Abstract

A array substrate includes: a first sub-pixel, a second sub-pixel and a dummy sub-pixel that are located in a display region; a luminance attenuation degree of the first sub-pixel is greater than that of the second sub-pixel along a target direction; and a light-emitting layer of the dummy sub-pixel is configured to emit light having a color the same as that of light emitted by the first sub-pixel. As the dummy sub-pixel further includes the connecting electrode electrically connecting the pixel circuit with the light-emitting layer of the dummy sub-pixel the luminance attenuation of the first sub-pixel may be effectively compensated by driving the dummy sub-pixel to emit light.
