With the popularization and application of LED electronic display screens and LED full-color screens, LED display screens have become a beautiful landscape in today's information society. Especially at night, LED display screens are blooming and people can feel the world. Colorful and colorful.

    LED display outdoor installation

    Outdoor LED billboards have the advantages of good stability, low consumption, and wide range of radiation, and they are the most suitable products for outdoor information dissemination. Basically, common LED displays include advertising screens, text screens, graphic screens, and so on, which are also the first choices for urban life and brightness.

    Then, when constructing such high-quality LED advertisements in the outdoors, what specific factors should be taken care of? I believe that these contents are the topics most concerned by everyone, especially for some technical construction workers, knowing that outdoor construction and maintenance of advertising screens will effectively promote Business advertising, information dissemination.

    I. Field survey

    This refers to the test of the specific environment, topography, radiance range, brightness acceptability and other parameters before the installation of outdoor LED displays. To ensure the smooth installation of billboards, it is necessary to The commander conducted a unified lifting program to ensure that the equipment can be used normally and stably.

    Second, LED equipment construction

    When constructing outdoor LED billboards, it is necessary to distinguish between wall advertising screens, hanging advertising screens, and roof-top advertising screens. In the actual installation, all cranes and hoists should be used to lift the parts according to the distance. At the same time, ensure that the above personnel cooperate with each other. For a high-altitude LED advertising screen, there is a better installation process.

    Third, the luminous radiation range debugging

    Next, we must conduct a specific radiation range detection, due to different radiation range, LED display structure is not the same perspective, according to the field acceptance capabilities and normal viewing angle range of outdoor LED display installation work to ensure that every angle Looking from afar, you can see normal, well-balanced images and subtitle information.

    LED display fault detection

    With the continuous expansion of the LED display applications, LED display problems appear more and more problems, then in the end how to test the LED display fault? Here's a brief introduction for everyone.

    1. Resistance detection method: Adjust the multimeter to the resistance file, detect the resistance value of a certain point of a normal circuit board to the ground, and then test whether the same point of the same circuit board is tested with the normal resistance value. If it is different then the scope of the problem is determined.

    2, voltage detection method, the multimeter is transferred to the voltage file, to detect the voltage of the point of doubt of the circuit of a certain point to the ground, compare whether it is similar to the normal value, otherwise determine the scope of the problem.

    3, short-circuit detection method, the multimeter will be transferred to the short-circuit detection block (some diode downshift or resistance file, generally with alarm function), the detection of whether there is a short circuit phenomenon, found that short-circuit should be given priority to solve, so that it does not burn out Other devices. This method must be operated with the circuit powered down to avoid damage to the watch.

    4, pressure drop detection method, the multimeter to the diode drop detection file, because all of the IC is composed of many basic units, but miniaturized, so when there is a current through a pin, There will be a voltage drop on the pin. Generally, the voltage drop on the same pin of the same type of IC is similar, and the voltage drop on the pin is better or worse, and the circuit must be operated with the power off. This method has certain limitations. For example, if the device under test is high-impedance, it cannot be detected.

    Subsequent inspections, including many areas, such as LED display waterproof, heat dissipation layer, LED waterproof coating, the display area above the rain, both sides of the cooling empty, power supply lines, etc., these basic parts products constitute the entire stability Good graphic LED display, late technical maintenance, it is necessary to carry out a unified management and maintenance of these components, encountered product rust, instability, damage, the need for timely replacement to ensure the safe use of the entire display.
