Patent number: 8098431Abstract: Various embodiments of the invention relate to methods and systems for generating the color white in displays created from interferometric modulators and more specifically, to the generation of the color white through the use of reflected light at two wavelengths. In one embodiment, a display device displays the color white. The color white is generated by reflecting light from two pluralities of interferometric modulator types. The first modulator type reflects colored light at a specific wavelength. The second modulator type reflects colored light selected to be at a wavelength complementary to the first. The combined light reflected from the two types appears white in the display.Type: GrantFiled: April 21, 2009Date of Patent: January 17, 2012Assignee: QUALCOMM MEMS Technologies, Inc.Inventor: Philip D.

Patent number: 7843410Abstract: One embodiment includes a display of interferometric modulators having a configurable resolution characteristic. Selected rows and/or columns are interconnected via a switch. The switch can include a fuse, antifuse, transistor, and the like. Depending on a desired resolution for a display, the switches can be placed in an “open” or “closed” state. Advantageously, using the switches, a display can readily be configured for differing modes of resolution.
