Abstract: A display device includes first and second display modules and first and second turning pieces that include a first coupling piece, a first turning piece, a second turning piece, and a third turning piece, a second coupling piece and a guiding device. When the first and second display modules are switched between folding and unfolding, the first turning piece pivots relative to the first coupling piece and the second turning piece, and the third turning piece pivots relative to the second coupling piece and the second turning piece. When the display module is switched from folded to unfolded, the other side of the first display module relative to the side is pulled, the side of the first display module is guided by one end of the guiding device and slides to the other end, the first and second display modules are symmetrically unfolded with the side edge as the center.

Abstract: The present invention provides a multi-directional multi-joint turning piece and a display device including the multi-directional multi-joint turning piece. The multi-directional multi-joint turning piece is configured to connect a first display module and a second display module to provide a first display module unfolded or folded with the second display module. The multi-directional multi-joint turning piece includes a first coupling piece, a first turning piece, a second turning piece, a third turning piece, and a second coupling piece, wherein the first coupling piece is connected to the first display module, the second coupling piece is connected to the second display module, the first coupling piece is pivoted to the first turning piece, the first turning piece is pivoted to the second turning piece, the second turning piece is pivoted to the third turning piece, and the third turning piece is pivoted to the second coupling piece.

Abstract: A structure for a high diffuse efficiency and water-proof lighting device is provided, including a light tube and a base holder. The light tube and the base holder are each an enclosed structure. The light tube includes a circuit substrate inside the enclosed structure. The circuit substrate includes a plurality of LEDs. The light tube and the base holder each include two holes close to both ends. When the light tube and the base holder are assembled, the holes match so that the wire connecting the circuit substrate can go through the holes to enter the base holder. A water-proof and highly pull-resistant glue is used to fill the overlapping of the holes. A resilient element is used to connect the neighboring circuit substrates, the resilient element can absorb the deformation caused by the temperature changes so that the light diffusion remains uniform. Therefore, the lighting device can perform well even when operating in an environment with drastic temperature changes.
