Present day, high-end Android smartphones are offered in two display resolutions: 800 x 480 (WVGA) and 960 x 540 (qHD). With the upcoming release of Ice Cream Sandwich (ICS), we expect the high-end Android phones to embrace even higher resolutions including 1280 x 720.

Samsung already announced a 720p version of the Galaxy S II, and the upcoming ICS launch vehicle is widely expected to boast a 720p display as well. As a prominent LCD panel vendor as well as a player in the smartphone space, LG is hopping on the 720p Android bandwagon with the Optimus LTE.

The Optimus LTE uses what LG is calling its True HD IPS display. The True HD IPS panel measures 4.5-inches diagonally and has a pixel density of 329 ppi courtesy of its 1280 x 720 resolution (slightly higher than Apple's Retina Display at 326 ppi). Todays release doesn't reveal any other panel specs, but we do have a few shots of it below courtesy of LG.

Like the Galaxy S II HD LTE, the Optimus LTE is being introduced first in Korea.

    i checked it here

    but what about the maths
    and those formulae
    why dont u
    do the maths
    So what is the exact screen size then ????

    It says ~330ppi, the tilda means approximately, I think I'd believe and wikipedia values over gsmarena. I have done the math, if you use 9cm and convert it to inches you get 325.6 ppi as I said, rounded up to 326.

    It's an incredibly small difference but if you want to go calling people out on bad math and throwing in smiley faces and "dude" to make it seem like you're not just nitpicking go ahead.

    The thing is that their math was just fine, as was yours, but you don't respect significant digits. 3.5" could mean 3.450 to 3.549 inches, if they're working it out as 3.543 inches (9cm) you get 326ppi. And all of this is assuming square pixels (not always the case, although the iPhone does seem to have them).

    Panel available for about a year :)

    These high resolutions displays are rather pointless imho, as they don't offer any advantages over the currently available ones.

    We could argue back and forth about the "retina-thingy" but truth to be told anything above 300 dpi isn't going to add anything. Most computer-screens have something between 72 and 96 dpi and they're totally fine with this "low" resolution allready and you need to be closer then the length of your arm to really see single pixels and get a dizzy image.

    I've got an old mobile with a 4" screen and 640x320px and it's totally sufficient allready imho. But then again, I'm using my mobile to make calls or maybe read/write an eMail or SMS. I simply can't be bothered to surf the web on a 4" screen, when I've got 10" tablets and 11" subnotebooks around.

    I have 15inch dell xps laptop that is full hd 1080p
    even after using it i feel the resolution is tooo much for a 15 incher
    and i feel that any screen less than 14 or 15 inch having a full hd screen would be superfluous
    and anyways playing a full hd 1080p video on a 7 inch or any screen less than 15 is not going to get you the actual quality of that video
    you are surely gonna miss out on the viewing experience
    What i feel is
    lets not get into the rat race
    which the recent digital and phone camera's have been in
    just increasing the megapixels in camera's dont gets you the best quality
    optics are much more important than just megapixels
    Same should be the approach for displays too
    just increasing the resolution is not a solution to it
    we should also give more importance to the display technology tooo
    n i feel anything above hd in a 4 inch phone would be just waste of pixels
    and GPU power tooo
    Hope soo these manufacturer get my point :)

    PPI is a completely irrelevant metric on its own, for smartphone the actually interesting metrics are display size and resolution. PPI merely helps to give an idea of perceived sharpness.

    Personally I feel that most desktop displays have too low resolution given their size, I'd be very happy to see a 2560*1600 or 2560*1440 resolution on affordable 20-22" displays.

    Anyway, 720p makes a lot of sense to me on a smartphone as it would allow for native display of a lot of HD content. Such as TV shows.

    As well as allow for a better web browsing experience, obviously.

    720p on a 4" screen is total bollocks and doesn't improve your experience of viewing movies or browsing the web, if look at it in a reasonable distance.

    At 40 cm distance - which would be the length of your forearm - you can't distinguish single pixels whe the density is higher then 150ppi, so yeah higher resolution is pointless, no matter what.

    When talking about HD-content then the best way to deal with it on small screens like mobile phones is to simply render a 720p video at only 360p, i.e. half it's resolution, and you won't even be able to tell the difference at those 40-50 cm distance. It's simple physics and capabilities of the human eye.

    Look at magazines in that regard, which are usually printed in 150-200dpi, and nobody would actually say that the image-quality of Playboy or the like is bad.
  • kishorshack - Monday, October 10, 2011 - link

    Totally agree with you dude
    anything above 720p on a 4inch phone will be useless
    Why dont people understand that our eyes do have some limitation

    Rather display technology should be given more preference than just
    the resolution
  • Iketh - Tuesday, October 11, 2011 - link

    "Dude" i'm already sick of reading your ignorant comments.

    Bring on the 500ppi screens. That is close enough to the limits of our eyes, NOT ~300. I most definitely notice the difference, I'm sorry you're handicapped. Manufacturers, don't listen to these egotistical idiots that think their opinion speaks for everyone.

    Who holds a smartphone at arms length? When I'm browsing the net before going to sleep its at perhaps 20cm.
