First, outdoor LED display:
The area is generally tens of square meters to several hundred square meters or even larger, the brightness is high, the viewing angle is large, and it can work in the sun, and has certain windproof, rainproof and waterproof functions. Mainly used for outdoor advertising, stations, squares, shopping malls, etc.
Outdoor LED displays usually appear in the form of outdoor media. Outdoor media refers to the medium for advertising information on the roof of major buildings and the outdoor venues in front of the commercial area, such as road LED display, LED electronic display, LED full color screen, LED screen. , balloons, airships, cars, large inflatable models, etc.
Outdoor LED display use note
With the continuous development of urban construction, outdoor LED displays are increasingly used as new media for advertising media. The outdoor LED display can definitely bring a certain improvement to the image of the city, and the form of advertising is flexible. However, during the use of outdoor LED displays, there are still some things to note:
Outdoor LED displays are generally large in size, so they are still very heavy. Installed in the outdoor LED display, the home page needs attention is the structural design. The installation structure should take into account: wind, earthquake, load and other major factors; secondly, the shape, structure, and exterior design of the screen should be coordinated with the building or environment to which it depends; in addition, consider local environmental factors, such as Air humidity, air salt and alkali content (seashore city) and so on.
With the popularity of LED displays, the concept of “light pollution” has been raised. So in the end, is the LED display considered "light pollution"? The international definition of light pollution is usually divided into three categories: white bright pollution, artificial chalk and color light pollution. At present, China only has regulations on the glass curtain wall in Bailiang pollution, and there is no relevant regulation on artificial chalk and color light pollution. However, considering that color light pollution does cause people to feel uncomfortable, it should belong to "light pollution." The problem of light pollution prevention of the display screen has been considered in designing the display screen.
Second, led outdoor advertising screen how to install
1. Reasonably plan the display area and installation position According to the viewing distance and viewing angle and the surrounding environment, as well as the requirements of the display content, the display area and position are reasonably planned. Rather than blindly pursuing an area that is large and prominent.
2, the choice of playback content and design large-scale giant display is a public medium, there are public welfare, advertising, instructions and so on. When we choose to play the content, we must agree with the public request to avoid refusal. 3, multi-level gray correction technology to improve color softness.
Outdoor led advertising screen installation steps
Led display installation step 1: outer frame splicing Assembling the outer frame of the led display, that is, splicing the cut profiles, the general profiles on the market mainly have square and round points, but the assembly method is the same.
Led display installation step two: fixed unit board
1. Place the unit board in the frame (note the front and back sides of the frame, the grooved side is the front side). At this time, the position of the mounting strip must be quite accurate, otherwise it should be reinstalled from the beginning.
2. After the back strip is fixed, you can remove the frame and start installing the magnet.
3. After the magnet is installed, close the frame and let the magnet and the back strip suck. The fixing work of the unit board is completed.
Led display installation step three: connect the cable and the upper and lower power cables
Led display installation step four: fixed power supply and control card Power and unit board wiring, need to pay attention to the positive and negative, it is recommended to use SVV2 * 1.0 soft core wire, which is 1 square double strand soft core wire.
Led display installation step 5: control card and unit board cable connection (especially important) Please carefully read before connecting, the screen is not fixed to the wall, this is the most critical step, you can first check the screen installation through the test button.
Third, led outdoor advertising screen installation notes
1. Lightning protection measures for installing buildings and screens In order to protect the display from strong electromagnetic attacks caused by lightning, the screen and outer packaging of the display must be grounded, and the resistance of the grounded lines should be less than 3 ohms. In this way, the current caused by thunder can be drained from the ground in time.
2. Waterproof, dustproof and moisture-proof measures for the entire screen body. The joint between the box body and the box body, and the joint between the screen body and the force-mounting object should be seamlessly connected to avoid water leakage and moisture. In the interior of the screen body, it is necessary to have good drainage and ventilation measures, and if there is water in the interior, it can be treated in time.
3, on the choice of circuit chips in the northeast of China, the temperature in winter can generally reach minus ten degrees, so when choosing a circuit chip, you must choose the industry with a working temperature of minus 40 degrees Celsius and 80 degrees Celsius The chip is used to avoid the situation that the display cannot be started due to the low temperature. 4, the inside of the screen should be well ventilated. When the screen is energized, it will generate a certain amount of heat. If the heat is not discharged, if it accumulates to a certain extent, the internal environment temperature will be too high, and the work on the integrated circuit will be caused. The impact is severe, which can lead to burnout, and the display cannot run. Therefore, it is necessary to do the ventilation and heat dissipation measures inside the screen body, and the temperature of the internal environment is kept between minus 10 degrees and 40 degrees.
The choice of high-bright wicks has chosen a high-brightness LED tube, which allows us to display good results in direct sunlight, and also enhances the contrast with the surrounding environment, making the audience of the picture wider and wider. Far away, where the perspective is wide, there are still good performances.
