Self-scanning LCD process claims to cut costs by 30%
Tom Foremski The Sarnoff Research Center has developed an LCD manufacturing process that it claims cuts costs by almost one third. Called self-scanned amorphous silicon display (SASID), the process cuts manufacturing costs by up to 30 per cent and improves interconnect reliability tenfold. Sarnoff has begun licensing the technology and predicts that it will significantly lower LCD prices which have recently gone up with increasing demand. “The most costly part of a laptop computer is its screen, and the cost of the screen is limited by the expensive TAB interface at the edge,” said Roger Stewart, head of solid state displays at Sarnoff. A key advantage of SASID is that it can be implemented using standard AMLCD production lines. The technology is already being used in Europe and Taiwan, but Japanese LCD makers, who dominate the market, have yet to license it. SASID reduces the number of wiring connections around the edge of the AMLCD screen by up to 95 per cent. The number of connections required for an SVGA (600 x 800) display drops from 3,000 to just 202 using SASID.
