Television viewing has changed greatly with the rapid evolution of TV-related hardware. In the 70's, home video spread quickly, in the 80's, remote controls became common, and in the 90's, flat-screen televisions entered the market and large-screen televisions became practically commonplace. The living room was transforming into a home theatre. Expanding screen sizes had led to development of a dream television for the next generation.

Development of Hi-Vision Television

Research on Hi-Vision had already begun near the time of the Tokyo Olympics. Around 1971, STRL began to research thin, large-screen televisions suitable for Hi-Vision. Researchers studied various technologies including LCD, EL, and LED, and decided to proceed research on plasma display panel, or PDP, after determining that they represented the fastest route to thin, large-screen televisions. First, three phosphors for the primary colors, red, green and blue, plus suitable filler gases, were developed in order to produce a color display. At the time, prototype PDPs were very dim, so various techniques were developed, such as using the memory drive to increase the length of luminance. Improvements were made to the PDP structure in order to achieve practical levels of luminance.

STRL led the way in the development of large-size PDP manufacturing equipment, and developed the world's first 40-inch color PDP. STRL also joined the Association of Research and Development of Hi-Vision PDPs, and has contributed greatly to the development of practical, large-screen PDPs.


The Spread of Thin-Screen TV

When thin-screen televisions were first being developed, making them larger presented serious technical problems, but the rapid technological progress of peripheral industries such as glass substrates and equipment manufacture, in combination with vast improvements in operating performance, have resulted in successful construction of TVs over 100 inches in diagonal. Liquid crystal displays, developed in the 70's for calculators, improved certain problems with operating speed and viewing angle, and along with PDPs, rapidly gained popularity throughout households. As thin-screen televisions increased, so did large-screen viewing, and this created an environment where people could get the maximum benefit out of Hi-Vision TV. The move to large screen televisions, together with the spread of video recording media (DVD, etc.), also increased the popularity of home theatres; viewers could enjoy high-quality movies and videos in the comfort of their own homes.


The Dream Television

The pursuit of a Hi-Vision flat-panel television that delivers an even more heightened realness continues with Super Hi-Vision television, which will provide an even higher sensation of realness.
Researchers also continue to work towards achieving the dream of a wall-mounted unit for an entire wall, with all equipment hidden behind the display so that only the screen is visible.
