Description of the Invention: [Technical Field of the Invention] The present invention is directed to a flexible screen of a flexible front projection type and a sinusoidal image. Feng Tong Contrast, 咼 [Prior Art] The application of the front projector is shorter with the light projection technology of the optical projection technology. It is not only energy-consuming but also the main purpose of the projector. The ultimate goal of the projector is to image Heavy screen # is an important factor in determining image quality.

The front projection screen of the glass is a white glory to reflect light, or to use the glory on the glass. The role of the glass beads is to reflect the full range of light, so the brightness is higher than that of the white screen. The ηίΐ is the same as the vertical viewing angle, and the light efficiency is low. In the conventional first two scenes, when the viewing angle is increased, the brightness becomes low, and when the brightness is increased, the viewing angle is changed, and the glass beads are diffused (diffused reflecti〇n). Interfering with the light emitted by the projector makes the contrast of the image worse. 13.01926 US3^;si〇f2 ^ ^ „ SF=,=d?
