The eighth generation of LCD

S-LCD, the joint venture between Samsung and Sony, have just announced that its factory of 8th generation for the production of flagstones LCD was going to begin the sending of the first flagstones.

An increase in the basic flagstone
Concretely, this factory will produce flagstones basic (in which the screens will be cut out) larger than in the 7th generation, which makes it possible to produce more screens with a large diagonal (or simply to increase the number of screens per basic flagstone). In practice, a basic flagstone (mother glass) of 7th generation measures 1.870 X 2.200 mm whereas the 8th generation passes to 2.200 X 2.500 Misters the seventh generation is optimized for the screens of 40 inches and less, whereas the eighth is especially planned for the flagstones of 50 inches. S-LCD hopes to produce 50.000 flagstones per month by the end of the year 2007.

An increase in the size of the screens
Even if screens LCD of our PC do not use the same flagstones exactly that televisions, the evolutions are generally joint. One can thus suppose that the flagstones of 24 inches will decrease by price, and replace rather quickly the flagstones of 22 inches. Moreover, the very large screens (27 and 30 inches) should also benefit from the increased outputs. Let us note that the shape of the basic flagstones of 8th generation is adapted to the broad screens than the 7th generation

Sharp preps 8th generation LCD fab

TOKYO - In the latest example of display suppliers leapfrogging one another to build larger liquid crystal display (LCD) panels, Sharp Corp. of Japan apparently plans to build an 8th generation LCD fab.

Sharp will use its Kameyama plant to produce 8th generation substrates, which at 2200 x 2400 mm in size are suited to 45- to 50-inch LCD TV panels. That eclipses the 1870- x 2200-mm panels possible with the 7th generation line of S-LCD Corp., the joint venture between Samsung Electronics and Sony Corp. located in Tangjung, South Korea.

When Sharp decided in 2001 to replace all its CRT TVs with LCD versions by this year, LCD TV screens were 13 to 20 inches diagonally. When Sharp launched its first 6th generation fab at Kameyama a year ago, the company introduced a 45-inch LCD TV that generated more orders than expected.

Last October, Sharp demonstrated a 65-inch LCD TV, using its 6th generation fab to cut two panels from a single 1500- x 1800-mm glass substrate.

Sharp plans to build the new fab in a vacant part of the Kameyama plant and will release details on next week (Jan. 12) when Sharp president Katsuhiko Machida presents the company's business plan for the year.

To produce the 8th generation substrates, Sharp will rely on LCD steppers built by Nikon Corp., which has been playing leapfrog with rival Canon Corp. to produce next-generation LCD steppers. Nikon plans to begin volume production of the 8th generation stepper in the fall, eclipsing Canon's 7th generation stepper.

Sharp is considered by analysts the leading supplier of LCD TVs. Since January 2001, the company has produced over 5 million units, accounting for just under half the 10.5 million units produced globally, according to the Japan Electronics and Information Technology Industries Association.
