Embodiments of the present invention provide an organic light-emitting display panel and device. In the embodiments of the present invention, quantum dots are doped in the structural layers of organic light-emitting devices, so that light can be emitted without increasing the film thickness of each structural layer. The light emitted by the layer is converted into the light of the corresponding color of the organic light-emitting device, so that the display panel can emit light of various colors through each organic light-emitting device. It should be noted that without increasing the film thickness of each structural layer, it will not affect The transport of electrons and / or holes will not affect the luminous efficiency and luminous brightness of the light-emitting layer; in addition, in the above-mentioned organic light-emitting display panel, the difference in the lifetime of the light-emitting materials in any two organic light-emitting devices is small, both If the above-mentioned organic light emitting display panel is used for a period of time, the attenuation degree of the luminous brightness of each luminescent material is not much different, and the difference of luminous luminance of each luminescent material is small, which alleviates the color cast to a certain extent. The problem.
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...
