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

A display panel includes a first base substrate, a light-emitting device layer located on a side of the first base substrate, a color filter layer located on a side of the light-emitting device layer away from the first base substrate, a color conversion layer located between the light-emitting device layer and the color filler layer, a touch function layer located on a side of the color conversion layer away from the first base substrate and a light adjustment layer located on a side of the touch function layer away from the first base substrate. The light adjustment layer includes first particles and second particles. The first particles each include dye molecules. The second particles each have a hollow structure.

Display panel and color filter substrate

Provided are a display substrate, a manufacturing method thereof, a display device. The display substrate includes sub-pixel units on a base layer, each sub-pixel unit includes a light propagation unit including a first medium structure and a second medium structure, orthographic projections of the first medium structure and the light emitting unit on the base layer are at least partially overlapped, the second medium structure contacts at least one side of the first medium structure. The first medium structure has a refractive index larger than that of the second medium structure. A first included angle between a diagonal line and a bottom side of a first cross section of the first medium structure is equal to a total reflection angle at a contact surface between the first medium structure and the second medium structure. The first included angle is smaller than or equal to a preset angle.
