Pixel Qi says it has a tablet screen as good as iPad' Retina but uses far less power

Apr 24, 2012 by Bob Yirka report

(Phys.org) -- In a post on the company blog, Mary Lou Jepsen, founder and head of Pixel Qi, boasts that her company has developed a tablet screen with a resolution that is equal to the Retina display on the new iPad but achieves it using far less battery power. She claims that the screen also has more color saturation, better viewing angles and better contrast.

Little known privately held Pixel Qi (pronounced as Pixel Chi) is based in San Bruno California, and makes Liquid Crystal Displays (LCDs) for laptops, tablets and other devices that have the unique ability to use direct to help brighten the screen when used outdoors. Called transflective, such devices actually use less power outdoors, compared to iPads, which use more.

Jepson says the motivation for creating a device equal in quality to the but much less power hungry came from reports that the new iPad overheats as it draws up to eight of power at peak consumption, a figure that she says “shocked” her.

Thus far in its short history, Pixel Qi hasn’t made much of a dent in the consumer market; its screens appear in only about a dozen little known products, such as the ARM based Adam tablet. This new development is likely to change that, if the claims made by Jepson turn out to be true, of course.

Jepson includes a chart on the blog post, showing power consumption of tablets with Pixel Qi screens compared to both the old and new iPad. And of course, the Pixel Qi screens beat the iPad by a very wide margin. Unfortunately, most of the chart is based on estimates, and thus far, no one, including Jepson, has offered any proof of the claims made.

Jepson says the Pixel Qi screen also has a power save mode that is a 100x reduction in power from peak on the iPad. She adds that she’s not trying to knock Apple or its popular tablet, but would like the world to know that there is a better option available.

Also missing from the blog post is pricing for the new screen, though Jepson says the company is currently in negations with prospective partners that will apparently use the new screen in their device. If that turns out to be true, then it shouldn’t be long before everyone else will be able to verify what Jepson is claiming, and if that happens, perhaps then even Apple will come knocking.

Just hope it won't be sued six feet under by Apple.

Yet another article about a claim of a device with no evidence.

Or Samsung or any of about 3 dozen others. One of them will buy it and or bury it for the time when they have used up all the other products already in the design/manufacturing pipeline.

The thing is, the Pixel Qi display probably eats up just as much power as the Retina panel, because they both work the same way when viewed with the backlight on.

Which is what most people would do, because actually using the transreflective mode makes it look like a pocket calculator - if their previous models are of any indication. You lose contrast and the image turns pretty close to grayscale.

Is that picture real or simulation of what it would look like?

`Normal` transmissive LCD have a good contrast at dark. With outside light their contrast takes a hit. The more outside light the lesser contrast will be. Transflective LCD still use backlight but also reflect outside light back. This means they have `medium` performance at most conditions, in dark and in bright light. So typically they have less contrast in dark than transmissive LCD, but more in bright light.
