As Samsung has demonstrated with its early moves into bright AMOLED touchscreens, the display technology is becoming a key differentiator in handsets. Now LG is promising a new breakthrough, offering more colors and lower power consumption using a technology called 'quantum dots'.
LG Innotek, part of the Korean conglomerate, has signed a deal with Nanosys for its quantum dot phosphors, specifically to use in mobile phone displays. These could be used by LG Electronics or sold to third parties. The deal is the first commercial application of quantum dots in electronics.
"Our Quantum Rail device takes quantum dots out of the lab and delivers them as process ready components for customers such as LG," said Jason Hartlove, CEO of Nanosys.
The most noticeable effect will be a wider color spectrum in the display, which could be valuable for enhancing image and video experience, both key differentiators for LG's own high end phones. In addition, power consumption is reduced by up to 50%.
Quantum Rail is designed to be integrated into LED backlight sub-assemblies without major tooling changes. Its LED coating technique improves color saturation in backlit screens by applying nanoparticles to a blue LED light. This can enrich color on standalone LED lights but really comes into its own in backlit displays such as those in smartphones and laptops.
