Abstract:
An image projection apparatus. The image projection apparatus comprises a light source and LCD panel. The LCD panel comprises a plurality of pixels and color filters thereon. Light from the light source is projected to the pixels along an irradiative path and the LCD panel selectively reflects the projected light in accordance with an image signal along a projective path, wherein an angle between the irradiative and projective paths exceeds 0°.
