1. A spliced reflective display comprising:
a plurality of display devices, wherein each of the display devices is joined side to side with an adjacent display device such that the joined sides form an adjacent joint;
a front light guide plate disposed above the plurality of display devices and proximate to a display side, the front light guide plate having a top surface near the display side and including an optical structure; and
at least one light source located at a side of the front light guide plate, wherein the light source emits light into the front light guide plate;
wherein the light from the light source is reflected from the top surface of the front light guide plate to the plurality of display devices, and subsequently, light reflected from the plurality of display devices forms image light directed toward the display side to display an image, wherein the optical structure guides the path of the image light to shield the adjacent joint from being visible on the display side.
