JDIs new 1920 x 1200 7" display could pave the way for efficient high-res 7in tablets

Japan Display Inc. has announced the development of a seven-inch WhiteMagic WUXGA (Wide Ultra Extended Graphics Array) LCD display. The display has a resolution of 1920 x 1200 pixels and features WhiteMagic technology that incorporates adding a white subpixel to the RGB pixels to better control the brightness of the LCD.

WhiteMagic display technology was first seen in Sony’s flagship handsets a couple of years ago. This will be the first time the technology is being used in a larger display with the main benefit being that it can reduce power consumption up to 40%. JDI is currently shipping samples of the seven-inch display, which would ideally be used for tablets.

Japan Display Inc. WUXGA display specifications:

  • Screen size (diagonal) 7.0-inch (17.8cm) 
  • Number of pixels 1200(x RGB) x 1920 (WQHD)
  • Resolution density 323ppi
  • Dimensions 98.7 mm (W) x 160.8 mm (H) x 1.8mm (D)
  • NTSC ratio 72 %
  • Contrast ratio 1800:1
  • Viewing angle >160 degree (CR>100:1)
  • Surface luminance 500 cd/m2 (low power mode) 1000 cd/m2 (outdoor mode)

As a supplier of displays for Apple, JDI announced an even more impressive LCD, which is rumored to be in production for Apple’s upcoming handset, the iPhone 6.

This doesn't sound like new tech at all. It sounds like PenTile with a white sub-pixel (rgbw), which Motorola used in their smartphones a few years ago.

It looked like utter crap (imagine viewing your screen through a screen door).

Sony have always had gorgeous screens.....

Xperia Z had the worst screen I've ever seen in years (meaning flagships in comparison).

Good for you. It was a common complaint with earlier Motorola Android devices. They also stopped using it, so obviously it wasn't having a positive impact on people.

The most IMPORTANT part:

This will be the first time the technology is being used in a larger display with the main benefit being that it can reduce power consumption up to 40%.

1080p is standard for smartphones now and it works, this is perfect for 7" too.

this is NOT about the resolution guys!
this is about WhiteMagic display technology which is AWESOME!!

Keep you resolution complaints to LG G3 phone please (1440 x 2560 pixels, 5.5 inches (~534 ppi = now that is ridiculous and will eat the battery for sure)
This display has 323ppi which is perfectly normal nowadays and is expected.

That resolution rush...
It fits quite fine for the 23-24" display, who needs it on 7"? (except marketing addicts ofc)

actually, i think this size is perfect for the seven inch. just like 1080p is for 5 inch.

i am glad they did not put anything stupid res wise here.

wish it was 8 inch though... as i am super happy with my 5" phone as primary device, so for a tablet, i want to see 8".... 7" is just too similar.

You'll barely see any difference between 720p and 1080p on 5", but battery consumption differs greatly. It's all marketing bulls...

tablets and phone you hold closer to your eyes in general, I agree with you on the phone front as we're already high enough and the new androids announced with 4k is just stupid.

This give 330PPI which I think is the absolute most you'd want/need on a tablet.

Sorry but I disagree with the first part. I'm a programmer and I'd greatly appreciate a higher resolution on my 21", not to mention a 24" widescreen. The whole part where desktop LCDs started adhering to standards laid out by TVs didn't do *anyone* a favor.

Even 2k on the new LG is stupid, especially powered by a 3k battery. It seems to be a wall-mounted phone :)
As for the tablet - FullHD works absolutely great on 10", you don't need any higher unless you take a looking glass.

Working on a LG 29 EA 93, doing graphics and mapping, 1080p is pretty fine (but it's ultra-wide). Consider taking a fresh IPS one, it will hurt your eyes much less.

Exactly the point I was making, but after using 1080p for a month, and then swtiching back to 720p device, the display looked like crap.

remember also, that most of the web is optimized for 1080p, so having 1080 phone is very nice to display the web (not directly mobile sites) properly.

anyway, i changed my mind, 1080p is better, but seriously, no need to go further, as images on screen are sooo tiny,.

yes, and this one has 323ppi = perfectly normal.

This is about the technology behind the screen, not the resolution FFS!

If it really is that magic as said, that'd be great.
Agree at this point.

i agree with you on 1080p on tablets. however on 21-24" screens the higher resolution is very helpful. Of course the IPS is important. But any graphics pro is already using an IPS screen! Higher res on 20+ plus screen is essential for fine graphical work, you can fit a lot more stuff on higher res screen, and still see it fine.

LG 29" 2560 x 1080 is good for some work, but can still be improved on tremendously. If you sit close to it, and do fine work, you are better of with 2560x1440.

even if not for editing, but for layout of the tool panels in photoshop itself ;)
(though, with your superwide screen you probably have it covered)


Lets agree to agree ;)

I got another one for all the panels, this one is for work only :)
Agree on agree to agree :)

It looks great on my Nexus 7. It was very noticeable going from a v1 Nexus 7 @ 1280x800 to a v2 @ 1920x1200. Huge difference in text rendering.

remember also, that most of the web is optimized for 1080p, so having 1080 phone is very nice to display the web (not directly mobile sites) properly.

Most of the websites isn't fully rendered at 1080p. Partly because you are using phone with a smaller display such as 5 inch 1080p that can hardly feel any differences. Try use it on bigger display such as iMac and you notice majority of them opted at 1024X768. In fact, very few sites actually scale across different resolution.

You forget most people view in portrait mode, making it a 1200x1920 long view of a web site. 1024 wide and 1200 wide are very close. Double-tap to zoom also means getting an optimized view of an article on a tablet is fairly simple.
