How to make LED display screen more energy-saving and environmentally friendly
Jul.24.2025
- With the continuous development of science and technology, LED display screens have been widely used in life. However, not everything is as people wish. LED display screens often have environmental problems during use. So, what are the main advanced technologies of LED display screens in energy saving and environmental protection?
- 01
- Adopt an adjustment system that can automatically adjust the brightness
- Depending on the day and night, in different locations and time periods, a slight change in the brightness of the display screen will produce a great effect. If the playback brightness of the LED display screen is greater than 50% of the ambient brightness, we will obviously feel eye discomfort, which will cause "light pollution".
- Then we can use the outdoor brightness collection system to collect the ambient brightness at any time, and use the display control system to receive system data and automatically convert it into a brightness suitable for the environment through software to play the picture.
- 02
- Adopt products with multi-level grayscale correction technology
- Ordinary LED display screen systems use 18-bit color display levels, so in some low grayscale and color transitions, the color will be displayed very stiffly, which will cause color light discomfort. The new LED large-screen control system uses a 14-bit color display level, which greatly improves the hardness of the color in transition, making people feel soft colors when watching, and avoiding people's discomfort with light.
- In terms of power consumption, although the luminous materials used in the LED display screen itself are energy-saving, some need to be applied in occasions with a large display area. Due to long-term use, the overall power consumption is still large because it requires a relatively high brightness. Under the influence of these comprehensive factors, the power consumption of the display screen is quite amazing, so the electricity bills borne by advertising owners will also increase geometrically.
- Therefore, it is also necessary to use more advanced processing technology to save resources and energy.
- A. By using high-efficiency LEDs, the luminous chips do not cut corners;
- B. Use high-efficiency switching power supplies to greatly improve the power conversion efficiency;
- C. Perform excellent screen heat dissipation design to reduce fan power consumption;
- D. Design a scientific overall circuit solution to reduce internal circuit power consumption;
- F. Automatically adjust the brightness of the outdoor display screen according to changes in the external environment, thereby achieving energy saving and emission reduction effects
