Problems solved by technology

[0006] However, it is still relatively difficult to prepare high-quality organometal halide perovskite thin films with the current technology. Therefore, it is necessary to develop a new combination of organometal halide perovskite materials, which has a relatively simple manufacturing process, high stability, and high cost-effectiveness. OLED display device structure with good film quality and balanced carrier injection and transport

Abstract

The invention provides an OLED display device and a manufacturing method thereof. The OLED display device comprises: a substrate, an anode formed sequentially from bottom to top on the substrate, a hole injection layer, a hole transport layer, a light emitting layer, a hole A hole blocking layer, an electron transport layer, an electron injection layer, a cathode, a cover plate opposite to the substrate covering the substrate, and an encapsulant between the edge of the substrate and the cover plate; wherein, The material of the electron transport layer is a mixture of an organic electron transport material and an organic metal halide perovskite material, and the electronic transport layer can be enhanced by using a mixture of an organic electron transport material and an organic metal halide perovskite material to make the electron transport layer. The electron mobility of the transport layer balances the carrier injection and transmission of the OLED display device, improves the luminous efficiency of the OLED display device, reduces the difficulty of film formation, improves the film quality, and ensures the stability of the OLED display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display device and a manufacturing method thereof. Background technique [0002] Organic Light Emitting Display (OLED) display device has self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, nearly 180° viewing angle, wide operating temperature range, and can realize flexible display and With many advantages such as large-area full-color display, it is recognized by the industry as a display device with the most potential for development. [0003] OLED display devices belong to self-luminous display devices, and generally include pixel electrodes and common electrodes used as anodes and cathodes respectively, and an organic light-emitting layer arranged between the pixel electrodes and the common electrodes, so that when an appropriate voltage is applied to When the anode and cathode are connected, light is...
