Abstract
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.
Claims22
A rear projection display comprising:
- 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;
- and
- a transparent light guide plate, and a screen formed at a side thereof, wherein the image received from the image providing unit is guided to the screen by the transparent light guide plate,
- the transparent light guide plate comprising a transparent image incidence surface through which the image projected by the image providing unit is incident, and a magnifying reflection surface facing the transparent image incidence surface and, which magnifies and reflects the image incident through the transparent image incidence surface,
- wherein the magnifying reflection surface is convex.
A rear projection display comprising:
- a main body unit which generates image signals;
- an image providing unit , which forms an image according to the image signals received from the main body unit;
- and
- a flat transparent light guide plate,
- wherein the transparent light guide plate comprises:
- a screen disposed at a surface of the transparent light guide plate,
- a transparent image incidence surface, disposed at a first end of the transparent light guide plate, through which the image projected by the image providing unit is incident;
- a first reflection surface, facing the transparent image incidence surface at the first end of the transparent light guide plate, which reflects the image incident through the transparent image incidence surface;
- a second reflection surface, facing the first reflecting surface and disposed at a second end of the transparent light guide plate, which reflects the image reflected by the first reflection surface;
- and
- a mirror array, facing the screen, which reflects the image reflected by the second reflection surface to the screen, whereby the image is incident on the screen at a right angle thereto.
