Abstract: The present disclosure discloses a method for evaluating crosstalk in a naked-eye stereoscopic display, including: controlling a display panel to display sequentially viewpoint images; when displaying each of the viewpoint images, each of sub-pixels for displaying a current viewpoint image displays a white image, each of sub-pixels for displaying other viewpoint images displays a black image; obtaining sequentially, on a light emitting side of the display panel, first luminance values of light at respective test angles corresponding to the current viewpoint image; controlling the display panel to display an all-black image, obtaining sequentially second luminance values of light at the respective test angles; determining a crosstalk value of light at one test angle corresponding to any one of luminance peaks in the first luminance values, according to the one of luminance peaks and one second luminance value at the same test angle corresponding to the one of the luminance peaks.

Abstract translation: 本公开公开了一种用于评估裸眼立体显示器中的串扰的方法，包括：控制显示面板以顺序地显示视点图像; 当显示每个视点图像时，用于显示当前视点图像的每个子像素显示白色图像，用于显示其他视点图像的每个子像素显示黑色图像; 在所述显示面板的发光侧依次获得与所述当前视点图像对应的各测试角度的光的第一亮度值; 控制显示面板显示全黑图像，顺序地获得各个测试角度的第二亮度值; 根据与亮度峰值中的一个对应的相同测试角度的亮度峰值和一个第二亮度值之一，确定与第一亮度值中的任何一个亮度峰值对应的一个测试角度的光的串扰值。
