LG U+: The LG Optimus Big is an Android 2.2 smartphone with a fairly large 4.3-inch TFT LCD dubbed Nova Display. The unique feature of the Nova Display is a brightness of 700 nits. This is how LG did it:
Ok-Hyun Jeong, Head of MC R&D Center at LG Electronics shared durÂing the 2011 LG Techno Conference that is going on right now in San Jose, Cali., that the NOVA LCD makes use of the companyâ€™s Fine Black Matrix technology, which reduces the thickness of the TFT from 9 microns to 7. Less light blockage means improved light transmittance and thatâ€™s how LG is getting to a retina-burning 700 nits of brightness.
LG is also touting that the company was able to reduce power consumption by 50% on the Optimus Big. My guess is the higher light transmittance on the Nova Display allows you to do two things. One, use the maximum 700 nits on a sunny day outside. Or two, bring down the brightness to a more reasonable 500 nits and save a lot of power. The display generally consumes the most power on a smartphone so tweaking it leads to some great power savings.
