Abstract

The invention relates to the technical field of display, in particular to an organic electroluminescence device and a preparation method thereof. The organic electroluminescence device comprises a transparent substrate, a first electrode mechanism, an organic light-emitting layer and a second electrode mechanism, wherein the first electrode mechanism comprises a plurality of first electrodes and a plurality of second electrodes; each first electrode corresponds to one sub-pixel unit; each second electrode corresponds to one sub-pixel unit; the first electrodes and the second electrodes are alternately distributed along the row directions and / or column directions of pixel units; the second electrode mechanism is a transparent electrode layer with a plate-type structure; the light transmittance of the first electrodes is greater than that of the second electrode mechanism; the reflectivity of the first electrodes is smaller than that of the second electrode mechanism; the light transmittance of the second electrodes is smaller than that of the second electrode mechanism; and the reflectivity of the second electrodes is greater than that of the second electrode mechanism. The organic electroluminescence device can achieve dual-side independent display when achieving transparent display.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic electroluminescence device and a preparation method thereof. Background technique [0002] At present, the application of organic electroluminescent devices (Organic Light-Emitting Diode, OLED) in the display field has been relatively mature. Organic electroluminescent devices are thin-film devices similar to a sandwich structure. The layer can be a hole injection layer, a hole transport layer, a light emitting layer, an electron transport layer, an electron injection layer, and the like. Organic electroluminescent devices are electro-injection light-emitting components. After the anode and cathode are applied with operating voltage, holes are injected from the anode and electrons are respectively injected into the organic material layer from the cathode, and the two types of carriers form holes in the organic light-emitting material. Hole-electron pairs emit light. ...
