Inspite of the awfully brilliant picture quality and the elegant sleek looks, LCD TVs have always faced the problem of delivering that startlingly perfect black. Deep blacks without a hint of grey are quite a rarity in the world of LCD Televisions. There was a friend of mine who complained that in his LCD TV, the night sky always looked turbid. “It’s haunted, I tell you. The darn thing has a grey cloud over everything dark.” Well, that could be an overstatement, but then one can’t deny the thread of truth in it. Contrast suffers too and some LCD TVs have problems dealing with motion.

Coming back to black levels, Sharp Corp has recently said that it has developed a new technology called UV2A that will ‘evolve LCD TVs to the next generation.’  According to Sharp, this technology will be able to produce extremely deep blacks and display vivid and bright colours. Not just that, this technology will also save energy while doing so by facilitating the use of light from the backlights. The UV2A technology will apparently render contrast ratios 60% more than that of the conventional panels.

This technology will be first in the world, and functions by controlling the alignment of the liquid crystal molecules in a simple LCD panel in response to ultraviolet radiation. Though there is no word about when Sharp LCD TVs incorporating this technology will be available, Sharp has indicated that this technology will be used to produce LCD panels in its plants in Sakai and Kameyama.
