Abstract: Transparent displays enable many usefiil applications, including heads-up displays for cars and aircraft as well as displays on eyeglasses and glass windows. Unfortunately, transparent displays made of organic light-emitting diodes are typically expensive and opaque. Heads-up displays often require fixed light sources and have limited viewing angles. And transparent displays that use frequency conversion are typically energy inefficient. Conversely, the present transparent displays operate by scattering visible light from resonant nanoparticles with narrowband scattering cross sections and small absorption cross sections. More specifically, projecting an image onto a transparent screen doped with nanoparticles that selectively scatter light at the image wavelength(s) yields an image on the screen visible to an observer. Because the nanoparticles scatter light at only certain wavelengths, the screen is practically transparent under ambient light. Exemplary transparent scattering displays can be simple, inexpensive, scalable to large sizes, viewable over wide angular ranges, energy efficient, and transparent simultaneously.

Abstract: An apparatus includes an array of lasers, an array of electrical drivers, and an optical filter. Each laser is configured to produce light in a corresponding wavelength-channel, wherein the wavelength-channels of different ones of the lasers are different. The electrical drivers are connected to directly modulate the lasers. Each driver produces a first driving current or voltage to cause a corresponding one of the lasers to be in a first lasing state and produces a different second driving current or voltage to cause the corresponding one of the lasers to be in a different second lasing state. The optical filter is connected to receive light output by the lasers. The optical filter selectively attenuates light from each of the lasers in the first lasing states thereof and to selectively pass light from each of the lasers in the second lasing states thereof.

Abstract: A high brightness color selective light modulator (CSLM) (10) formed by a polarization modulator (100) positioned between two retarder stacks (110, 120). The modulator (100) changes the apparent orientation of one retarder stack to the other, in a first switching state of the modulator, the two retarder stacks (110, 120) cooperate in filtering the spectrum of input light, and in a second switching state the two retarder stacks (110, 120) complement each other, yielding a neutral transmission spectrum. Two or more CLSM stages (1420-1430) can be used in series for providing independent control of a primary color. One embodiment eliminates internal polarizers between CLSM stages, thereby providing an additive common-path full-color display with only two neutral polarizers (1450, 1460). Hybrid filters (2225) utilize the CSLMs (1420-1430), in combination with other active or passive filters. The CSLMs (1420-1430) can be arranged in a multi-pixel array (2230), and can be implemented as color filter arrays, using patterned passive retarder instead active polarization modulators.
