The Apple iPad Isn't Going to Revolutionize the Display Industry

The iPad's old-tech LCD screen demonstrates, once again, that the perfect display is at least 10 years away

2 min read

The iPad, Apple’s much-anticipated tablet computer due out this month, isn’t going to revolutionize the display industry. It doesn’t sport a bright organic LED display. It isn’t even wearing the latest Pixel Qi technology, which combines LCD technology with a black-and-white reflective version for easy viewing in bright sunlight.

The iPad uses a simple full-color LCD, backlit with LEDs, the kind of display you see today on many flat-screen televisions and computer monitors. Apple’s decision to go with the LCD isn’t particularly surprising. The iPad will be used to display photos and videos, and to do that it needs a full-color, full-motion display. So E Ink and its monochrome brethren are out. OLED technology is just too expensive right now, and Pixel Qi is a compromise—it gives up a bit in color saturation to pick up that visibility in sunlight.

Why Functional Programming Should Be the Future of Software Development

It’s hard to learn, but your code will produce fewer nasty surprises

You’d expectthe longest and most costly phase in the lifecycle of a software product to be the initial development of the system, when all those great features are first imagined and then created. In fact, the hardest part comes later, during the maintenance phase. That’s when programmers pay the price for the shortcuts they took during development.

So why did they take shortcuts? Maybe they didn’t realize that they were cutting any corners. Only when their code was deployed and exercised by a lot of users did its hidden flaws come to light. And maybe the developers were rushed. Time-to-market pressures would almost guarantee that their software will contain more bugs than it would otherwise.
