Just when you thought smartphone displays couldn’t get bigger, Samsung may be ready to push the outside of the envelope even further.

Samsung Electronics may be looking to blur the lines between a phone and tablet even further.

The Korean electronics giant is working on a bigger, 6.3-inch display for the eventual Galaxy Note 3, according to the Korea Times.

Samsung has pioneered the category that some refer to as the “phablet” segment, or something between a smartphone and tablet. Initially mocked for the size of the device, Samsung saw decent sales of the first big-bodied Galaxy Note, and pushed for wider distribution with the successor Galaxy Note 2, which saw its display grow to 5.5 inches from 5.3.

Samsung has continually hammered the point that the Galaxy Note has been successful around the world, and has been unusually quick to tout sales numbers as it justifies the new category. Last month, it said it sold 5 million units of the Galaxy Note 2 in two months, or double the rate of the original.
