Over the course of the last two years, worldwide smartphone display shipments have increased 120 percent, and this is down primarily to sales of larger, higher resolution displays, according to a new report from NPD DisplaySearch.
Two devices in particular are driving growth. These are the iPhone, with its 960/1136 by 640 display, and the Samsung Galaxy S3 and S4 models, which have 1270 by 720 and 1920 by 1080 screen resolutions.
A year ago, the 3.5-inch screen, as found on the iPhone 4S and earlier was the most popular screen size, but now displays larger than 4.1-inch account for almost 50-percent of all smartphone displays.
This year, it is estimated that almost 1.2 billion displays, spanning a range of resolutions, will be shipped worldwide.
"Screen sizes are growing, and resolution is increasing, driving growth in the smartphone display market," said Hiroshi Hayase, Vice President of Small/Medium Displays at NPD DisplaySearch. "We can expect still more expansion of displays over 5-inch in the coming quarters, due to the increasing global penetration of the Galaxy S4."
However, nothing stays still as far as post-PC devices are concerned these days, and manufacturers have already begun manufacturing 5-inch full high definition displays, in an attempt to keep up with growing demand for higher resolution and larger screen sizes.
