Embodiment Construction

[0032] Certain terms are used, for example, in the description and claims to refer to particular components. Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. The specification and claims do not use the difference in name as a way to distinguish components, but use the difference in function of components as a criterion for distinguishing. As mentioned throughout the specification and claims, "comprising" is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problem within a certain error range and basically achieve the technical effect. In addition, the term "coupled" herein includes any direct and indirect electrical coupling means. Therefore, if it is described that a first device is coupled to a second device, it means that the first device may be directly elect...

Abstract

The application discloses a micro-light-emitting diode display panel, its manufacturing method and display device, which relate to the field of display technology and include: a receiving substrate and a plurality of micro-light-emitting diodes; the receiving substrate includes a substrate and a pixel defining layer, and the pixel defining layer is provided with a plurality of The groove, the micro light emitting diode is located in the groove; at least part of the side wall of the groove is covered with conductive metal, the conductive metal includes the first binding electrode; the micro light emitting diode includes a light emitting body, a first electrode and a second electrode, the first The electrode is in contact with the first binding electrode; wherein, the angle between the surface of the first electrode in contact with the first binding electrode and the bottom surface of the groove is an obtuse angle. In this application, by setting the angle between the surface of the first electrode in contact with the first binding electrode and the bottom surface of the groove as an obtuse angle, the contact between the first electrode and the first binding electrode is an inclined plane, and when it is impacted during use , the micro-light-emitting diode has a stronger ability to resist peeling, and is not easy to fall off, which is beneficial to improving the reliability of the product.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a micro light emitting diode display panel, a manufacturing method thereof and a display device. Background technique [0002] Micro light-emitting diode (Micro light-emitting diode, Micro LED) is a light-emitting diode with a size of micron. Due to the small size of Micro LED, it can be used as a pixel on a display panel. The display panel prepared by using Micro LED can be It is called Micro LED display panel. Compared with Organic Light-Emitting Diode (OLED) display panels, the service life and viewing angle of Micro LED display panels are superior to OLED display panels, so Micro LED display technology has become the focus of research in the field of display technology. [0003] In the manufacturing process of the micro-LED display panel, it is necessary to first form the micro-light-emitting diode on the original substrate, and then use the transfer head to absor...
