Patent number: 8253914Abstract: A liquid crystal display (LCD) is provided that comprises a rearward LCD substrate sheet that has an array of vias formed, where the vias provide electrical conduction between both sides of the rearward LCD substrate sheet. The number of vias in the array is substantially equal to or at least equivalent to a combination of a number of column drive lines and a number of row drive lines. The respective drive lines are connected to a corresponding via, such as on one side of the rearward LCD substrate sheet, and respective patterned conductors are connected to a corresponding via, such as on the other side of the rearward LCD substrate sheet. The patterned conductors provide a connection between respective drive lines and one or more corresponding drivers. In one example, this allows a “full bleed” display to be generated.Type: GrantFiled: June 23, 2010Date of Patent: August 28, 2012Assignee: Microsoft CorporationInventors: James T. Kajiya, John Turner Whitted

Publication number: 20120044565Abstract: A delay line interferometer is configured with a liquid-crystal (LC) tuning element as a phase modulator for demodulating a phase-modulated input signal. The LC tuning element allows for quickly tuning the phase difference between two optical signals separated from the phase-modulated input signal, so that the two optical signals can be coherently recombined to interfere with each other and produce one or more intensity-modulated optical signals. In some embodiments, the LC tuning element is configured to reduce polarization-dependent frequency shift without the use of additional high-precision optical elements and/or coatings.Type: ApplicationFiled: August 20, 2010Publication date: February 23, 2012Inventors: Ruibo Wang, Ruipeng Sun
