The precision color calibration software, Ultimate PWM Program (UPP) developed by Brightek, is designed to process RGB color calibration fast and accurate, up to 5X faster than traditional methods, with an impressive accuracy.

UPP Advantages

• Faster Calibration - Advanced algorithms streamline color tuning, significantly reducing development time.  

• 99% Accuracy - Converts CIE chromaticity coordinates into pre cise PWM signals for exact color matching.  

• Tuning Under All Conditions - Compensates for brightness non-linearity and temperature-induced color shifts. Uniform Appearance - Ensures consistent color across multiple LEDs, even with surface variations

The Ultimate PWM Program (UPP) is engineered to solve the most critical pain points in automotive RGB LED calibration including non-linear brightness adjustments, temperature-induced color shift and module surface effects. The UPP can transform a complex task into a streamlined, high-precision process.

How It Works: A 6-Step Precision Workflow

(1) Device Selection: Getting started is effortless. Simply connect your hardware and select the specific color meter and Brightek LED control board. Selected color meters and LED boards should be configured using integrated dropdown menus.

(2) Primary Color Measurement: Capture the unique baseline of your LEDs using the "Measure" function. The "Update Learning" feature then synchronizes this data with UPP’s core algorithm to account for manufacturing variations.

(3) Input Target Coordinates: UPP offers flexible input methods to fit any design requirement. You can manually enter target Lv, x, and y values, batch-load coordinates via CSV files, or select colors visually from the CIE 1931 color picker or plot.

(4) Automatic Calibration: Once targets are set, UPP’s advanced algorithms automatically convert CIE chromaticity coordinates into precise PWM signals.

(5) Verification & Monitoring: Ensure perfection with real-time feedback. Use "Show Regression Progress" to monitor the convergence toward target colors and the "Verify PWM" tool to confirm the final calibrated output.

(6) Export Results: Transition seamlessly to the production line. Finalized PWM values can be exported as a CSV file, providing ready-to-use data for mass manufacturing.

System Requirements

1. Connected Color Meter 

2. Connected LED Board 

3. CSV file (optional, for batch calibration) 

4. Supported Windows operating system

It is required to use Brightek’s LED board to process the RGB LED calibration.

Optimal Calibration Environments: Dark Room vs. Open Area

Prepare a proper working environment depending on your color meter’s sensitivity. 

There should be no gap between the light board and the color meters. 

If a gap is unavoidable, calibration must be performed in a dark room to ensure optimal accuracy.
