​​Where exactly is the brightness control system of the LED display hidden? ​ ​
Behind the seemingly simple brightness adjustment is the precise collaboration of three major systems: hardware control, software algorithms, and environment perception. As innovative practitioners in the field of LED display, we have independently developed intelligent dimming technology to enable each screen to show the best visual effect in different scenarios.

Hardware control: multi-dimensional regulation from chip to power supply

​​1. Accurate management of driver chips​​
The third generation PWM dimming chip is adopted to achieve a 8192-level grayscale transition through 0.01ms level pulse width regulation. This technology breaks through the traditional 256-level grayscale limit and can still maintain a brightness deviation accuracy of 0.5% at 4000cd/m² brightness.

​​2. Dynamic adjustment of intelligent power supply​​
Configure a dual-loop power supply system to automatically switch the working mode according to the ambient illumination:

• Normal scale: Current is stable at 18mA±0.5mA
• Power saving mode: Current drops to 12mA and maintains 90% brightness
• Enhanced mode: Instantaneous current up to 25mA (duration time <30 seconds)

Software control: Full life cycle brightness management

​​Visual operation platform​ ​Implement three-level brightness control:

1. Global brightness: Unified adjustment of the entire screen (supports 0-100% stepless adjustment)
2. Area brightness: divided into 256 independent control units
3. Pixel-level brightness: Single-point correction technology compensates for brightness deviations within 5%

​​Brightness memory function​ ​20 sets of preset solutions can be stored, and the optimal parameters can be automatically matched through the scene recognition algorithm. Test data shows that this technology reduces screen energy consumption by 38% and increases color reproduction by 12%.

Intelligent perception: environmental adaptive system

Equipped with multi-spectral environmental sensors, collecting 3 types of key data in real time:

• Ambient illuminance (0-100000Lux detection range)
• Color temperature (2700K-6500K dynamic compensation)
• Human eye distance (intelligent recognition 1-50 meters)

In a stadium project in Tokyo, the system implements:

• Daytime 7500cd/m² event mode
• Automatically switch to 1800cd/m² movie viewing mode at night
• Brightness compensation is completed in 0.3 seconds when sudden strong light interference is disturbed

​​Does LED brightness control affect the display effect? ​ ​
We solve industry problems through "low brightness and high gray" patented technology:

• 16bit gray level is maintained at 800cd/m² brightness
• Refresh rate ≥1920Hz to eliminate flash
• Color gamut coverage increased to NTSC 110%

This technology has been applied to transparent screen products with 86% transmittance, while maintaining high light transmission characteristics, it achieves a perfect balance between picture brightness and building lighting.

From hardware circuit design to intelligent algorithm development, the brightness control of modern LED displays has long broken through a single adjustment mode. Through the triple collaboration of environment perception, content recognition, and energy consumption management, each screen can show its best state in different application scenarios - this is the ultimate pursuit of the evolution of display technology.
