Ortustech outs world’s smallest 1080p display at 4.8 inches

updated 05:35 am EDT, Mon October 25, 2010

New display tech 458ppi vs Retina display 326ppi

Orustech Japan has teamed with Casio and Toppan Printing to develop the world's smallest 1080p display. It measures 4.8 inches diagonally and has a native resolution of 1920x1080 at an extremely high density of 458 pixels-per-inch (ppi). This is a much more densely packed display than the iPhone 4's vaunted 3.5-inch Retina display, which has a 960x640 resolution at 326ppi.

In order to deliver a display of this level of resolution in such a small area, Orustech has developed a new display technology it refers to as Hyper Amorphous Silicon TFT, or HAST. It also has a wide viewing angle of 160-degrees and has support for 16 million colors.

At this stage it has not been adopted for use by any vendors, but Orustech is shopping the display around hoping to generate enough interest that they can put it into mass production. Their suggested uses for the display include applications in HDTV equipment screen monitors, and ultimately smartphones and hand-held video game consoles. The wholesale cost of the technology and economies of scale will determine whether it makes it into production or remains a concept. [via Newlaunches]

    What. Is. The. Point?

    jonbwfc1 is right

    If you can't see the pixels at 326 ppi, with the exception of use in projectors, what's the point of making a screen denser than that?

    This is just for superficial bragging rights.

    jonbwfc1 and hayesk are right

    As the basis of a rear projection monitor/TV, this device would make sense. However, we don't do rear projection any more. There is no technical reason for this device.

    cool, but

    That's pretty cool, but what's the point? There's not much use for a 4.8" screen, cause it's too big for a phone, and too small for a tablet, and with a pixel density greater than what the eye can discern anyway, it's pointless. Take the same tech and make a 7" screen (around 300 ppi) for all these forthcoming 7" tablets, and then you'd at least have a purpose for it (success of 7" tablets yet to be seen).

    When Apple adopts it, it's all cool. Right?

    Trolls are at it

    Funny how people are voting down the comments asking what's the point in going beyond the limits of human vision but yet there are no posts explaining why we would want to do that?

    I love it!

    4.8" is a good size for a phone, that's inbetween the HTC Evo and the Dell Streak in size.

    Oops, I mean only 3.5" is a good size for a phone today, but someday if Apple does a 4.8" size for a phone, then that will become a good size.

    For someone wanting a gorgeous 1080p screen on their phone, this may be the size for them.

    If the phone runs in 1080p and you hook it up to 1080p external output, the display will be the same, no conversion or aspect issues, no black bars, etc.

    It could be that the screen here is a bit more dense than actually required, but over engineering, is, anyway, preferable to under engineering.

    little vision

    so many people with such limited vision of technology!

    Umm how bout an HD field monitor. It would be a great addition to any HD camera, thats for sure. I work at a TV station, and these things would be great for rack mounted video monitoring, multi-source mixing consoles, and more.

    Just because you people have no use for a device, does not make it worthless. I see this as an amazing advance in technology, and think its way cool. It wasn't too long ago that the smallest 1080p monitor was 21" and I'm sorry - but viewing 1080p downsampled SUCKS. The ability to have a pixel-for-pixel rendition of your final content is key.

    Does that mean

    the screen of the iPhone 4 sucks?

    Google should just buy Orustech and Casio. Make some kick-as$ Android Phone screens.

    >>>but someday if Apple does a 4.8" size for a phone, then that will become a good size

    ROFL! Yeah, suddenly it will become a good size.
    Bunch of sheep.

    good for futer screen resolutions

    japan is coming out with a 4320p screen called ultra high defintion that will release 2015. but it has to be over 70in, they can use this technology to make it less then 20in so this is great. and FYI the human eye can see 530ppi so 326 is ok. and someone should come up with 600hz to go on tvs under 40in that would be the top of the line home entertainment and a bad a** gamer expirence.
