Organic light emitting diode and electronic equipment

Abstract

The invention discloses an organic light emitting diode and a set of electronic equipment. The organic light emitting diode comprises a first carrier transport layer and a second carrier transport layer which are arranged opposite to each other and a light emitting layer. The light emitting layer comprises a first surface and a second surface which are opposite to each other, carriers transported by the first carrier transport layer enter the light emitting layer through the first surface, and carriers transported by the second carrier transport layer enter the light emitting layer through the second surface. The light emitting layer comprises a first light emitting sub-layer and a second light emitting sub-layer, wherein the first light emitting sub-layer is of a hollow structure, the second light emitting sub-layer comprises a body part and a protruding part, the protruding part protrudes out of the body part and is contained in the hollow structure, the surface of the first light emitting sub-layer and the surface of the protruding part form the first surface of the light emitting layer, and the surface of the body part forms the second surface of the light emitting layer. According to the organic light emitting diode and the electronic equipment, the working voltage is lowered, the power consumption is reduced, and the manufacturing technology is also simplified because the number of layers is reduced.

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 and green colors of 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-emit...

AI Technical Summary

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
