A 5.2″ HD OLED screen? Yes please.

by: Nate SwannerApril 3, 2013


Japan Displays (JDI) has developed a 5.2” HD screen, sporting a mind-boggling 423 PPI. The company has actually developed this OLED display mere months after announcing a 4.5” display with 326 PPI.

This is comparable to Samsung’s highest resolution OLED panel, the 4.99” display used in the upcoming Galaxy S4. The difference there is the Samsung display is Pentile, and uses a RGBG matrix while the JDI display is true HD. If that was a bit confusing, stay with me.

The RGBG matrix is short for red-green-blue-green, meaning there are two green pixels for every red or blue one (below right). Pentile displays last longer, and often have a better resolution, but also have warmer colors and a visible pattern. A full OLED HD screen uses a ‘real stripe’ matrix to achieve its PPI (think of that leaked Chromebook Pixel video that had all the colored bars on the screen, also below left).

A full HD OLED screen, like the one JDI has created, would be amazing. In addition to the density, it operates on an LTPS backplane, which has a lot to do with screen transition and speed of rendering images. In a nutshell, it’s bright, fast, and beautiful … and you thought we were crazy.

    I would love to see that on the HTC One+?

  • btw, the s4 uses a completely different matrix and GSMarena review has said that there are no visible patterns and it infact looks better than SLCD3 of the HTC One.

  • Master this was the true Oled I was on about!

    There are other things to consider such as the power consumption, ability to mass-produce at a reasonable cost, etc. Since this is not even due for production for a year, Samsung will probably come up with a better one by then given their track record of improving OLED displays over the years.

    From the original new source: “It uses red, green, blue and white pixels as in the case of the previous panel.”

    It’s a RGBW display.

      yes thats true unlike samsung RGBG which has 1 less subpixel than the standard RGB matrix, the RGBW matrix uses 1 additional white subpixel than the standard RGB matrix. RGBW got higher subpixel count, offer higher brightness to the already very dim OLED panels, and offer real white color instead of the blue white usually produced with OLED

  • I’m waiting for flexible smartphone and tablet.

    New Galaxy S4 used diamond subpixels not pentile.

      Wich is rearranged pentile- nothing revolutionary.

  • Jusephe

    Samsung is falling behind in OLED tech.

  • MasterMuffin

    Note 3 with real stripe matrix, anybody? :)

    • This is the oled panel I was on about previously! Amoled is rubbish!

    • Oh, they announced the Galaxy S3 already? *looks online* Nope.

    AndroidAuthority, why your write has insufficient knowledge about this JDI display and still chooses to write this article?

    Well, it’s a RGBW matrix (and not simple RGB), a whitemagic screen. But it is no where mentioned in the article (quite an important fact when you are showing closeup of pixel pattern!)

    and unnecessarily praising samoled pentile “…often have a better resolution”…
    Really ? you should rather say samsung was unable to pack proper rgb for FHD in 5 inch that’s why this pentile!

    and at the end he goes defending himself “…you thought we were crazy…”, for the article where he got many kicks!
    WOW! how professional!

    hey look again, Samsung had done it already. Galaxy S II- RGB, Galaxy Note-RGBG, Galaxy note II-Complex RGB, Galaxy S IV- Hexagon Matrix. How is this Mind Boggling?
