Customers are welcome to replace their device, though, at service centers in Korea. The 5. Samsung's display probably uses some sort of PenTile architecture , though, so actual sub-pixel count is smaller. Read the full story Posted: Nov 13, Tianma shows a 5. This is the highest-resolution display ever shown by the Chinese display maker, and reportedly they have adopted a subpixel scheme not unlike Samsung's Pentile technology.

To achieve the high resolution, Tianma developed a dual-FMM technology in-house. Tianma has plans for three separate OLED production lines.

As these displays are very similar to the GS5 display, it's not surprising that DisplayMate found those tablets to offer the best performing displays ever. These are also the highest resolution tablets at QHD. When Samsung first released the GS5 , we thought the 5. They also incorporated new display electronics and optics and that helped as well.

But now Chipworks posted a teardown of the GS5, and they published a macro image of the display's sub pixels. It turns out that it's a different architecture than the GS4, and this may explains some of the performance boost, too. The company refers to this new technology as Z-Type arrangement and it includes 3 sub-pixels RGB per pixel unlike Samsung's Pentile displays. The sub-pixels are densely packed the aperture ratio seems very high in a way that does not suffer from jagged edges.

Visionox told me that they cannot yet say when such displays can be commercialized, as there are still manufacturing challenges to overcome. In the meanwhile the company applied for both Chinese and international patents. Skip to main content.

I went into some of these in my article ' Why LCD is now a better choice than AMOLED for smartphones ' recently, but one of these is that longevity takes a hit because the blue sub-pixels in particular degrade in intensity with use.

I examined the degree to which this is true here. Instead, by halving the relative number of red and blue pixels, shown diagrammatically above and photographically below, the lifetime of the display can be extended, perhaps from a year to several years of good performance. Contrast this to many years for LCD, of course. In the absolute worst case, for displaying blocks of red or blue, you'd then be dealing with half the quoted resolution of the screen, i.

However, rather obviously, when displaying blocks of colour there's nothing complicated or with fine detail to show, so this drop down makes no difference.

For real world photos, icons, text and other layouts, with a mix of colours and textures, clever electronics behind the screen, allied to support from the Windows Phone OS, 'sub pixel rendering' is used similar in concept to the anti-aliasing used on desktop and laptop screens , combining output from combinations of sub-pixels in the layout shown above in order to show finer detail than you might think. At best, this can approach the full resolution of green sub-pixels e.

When 'pentile' displays are criticised, the criticism is therefore rarely about the resolution of displayed content - the 's presentation of photos and other graphical content on its p pentile display is indistinguishable to the naked eye from the same on a p RGB LCD panel. Criticisms of pentile usually centre around 'fringing' on the edge of solid blocks of colour and sometimes text, depending on the font being used.
