ORGANIC LIGHT-EMITTING DIODE AND PREPARATION METHOD THEREFOR, AND ORGANIC LIGHT-EMITTING DIODE DISPLAY APPARATUS

摘要

An organic light-emitting diode (100) and a preparation method therefor, and an organic light-emitting diode display apparatus. The organic light-emitting diode (100) comprises: an anode (10), a hole injection layer (11), a hole transport layer (12), an electron blocking layer (13), an organic light-emitting layer (14), a hole blocking layer (15), an electron transport layer (16), and a cathode (18), wherein a first composite layer (110) is provided between the electron blocking layer (13) and the organic light-emitting layer (14), and the first composite layer (110) comprises a material of the electron blocking layer (13) and a host material of the organic light-emitting layer (14).
