1. A front light source module, configured to be arranged on a display side of a reflective display, the front light source module comprising: a light guide plate and an edge-lit light source; wherein
a light exit surface of the light source faces a side of the light guide plate; and
a plurality of dots and a plurality of release coatings in one-to-one correspondence to the plurality of dots are disposed on a first surface of the light guide plate, and an orthographic projection of the release coating on a second surface of the light guide plate is overlapped with an orthographic projection of the dot corresponding to the release coating on the second surface of the light guide plate;
wherein the first surface and the second surface are two planar surfaces of the light guide plate opposite to each other, and in the case that the front light source module is disposed on the display side of the reflective display, the second surface of the light guide plate is closer to the reflective display relative to the first surface of the light guide plate.
