An image display apparatus according to one embodiment of the present disclosure includes: an output section that outputs projection light along a predetermined axis; an irradiated member to be irradiated with the projection light; and a first optical member that is disposed downstream of the irradiated member on a light path of the projection light, and reflects or diffuses a portion of the projection light that has transmitted through the irradiated member.

A three-dimensional (3D) display system may include a peg array of multiple pegs. Each peg may be individually addressable and designed to move along one or more axes. The 3D display system may also include an induction array having multiple electromagnetic coils to generate electromagnetic fields. The electromagnetic fields may induce magnetic forces upon at least one peg to cause the peg to move along an axis into an actuated position. The 3D display may also include a display screen to be distended into a 3D topography via contact with at least one peg in the actuated position.

A lighting system for air mobility may include a light emitting unit provided on a boom or a propeller of the air mobility and configured to emit light toward a ground surface so that the light is projected onto a point directed toward the ground surface from the propeller or the boom; and a control unit electrically connected to the light emitting unit and configured to control light emitting modes of the light, emitted by the light emitting unit, based on operating modes of the air mobility or operating modes of the propeller.

A portable billboard is presented including a portable media projection subsystem to selectively project media and to supply an enablement signal in response to the media being projected. A location device supplies a geographic location of the media projection subsystem. A verifier receives the enablement signal and the geographic location, and supplies verification information responsive to the media being projected from a stationary location for a predetermined minimum duration of time. A communications subsystem receives verification information and either stores the information for subsequent downloads, or transmits the information to a central controlling server. A targeting subsystem permits an entity to select a target stationary location from a plurality of value weighted target stationary locations. The targeting application typically provides a reward in response to a value of the selected target stationary location.

Disclosed herein are a plurality of laser sources forming an element. Multiple laser elements are arranged in a pattern to form an array. Each laser element of the array is independently addressable, such that video and other content can be projected from the array.
