Although Computex is the big trade show for IT related products in Taiwan, it’s far from the only show during the year and this week it’s Display Taiwan, a show that focuses on display panels and everything related. The show is a pure industry tradeshow and much of what’s on display has to do with the manufacturing of the actual panels, but a few companies were also displaying actual panels and some interesting technology that we’ll give you a closer look at over the next few pages, so click on in for some coverage from the show.
Although Chimei and AUO were absent from the show this year, Taiwan's third panel maker CPT or Chunghwa Picture Tubes was at the show and had a fair few things on display. First up the company was demoing a 10.1-inch USB 3.0 powered display and although it featured standard netbooks resolution of 1024×600 it was low power enough to be able to be powered by a single USB 3.0 port. On top of that CPT had added support for two point touch and there's even a USB 3.0 pass-through port, as the display wouldn't use up all the available bandwidth.
CPT was also showing off larger 18.5 and 21.5-inch USB 3.0 powered displays, although both of these models required two USB 3.0 ports to get enough power, something of a failure in terms of usability with most notebooks. On the upside we're looking at resolutions of 1366×768 and 1920×1080 which is vastly better than that of the 10.1-inch model. The brightness level on both of these displays was also close to that of regular desktop displays, something many USB displays have a problem with.
Next we have CPT's transparent 15.6-inch display which has a fairly impressive resolution of 1600×900 and this is a truly transparent display, not semi-transparent as most other larger transparent displays are. Have a look at the video below for an idea of how well it works. The demo consisted of a couple of small figurines behind the panel and various moving elements that reveal or hid the objects behind the panel.
CPT was also demoing a 2.18mm thin 3.5-inch phone display with qHD or 960×540 resolution and the company claims that this is one of the thinnest screens of this kind in the world. It's really quite hard to see how thin it is on the picture, but this is the kind if display that will help make smartphones even thinner than they are today.
The final model we're going to cover here is CPT's joint venture with Pixel Qi which was announced at Computex, but which we sadly missed then. The new screen is a 10.1-inch model with 1280×800 resolution and it's targeting Android tablets. The advantage of the Pixel Qi technology is that the backlight can be switched off while the screen remains readable, although colours suffer quite badly from it. The advantage is that you can extend the battery life of your device by a pretty good margin and it also makes it much easier to read the screen as it looks more like an eBook reader than a tablet, which in our opinion is a good thing when reading text.
