The Samsung Galaxy S4 release date may have been delayed due to production issues surrounding the smartphone's new display, new reports have suggested this week.

The follow up to the hugely popular Samsung Galaxy S3 handset is being eagerly anticipated by Android users, and rumors already are suggesting the device will feature a 5-inch 1080p Super AMOLED HD panel with 441ppi pixel density.

However, a source in South Korea – home of Samsung – has suggested that the company is struggling to mass produce the new screens as the displays require a hi-tech evaporation technique. According to the reports Samsung is trying to obtain advanced LITI technology from 3M that allows OLED material to be more smoothly printed on glass.

Samsung has been rumored to introduce the new displays to the world at this year's Consumer Electronics Show.

That will surely continue to build excitement towards the release of the Galaxy S4, which has already been rumored to have specs of a quad-core 2.0GHz Exynos 5450 chipset. The new chipset will be faster than the one currently in the Nexus 10 and will be made on a 28nm process.

It is also believed that the Samsung Galaxy S4 will feature a 13-megapixel camera. This 13-megapixel sensor was originally planned for the Galaxy S3 and second-generation Galaxy Note, but due to the time schedule to get the S3 out it was decided to hold the new top level cameras back and put them into the next generation Galaxy device. A 13-megapixel shooter would be capable of capturing images with 4208 x 3120 resolution.
