REAR-PROJECTION SCREEN FOR HIGH DEFINITION SIGNAL DISPLAY |
摘要 |
<p>A rear-projection screen for high definition signal display includes a lens layer and a screen display layer. The lens layer is Fresnel lens layer (10); the screen display layer includes a lens (11), a black grating (11), a light scattering plate (13), and a transparent protecting layer (15). One side of the lens (11), which is faced Fresnel lens (10), is a plurality of vertical semicolumn surface, and another side is flat surface; the black grating (12),which is a plurality of parallel black stripes, is provided on the flat surface of the lens (11); the light scattering plate(13)contains optical microtube, the light entering surface of thelight scattering plate (13) is connect with the side having black grating of the lens (11)by using a transparent layer; the transparent protecting layer (15) is coated on the light exiting surface of the light scattering plate (13).</p> |
