It’s known that manufacturers of new screen panels use PenTile style for their screen, like the latest Motorola Atrix 4G’s qHD screen. Unlike traditional displays (CRT, LCD, plasma, you name it) typically use one red, one green, and one blue subpixel per pixel, and the end result is that AMOLEDs and Super TFT and what not, they tend to be a little grainier by comparison at a given resolution. That’s because of their little visual trickery whereby green subpixels occur with greater frequency than red and blue. Apparently it’s cheaper to manufacture and also saves more on the electricity.

OLED-Info points out that Samsung’s new Super AMOLED Plus displays appear to have solved the PenTile problem, instead using something called Real-Stripe — effectively meaning honest-to-goodness RGB pixels, which explains the company’s claim back at CES of a 50 percent boost in subpixel count. Interestingly, Real-Stripe requires more space per pixel, which could be why the Galaxy S II and Infuse 4G are 4.3 and 4.5 inches, respectively, a pretty healthy hike from the 4-inch mark they’d settled on with last year’s original Galaxy S models. ‘Course, none of this puts us close to the 7 or 10 inches we’d need to make a tablet work — but we know they’re cranking on that already.
