Using LEDs for backlighting of LCD displays has an advantage compared with CCFLs from the perspective of:
  • environmentally friendly
  • lower power consumption
  • a thinner form-factor
Mobile devices, including smart phones, tablet PCs, GPS devices, as well as larger LCD panel applications such as TVs, PC monitors, notebooks, have already widely adopted LED backlighting systems because of the slim form-factor which has become the trend in consumer electronics. STMicroelectronics’ complete product and solutions portfolio addresses the widest range of circuit topologies and architectures in use today for these applications.
