many led display companies in the industry have been involved in the production process of energy saving and emission reduction. at present, some energy-saving led display screens on the market, mainly through the improvement of power supply to improve energy-saving effect, attracted the attention of many consumers, and gave a fairly high expectation.
this way of starting from the power supply is to directly use half-bridge or full-bridge high-efficiency switching power supply on the existing led display screen, coupled with significant energy-saving effect of synchronous rectification; secondly, to minimize the power supply voltage under the condition of driving ic constant current, and to achieve better energy-saving effect through separate power supply of red, green and blue cores. 。 of course, the application cost of this kind of non-standard voltage power supply and new technology will inevitably rise. from the point of view of screen drive ic, energy saving is not obvious. reducing the constant current differential pressure will bring new problems including cost. some ic companies publicize energy-saving design driven by sales strategy.
technology upgrade is the key to energy saving of led display screen
so, in addition to energy-saving from the power supply of led display screen, what other ways can better achieve energy-saving of led display screen?
compared with other ordinary led display screens, the led display has its own “halo” of energy saving and environmental protection, which has the function of brightness self-regulation. therefore, another aspect is to achieve the purpose of energy saving by adjusting the brightness of the led display screen.
the light-emitting materials used by the led display screen itself are energy-saving products. however, due to the large area and high brightness of outdoor display, there is still a certain demand for power consumption. however, the brightness of outdoor led display screen needs to be reduced in the evening due to the great changes of ambient brightness during the day and night. therefore, the self-adjusting function of brightness of led display screen is very necessary, and the self-adjusting function of brightness of led display screen is to adjust automatically according to the brightness of external light. no parameter setting is required. it is more convenient and convenient.
