Applying dynamic runtime corrections to neutralize chromatic drift induced by operating temperature fluctuations.

Comparison

Firmware vs. Software Profiling

Standard ICC software profiling operates downstream of the graphics pipeline, clipping gamut boundaries and compressing tonal gradations when forcing displays to match target profiles. This introduces contouring artifacts and banding in low-luminance steps.

Our approach bypasses OS-level approximations entirely. By writing correction matrices directly to display controllers at the silicon driver level, we preserve native bit depth while maintaining strict delta-E tolerances across all luminance levels.
