摘要： An organic electroluminescent device adopts a TADF material as a first host material (6) of a green light unit (302) to sensitize a green phosphorescent material serving as a first guest material (7). A portion of triplet excitons are converted into singlet excitons through inverse gap crossing, and thus decrease of the triplet exciton concentration results in narrowing of the recombination region, thereby preventing the triplet excitons from diffusing into a blue light layer (4) to emit light, so as to realize a green light spectrum containing no blue light component. And because an energy level difference between red light and blue light is relatively large, carriers in a red light unit cannot be easily transferred to the blue light layer, and therefore it is not easy for a blue light component to appear in a red light spectrum. Accordingly, the light-emitting spectrums of red/green subpixels in the organic electroluminescent device with a shared blue light layer do not contain blue light, thereby effectively broaden the range of applicable combinations of luminescent materials and improving the display performance of the device. Moreover, a hole-blocking layer is not required, and thus the structure of the device is effectively simplified, and the operation voltage is lowered; in the meantime, the process difficulty is reduced, and the product yield is increased, thereby reducing the production cost.
