Outdoor LED Display

An outdoor LED display assembly includes a receiving member and an LED display mounted on the receiving member. The LED display includes a heat sink and a plurality of LED modules mounted on the heat sink. The receiving member includes a bottom plate. A plurality of screw assemblies extends through the bottom plate to engage with the receiving member to mount the bottom plate on the receiving member. Each of the screw assemblies includes a screw and a circlip snapping with the screw.The bottom plate of the receiving member is sandwiched between the head and the circlip. Thus, when the screws are loosened from the receiving member, the screws are still remained on the bottom plate to prevent the screws from dropping from the outdoor LED display. A wire interconnects the bottom plate and the receiving member whereby the bottom plate is still attached to the receiving member even when the screws are all loosened from the receiving member.
