A head-up display device includes an imaging device configured to emit light to generate a plurality of virtual images, a first mirror configured to reflect the light of the imaging device, and a second mirror unit configured to reflect the light reflected from the first mirror unit to a windshield. The second mirror unit includes a mirror assembly including a concave mirror and a plate coupled to the concave mirror, a tilt mechanism coupled to the plate and being configured to tilt the plate and the concave mirror, a plurality of bonding portions provided between the plate and the concave mirror to bond the plate and the concave mirror.

Head-up display device

A mems scanner package and a scanning projector including the same are disclosed. The MEMS scanner package includes a MEMS scanner including a mirror surface for reflecting light, a magnet disposed behind the MEMS scanner, a lower case having an accommodation space formed therein to accommodate the magnet, an upper case having an opening formed therein to pass light, reflected from the MEMS scanner, therethrough, and a transparent cover unit for covering the opening. The transparent cover unit is embodied as a transparent member, and is coupled to the upper case while being inclined at a predetermined inclination angle with respect to the MEMS scanner.

An image projection image for projecting an image on a screen includes a light source, a scanning mirror and a prism. The light source includes laser diodes for emitting beams of different wavelengths. The scanning mirror reflects the beams radiated from the light source and projects the reflected beams. The prism is disposed at the rear of the scanning mirror to decenter the beams via the scanning mirror based on the wavelengths. In the image projection apparatus, the laser diodes are fixed to be vertically spaced apart from a reference height, corresponding to the wavelengths of the beams.

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

There is disclosed a laser projection display including a light source unit for emitting light laser light; a light resolution unit for resolving the laser light into a first light and a second light; an optical scanner for realizing an image by scanning the resolved first light to a screen; a sensing unit for sensing the resolved second light; and an alignment compensation unit for calculating location variation of the second light sensed by the sensing unit and compensating color alignment to correspond to the calculated location variation value, wherein a distance between a light emitting surface of the light resolution and a light incidence surface of the optical scanner is equal to a distance between a light emitting surface of the light resolution unit and a light incidence surface of the sensing unit.
