LG.Philips LCD on Sunday took the wraps off the world's first A4-sized color "e-paper" display, following up on its black and white display of the same size a year ago.

The 14.1-inch, 4,096-color display is paper-thin and flexible, and can be viewed from up to a 180-degree angle, meaning images remain crisp even when the display is twisted around, the company said.

The image is designed to be comparable to print quality, LG.Philips said. The display is less than 300 micrometers thick, and only uses power when the image changes.

E-paper is a concept designed to open up new frontiers in the world of LCD displays and to replace paper in some cases. A number of companies have debuted prototypes of such lightweight, thin, flexible displays, including Taiwan's Prime View International (PVI) and Japan's Seiko Epson.

LG.Philips' version of the technology uses a substrate that arranges Thin-Film Transistors (TFT) on metal foil rather than glass, making the display flexible and allowing it to return to its original shape after being bent. The latest display includes a color filter coated onto the plastic substrate.

The company's development process for the color display centered on overcoming processing difficulties related to the lack of heat resistance in metal foil and plastic substrates.

That meant developing processing technology that minimizes panel deformation and prevents circuit structure change during high-temperature processes, as well as research into the lamination technology and the design of the transistors and color filter, the company said.

PVI recently introduced Vizplex, an e-paper technology that, like LG.Philips' displays, uses electronic ink from E-Ink. PVI's smaller displays, between 1.9 inches and 9.7 inches, are due out this summer and are designed for mobile phones, music players, bulletin boards and electronic books.

Seiko Epson introduced a high-resolution, A6-sized e-paper display using E-Ink and a manufacturing technique called surface-free technology by laser annealing (SUFTLA).

It has long been predicted that books are about to be replaced. Andrew Marr spent a month using one of the most recent gadgets

If you are selling ebooks, I'm a hard sell. For one thing, my enthusiasm for traditional books is just this side of pervy. I live among mountains of them and always have, among the most beautiful mass-produced objects of all time. Some of my most treasured possessions are broken-backed, scribbled-in, jacketless books first read when a teenager; they've lasted longer than merely human friends. When I eventually become a nasty-minded, dribbling old man I'm sure I will be found creeping round second-hand bookshops, sniffing the produce, snuffling with pleasure.

If, that is, the bookshops are still there, and have not been put out of business by ebooks -- digital versions that can be read on computers or hand-held devices. But I'm a sceptic. A very long time ago, 10 years or more, I vividly remember being at Davos for the rich-or-clever people's annual frolic in the snow, and being assured that epaper -- "electronic paper" -- was about to transform the way we read.

So why the tortoise progress of the ebook?

It's partly that traditional books are such good technology. They are a little larger than the hand, extremely portable, nice to hold and look at and remarkably cheap. Yes, there is an environmental issue but most are made of cheap, sustainable woodpulp. Simple technology that works is unlikely to go out of fashion.

Beyond that, most ebook readers simply aren't good enough, whether they're dedicated devices or the multi-purpose palmtop computers made by the likes of Palm and Hewlett-Packard. They're fine to use for an hour or two when you are sitting upright in even indoor light, but they're pretty useless when you are traveling, sitting in the garden or slumped in the bath. The ebook reader that is as easy on the eye as a real book, and as quick to flick through, and as portable, hasn't arrived.

Or perhaps it has. Enter Sony's Reader and iRex's Iliad, which are being touted as the first really useable, easy-to-read products. I've had an Iliad for a month to try out. It costs ?449 (US$890) plus VAT, or slightly more with a handsome leather case that makes it look like a slightly larger, thinner Filofax.

It is meant to be read, at length, and its claim is that the screen is good enough to allow you to read, even a Tolstoy, even in sunlight, and actually enjoy the experience. It works with a basic menu, four buttons separated into news (of which more anon), books, docs and notes. There is a small pen-like stylus attached to the back, which lets you make notes or add comments to your documents and -- the best innovation -- a thin silver bar on the left of the screen that you flick with your thumb to turn the pages.

It is charged, like a laptop, mobile or any other similar device, and the battery should see easily you through a day's reading and writing. For those interested in detailed specifications, I can say it weighs about the same as a medium-sized banana. It powers up quickly and turns off easily.

Here is the first crucial thing: the screen does work. By "work", I mean that the words stand out clearly without shimmering, and that you can certainly read it outside, in dappled light and direct sunlight, as you would not be able to read a normal computer screen. The effect is matt, not shiny, and black-and-white, not color.

What about page-turning? It is slower than a book. There is a distinct "one-and-two" count as the page dissolves and re-forms after your thumb has touched the flicker, and it can be disconcerting. I found it more cumbersome than turning a page. Speeding this up will be important if the ebook is to really catch on. There is a scroll-bar on the bottom of the page, and with the stylus you can jump to different parts of the book, but again this is slower than the real thing, and obviously you can't turn over the corners of pages -- electronic bookmarks are, we're promised, on the way.

My advice to the makers is to refine the page-turning just a little more, offer a battered blue cloth-bound wallet and, above all, make it smell -- just a little musty, please. Or dank. You could offer a choice. But it's clear enough that after all the waiting and the over-hyping, the ebook is arriving. Before long you are going to see them being carried nonchalantly around. And after that some of you, at least, are going to buy one.
