Tablet shipment is expected to grow 23.9% this year.
Gartner predicts that the tablet market is expected to witness a relative slowdown in demand during 2014.
Tablet shipment is expected to grow 23.9% this year to 256 million units, compared to 206 million units shipped in 2013 and reach to 316 million units by 2015.
Cooling in demand could be due to users favouring larger screen devices in mature market over the smaller ones and shift in demand for phablets in South-East Asia.
Gartner research director Ranjit Atwal said, "The next wave of adoption will be driven by lower price points rather than superior functionality."
Atwal added that for any device, the adoption goes through phases from the early to the late adopter, tablets are currently moving on the latter part of that curve in mature markets.
Mobile phone sales are expected to grow 3.1% this year to 1.9 billion units while sales of smartphones, which exceeded those of the rest of the market in 2013, will continue to do well, the analysts added.
Smartphone will account for 88% of the total mobile phone sales, rising from 66% in 2014.
Android and iOS operating systems will continue to drive smartphone growth recording a respective growth of 30% and 15%.
Gartner research director Annette Zimmermann said, "We expect the announcement of the new Apple iPhone 6 will attract pent-up demand for users who want a larger screen."
"Windows phones will exhibit strong growth from a low base in 2014, and are projected to reach a 10 percent market share by 2018 -- up from 4 percent in 2014," Zimmermann said.
