The crystal structures of methyl bromide and methyl iodide have been determined by the X-ray diffraction method at about −120°C and about −80°C respectively. Both the crystals are isomorphous, with orthorhombic space group D2h16–Pnma. Unit cells containing four molecules have the dimensions: a=4.474(1), b=6.420(2), and c=9.150(1) Å for methyl bromide, and: a=4.597(2), b=6.987(1), and c=10.117(1) Å for methyl iodide. These structures are quite different from that of methyl chloride, which has a symmetry of C2v12–Cmc21. In the three crystals, all the molecules are found on the mirror planes; the difference lies in the mutual orientations of the molecules.
We have developed the novel color filter structure suitable for our transflective 'Advanced TFT-LCD'. In this paper, characteristics of the CF and display performance of improved 'Advanced TFT-LCD' with high display-quality are discussed.
Advanced-Super-View (ASV) technology is proposed to achieve high performance TFT-LCDs, in this paper.The ASV-LCDs have high performance characteristics such as high contrast, high brightness, wide-viewing angle, and fast response. The ASV is very promising technology for applications of Audio-Visual Computing.
inch HDTV panel has been developed on the CORNINNG 1737 glass substrate using low temperature CG Silicon (Continuous Grain Silicon). This time we have fabricated TFTs using CG Silicon which uses crystallization with metal catalyst (Ni) and the process to remove this catalyst from channel regions by gettering below 550[ o C].
This paper describes a new concept for low power consumption TFT-LCDs, based on monolithic multi-drivers. The multi-driver architecture consists of two data line drivers, one analogue, one binary, that can operate in tandem or independently. The analogue driver allows the display to show high quality full colour video images. The binary driver provides 8 colour text data display, either on its own, or superimposed onto the image provided by the analogue driver. Operation of the binary driver consumes 1/10 th of the power that operation of the analogue driver needs. The display module can therefore operate at substantially lower power for many display applications, yet still achieve high display performance when demanded.
We have developed advanced Axially Symmetric Aligned Microcell Mode using negative dielectric liquid crystal (N-type ASM mode) first in the world. Using compe nsation film for this N-type ASM mode cell realizes the wide viewing angle of ± ±80°° in all azimuths, and high contrast ratio of 300:1. The structure of this N-type ASM mode panel is suitable for large-sized display panels. This mode is applicable for such active display panels as TFT and PALC 1) display , regardless of the difference of their drive systems. We consider that this N-type ASM mode becomes(N-type ASM mode) a key technology for the next-generation monitors.1.
This paper describes an advanced digital display that we have developed for future mobile applications. The 2" QVGA LCD display contains multi-format digital drivers integrated with a low-temperature Continuous Grain Silicon TFT process. These drivers automatically configure the display format based on the contents of the image data that is transmitted to the panel. This strategy provides an optimum balance between display performance and power consumption.
HDTV rear 60" projector were fabricated using monolithic TFT-LCD'S with newly developed Continuous Grain Silicon (CGS) film. High speed circuit operation due to excellent TFT characteristics was realized. As a result we obtained LCD images without periodic unevenness using data driver without video signal expansion.
