How can led display screen save energy?

With the rapid development of society, all walks of life are also advocating the manufacture of green products, and the LED industry is no exception. LED display screen has been widely used on all street corners of the city and has become a unique symbol to enhance the city’s image and beautify the city image. The LED industry should keep pace with the times, respond to the national call, and promote energy-saving and environmental protection products. As we all know, an LED display screen may not achieve the ideal effect in energy saving because of its high brightness, but this does not mean that it must be a high energy consumption product. So how can a led display screen be more energy-saving?

energy-saving led screen

  • Choose environmentally friendly materials

The LED display screen made of environmental protection materials can achieve the purpose of waterproof, dustproof, and ultraviolet radiation without glue filling after special processing technology. Compared with the products produced by the general process, it has fewer consumables and is more environmentally friendly.

  • The adjustment system with automatic brightness adjustment is adopted

Day and night, in different places, environments, and time periods, a slight change in the brightness of the display screen will have a great effect. If the brightness of the LED display screen is 50% higher than the ambient brightness, we will obviously feel uncomfortable with our eyes, which will cause light pollution.

We can collect the ambient brightness at any time through the outdoor brightness acquisition system, and use the display control system to broadcast the picture by receiving the system data and automatically converting it into the brightness suitable for the environment through software.

  • Constant current noise reduction technology

The LED display driving chip adopts the internationally advanced LED display special chip system, which is a leading manufacturer in the field of full-color LED display. Combined with the characteristics of the chip, the constant current noise reduction technology is studied and formed to ensure that the influence of other noise source factors such as power supply on the LED electronic display screen is reduced to a very low level. Some drive ICs can also save the original 5V voltage to 4.2V to achieve the function of energy-saving.

  • Multilevel gray correction technology

Ordinary LED display system adopts an 18bit color display level, so that in some low gray and excessive colors, the color will be displayed very stiff, so it will cause the maladjustment of color light. The new LED large screen control system adopts a 14bit color display level, which greatly improves the hardness of color in excess, makes people feel soft color when watching, and avoids people’s discomfort with light.

  • A strong convection heat removal system makes the heat dissipation system stable

The LED display screen will release more heat after working for a long time. If the heat is not released in time, it will cause a certain degree of damage to the screen body and affect the normal use of the screen. In order to ensure the normal operation of the display screen in a stable environment, it is necessary to strengthen the heat dissipation system of the LED display screen.

  • Power supply

The realization of LED energy-saving display screens mainly starts from the power supply. Half-bridge or full-bridge high-efficiency switching power supply is directly adopted on the existing LED display screen, coupled with synchronous rectification, which has a remarkable energy-saving effect. Reduce the power supply voltage as much as possible under the condition of constant current to the driving IC, and achieve a better energy-saving effect by supplying power separately through each tube core of red, green, and blue.

If the selection of LED display screen can start from six aspects: material selection, brightness adjustment, noise reduction treatment, heat dissipation improvement, and power supply, then led display screen can also make its own efforts for energy conservation and environmental protection.
