Why not Anti-Reflective coating for LCD HDTV ?

Mmm Plasmas are reflective cause the screen is actually made of glass (last time i checked), instead of plastic on LCD.

 

Because, while antireflective screens may actually reduce the amount of light reflected – compared to coatings that attempt to disperse the reflections – the perceived effect is somewhat opposite. When the screen is dark, a high-gloss anti-reflective LCD us basically a mirror, and I can easily see how this might be objectionable to many users under typical lighting conditions when, say, watching dark scenes in a movie.

Now, under ideal conditions it would bring an improvement, but I don't think the tradeoff is worth it on TVs (on laptops/PC-monitors, on the other hand, the marked has (understandably) decided different, but I still wish for a matte screen sometimes when watching movies on travel).

 

My guess it's sort of like the BrightView option you see on notebooks.

The glossy reflection makes the LCD seem more black when the room is lit, as it doesn't scatter part of the incoming light towards the viewer. Unfortunately, when a light is directly behind you, then you do see a reflection and need to change your TV's orientation or your viewing position. That's where the matte anti-reflection coatings are better, because they diffuse everything. For TV's it's good to have the matte anti-glare because you might have windows or lamps behind the TV that give an annoying reflection in an anti-reflective coating. Putting AR on a TV might result in more returns.

In my office I was shocked how good my notebook's LCD looked compared to the CRTs with the lights on. Once you turn the lights off, however, it's a completely different story, with the CRT being almost pitch black and the LCD emitting a nasty blue-grey. AR would definately sell notebooks and LCD monitors in, say, Best Buy.

 

Most if not all plasmas have a plastic coating over the glass. This plastic coating can be made to function as a AR filter if needed.

AR coatings have been used on eyeglasses, binoculars, camera lenses etc for decades. The problem is you can see almost everything reflected off of the high gloss coating if there is any ambient light around.

 

IMO

I must say that I reeaaly don't like those glossy screens. A friend has a laptop with such a screen, and yes the blacks can be really black. But every time he want's to show something, I have to bob around my head to find a spot where there are no reflections. And usually, I need to move the head when I want to see another part of the screen. The only environment where it would work is a pitch black one. (And then there would be no use with any anti-reflective coating.)

I'd take Anti-Glare treatment over that any day.

 

True but the matte finish of AG treatmeats causes slight blurring that the gloss screens don't in a dark environment. They both have their advantages/disadvantages.

 

i was wondering what the difference was between ag neovo's patent pending neoV optical glass, compared to things like nec's opticlear, and sony's xbrite?

that may be a stupid question, but i'm asking people who know more than i do.

anyways, my nec opticlear (20wgmx2) was disappointing b/c it has poor blacks, when it was supposed to have great blacks.

do pva panels without an opticlear equivalent have better blacks?

i think my opticlear is an as-ips.
