Solution process using inkjet OLED (sol OLED) has been developed mainly as a large OLED panel for TV, but recently began to attract attention in the monitor display market.

The evaporation method with FMM that produces OLED for smartphones has a bending phenomenon of FMM. Thus, the substrate is used by dividing into two or four. Since smartphone-sized FMMs are used by attaching 10 to 15 sheets to the mask frame, the profitability is very low due to the small number of cells in the production of 20-inch or larger monitors.

In comparison, sol OLED is a highly productive method because OLED can be manufactured from the original substrate regardless of substrate size and display size.

If the 27-inch and 32-inch OLED panels, which are mainly used as gaming monitors, are produced by the FMM method, four can be produced. But sol OLEDs do not divide the substrate, so the 27-inch can make eight, and the 32-inch can make six.

Therefore, in the future, OLED manufacturing technology is expected to be used in combination of three technologies depending on the application and size. Smartphone OLEDs are expected to be divided into FMM and evaporation methods, large OLED panel manufacturing for TVs with open mask and evaporation technology, and sol OLED technology for monitors larger than 25 inches.

There are three types of premium monitor market, LCD, RGB OLED, and sol OLED, but the premium OLED monitor market will be replaced by sol OLED. If 6G-class inkjet lines are invested in large quantities, sol OLED will become the flagship product in the mid-priced monitor market.

The solution process OLED annual report, published by UBI Research (www.ubiresearch.com), expects to create a market of $ 579 million by 2023. This amount represents 85.3% of the OLED monitor market by 2023.
