LG may be bringing the curved display from the G Flex line to their next flagship smartphone, which is rumored to be launching towards the end of April. Their next flagship, which is probably the LG G4, is said to feature a Quad-HD display somewhere around 5-inches in size that is also curved, according to The Korea Herald:

South Korea's No. 2 handset maker, LG Electronics Inc., is set to roll out its next flagship smartphone at end-April, seeking to take on its bigger rival Samsung Electronics Co., which will also release new Galaxy smartphones in two weeks, industry sources said Friday.

With the G Flex series, LG offers a curved and flexible display, but this display may just feature the curve without the flex.

It was reported in February that the next LG flagship device would not arrive until April at the soonest. We have seen the latest offerings from HTC with the One M9, and Samsung with the Galaxy S6 and Galaxy S6 edge. With the LG G3 having been on the market for just under one year, it seems likely that a successor could soon be announced.
