South Korean panel maker Samsung Display has decided to end all of its production of liquid crystal display (LCD) panels in South Korea and China by the end of this year, a spokeswoman said on Tuesday.

Samsung Display, a unit of South Korean tech giant Samsung Electronics Co Ltd, said in October that it suspended one of its two LCD production lines at home amid falling demand for LCD panels and a supply glut. “We will supply ordered LCDs to our customers by the end of this year without any issues,” the company said in a statement.

In October, the Apple Inc supplier said it will invest 13.1 trillion won ($10.72 billion) in facilities and research to upgrade a production line, as it contends with oversupply amid weak global demand for smartphones and TVs.

The investment for the next five years will be focused on converting one of its South Korean LCD lines into a facility to mass produce more advanced “quantum dot” screens.

“Quantum dot” screens are exactly LCD screens just with one additional layer (or some modern even without it!). All QD is doing is just changing led spectrum, and it is all.
