1. A light source module, comprising:
a substrate configured to have a plurality of light-emitting regions arranged in an array manner, wherein each of the light-emitting regions of the substrate is provided with two light-emitting groups, each of the light-emitting groups comprises a plurality of light-emitting branches arranged side by side, and two driving chips are disposed in parallel between the two light-emitting groups; wherein the two driving chips are centrally symmetrically arranged; and
single-layer-layout wiring arranged on the substrate, wherein the single-layer-layout wiring couples the driving chips within each of the light-emitting regions to each other and electrically connects each of the driving chips to the light-emitting branches within one of the light-emitting groups; wherein each of the light-emitting branches comprises one sub-millimeter light-emitting diode, alternatively, each of the light-emitting branches comprises at least two sub-millimeter light-emitting diodes, wherein the at least two sub-millimeter light-emitting diodes are connected in parallel or in series.
