Method and device for weight optimization of multi-layer liquid crystal near-eye display based on visual system characteristics

Abstract

The invention discloses a multilayered liquid crystal display weight optimization device based on visual system characteristics. The multilayered liquid crystal display weight optimization device comprises a spatial light modulator array, a polarizing film array, backlighting equipment, and a control terminal, which are sequentially arranged in the human eye sight direction, wherein the spatial light modulator array is used for modulating transmittance of polarized light accessing the human eyes; the polarizing film array is used for modulating the bias light accessing the spatial light modulator array to be the polarized light; the backlighting equipment is used for providing backlight with uniform luminance to the spatial light modulator array; the control terminal is used for controlling the transmittance of RGB (Red, Green and Blue) channels of each pixel on the spatial light modulator array, so as to realize near-eye three-dimensional display. The invention further discloses a multilayered liquid crystal display weight optimization method based on the visual system characteristics. The method comprises the following steps: putting forward that the central area and the marginal area of a reconstructed light field possess different weight ranges, meanwhile combining with focused convergence conflict resolution conditions, computing the final weight angle, and enabling the optimization result to be closer to the truth. The multilayered liquid crystal display weight optimization device based on the visual system characteristics and the multilayered liquid crystal display weight optimization method based on the visual system characteristics disclosed by the invention obviously increase the optimization speed, and enhance the real-time performance of the optimization algorithm.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display, in particular to a method and device for optimizing the weight of multi-layer liquid crystal near-eye display based on the characteristics of a visual system. Background technique [0002] Three-dimensional display technology has received more and more attention in the field of display, and the development of this technology has affected every aspect of human life. From the vigorous development of 3D movies, to the global popularity of Google Glass, to Oculus acquired by Facebook for 2 billion US dollars, all have shown the world the broad development prospects of 3D display. The reason is that the 3D display provides the depth information that the traditional 2D display does not have, bringing users an excellent visual experience. But because of this, the biggest problem in 3D display is how to provide enough information to achieve 3D display effect with high spatial resolutio...
