Problems solved by technology

[0003] Since the light emitted by conventional light-emitting diodes is composite light, the light will be emitted in all directions, and will produce outgoing light at various angles after reflection, which will eventually cause unnecessary stray light interference and affect the overall light emission, resulting in energy loss and reduced luminescence. The light extraction efficiency of the diode

Embodiment Construction

[0038] In order to more clearly understand the above objects, features and advantages of the present disclosure, the present disclosure will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are some of the embodiments of the present disclosure, but not all of the embodiments. The specific embodiments described here are only used to explain the present disclosure, but not to limit the present disclosure. All other embodiments obtained by persons of ordinary skill in the art based on the described embodiments of the present disclosure belong to the protection scope of the present disclosure.

[0039] The angles of the light emitted by the light-emitting diodes are different, and the light will be emitted at various angles, causing unnecessary stray light interference and reducing the light extraction efficiency. In the prior art, a collimator lens is usually connected to th...

Abstract

The invention relates to a light-emitting diode, a display panel, a display device and a preparation method, and relates to the technical field of light-emitting diodes. The light-emitting diode comprises a light-emitting element, a planarization layer, a light path adjusting layer and a lens layer. The planarization layer is located between the light-emitting element and the lens layer; the light path adjusting layer is arranged in the planarization layer; the light path adjusting layer comprises a first light path adjusting layer and a second light path adjusting layer, and the first light path adjusting layer and the second light path adjusting layer form a V-shaped structure in the planarization layer; the plane of the first light path adjusting layer and the plane of the second light path adjusting layer respectively have a preset included angle with the plane of the light-emitting element; and the refractive index of the first light path adjusting layer and the refractive index of the second light path adjusting layer are larger than the refractive index of the planarization layer. According to the invention, the light path adjusting layer is arranged in the planarization layer, and the light path adjusting layer can adjust the light emitting direction, so that the light collimation effect is realized.

Description

technical field [0001] The present disclosure relates to the technical field of light emitting diodes, in particular to a light emitting diode, a display panel, a display device and a preparation method. Background technique [0002] With the development of light-emitting diode technology, light-emitting diodes are widely used in various fields, including various display systems, lighting systems, electronic products and so on. The light-emitting diode itself has the characteristics of small size, simple structure and long service life, so it has received more attention. [0003] Since the light emitted by conventional light-emitting diodes is composite light, the light will be emitted in all directions, and will produce outgoing light at various angles after reflection, which will eventually cause unnecessary stray light interference and affect the overall light emission, resulting in energy loss and reduced luminescence. The light extraction efficiency of the diode. Con...
