"These are likely to be the integrated digital televisions, whereas at the moment people are using cathode-ray tube
TVs and set top boxes which give off a lot of energy as heat.
This vacuum tube was the precursor of every piece of electronics invented over the next 65 years and is still the basis of the cathode-ray tube
used in TVs and computer monitors.
The cool, distant, passionless light of the cathode-ray tube
now provides our guiding illumination, and a bleak, antiseptic light it is.
In a cathode-ray tube
display, a scanning electron beam causes phosphors to glow at selected spots.
The SED TVs, which they say will provide image quality comparable to that of cathode-ray tube
TVs despite their ultra-thin display panels, will offer ''excellent performance characteristics,'' according to the two.
Overall sales dipped 1.3% to 5,579.51 billion yen thanks to revenue drops of 176 billion yen stemming from the transfer of Toshiba's cathode-ray tube
business and industrial system business to subsidiaries.
The recycling rate came to 60.2% for notebook PCs, whose required rate was 20%, 72.4% for cathode-ray tube
displays against their required rate of 55%, and 74.0% for crystal displays, also against 55%.
However, says Greg Vorhees, "the only material we're truly recycling [in-house] is cathode-ray tube
(CRT) glass" from television picture tubes and the 250,000 computer monitors his company will process this year.
Since cathode-ray tube
monitors tend to provide much higher contrast ratios than LCD or plasma displays, professionals have long used high-end cathode-ray tube
monitors, the company said.
Of the total, sales of liquid crystal TVs stood at 286,000 units, while cathode-ray tube
TVs and plasma panel TVs came to 247,000 and 121,000 units, respectively.
The shutter consists of several polarizing filters and a liquid-crystal cell, which form a sandwich that can be placed in front of a cathode-ray tube
. Electrical signals sent to the liquid-crystal cell rotate the liquid-crystal molecules so that green and red light get through at different times.
But shipments of conventional cathode-ray tube
TVs fell 17.6% to 6.81 million units.
