Abstract: A system for reducing glare in a vehicle includes a windshield treated with a coating, an external light sensor configured to detect a position of a light source external to a vehicle, an eye sensor configured to detect a location of an eye of an operator of the vehicle. The system also includes an emitter configured to excite a location of the coating on the windshield from a first state to a second state that is more opaque than the first state. The system further includes a processor programmed to determine the location of the coating for exciting based on the detected position of the light source and detected position of the eye, and to control the emitter to selectively excite the coating at the location from the first state to the second state.

Abstract: An optical element includes a first boundary layer and a second boundary layer. A solution is disposed between the first boundary layer and the second boundary layer. The solution includes liquid crystals co-mingled with oblong photochromic dye molecules. The photochromic dye molecules are matched to the liquid crystals to offset a decrease in absorption of the photochromic dye molecules in response to a temperature increase of the photochromic dye molecules.

Abstract: Some OLED devices contain circular polarizers, which are used to reduce reflection from metallic electrodes. A novel OLED display module incorporates a photo-switchable polarizer that transitions between an active polarizing state and an inactive transmissive state, and further contains at least one optical sensor disposed in the OLED display module and adapted to measure light transmitted through the photo-switchable polarizer, and a controller configured to adjust a luminance of the organic electroluminescent layer based on the measured light transmitted through the photo-switchable polarizer.

Abstract: Disclosed are embodiments of photo-luminescent display systems and photo-luminescent visual elements creating eye-catching displays of visual advertising or marketing messages that are very effective at generating interest, engagement, and loyalty in the viewing public. Photo-luminescent pigment containing visual elements are illuminated by one or more remotely located emitters at a first wavelength that is outside the human visual spectrum. In response, the visual elements then radiate at one or more wavelengths within the human visual spectrum. Additional features control unwanted reflections and unwanted transmission of radiation at the first wavelength. Additional features control the uniformity of radiation of one or more wavelengths within the human visual spectrum.
