Projection Display Series for High-Definition TV

Abstract

High-definition TV is an expected next generation television broadcasting system, and the broadcast of which will start in 1990 in Japan. The system is also expected for the use of industrial application. For these requirement , 54 -inch, 110 -inch, and 200 -inch projection displays have been developed. The horizontal resolution of 1000 TV lines, the peak brightness of 410 cd /m2 (54-inch), and the contrast ratio of more than 100 for rear projection displays can be realized by the development of 9 -inch dual focusing projection tube, high resolution projection lens, fine pitch high contrast rear screen and large output horizontal deflection circuit etc..

Prospects for the implementation of magneto-optic elements in optoelectronic integrated circuits: a personal perspective

“…As stated in the introduction, the major focus of research in waveguide magno-optics has been in thin-film iron garnets grown on gadolinium gallium garnet substrates [2,4] which offer relatively large Verdet constants and low optical losses over a wide wavelength range. However, growth of garnets on the semiconductor or silica substrates commonly used in OEIC/PICs has not been possible.…”

“…These normally consist of thin-film iron garnets (e.g. yttrium iron garnet) grown on a gadolinium gallium garnet substrate [2][3][4][5]. The optical and magnetooptical properties can be tailored by substitution (e.g.…”
