Apple will come out with two new iPhone models this year, and each one will feature a larger screen, sources say.

The Cupertino tech giant will release a version of its flagship device that features a screen larger than 4.5 inches and another with a screen that is larger than 5 inches, according to the Wall Street Journal. Current generation iPhones have 4-inch screens.

Development of the 4.5-inch-plus model is further along and is being prepped for mass production. The larger model, meanwhile, is in preliminary development, the Journal reported, citing unnamed sources.

Both new iPhone models will be made of metal and glass, similar to that found on the current top-of-the-line iPhone 5s, the report said.

Apple is also planning to scrap its plastic iPhone 5c model, the report said. The 5c replaced the iPhone 5 in 2013, but the device has failed to find the success its counterpart, the 5s, has.

In September last year, numerous Australian stores reported they were struggling to sell the 5c, while retailers in the US attempted to entice customers to purchase it by dropping its price and offering gift cards.

Apple increased the size of its smartphone screen in 2012, bumping it up from 3.5 inches to 4 inches. The tech giant may be looking to increase the size further as a way to remain competitive in Asian markets such as China, where Apple has struggled to find success. Devices with larger screens, such as the Samsung Galaxy Note 3 with its 5.7-inch screen, are particularly popular in Asian markets.

Apple has been said to be developing versions of the iPhone that come with curved screens, but this report said that technology will not be included in Apple's 2014 iPhone models.
