Description

technical field

[0001] The invention belongs to the technical field of organic luminescence, and in particular relates to a compound, a display panel and a display device. Background technique

[0002] An organic light emitting diode (OLED) is a self-luminous device that utilizes an organic thin film layer to generate electroluminescent light. Specifically, the OLED device is driven by an external electric field, and the anode and the cathode inject holes and electrons respectively; the holes and electrons migrate to the light-emitting layer and combine in the organic light-emitting material to generate excitons; the excitons in the excited state can be Release energy in the form of light to return to a stable ground state, producing visible light.

[0003] However, existing OLED devices still have the problem of low luminous efficiency. In addition to being related to the structure of OLED devices, the luminous efficiency of OLED devices is also greatly affected by the or...
