A light emitting diode, display panel, display device and manufacturing method

Abstract

The disclosure 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 includes a light-emitting element, a planarization layer, an optical path adjustment layer, and a lens layer; the planarization layer is located between the light-emitting element and the lens layer; the optical path adjustment layer is arranged in the planarization layer; the optical path adjustment layer includes a first optical path adjustment layer and a second optical path adjustment layer. Two optical path adjustment layers, the first optical path adjustment layer and the second optical path adjustment layer form a V-shaped structure in the planarization layer; the plane where the first optical path adjustment layer is located and the plane where the second optical path adjustment layer is located have preset Included angle: the refractive index of the first optical path adjustment layer and the second optical path adjustment layer is greater than the refractive index of the planarization layer. In the present disclosure, by setting an optical path adjustment layer in the planarization layer, the optical path adjustment layer can adjust the outgoing direction of light to achieve the effect of light collimation.

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...
