Samsung has produced the biggest ever flexible LCD panel.

The latest prototype comes in at seven inches, and offers 640 pixels by 480 pixels resolution. The previous version was five inches.

The panel is based on amorphous silicon TFT technology, which is a common manufacturing method for LCD panels. However unlike conventional LCD panels, made on sheets of glass, this panel is made on a sheet of plastic so it can be bent into various shapes and is also more durable than a traditional panel.

For the new panel Samsung refined the manufacturing method so that the TFT panel and color filter - the two major parts that go together to make a display panel - were attached together. This minimizes distortion that can occur when the panel is bent should the layers not be attached, said Chae.

Samsung hasn't determined a schedule for sale of the panels. "We're considering the market situation. We don't have a specific plan at the moment," said a spokeswoman.
