Background technology
Organic electroluminescence device (OLED) obtains extensive investigation and application with the photoelectric properties of its uniqueness in display and lighting field.For realizing high-resolution display further and improving its luminescent properties and application, OLED starts to change from traditional bottom-emission to top emitting and double-side.
As everyone knows, OLED is primarily of two electrodes and organic function layer composition, and the first electrode is prepared on substrate, and organic function layer is prepared on the first electrode, and the second electrode is prepared on organic function layer.Under normal circumstances, adopt metal conductive oxide material, such as tin indium oxide (ITO) and indium zinc oxide (IZO), on substrate, prepare the first electrode by the method for magnetron sputtering, this electrode generally all has higher transparency.In order to realize double-side, just need the transparency simultaneously improving the second electrode; And in order to realize top emitting, the transparency of raising second electrode while, the transparency of the first electrode also should be reduced.
