The electronic newspaper, a large portable screen that is constantly updated with the latest news, has been a prop in science fiction for ages. It also figures in the dreams of newspaper publishers struggling with rising production and delivery costs, lower circulation and decreased ad revenue from their paper product.

While the dream device remains on the drawing board, Plastic Logic is introducing its version of an electronic newspaper reader -- a lightweight plastic screen that mimics the look, but not the feel, of a printed newspaper.

The device, which is unnamed, uses the same technology as the Sony eReader and Amazon's Kindle (photo above).

Both of those devices are intended primarily as book readers, but Plastic Logic's device has a screen that is more than twice as large. The size of a piece of copier paper, it can be continually updated via a wireless link and can store and display hundreds of pages of newspapers, books and documents.

The reader will go on sale in the first half of next year. Plastic Logic will not announce which news organization will display its articles on it until the International Consumer Electronics Show in January, when it will also reveal the price.
