How can LED backlight and high brightness LCD screens achieve true energy conservation? To reduce the power consumption of LED displays, we need to address the following issues:
1. The working voltage of LED lights is very low, usually between 2-3.4V DC. Therefore, it is necessary to use a switching power supply to convert the high-voltage AC power of the mains. How to achieve the highest conversion efficiency during the conversion process;
2. The working voltage of ordinary LED display module is usually 5V DC, while the working voltage of LED is 2-3.4V. How to effectively improve the circuit to minimize the voltage of the driving circuit, reduce the loss of voltage on the circuit, thereby reducing unnecessary heat loss and reducing power loss;
3. How to improve the photoelectric conversion efficiency of LED, while ensuring the brightness of the display screen, to reduce the driving current and ultimately achieve the goal of saving electricity; How to use the brightness of the display screen correctly, so that the brightness can change with the environment and save electricity.
Regarding the above issues, manufacturers of high brightness LCD screens would like to share some suggestions with everyone:
1. Adopting high luminous efficiency LED, the luminous chip does not cut corners;
2. Adopting high-efficiency switching power supply, greatly improving power conversion efficiency;
3. Design excellent screen heat dissipation to reduce fan power consumption;
4. Design a scientific overall circuit scheme to reduce internal circuit power consumption;
5. Automatically adjust the brightness of the outdoor high brightness display screen according to changes in the external environment.
