Shortage of OLED Panels Forcing Chinese Vendors to Try Mini LEDs
January 22, 2018

Chinese smartphone vendors are considering switching to MiniLED displays as early as the second half of 2018, if AMOLEDs continue to be in short supply. DigiTimes indicated that China-based smartphone vendors, including Huawei Technologies, Xiaomi Technology, and Oppo could adopt mini LED-backlit panels
For this new technology, these Chinese smartphone vendors have requested that Taiwan-based LED makers start producing mini LED backlighting in June 2018, according to the article that cited industry sources. Industry insiders said that through design and technology improvement, the number of mini LED chips used for 6-inch smartphone panels can reportedly decrease from 9,000 to 4,000, which will greatly reduce production cost. Notably, a TV needs about 10,000 mini LED chips for backlighting. Epistar says that production of mini LED backlighting for smartphones and TVs is likely to begin in second-half 2018, with specifications to be created in the first half. Existing LED production equipment can reportedly be adjusted to produce mini LED chips.
