Abstract: The present disclosure proposes an overcurrent protective circuit and a display panel. The overcurrent protective circuit includes a power supply circuit, a logic algorithm circuit, and an overcurrent protective circuit. The logic algorithm circuit is additionally arranged in the overcurrent protective circuit. The logic algorithm circuit set different threshold currents of overcurrent protection for the display panel according on different driving frequencies. The overcurrent protective circuit adjusts the protective components inside the overcurrent protective circuit in accordance with the set threshold currents. Therefore, the display panel is protected by the overcurrent protective circuit at different frequencies.
