Color moire reduction and resolution enhancement of flat-panel integral three-dimensional display

Color moire occurs owing to the subpixel structure of the display panel in the integral three-dimensional (3D) display method, deteriorating the 3D-image quality. To address this, we propose a method for reducing the color moire and improving the 3D-image resolution, simultaneously, by combining multiple 3D images. In the prototype system, triple 3D display units with lens arrays closely attached to 8K-resolution display panels arc optically combined. By controlling the color moire of the 3D image generated on each display and shifting and combining the elemental lenses constituting the lens array, sufficient reduction in the color moire is realized, while suppressing the deterioration of the 3D-image quality, at a distant position from the lens array in the depth direction, along with an approximately two-fold enhancement of the resolution near the lens array.
