Nowadays, with the rapid development of the display market, outdoor LED displays have become a hot product in the industry. With advantages such as high brightness and high refresh rate, they have quickly replaced traditional billboards and become outstanding players in the outdoor LED screen category. Although outdoor LED displays have many advantages, those who have used them know that they inevitably suffer from light pollution problems. So, do you know how to effectively reduce the light pollution of outdoor LED displays? Below, HSC LED will introduce you to methods for reducing the light pollution of outdoor LED displays.
As the ambient brightness is lower at night, the brightness of the outdoor advertising LED display can be reduced at night through brightness adjustment technology, and restored to the design brightness during the day. This not only does not affect the effect of the LED screen but also reduces nighttime light pollution and saves electricity.
Large and giant screens are public media, including public welfare, advertising, guidance, and so on. When choosing content to play, it must be in line with public requirements and avoid rejection.
Reasonably distribute the light of the outdoor advertising LED display within the visible range of the human eye, uniformly diffuse the light energy output by the display screen, and avoid the problem of partial strong light. This requires strict specifications for the direction and scope of light irradiation during the production of outdoor advertising LED displays to effectively control light pollution.
Due to the complexity of human visual perception, it is difficult to reflect human perception of light through the measurement standard of brightness alone. Therefore, the irradiance index can be introduced as a standard for judging the visible light safety energy range. When measuring the effect of light on human eyes, it is necessary to introduce an irradiance meter to objectively reflect the impact of blue light output intensity on visual perception. The factory of outdoor advertising LED displays should appropriately reduce the output of blue light while ensuring the display function of the screen, so as to avoid discomfort to the human eye.
Outdoor advertising LED display products use more grayscale levels to make colors look softer and transitions more natural.
Adopt a brightness adjustment system that can be automatically adjusted by the system
The brightness of the environment changes greatly at different times and places. If the playback brightness of the outdoor advertising LED display is too high relative to the environment, it will cause discomfort to people's eyes, especially when there is a significant difference in brightness between day and night, resulting in light pollution. Our automatic brightness adjustment system can automatically calculate the suitable playback brightness for the environment, avoiding light pollution.
Reasonable planning of display area and position based on viewing distance, viewing angle, surrounding environment, and content requirements, rather than blindly pursuing oversized or prominent areas.
These are the methods for reducing the light pollution of outdoor advertising LED displays. Compared with neon lights and white light box advertisements, many outdoor advertising LED display manufacturers have done a lot of work to reduce light pollution. The degree of light pollution has been greatly reduced. Generally, the playback brightness of outdoor advertising LED displays does not exceed 60% of the ambient brightness, which limits the stimulation of the human eye and can greatly reduce light pollution in the environment. So, there is no need to worry too much about light pollution. If you want to learn more about LED display products, please contact us immediately.
