Abstract

The invention discloses a display panel and a display device. The display panel includes an organic electroluminescent device; and a color conversion layer which is arranged on the organic light-emitting device, wherein the color conversion layer comprises a quantum dot material and an organic light-emitting material. The invention provides a display panel and a display device. The organic electroluminescent material is added in the color conversion layer, the organic electroluminescent material forms excitons under the excitation of blue light through the mixing of the organic electroluminescent material and the quantum dot material, and then the singlet excitons are transferred to the quantum dots through fluorescence resonance energy transfer, so the efficiency of the color conversion layer is improved.

Description

technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel and a display device. Background technique [0002] Large-size organic light-emitting diode (Organic Light-Emitting Diode, OLED) display device, in order to achieve 8K resolution, the aperture ratio of the bottom gate device decreases due to the increase in the number of TFTs, and the device life of OLED is reduced to one-third of that of 4K OLED TV one. Top-gate devices mainly include two technical solutions: top-emitting white light plus color filter and top-emitting blue light plus quantum dot color filter (or quantum dot film). [0003] Large-size OLED display devices, especially quantum dot organic electroluminescent devices with blue light plus quantum dot color filters, due to the low conversion efficiency of quantum dots, it is urgent to improve the efficiency of the light conversion layer. [0004] Therefore, it is really necessary to d...
