Method, system, device and equipment for adjusting peak brightness of display panel

The invention relates to a method, a system, a device and equipment for adjusting peak brightness of a display panel. The method comprises the following steps: acquiring the actual peak brightness of the display panel; determining a peak brightness difference according to the actual peak brightness and the target peak brightness of the display panel; determining a compensation voltage according to the peak brightness difference and a preset first gamma curve of the display panel; and adjusting the power supply voltage of the display panel according to the compensation voltage so as to adjust the peak brightness of the display panel. Therefore, the peak brightness of the display panel can be improved, and the requirements of users are met. 本申请涉及一种显示面板峰值亮度调节方法、系统、装置、设备。该方法包括：获取显示面板实际峰值亮度；根据显示面板的实际峰值亮度和目标峰值亮度，确定峰值亮度差；根据峰值亮度差和显示面板预置的第一伽马曲线，确定补偿电压；以及根据补偿电压对显示面板的供电电压进行调节，以调节显示面板的峰值亮度。从而能够提高显示面板的峰值亮度，达到用户的需求。
