The embodiment of the invention provides an organic light-emitting display panel and an organic light-emitting display device. In the organic light-emitting display panel, structural layers of organic light-emitting components are doped with quantum dots, so that under the condition that the film thickness of each structural layer is not increased, light emitted by light-emitting layers can be converted into light with the colors corresponding to the organic light-emitting components, and thus the display panel can emit light with various colors through the organic light-emitting components; it should be noted that due to no increase in the film thickness of each structural layer, electron and / or hole transmission is not affected, and thus the light-emitting efficiency and the light-emitting brightness of the light-emitting layers are not affected; in addition, in the organic light-emitting display panel, the service life differences between light-emitting materials in any two organic light-emitting components are relatively small, and are not greater than a preset threshold, so that after the organic light-emitting display panel is used for a certain period of time, the attenuation degrees of the light-emitting brightness of the light-emitting materials have slight difference, the difference between the light-emitting brightness of the light-emitting materials is relatively small, and thus the problem of color deviation is alleviated to a certain extent.
Description
【Technical field】 [0001] The present invention relates to the field of organic light emitting display technology, in particular to an organic light emitting display panel and a device. 【Background technique】 [0002] Organic light-emitting display panels have self-luminous characteristics. Compared with liquid crystal displays, they have advantages such as fast response, thinner, wider viewing angle, and low power consumption, and have attracted more and more attention from the market. [0003] At present, a plurality of organic light emitting devices emitting red light, green light and blue light are generally arranged in an organic light emitting display panel, wherein, the light emitting layers of different organic light emitting devices are provided with light emitting devices for emitting colors corresponding to the organic light emitting device Light-emitting materials, by adjusting the brightness of organic light-emitting devices that emit red light, green light and b...
