A portable projector is disclosed. The portable projector comprises a light transmission member having first and second surfaces, a multi-type laser light source including a plurality of sub laser light sources for emitting light beams onto the first surface of the member based on an external image signal, so as to allow the light beams to be transmitted into the member, one or more optical elements supported on at least one of the first and second surfaces of the member for diffracting and reflecting the light beams incident from the multi-type laser light source into the member, and at least one multi-type scan mirror supported on one of the first and second surfaces of the member for scanning the light beams diffracted and reflected from the optical elements onto an external screen located at the outside of the member, based on an external control signal.

Portable projector

A laser display device, which eliminates speckles generated in the transmission of laser beams and uniformly mixes laser beams of various colors, and an optical coupler therefor. The laser display device includes light sources emitting laser beams; an image display unit displaying an image by the laser beams; and a speckle elimination unit located on a path of the laser beams, and including at least one panel having an uneven part and disposed on an optical axis of the light sources.

Laser display device and optical coupler therefor

A back light unit is disclosed. The back light unit includes a laser light source having a superior system organization efficiency and color reproducibility, and achieves uniform illumination by diffusing laser beams onto a light guide panel.

Back light unit

An external mounting type head up display device for a vehicle, which can be mounted irrespective of kind of vehicle, is disclosed. The head up display device includes a display unit to convert a signal into an image and output the image, an optical element decentered with respect to an optical axis of the display unit, the optical element magnifying the image and transmitting the image, and a combiner provided in front of a driver to provide the driver with the transmitted magnified image.

Head up display device

The present invention relates to a high speed direct mold clamping apparatus. The direct mold clamping apparatus has a grooved channel for the flow of oil inside a clamping cylinder to minimize the flow of oil between inside and outside the clamping cylinder. Then, the clamping ram can perform high speed reciprocation in the clamping cylinder.

High speed direct mold clamping apparatus of an injection molding machine

Disclosed is an injection unit having a rotatable device for preventing reverse flow. To connect first flow channels formed in a spacer and second flow channels formed in a screw head when the metering is performed, and prevent reverse flow of resin by cutting off the first flow channels and the second flow channels when the resin is injected, the injection unit has a torsion spring as spring means between a shaft of the screw head and a screw, thereby rapidly preventing movement of the melted resin by restoring force of the spring when the metering of the resin is finished.
