード (414K) -

会議録・要旨集 フリーWe present optical modeling of small pixels in reflective liquid crystal display (LCD). The optical analysis is divided into two parts. In the first part, the two-dimensional (2D) director configuration of the LCD in rectangular mesh was calculated by simultaneously solving the 2D Poisson equation and a 2D continuum theory equation. In the Second part, the generalized Jones matrix was used to simulate for the optical reflectance through the LCD with the 2D director configuration obtained from the first part. This optical modeling was applied to analyze optical reflectance of small pixels in reflective mixed-mode twisted nematic (MTN) cells on silicon substrate. Both the simulated and experimental data of the MTN cells with a pixel pitch of 10 to 25μm under frame and column inversion of polarities are presented.抄録全体を表示PDF形式でダウンロード (487K) -

会議録・要旨集 フリーWe have developed a highly integrated liquid-crystal-on-silicon microdisplay for virtual reality applications. The silicon panel was designed and fabricated by a custom 0.5μm 3-metal CMOS technology with 704 x 576 pixels. We further utilized field programmable gate array (FPGA) as an application specific integrated circuit to implement a color sequential technique. Image scaling was also applied to linearly expand VGA, NTSC and PAL images in order to fill the whole display panel. As a result, we were able to display VGA, NTSC and PAL videos by the same display system. This compact microdisplay system can lead to a variety of virtual reality applications.抄録全体を表示PDF形式でダウンロード (519K) -

会議録・要旨集 フリーA high performance reflective microdisplay has been developed that is capable of supporting color video operation at resolutions of XGA and above. The device uses ferroelectric liquid crystal and is fabricated over a silicon substrate on to which the reflective metal pixels and device addressing circuitry are fabricated. Both the silicon processing and the assembly of the LC cell use industry standard processes which results in a very high performance and low cost device. These displays are suitable for use in head mount and projection display systems. A particular advantage of the technology is that in enables the design and production of low cost single channel color systems which are predicted to be both cost and performance competitive with existing CRT products.抄録全体を表示PDF形式でダウンロード (394K) -

会議録・要旨集 フリーバックライトを用いない明るい反射型液晶は携帯型情報システムのキーデバイスとなっている。その中でもゲスト・ホスト型液晶表示素子は2色性色素の吸収異方性を用いるため、大変広い視野角を有している。そのため複屈折モードや旋光モードの表示方式で用いなければならない複雑な光学補償が不要となる。白黒表示のGH-LCDはマイクロカラーフィルタ表示の光バルブとして用いることができる。この場合、正確に無彩色を表示しなければならない。従って、色素を混合して無彩色となるように濃度を調整しなけらばならない。Newton-Raphson法は設計した色彩を得る最適濃度の計算に適している。本報告では得られた結果の判定方法について検討している。その結果本法は迅速かつ容易に実現性を評価できることが明らかにされた。この方法により反射型カラーLCDの設計において有用な指針が得られ、LCDの表示品位の向上が図られる。抄録全体を表示PDF形式でダウンロード (341K) -

会議録・要旨集 フリーWe have developed a high quality and simplified multigap color filter (MCF). Amultigap LCD is effective for reduction of color dispersion and improvement of viewing angle. A MCF is achieved by applying a single-layer of transparent positive type photo resist to the multigap color filter. The gap difference is easily determined by controlling amount of the UV exposure. The high degree of flatness of MCF, compared to that obtained by double-layer of transparent negative type photo resist, will be shown. Investigation of the influence of post exposure process on the transmittance will also be reported. The high quality, simplified MCF with only one additional coating of photo resist to color filter is easy to apply to many types of LCD, such as OCB and normally black TN for performance improvement.抄録全体を表示PDF形式でダウンロード (355K) -

会議録・要旨集 フリーThe narrow viewing angle of the twisted nematic liquid crystal displays (TN LCDs) limits the display's performance especially on the desktop monitors or large size TVs. Recently, the compensation films have been extensively developed to improve the viewing angle of TN LCDs. We have investigated the compensation films for TN-LCDs which are combined O-plates and C-plates, The parameters of the compensation films have been optimized by computer simulation and these results showed that the films could minimize the oblique leakage light of the dark state and improve the viewing angle efficiently.抄録全体を表示PDF形式でダウンロード (348K) -

会議録・要旨集 フリーPolyimide was applied to aligning liquid crystals (LCs) since 1970. It is desirable that polyimide perform stable conformation to control the pretilt angle of LCs. Low pretilt angle (1-2 degrees) of LCs is the key issue for high duty TN-LCD. In this paper we report the design, synthesis and properties of a series of polyimide alignment materials for LCs. The LC cells exhibit stable pretilt angle (less than 2 degrees) irrespective of curing temperature and rubbing treatment, also show no reverse tilt disclination after thermal annealing treatment. We suggest that rigid biphenyl skeletons are the key factor for the stable conformation of polyimide alignment materials.抄録全体を表示PDF形式でダウンロード (259K) -
