E-newspapers just around the corner. Really.

NEW YORK, June 13 (Reuters) The newspapers of the future - cheap digital screens that can be rolled up and stuffed into a back pocket - have been just around the corner for the last three decades.

But as early as this year, the future may finally arrive. Some of the world's top newspapers publishers are planning to introduce a form of electronic newspaper that will allow users to download entire editions from the Web on to reflective digital screens said to be easier on the eyes than light-emitting laptop or cellphone displays.

Flexible versions of these readers nay be available as early as 2007.

The handheld readers couldn't come a moment too soon for the newspaper industry, which has struggled to maintain its readership and advertising from online rivals.

Publishers Hearst Corp. in the US, Pearson Plc's Les Echos in Paris and Belgian financial paper De Tijd are planning a large-scale trials of the readers this year.

Earlier attempts by book publishers to sell digital readers failed due to high prices and a lack of downloadable books.

But a new generation of readers from Sony Corp. and iRex, a Philips Electronics spin-off, have impressed publishers with their sharp resolution and energy efficiency, galvanising support for the idea again.

''This could be a real substitution for printed paper,'' Jochen Dieckow, head of the news media and research division of Ifra, a global newspaper association based in Germany, said.

It's easy to see why publishers are keen. Digital newspapers, so called e-newspapers, take advantage of two prevailing media trends -- the growth of online advertising and widespread use of portable devices like the iPod music player.

Nearly all papers run Web sites, but few readers relish pulling out laptops in transit or risk dropping one in the bathroom.

E-newspapers would cut production and delivery costs that account for some 75 per cent of newspaper expenses.

Circulation in the 55 billion dollar US newspaper industry has slid steadily for nearly two decades as papers compete with Internet news for attention and advertising dollars.
