*dazed and confused*. And I hate squinting.

In 2012 (I whimsically call this "The Year of the Mirror" under my breath), it was hard (or impossible) to tell what the facing glass had for reflectance / specular-reflectance issues from spec sheets.

And I'm not seeing any consistent metric showing up yet for comparing these things. Does it exist for the TV arena?

I read here and there that taking anti-glare out of the equation usually increases CR ratings, which was maybe driving this.

Back in October 2012, Sharp announced their first TVs using Moth-Eye. Seems truly impressive, and reminds me of Museum Glass---the uber expensive stuff for picture framing.

But what is impressing people other than Moth-Eye, and what's likely to show up inexpensively, if anything?

Nothing soon and nothing inexpensive, alas.

And if the OLED prototypes are any indication, we're going to have TVs that are as glossy/mirror-like as the flagships from Samsung have been, which is to say "very".

Maybe next year....

And you may ask yourself well how did I get here?
And you may ask yourself am I right? Am I wrong?
And you may say to yourself yourself: What have I done?!

For anyone interested, I find the following wikipedia article to be one of the better write-ups on anti-reflective methods.

Here's the section on interference coatings.

This little bit of counter-intuitive wizardry actually caught my attention (for non-normal incidence causing a phase decrease):
Quote:
If the coated optic is used at non-normal incidence (that is, with light rays not perpendicular to the surface), the anti-reflection capabilities are degraded somewhat. This occurs because the phase accumulated in the layer relative to the phase of the light immediately reflected decreases as the angle increases from normal. This is counterintuitive, since the ray experiences a greater total phase shift in the layer than for normal incidence. This paradox is resolved by noting that the ray will exit the layer spatially offset from where it entered, and will interfere with reflections from incoming rays that had to travel further (thus accumulating more phase of their own) to arrive at the inteface. The net effect is that the relative phase is actually reduced, shifting the coating, such that the anti-reflection band of the coating tends to move to shorter wavelengths as the optic is tilted. Non-normal incidence angles also usually cause the reflection to be polarization dependent.

Keep in mind this is Wikipedia, but even without enough references the article reads well as a compilation IMO. There's a far too small section on Moths' eyes as well.

The least reflective (non reflective) is a CRT-RPTV with the protective screen removed. You can pick up a used one for cheap to hold you over. I'm still watching my 73" Mitsubishi.
