Samsung Display (Display) and LGD (LG Display) as the leading organic light emitting diode (OLED) in the market, is committed to introducing the inkjet printing process. Two Korean panel factory will more early than market expectations, in 2017 started the demonstration production line, ensure the RGB OLED display capacity.
Near Beijing Oriental (indicate), huaxing photoelectric (CSOT) such as the main display panel industry master LCD market dominance, in order to ensure the OLED market competitiveness, will accelerate the introduction of the inkjet printing process.
The south Korean display panel industry insiders revealed that the industry for 1 year ahead of the introduction of ink-jet printing process, already begin to prepare. The future will be based on this, production of large size RGB OLED display, rather than WRGB OLED panel.
Samsung and lg display monitor, etc. A few years ago from experiments actively for ink jet printing technology research and development of production line. Current equipment research and development progress has reached the level of can be available, but the life of the materials used in inkjet printing equipment of OLED and needs to improve the performance, it is generally believed to formal import, in the process of production will be 2 ~ 3 years.
Ink-jet printing process is to dozens of one over one million liter (Picoliter) the following solution, more than hundreds of times per second the frequency of the spray pattern in the printing process on the object technology, compared with the traditional vacuum evaporation process, material use efficiency, can increase yield significantly.
The inkjet printing process due to the alternative to semiconductor, display etching process.
If use OLED solution, more conducive to ensure the RGB technology of OLED panel capacity.
Samsung and lg display monitor and Kateeva, Tokyo power (Tokyo Electron) and other equipment factory, and Merck (Merck), Idemitsu Kosan (Idemitsu Kosan) materials such as industry cooperation, each in A3 and M2 production line to bring the inkjet printing process.
South Korean industry thinks, intelligent mobile phone sales each year to more than 200 million Apple (Apple), the plan since 2017, adopt flexible OLED, two panel factory should start from small and medium size OLED panel introduced inkjet printing equipment.
Most of South Korea display in the industry, said the industry knows that samsung display has ensured apple flexible OLED panel order. LGD and Japan displays (JDI) in order to ensure the future of apple's supply chain can be added, such as competitive is also committed to strengthening type flexible OLED panel.
For medium and long-term development, on the other hand, ink-jet printing process can be used to ensure that large OLED panel production capacity, in terms of long-term, ink-jet printing process can also be across OLED, applied to quantum dot light emitting diode (QLED) panel production process.
