Abstract

A micro light-emitting display module includes sequentially stacked a substrate, a light-emitting chips, an original sealant layer, and a repair sealant layer, the original sealant layer is located in a first display area and a second display area, and the repair sealant layer is located in the first display area, A mass proportion of optical particles in the repair sealant layer is different from that of optical particles in the original sealant layer, and/or, the types of the optical particles in the repair sealant layer is different from that of the optical particles in the original sealing layer. By optimizing the types and the mass proportion of the optical particles in the repair sealant layer, the color difference between the repaired first display area and the normal second display area could be made close.
