Abstract: A display panel includes a driving backplane, a light emitting component, a reflective structure and a bridging component. The driving backplane has a first pad and a second pad separated from each other. The light emitting component has a first electrode and a second electrode. The first electrode is electrically connected to the first pad of the driving backplane, and the first electrode is located between the second electrode and the first pad of the driving backplane. The reflective structure is disposed on the driving backplane and located at a periphery of the light emitting component. The bridging component is disposed on the light emitting component. One end of the bridging component is electrically connected to the second electrode. The bridging component passes across at least one portion of the reflective structure. The other end of the bridging component is electrically connected to the second pad of the driving backplane.

Abstract: A high speed assembly connection structure that consists of a direction screw of a connector head that fits in a direction slot of a tool element which causes the tool element to be limited to a specified direction. A set screw of the connector head protrudes into a cambered groove of the handle, which limits the rotation of the handle within a specified range. An entry position notch of the handle holds the tool element in a specified direction during assembly and a mounting slot of the tool element enables the tight engagement of the handle after the handle is rotated. Furthermore, in the operation of this structure, no additional tools are required to accomplish the rapid installation of the tool element.
