This system provides comprehensive optical simulation capabilities for direct-lit and edge-lit backlight modules. It supports optical modeling of thousands of independent local dimming zones, accurately simulating light diffusion, mixing distance, and light leakage characteristics. Using fast ray-tracing algorithms, it predicts luminance distribution and blooming effects after zone activation, optimizing backlight structure and driving strategies. The system significantly reduces physical prototyping, shortening the R&D cycle by over 30%, enabling the design of high-contrast, low-power HDR displays for TVs, automotive panels, and professional monitors.
