Title:
DISPLAY PANEL, PREPARATION METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/000995
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of display, and provides a display panel, a preparation method therefor, and a display device. The display panel comprises a drive backplane, a light-emitting functional layer and a light extraction layer. The light-emitting functional layer and the light extraction layer are sequentially located on a bearing surface of the drive backplane. The light-emitting functional layer comprises a plurality of light-emitting units arranged in an array. The light extraction layer comprises a first sub-layer and a second sub-layer. The first sub-layer and the second sub-layer are sequentially stacked on the light-emitting functional layer. The refractive index of the first sub-layer is lower than the refractive index of the second sub-layer. The first sub-layer has a plurality of grooves. Each of the plurality of grooves is opposite to one of the light-emitting units. A portion of the second sub-layer is located in the plurality of grooves. The boundary length of a groove is greater than the boundary length of a light-emitting region of a corresponding light-emitting unit. According to the present disclosure, more light can be emitted from the display panel, and the light-emitting effect of the display panel is enhanced.
