  • Publication number: 20080297734
    Abstract: A projection display device and a method for controlling off-beams thereof are provided. The projection display device includes a case, a light source which is disposed in the case and outputs color light, a digital micro mirror device (DMD) which is disposed in the case, and controls micro mirrors and reflects the color light received from the light source, thereby outputting on-beams and off-beams, and an output unit which is disposed in the case and allows the off-beams output from the DMD to be projected to the outside of the case. Accordingly, the off-beams output from the DMD are output to the outer case through a shutter, prism, color filter, or an integral lens, so that a color of the outer case can be adjusted and also an exterior of the projection display device can be brightened.

  • Publication number: 20080158522
    Abstract: A laser projector which controls power to a plurality of light sources and a method thereof are provided. The laser projector includes a plurality of light sources, a sensing unit, a power supply unit which supplies power to each of the light sources, and a control unit which adjusts the power supplied to the light sources, based on a sensing result of the sensing unit. Since the power supplied to the light sources is controlled based on the result of sensing at least one of a motion of an object and a slope of the projector, a user is protected from a laser beam emitted from the laser projector.

  • Publication number: 20060215124
    Abstract: An image projection apparatus adjusting a whit balance in consideration of temperatures and light levels of LEDs and a white balance adjustment method thereof. The image projection apparatus comprises a light source unit sequentially emitting lights generated by a red (R)-light emitting element, a green (G)-light emitting element, and a blue (B)-light emitting element. Light levels of the R-light emitting element, the G-light emitting element and the B-light emitting element change depending on changes in temperature. An image generation unit generates an image using the lights sequentially emitted from the light source unit and projects the image. A driving unit drives the light source unit and the image generation unit. A temperature sensor measures a temperature of the light source unit. A light sensor measures levels of light generated by the R-light emitting element, the G-light emitting element, and the B-light emitting element.
