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 invention discloses a micro light emitting diode display panel, a manufacturing method thereof and a display device, and relates to the technical field of display. The display panel comprises a receiving substrate and a plurality of micro light emitting diodes, wherein the receiving substrate comprises a substrate and a pixel limiting layer, the pixel limiting layer is provided with a plurality of grooves, and the micro light emitting diodes are located in the grooves; at least part of the side wall of the groove is covered with conductive metal, and the conductive metal comprises a firstbinding electrode; the micro light-emitting diode comprises a light-emitting body, a first electrode and a second electrode, and the first electrode is in contact with the first binding electrode; theincluded angle between the surface, making contact with the first binding electrode, of the first electrode and the bottom face of the groove is an obtuse angle. The included angle between the contact surface of the first electrode and the first binding electrode and the bottom surface of the groove is set to be the obtuse angle, and the first electrode and the first binding electrode are in inclined surface contact, so when the micro light emitting diode is impacted in use, the micro light emitting diode has stronger stripping resistance and is not easy to fall off, and the reliability of aproduct is improved.

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...
