Samsung announces a double-sided LCD

Around the corner there are cell phones with a double-sided screen, one capable of showing an image and the second capable of showing a different one. To launch the Samsung component that announced a prototype of the product that will be marketed – according to the same Samsung – during the second half of 2007.

A double-sided display an absolutely original invention, something that so far failed to anyone: reproduce an image in front of it while projecting another on the back. So far, what the hi-tech industry had managed to produce was an LCD screen capable of reproducing the same image upside down in front of an image. The new development promises to replace two monitors with one, dramatically reducing – at the same time – the thicknesses.

In essence, what Samsung has done is the ability to drive two pixels placed on a double layer of film at the same time instead of just one pixel. In this way, each pixel can display a distinct data on the screen, obtaining two completely independent images. Samsung calls the transistor technology that allows this prodigy "double-gate", ensuring that the doubling of the "gates" allows the creation of more efficient, thin and less expensive products.

For now, the display format of 2.22 "ensures a qVGA resolution (240 x 320) on each face of the film. The primary screen has a brightness of 250 nits, while the secondary screen is only 100 nits. As for color saturation, the former has a capacity of 60% while the latter only 10%.

If someone, especially in Samsung, thinks, rightly, of the possibility of creating clamshell phones much thinner and lighter than the current ones (thanks to the elimination of circuitry and a display), someone else like those who can imagine things close to Apple that the features are compatible with various products in the mobile sector, for example a futuristic iPod or the new iPhone capable for example of showing a nice video on one side while on the other we navigate between one menu and another.
