Abstract: Provided is a Light Emitting Diode (LED) display device.

Abstract: A connecting device and a display screen with the same. Wherein, the connecting device includes: a first connecting member, including a first fixed part, a first movable part and a first elastic part positioned between the first fixed part and the first movable part, the first fixed part being provided with a first component connecting part and the first movable part being provided with a mounting through hole; and a second connecting member matched with the first connecting member, the first movable part having a connection state of causing the hole wall of the mounting through hole to extend into the accommodation groove and a separation state of causing the hole wall of the mounting through hole to extend out of the accommodation groove and the first movable part being in the connection state only under the action of the first elastic part.

Abstract: The invention provides a connecting structure and a Light-Emitting Diode (LED) display device having the same. The connecting structure comprises: a first pressing plate, which including a plate body and a lock sheet provided on the plate body slidably, a first mounting hole is provided on the plate body; a second mounting hole is provided on a second pressing plate; a connecting column, penetrating through the first mounting hole and the second mounting hole respectively, a lock groove matched with the lock sheet is provided on a first end of the connecting column, a force application part located below the second pressing plate is provided on a second end of the connecting column; a lifting mechanism, connected to the second pressing plate, the second pressing plate may move towards or away from the first pressing plate under an action of the lifting mechanism by operating the force application part.
