Display panel, preparation method and display device

Abstract

The embodiment of the invention discloses a display panel, a preparation method and a display device. The preparation method comprises following steps: providing a plurality of micro light-emitting diodes, a plurality of reflection retaining wall structures, a packaging cover plate and an array substrate, wherein the packaging cover plate comprises a cover plate and a transparent fixing layer located on one side of the cover plate; the array substrate comprises a substrate body and a conductive layer located on one side of the substrate body; and the conductive layer comprises a plurality of conductive electrodes; respectively transferring the plurality of micro light-emitting diodes and the plurality of reflection retaining wall structures to the packaging cover plate, and fixing the micro light-emitting diodes and the reflection retaining wall structures on the packaging cover plate through a transparent fixing layer, wherein at least one micro light emitting diode forms a pixel unit and the reflection retaining wall structures are located between the adjacent pixel units; attaching the packaging cover plate and the array substrate in an aligned mode, wherein the attaching mode is that the side, provided with the micro light-emitting diodes, of the packaging cover plate is attached to the conductive layer of the array substrate in an aligned mode, the conductive electrodes are electrically connected with the micro light-emitting diodes in a one-to-one correspondence mode, and the cover plate is reused as a packaging layer of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular, to a display panel, a manufacturing method, and a display device. Background technique [0002] At present, Micro Light Emitting Diode (Micro LED) display panels are increasingly attracting attention from the display market due to their advantages such as high brightness, low operating voltage, low power consumption, long life, impact resistance and stable performance. [0003] In the prior art, when preparing a Micro LED display panel, a barrier structure is provided between adjacent Micro LEDs to prevent crosstalk between light rays emitted by adjacent Micro LEDs. However, when the retaining wall structure is prepared, the preparation process and / or height setting of the retaining wall structure will have a new impact on the Micro LED, thereby affecting the normal light emission of the Micro LED. Contents of the invention [0004] In view of this, an...
