TWO COMPANIES have in a team effort pried away the ultimate eye-candy trophy from the grasp of Steve Jobs and his Ipad 2 by demonstrating a 10.1in WQXGA 2560x1600 resolution RGBW display at the SID Display conference in Los Angeles.
While simply saying that the technology, which goes by the name of "PenTile RGBW", is equivalent to having a 10.1-inch 300 dpi colour print in your hands, that just wouldn't be enough. However if we blurt outright that the pixel density is more than twice that of Apple's Ipad 2 display, then you'll get a real idea of what this means.
The "W" in RGBW stands for white, as it was through the addition of a fourth component colour that the firms have been able to increase the pixel density so much. The side benefit of this is that it also reduces the number of transistors needed in a panel array by half, which in turn also halves power consumption. Of course, being that LCDs suck quite a lot away from a mobile device's battery life, halving the power consumption of an LCD is tantamount to extending the battery life by about 10 per cent, which is quite an accomplishment.
There are, however, other upsides to this. This is a technology that puts touchscreen resolutions up to desktop display levels. The RGBW display has twice the transmittance of a regular touchscreen and will easily double the brightness of current devices. The 300cd per square metre brightness can go as high as 600cd in outdoor mode. Contrast figures have not been given.
Samsung has a lead here and is taking care of bunging these displays into its devices. By the end of the year, which is Samsung's predicted commercial availability, we should have 2560x1600 Samsung Tab III's running amok in the market. Let's just hope the graphics hardware can keep up.
So, Nouvoyance developed it, and Samsung is marketing it. But it's not an exclusive. Companies like Wacom and others might want to crack open their piggy banks and spring for access to some of this display technology. µ
