Problems solved by technology

Achieving large-scale display requires the use of TFT drive technology, while traditional bottom-emitting OLEDs (BOLEDs) use indium tin oxide (ITO) anodes on transparent substrates as the light-emitting surface. When using non-transparent silicon substrates When the bottom or amorphous silicon with low mobility or organic TFT is used as the substrate, it is easy to cause the problem of low aperture ratio

Abstract

The present invention proposes an OLED display panel and a manufacturing method thereof. The OLED display panel includes a thin film transistor layer, an anode layer, an anode modification layer, a first common layer, a light-emitting layer, a second common layer, and a cathode layer; wherein, the The material of the anode modification layer is an azobenzene compound, and the azobenzene compound contains a functional group for transporting holes and a functional group for enhancing its solubility in common organic solvents; in addition, the The anode modification layer is a three-dimensional relief grating structure. Beneficial effects: through the fine adjustment of the three-dimensional grating structure of the anode modification layer, the adjustment of the microcavity effect of the top-emitting OLED device can be realized, and the light color of the OLED device can be improved, and at the same time, the light coupling efficiency of the device can also be enhanced. Effect.

Description

Technical field [0001] The present invention relates to the technical field of flat panel display manufacturing, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] In flat panel display technology, Organic Light-Emitting Diode (OLED) displays have many advantages, such as light and thin, active light emission, fast response speed, large viewing angle, wide color gamut, high brightness and low power consumption. The third-generation display technology after the liquid crystal display. Compared with LCD (Liquid crystal displays), OLED has the advantages of more power saving, thinner, and wide viewing angle, which is unmatched by LCD. At present, people have higher and higher requirements for the fineness of the display, that is, the resolution, but the production of high-quality, high-resolution OLED displays still faces many challenges. [0003] The core component of an OLED display device is an OLED display panel. The traditio...
