The sales of iPhone X turned out to be less than market expectation, so Samsung has lowered the utilization rate of OLED production lines. The tight supply of OLED panels over the past two years has also been eased. According to WitsView, a division of TrendForce, Apple has initiated the trend of OLED panels, and it is estimated that the penetration rate of OLED panel in smartphones will reach 46% by 2021. Mini LED is overwhelmed by OLED’s technology maturity and competitive costs, so it might be hard for Mini LED to grow in the smartphone market in short term.

Here begins a debate: when Mini LED is ready to enter the smartphone display market, it have to face an oversupply of OLED screens. Does Mini LED still have chances to grow in this space? And for how long can it last?

After carrying out its capacity expansion plans, major Chinese display maker BOE is reported to share the information about two of its new OLED production lines to Apple in order to win orders from the latter.

China's first Gen6 flexible AMOLED line - BOE Chengdu Gen6 flexible AMOLED production line, on October 26, has put into mass production ahead of schedule. The production line's mass production and products delivery indicate that Chinese enterprises begin to lead the development of the global AMOLED industry in the new display era.
