Indoor full-color LED display screens have the following advantages in terms of energy saving: - **Efficient electro-optical conversion**: Using light-emitting diodes as light sources, its electro-optical conversion efficiency is high, and it can convert almost all electrical energy into visible light. Compared with traditional cathode ray tube (CRT) display screens and some liquid crystal display screens, the power consumption at the same brightness is greatly reduced, which can effectively save a lot of power resources and reduce operating costs. - **Energy-saving control technology**: It has a variety of energy-saving control technologies, such as intelligent brightness adjustment, automatic sleep/wake-up, energy-saving mode and other functions. The brightness and power consumption of the display screen can be automatically adjusted according to the ambient light and usage conditions. PWM dimming technology, energy recovery technology and other technologies can also be used to optimize power management, reduce energy loss and waste, and further improve energy utilization. - **Low-power display characteristics**: When displaying black or dark scenes, the LED display screen can greatly reduce the brightness, that is, reduce power consumption, while traditional displays still consume more energy when displaying dark colors such as black. - **Environmentally friendly materials and manufacturing**: Environmentally friendly materials are mostly used in the production process, and they do not contain harmful substances such as mercury and lead, which reduces pollution to the environment. Moreover, when it is disposed of, it is less harmful to the environment than traditional display screens containing toxic substances such as heavy metals, and is in line with the environmental protection concept of sustainable development.
