"Advanced Super View (ASV) - This technology was developed by Sharp for use in some of their TFT displays. It consists of several improvements that Sharp claim to have made, mainly to counter the drawbacks of the popular TN Film technology.
They have introduced an Anti-Glare / Anti-Reflection (AGAR) screen coating which forms a quarter-wavelength filter. Incident light is reflected back from front and rear surfaces 180° out of phase, thus canceling reflection rather diffusing it as others do. As well as reducing glare and reflection from the screen, this is marketed as being able to offer deeper black levels. Sharp also claim to offer better contrast ratios than any competing technology (VA and IPS); but with more emphasis on improving these other technologies, this is probably not the case with more modern panels.
Ultra Wide Viewing Angles - Offering wide viewing angles of at least 170 in all directions. This is like VA and IPS technologies do, but Sharp claim that this doesn't impact response time as much as other technologies do. This is achieved thanks to a specially designed cell structure, which supposedly offers blur free images on moving video. It is interesting to note that Sharp's description of this technology doesn't mention gaming, only that fast moving movies are fine with their ASV displays. There are very few ASV monitors around really, with the majority of the market being dominated by TN, VA and IPS panels."
