Light Guide Uniformity Simulator — see your backlight hot spots

Render the per-pixel brightness map of an edge-lit light guide. Add a Kriya low-index cladding and watch the hot spots at the LEDs collapse as more light stays guided.

Backlight uniformity is a single number on a spec sheet but a visible pattern on the panel. This tool shows the pattern. Pick your plate size, LED edges, extraction pattern, and cladding stack; the kernel computes brightness at every pixel from the Fresnel + TIR physics; the scene renders it. Compare an incumbent cladding with a Kriya LRI side-by-side — the hot spots dissolve as alpha drops.
