Abstract
Embodiments of the present disclosure provide a method for correcting a micro polychrome light emitting device, including: obtaining a rotational compensation between a first display and a second display of the micro polychrome light emitting device, a first image rendered by the first display being rotatable according to the rotational compensation to align with a second image rendered by the second display; determining, based on the rotational compensation, a regional segmentation scheme and a shift compensation scheme for the first image; and correcting a rotational offset between the first display and the second display by segmenting the first image into regions based on the regional segmentation scheme and shifting each of the regions of the first image according to the shift compensation scheme.
