Micro-spacing LED display screen module based on RGB split array

The invention relates to a small-spacing LED display screen module based on an RGB split array, and belongs to the technical field of LED display screens. The light sources are R, G and B high-power single-color LED lamp beads, and light emitted by the light sources passes through the corresponding light valve arrays and then is projected to the rear panel. The light valve array can control the output intensity of a light path, and the light valve array is divided into three spatially independent areas corresponding to the three single-color LED lamp beads R, G and B respectively; each output pixel point on the front panel is connected with three sub-pixel points R, G and B on the rear panel by using an optical fiber bundle formed by three optical fibers to transmit light; the control panel is used for controlling the single-color LED lamp beads and the light valve array; and a lampshade for uniformly gathering light to the input surface of the light valve array is arranged between the light source and the li
