ROI Calculation Logic

This technology simplifies wiring routing and connection processes in the display periphery, leading to significant manufacturing cost reductions. For example, the implementation cost for peripheral circuits, which was approximately $1.65 per display unit with conventional technology, could be reduced by ~$0.65 to ~$1.00 per unit (AI est.) with this technology. For a company producing 1 million display units annually, this unit cost reduction translates to over $650K per year ($0.65/unit × 1,000,000 units) (AI est.). This is expected to optimize manufacturing costs and improve profitability.
