Problems solved by technology

Since each sub-light-emitting unit includes a main light-emitting area and dark areas located on both sides of the main light-emitting area, the light at the junction of the dark areas between two adjacent sub-pixel units is relatively weak, which may form a screen division, so that the light-emitting area is not Cover the entire display panel
In addition, since each pixel unit includes three sub-pixel units of red, green, and blue, and the light emitted by the sub-light-emitting unit corresponding to each sub-pixel unit is emitted separately from the display panel, this will result in different sub-pixels. The colors are separated from each other

Abstract

The embodiment of the invention provides a light-emitting device, and relates to the technical field of display and illumination. The light-emitting device can increase the light-emitting area and achieve uniform and mixed light emergence. The light-emitting device comprises a back plate, a packaging structure, a light-emitting structure and a scattering layer, wherein the light-emitting structure and the scattering layer are arranged between the back plate and the packaging structure, the scattering layer is located at a light emergence side of the light-emitting structure, the light-emitting structure is separated into a plurality of light-emitting units, the scattering layer is separated into a plurality of scattering units, and the multiple light-emitting units correspond to the multiple scattering units one to one. Each light-emitting unit comprises a first light-emitting sub-unit, a second light-emitting sub-unit and a third light-emitting sub-unit and is applied to manufacturing of a display device and an illumination lamp.

Description

technical field [0001] The invention relates to the technical field of display and lighting, in particular to a light emitting device. Background technique [0002] In the existing technology, such as figure 1 As shown, an LED (Light Emitting Diode, light emitting diode) display panel or an OLED (Organic Light Emitting Diode, organic electroluminescent diode) display panel is mainly composed of a backplane 10, a packaging structure 40, and a light emitting structure 20 between them. Composition; wherein, each light-emitting unit of the light-emitting structure 20 adopts a tiled mode, that is, the first sub-light-emitting unit 201, the second sub-light-emitting unit 202, and the third sub-light-emitting unit 203 are alternately arranged on the backplane in the form of a plane 10 on. Since each sub-light-emitting unit includes a main light-emitting area and dark areas located on both sides of the main light-emitting area, the light at the junction of the dark areas between t...
