With the continuous development of the LED electronic screen industry and the continuous updating of products, the further energy-saving of LED electronic screens has become the support point of the pursuit of this industry. Many companies have made various improvements on this point, improved to a certain extent, and achieved energy-saving effects. However, there is still a long way to go to achieve greater energy-saving, which requires the joint efforts of the entire industry. Hard work.

Now 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 electronic screens, which has attracted the attention of many consumers and has given quite high expectations. , Many LED display manufacturers are eager to try and are ready to introduce this technology first to gain development opportunities. Based on the current technology, how is the energy-saving effect of energy-saving LED display realized?

We use a small led module to analyze its power consumption! It is a small led module that drives the chip. Its power supply voltage is 5V. The power consumption of peripheral devices is not calculated first, because they occupy a very small proportion in the entire screen. , The power consumed by the entire screen is on the lamp, first calculate the lamp point power as Pled=n*Uvf*Iled (n is the number of channels, Uvf is the voltage drop of the LED lamp point, and Iled is the set current value) CYT62726 The pin voltage drop of the driver IC is generally about 0.6V, and the voltage drop of the red, green and blue light points are 1.8V, 3.0V, 3.0V, so that each channel only needs 4V (3.0+0.6V) to work normally. To be conservative, it can be set to 2.8V for the red light channel and 3.8V for the blue and green channels. In fact, our power supply voltage is 5V, which is equivalent to increasing the power consumption of 1V*Iled inside the IC, so it can be imagined as long as the power supply Reducing to 2.8V for red, 3.8V for green, and 3.8V for blue, we can save the 1V*Iled power consumption added to the IC channel, and the LED display can save energy by at least 15% while other devices remain unchanged. , Coupled with the reduction of the heat dissipation requirements of the LED screen itself can also achieve a certain degree of energy saving, which is already a considerable number for a large screen, and I believe customers will be happy to accept it.
