Abstract: A display module and a method for monitoring backlight brightness are provided in the present disclosure. The display module includes a display region including an opening region and a non-opening region. The display module includes a backlight module and an array substrate. The array substrate is at a light-exiting side of the backlight module. The array substrate includes a plurality of gate lines which extends along a first direction and is arranged along a second direction, and further includes a plurality of data signal lines which is arranged along the first direction and extends along the second direction. The array substrate further includes a first substrate and at least one photosensitive unit, where the photosensitive unit is at a side of the first substrate away from the backlight module; and the photosensitive unit is disposed at the non-opening region for sensing a luminous brightness of the backlight module.
