Outdoor media LED display is one of the important trends in the development of the advertising industry in recent years.
As an outdoor advertising display device with audio and video functions, it has become an indispensable part of urban public spaces.
The following is a detailed introduction to the outdoor media LED display, which will cover its definition, characteristics, applications, technical details and other aspects.
Definition and Overview
Outdoor media LED display is usually installed on the roof of a building, in front of a commercial area, on the roadside and other outdoor venues for publishing advertising information.
It is a display that uses LED (light-emitting diode) as a light-emitting element and realizes full-color display through a combination of three primary colors: red, green and blue.
Outdoor media LED display has the characteristics of high brightness, wide viewing angle and bright colors. It can clearly display images and text in the sun, providing strong support for the dissemination of advertising information.
Features and Advantages
- High brightness: The brightness of the outdoor media LED display is much higher than that of traditional outdoor billboards. Even in direct sunlight, it can ensure that images and text are clearly visible.
- Large viewing angle: The viewing angle of the LED display can reach more than 140 degrees, and the audience can see the complete picture in a wider range.
- Bright colors: LED is used as the light-emitting element to achieve full-color display, with bright colors, high contrast and more shocking visual effects.
- Energy saving and environmental protection: LED display screens have low energy consumption and long service life, which conforms to the energy-saving and environmental protection concept of modern society.
- Programmable control: Outdoor media LED display screens can be programmed and controlled by computers to achieve multiple playback modes and special effects, which improves the dissemination effect of advertising information.
Application
Outdoor media LED display screens are widely used in finance, taxation, industry and commerce, post and telecommunications, sports, advertising, factories and mines, transportation, education systems, stations, docks, airports, shopping malls, hospitals, hotels, banks, securities markets, construction markets, auction houses, industrial enterprise management and other public places.
It can not only be used for the dissemination of commercial advertisements, but also for the release of public information, traffic induction and other aspects.
Technical details
- Display screen structure: Outdoor media LED display screens are usually composed of display unit boards (modules), control systems, power supply systems, heat dissipation systems, waterproof and dustproof systems, etc. Among them, the display unit board is the core part of the LED display screen. It is composed of multiple LED lamp beads, which display images and texts by controlling the brightness of the lamp beads.
- Display principle: The display principle of LED display is to control the current and voltage of LED lamp beads to make them emit light of different colors and brightness, and then realize full-color display through the combination of red, green and blue three primary colors. At the same time, by controlling the on and off time and sequence of the lamp beads, dynamic display of images can be realized.
- Control system: The control system of outdoor media LED display is usually controlled by microcomputer, which can realize the playback effect of text and images. The control system can also automatically adjust the brightness of the display according to the changes in ambient light to save energy and improve the display effect.
- Waterproof and dustproof system: Since outdoor media LED display needs to work in outdoor environment for a long time, it must have waterproof and dustproof functions. Waterproof glue, sealing strips and other materials are usually used to seal the display to prevent moisture and dust from entering the inside of the display and affecting its normal operation.
Development trend
With the continuous advancement of science and technology and the continuous growth of market demand, the development of outdoor media LED display shows the following trends:
- High definition: With the continuous advancement of display technology, the resolution of outdoor media LED display is constantly improving, realizing high-definition display. High definition not only improves the clarity and color reproduction of the picture, but also makes the dissemination of advertising information more vivid and realistic.
- Intelligence: With the development of technologies such as the Internet of Things and big data, outdoor media LED displays are gradually becoming intelligent. Intelligent displays can monitor environmental parameters and audience behavior in real time through sensors and other devices to achieve adaptive playback and precision marketing.
- Energy saving and environmental protection: Energy saving and environmental protection are the inevitable trend of future development. Outdoor media LED displays will continue to improve energy efficiency and reduce energy consumption, adopt more environmentally friendly materials and manufacturing processes, and reduce the impact on the environment.
- Diversification: The application areas of outdoor media LED displays will be more extensive. In addition to the traditional commercial advertising field, it will also expand to smart cities, cultural tourism, sports events and other fields.
FAQs about outdoor media LED displays
The LED display cannot read the program content in the USB flash drive.
- Check whether the USB flash drive or USB extension cable has poor contact, and ensure that the USB extension cable is of moderate length, generally not more than 5 meters.
- Check the control card voltage, which is generally around 5V. USB flash drives of different brands may have different voltage requirements. You can try to power off and restart and reinsert the USB flash drive.
- Format the USB flash drive (format FAT/FAT32), re-export the program, and then insert it into the control card.
- Try to replace the USB flash drive. It is recommended to use brands such as Sandisk and HP.
- Check whether there are multiple mobile devices plugged into the computer to ensure that the program has been exported to the USB flash drive to be inserted into the control card.
The brightness of the outdoor LED display is insufficient or too high.
- Adjust the brightness of the LED display according to the ambient brightness to ensure the best visual effect under different lighting conditions. For example, the brightness requirement of outdoor LED display screens (facing north and south) is usually greater than 8000CD/M2.
- Check the OE polarity setting to ensure that the brightness of the display screen is normal. If the OE polarity setting is incorrect, the display screen may be very dim or have ghosting.
The LED display screen may not work properly, which may be manifested as the green light of the sending card flashing or not flashing.
- Check the power connection to ensure that the screen is powered normally.
- Check the network cable connection to ensure that the network connection is good.
- Check the power supply and voltage of the receiving card to ensure that the voltage is stable.
- Try to replace the sending card to eliminate the possibility of sending card failure.
- Check the signal transmission equipment (such as function cards, fiber optic transceiver boxes, etc.) to ensure that the equipment is connected and working properly.
The LED display screen has abnormal phenomena such as flower spots, distorted images, and the same display unit content.
- Check the driver loader to ensure that the program is loaded correctly.
- Check the network cable connection between the computer and the display to ensure that the network cable is of moderate length and good quality.
- Try to replace the sending card to eliminate the possibility of sending card failure.
- Check the display connection file to ensure that the correct connection file has been sent and the connection is correct.
- Adjust the function card settings to ensure that the settings are correct to solve the problem of image blur or brightness.
