Claim 0:
1. A splicing display device, comprising:
at least two first splicing screens, wherein each of the at least two first splicing screens comprises a first substrate and a plurality of first light-emitting units, the plurality of first light-emitting units are disposed on the first substrate, and each of the plurality of first light-emitting units comprises a first blue light-emitting unit and a first yellow fluorescent layer coated on the first blue light-emitting unit; and
at least one second splicing screen, wherein each of the at least one second splicing screen is sandwiched between adjacent two of the at least two first splicing screens, the at least one second splicing screen comprises a second substrate, a plurality of second light-emitting units are disposed on the second substrate, at least a part of the plurality of second light-emitting units is second blue light-emitting units, color-gamut adjusting units are disposed on at least a part of the second blue light-emitting units, and a light-emitting spectrum of the second blue light-emitting units through the color-gamut adjusting units is consistent to a light-emitting spectrum of the at least two first splicing screens,
wherein the at least two first splicing screens are liquid crystal display screens, the at least one second splicing screen is a mini light-emitting display (MLED) screen, the color-gamut adjusting units comprise a second fluorescent layer and a color resist layer, the second fluorescent layer is disposed on the at least a part of the second blue light-emitting units, and the color resist layer is disposed on the second fluorescent layer.
