Abstract
A light source module includes a power transmission substrate and a plurality of point light sources. The power transmission substrate has a plurality of dimming areas disposed along a first direction. The point light sources are spaced apart from each other in each dimming area along the first direction and receive driving power applied to each dimming area through the power transmission substrate and generate light. A spatial interval between the point light sources in the first direction is greater in dimming areas more distant from the center of the power transmission substrate than in dimming areas closer to the center of the power transmission substrate.
