LG eggs on the spec race with the world’s first 1440p display


Have you ever looked at your smartphone and said, “Man, I wish this display was 1440p.” Probably not. In fact, 1080p is extravagant to many people. But the specs race can’t be stopped, and LG has just become the first manufacturer to create a smartphone display with a resolution of 2560 x 1440. To put that in perspective, most people’s TV’s are 1080p. The same goes for computer monitors, and for that matter, many laptop displays aren’t even 1080p.

Be that as it may, this is going to be an incredible display. At 5.5-inches in size, it features a pixel density of 538ppi. The display is also set to feature class-leading contrast and color reproduction. And will it ever be bright; the display will feature 430 nits of brightness. In terms of size, it’s also the world’s thinnest panel (1.21mm thick) and has the narrowest bezel (1.2mm). So if you like pixels and don’t mind looking at LG’s software, this display should probably be in your next phone.

Do you think that a 1440p smartphone display is overkill?

LG Display Develops World’s First Quad HD LCD Panel for Smartphones
New panel will deliver optimal viewing experience on larger smartphone displays

Seoul, Korea (August 21, 2013) — LG Display [NYSE: LPL, KRX: 034220], a leading innovator of display technologies, announced today that it has developed the world’s first Quad HD AH-IPS LCD panel for smartphones. At 2560X1440 with 538ppi, the new 5.5-inch Quad HD panel is the highest resolution and ppi (pixel per inch) mobile panel to date, and provides a glimpse at what’s next after current Full HD smartphone panels, critical given the growing trend towards larger displays.

“LG Display, which pioneered the high resolution mobile market with introduction of the world’s first Full HD smartphone panel in 2012, again opens new possibilities with the successful application of QHD technology,” said Dr. Byeong-koo Kim, Vice President and Head of LG Display’s IT and Mobile Development Group. “With this breakthrough, LG Display will continue to raise new standards for mobile resolution and lead the mobile display market.”

LG Display’s Quad HD panel for smartphones realizes clearer images with 4 times more pixels than HD at 1,280X720, thereby reproducing more delicate colors as well as improving contrast and vividness when compared to current mobile displays. This advancement will enable consumers to fully enjoy more life-like and crisp images, and even Blu-ray equivalent video, on their smartphones. The panel also features the highest ppi among current mobile device displays.

In addition, the new Quad HD panel will enable users to enjoy a full view of PC-version web pages at a single glance without image distortion; a contrast to current Full HD displays which only realize 3/4th of a full screen. Also, even when enlarging the screen, users will be able to enjoy undistorted and sharper text.

Only 1.21mm thin with a 1.2mm bezel measured in LCD modules (LCM), LG Display’s new Quad HD panel is both the world’s slimmest and narrowest panel, with 12% reduced thickness compared to the company’s 5.2-inch Full HD panel released last month. Based on Low Temperature Poly-Silicon (LTPS) substrate, the panel also realizes superior brightness of 430nit with improved transmittance and larger aperture opening size.

LTPS-based smartphone displays are expected to record 765 million units in shipments next year according to research firm DisplaySearch, as displays with larger screens, higher resolution, and less power consumption prove key to competitiveness in the premium model segment.

    Thats all this is.

    Unless adding more pixels increasing battery life, I’ll pass. Why don’t manufacturers get it that consumers want better battery life. While that may not be happening that quickly, putting in extra pointless battery draining pixels that aren’t even perceivable is just silly. Anyone putting this in a smartphone should be strung up by their toes.

      Really what we need is better batteries. Someone needs to put the money into something like super capcitor batteries and start the change.

    • jonathan

      I think you’re absolutely right, and also wrong.

      People want their cell phone – their current cell phone – to last longer on a charge. I bet almost everyone will agree with you.

      BUT, when people go to the store, and look through the devices, I’m guessing many other things suddenly compete for their attention/concern: camera, display, feel, etc. Except for a small niche that REALLY needs battery, most battery conscious users might make the effort to look for some info, but (again, this is just what I’m guessing), a bulletpoint from the carrier, reseller or OEM that says “All day battery life!” or “Ten percent better battery!” or something would be enough to suffice.

      The new Xperia ZU had similar bullet-points during and after their press release: 3000 (3k something, I don’t remember what) mAh battery! To most people, they have no idea what that means but a comparison to other phones will make it sound good. On that note, reviews I’ve read seem conflicted about the ZU’s battery life, but with a 6.4″ 1080p screen, 3,000+ sounds too low.

      I thought it was crazy when we went to 1080 for high-end, but I like the GS4 and HTC One screens a lot. Like the author said, I guess it’s unavoidable, but I still wish we could just stick with 1080×1920 as the norm for the next few years and focus on battery life, screen tech (thin, color reproduction, etc), and GPU. With resolution constantly skyrocketing, I’ve barely noticed the advances in mobile GPUs starting with the GS1 (captivate).

    Pixels are so tiny we are only going to have to take LG’s word on how many actually exist in that panel. My sub-HD smartphone is REALLY starting to feel old now.

  • Joel

    It’s just stupid. Their isn’t even any content for some crazy pixel number. Its either 1080p or 4k or 8k. And even in full size TVs 4k is useless under 32″ so their just being dumb. There just isnt any content for that spec. No videos, no games nothing. More power to them. In the past phones with ratios that were not normal haven’t done well because apps didn’t work with them, hopefully they at least have software in place that will handle the 720 & 1080p content that’s available. The panel made by sharp in my HTC one 1080p 468ppi is even a little over kill but it is a beautiful screen. & a difference can be seen when side by side with a 720p screen so in my boon if I can see it it’s wore it. So if I put this screen next to mine & can see the difference I may change my mind. But I think were here go levels even my good eyes can see.

    The images of Asian characters provides a very powerful reason for higher PPI, great post that completely changed my mind
    about this tech.

    On a side note anything that pushes the boundaries of tech should be applauded even if this is not needed for phones imagine Google glass or VR headset where the panels are smaller and much closer to the eye?

    Awesome work I say.

      Hopefully but probably too soon.

    1080p. Okay.

    1440p. Piss off LG, your making it harder and harder for us as Developers!

  • ufmace

    Interesting point. The English letters look pretty good at the “low” 326 ppi (though just how small is that font?), but the Japanese characters look butt ugly.
