We propose a new type of an electronic re-writable blackboard that keeps the trace of finger-drawn strokes using the bitmap of scatting light from segmental membrane. Images can be erased entirely or partially by releasing voltage or pulling back the membrane with magnetic force, respectively. Thanks to the simplicity of the device structure and principle, the proposed display has scalability to an oversized board that could be made by printing or embossing.
