[size=1.125]A collaboration by Peter Palomaki & Matthew Bertram
[size=1.125]LG, known mostly for their OLED display technology, has recently been promoting their new LCD technology called “
Nano Cell.” While the exact inner workings are a closely held secret, this technology is of interest to the display industry because it is being promoted as a novel way to increase color gamut and improve viewing angle. But what exactly is it and what does it do!? We have some speculation as to what LG is doing to differentiate their LCD line of displays to compete with Samsung and others who are adopting quantum dots to achieve wide color gamut (WCG).
[size=1.125]Color gamut has become an important specification in the display industry in recent years. Display companies have explored many different technologies in order to improve color gamut including narrow red and green phosphors, quantum dots, color filter improvements, even the liquid crystal itself. We took a deep dive into patents and literature, as well as characterization of an actual Nano Cell display in an attempt to better understand exactly what technology is being used, how much it improves color, and what about it is “nano.”
So What Exactly is this Nano Cell Technology?
