Samsung fans waiting for the Galaxy Note 3 release date could be disappointed yet again as new reports point to production delay on the Youm flexible display technology, touted as one of the cutting-edge features of the upcoming phablet.

Korean news site ETNews reported this week that Samsung engineers encountered fresh issues in the mass production of the bendable display screen that was showcased earlier this year via the 2013 CES in Las Vegas.

Samsung Display, the report said, "is having difficulty upgrading its encapsulation technology ... was turning its eyes to other technologies since the ... encapsulation technology excessively lengthens the manufacturing time."

Perfecting the encapsulation process is crucial to the mass production or commercialisation of flexible displays "since OLEDs are vulnerable to moisture and oxygen."

To stabilise the equation, the procedure should be completed below the minute mark, which is an adjustment that currently is being put in place by Samsung.

"We have developed a new technology than can shorten the encapsulation process to less than 2 minutes," the ETNews report quoted Samsung Display as saying.

That would mean the slight has been resolved and manufacturing of the device that will first show off the durable display screen is back online.

According to earlier reports, that device would be the Note 3, which is slated for a September 2013 release date.

It was not clear, however, it a release pushback is necessary to accommodate the production revisions for Samsung's third-gen phablet.

Rumoured specs of the oversized smartphone include the across the board deployment of the 8-core Exynos Octa 5 and Google's Key Lime Pie or Android 5.0.

Samsung watchers also anticipate the device to sport a 6-inch screen but with a leaner, lighter and thinner profile, achieved by adopting a bezel-less screen design.
