In this report, we demonstrated optoelectronic neuromorphic device to mimic the biological visual system. This artificial visual system was fabricated by monolithically integrating a photovoltaic divider and a synaptic transistor. The device showed synaptic functionalities such as short‐term plasticity (STP), long‐term potentiation (LTP), and neuromorphic facilitation with various light input range. Moreover, this artificial visual display system performed light‐adjustable perception behaviors such as photopic or scotopic adaptation.
