LED display screen power supply control method and device, electronic equipment and medium

The invention relates to the field of power supply control, in particular to an LED display screen power supply control method and device, electronic equipment and a medium. The method comprises the steps of obtaining a plurality of images; determining a similarity rate between two adjacent images based on the plurality of images; and judging whether the similarity rate of the adjacent images is higher than a preset similarity rate threshold, if so, generating a power reduction instruction, and controlling the power supply controller to reduce the output power. The method has the effect of reducing electric energy waste. 本申请涉及电源控制的领域，尤其是涉及一种LED显示屏电源控制方法、装置、电子设备及介质。方法包括：获取多张图像；基于多张图像，确定相邻两图像之间的相似率；判断相邻图像的相似率是否高于预设相似率阈值，若是，则生成功率降低指令，并控制电源控制器降低输出功率。本申请具有减少电能浪费的效果。
