Description

Functional frame assembly for electronic signboard {Multivision frame assembly}

The present invention relates to a frame assembly for implementing a large electronic signboard by arranging a plurality of LED boards in row and column directions. More specifically, it relates to a frame assembly that accurately arranges a plurality of LED boards and creates boundaries between the LED boards. It relates to a frame assembly for an electric sign that can easily correct position to prevent damage.

In general, an electronic display board is intended to deliver various meditation information to unspecified people in a large space such as a religious facility, performance hall, or event site. It implements a large screen by closely arranging LED boards made of multiple LED pixels in rows and columns. . Here, the LED board has the shape of a flat rectangular box measuring, for example, 16cm wide and 32cm tall, and a large screen is realized by the image information distributed and transmitted to each LED board.

Typically, an electronic signboard manufactures a grid frame by welding a number of steel frames in the horizontal and vertical directions, then connects a border frame to the edge of the grid frame to complete the frame assembly, and then attaches a plurality of LEDs to the grid frame inside the border frame. It was completed by arranging the boards into rows and columns.

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

However, the frame assembly is assembled after cutting and processing a number of steel pipes to a specific length. In reality, errors occurring in the process of cutting and processing the iron pipes cause unintended steps to occur during assembly. Therefore, a step difference occurred between the multiple LED boards assembled in the stepped frame assembly, and position correction work to eliminate the step was required. This process took a lot of time and effort, leading to a decrease in assembly productivity.

In addition, in order to correct the difference between the LED boards, the process of separating or attaching a specific LED board to the frame assembly was repeated. In this process, the LED element located on the corner of the LED board was damaged. In this case, the LED board in question became defective and was discarded.

In addition, because the frame assembly was manufactured by welding, advanced welding technology and experience were required, and as a result, the quality of the frame assembly produced was inconsistent depending on the operator.

Even if multiple frames are accurately placed and then connected by welding, changes in physical properties occur during the cooling process of the welded area, causing distortion, and when multiple LED boards are arranged in a twisted frame assembly, the boundaries of the LED boards were misaligned or spread out, causing image distortion on the large screen.

The present invention was created to solve the above problems, and provides a functional frame assembly for an electric sign that can accurately arrange a plurality of LED boards and at the same time easily correct the position to prevent boundaries between the LED boards. The purpose is to
