PURPOSE: An artificial high resolution retina stimulator is provided to prevent damage to cells due to heat generation. CONSTITUTION: An artificial high resolution retina stimulator comprises a main circuit unit which receives signal-processed video information and converts the information into an electric signal, and a supplementary circuit unit which receives the information of the main circuit and stimulates a retina electrode with direct electric signal. One or more supplementary circuit unit shares the main circuit unit. In the supplementary circuit unit, a decoder and a microelectrode array are integrally formed.
