A light source module and a method for manufacturing the same, and a backlight module and a display device using the same are provided. The method includes the following steps. A reference light source module is provided. The reference light source module comprises a substrate and plural light-emitting units arranged on the substrate. Then, plural optical trends between every two adjacent light-emitting units are obtained. Then, plural optical ratios between every two adjacent light-emitting units are calculated, in which each of the optical ratios is a ratio of each of the optical trends to a total reference optical trend of the reference light source module. Then, plural target distances are calculated according to the optical ratios and plural initial distances between every two adjacent light-emitting units are adjusted according to the target distances, thereby forming a target light source module.

Light source module and method for manufacturing the same, and backlight module and display device using the same

A light source module includes a back plate and light-emitting units. The back plate includes a bottom plate and a sidewall. An included angle is formed between an outer side surface of the sidewall and a horizontal plane where the bottom plate is located, and the included angle is an acute angle. An optical distance is defined between a top end of the sidewall and the horizontal plane. The light-emitting units are arranged in the back plate. The light-emitting units which are closest to the sidewall are defined as target light-emitting units, and each of the target light-emitting units has a radiation angle, and each of the target light-emitting units is separated from the sidewall by a distance. The first horizontal distance is determined by a tangent function of a complementary angle of the radiation angle, the second horizontal distance is determined by a tangent function of the included angle.
