QMC's proprietary production technology is what UDC does not has. QMC's products have universal applications and can be customized to the customer specifications.
UDC's proprietary OLED Display technology is confined only to the field of Display and with its unique characteristics: Burn in defect, low luminance and limited color gamut (banana looks brownish yellow, red delicious apple looks piky red etc.), pixel degradation in high humidity environment, complicated and expensive manufacturing, high TV sale prices and short lifespan. Good luck to your investment in OLED stock which hedge fund managers have been dumping.
