Publication number: 20090277056Abstract: Microfluidic pixels are utilized to produce large format displays (billboards) that are both digitally controllable and are light weight. Each microfluidic pixel includes a wall having a front (display) surface, and a microfluidic system including a reservoir disposed behind the wall, a colorant fluid, a transparent display chamber disposed in front of the wall, a conduit, and a two-way pump. In the absence of colorant fluid in display chamber, the pixel has a background appearance determined by the color (e.g., white) of the front wall surface. The pump receives a digital control signal from a digital control circuit to transfer colorant fluid from the reservoir to the display chamber by way of the conduit, whereby the pixel's appearance changes to a “colored” appearance determined by the color and amount of the colorant fluid in the display chamber.Type: ApplicationFiled: May 8, 2008Publication date: November 12, 2009Applicant: Palo Alto Research Center IncorporatedInventors: Eric Peeters, Scott A.
