Patent ID: 8395841

Claim:
A reflective projection screen having multi-incident angles comprising: a plain screen surface having a smooth curved surface forming a reflection screen; said reflection screen configured to receive images from a short focal point projector in a manner such that the received images are reflected in a horizontal direction to a viewer, wherein said reflection screen has a height that is equally divided along the height of the reflection screen into a plurality of reflection surfaces, and each reflection surface of said plurality of reflection surfaces having a height between about 0.1 to 30 mm, and each reflection surface having a different inclined angle ranging from about 1 degree to about 45 degrees along said reflection screen, wherein each reflection surface is configured to reflect the received images from the short focal point projector in the horizontal direction towards the viewer, and wherein said different inclined angles of the reflection surfaces increases from a lower portion to an upper portion of the reflection screen in a way such that the plurality of reflection surfaces are connected to form the smooth curved surface of the reflection screen, and wherein each reflection surface is arrayed as an eccentric circle.
