1. A method for evaluating a viewpoint density, comprising:
acquiring a quantity of viewpoints of a display panel;
comparing a size of an image spot radius of each viewpoint and image point spacing between the viewpoint and an adjacent viewpoint, and selecting one viewpoint as a reference viewpoint, calculating a crosstalk value between another viewpoint except the reference viewpoint and the reference viewpoint; and
evaluating a viewpoint density for auto-stereoscopic display according to comparison of the size of the image spot radius of each viewpoint and the image point spacing between the viewpoint and the adjacent viewpoint and the calculated crosstalk value between the another viewpoint and the reference viewpoint.
