LED electronic screen media is divided into graphic display media and video display media, which are composed of LED matrix blocks. The graphic display media can display Chinese characters, English texts and graphics synchronously with the computer; the video display media is controlled by a microcomputer, and the images and images are displayed together, and various information is played in real-time, synchronous and clear information dissemination mode, and the second display can also be displayed. Dimensions, 3D animation, video, TV, VCD shows and live live. LED electronic screen media display color is bright, three-dimensional, strong as oil painting, moving like a movie, widely used in finance, taxation, industry and commerce, post and telecommunications, sports, advertising, factories and mines, transportation, education systems, stations, terminals, airports , shopping malls, hospitals, hotels, banks, securities markets, construction markets, auction houses, industrial enterprise management and other public places.

Precautions
edit
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:
Structural design
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.
light pollution
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, there are only 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.
According to the reasons for the formation, a corresponding solution can be taken.
1. Reasonably plan the display area and installation position
According to the viewing distance and viewing angle as well as the surrounding environment, as well as the requirements of the display content, the display area and location are reasonably planned. Rather than blindly pursuing an area that is large and prominent.
2. Selection and design of playback content
Large-scale giant display screens are public media, and there are public welfare, advertising, and instructional categories. 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.
LED display products use more gray levels, making the colors look softer and the transition is natural.
4, using a system that can automatically adjust the brightness adjustment system
The brightness of the environment varies greatly at different times and places. If the display brightness of the display is greater than the environment, it will cause people's eyes to be uncomfortable, especially the difference in brightness between day and night, causing light pollution, our automatic brightness adjustment. The system can automatically convert the brightness of the broadcast suitable for the environment to avoid light pollution.
Relative neon and white light box advertising products, in recent years, many LED display manufacturers have done a lot of work in the field of needle light pollution, the degree of light pollution is greatly reduced, to enrich our visual space, to light a good life Great contribution.
Installation Precautions
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 the outer packaging of the display must be grounded, and the resistance of the grounded line should be less than 3 ohms, so that the current caused by thunder can be timely Displaced from the ground.
2, the entire screen body waterproof, dustproof and moisture-proof measures
The joint between the box and the box, and the joint between the screen and the force-mounted 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 winter, the temperature can generally reach minus ten degrees, so when choosing a circuit chip, you must choose an industrial grade chip with a working temperature of minus 40 degrees Celsius and 80 degrees Celsius to avoid the display being unable to start due to low temperature. Case.
4, the inside of the screen should be well ventilated
When the screen is energized and operated, 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, which will affect the work of the integrated circuit, which may cause burnt. The display does not work. 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.
5, the choice of highlight wick
The choice of high-brightness LED tubes allows us to display good results in direct sunlight, and it can also enhance the contrast with the surrounding environment, making the audience more wide, far away, wide viewing angle. The place still has a good performance.
