A subpixel area-based evaluation method for an improved slanted lenticular film that minimizes the crosstalk in a quasi-three-dimensional (Q3D) display is proposed in this paper. To identify an optimal slant angle of the film, a subpixel area-based measurement is derived to evaluate the crosstalk among viewing regions of the intended subpixel and adjacent unintended subpixel by taking the real subpixel shape and black matrix into consideration. The subpixel mapping, which corresponds to the optimal slant angle of the film, can then be determined. Meanwhile, the viewing zone characteristics are analyzed to balance the light intensity in both right and left eye channels. A compact and portable Q3D system has been built and appropriate experiments have been applied. The results indicate that significant improvements in both crosstalk and resolution can be obtained with the proposed technique.
本文提出了一种基于子像素区域的评估方法，用于改进倾斜柱面透镜膜，以最小化准三维（Q3D）显示器中的串扰。为了确定该膜的最佳倾斜角度，通过考虑实际子像素形状和黑矩阵，推导出一种基于子像素区域的测量方法，以评估目标子像素和相邻非目标子像素的观看区域之间的串扰。然后可以确定与该膜的最佳倾斜角度相对应的子像素映射。同时，分析观看区特性以平衡左右眼通道中的光强度。构建了一个紧凑便携的Q3D系统并进行了适当的实验。结果表明，所提出的技术可以在串扰和分辨率方面取得显著改进。
