Abstract

The lenticular grating is the most widely adopted core light control device in the naked-eye autostereoscopic display technology, which has a certain inclination angle with the subpixels on the liquid crystal display to eliminate the moirefringes. However, the segmentation of the sub-pixels by the edge of the lenticular lens unit will inevitably lead to the sawtooth of the displayed three-dimensional image. Therefore, a weighted optimization algorithm for synthetic images is proposed in this paper, which is based on the sub-pixel segmentation area and adjacent pixel values for correction. In the experiment, the sawtooth of the reconstructed image is suppressed and the display quality is improved.
