Rewind to earlier this year, Samsung announced and demoed curved and flexible screen technologies. Back to the present and Samsung states they'll release a curved display phone by the end of October.
This isn't the first time Samsung has done a curved screen on a phone. In 2011 they introduced the Galaxy Nexus. This was the first phone with a curved display. Granted, it was curved so that when you placed it on your ear the curve would flow onto your cheek and closer to your mouth.
With the new curved displays coming out, they are OLED. That means each LED on the display is emitting it's own light and colors. With normal LED displays, a light source is placed behind them to display the colors and light.
We've seen curved displays coming to televisions to "immerse" the viewer. I personally think it's a gimick. Even on a smaller scale, it sounds kind of silly to me. I wouldn't mind a book like display. Imagine this, you have your phone and your surfing a website. Just unfold your phone size screen and you now have a tablet. How about this, a scroll. Think of unraveling a screen to watch or view something. It's truly remarkable.
We'll see what this phone is packing in the coming weeks. It'll be interesting to see it implemented in a consumer product instead of just prototypes.
