Embodiment Construction

[0032] Throughout the following description, details are set forth in order to provide those skilled in the art with a more thorough understanding of the present invention. However, well known elements may not have been shown or described in detail to avoid unnecessarily obscuring the disclosure. Accordingly, the specification and drawings are to be regarded in an illustrative rather than a restrictive sense.

[0033] Some embodiments of the invention provide a projection display that includes a main projector and a highlight projector. The main projector may have a relatively low peak brightness and may be used to project the full image. The brightness of the highlights in the image projected by the main projector is lower than expected. A specular projector can project concentrated light to enhance the light at the location of the specular, thereby significantly increasing the brightness of the specular.
