Abstract
A display device includes at least one second splicing screen and at least two first splicing screens. The first splicing screen includes a first substrate, a first blue light-emitting unit disposed on the first substrate, and a first yellow fluorescent layer coated on the first blue light-emitting unit. The second splicing screen includes a second substrate and a plurality of second light-emitting units 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. 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 first splicing screens.
