ما تسعى إليه المؤسسة ليس أكثر من - فائدة وتعظيم على المدى الطويل. ومع ذلك ، أدت المنافسة الشرسة في الصناعة وخفض الأسعار من قبل العملاء إلى تحقيق أرباح غير كبيرة لصناعة LED ، بما في ذلك شركات شاشات العرض LED.
The light-emitting material of the LED display itself is energy-saving, but considering the application and display area is relatively large, long-term operation and high-brightness playback, the power consumption should not be underestimated. In addition to the cost associated with the LED display itself, advertising owners will also increase the electricity bill geometrically with the use of the device. How to use the LED screen to achieve the effect of energy saving? The LED screen has a contrast ratio of brightness. When we use the LED screen, we don't need to use the light-sensing response. During the day, the brightness of the LED screen can be higher, and the brightness at night can be lowered a little, so that our LED screen saves skills. Electricity can also meet the needs of customers twice with one stone.
The energy-saving LED display adopts high-efficiency and low-power chip design, and uses a half-bridge or full-bridge high-efficiency switching power supply from the power supply to reduce the power supply voltage as much as possible under the constant current state of the driver IC. , The blue chips are powered separately to achieve better energy-saving effect.
The LED display screen is divided into single color, double primary color, three primary color (full color), four primary color (RGB plus yellow Y), and five primary color (RGB plus cyan G plus yellow Y). At present, most of the commercial advertisements use three-color full-color display screens. Four-primary colors are less used in view of the cost, and five-primary colors are still in theory. 1584585421520442.jpg
In addition to the above methods, the backlight design can also be used to save energy by automatically adjusting the brightness of the LED display. Of course, the selection of driving ICs for wind-solar hybrid LED displays and LED screens can also achieve energy-saving effects for LED screens. The ICs of LED screens are divided into ordinary ICs, energy-saving ICs, and high-brush ICs. In addition, some businesses now use solar energy storage to drive LED screens, which is also a good method.
