One in four Korean consumers is expected to be using a tablet PC this year, according to market research firm Strategy Analytics.
It put the precise share at 26.2 percent of people in the country when it announced the results of its analysis on Sunday. This is lower than 43.8 percent in the U.S., 41.8 percent in the U.K. and 29.8 percent in Taiwan. Hong Kong had the highest rate of 70 percent.
The figure is considered low given that Korea tops the world ranking in usage rate of smartphones with over 70 percent.
The industry believes the relatively low popularity of tablet PCs is due to the high penetration rate of large smartphones with displays measuring five inches or more.
One of the most popular smartphones in Korea, Samsung's Galaxy S5, sports a 5.1-inch display, while the Galaxy Note 3 and LG's G Pro 2 have even larger screens nearing six inches.
As the displays of tablet PCs start from 7 inches there is little incentive for the public to switch over to them from smartphones.
