Problems solved by technology
[0005] It can be found that the OLED with the above-mentioned multi-layer light-emitting structure includes a large number of device layers. In order to drive holes / electrons to reach the light-emitting layer, a higher voltage is required, resulting in higher power consumption.
At the same time, more layers will increase the complexity of the process

[0073] The preparation of the above light-emitting layer is described below.
[0074] Such as figure 2 As shown, if the second luminescent sublayer is closer to the glass substrate, at this time, for the preparation of the luminescent layer, the following steps are included:
[0075] first forming a second luminescent material layer;
[0076] Then through a MASK process can be obtained as figure 2 the protrusion shown;
[0077] Finally, the first luminescent material layer is formed, and since part of the area is blocked by the protruding part, a hollow structure is naturally formed.
[0078] If the first luminescent sublayer is closer to the glass substrate, the preparation of the luminescent layer includes the following steps:
[0079] first forming a first luminescent material layer;
[0080] Then through a MASK process or printing process, you can get such figure 2 The first light-emitting layer with a hollow structure shown;
[0081] Finally, the second luminesc...

Abstract
The present invention discloses an organic light diode and electronic equipment, including organic light -emitting diode, including the first -load sub -transmission layer and the second load transmission layer of the relative settings, as well as the luminous layer.On the surface and the second surface, the carrier of the first carrier transmission layer transmission is entered into the luminous layer through the first surface,The second surface enters the luminous layer.In the hollow structure, the surface of the first optical layer and the surface of the protruding part of the first optical layer form the first surface of the light layer, and the surface of the body forms the second surface of the light layer.The present invention reduces the working voltage and reduces power consumption. At the same time, due to the reduction of the number of layers, the production process is also simplified.
Description
technical field [0001] The invention relates to an organic light-emitting diode, in particular to an organic light-emitting diode and electronic equipment with low power consumption and simple manufacture. Background technique [0002] At present, full-color display is one of the goals of the development of Organic Light Emitting Diode (OLED). Full-color images need to obtain continuously adjustable colors in the visible light wavelength range, and white light just covers the red, green and blue in the entire visible light region. If the white light OLED is combined with the relatively mature microelectronic etching color filter film technology, a full-color OLED with simple preparation process, good repeatability and low cost can be obtained. [0003] At present, there are many kinds of structures for realizing white light OLEDs, including multiple device stack structures, color conversion structures, single-layer light-emitting layer structures, and multi-layer light-emitt...
