LG is to start mass production of curved smartphone displays and launch a smartphone with the new screens next month.
Samsung has already announced that it will introduce a smartphone with a curved display in October.
Curved displays are being touted as the next big thing. They allow bendable or foldable designs that could eventually allow mobile and wearable gadgets to take new forms.
This could help along the smartphone market, where new ideas are desperately needed to keep it ticking along.
According to Reuters, LG has started production of a six-inch display curved top to bottom. It plans to launch a smartphone with the curved display in November. Samsung's phone will have a display curved side to side.
Technology firms have yet to figure out how to mass produce the parts cheaply and come up with display panels that can be thin and heat resistant.
LG said its OLED is built using plastic substrates instead of glass, and by using film type encapsulation and attaching protective film to the back, it is "bendable" and "unbreakable".
The company says its screen is vertically concave from top to bottom with a 700mm radius and is 0.4mm thin. LG boasts it's the world's thinnest and lightest, weighing in at 7.2 grams with a six inch screen.
Rumours of curved screens have been floating around for some time now. It was thought while companies were keen to implement them in smartphones, it was first necessary to figure out cheaper production methods that kept phones using the panels cost effective.
