It’s been a while since I’ve update my blog, technology wise. Thanks to an increase of traffic to this here blog I decided to give you some details on a popular search (something I vaguely posted previously). Bezel-less TVs. It’s a geek’s wet dream to have a few of these mythical pieces of hardware. However, we are getting pretty damn close thanks to two things in particular: glass and LEDs. We’ll go over those as well as 3D technology and TVs you might be looking for.
3D has been around for a while, but it wasn’t until this last year that 3D technology has progressed. You remember the good ol’ 3D days? Blue and red lenses held by that familiar cardboard frame. Oh the joy of having the cardboard dig into your nose and ears. Not to mention the wonderful headache after 2 minutes of watching anything. By the Beard of Zeus! 3D glasses were the best invention of all time! But Alas! Anaglyph 3D has been replaced by its sexier younger sister RealD 3D. RealD is based off of an advanced version of stereoscopic 3D. The lenses range from a clear to smokey color. Best part of all is that both lenses are the same color! The way RealD works is by taking two cameras and filming from two different angles. Each angle is meant to represent how each eye sees. The degree of the angle between the two cameras translates over to how your eyes convert the depth of the image. In basic terms its the difference between having a ball sitting on a table or a ball flying at your face! However its still not perfect. I’ve learned that the quality of the 3D image is still dependent on how the TV projects these two images and in turn how the glasses receive those signals. We are definitely progressing though! Thumbs up for that I suppose.
LED TVs came out just a little before RealD 3D did. This innovation has really pushed the television market into more of the HD realm than it ever was before. LEDs have also been out for a while as well. They have been used in electronics as button lights and so forth for a long time. Advance flashlights used LEDs instead of bulbs providing a longer batter life and in some cases more even and brighter lighting. Let me digress no further and delve into how LED TVs work. Lets get one thing straight to begin with: LED TVs are still LCDs. The difference is the back-lighting system and how it works. LCDs vs LED LCDs is the difference between florescent back-lighting and LED back-lighting. Florescent lighting is usually accomplished using florescent bulbs; similar to the ones you have in offices but much, much smaller. So small in comparison that they are installed on the sides of the LCD inside the bezel of the TV, lighting across the screen. LEDs have been installed in the same way as regular LCD back-lighting, but LEDs are brighter and can be made down to the size of grain of sand if so desired. “How the hell does that improve the lighting?” I know you wondering and even asking that out loud (despite the strange looks the other people in the coffee shop are giving you). Well question aloud no longer! Think about it, if you can make a tiny little square that puts out a high amount of light couldn’t you line the edge with a bunch of LEDs? The answer is yes! Yes you can do exactly that! Manufacturers are doing just that! The reason this pushes HD farther along is because the lighting provides more of a contrast! Now I know what your thinking, “Holy Fat Buddha, that’s amazing!”. Indeed it is… indeed. However if you have ever gone shopping for LCD TVs (and I sure hope you have if your searching for bezel-less ones) then you know that the bigger the screen the higher the degradation in quality. This is because florescent bulbs have a short range of lighting. Now don’t me wrong here, LEDs don’t produce infinite range of light either, but because LEDs are so small (or can be made “so small”) then this allows you to take a different approach. Now it gets very technical here so hold onto your car-seat; If you take two equations and kinda intermix the two using the range measurement equation of the Global Positioning System then you could…………. alright, alright I’ll just spit it out. It’s called Full-Matrix lighting. Instead of the LEDs running along the edge of the LCD they are instead lined up behind the screen. That’s right, I said behind. If you think a bunch of LEDs lined around the edge of a screen imagine the lighting contrast you could achieve with a full sheet of LEDs in the rear! Mind boggling I know. Hold on just a second longer for me now.
Glass. Something so simplistic and beautiful. Have you ever seen a iMac before? Check it out at Apple’s website. I really would love to have one. What does that have to do with glass? Well Apple has used glass on its iMacs. giving it a pleasing seamless look. Not only does this protect the LCD screen itself it also allows bezels to be invisible if done right. There is still a bezel on the iMac of course. There is a way to attach the glass directly to the LCD eliminating the need for a bezel, I however can’t think of who has done this. If you know please comment on this post and I’ll add it in because it’s really bugging me. Anyways, I see this technique as a way to create actual bezel-less screens.
Now to move on to the final portion and that is showing off some damn slim and near bezel-less TVs as you will get at this particular moment and near future.
Lets start off with the only one that isn’t out just yet and that’s LG’s new 3D TV. Now before you piss your pants in excitement I just want to give you a forewarning: If you don’t like 3D (which I’m not very particular about myself to tell you the truth) these few TVs are 3D. “What’s good in that?” Don’t worry 3D can be turned off, but it’s there if you want it.
With out further ado I present the LG Cinema 3D TV 55LM9600. Its absolutely gorgeous! 55″ of super slim 1080p. Just get a look at that bezel! It almost appears as if the screen is just being projected from space (avoid focusing on the stand)!
Now here is one that is actually available to buy. It’s made by Samsung and is on par with the LG, but one thing I can see Samsung having over LG here is picture quality. Samsung does a damn good job of producing large scale TVs that project the same quality as their smaller ones. LG is newer in the market and when looking at other things they produce primarily (smartphones) I am not impressed with them as it is. Here it is the Samsung UN55D8000YF: This is the 55″ model. Samsung makes 46″, 55″, and 60″ versions all roughly $200 in price difference.
There is one more and it is made by Sony. This TV is not bezel-less but they use glass just like Apple does. Here is the SONY 40″ BRAVIA NX720 LED 3D TV:
Thats all thanks for reading!
