The invention relates to the technical field of backlight source structures, and particularly relates to an integrated backlight source structure having a high-precision backlight source. The integrated backlight source structure includes a back frame, a backlight source consisting of arrangement of a plurality of light-emitting sources and arranged in the back frame, a light guiding plate arranged on one side of the backlight source, a diffusion plate arranged on the light-emitting plate, a filter arranged between the light guiding plate and the backlight source; a photoeffect enhancement medium is arranged on one side incident upon the backlight source, of the light guiding plate; a first reflective film is arranged on one side opposite to the backlight source, of the light guiding plate; a second reflective film is arranged on one side opposite to the diffusion plate, of the light guiding plate; a reflective surface of the first reflective film faces the backlight source, and a reflective surface of the second reflective film faces the diffusion plate; the diffusion plate includes a light-incoming surface and a light-outgoing surface; and a plurality of semicircles which are successively arranged are jointed to form the light-outgoing surface of the diffusion plate. The integrated backlight source structure can achieve a good condensation effect of light entering the light guiding plate, and has a high-precision backlight source.
