The control unit 94 executes the first and second controls in a specific order as the brightness of the image based on the pixel signals becomes brighter.

The application provides a display panel and a preparation method of the display panel. The display panel comprises a substrate, a light-emitting device layer and a chromaticity adjustment layer. The light-emitting device layer is located on one side of the substrate, and comprises a plurality of light-emitting pixel units. The chromaticity adjustment layer is located on the side of the light-emitting device layer away from the substrate, and comprises a plurality of chromaticity adjustment units.

The invention belongs to the technical field of display, and relates to a photoelectric device, a preparation method thereof and a display device. The photoelectric device comprises a first electrode, a first quantum dot layer, a second quantum dot layer and a second electrode which are sequentially stacked. The first quantum dot layer is made of a first quantum dot material, the second quantum dot layer is made of a second quantum dot material, and the band gap of the first quantum dot material is larger than that of the second quantum dot material. The band gap of the first quantum dot layer is larger than that of the second quantum dot layer, so that when the photoelectric device works, the first quantum dot layer serves as a light harvesting antenna, an internal material of the first quantum dot layer transitions to an excited state after absorbing exciting light energy, and excitons are all converged into the second quantum dot layer with a relatively narrow band gap through energy transfer; therefore, the second quantum dot layer plays a main light-emitting role, and the light-emitting brightness and external quantum of the light-emitting device are further improved.
