SEMES announced on the 4th that it has completed mass production development and made the first shipment of "Vincent," the world's first 8th-generation (2500×2200) high-resolution quantum dot (QD) organic light-emitting diode (OLED) inkjet equipment.
QD inkjet equipment is used in the quantum dot color filter (QDCF) process for manufacturing displays such as high-resolution TVs and monitors. The equipment rapidly dispenses QD ink—quantum dot particles mixed with special solvents—in massive quantities as microscopic droplets at the picoliter (pL, one-trillionth of a liter) level, applying them with precision within micrometers (μm, one-millionth of a meter).
SEMES explained that this technology precisely jets ultra-fine ink droplets half the thickness of a human hair onto the hundreds of millions of pixels that comprise high-resolution display panels. Vincent is equipped with more than 100 ink-dispensing heads to ensure high productivity while improving resolution to 220 ppi (pixels per inch), an increase of more than 30% compared to previous models.
"By securing the world's first 8th-generation high-resolution QD inkjet mass production technology and now successfully shipping our first equipment, we have established technology leadership in the global equipment market," said Han Seok-gu, Display Team Leader. "We expect increased revenue from our technological capabilities as demand grows for high-resolution TVs and monitors."
