Abstract

This application relates to the field of display technology, and discloses a light-emitting unit, including: a light-emitting semiconductor, including a first semiconductor layer, an active layer, and a second semiconductor layer stacked in sequence, and a recessed structure, wherein the recessed structure includes a recessed The top and the bottom of the depression, the bottom of the depression or the top of the depression is located in the first semiconductor layer; the first electrode includes a first part and a second part; wherein the first part is arranged on the first semiconductor layer; The second part is arranged on the side of the light-emitting unit, and the second part includes a light-isolating material. The display device provided by the present application avoids the transmission of the light emitted by the light-emitting units to each other as much as possible, and prevents the light crosstalk between the light-emitting units as much as possible, which is beneficial to improve the display effect, and also simplifies the structure of the display device. The application also discloses a light emitting device and a display device.

Description

technical field [0001] The present application relates to the field of display technology, for example, to a light emitting unit, a light emitting device and a display device. Background technique [0002] At present, light-emitting units are usually used in the display field, for example, in Micro LED products, light-emitting units are used for display. [0003] In the process of implementing the embodiments of the present disclosure, it is found that at least the following problems exist in related technologies: [0004] Part of the light emitted by the light-emitting unit will be transmitted to other light-emitting units, resulting in optical crosstalk between the light-emitting units and affecting the display effect. Contents of the invention [0005] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is presented below. This summary is not intended to be an extensive overview or to identify key / critical elements o...
