Looks like Samsung has one-upped Sharp. The latter announced a handful of high-PPI notebook screens last week, but now, Samsung is about to demo some even higher-density panels at the the Society for Information Display's Display Week event in Vancouver, Canada.
The Samsung screens include a 10.1" display with a 2560x1600 resolution, which works out to a whopping 299 pixels per inch. Even more excitingly, there's a 13.3" notebook screen with a 3200x1800 res. That adds up to 276 PPI, even higher than the 227 PPI of Apple's 13.3" Retina MacBook Pro. (That system has a 2560x1600 resolution.)
Insanely high pixel densities aren't the only selling point of those panels. Samsung claims its new babies "each can deliver 30 percent greater power-savings than that of existing LCD tablet displays, by decreasing the number of driver circuits and increasing the efficiency of the LED BLU [back light unit]." High-PPI screens tend to require more juice than their lower-density brethren, so that's good news.
In case you missed our report last week, the Sharp displays we talked about included 11.6" and 13.3" offerings with a 2560x1600 resolution, plus 14" and 15.6" panels with a 3200x1800 resolution. Pixel densities were 253, 221, 262, and 235 PPI, respectively. That's still desirable, no question about it—but Samsung may have taken back the high-PPI crown, at least when it comes to notebook screens.
