Pixel Qi have been demonstrating the latest version of their 3qi display at Computex 2010, complete with its wider viewing angles, and going by jkkmobile's reaction the new screen is a success. As with previous versions, the new panel has indoor/outdoor functionality including a backlight-off mode for prolonging battery life, but it's also much easier to see from the side judging by Pixel Qi's demo prototypes.
Update: Added demo video of Pixel Qi's new tablet reference design after the cut.

There are also some new touchscreen demo devices and a couple of tablets on show, though the exact touchscreen technology Pixel Qi are using isn't clear. There's already a projected capacitance panel on sale, but they've promised other touchscreen systems too. No sign of the Notion Ink Adam, one of the best known - and most hotly anticipated - tablets to use the 3qi display.
High volume production for the new, wide-angle screen is expected to kick off this fall, though Pixel Qi still aren't saying exactly who will be adopting them for their products.
