Embodiment

[0049] An embodiment of the present invention provides an organic electroluminescent device, such as figure 1 As shown, the first electrode 100 is a transparent anode, and the second electrode 300 is a metal cathode, that is, the organic electroluminescent device is a bottom-emitting device. The total microcavity length L of the organic light emitting diode in the bottom emitting organic electroluminescent device is the sum of the thickness L1 of the organic functional layer 200 and the thickness L2 of the first electrode 100 . In this embodiment, a white organic light emitting diode is used as an example for illustration. As an optional implementation manner, the organic light emitting diode can also be selected in other ways.

[0050] In the organic electroluminescence device of the embodiment of the present invention, the organic functional layer 200 includes three kinds of monochromatic light emitting layers, and the three kinds of monochromatic light are red light, green...

Embodiment approach

[0083] As another alternative embodiment of the present invention, when the organic electroluminescence device is a double-sided light-emitting device, during the manufacturing process, the thickness of the first electrode 100 and the second electrode 300 can be adjusted simultaneously to adjust the organic light emission. The purpose of diode microcavity length.

Abstract

The invention relates to the display technology field and provides an organic electroluminescence device manufacturing method, an organic electroluminescence device and a display device. The organic electroluminescence device manufacturing method contains a step of forming an organic light emitting diode and especially comprises the following steps of S1, forming a first electrode, an organic function layer and a second electrode which are stacked on a substrate, wherein the organic function layer includes at least one monochromatic light luminescent layer; and the first electrode and / or the second electrode are / is a light-emitting electrode; and S2, adjusting the thickness of the light-emitting electrode. By using the organic electroluminescence device manufactured by using the method ofthe invention, all monochromatic light generates uncorrelated optical resonance enhancement in the microcavity of the organic light emitting diode so that a purpose of enhancing the light extraction rate of all the monochromatic light is reached and then the luminous efficiency of the organic electroluminescence device is increased.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a method for preparing an organic electroluminescent device, an organic electroluminescent device and a display device. Background technique [0002] Organic Light Emitting Display (OLED) has self-luminescence, low driving voltage, high luminous efficiency, short response time, high definition and contrast, wide viewing angle, and can realize flexible display and large-area full-color display And many other advantages, it is recognized by the industry as the display technology with the most development potential. Among them, full-color display is one of its most important development goals. [0003] In the prior art, white light backlight combined with color filters is one of the main solutions for realizing full-color display. Since metal electrodes have certain light reflection properties, an optical microcavity is usually formed between two electrodes in an OLED device. In...
