Abstract
A large-scale display device has a plurality of display units, a plurality of screens and a plurality of adhesive bands. The plurality of display units is arranged in a matrix, and Frensnel lens screen(s) and diffuser screen(s) are correspondingly overlaid on the display units. The adhesive bands are used to affix the screens to the plurality of display units, or affix the plurality of Fresnel lens screens to the plurality of display units, followed by disposing a large-area diffuser screen on the previous screens. The sizes of the gaps between adjacent display units and the dark stripe in the large-scale image are thus reduced, such that the aesthetic feeling of the large-scale image is enhanced.
