Abstract
本公开涉及显示技术领域,提出一种显示面板及其驱动方法、显示装置。该驱动方法包括:在第一显示亮度值,向显示面板输入占空比为X的脉宽调制信号,同时控制子像素单元的发光驱动电流为M,X和M通过第一调试规则获取,X>0,M>0;在第二显示亮度值,向显示面板输入占空比为Y1的脉宽调制信号,同时控制子像素单元的发光驱动电流为N1,第一显示亮度值大于第二显示亮度值,Y1>0,N1>0;其中,当第二显示亮度值对应的占空比和发光驱动电流通过第一调试规则获取时,第二显示亮度值对应的占空比为Y2,第二显示亮度值对应的发光驱动电流为N2,Y2>0,N2>0且Y1小于Y2,N1大于N2。该驱动方法可以提高低显示亮度值阶段的显示效果。
