A display panel includes: a first base substrate including sub-pixel areas; first light-emitting devices corresponding to the sub-pixel areas one by one; a first dam layer including first opening areas; first photoluminescent layers on a side of the first light-emitting devices away from the first base substrate and in at least part of the first opening areas; second light-emitting devices on a side of the first dam layer away from the first light-emitting devices; a second dam layer on a side of the second light-emitting devices away from the first base substrate and including second opening areas corresponding to the sub-pixel areas one by one; and second photoluminescent layers on a side of the second light-emitting devices away from the first base substrate and in at least part of the second opening areas. Orthographic projections of the second light-emitting devices do not overlap with the sub-pixel areas.

Display panel and manufacturing method therefor, and display device and driving method therefor

The embodiment of the present disclosure provides a display panel and a display device. The display panel includes: a first sub-pixel configured to display a first color, a second sub-pixel configured to display a second color, and a third sub-pixel configured to display a third color; when a picture displayed by the display panel is switched from a black picture to a picture having a maximum gray scale of the first color, the second color and the third color, respectively, a ratio of a brightness of a first frame of picture to a maximum value among brightness of stabilized several frames of pictures is a first initial frame brightness proportion, a second initial frame brightness proportion and a third initial frame brightness proportion, respectively; the first, second and third initial frame brightness proportions have a Max-Min less than or equal to a threshold.
