Mary Lou Jepsen, Inventor of Pixel Qi Technology, Discusses Screen Technologies & Multi-touch Tablets

I've been meaning to devote a few more posts about the new screen technologies as multi-purpose netbooks become available.  In my opinion, this technology will change the way we access all sorts of interactive media, including news and entertainment.

In this post, I feature Mary Lou Jepsen, an engineer who is the inventor of Pixel Qi technology. During the first quarter of 2010, there is a possibility that a few Pixel Qi screens will become available to the DIY community.  The first units will be multi-touch. Pixel Qi will be at the January CES in Las Vegas.

Mary Lou has worked on the screen technology found in One Laptop per Child (OLPC) project, and her work has resulted in affordable net-books and laptops.  According to information from the Pixel Qi website, "Mary Lou founded Pixel Qi Corporation in 2008 and is its CEO.  Previously, Mary Lou has founded 4 companies, served as a professor at RMIT (Australia) & MIT,  and in executive management at Intel Corporation.  Mary Lou holds a Ph.D. in Optical Sciences, a B.S. in Electrical Engineering and a B.A. in Art (req.) all from Brown University as well as a Master of Science (in Holography) from the MIT Media Lab.".

Mary Lou Jepsen, an engineer,  tests out "e-paper" content in the sunlight and in the shade on three screens. In the following video, the E-ink Amazon Kindle, an Acer Pixel Qi 3Qi LCD netbook, and a Toshiba transflexive R600 laptop are compared.  At 4:20, Jepsen discusses touch and remarks that there are new touch technologies that might work. (The content on the resistive touch screen that was on hand during the video was difficult to see.)

Mary Lou Jepson demonstrates the Pixel Qi screen in her home lab/laundry room on the OLPC (One Laptop Per Child). Jepson is focused on making screens that everyone can use.

Pixel Qi is working on a design of a sub-10 watt HDTV that can run on a minimal power supply, including a battery that can be charged with a crank or solar pane.
