Dell has unveiled a prototype of a slate PC, which features a slightly larger screen than its current smartphone, the Mini 3i.
The company is experimenting with several different screen sizes, said Michael Tatelman, vice president of sales and marketing in Dell's global consumer group.
"We have a few of these things in the lab," Tatelman said, declining to say when the device will be released or what the final, commercial product will look like. He declined to discuss technical details of the prototype.
Dell released its first smartphone last year and the company is betting on growing consumer demand for smaller, mobile devices that can connect to the internet.
"There's been a tremendous amount of convergence into smaller and smaller screen sizes," Tatelman said, adding that users expect these types of devices to remain connected to the internet at all times.
But smaller screens have their limitations. The advantage of a 5in screen over smaller smartphone screens is that users can more easily view web pages or watch movies, Tatelman said.
