Backlit erasable writing board
摘要:
A backlit erasable writing board includes a light guide panel, a plurality of light emitting diodes positioned on at least one side surface of the light guide panel for providing light to the light guide panel, a reflecting plate at a back surface of the light guide panel for reflecting light toward a front surface of the light guide panel, and an impervious translucent film at the front surface of the light guide panel for use as an erasable writing surface.
