Frame assembly for electric signboard {Multivision frame assembly}

The present invention relates to a frame assembly for an electric signboard for arranging a plurality of LED boards in row and column directions, and more particularly, to a frame assembly for an electric signboard, which can accurately arrange a plurality of LED boards so that no boundary is generated between them. it's about

In general, an electronic display board is for conveying various meditation information to unspecified people in a large space such as a religious facility, concert hall, or event site, and a large screen is implemented by closely arranging an LED board composed of a plurality of LED pixels in rows and columns. Here, the LED board has the shape of a flat rectangular parallelepiped box having a size of, for example, 16 cm in width and 32 cm in length, and a large screen is implemented by the image information distributed and transmitted to each LED board.

In a typical electronic display board, a grid frame is manufactured by welding a plurality of steel frames in the horizontal and vertical directions, and then a frame assembly is completed by connecting a frame frame to the edge of the grid frame, and then a plurality of LEDs are attached to the grid frame inside the frame frame. It was done by arranging the boards in rows and columns.

On the other hand, since the LED board is formed by arranging thousands of LED pixels in rows and columns, and image information is distributed to each LED board to form a unit screen, each LED board must be arranged in rows and columns in exactly right angles. do.

However, since the frame assembly is manufactured by connecting a plurality of steel frames by welding, a high degree of welding technology and experience are required, and accordingly, the quality of the frame assembly manufactured according to the operator is not constant.

In addition, even if a plurality of frames are accurately arranged and then welded, a distortion occurs due to a change in physical properties while the welded area is cooled, and when a plurality of LED boards are arranged in a distorted frame assembly, the boundary of the LED board Image distortion occurred on a large screen that was implemented by being misaligned or widened.

In addition, in order to correct image distortion, a position correction operation to accurately match the boundaries of a plurality of LED boards was required, and a lot of time and effort were required in this process, leading to a decrease in assembly productivity.

The present invention has been created to solve the above problems, and it can be manufactured without welding, and a plurality of LED boards can be arranged accurately in rows and columns, so that correction work can be omitted. is intended to provide
