An Apple a Day Keeps the Ophthalmologist Away

June 8, 2010

Yesterday at 19:00 there was an Apple keynote by it’s CEO Steve Jobs. Like any good Apple fanboy, I followed it on the web. One technical upgrade to it’s newest iPhone version got my attention right away. A 326 ppi screen called Retina Display! Throw a moniker like that at an ophthalmologist and you can be sure of his critical attention. Jobs postulated that 300 ppi is above the cutoff resolution of the human eye, conveniently forgetting to take viewing distance and eventual enlargement factor into account. But sure, at normal reading distances, and those of us over a certain age can’t see any nearer, the eye can’t resolve individual pixels on this screen. Dithering at rounded contours of, for example, letters shouldn’t be visible. The screen has 78% of the pixels compared to the iPad’s, but they didn’t fall into the trap of making iPad apps run on the new iPhone 4. That would have led to itty-bitty UI elements and text and a total loss of touch usability.
Nothing was said of the screen’s bit depth, so I’m assuming it is still an 8-bit device.
This leads me to another claim that S. Jobs made regarding the Retina Display. He compared it’s ppi with a laser printer’s dpi of 300. Not to pun too much, but that was the real eye-opener! A screen image as sharp as a laser printout, or even sharper, because pixels can’t diffuse out as dots on paper do.
I hope for a trickle-up effect and the introduction of this kind of screen on other Apple computers. And please, with a larger bit depth and the ability to show the Adobe RGB color space. If Eizo can do it …
Then perhaps I don’t have to listen to my patients complaining about computer screen related eyestrain so often.
