AMOLED Observation / Question

[RichSz]

AMOLED screens, as I understand them, consist of separate LED pixels (or sub-pixels if you consider each color) which emit light directly and therefore need no backlight. The key pieces to my point are LED emit directly.

Yesterday I was in my car waiting for someone with my polarized shades on when I noticed that as the angle of my head changed relative to the screen, the screen changed brightness. I expect this with an LCD screen since it works on polarized light, but why would a LED screen need to polarize the light?

Makes me wonder if the GNex has an LCD screen.

Okay, so hold up here. I get wanting to ask questions about things.

But do you honestly, seriously, believe that Samsung, Google, Verizon, and other companies are lying to the entire world about something that is easily verifiable within two seconds of turning on the device? And even if it were not verifiable by simple observation, that nobody would take the device apart to discover what kind of display it has?

Really?

No, it's not an LCD screen. It has no backlight. You can tell by simply pulling up a black image on your screen - an LCD screen cannot display a true black because the backlight always has to be on. On an LCD display, a black image is simply very dark grey. Pull up a black image on your Droid X and turn off the lights - you can actually use it as a flashlight. Then do the same on your Nexus.

I'm not an expert on displays, but it's not only backlight LCDs that require polarization. Old style LCD displays that do not emit light (e.g. clocks, or many dashboard odometers) are polarized.

AMOLED - Wikipedia, the free encyclopedia

Samsung has marketed their version of this technology as Super AMOLED. Clear Black Display or CBD is an AMOLED display with a polarized filter on top.

Wow! You're reading very deeply into one offhand comment. Take a breath, calm blue ocean.

I never said anyone was lying. I stated what I understood and observed, hoping someone would correct me as your following post does. That's why I said "wonder" instead of stating my confusion as fact or accusation. Sorry if it came across differently.

While I don't appreciate your somewhat condescending answer in this post, I do value the clarification in your next. Thank you for that, it's all I was looking for.
