Abstract: A display panel and a display device are provided in the present disclosure. The display panel includes a substrate and an array layer on the substrate, where the array layer includes a plurality of control units, one control unit includes a plurality of thin-film transistors, and the plurality of thin-film transistors in a same control unit is sequentially arranged along a ring-shaped path. The display panel further includes a plurality of light-emitting units on a side of the array layer away from the substrate. The plurality of light-emitting units and the plurality of control units are in a one-to-one correspondence. A light-emitting unit includes a plurality of light-emitting devices each having a first electrode. A plurality of first electrodes in a same light-emitting unit is sequentially arranged along an arrangement direction of the plurality of thin-film transistors in a control unit corresponding to the same light-emitting unit.

Abstract: A light-emitting panel and a display device are provided. The light-emitting panel includes a base substrate, and a plurality of driving transistors and a plurality of light-emitting elements. One driving transistor is electrically connected to at least one light-emitting element. The plurality of light-emitting elements are arranged in an array to form one or more light-emitting element rows along a first direction and to form one or more light-emitting element columns along a second direction. In a direction parallel to a plane of the base substrate, the first direction intersects the second direction. In the direction parallel to the plane of the base substrate, a quantity of driving transistors adjacent to one light-emitting element is A, where A

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.
