The concept of energy saving of LED display screen has been quietly launched, which has become the most eye-catching bright spot for consumers, and it is also the reason for the rapid growth in recent years. Of course, after the frenzied growth in recent years, the industry is currently stuck in a kind of stalemate to reshuffle. In this predicament, there are bound to be many companies affected by this and their vitality is severely damaged, or even bankruptcy. Of course, many companies will get out of the haze and achieve longer-term development. This is the law of development of the industry. No enterprise can escape this catastrophe. How to rebirth in the catastrophe is a problem that every enterprise is more concerned about at present.
In this era of high energy conservation, the further energy conservation of LED display screens has become the support point of the pursuit of this industry. Many enterprises have made improvements in various aspects on this point, and to a certain extent, they have achieved the effect of energy saving, but there is still a long way to go to achieve energy saving in a greater sense, which requires the joint efforts of the entire industry.
Recently, there are a few energy-saving LED displays on the market. The improvement of the power supply has greatly improved the energy-saving effect of LED displays, which has attracted the attention of many consumers and given them high expectations. , Many LED display manufacturers are eager to try and prepare to introduce this technology first to gain development opportunities. On the basis of the current technology, how is the energy-saving effect of the energy-saving LED display realized?
The realization of LED energy-saving display mainly starts from the power supply. In the existing LED display, a half-bridge or full-bridge high-efficiency switching power supply is directly used, coupled with synchronous rectification, the energy-saving effect is remarkable. Reduce the power supply voltage as much as possible under the constant current state of the driver IC, and achieve better energy-saving effect by separately supplying power to the red, green and blue die. Of course, the application cost of this non-standard voltage power supply and new technology will inevitably rise. From the perspective of the screen driver IC, the energy saving is not obvious, and reducing the driving constant current voltage difference will also bring new problems including cost. Some IC companies promote energy-saving designs because of sales strategies.
