Abstract
The invention relates to the technical field of light-emitting diodes, in particular to a light-emitting diode, a light-emitting module and a display device. The light-emitting diode comprises an epitaxial layer, and the epitaxial layer comprises a first semiconductor layer, a second semiconductor layer and an active layer arranged between the first semiconductor layer and the second semiconductor layer; the first electrode is formed on the first semiconductor layer, the second electrode is formed on the second semiconductor layer, and the light-emitting diode is provided with a top edge, a bottom edge, a first side edge and a second side edge; the bottom edge is closer to the second electrode than the top edge; the second electrode at least comprises a starting part and two extending parts, the two extending parts are arc-shaped, and the two extending parts extend from the starting part, are gradually far away from the bottom edge and are gradually close to the first side edge and the second side edge respectively; and by taking a center line parallel to the side edge as a reference, an included angle which is not higher than 90 degrees is formed between a tangent line of each point of the extension part and the center line, and the included angle is gradually increased in the extension direction.
Description
technical field [0001] The invention relates to the technical field of light emitting diodes, in particular to a light emitting diode, a light emitting module and a display device. Background technique [0002] Light Emitting Diode, (Light Emitting Diode, referred to as LED), is a solid-state semiconductor device that can convert electrical energy into visible light. As a lighting device, compared with traditional lighting devices, light-emitting diodes have considerable advantages-long life, high luminous efficiency, no radiation, low power consumption, and green environmental protection. At present, LEDs are mainly used in fields such as display screens, indicator lights, and backlight sources. [0003] At present, LEDs have been widely used in the field of lighting. With the expansion of the application field, the requirements for the characteristics of LED products are also increasing; how to achieve the unity of long life, high reliability and high luminous efficiency ...
