Abstract
An organic light emitting diode (OLED) display panel and preparation method thereof, which includes an array substrate, an organic light emitting layer, and an encapsulation layer. The encapsulation layer includes organic-inorganic functional layer. Through disposing the organic-inorganic functional layer, the overall thickness of the encapsulation thin film can be reduced while ensuring the encapsulation effect, and the bending performance of the OLED device can be improved. Further, a mask plate is not required in the encapsulation process, thereby can effectively save production cost.
