Description

Folio LED display

The invention relates to a split-type LED display screen, in particular to a display module structure which can be split or combined to increase the size through a combination of splitting or pairing through a track.

In general, such as public places, department stores or public institutions, in order to achieve the effect of expanding the display, most of the display units are stacked into a display screen (such as a TV wall or kanban type). The use principle of this large display screen That is, multiple display units are stacked and assembled, so that the overall size can be increased to the size of a TV wall or a signboard, and then a signal integration device is used to convert the input signal to different positions according to the number of display units. Display unit, so that the pictures displayed by the display units at different positions can be spelled into a complete picture, so as to achieve the purpose of image size enlargement.

In order to match the playback effect or venue requirements, multiple displays can also be connected to form a larger display. At present, only the displays are attached, but the effect of the attachment is not very tight, resulting in various There are obvious joint lines between the displays, especially in the state of playback, so it will affect the quality of playback.

Therefore, in order to maintain the tightest and seamless sealing state of each display screen, the driving motor continues to pressurize the display screens after they are attached, so that the display screens can be maintained at the tightest adhesion. State, and let the display screens be suspended in a V-shape with high inside and low outside. During lamination, the inside edges between the display screens are tightly closed from bottom to top, and two can be maintained to maintain the display screens. In the tightest state, this is the solution of the invention.

The split LED display screen of the present invention includes a stroke control module and a display module, the stroke control module has a track, at least one drive motor is installed beside the track, and at least one is electrically connected to the drive motor The travel controller; and the display module has two symmetric display screens, at least two inner suspension pieces and an outer suspension piece are fixed on the upper two ends of the display screen respectively, and the inner suspension piece The length of the outer suspension is smaller than that of the outer suspension, so that the inner horizontal position of the two display screens is higher than the outer horizontal position. The inner suspension and the end of the outer suspension are pivotally connected to a conveying member, each of the conveying members It is installed on the track; by this, the conveyor must be controlled by the drive motor to move on the track, so that the two inner sides of the display screen are attached to each other After closing, the stroke controller can keep the drive motor running and maintain the pressurized state, so that the two display screens are maintained in the tightest tight state.

More specifically, the drive motor system uses a DC brushless motor, and a stepper motor is the best.

More specifically, the display screen has an outer frame, and a plurality of vertical frame bodies are fixedly arranged in the outer frame, and an average array of a plurality of unit lamp boards is arranged on each of the vertical frame bodies.
