Full grayscale subjective consistency optical data obtaining method and splicing display panel

A full grayscale subjective consistency optical data obtaining method, configured to obtain optical data applied to an initial splicing display panel, wherein the initial splicing display panel comprises a first display panel and a second display panel spliced together, the first display panel comprises a liquid crystal display panel, the second display panel is different from the first display panel in type, and the method comprises:

• obtaining a plurality of bonding point colors, sets of reference bonding point optical parameters of the first display panel corresponding to the bonding point colors and sets of bonding point optical parameters of the second display panel corresponding to the bonding point colors, wherein a display image of the second display panel under effect of each set of the bonding point optical parameters is subjectively consistent with a display image of the first display panel under a corresponding set of the reference bonding point optical parameters;
• determining non-bonding point optical parameters of the second display panel corresponding to non-bonding point colors between adjacent two of the bonding point colors according to the bonding point colors, the sets of the reference bonding point optical parameters, and the sets of the bonding point optical parameters;
• and
• determining the optical data according to a correspondence between the bonding point colors and the sets of the bonding point optical parameters and according to a correspondence between the non-bonding point colors and the sets of the non-bonding point optical parameters.
