Display spectral and angular test fixture
Independent traceable visible spectral radiance/luminance/color, full-area pixel uniformity and viewing-angle measurement with dark/stray/polarization handling; range includes2600cd/m2 and black-to-white behavior, exact uncertainty and spatial aperture matched to61.105um pixels andΔEcriterion.

Capability requirements and tolerances
Consumer-specific numerical targets, quantities and acceptance limits remain open or incompletely reviewed. No smartphone-grade suitability is claimed. Distinct capability tiers require their own making route and qualification.
Parts and Tools needed
No researched inventory yet. This is an unexpanded frontier; an empty list does not mean the item can be obtained directly from nature.
What remains unresolved
- Specific child making route, exact grade and earlier independent reference are not approved.
