What a company seeks is nothing more than long-term profitability and maximization. However, the fierce competition in the industry and the price reduction of customers have led to a significant profit in the LED industry, including LED displays .
　　 The LED display is divided into single color, double primary color, three primary colors ( full color ) , four primary colors (RGB+ yellow Y) , and five primary colors (RGB+ cyan G+ yellow Y) according to color . At present, most of the commercial advertisements use three-color full-color display screens. The four primary colors are used less in view of cost, and the five primary colors are still in theory.
　　 The illuminating material of the LED display itself is energy-saving, but considering the application display area is relatively large, long-time operation and high-brightness playback, the power consumption can not be underestimated. In addition to the cost associated with the LED display itself, the advertising cost will also increase geometrically with the use of the device.
Energy-saving LED display adopts high-efficiency and low-power chip design, adopts high-efficiency switching power supply of half bridge or full bridge from power supply, and reduces power supply voltage as much as possible under the state of constant current of driving IC . The blue dies are separately powered to achieve better energy savings.
In addition to the above methods, it is also possible to use a backlight design to save energy by automatically adjusting the brightness of the LED display . Of course, wind-solar complementary LED display , solar display, etc. are all good choices.
How can an LED manufacturer continue to grow bigger and stronger in the fierce competition? It is undoubtedly a matter of suppressing the thirst by simply fighting the price war. Only by starting with technological improvement and innovation can we go farther than other companies.
