Pixel Qi claims it can beat iPad display

LONDON – Pixel Qi Corp. (San Bruno, Calif.), a developer of reflective liquid crystal displays that can be read in sunlight thereby saving power, has announced that it can produce a screen with higher image quality than the iPad 3 retina screen. The company said it is in discussions to finalize partners and customers for the technology and the screen sizes they need.
The two drawbacks currently faced by the Pixel Qi LCD technology are that when it is backlit and in full color the contrast and saturation are not as good as conventional LCD technology and when it goes into reflective mode it drops back to monochrome display.
However, CEO Mary Lou Jepsen said on the company's website that: "We have a new architecture that matches the resolution of the iPad 3 screen and its full image quality, including matching or exceeding contrast, color saturation, the viewing angle and so forth with massive power savings."
At the same 2048 by 1536 resolution Pixel Qi claims that its display will consume about 1 watt compared with the iPad 3 display's 8 watts (see table below).

Jepsen added that there is an additional very low power mode that consumes just 1 percent of the power consumed by the iPad 3 screen.
However, no indication was given of when the improved Pixel Qi screens would be forthcoming or any photographs provided of the next generation Pixel Qi displays.
Before founding Pixel Qi in 2008 Jepsen was CTO of the One Laptop Per Child (OLPC) organization.
Pixel Qi, founded in 2008, is included in version 13.0 of the Silicon 60 list of emerging startups published by EE Times. Pixel Qi entered the Silicon 60, EE Times' list of emerging startup companies at version 11.0 in October 2010.

To extend the time of use per charge, tablet vendors would welcome a better power saving display technology. Yet, consumers are demanding high quality display, e.g. iPad retina display. In addition, if users are using their tablet device primarily on watching video, a better display will serve the purpose better. On the contrary, if I am reading online content or ebook most of the time, I will demand a power saving tablet. What would you choose between power saving and better display?

Yes it is truly said even though the display is not confirming the standards at present, it can be surely used in environments where power consumptions comes in mission critical factor. It might take time to be used in graphics oriented devices but in industrial environment it can surely be adopted.

Looks like more vapor ware to this grizzled veteran. As Jerry Maguire almost surely would have said "SHOW ME" the (display)!

Some interesting claims here, but why isn't comparison price listed? Without that, it is difficult (read pretty much impossible) to make any valid comparison or decision if you are a design engineer.

Not convinced enough with the claims. Also the drawbacks are not small to be ignored. The price and the battery life in different modes can give a better picture of the claims.

Interesting - I would have preferred they just do it. You do not win this game by talking . Show me the gizmo and we will make the call.

Quite an interesting claim but they still have problems with the implementation.

Not sure why they haven't yet built prototype to prove their claims. Its better to build prototype to test the claims rather than just hype about it.
