UBI Research attributes the OLED substrate area growth to investments made by OLED lines for TVs driven by Samsung Display and LG Display. Currently, OLED manufacturing lines for TVs are 8G lines optimized for 55-inch panel production. However, the demand for premium TVs is shifting from 55-inch OLED TVs to 65-inch TVs. By 2021, the 65-inch OLED TV market will account for more than 40%.
In response to these market conditions, LG Display is preparing to invest 10.5G lines in the most efficient production of 65-inch panels. In 2023, the substrate area of a large OLED line is expected to occupy 42% of the total substrate area.
The substrate area of the 6G line is expected to grow to 13 million square meters this year and to 19.3 million square meters in 2023. Most of this is due to investment by Chinese panel makers. In China, the smartphone market accounts for about 40% of the global market, so Chinese smartphone makers have a very high market share based on the domestic market. Huawei has recently become the world’s second-largest shipper based on its domestic market. Chinese panel makers are boldly adding a 6G flexible OLED line to Chinese smartphone makers, with the Chinese government’s huge support.
