Samsung Electronics Co Ltd exhibited a 55-inch 3D LCD TV viewable with the naked eye at FPD China 2011, which is taking place from March 15 to 17, 2011, in Shanghai, China.
When a 3D image is being displayed, the number of viewpoints is nine, and the optimal viewing distance is 2.5 to 6m.
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.
“This is just a prototype,” a Samsung staffer said. “We can replace it with an LED backlight unit.”
As for when it will be commercialized, the staffer said, “We have not decided it yet, but it will take about three years to commercialize it.”
