At present, the interactive floor LED displays screen is applied in the fields of staging, curtain walls and commercial exhibitions. For non-professionals, when they need clear LED display, they worry about low quality products and don’t know how to choose. As below, the standard tests were conducted by Guojia Optoelectronics
Screen Detection
Visual inspection and hand touch can be used as a first step to understand if there is a problem with the main body;
The screen cover has no separation parts;
The screenshot has no color cast, no death, etc.
The distance of the LED balls from the screen body is clean and uniform, and there are no irregularities. The joint gap error is within 0.2 mm.
The color corresponds to the sample. In natural light, such as a fluorescent lamp, no apparent chromatic aberration is observed. The same batch of products has no color difference, and the surface of the coating is smooth, uniform and uniform.
The detection of the cabinet panel
There are many detection methods to check the cabinet. Commonly used tools are vernier caliper, tape measure, leveling tool. It requires inspectors to check very strictly one by one according to designers’ drawings whether any parts are missing one by one.
The deviation of the outer dimensions of the transparent LED screen box is not more than 0.5mm, and the difference between the two diagonal lines is not more than 1mm;
Check that the burr has been removed, that the sharp corner is obtuse and that it is not allowed to scratch or stab with the hands
Each nut and column nut should be machined with the back-to-tooth treatment to ensure that the screw can be locked smoothly;
Check whether the general cabinet mounting requirements have been worked out according to the drawings. All accessories (such as locks and hinges) must be made with existing standard parts. Mechanical strength and sealing must be ensured during assembly.
The soldering of each box connection must be firm, with no virtual solder marks or dispersion soldering.
After welding, the drilling of the hole in the LED module and the flatness of the front must be guaranteed. The surrounding panels should not be bent or warped. The flatness error is less than 1 mm. The size of the positioning hole on the front panel of the cabinet is strictly controlled. The size of the opening and the space of the hole. The error is less than 0.1mm, and the X and Y directions of the group holes should be on the same straight line, and the straight line should be perpendicular to the edge of the box, respectively, and the perpendicularity is less than 1mm .
The future of the transparent LED screen
Interactive floor LED displays, also called LED glass screen, is mainly used for architectural glass curtain wall. It is used to display high definition screens. It is characterized by high transparency and ultra-light weight. The traditional LED display is installed on the outside wall of the building and completely blocks the outside light. The weight of the main body of the screen verifies the safety of the building itself and can also affect the appearance of the building. The integration of the transparent LED display with the appearance of the building does not detract from the original style and lighting of the building. Ultra-light and ultra-sleek have gained a huge advantage over the traditional media field.
Along with the proliferation of outdoor LED displays, it has created a number of negative problems, including the image of the city. When the LED display works, it will illuminate the city and release information. However, when it is “quiet”, it seems to be a “scar” of the city, which is incompatible with the environment and negatively affects the beauty of the city.
As a result of these problems, the approval of large screen outdoor installations has become increasingly cumbersome and the management of outdoor advertising has become stricter.
The interactive floor LED displays not only integrate all the benefits of a conventional outdoor HD LED display, but also minimizes the negative effects on urban aesthetics. Because it is installed indoors behind a glass curtain wall and will not harm the environment even if it does not work during the day. At the same time, it adopts a new form of outdoor advertising, bypassing the adoption of outdoor advertising.
