Cree Inc has announced that it has significantly increased the brightness of its blue and green LED
chip products targeted for the design of energy saving LED backlighting solutions for larger LCD
monitors and TVs.
For high power LED-based backlight systems, Cree is now shipping blue XB900 power LED chips that
are 38% brighter, increasing the minimum radiant flux from 65mW to 90mW, and green XB900 chips
that are 33% brighter, increasing the minimum radiant flux from 30mW to 40mW. For backlight
systems using smaller chips, Cree has increased the brightness of its green XThin LED chips from
8mW to 10mW, for the top radiant flux bins, to better match the high brightness of the company's blue
XT-21 and XT-24 chips.
Cree's brighter chips mean less power is needed to meet the brightness specifications for backlighting
applications, reducing energy consumption and the need for active cooling systems.
