Abstract
A spliced reflective display includes multiple display devices, a front light guide plate, and at least one light source. Among the multiple display devices, one display device is joined side-by-side with another to form an adjacent joint. The front light guide plate is affixed above the multiple display devices and is close to the display side. It has a top surface near the display side and includes an optical structure. The at least one light source is positioned at the side of the front light guide plate, and light therefrom reflects off the top surface of the front light guide plate onto the multiple display devices, and the reflected light from the display devices forms image light that is directed towards the display side to produce an image. The optical structure directs the path of the image light to obscure the adjacent joint from being visible on the display side.
