Abstract
A light source module includes: a substrate; and a plurality of light emitting devices having different ranks and arranged on the substrate in columns and rows, the plurality of light emitting devices being classified in the different ranks based on at least one of color coordinates, brightness of light emitted therefrom and a driving voltage, wherein in at least one of the columns and rows, light emitting devices having different ranks from among the plurality of light emitting devices are alternated in a basic arrangement and are alternated in an inverse arrangement opposite to the basic arrangement.

A light source module comprising:
- a substrate;
- and
- a plurality of light emitting devices having different ranks and arranged on the substrate in columns and rows, the plurality of light emitting devices being classified in the different ranks based on at least one of color coordinates, brightness of light emitted therefrom and a driving voltage,
- wherein in at least one of the columns and the rows, light emitting devices having different ranks from among the plurality of light emitting devices are alternated in a basic arrangement and are alternated in an inverse arrangement opposite to the basic arrangement,
- wherein both light emitting devices disposed at ends of each of the columns and the rows having the basic arrangement and the inverse arrangement have a same rank, and both light emitting devices disposed in a center of each of the columns and the rows have a same rank, and the rank of both light emitting devices disposed in a center of each of the columns and the rows is different from the rank of both light emitting devices disposed at the ends of each of the columns and the rows, and
- wherein the number of light emitting devices having a rank and the number of light emitting devices having a rank different therefrom are the same in each of the columns and the rows.
