Abstract: The working principle of piezoelectric ceramic displays was described in this paper. Utilizing the inverse piezoelectric effect, the piezoelectric ceramic display takes piezoelectric actuator as its pixel driving source. The preparation processes of piezoelectric ceramics were introduced and the available ceramic materials for display were analyzed. Finally, key technologies restricting the development of ceramic displays were discussed.
