Slates with ultra-high-density LCD panels are coming... eventually. Just as rumors regarding an iPad with a "retina" display were beginning to simmer down, Engadget has posted details about a Samsung presentation that casts some (indirect) light on the subject.
The presentation includes this rather telling slide highlighting Samsung's slate LCD roadmap for the next four years or so. Apparently, panels with 130-170 pixels per inch are coming in the near term, with 200-300-ppi models featuring optional, glasses-free stereoscopic 3D to follow. Later, we'll apparently get to enjoy panels with pixel densities as high as 400 ppi. Battery life will purportedly increase along the way, too.
As you might recall, Nvidia demonstrated the successor to its Tegra 2 system-on-a-chip, Kal-El, driving a 2560x1600 display last month. 2560x1600 happens to be roughly the amount of pixels you might see on a 10.1" display with a 300-ppi pixel density. Clearly, there's plenty of momentum behind the push for slates with high-density displays.
I'm just hoping this momentum will eventually propagate to desktop LCDs. Give me scaled-up 1080p video and games all you like—I don't mind—but please, please let me have sharp text that hasn't been smudged or distorted by clumsy font antialiasing schemes.
