Abstract
A light source module includes a driving substrate, a plurality of light source blocks and a currents control element. The light source blocks are disposed on the driving substrate, and each of the light source blocks includes at least one light source. The currents control element is disposed on the driving substrate, and has channel terminals for individually controlling driving currents passed through at least two light source blocks. The channel terminals are electrically connected to the at least two light source blocks, respectively. The currents control element is disposed on the driving substrate and individually controls the driving currents applied to the light source blocks, so that a number of wires of a connection cable connected to a light source driving connector is less than the number of light source drive currents being individually controlled.
