Particle Screen Patents
We helped MindFlow obtain multiple patents directed to novel displays that use particles to create images on a screen. The patented inventions, described in U.S. Patents Nos. 9,122,143 and 9,690,091 ("Dynamically Variable Graphic Material Using Electrostatically Attracted Particles"), offer power efficiency advantages over prior art displays, and enable new forms of one-way displays that can be placed in or over windows to display an advertisement to viewers outside without blocking the view out the window.
