| description | The invention provides a brightness control method and a brightness control circuit of an outdoor display screen and a display device.In the brightness control method of the outdoor display screen, when a battery is in a discharging state, the SOH value, the SOC value and the battery temperature of the battery and corresponding preset attenuation coefficients are obtained; and determining a brightness attenuation coefficient based on the SOH value and the SOC value of the battery and the preset attenuation coefficient corresponding to the battery temperature, outputting a corresponding brightness adjustment signal, and adjusting the display brightness of the outdoor display screen to the preset brightness, so that when the battery is abnormal, the power and the brightness of the outdoor display screen are correspondingly reduced, and the display time is prolonged.
本发明提出一种户外显示屏的亮度控制方法及亮度控制电路、显示装置，其中，户外显示屏的亮度控制方法中，在电池处于放电状态时，获取电池的SOH值、SOC值和电池温度以及各自对应的预设衰减系数，并基于电池的SOH值、SOC值和电池温度对应的预设衰减系数确定亮度衰减系数，以及输出对应的亮度调节信号，调节 |
