A low-crosstalk 3D display without color moiré patterns based on color light source array is proposed. The proposed 3D display consists of a color light source array, a transparent liquid crystal display (T-LCD) panel, a scattering layer, and a parallax barrier from back to front. The color light source array consists of three primary color light sources that correspond to the sub-pixels on the T-LCD panel. These light sources project the sub-pixels with matching color to the same location on the scattering layer to form new pixels without color moiré patterns. The new pixels have inter-pixel gaps that enhance signal bandwidth and decrease crosstalk. The parallax barrier projects the new pixels of parallax images to different viewpoints, creating a 3D effect. A prototype is developed and evaluated.
