Abstract: A head mounted display including a frame wearable on a user's head, first and second imaging apparatuses integrating on the frame and at least one control unit. Each imaging apparatus includes a display unit having a plurality of pixels arranged in matrix. The control unit is utilized for selectively setting a part of the pixels as display pixels and the rest of the pixels as non-display pixels, thereby determining the positions of display areas on the display units. Two virtual images respectively seen by a user can be adjusted to substantially coincide with each other by scrolling the positions of the display areas on the display units. The present invention also provides an image adjustment method for the head mounted display.

Abstract: The present invention relates to an illumination device of an LCD projection system. The illumination device comprises a light source, a quarter-wave retardation and a wire grid polarizer. The light source is used for providing light. The quarter-wave retardation is disposed near the light source. The wire grid polarizer is disposed parallel to the quarter-wave retardation, and is associated with the quarter-wave retardation to polarize the light from the light source. P-polarized light can pass through the wire grid polarizer. S-polarized light cannot pass through the wire grid polarizer, and is reflected to the quarter-wave retardation to become circular polarized light. The circular polarized light is reflected by a parabolic surface of the light source and passes through the quarter-wave retardation again to convert into p-polarized light. The converted p-polarized light can pass through the wire grid polarizer.
