Hello everybody!
Today we tell you, friends, about the advanced technology from LG Electronics - CINEMA 3D. Our developers, LG Display, call it “passive” 3D technology. Why?
Read on.
Summary of the post:
1. CINEMA 3D: technological features, special glasses, lack of interference and flicker.
2. Application: how and on what devices it works.
Now, let's go into more detail about everything.
Technological features of CINEMA 3D
CINEMA 3D - 3D-technology of screens from LG Electronics. Many probably already heard such a term as FPR (Film-type Patterned Retarder).
With this technology (also called “passive”), two images are available to the viewer at the same time. And all this is completely safe for the eyes! The 3D effect appears without flickering. This has been made possible thanks to special polarized 3D glasses.
Read more about glasses below.
Where did the name CINEMA 3D come from? The technology owes its name to the 3D films that go to the cinema, and thus the first special glasses that were given to the audience (complete with a napkin, of course).
Officially, CINEMA 3D technology was introduced in May 2011. In the near future, the LG Display division plans to release 3D displays for which special 3D glasses will not be needed. This technology is called auto-stereoscopic.
CINEMA 3D: flicker-free image
Where does the flickering effect come from? In most cases, because of the glasses, and more precisely, because of the interaction of the glasses with other light sources. Studies say that 90% of viewers in Shutter Glasses 3D television notice flicker. The Japanese 3D consortium (there is one) even issued a warning that “flickering can lead to photosensitive epilepsy.”
In CINEMA 3D technology, flicker is completely absent. And thanks for that, again, glasses!
And CINEMA 3D allows you to watch TV without interference and more clearly, because FPR technology initially divides the right and left image.
Technological features of CINEMA 3D
Another advantage of CINEMA 3D is that the 3D effect is available to a large number of viewers, regardless of body position. With the usual LED-LCD television screens of the previous generation, you would not be able to watch TV in 3D lying down, but here you are. And all because of the increased viewing angle parameter (for CINEMA 3D it is more than 170 °).
CINEMA 3D technology is able to artificially increase by 4 times the frame rate - from 60 to 240 frames per second. As a result, the image is perceived more clear, realistic and vivid - especially in dynamic episodes.
2D to 3D
Turning any two-dimensional image (games, movies, etc.) into 3D with CINEMA 3D technology is no problem! What is the result of image conversion? Due to the clear contrast on the screen (between larger and smaller objects, their intersection, or due to different levels of brightness or clarity), which makes your eye perceive the image in different ways.
CINEMA 3D glasses
We already spoke about polarized (or FPR) 3D glasses at the very beginning. Glasses of this type allow you to view 3D images on any 3D devices from LG. Moreover, the same glasses (which, incidentally, are 10 times cheaper than active ones - their price is only 5-7 dollars) are suitable for viewing content not only on a TV, but also on a monitor screen, a mobile device and even a projector. This means only one thing: now you can enjoy volumetric content at home with the same level of image quality as in a movie theater.
And the good news for those who wear diopter glasses: LG offers several modifications, including a model that simply dresses over normal glasses.
At leisure, compare the models of familiar active glasses (Shutter Glasses) and CINEMA 3D glasses (FPR):
And also, which is also important - CINEMA 3D glasses do not need batteries and other energy sources, which significantly reduces their weight. In addition, with them you are not exposed to electromagnetic radiation, which is hazardous to health.
CINEMA 3D: CINEMA 3D TVs
- the so-called all-new LG TVs. Model names may vary by country. But still, the CINEMA 3D - LW code is included in the model name, followed by the sizes: 42, 47, 55 and 65 inches. Models with the DM code (also known as “Second TV” and - a little earlier - as “TV monitor") are available with a diagonal of 23 inches.
CINEMA 3D Monitors
CINEMA 3D is not only TVs, but also monitors with full support for full HD. So, for example, the D2342P-PN model supports low loading of a personal computer system and does not require additional elements for viewing 3D content. A set of glasses is attached to the monitor, as well as to the TV.
CINEMA 3D: laptops The
LG A520 laptop - the next model after the A510 - is known as the world's first personal computer with 3D technology. This model is available with a 15.6-inch screen with full HD support, a 750GB hard drive and an Nvidia Geforce 500 graphics card.
CINEMA 3D: how it works
Why is CINEMA 3D cool?
First, briefly about how the stereoscopic effect of a moving picture is achieved. Two images are superimposed on each other and projected onto the same screen through polarized filters in the opposite direction. A pair of analyzing filters (rounded polarizers in the other direction) are installed in the spectator’s glasses - again, in the opposite direction. The light, polarized on the left, is extinguished by the analyzer on the right, exactly the same thing happens on the other side. It looks something like this: A
3D CINEMA 3D image appears due to two diluted images and is completely safe, since the flicker is completely extinguished by polarized glasses. But we talked about this earlier.
In general, it is not surprising that audience preferences are on the side of FPR technology.
What do viewers choose
In America, 3D TVs were tested for image quality, the comfort of 3D glasses, the quality of 3D effects, during which a number of models were offered to viewers. For the purity of the experiment, the logos of the manufacturers were hidden. 80% of respondents preferred 47LW5600 - one of the TV models with CINEMA 3D TV, other convection 3D-TVs.
What users choose
Similar studies (though now no longer only in the USA, but also in Russia, Italy, South Korea) were also carried out for 3D monitors. We are pleased that 77% of respondents chose LG CINEMA 3D monitors.
Most participants noted that during the test, the eyes felt much better when working with these monitors, rather than with SC technology monitors.
Well, that's all.
It is clear that squeezing everything that we would like to talk about CINEMA 3D into one post is simply unrealistic. So, if you are interested in this topic, then Wellcome:
1. Beautifully and in detail about CINEMA 3D TVs here .
2. Visually about CINEMA 3D monitors here .
3. Read more about FPR technology here .
4. For those who do not know anything about the LG Display division, the link is here (attention, the site is in Korean / English!).
And finally, a couple of links to tests and news here and here (again, English).
Questions, discussions and suggestions on the topic are welcome (we are waiting for you in the comments). Well, if you already own any CINEMA 3D equipment, then we are waiting for your impressions.
Thank you for your time.
We hope they were helpful.
