More than a year ago I wrote a post all about a technique that can offer real colour to ereaders, colour that would work no matter how bright the ambient lighting is, and is fast enough to compete with LCD screens as well. Well this miraculous technique is called electrowetting, and it seems that it is nearing production on a sensible scale finally.
As you can see from the short video here, the colour it offers is as bright and rich enough as one could wish, the refresh rate (how quickly it can change screens) is fast enough to show videos in full colour and generally it is apparently the best thing since the invention of the sliced loaf. Further, as with e-Ink displays, it works perfectly well in bright sunlight, unlike LCD screens that fade away to blackness in bright light.
As with e-Ink screens, electrowetting is not a form of back lit computer screen, but more like paper in that it reflects light that falls on it, and not using light that shines through it from behind… Front lit, rather than back lit in other words.
When you add all the above qualities to the fact that it has the same sort of battery drain as a normal monochrome ereader using e-Ink, then you realise we are looking at a serious contender to become the screen technology that all digital devices with any sort of display can use (Tablets, digital watches, ereaders, laptops and so on). One of the main problems with iPads and their ilk is the very short battery endurance they have, partly owing to the heavy drain on them caused by their screens continually refreshing themselves.
