Abstract
An autonomous vehicle includes a window having first and second layers of polymer material between inner and outer layers of glass. The first layer of polymer material includes perovskite crystals that are activated by UV light and emit visible light. The second layer of polymer material is disposed between the outer layer of glass and the first layer of polymer material. The second layer of polymer material blocks UV sunlight to prevent activation of the perovskite crystals. The vehicle further includes a projector that is configured to project UV light onto the inside of the window to form illuminated images on the window.
Claims20
An autonomous vehicle comprising:
- a body having a cabin;
- a window including inner and outer layers of glass on an inside and an outside, respectively, of the window, the window further including:
- 1) a first layer of polymer material between the inner and outer layers of glass, at least a portion of the first layer of polymer material including perovskite nanocrystals that are activated by UV light in the range of 340 nm-380 nm, and emit visible light having a wavelength in the range of 450 nm-750 nm, and:
- 2) a second layer of polymer material between the outer layer of glass and the first layer of polymer material, wherein at least a portion of the second layer of polymer material blocks UV light having a wavelength of 400 nm or less to prevent activation of the perovskite nanocrystals by UV sunlight that is incident on the outer layer of glass;
- and
- a projector mounted in the cabin, wherein the projector is configured to project UV light having a wavelength in the range of 340 nm-380 nm onto the inside of the window to selectively activate the perovskite crystals and form illuminated images on the window that are visible from inside the cabin.
A vehicle comprising:
- a body having a cabin;
- a window including inner and outer layers of glass on an inside and an outside, respectively, of the window, the window further including:
- 1) a first layer of polymer material between the inner and outer layers of glass, at least a portion of the first layer of polymer material including perovskite crystals that are activated by UV light having first, second, and third wavelengths, and emit blue, green, and red visible light, respectively, and:
- 2) a second layer of polymer material between the outer layer of glass and the first layer of polymer material wherein at least a portion of the second layer of polymer material blocks UV light having a wavelength of 400 nm or less to prevent activation of the perovskite crystals by UV light from sunlight that is incident on the outer layer of glass;
- and
- a projector mounted in the cabin, wherein the projector is configured to project UV light having the first, second, and third wavelengths onto the inside of the window to selectively activate the perovskite crystals and form an illuminated image on the window that is visible from inside the cabin, wherein portions of the illuminated image are formed by blue, green, and red light emitted by the perovskite crystals.
A method of providing an illuminated image on a window of a vehicle, the method comprising:
- providing the vehicle with a window including inner and outer layers of glass on an inside and an outside, respectively, of the window, the window further including:
- 1) a first layer of polymer material between the inner and outer layers of glass, the first layer of polymer material including perovskite crystals that are activated by UV light and emit visible light, and:
- 2) a second layer of polymer material between the outer layer of glass and the first layer of polymer material, wherein the second layer of polymer material blocks UV light from sunlight that is incident on the outer layer of glass whereby the perovskite crystals do not emit light due to sunlight that is incident on the outer layer of glass;
- and
- utilizing a projector mounted in the cabin to project light having a wavelength in the range of 340 nm-380 nm onto the inside of the window to activate the perovskite crystals and form an illuminated image on the window that is visible from inside the cabin.
