Large size OLEDs cannot pose threat to LEDs: The main obstacle of small size OLED lies in the demand of high pixels per inch (ppi) while in large size it’s limited by yield rate and price. Though LG Display strived to lower the price of OLED TV and adopted the same strategy in selling its display panels to other manufacturers, prices of OLED TVs that are twice higher than LED ones still saw slow progress. It’s projected that OLED TVs will only account for 0.5% in the TV market and rise to 5% as of 2020.
