Disclosed is an arc-shaped adjustment lock, including: a base, an adjustment component, and a pressing lock assembly. The base is connected to a first LED cabinet. The base has a first arc-shaped portion. The adjustment component is connected to a second LED cabinet. The adjustment component has a second arc-shaped portion fitted with the first arc-shaped portion. The first arc-shaped portion and the second arc-shaped portion are slidingly matching with two elastic beads along an arc through a staggered double V-shaped groove group. The first arc-shaped portion and the second arc-shaped portion are locked through the pressing lock assembly after sliding along the arc.

A display device includes a display panel, a frame disposed on a rear surface of the display panel, a plurality of panel magnets disposed in the frame, a plurality of panel ferromagnetic substances disposed on both side surfaces of each of the plurality of magnets, and a connecting module disposed on the rear surface of the display panel and having a connecting plate for supplying power to the display panel, in which the connecting plate is configured to protrude outside the frame or be positioned more inward than the rear surface of the frame depending on the detachment from the panel ferromagnetic substances of the connecting module.

Disclosed is a high quality display device which avoids complicated element structure, and does not unnecessarily reduce portability. The display device comprises: a pair of substrates which are disposed facing each other, and on each of which electrodes are formed; and a material layer which is sandwiched between the pair of substrates. The material layer contains: a coloring material which changes color upon the application of a voltage; and a light-emitting material which emits light upon photoexcitation.

The present disclosure provides a display device, including first to fourth LEDs, a line structure, and first to fourth lines. The second LED is arranged in a first direction corresponding to the first LED. The fourth LED is arranged in a second direction corresponding to the third LED. The line structure includes first to third line segments. The first line is coupled to the first LED. The second line is coupled to the second LED. The third line is coupled to the third LED. The fourth line is coupled to the fourth LED. A portion of the first line and a portion of the second line are in parallel with the first line segment, a portion of the third line is in parallel with the second line segment, and a portion of the fourth line is in parallel with the third line segment.

A multi-angle attachable display device includes a polygonal light emitting module and a control module. The light emitting module has a light emitting layer with at least one light emitting unit, a module driver, and multiple connection ports. The at least one light emitting unit includes a unit driver that electrically connects the module driver. Each of the connection ports is mounted on a side surface of the light emitting layer and electrically connected to the module driver. The control module includes a controller connection port, a wireless communication unit, and a processing unit. When the controller connection port is connected to one of the connection ports of the light emitting layer, the processing unit detects a connection pathway of the light emitting module, and the processing unit generates and sends a light pattern signal to control the unit driver through the controller connection port and the module driver.

A modular distributed control LED display system, comprising several LED display module units (100) which are spliced together to form an integrated LED display screen, each of the LED display module units (100) comprises a lamp board (110) and an independent controller (120), wherein the lamp board (110) is provided with a number of LED light sources, and the independent controller (120) is provided on the back of the lamp board (110), the independent controller (120) is used to control the working state and display mode of the LED light sources.
