ROI Calculation Logic

Assuming product power consumption could be reduced by ~20% due to lower drive voltage and higher luminous efficiency. For an annual production of 1 million displays, with an average annual power consumption cost of ~$7.50/unit (AI est.), the total annual power consumption cost would be ~$7.5M (AI est.). This ~20% reduction could result in an annual operational cost saving of ~$1.5M (AI est.).

Speed to Market
4× faster than in-house development
This technology has an established basic material design and device structure, already patented. Developing an equivalent technology from scratch would require at least 4 years for material selection, device structure design, and film deposition process optimization. Licensing this technology could significantly shorten the foundational R&D phase, allowing focus on integration into existing manufacturing lines and product tuning, potentially reducing time-to-market to approximately 1 year.
