Problems solved by technology

[0006] In order to solve the problem that the internal current of the light-emitting diode will be abnormal after the structure shape or position of the contact electrode mentioned in the above-mentioned background technology is changed, and the resulting current change will cause the light-emitting diode to emit relatively unevenly. The present invention provides a light-emitting diode Diodes, including:

Abstract

The invention relates to the technical field of light-emitting diode manufacturing, in particular to a light-emitting diode, a photoelectric module and a display device. By controlling the minimum distance between the strip-shaped part of the second contact electrode of the light-emitting diode and the geometric center of the surface of the light-emitting diode, an ejector pin operation window is expanded, the problem that a chip is abnormal due to the fact that an ejector pin is prone to bursting a protruding area of the contact electrode is solved, and by arranging the passing position on the second bonding pad electrode, the problem of non-uniform light emitting of the light-emitting diode caused by current change due to the change of the contact electrode is avoided.

Description

technical field [0001] The invention relates to the technical field of light-emitting diode manufacturing, in particular to a light-emitting diode, a photoelectric module and a display device. Background technique [0002] Light Emitting Diode (English: Light Emitting Diode, referred to as: LED) has the advantages of low cost, high luminous efficiency, energy saving and environmental protection, and is widely used in lighting, visible light communication, and light-emitting display and other scenarios. LED chips are divided into three types: positive structure, flip structure and vertical structure. Compared with traditional front-mounted chips, flip-chips have the advantages of high current, reliability, and ease of use, and have been used on a large scale. [0003] At present, some flip-chip LEDs include a substrate and an epitaxial structure, and the epitaxial structure includes a first semiconductor layer, a light-emitting layer, and a second semiconductor layer stacked...
