具体地，高导金属件330指的是具有高电流易熔断特性的金属件。高导金属件330可根据高电流熔断特性，在输入高导金属件330的电流超过熔断电流阈值时，会自动产生熔断。
进一步的，基于高导金属件330连接在子像素驱动单元322与子像素发光单元312的阳极之间，进而在子像素驱动单元322输出的电流大于熔断电流阈值时，高导金属件330自动断开，使得子像素驱动单元322与子像素发光单元312的阳极之间连接通路断开，防止异常亮点，消除异常亮点影响。
上述的的像素电路的实施例中，通过在子像素发光单元的阳极与子像素驱动单元之间的连接处设置能够在高电流下熔断的高导金属件，进而在子像素发光单元发生亮点异常时，即子像素发光单元输出电流大于熔断电流阈值时，熔断单元会自动熔断，对亮点异常进行自动修复，极大的缩短了异常亮点的修复时长。通过在子像素发光单元的阳极与子像素驱动单元之间的连接处设置高导金属件，相当于在像素电路中增加一道光罩，由于面板内的亮点内电流较大，将该高导金属件自动熔断，使得子像素发光单元的阳极与子像素驱动单元之间断开，消除亮点影响，实现了像素亮点自修复，提高了显示效果，提高了面板生产效率。

具体地，当发光单元410包括三个子像素发光单元412；像素驱动单元420包括三个子像素驱动单元422时，熔断单元430的个数为三个，则各子像素驱动单元422与子像素发光单元412的阳极一一对应连接，各子像素驱动单元422与各子像素发光单元412的阳极之间一一对应连接各熔断单元430。进而可分别对三个子像素发光单元412进行异常亮点自修复。实现在发光单元410包含的任意一个子像素发光单元412发生亮点异常时，即该子像素发光单元412输出电流大于熔断电流阈值时，相应的熔断单元430会自动熔断，对亮点异常进行自动修复，极大的缩短了异常亮点的修复时长，提高了显示效果，提高面板生产效率。

其中，发光单元510包括红色像素发光单元512，绿色像素发光单元514和蓝色像素发光单元516；像素驱动单元520包括三个子像素驱动单元522；各子像素驱动单元522分别与红色像素发光单元512，绿色像素发光单元514、蓝色像素发光单元516的阳极一一对应连接；红色像素发光单元512与相应的子像素驱动单元522之间连接有熔断单元530；绿色像素发光单元514与相应的子像素驱动单元522之间连接有熔断单元530；蓝色像素发光单元516与相应的子像素驱动单元522之间连接有熔断单元530。
