Backlight Module Viewing Angle Calculation via Color Saturation

The patent introduces color saturation data as an intermediary parameter to bridge the gap between available measurement data and the desired brightness-viewing angle parameter. By establishing a correlation model between color saturation-viewing angle and brightness-viewing angle, the system can indirectly determine brightness characteristics without direct measurement, thus resolving the contradiction between measurement feasibility and accuracy.

The patent replaces direct brightness measurement (mechanical/optical measurement system) with a calculation-based approach using color saturation data. Instead of physically measuring brightness-viewing angle directly, the system substitutes this with mathematical modeling based on color saturation correlations, achieving the desired parameter through computational means rather than direct physical measurement.

The patent creates a universal calculation model that can be applied across different backlight module types. By establishing a general correlation between color saturation-viewing angle and brightness-viewing angle that transcends specific module characteristics, the system achieves consistent results regardless of which backlight module is used for measurement, thus providing universality and resolving the consistency issue while maintaining flexibility.

The patent transforms the measurement approach from direct physical measurement (which varies with module differences) to parameter-based calculation using color saturation data. By changing from measuring absolute brightness characteristics to calculating relative viewing angle parameters through correlation models, the system eliminates variability introduced by different backlight modules while maintaining measurement flexibility.
