With the continuous development of urban construction, outdoor LED displays are increasingly being used as a new advertising medium. Outdoor LED displays can indeed enhance the city's image, and the advertising formats are flexible and diverse. However, there are still some precautions to take when using outdoor LED displays:
Structural Design
Outdoor LED displays are generally large in area, making them quite heavy. The first thing to consider when installing an outdoor LED display is its structural design. The installation structure should consider factors such as wind resistance, earthquake resistance, and load-bearing capacity. Secondly, the shape, structure, and exterior decoration of the screen should be coordinated with the building or environment it is attached to. Thirdly, local environmental factors should be considered, such as air humidity and air salinity (in coastal cities).
Light Pollution
With the popularization of LED displays, the concept of "light pollution" has emerged. So, does an LED display constitute "light pollution"? Internationally, light pollution is generally defined into three categories: glare pollution, artificial daylight pollution, and colored light pollution. Currently, my country only has regulations for glass curtain walls (glare pollution), and there are no regulations for artificial daylight pollution and colored light pollution. However, considering that light pollution does cause discomfort, it should be classified as "light pollution." Therefore, the design of display screens must take into account the prevention and control of light pollution.
Based on the causes, corresponding solutions can be adopted.
1. Rationally plan the screen area and installation location.
Based on viewing distance, viewing angle, surrounding environment, and the requirements of the displayed content, the display area and location should be rationally planned, rather than simply pursuing a super-large area and a prominent location.
2. Selection and design of playback content. Large-scale giant displays are public media, including public service announcements, advertisements, and directional displays. When selecting playback content, it is essential to ensure consistency with public expectations and avoid viewer aversion.
3. Multi-level grayscale correction technology improves color smoothness.
LED display products utilize more grayscale levels, making colors appear softer and transitions more naturally.
4. Employs an automatically adjustable brightness system. Brightness varies greatly depending on the time and location. If the display screen's brightness exceeds the ambient light level significantly, it can cause eye strain, especially during the day and night when brightness differences are substantial, resulting in light pollution. Our automatic brightness adjustment system automatically calculates the appropriate display brightness for the environment, avoiding light pollution.
Compared to neon lights and white light box advertising products, many LED display manufacturers have made considerable efforts to reduce light pollution in recent years, significantly lowering its levels and making a significant contribution to enriching our visual space and illuminating our lives.
