So how do plasma TV's work? Believe it or not the concept of plasma displays had been invented as long ago as the 1930's, Not quite 21st cutting edge technology! The idea is that instead of using electrons to create lines, the plasma screen uses three fluorescent light cells, one in each primary colour.
Plasma displays are considerably shallower than older TVs, you can mount them on a wall and conveniently hide them behind a well-placed curtain. They can also be scaled up by adding more pixels and enough power to run them. The biggest plasma TV we found was a 152 inch! That's pretty much 3 meters long and will set you back a measly £380,000.
I bet your TV is not as big as 152 inches! If you enjoyed this vid then why not give us a thumbs up or share it with your friends.

But I also understand that plasma sets would scam 4 times per frame. I have seen the photos of this. I actually had a plasma set for a short time. I could almost see the 4scan operations to a point. When that thing fell over and split the screen, I powered it in immediately to watch the very center still try to produce at least part of a picture. If you wanted to see a grown man cry like a baby.😢 Mad respect to plasma because it was a crucial step in the development of flat panels and history of them.

Plasmas have a wider colour gamut and deeper blacks than LCDs, and at larger sizes they become more cost effective. You won't find many 32" plasma TVs, but as you go up in size they become more common, and at 60" nearly all the top models are plasma.

CRT's use Red Green and Blue phosphors to produce color. Scaling up the size of a CRT width wise did not proportionally effect the depth. Larger units weren't all that deeper than their smaller counterparts especially in the late days of the technology. Also RGB triads on a Slot/Shadow Mask display are not pixels as they're not individually addressed and not digital, they are analogue. Either way entertaining video.

But after 25 inches diagonal, it seems like every inch diagonal increase was a doubling of weight. Or damn close. 25" can be hefted up by one person. 30" requirements are 4 people to lift up. Wiider scanning angles made for shallower depth on CRT but as it got larger in the front, you're GOING to pick up more depth than a slightly smaller tube.

If you sit far enough from your TV to see the entire screen, you're unlikely to notice the difference between HDTV and 4K. Most live action "digital cinema" is mastered at 2K (4K is used mainly for effect shots that are going to undergo a lot of processing). You need a really good (read, really expensive) lens to get pixel-crisp 4K images. And remember that a Bayer sensor does not capture full RGB information for each pixel, but a TV screen does display full RGB information per pixel.

Then i realized that you NEED TO E AWAY from the screen far enough from close to 50" you need 1,5 to 2 meters distance. The burn in is something you forget about but happens all the time.. you wont notice , its only visible if you see a black screen or another one color screen. For the price of the Plasma fuzz and the burn in (which will be constantly overwritten so to speak) you get the best picture out there.

Color and image settings is all preference. There are so many calibration settings that it's all preference. What really sets tv technologies apart,is which one has the best black color definition,zero input lag,smoothest refresh rate,and most vibrant colors. Those 3 image qualities is what makes or breaks a tv or pc monitor. It separates the Alphas from the Betas. The videophiles from the tv noobs. As for motion performance,plasma tv is best in video game use,smooth buttery frame rate,and absolutely no input lag. This is very important in fast paced games,such as call of duty,no motion blur with Plasma.

Torque is the spinning power on the driving axel I think , so fwd or awd or rwd. Or maybe, torque is the combination of spinning power and weight of the vehicle. That's why it's easier to do a burnout with a vehicle that has more torque, because more power to the driving wheels and less weight to hold the car down.

There is in fact no absolute definition of "primary colours". It just means "the colours used as the basis of your palette". The only requirement (if you want to create a full spectrum) is that your primary colours be complementary to each other (i.e., every colour must be derivable from them, and the primaries should not be derivable from each other - otherwise your palette is unnecessarily big). Nearly all monitors use red, green and blue dots, but some types of film use different primaries.

Being LED-backlit does not mean they can turn off individual pixels, it just means they use an array of LEDs instead of fluorescent lights. Some use as few as 20 LEDs. Look at a big plasma vs. a big LCD in a brightly lit room (or even outdoors) and you'll see the difference in blacks. Nothing about plasma makes it "behind the times". The reason why most manufacturers prefer to push LCDs is that their profit margin is bigger. Same reason why CRTs vanished so quickly (very expensive to ship).

If I may answer.. combination of different colors of light gives you a whole new wave length of light, i.e another color of light. While combining different colors of pigments gives another color due to the reflection of the light on them to your eyes that gives the other color. so, the mechanism of color production if different.

The most famous one designed to improve typing speed is probably the Dvorak layout, but by then QWERTY and its variants (AZERTY, QWERTZ) were already widespread, and the advantage in speed wasn't enough to justify changing.

Actually, they don't give you a new wavelength of light, they only stimulate the color cones in the eye to make the eye THINK that that wavelength is present. We have three cones - L-, M-, and S-, that respond to the peak colors of R-G-B respectively. Pigments subtract from full reflection values, meaning they start with white and build up to black, SUBTRACTING R-G-B, making the primary pigment colors Cyan, Magenta, and Yellow.

Now think of the TV as a colored light projector you add Red and Green light you get Yellow, this is an additive process. However there is a TV that has yellow pixels also. It is the sharp quattron.

Light, unlike, paint or crayons, combines colors differently, which is why in an LCD or plasma display, which you would find in a computer or TV, each pixel uses red, blue, and GREEN, subpixels, not red, blue, and YELLOW. Yellow light is made by combining red and green light. You can easily see the individual colors of the subpixels by holding a magnifying glass up to the display, or more easily, by placing a small drop of water on the display.

It's either RGB which is additive (screen itself/background is black and all pixel at full intensity produce white) as you say or CMY (cyan, yellow and magenta) which is substractive (the screen produces white light by default and the colors are taken away/covered to produce the desired color) in a tv that's done with light filters. It's probably easier to imagine a printer which does the same thing; it covers up the white paper with ink. (usually CMY + black)

TVs don't work like print. Yes you start with white light, but then you turn it into 3 additive R G and B light sources with R,G,B filters. Then the three primaries additively mix together to show the entire spectrum. QD (O)LED does this a bit smarter, as instead of making white light first, a blue LED with a yellow phosphor to convert a part of the blue light is changed to a blue source where part is changed to red and green with a quantum dot film.

Well, for a large computer screen (ex., to replace 2 monitor), 4K can and does make sense, because it lets you sit close while still having good pixel density, and just have more space. On a PC you often focus on just 1/4 of the screen area, and you tend to lean back when watching fullscreen videos. With a TV, you're (nearly) always far enough to see the whole screen, and the image is limited by the stream / camera sensor / lens resolution anyway, so you gain very little from 2K / HD to 4K.

How poor this comment aged lol. I can easily see the difference between fullHD and 4K on a 48" from 2-3m.

@@nikoolix - Most people don't sit 2 metres away from a 48" screen. And the comment hasn't "aged" at all, because human eyes still have the same angular resolution, and both HD and 4K still mean the same (and a lot of "4K" content is still not _actually_ 4K, but hopefully that will continue to improve with time). If you compare two panels of the same type and generation, one 4K and one 2K (or HD), at a normal TV viewing distance, being fed the same signal, they'll be practically indistinguishable. As computer screens, the difference will be instantly obvious.

Whoever researched the background of CRT technology for this video didn't dig very deep. Tubes did become progressively slimer as time went on, of course nowhere a flat panel but still, and high definition resolutions were possible (full 1080i achievable on consumer HD CRTs/QXGA on CRT monitors). If CRT continued and didn't almost immediately die, more improvements could have been made.

They got slimmer and more shalow, but at the expense of extremely thick front glass. I've a B&O 32" true-flat widescreen CRT and it weighs 80kg. Net image size is 29 inch. That is NOT FUNNY. And it is still 55cm deep. Good thing is it turns towards the remote on a rotating feet, so you never see the huge back. A 80kg plasma would be like 90" or so and 10cm deep. CRT was on a dead end track. What DID happen is that Philips desigend a flat CRT tube in the nineties, in a flat glas panel with tiny electron tubes. But the project was killed by the board as it was too expensive. LCD was simply put too cheap to compete with.

Can't give you a definite answer as i only have LCD displays in my home. Plasma never really caught on in Ireland i don't think. Matter of opinion but i will note that plasma is vulnerable to burn-in like old CRTs were.

I find that on certain TV's the image seems to shake and it seems more realistic, but at the same time looks cheap. Is this due to fps? As older TV's don't do this.

You're probably thinking of TV sets that do frame interpolation (ex., to pretend that 25-FPS footage is 50-FPS).

Unlike most liquids, water expands when it's frozen. So, because ice is less dense than water, the gravity of the earth pulls harder on the water than it does the ice, and so the ice floats.

Wait, so a plasma screen emits UV light. Could you (in theory of course) get tan by sitting in front of a plasma screen long enough?
@RFC-3514
@RFC-3514 2 жыл бұрын
CRTs emit UV light as well. But (in both cases) it's a very small amount, and unlikely to have any effect on your skin unless you suffer from UV hypersensitivity.

LED TVs aren't backlit 1:1, and can certainly not turn off individual pixels. The black levels of plasmas are their biggest selling point for many, and are unrivalled by any LCD technology, LED or otherwise. I find plasma superior for movies, and am happy to be "stuck" on it...
