FUNCTIONAL MATERIAL, PREPARATION METHOD THEREFOR, ORGANIC LIGHT-EMITTING DIODE DISPLAY PANEL

摘要

The present invention relates to the technical field of displays and is capable of solving the problem of pollution found in existing organic light-emitting diode display panels. Provided are a functional material, a preparation method therefor, and an organic light-emitting diode display panel. The functional material of the present invention comprises an inorganic mixed powder having a modified layer produced from a dianhydride and a diamine. The inorganic mixed powder is selected from boron oxide, sodium oxide, lithium oxide, zirconium oxide, aluminum oxide, zinc oxide, titanium dioxide, silicon dioxide, calcium oxide, a silver complex, silver phosphate, silver nitrate, tourmaline, silver thiosulfate, carbon nanotubes, aluminum sulfate, manganese, oxides of manganese, iron, oxides of iron, cobalt, oxides of cobalt, nickel, oxides of nickel, chromium, oxides of chromium, copper, oxides of copper, magnesium oxide, boron carbide, silicon carbide, titanium carbide, zirconium carbide, tantalum carbide, molybdenum carbide, boron nitride, chromium nitride, titanium nitride, zirconium nitride, aluminum nitride, chromium boride, chromium(III) tetraboride, titanium diboride, zirconium boride, tungsten disilicide, and titanium disilicide.
