[0035] Specifically, the original visual angle difference coefficients of each box are normalized as follows: the original visual angle difference coefficients of all light points of a single box are normalized respectively. After the original visual angle difference coefficients of the plurality of boxes are normalized, the normalized original visual angle difference coefficients of the plurality of boxes are collected to obtain a set of original visual angle difference coefficients. After the plurality of boxes are spliced, the overall visual angle difference coefficients of each light point in the sub-display are normalized, and the normalized overall visual angle difference coefficients are collected to obtain a set of overall visual angle difference coefficients.
