Abstract: A light source module according to some example embodiments includes a first substrate and a plurality of second substrates. The first substrate includes a plurality of connectors configured to at least receive a supply of electrical power and a plurality of first connection pads that are configured to be electrically connected to the plurality of connectors. The second substrates each include a plurality of mounting elements on an upper surface and a plurality of second connection pads on a lower surface of the second substrate and configured to be electrically connected to the plurality of mounting elements. Each mounting element may be connected to a separate light-emitting device. A plurality of connection members may electrically connect the first connection pads of the first substrate to the plurality of second connection pads of the plurality of second substrates.

Abstract: Provided are a light source module and a backlight unit (BLU) including the same. The light source module includes a substrate including a base plate extending in a first direction and a pair of dam structures stacked on opposing sides of the base plate along a second direction, orthogonal to the first direction, and extending along the base plate in the first direction, wherein the pair of dam structures are spaced apart from each other along a third direction, orthogonal to the first and second directions. A plurality of light-emitting devices are mounted on the substrate between the pair of dam structures and spaced apart from one another in the first direction. An encapsulation layer covers at least one side surface and a top surface of each of the plurality of light-emitting devices. A height of the pair of dam structures is greater than a height of the encapsulation layer.
