LED backlight units are just beginning to appear in large-size commercial LCD panels, says Brian Bae of Displaybank, but the penetration rate will increase dramatically in the next few years. ![]()
The LEDs are not self-emissive but require an independent light source in the form of a backlight unit (BLU). In medium and large size display segments. However, price wars in the display market and resultant cost reductions have emerged as the crucial problem for LED-based BLUs. Despite numerous advantages, LED-based BLUs have not been widely adopted in larger LCD panels, And need to reach attractive cost levels.
The graph shows that overall BLU market for large-sized LCDs (10-inch diagonal and larger) including applications such as LCD TVs, LCD monitors and notebook PCs. The total BLU market in these applications will increase from 337 million units in 2007 to 481 Millions units in 2010. Penetration of LEDs in the BLU market will increase rapidly from 1.5% in 2007, equivalent to 5.1 million units, to 14% in 2010, equivalent to 67.8 million units.
Considering that only about 1% of large-size products (10-inch and larger) have LED-based BLUs as of March 2007, we foresee a tremendous growth through 2010. Even on the assumption that OLED displays become available with larger designs, LED BLU technology is predicted to continue to take the lead before this happens.
