Apple may not have invented high-DPI IPS panels, but those panels wouldn't exist outside of the lab today without Apple. Smartphones were pushing 300 PPI+ before Apple decided to try to brand it. http://www.tgdaily.com/hardware-features/52181-worlds-smallest-hd-display-hits-1920-%C3%97-1080 http://www.tgdaily.com/hardware-features/52181-worlds-smalle... That display packed 1920x1080 on a miniscule 4.8" display. Further, the iPad was a serious laggard behind much of its tablet competition -- whose greater PPI was never heralded as any great innovation -- but suddenly they play leapfrog and invent a whole new industry? Give me a break.

That link you posted is talking about a prototype, not a mass-production device. And what smartphone prior to the iPhone 4 had even 300dpi? The closest I can find reference to is a 3.2" 480x800 (291dpi), and back then, Android didn't support higher resolutions. Nobody's claiming that the 1024x768 iPad screen is significant, but the 2048x1536 version definitely is a big advance.

  The only reason that we haven't seen high-resolution display on the consumer market before the iPad 3 and iPhone 4 has to do with software support and nothing else. This was a direct result of the LCD since the resolution on an LCD is fixed the only way a consumer could increase the number of pixels on a device was to get a larger device (display). And Apple have taken the easy way by scaling the solution by four so that scaling the graphics is trivial. Not saying that it's a bad way, it has advantages and disadvantages but doing it the simple way is the quickest way to make way for high resolution devices.
