Claim of US Patent No. 10,338,875

1. A reflective display comprising:two adjacent reflective bodies being positioned side-by-side and spaced apart by a gap and each one of the two adjacent reflective bodies comprising a front reflective surface for displaying a stream of images thereon; and
a seam inserted in the gap between the two adjacent reflective bodies, the seam comprising:
a strip of light propagating material, the strip of light propagating material defining a front surface, two sides surfaces and a back surface, the side surfaces being positioned between the adjacent reflective bodies and the front surface of the strip of light propagating material being aligned with the front reflective surfaces of the adjacent reflective bodies;
a plurality of lighting units positioned along the back surface of the strip of light propagating material for propagating light in the strip of light propagating material towards the front surface of the strip of light propagating material, whereby when light is propagated in the strip of light propagating material, the gap between the two adjacent reflective bodies is visually suppressed; and
a plurality of light detectors, the light detectors being positioned along the strip of light propagating material, each light detector for collecting light projected on the reflective surfaces in an area surrounding the light detector and generating corresponding lighting data,
wherein each lighting unit comprises: a red light-emitting diode (LED), a green LED and a blue LED, and each lighting unit further comprises a light controller for controlling actuation of the red LED, the green LED and the blue LED.
