ROI Calculation Logic

Adopting this technology could improve OLED display manufacturing yield by 5%, reducing defect disposal costs. Additionally, a 10% extension in product lifespan could lower warranty replacement expenses. Assuming an annual production of 1 million units, a defect disposal cost of ~$3.35/unit (AI est.), and a warranty replacement cost of ~$6.65/unit (AI est.), the estimated annual savings are: (1M units × 5% × ~$3.35/unit) + (1M units × 10% × ~$6.65/unit × 0.1) = ~$167.5K + ~$66.5K = ~$234K/year (AI est.).
