Kent Displays, the company that makes the Boogie Board tablet, is getting more VC money and is hiring 40 more employees in Ohio.

The Boogie Board is a modern equivalent to the old-fashioned chalk slate – a device that allows users to write and quickly erase messages on a screen the size of a sheet of paper. Company spokesman Kevin Oswald said orders for the boards have forced the plant to run three shifts a day for much of the year.

He added that he expects orders to increase this fall when the company adds a version of the board that can save images for later use.

“[The expansion] will allow us to meet worldwide demand for the Boogie Board tablets for the foreseeable future,” Oswald said.

Sales of multimedia tablets, such as Apple’s iPad or Motorola’s Xoom, have boomed this year, but Oswald said Kent’s product doesn’t compete with those. Boogie Boards cost $40-$60, depending on size, and are meant as a replacement for notepads and paper, not computers.

It will be interesting to see if this technology eventually finds it’s way into the all-purpose tablets.
