Now the production of 3D TVs is discontinued, but before the manufacturers in the technical specifications could only mention that the TV supports 3D. But they could not say what type of 3D the TV supports. Your TV will automatically determine the format of the recorded 3D image and display it on your screen. Unless of course it supports this type of 3D display.
Nevertheless, some manufacturers specify type of supported 3D image. As an example LG specifies (SG/FPR/AR/GPR/Non-Glass) what it is and what these abbreviations mean.
SG – (Shutter Glasses) explained
SG – (Shutter Glasses) shutter glasses, in other words, active 3D. This technology is used by Samsung, the viewer is shown separate frames for the left and right eyes. The glasses are alternately dimming the glasses in sync with the display of frames on the TV. The disadvantage of this technology is that the number of frames decreases by exactly half when displaying 3D images. Also, such 3D is very tiring to watch, the reason is unnatural for the human brain perception of such 3D. As practice has shown, such 3D is available, but not used.
FRP – Film-type Patterned Retarder explained
FRP – Film-type Patterned Retarder-a technology it uses circular polarization LG, the viewer sees the image through the cursive one image for the left and one for the right eye. In this case, the TV screen is applied polarizing film, polarized glasses also so that each eye sees only its image.
AR -Augmented reality explained
AR –Augmented reality It is implied that the TV can convert 2D to 3D and generate a 3D image. Yes, at one time TV sets were able to do this, but for such a mode it was necessary to have a rather high quality original image. The generated 3D image was not of high quality.
GPR- Glass Pattern Retarder explained
GPR– Glass Pattern Retarder similar format to FPR, only the screens are made with slightly different technology, the founder of AUO.
3D Non-Glass explained
Non-Glass – 3D images are created for playback on glasses-free devices. 3D images are created for playback on devices that do not require glasses. Several companies have been working in this direction. Toshiba even released a 3D TV that you could watch without glasses. But its cost was very high and the picture quality was mediocre. Further research in this direction was stopped.
Let’s say for the viewer to know these technologies is not necessary, since 2015 the production of 3D TVs was discontinued, due to low demand for 3D movies the inconvenience of viewing in the home. 3D TVs were slightly more expensive than similar TVs without 3D, and the buyer very often opted for a cheaper TV. 3D has survived only in the theater, 3D movies in the theater are more adaptable and cause less discomfort to viewers.
