图4所示的相关的像素电路在工作时,NG(N)可以控制数据线D1上的数据电压Vdata是否写入驱动晶体管M3的栅极。
在具体实施时,可以通过NG(N)提供的第一扫描信号以控制打开第一个第二晶体管或关断第一个第二晶体管,以控制数据线上的数据电压是否写入驱动晶体管的栅极,从而控制是否对本行像素电路的亮度进行更新;当NG(N)输出高电压信号时,第一个第二晶体管打开,可以对本行像素电路的亮度进行更新;当NG(N)输出低电压信号时,第一个第二晶体管始终关闭,数据线上的数据电压的变化不会写入驱动晶体管的栅极,有机发光二极管的发光亮度不会变化,即当前行像素电路在当前帧的显示亮度维持不变。综上可知,可以通过控制N型晶体管的打开或关闭,即可实现像素亮度的刷新,因此当想实现部分像素不刷新时,保证N型晶体管关闭即可。
