Patent ID: 10129533

Abstract:
A three dimensional (3D) stereoscopic image rendering system uses a lenticular lens sheet with a light diffusing multi-layer, which may include an adhesive layer, formed on the external surface of its lower base. The microstructural constitution of the light diffusing multi-layer suppresses moiré patterns typically affecting the 3D images. When longitudinally directed stray light rays are internally reflected from the interior surfaces of each lenticular lens in the sheet and impinge on the light diffusing multi-layer contacting the lower base, the stray light rays are scattered diffusely into various directions, thereby significantly reducing the intensity of the moiré pattern and its effect on the image. In addition, certain related problems, such as crosstalk between left and right directed images are also reduced. As a result, the viewer perceives a high quality, moiré free, stereoscopic 3D image.
