Abstract
A method for compensating display of a spliced screen, including: obtaining a picture to be displayed; obtaining a theoretical brightness gain of at least one sub-display region in a plurality of sub-display regions; obtaining an actual brightness gain of the central region according to the theoretical brightness gain of at least part of the sub-display regions, and obtaining actual brightness gains of a plurality of first nodes in the non-central region according to the theoretical brightness gain of at least part of the sub-display regions; obtaining an actual brightness gain of at least part of the non-central region by using a bilinear interpolation method according to the actual brightness gains of the plurality of first nodes and an actual brightness gain of at least one second node on the central region; and compensating the picture to be displayed based on an actual brightness gain of the picture to be displayed.
