TV Technology-RGB LED backlit LCD

5 months ago my boyfriend, ask me to go with him to the sony outlet store in wrentham where he had been told all the QUALIA products where going to be send. He got this TV for only $1700, when it had been originally gone out at $10,000.

Sony had created this line using the latest technology available regardless of price. But obviously, not many where sold and the line did not last more than 2 years.

Product:
Qualia 005
46" LCD television
Unveiled in August 2004
Retail Price: US$10,000


"Qualia was a boutique brand of high-end electronics, created by Sony to showcase their best technology. The line was launched in Japan in June 2003 and the U.S. in April 2004. In 2005, Sony discontinued the Qualia series except in the United States. In early 2006, Sony discontinued the series in the US as well" source: wikipedia





This TV has the Sony’s proprietary TRILUMINOS™ technology, that makes it the world’s first RGB LED backlit LCD television.





Until now, High Definition LCD televisions have been lit by CCFL (Cold Cathode Fluorescent) systems. The technology starts with a white light and uses filters to create onscreen color. The limited color range inherent in the process has always existed as an assumed theoretical ceiling, due to the cost and complexity of other considered solutions. Ignoring these artificial boundaries, the TRILUMINOS LED backlight system takes a completely new approach. Instead of using filters, the LCD panel is lit by individual red, green and blue LEDs. The color control takes a quantum leap beyond today’s most advanced flat panel televisions. Applied to the 46" LCD screen, the resulting realism is breathtaking.

"However, prices for this technology have come far down, allowing Samsung to ship this first TV using the LEDs for $3000. Those in the know say most LCD monitors will be backlit with LEDs by 2010" – Charlie White
