Abstract
Disclosed is an LED module assembly for a display including a first LED module and a second LED module. The first LED module includes a first unit substrate, a plurality of LED chips mounted on the first unit substrate to form a plurality of pixels, and a first light absorbing layer formed on the first unit substrate. The second LED module includes a second unit substrate, a plurality of LED chips mounted on the second unit substrate to form a plurality of pixels, and a second light absorbing layer formed on the second unit substrate. The first unit substrate and the second unit substrate are laterally connected to each other. Each of the first light absorbing layer and the second light absorbing layer includes a plurality of valleys formed between the plurality of pixels. The first light absorbing layer includes a first inclined portion formed obliquely from the upper end edge of the interface between the first unit substrate and the second unit substrate to the upper portion of the side surface of each of the outer LED chips mounted on the first unit substrate. The second light absorbing layer includes a second inclined portion formed obliquely from the upper end edge of the inte…
