Samsung shows off 55-inch glasses-free 3D TV prototype and this 3D TV is able to accommodate nine different viewpoints for glasses-free 3D viewing and also can be switched into a 2D mode at any time which works by changing the optical refraction index of an LCD panel that sits on top of the main LCD……..

Samsung has a huge stage in the glasses-required 3D market and has a higher maket share thn all over 3D TV makers, has just demoed a new 55-inch display that doesn’t require glasses.It’s not quite a TV because right now all it can display is specifically tailored content and it has no TV connections. But that’s all stuff that could easily be added in. Getting the image to work right is the challenging part.Glasses-free 3D is also known by its more technical name of autostereoscopic 3D which is works by incorporating thousands of tiny mirrors into the display itself, so that images on a flat screen can appear to have depth.The new 3D LCD TV has a function to switch between 2D and 3D modes. The TV is equipped with an LCD panel whose optical refraction index can be changed in front of an LCD panel used for displaying images.The first LCD panel functions as a lens and shows different images to the right and left eyes. And when the optical refraction index of the first LCD panel is not changed, the TV shows 2D images.The specifications of the LCD panel for displaying images are as follows. Its pixel count, brightness and contrast ratio are 1,920 x 1,080 (full HD), 500cd/m2 and 4,000:1. It uses a direct-lit CCFL (cold cathode fluorescent lamp) backlight unit.
