An unmanned aerial system (UAS) that displays an image, video or other effect is described. The UAS may include a camera that captures the image for display. The UAS may be used in connection with a water display, and multiple UASs may operate together.

This disclosure relates to an automotive glass display. An example vehicle includes a projector configured to project light, and a glass panel including a first layer of glass, a second layer of glass, a first layer of polyvinyl butyral (PVB), and a second layer of material. The first layer of PVB is configured to diffuse light from the projector, and the second layer of material is configured to reduce glare. Other example glass panel arrangements are also disclosed.

Screen vibration systems are provided that can vibrate theatre screens using acoustical, electromagnetic, or another type of energy while reducing the presence of image artifacts that may otherwise be visible as result of vibrating the screen. In one example of a screen vibration system, the system includes a screen, a permanent magnet mounted to the screen, and a magnetic source positioned with respect to the permanent magnet and uncoupled from the screen. The screen is moveable in response to a changing magnetic field from the magnetic source.

A screen can be vibrated by vibrators that are drivable by signals. Each vibrator can be adjacent in position to other vibrators that are drivable by different types of drive signals than a drive signal associated with the vibrator. The number of drive signals can be equal to or less than the number of vibrators. A vibrator assembly for a vibrator can include a baffle and a transducer that couples to the baffle. The transducer can vibrate at least a portion of the screen. The vibrating screen can be monitored by a sensor and an analyzer unit that can analyze image speckle and screen displacement artifacts in captured images of images projected onto the screen and output results of the analysis.

Screen vibration systems are provided that can vibrate theatre screens while reducing the presence of image artifacts that may otherwise be visible as result of vibrating the screen. In one example of a screen vibration system, the system includes a screen, a permanent magnet mounted to the screen, and a magnetic source positioned with respect to the permanent magnet. The screen is moveable in response to a changing magnetic field from the magnetic source.

A screen device includes a screen, a plurality of first photoelectric conversion elements, a plurality of second photoelectric conversion elements, a flying object, a support member, and a controller. The plurality of first photoelectric conversion elements are on the screen and are arranged at an outermost periphery, in a frame shape, of an area in which photoelectric conversion elements are arranged. The plurality of second photoelectric conversion elements are on the screen and are arranged inside the area at the outermost periphery covered by the plurality of first photoelectric conversion elements. The flying object is configured to be powered by electric power generated by the plurality of second photoelectric conversion elements. The support member connects the screen with the flying object. The controller is configured to control the flying object based on an evaluation of the electric power generated by the plurality of first photoelectric conversion elements.

To provide a display device that makes speckles on a screen difficult to be visually recognized and allows an observer to easily observe an image projected on the screen easily. A display device includes a projector that emits coherent light, a screen that projects the coherent light emitted from the projector, and a first optical system that guides transmitted light or diffused light of the screen to an observing direction of an observer, and allows an observer to observe a real image or a virtual image of an image projected on the screen. The screen includes a plurality of particles including a first portion and a second portion, a particle layer having a plurality of particles, electrodes for applying a voltage to the particle layer to generate an electric field for driving the particles of the particle layer.

Provided is an optical sheet which includes a plurality of particles and can sustain a speckle reduction effect over long periods of time, and which is used in a screen that is capable of displaying an image by being irradiated with light, the optical sheet including a particle layer having an insulating liquid, a holding layer, and a plurality of particles held rotatably in the holding layer. The particles include a first portion and a second portion, and are held in the holding layer so that the insulating liquid is present around the particles. The kinetic viscosity at 25 C. of the insulating liquid is 5.5 mm.sup.2/s or less.

A display system includes a projector configured to project image light and a reflector including a gripper and a reflection surface over which a reflective material having light scattering capability is uniformly disposed.

A speckle damping system for dampening speckle on a projection screen for a projection display system employing coherent or partially coherent light sources (e.g., lasers, LEDs) are disclosed. In one embodiment, a rotatably coupled system is disclosed, comprising: a set of actuators; a set of rotatably coupled mounts, each of said set of rotatably coupled mount capable of mounting at least one said actuator; and wherein said at least one actuator mounted on said rotatably coupled mount is in moveable mechanical communication with said projection screen. In another embodiment, a linearly coupled system is disclosed comprising: a set of actuators; a set of linearly coupled mounts, each of said set of linearly coupled mount capable of mounting at least one said actuator; and wherein said at least one actuator mounted on said linearly coupled mount is in moveable mechanical communication with said projection screen.
