The shortcomings of LED display screens with high navigation clearance of bridges can be summarized as follows:
1. Limited clarity:
- The clarity of LED display screens is limited by their resolution, especially when viewed at close range, mosaic phenomenon may occur, affecting the fineness and clarity of the image.
This is mainly because the resolution of LED display screens is determined by the density of lamp beads.
The more lamp beads in the same area, the higher the resolution, but even the LED display screen with the smallest spacing may not be as clear as the LCD screen.
2. Light pollution problem:
- If the brightness of outdoor LED display screens is too high, it may become one of the sources of light pollution.
This will not only have an adverse effect on the surrounding environment, but may also interfere with the vision of drivers and pedestrians, increasing the risk of traffic accidents.
Especially in special locations such as high navigation clearance of bridges, the brightness of LED display screens needs to be specially controlled to avoid interference with drivers of passing ships.
3. Stability problem:
- During long-term use, LED display screens may have stability problems such as lamp drop and dead lamp. This is mainly due to the damage or aging of lamp beads during transportation, installation and use. These problems will not only affect the display effect of the display, but may also increase the subsequent maintenance costs.
4. Viewing angle limitation:
- The viewing angle of the LED display is relatively small, and it needs to be viewed within a certain angle range to obtain the best visual effect. In the location of high navigation clearance of the bridge, if the installation angle and position of the display are improper, the audience in some areas may not have a clear viewing experience.
5. High requirements for heat management:
- The LED display will generate a certain amount of heat during operation. If the heat management is not proper, it may affect the service life and display effect of the display. In outdoor environments such as high navigation clearance of bridges, factors such as temperature changes and wind force may affect heat management, so special attention needs to be paid.
6. High price:
- Compared with other display technologies, the price of LED displays is usually higher. This is mainly due to factors such as its complex manufacturing process, high material cost and large market demand.
In special application scenarios such as high navigation clearance of bridges, if the budget is limited, other more economical display solutions may need to be considered.
In summary, the disadvantages of high-clearance LED displays for bridge navigation mainly include limited clarity, light pollution, stability, viewing angle limitations, high requirements for heat management, and high prices.
When selecting and using LED displays, these factors need to be fully considered to ensure that they can meet actual needs and achieve the best results.
