The energy savings achieved by reducing the power supply voltage are limited to a single technical approach. The outdoor LED large-screen energy-saving solution utilizes a DSPWM constant current driver IC combined with a 4V power supply, taking a two-pronged approach that significantly enhances energy efficiency and delivers real, measurable energy savings.
**Energy-Saving One: Starting from the Core**
The DSPWM constant current driver IC used in the outdoor LED large-screen energy-saving solution is based on a dual-latch constant current driver IC. It maintains high-brightness display performance while adding an intelligent brightness-adjusting energy-saving driver IC. Its low-voltage turn-on technology can reduce the power consumption of the driver IC by 20–25%. When tested on a 1 m² P5 outdoor surface mount module, the DSPWM constant current driver IC showed 21% lower power consumption than standard constant current ICs, equivalent to saving 1,000 units of energy per year. When applied to hundreds of outdoor LED large screens, a 100 m² screen can save up to 100,000 yuan in electricity costs annually.
**Energy-Saving Two: Starting from the Outside**
Using a 4V power supply along with an LED large screen equipped with a DSPWM constant current driver IC proves to be a more suitable and efficient option. It fully supports normal operation of the LED screen, allowing each power device to function properly even at reduced voltage. This eliminates heat loss caused by excess voltage and ensures that the brightness of the LEDs remains unaffected. As a result, the lifespan of the LEDs is also effectively extended. This dual approach enables more efficient energy savings.
**Energy-Saving Solutions Go Beyond Just Saving Energy**
The outdoor LED large-screen energy-saving solution not only reduces energy consumption and emissions but also offers several times better display performance compared to traditional constant current ICs.
**Enhancement One: Increase Refresh Rate and Brightness**
The outdoor LED large-screen energy-saving solution with DSPWM constant current driver IC uses a double-latch DS-PWM protocol. Compared to conventional constant current chips under similar conditions, it increases the refresh rate by 2–4 times, reaching over 1920Hz, and boosts brightness by more than 15%.
**Enhancement Two: Built-in Shadow Elimination Function**
The DSPWM constant current driver IC features an integrated shadow elimination function, paired with a line driver chip that completely removes the "row and shadow" effect on the LED screen, resulting in a smoother and more refined display.
**Enhancement Three: Intelligent Brightness Adjustment**
With an internal current adjustment function and control software, the DSPWM constant current driver IC allows for 32 levels of intelligent brightness adjustment. It adapts to different lighting environments, adjusting current levels accordingly to achieve energy savings and emission reduction.
**Enhancement Four: Built-in Low Gray Improvement Function**
The DSPWM constant current driver IC supports a working voltage of 3.3–5V and includes built-in low gray improvement and current accuracy enhancement functions. It addresses common issues such as red color imbalance on both sides of the module, low gray color block problems, and screen cascading issues, ensuring a more accurate and perfect display.
