Abstract

The invention provides a micro LED chip structure, a manufacturing method thereof and a display panel. The manufacturing method comprises the following steps: providing a driving backboard, wherein the driving backboard comprises a first region and a second region which are adjacent, the first region surrounds the second region, and the first region is provided with a driving electrode; transferring a micro LED chip to the second region, wherein the micro LED chip comprises a device electrode, and the device electrode protrudes in the direction away from the driving backboard; and forming a bridging electrode, wherein the bridging electrode is connected with the device electrode and the driving electrode.

Description

technical field [0001] The invention belongs to the technical field of manufacturing semiconductor devices, and in particular relates to a micro LED chip, a manufacturing method and a display panel. Background technique [0002] In recent years, semiconductor micro-LED chips have developed rapidly as an active light-emitting micro-display technology. The application scenarios of micro-LED chip display technology cover all display ranges, such as large commercial display screens, TVs, mobile phones, vehicle displays, AR and VR, etc. In particular, the micro-LED chip display technology used in micro-displays such as AR and VR has incomparable advantages over other display technologies, such as high brightness and high pixel density. [0003] At present, the relevant technologies for the application of micro-LED chips in the production of display panels are still immature, and the production schemes are based on different mass transfer methods and repair methods. The micro LED...
