A scanning projector and a method for operating a scanning projector including a light source module including a plurality of color light sources including at least one color light source provided in a plurality, and a scanner configured to execute scanning in the horizontal direction and the vertical direction using light beams emitted from the light source module. Light beams emitted from the plurality of same color light sources are projected on different positions on a screen within one frame and, thus, more rapid and effective scanning may be executed and a high-quality image may be formed.

Scanning projector and method for operating a scanning projector

A display device according to embodiments of the present disclosure includes a determination unit to determine a display mode, a light generator to selectively irradiate a 2D light or a hologram 3D light, a spatial light modulator to selectively display a 2D image or a hologram 3D image, and a control unit that controls the light generator to selectively irradiate the 2D light or the hologram 3D light and controls the spatial light modulator to modulate the 2D light or the hologram 3D light irradiated from the light generator to display the 2D image or the hologram 3D image according to the display mode determined by the determination unit.

Display device and operating method thereof

There is disclosed a screen including a first diffusion plate for transmitting a laser light for image display, a second diffusion plate spaced apart a preset distance from the first diffusion plate, and a plurality of optical transmission tubes arranged between the first diffusion plate and the second diffusion plate to transfer the laser light transmitted from the first diffusion plate to the second diffusion plate, wherein the optical transmission tube includes a body portion comprising a first surface facing the first diffusion plate and a second surface facing the second diffusion plate, vided in the body portion to a central region of the second surface provided in the body portion, and at least one optical fiber arranged in the through hole to transfer the laser light, only to reduce speckle noise of laser, and a laser display apparatus using the same.
