Abstract
An organic light-emitting diode (OLED) display panel and a manufacturing method thereof are provided. An organic material and an inorganic nano-particle material are placed in a crucible under a high-pressure gas after vacuuming, the inorganic nanoparticles and the organic material are highly uniformly mixed during an evaporation process, and an encapsulation layer is formed integrally into one piece by adjusting an evaporation rate ratio of the organic material to the inorganic nano-particle material. The film layer stability and transmittance are optimized, and the inorganic nanoparticles are uniformly distributed, thereby improving the light transmittance of the OLED display panel.
