Samsung's new LCD can display independent images on either front or back

When Samsung isn't making rapid advances in the area of memory technology, it's looking for ways to improve display technology. Samsung announced it developed the world's slimmest mobile LCD screen in November. The 0.82 mm thick screen featured a QVGA resolution and a 500:1 contrast ratio. Today, Samsung is showing off the world’s first truly double-sided LCD which can produce independent images on either side of the display.

Only a reverse of the original image data can be displayed on the opposing side with conventional double-sided LCDs. With Samsung's double-gate, TFT design, the LCD features two gates which operate each pixel instead of just one. This is what allows Samsung to produce two independent images. Amorphous Silicon Gate (ASG) technology also allows Samsung to manage the increase in TFT gates without a subsequent increase in driver ICs.

One backlight is shared between the two LCDs. The front LCD is transmissive and the opposing screen is reflective (which allows it to capture some of the light from the main screen). In its current form, Samsung's double-sided LCD is 2.6mm thick with a QVGA resolution. Brightness levels register at 250 nits for the front panel and 100 nits for the back panel.

"Our new double-sided mobile display underscores Samsung's commitment to equip our customers with advanced display technology that accelerates the trend toward slimmer mobile products. We anticipate high demand when we commence mass production in the first half of 2007," said Samsung Executive Vice President Yun Jin-hyuk.

RE: What use do you have for a double sided LCD?

Think of the laptop/tablet combos. Right now, you have to flip the monitor up, spin it, then fold it down backwards. Imagine having the LCD built into the back of your laptop panel where you just pop the cover off and you're good to go. Heck, you could even treat it as a second output. Even as a toy for say, business meetings, it could become whatever would be on the 2nd monitor.

Sure it has limited usefulnes. Cell phones are a good example though: already they have to cram two screens into flip phones for the top facing screen, now you could do it with just one, which will either thin them considerably, or give them more space to use for something else. :)

I can already see what people could do with this technology. Professors and school teachers and/or students with presentations could be teaching class, with the side pointing to the class showing lecture notes and examples. On the other side, the instructor would be playing F.E.A.R., which results in random interjections of swearing in between lecture points. Score one for counter-productivity.

Seriously, I think there will be some interesting uses of this technology. As a gamer, I can come up with a few more. Multi-player without splitting the screen is nice.

Thought of that to, but wouldn't the screen be a bit too small for lecturing?
