ABSTRACT:
A writeboard according to an embodiment of the invention includes plural display cells capable of controlling light within a visible-light spectrum, the display cells being arranged over a display surface of the writeboard. The writeboard also typically includes plural memory cells coupled with the display cells, and plural first receivers arranged with the display cells and the memory cells over the display surface. The first receivers typically are configured to receive transmitted writing information and to communicate the transmitted writing information to corresponding memory cells for storage. Corresponding display cells thus may be selectively activated in accordance with the transmitted writing information.
