The image processing device displays, on a display, a virtual screen obtained by viewing, from above, an aggregate board in which multiple unit boards having a common component configuration are arranged. A control section of the image processing device uses one unit board at a predetermined position among the multiple unit boards as a reference unit board, generates a detailed image in which respective components are arranged on the unit board based on positional information of all components to be mounted on the unit boards, for the reference unit board, generates a simplified image obtained by simplifying the unit board, for a non-reference unit board other than the reference unit board among the multiple unit boards, and displays a simple virtual screen displaying the detailed image at a position of the reference unit board and the simplified image at a position of the non-reference unit board as the virtual screen.

A display unit has a base with a base plate, a set of reflectors and a transparent or translucent cover. The base plate has an array of openings. Each opening is sized to receive a light socket from a string of lights and hold the light socket. There is one reflector for each opening in the base plate positioned adjacent a respective opening in the base plate and against the front surface of the base plate. A transparent or translucent cover is positioned over the set of reflectors and connected to the base. Two or more display units can be connected together side by side, parallel or at an angle to one another to create displays having different heights, different widths, and different shapes. The user can easily create letters, numbers, symbols, icons or pictures through the choice and positioning of lights having different colors in the display units.

A connecting device for light emitting diode (LED) boxes and an LED display device. The connecting device for LED boxes includes: a first connecting assembly, which includes a first plugging portion; and a second connecting assembly, which includes: a fixed seat, a second plugging portion movably arranged on the fixed seat and having an extending position in a plug-in cooperation with the first plugging portion and a retracting position separated from the first plugging portion, a driving portion movably arranged on the fixed seat, wherein the driving portion is connected with the second plugging portion through a linkage device, so as to drive the second plugging portion to move between the retracting position and the extending position, and elastic reset member arranged between the fixed seat and the driving portion.

Disclosed is a display backplane, comprising a backplane, micro light-emitting diodes, a plug-in circuit board, and signal lines; a light-emitting area arranged on front surface of the backplane; a first trace area and a second trace area arranged on both opposite sides of the light-emitting area, and a third trace area arranged on one side of the light-emitting area and between the opposite sides; the third trace area is arranged between the first trace area and the second trace area; first signal lines are routed from the first trace area and the second trace area and are electrically coupled to the plug-in circuit board through the third trace area, second signal lines routed along the back surface from the first trace area and the second trace area are arranged on the third trace area in a winding manner. A display device and a tiled display device are also disclosed.

An adjusting mechanism of a box and a light emitting diode (LED) box assembly are provided. The adjusting mechanism of a box includes: a first adjusting structure which includes a first base, a rotating member, an adjusting lock hook movably arranged on the rotating member and a driving member arranged in the rotating member and driving the adjusting lock hook to move, where the rotating member can drive the adjusting lock hook to rotate when rotating such that the adjusting lock hook has a locking position and an unlocking position; and a second adjusting structure which includes a second base and an adjusting rod, where the adjusting lock hook is in the locking position when the adjusting lock hook cooperates with the adjusting rod, and the adjusting lock hook is in the unlocking position when the adjusting lock hook is separated from the adjusting rod.

A polyhedral LED display screen is provided and includes multiple cabinet main frames. Each the cabinet main frame is formed with an accommodating cavity. A side of each cabinet main frame is provided with a flexible PCB, an outer side of the flexible PCB facing away from the cabinet main frame is disposed with LED lamp beads, an inner side of the flexible PCB facing towards the cabinet main frame is magnetically connected to the cabinet main frame, and the cabinet main frames are connected to each other to form a regular dodecahedron sphere. The multiple cabinet main frames can be completely covered by the flexible PCBs, a missing display at an end point in the prior art is eliminated, design numbers and complexities of the cabinet main frames and the flexible PCBs are reduced, and an installation of the cabinet main frames becomes more convenient.

A display device and a tiled display are provided. The display device includes: a substrate having a display area and a non-display area which are defined thereon; a circuit element layer disposed on the substrate and including a conductive layer; an electrode layer disposed on the circuit element layer and including first and second electrodes spaced apart from each other; a light-emitting element disposed between the first electrode and the second electrode; and a dummy pattern disposed in a heat dissipation dummy area located at an edge of the display area. The dummy pattern includes a first layer and a second layer, the first layer is made of or includes a same material as the conductive layer of the circuit element layer, and the second layer is disposed above the first layer and in contact with at least a part of the first layer.

The present invention provides a box latch. The box latch is provided with two wedge-shaped pins symmetrically arranged around its center, and the two wedge-shaped pins are movable into a wedge-shaped notch formed by mating parts of two spliced adjacent boxes and mating with the wedge-shaped pin to lock the two adjacent boxes. The two wedge-shaped pins are symmetrically arranged around its center such that only one box latch is required to lock two adjacent boxes together, reducing the number of splicing steps and box latches, further saving manpower and material resources. In addition, the wedge-shaped pin and the wedge-shaped notch are shaped and configured to mate with each other such that self-locking occurs when they are locked, thus providing a stable connection of the boxes.
