LCD and PDP TVs with three-dimensional image and the glasses are slowly becoming part of the household, but not as frequently as their manufacturers would have wished. It is worth the inconvenience caused by the need to use synchronization LCD glasses, so companies are trying to develop a display with a 3D image, which would not need these glasses. System for such a view exists but is currently limited to a smaller screen and a small number of observation angles, mostly a spectator must be directly perpendicular to the screen. Also the price is too high.
However, times are changing, Samsung introduced its new 3D TV without glasses. It is 55 “(140 cm) LCD novelty at the fair FPD China 2011th This TV has nine points, from which viewers can watch three-dimensional image with the optimal length of 2.5 to 6 meters. Full HD resolution is 1920×1080 points, the maximum brightness of 500 cd/m2 and 4000:1 contrast indicated by static. Used as traditional CCFL backlight tube, but according to Samsung, it can replace the LED diode (which looks better in marketing materials).
3D TV without glasses
Users can switch between 3D and 2D mode, and thanks to the use of two LCD panels – the first acts like a lens transmitting the image separately for the left and right eye, the second panel moth change the refractive index and hence to enable or disable 3D mode.
Potential applicants, however, have yet to taste a sample piece is just a prototype, and Samsung is not planning it anytime soon start to mass-produce and sell. Behind this particular high costs, according to Samsung will last for about three years before entering the market with 3D TV without glasses.
