    I got to play with a razor for a little bit an what I want to know is there really any difference between the quality of the HD screens? Cuz my personal opinion of the razr was the colors were to dark can anyone explain to me if one screen is better than the other?

    I had the bionic until 2 days ago and thought there wasn't much of a difference myself. Then I got the razr and there is a difference and I am just not saying this because I am now a razr owner there is a difference. You have to take it home and really play with it

    Yes there is a difference. The bionic screen you can see in the sun.

    The Razr is Super Amoled and the Bionic is QHD I believe. Super Amoled has more blacks and greens I believe. I think they both have same pixel density and resolution.

    Oled screens do not have backlights and the pixels generate there own light. This is why amoled phones are so thin. Also why blacks look better and better contrast. This technology will be phasing out lcd screens in coming years

    First off, it isn't really HD unless it is 720p or more. At the moment there are only 3 HD phones: the Galaxy Nexus, the Rezound, and the LG Spectrum. The nexus is OLED and the other two are LCD. (The Razr is OLED too, but not HD resolution)

    There are two main standards; LCD and OLED.

    LCD is the conventional standard. This is like what you've seen in laptops. The pixels are all lit with a lightsource from behind. The pixels themselves block the light...so a pixel that is "off" will show completely white. All you will see is the light part if it. Because of this, you can never get true blacks. If you turn off all the lights in a room, a "black" screen will still glow. LCDs have the advantage of better color reproduction on average compared to OLEDs, just because the tech is more mature.

    OLED stands for "organic LED". The display has no backlight. Each pixel contains biolunenescent bacteria which glow when activated. So when you want black, you just turn them off. Because of this, OLED displays always have deep and perfect blacks. In a dark room, a black OLED display cannot be seen at all. They also tend to be the brightest displays right now and in theory are more energy efficient than LCD. Their main weaknesses right now are ghosting (a trail left behind moving pixels) and burn in (where an image on the screen a long time leaves a shadow of itself after you move it). They also tend to have color banding in gradients and some people consider the colors over-saturated (probably just caused from the contrast with the deep blacks).

    Overall there is no "best" between the standards. Both have merits. When OLED technology fully matures, it will probably surpass LCD, and all the weaknesses listed above will not be there anymore. But it hasnt reached that point yet.

    That was essentially the same comparison between plasma and lcd tvs except you are trying to basically convince people that plasma is better. Everyone knows lcd tv's are better. Same goes between bionic and razr display. Deeper blacks, thinner design, etc does not make them better than lcd

    This is not exactly true. There are no bacteria or other organisms either dead or alive in OLED screens, and OLED screens do not operate via bioluminescence. The "Organic" in "Organic Light Emitting Diode" simply means that the small part that lights up is comprised of a compound which contains carbon. An example of an organic molecule is methane (which is not used to illuminate OLED screens), but again, any molecule which contains carbon is described as organic.

    Most OLEDs use organic compounds with virtually unpronounceable names, Google "OLED"!

    Plasma is better than LCD in many respects. For starters, when was the last time you saw motion blur on a plasma display? Its been a very long time for me if ever. Whereas its evident on every LCD i've ever owned or seen.

    Plasmas definitely look better than LCD. Every time I have to watch an LCD it's hard to adjust. lol

    But the Bionic and Razr screens both have their pros/cons.

    I actually preferred the Bionic at first, because I was used to the brighter whites.

    But now that I've had the Razr for a few months I appreciate the true blacks and more colorful colors.

    Both are the same resolution, and I never had any real complaints about the Bionic's screen for the 1 week I had it. The only complaint I had was adjusting to the smaller text caused by the higher resolution (coming from a Droid X).

    The reason the bionic is brighter is because of the pentile layout of the subpixels. Basically most lcd screens on smartphones have a Red, Blue, Green(RBG) subpixel layout that mix to generate the colors on your screen. Now the pentile layout uses different layouts like adding an extra green subpixel(as on some Samsung phones) or an extra white subpixel(as on the bionic). This naturally makes the bionic's screen much brighter and better performing in direct sunlight.
    here's the wikipedia take on pentile screens: http://en.wikipedia.org/wiki/PenTile_matrix_family
    And here's another article with more info and visual examples: http://www.techthoughts.net/2011/11/14/the-truth-about-pentile-displays/

    UPDATE: After investigation I found that the bionic and text both use the same pentile RG/BW layout whereas I thought the razr had a RGBG like many other OLEDs. So the real difference is just the bionic had the QHD LCD screen and the razr has the OLED screen.

    Not that this discussion has anything to do with the thread, but put an LCD in my living room with floor to ceiling windows and you wouldn't enjoy it until evening....just say'n. No blur, I can watch from any angle, handles sunlight, the list goes on. Heavier yes, slightly less power efficient, yes, but if the kids turn off a light once, I'm ahead lol.
