Provided is a compact projection display with high throughput. The projection display includes: an illumination unit which irradiates a plurality of single color light beams; a first scanner scanning the plurality of light beams irradiated from the illumination unit along a first direction; a light modulator with a linear array of micro-electromechanical system (MEMS) devices that are arranged parallel to the first direction; an F-&#x3b8; lens disposed between the first scanner and the light modulator and having a first entrance pupil and a second entrance pupil; and a second scanner disposed opposite to the second entrance pupil of the F-&#x3b8; lens and which scans a light beam passing through the second entrance pupil of the F-&#x3b8; lens on a screen along a second direction that is orthogonal to the first direction.

Projection display for displaying a color image by modulating a plurality of single beams according to image information

A compact rear projection display which can be used in mobile devices is provided. The compact rear projection display includes a main body unit which generates image signals, an image providing unit which forms and projects an image according to the image signals received from the main body unit, a transparent light guide plate, and a screen disposed at a surface of the transparent light guide plate. The transparent light guide plate guides the image incident from the image providing unit to be displayed on the screen.

Compact rear projection display

A slim optical projection system and an image display apparatus employing the same. The optical projection system includes: a relay lens group to produce an intermediate image from an image created by a display and to generate a first distortion in the intermediate image, a projection lens group to enlarge and project the intermediate image that passes through the relay lens group and to generate a second distortion in the projected image, and a reflector to reflect the image enlarged by the projection lens group to a screen at a wide viewing angle. The first and second distortions are used to compensate for a third distortion caused by the reflector.

Slim optical projection system and image display apparatus employing the same

A projection display system includes a screen, an illumination projecting system to form an image using light radiated by a light source, to magnify the image, and to project the image along a rear side of the screen, and a reflection unit having an array of unit mirrors to reflect the image received from the illumination projecting system onto the screen, each of the unit mirrors having a first sloped reflection surface and a second reflection surface adjacent to the first reflection surface having a predetermined angle therebetween.
