LEDs move from supporting role to defining advantage at SID2007
LCD screens with LED backlights were shown on almost every exhibit stand at the recent SID 2007 show, indicating that LED technology has a clear future in this market, writes Stewart Hough.
By far the dominant focus of technology and business development in the display industry in the last few years has been large-screen flat-panel televisions, divided into two camps; plasma and LCD.
These technologies have been battling for big screen market dominance for the last 5 years, as well as for bragging rights for who has the largest display. The prize this year went to Sharp Corporation, displaying a full-HDTV-compatible 108-inch diagonal Aquos brand LCD display surpassing last year’s 103-inch plasma display from Samsung.
SID 2007 demonstrated definitively that LCDs from notebook sizes of 10.4-inch to super large TVs over 70-inch diagonal will quickly convert to LED backlights, replacing the gas-filled cold cathode fluorescent (CCFL) tubes that have been the primary light source for LCDs for over 20 years.
