Design of Fresnel lens for autostereoscopic 3D display with optimized crosstalk and brightness uniformity

Abstract

At present, the naked-eye three-dimensional (3D) display technology still has some drawbacks, such as low brightness uniformity, high crosstalk, low light efficiency, short viewing distance, and the manufacturing is difficulty. Based on the principle of naked-eye 3D display and the Fresnel optical theory, this paper designs a Fresnel lens array and the star-shaped liquid crystal display (LCD) switch of unit LCD screen to achieve low-crosstalk and high brightness uniformity for the autostereoscopic 3D display. The unit parameters of a 139.7 cm 4K model autostereoscopic 3D displayer are provided and they are optimized by the TracePro software. The results show that when the pitch of the Fresnel lens on the exit surface is 0.304 mm, the width of each serration of Fresnel lens is 0.023 4 mm, the length of the Fresnel lens is 2.87 mm, and the center height of star-shaped LCD switch is 0.030 mm, the center length is 0.040 mm, the width of star-shaped LCD switch is 0.050 mm, and the image crosstalk is less than 2% when the viewing distance is 2.50 m. The problem on the brightness of the image in different positions is improved.
