High-luminance one-dimensional integral imaging display based on gradient-width line light sources

A high-luminance one-dimensional integral imaging display is presented in this paper. A gradient-width line light source array behind an elemental image array is proposed. The widths of the line light sources with equal pitches gradually increased from both sides to center. The viewing ranges generated by the line light sources were enlarged from both sides to the center. The light illuminating the left half of the elemental image array was superimposed on the right side, and the light illuminating the right half of the elemental image array was superimposed on the left side. The viewing zone was related to the leftmost and rightmost line light sources, and the luminance was improved by enlarging the other line light sources.
