Brightness adjusting method, device and equipment

The invention discloses a brightness adjustment method, device and equipment, and the method comprises the steps: determining a first brightness level driving signal in response to an obtained first brightness level adjustment instruction; when it is determined that output of a current brightness level driving signal is ended, the first brightness level driving signal is output to adjust the screen brightness to a first brightness level, the first brightness level driving signal has a first duty ratio, the current brightness level driving signal has a second duty ratio, and the first duty ratio is different from the second duty ratio. 本申请公开了一种亮度调整方法、装置和设备，所述方法包括：响应于获取到第一亮度级调整指令，确定第一亮度级驱动信号；确定当前亮度级驱动信号输出结束，输出所述第一亮度级驱动信号以调整屏幕亮度到第一亮度级，其中所述第一亮度级驱动信号具有第一占空比，所述当前亮度级驱动信号具有第二占空比，所述第一占空比与所述第二占空比不同。
