Retina display
The phrase retina display is being used a lot these days. My reading indicates that the vendor uses this term quite loosely [1]. There you can see that the definition currently ranges from 326 to 220 ppi. The resolution of the XO's display is listed as 200 dpi [2], which is not far off. If I have understood correctly, dpi in the context of display technologies is the same thing as ppi [3]. Without infringing any trademarks, how closely could we say that the XO's display is a retina one?

Any question on characterizing the display should probably be referred to Mary Lou Jepson (now at Pixel Qi). http://www.pixelqi.com/ IANAL, but the term Retina in reference to computers and mobile devices is an Apple trademark, so any such use (referring to anything but an Apple device) would be violating their rights to that mark. cjl ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Re: [OLPC-AU] Retina display
Don't go there. It is hard to talk about the resolution of the PixelQi display. In BW mode, it is 1200 x 900.In color mode, it is something closer to 690 x 520, but the human visual system has much less color resolution anyway so it appears sharper. MLJ did a great job of matching the display to the HVS.
