WUHAN - A Chinese company has started building the country's first production line for flexible display, which would make China a supplier of the product often used to make bracelet-shaped mobile phones and folding tablets.

CSOT, a subsidiary of Chinese smart product maker TCL Corp, on Tuesday started building the 35-billion-yuan ($5 billion) production line in Central China's Wuhan city.

Known as AMOLED (active matrix/organic light-emitting diode) display, it is physically flexible with fast response, high contrast and wide visual angles, compared to traditional LCD panels.

CSOT's production line is expected to start production in the second quarter of 2019, and by 2020, its annual output will reach 1.16 million square meters -- enough to produce 5 percent of the world's AMOLED smart phones.

In addition to manufacturing, the company has invested in developing new applications and products with AMOLED display.
