Abstract
This paper describes operating characterization of MEMS blackboard type display which is proposed and confirmed the actuation by Roi Shigematsu in 2006. This display is 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. Pixels of this display consisted of square line type but we propose new type pixels, square dot type and hexagonal line type pixels and evaluate by measuring hysteresis.
