LG.Philips released 14-inch color electronic paper

LG.Philips LCD joint venture intends to impress visitors CES 2008 with a special product: 14.3-inch color electronic paper screen.

This size is equivalent to an A4 sheet of paper, reaching a resolution of 1280 x 800 pixels and can display up to 16.7 million colors, LG.Philips LCD said.

This is the highest resolution electronic paper screen ever developed, and is also a significant step up from the screen announced in May last year, which only displays 4096 color.

However, the amount of plastic mixed with specific glass depends on each individual product design. There are currently no screen types that can fold like paper in the right way.

LG.Philips LCD says the new 14.3-inch screen has borrowed some of the TFT technology it is using to produce LCD screens, then blends with metal and plastic compounds.

The result is a flexible screen that is less than 300 micrometers thick, which is a bit thicker than a standard photocopy paper. Even when bent, you can still view the screen with a full 180-degree viewing angle.

There are many defects

Although not as impressive as the 14.3-inch color screen, this product is easier to mass produce. Its plan is to release monochrome screens by the end of this year.

Besides the specs, one of the factors that determine the success of the screen is how fast the image is displayed.

An ordinary LCD monitor can change new images multiple times per second, but existing electronic paper samples take a few seconds to completely replace an image.

For example, the screen announced by Fujitsu in May last took 2 seconds to "refresh" an 8-color image, while the 4096-color image took up to 10 seconds.
