In the past, Powerful Color has been dedicated to advancing the LED industry, delivering top-tier products and services to its customers. From promoting surface-mounted stickers to popularizing high-definition, high-order PWM driver ICs, and even standardizing cell board sizes at 320*160mm, the company has consistently pushed for innovation. This time, Powerful Color is once again revolutionizing the outdoor LED large-screen market with a new energy-saving solution that promises real efficiency and performance improvements.
**Two-pronged Approach for Greater Energy Efficiency**
Traditional methods of energy saving by lowering voltage have their limitations. However, Powerful Color’s latest outdoor LED large-screen energy-saving solution takes a dual approach—combining DSPWM constant current drive ICs with a 4V power supply. This combination significantly enhances energy efficiency, delivering a more substantial and sustainable energy-saving effect.
**Energy-Saving One-Piece: Starting from the Core**
The DSPWM constant current driver IC used in this solution is based on a double-latch design, ensuring high brightness and display quality while adding intelligent brightness adjustment. The low-voltage turn-on technology reduces driver IC power consumption by 20–25%. For example, a 1m² P5 outdoor module using the DSPWM IC consumes 21% less power than a conventional constant current IC. This translates to significant annual savings—equivalent to 1,000 kWh per unit. When applied to hundreds of outdoor LED screens, a 100m² screen can save up to 100,000 yuan in electricity costs annually.
**Energy-Saving Duo: Starting from the Outside**
With a 4V power supply and DSPWM constant current drive ICs, the system operates more efficiently. Each power component functions normally under reduced voltage, eliminating heat loss and preserving the lamp’s brightness and lifespan. This dual strategy ensures greater energy efficiency without compromising performance.
**Energy-Saving Solutions Go Beyond Just Saving Power**
Powerful Color’s outdoor LED energy-saving solution not only cuts energy use and emissions but also delivers performance that far exceeds traditional constant current ICs.
**Enhance 1: Higher Refresh Rate and Brightness**
Equipped with the DSPWM constant current drive IC, the system uses a double-latch DS-PWM protocol. Compared to standard ICs, this increases the refresh rate by 2–4 times, reaching 1920Hz or higher, and boosts brightness by over 15%.
**Enhance 2: Built-in Shadow Elimination Function**
The DSPWM IC features an integrated shadow elimination function, paired with a line driver chip that effectively removes "row and column shadows" from the LED screen, resulting in a much smoother and more detailed display.
**Enhance 3: Intelligent Brightness Adjustment**
With built-in current adjustment capabilities and control software, the DSPWM IC supports 32 levels of intelligent brightness adjustment. It automatically adapts to different lighting environments, optimizing energy use and reducing emissions accordingly.
**Enhance 4: Low Gray Level Improvement**
The DSPWM IC supports a 3.3–5V working voltage and includes low gray level improvement and current accuracy enhancement features. It solves common issues like red color imbalance, low gray color blocks, and screen cascading problems, delivering a more accurate and visually pleasing display.
To achieve both energy savings and superior visual performance, Powerful Color’s outdoor LED large-screen energy-saving solution—featuring DSPWM constant current drive ICs and a 4V power supply—is now being rolled out across all outdoor LED surface-mount products. Whether you're looking for a high-quality LED screen or an energy-efficient outdoor display, look no further than Powerful Color. Do LED big screens—choose Powerful Color; do energy-efficient outdoor LED screens—still choose Powerful Color!
