What is the dynamic energy-saving technology of indoor LED display? The so-called dynamic energy-saving technology means that the chip actively recommends when the flashing information is read, and does not recommend it when there is no information flashing demand. When the dynamic energy-saving function is reached, the power consumption can be reduced. This technology can save energy by 10%-30% (depending on the picture quality). This is for example the active start-stop technology of a car. When the car is in an intermittent state when the clutch pedal is stepped on, the suggestion machine will actively intermittent operation. When the clutch pedal is released, the suggestion machine will actively suggest again, and then save unnecessary fuel consumption.
When the LED display flashes black (uninterrupted power), the PWM-SS dual energy-saving driver IC will enter the sleep state during intermittent operation. For example, if you play a slide show that only needs text, the text is white, and the other areas are black. At this moment, only the text flashing area consumes power. When the entire large screen is in standby mode (uninterrupted power), the entire screen consumes almost no power.
The PWM-SS dual energy-saving driver IC will actively adjust the current according to the changes in the brightness of the flashing screen. The lower the brightness of the playback screen, the lower the power consumption.
The PWM-SS dual energy-saving driver IC can actively adjust the current according to the richness and saturation of the flashing screen color, such as switching from a brightly colored screen to a dimly colored screen, and the power consumption of the display will be reduced. Take the initiative to drop.
In addition to dynamic energy saving, using PWM-SS dual energy-saving driver IC, the power supply provided by the user only needs 4V, and low-voltage energy saving is about 27%. At the same time, the PWM-SS dual energy-saving driver IC has the energy-saving function of DS-PWM and the 4K and 3840Hz refresh rate of the high-definition high-end PWM driver IC. The grayscale processing is more robust. Not only that, the surface temperature of the working display is reduced by 30%. , And the brightness does not decrease.
