Samsung unveils double-sided LCD

News

Samsung Electronics announced today that it has created the first LCD panel that can produce independent images on each side of a mobile LCD display.

Samsung's double-sided LCD can show two entirely different pictures or sets of visual data simultaneously on the front and back of the same screen. Other conventional double-sided LCDs can only show a reverse image of the same video data.

This development could replace two display panels with one, thereby reducing overall thickness of mobile products by at least 1mm.

The product makes use of Samsung's new double-gate, thin-film transistor (TFT) architecture. TFT gates are electronic components that convert the necessary voltage at the pixel level, which in turn controls the liquid crystal alignment needed to reproduce on-screen images. Samsung's double-sided LCD has two gates that operate each pixel instead of one, so the screen on the front can display different images than the one on the back.
