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 invention provides an OLED display panel and a manufacture method thereof. The OLED display panel comprises a thin film transistor layer, an anode layer, an anode modification layer, a first public layer, a light emitting layer, a second public layer and a cathode layer. The anode modification layer is made of an azobenzene compound, wherein the azobenzene compound contains a functional groupused for transporting holes and a functional group used for enhancing the solubility in common organic solvents. In addition, the anode modification layer is in a three-dimensional relief grating structure. The OLED display panel has the advantages that by finely adjusting the three-dimensional grating structure of the anode modification layer, the micro-cavity effect of a top-emitting OLED devicecan be adjusted to improve the light color of an OLED device; and the light-out coupling efficiency of the device is enhanced.

Description

technical field [0001] The 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) display has many advantages such as thinness, active light emission, fast response speed, large viewing angle, wide color gamut, high brightness and low power consumption, etc., and has gradually become the successor. The third generation display technology after liquid crystal display. Compared with LCD (Liquid crystal displays, liquid crystal display), OLED has the advantages of saving power, being thinner, and having a wider viewing angle, which is incomparable to 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 comp...
