- 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.

LED refers to the new backlight tech used in LCD panels.
OLED screen are something else entirely: the pixels not only show colour but emit light as well. That means that darker images are actually using less energy.

Most plasmas can update at 400hz to 600hz with lightning response times (HDMI input to image displayed output) with which is much quicker then a LCD can handle and perfect for things like watching sport or gaming without juddering or lag.
It's actually possible to have colour TV with a single electron gun; it just needs to be able to adjust its intensity fast enough (i.e., in the time it takes it to go from each sub-pixel to the next).
yeah, like the Sony Chromatron
I think Techmoan reviewed a camcorder that had a viewfinder crt eyepiece with a single gun. It would use near uv pixel to synchronize the colors. It was red, green, blue violet. It had a sensor just for violet
RGBV, RGBV, RGBV, That's how it could orient itself to know when and where to burst. Techmoan actually showed us that when you covered the sensor, color was lost and monitor went monochrome.
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.
Been tem years since you said this.
@@hectormelendez4891 - And it still holds true, with OLED panels replacing plasma in the last few years. LCDs are still not a great choice for very large TVs (or gaming), although they're still a good choice for "work" monitors, since they don't have the burn-in issues that OLED has. But most people don't use 60" screens for work.
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.
I bought my plasma 65 inch TV and it’s yes it’s a Panasonic plasma TV 65 inch TV and 2009 and she still working perfectly today 2024. It’s way better than a lot of TVs today and mine has beautiful picture even when I’m playing video games, the colors are so vibrant and beautiful. I love Panasonic plasma. I have two of them.
Didnt even know I wanted to know how plasma TVs work, but now i know
Is May colour blind or is there an intentional error in every episode of HeadSqueeze? I've watched two so far and I think I'll let that be it.
Colour TV is composed of red, green and blue light.
lol
red blue and green pixels. red and green add together to create yellow. this applies to light emiting color sources. adding colors ultimately leads to white. color absorbing pigments work differently. for inks its red blue and yellow... adding colors in that case leads to black.
+Michael Rice Exactly
+Michael Rice
for inks you obviusly mean cyan, magenta and yellow, am i right?

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.
1:34 -- When I was a kid, I used to have nightmares about TVs chasing me around the house.
That brought back a whole lot of memories... o_o
This video had a brilliant start, an awesome ending and a very interesting middle - I love your channel :]

James May is the most brilliant man on the planet...
I submitted this idea to them on Facebook a while back! Can't believe they made it! :D now I'm just eating for a Head Squeeze shirt
+ JAMES MAY It is Red Blue and Green , not yellow. RGY are the primary colors, And Green is a secondary color. But why would they use RGB on a display? Well there is a difference in projected and reflected light. Where as RGY is used in reflective-subtractive color wheel. Think paint on the wall, where you add all colors you get black. 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. As the name would suggest it has 4 pixels Red Green Blue and Yellow.
You'll need a pretty expensive LED panel to match the picture quality of a mid-end plasma. But plasmas are heavy, glare is present, are potential to screen burn-ins and power hungry. If just care about the picture quality, look no further until OLEDs come out !
tv is made from primary colors(blue,red and yellow) all this colors can mix together to make secundary colors(green,orange and violet), from there you get tertiary colors...
really like the 50 inch Panasonic TX-P50S11B I picked up used on facebook last weekend its a great picture better than an LCD.
This is the funniest head squeeze yet. I wonder if May wrote any of the script
because of typing machines. they where first put in alphabetical order but letters that where used much where placed next to each other and because of that the letters got stuck next to each other and to make the machine as fast as possible the qwerty keyboard was made. a few letters have swapped places in the years after it was made but it is still mostly the same as in 1878. the M was next to the L and the C and the X where swapped.
A Laser TV requires lasers in three distinct wavelengths-red, green, and blue. While red laser diodes are commercially available, there are no commercially available green laser diodes which can provide the required power at room temperature with an adequate lifetime. Instead frequency doubling can be used to provide the green wavelen
QWERTY was made mainly to avoid having keys stick together, not to make it as fast to type as possible. 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. Same goes for Colemak, etc..
primary colours are red blue and yellow in paint, but in terms of light, it is actually red green and blue (indeed RGB).
green is not a base color since it is yellow and blue combined. Red, Yellow, Blue are, however i do believe many displays use rgb instead of ryb
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.
You are correct!
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 could listen to James May explain shit all day
It depends. LCDs are more power efficent, have thinner bezels and are thinner but have washed out blacks and are expensive. Plasma TVs are nowadays much cheaper, have excellent contrast and are brighter while also offering ridiculous 800Hz refresh rate excellent for fast movieng objects. Also great for 3D. They are heavier and thicker though. Also use much more power. Many home theatre enthusiasts will tell you plasmas are best, and they really are but mainly for home cinema, not watching tv.
MASSIVE amount of half knowledge here in the comments! I wish the video had ended at 0:16 with 5‘ of credits! Anyway that Snooker joke was sweet....
as, for example, in black-and-white television. This principle applies to a display as well as to a (front or rear) projection technique with lasers (a laser video projector).
In the future, sure. But the only 4k content available now is exotic rainforrest birds in slow motion type things that comes preinstalled on the device itself
Watching this on my Pioneer 508XD Plasma^^
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...
Those are secondary colours so they work better in absorption rather than emission. That's why they're better as inks for producing colour pictures on white paper.
No, It's actually Red, Yellow, and Blue. RGB is just another thing that like say Photoshop uses. But the primary colors, in which ever other color comes from are Red, Yellow, and Blue. Yellow and Blue make green
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.
YUV encoding, yes, but not reproduction - To generate a YUV signal you start with RGB, and to display a YUV signal you have to convert it back to RGB
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).
Why was the beginning so funny lol.
Mirrors are metallic surfaces. Metals have free electron in the outer shells of their atoms. This creates a sea of electrons that absorbs any photon entering it and re-emits it reversing its momentum perpendicular to the surface, but retaining its momentum parallel to the surface, so it appears to bounce off the surface like a pool bounces ball off the rubber cushion. This 'bounced' light fools your visual system into thinking there is are objects beyond the mirror surface, i. e. reflections.
nice vid
Most of it is UV, does it mean that I can get a very nice tan watching more telly? The coating of the cells can't filter all of it right?
LOL'ed out the start
I'll be sad the day my plasma dies as it looks better than any LCD tv I have seen. Even the top of the line LCD panels have uneven back lighting, with blacks that are dark grey at best. No amount of local dimming has fixed that.
There was a reason that Panasonic plasmas won all of the picture quality contests while they were still produced. I have high hopes OLED will take over the reigns from LCD and continue to fall in price.
red, blue & green james or additive colour. red, blue & yellow is subtractive colour
so what about LED and LCD tv's and how does Blu-Ray work?
Question - can I lay my 40" plasma flat screen up to make a virtual pinball , will it still work ?
James rocks!!!

DEVIN... GOOD INFO ! GRAMPS 2/16/16
hes such a lovley man x
Bring back plasma Tv's! These LCD and LED screens don't have good contrast. No matter which angle you look at them from, you can't see the deep black Plasma Tv's had.
this year oled tvs are in production they are the new thing by next year they are gana be affordable. the blacks are great because the pixel doesn't even need to turn on giving you the deepest blacks and less electricity used overall
JOHN JH IPS displays are a lot better, pretty much as good as a plasma
+Dan Reader Nope, I have an IPS monitor and a Pioneer Kuro Plasma, the plasma blows the IPS outta the water in every way possible. No contest.
+Dan P I have to disagree with that. I will admit you can still achieve better blacks with a plasma, but technology has advanced a long time since they stopped developing plasma tech. New IPS displays are a thing of beauty (and I mean quality ones, not the cheap £100 you can get from hannspree), with amazing viewing angles and awesome colour fidelity. Certainly plasmas are far from 'blowing IPS out of the water'.
Hahaha ok kid just the fact that you could make a Comment about "cheap lcd panels" without even knowing me tells me you know nothing, you've probably never even seen a pioneer kuro or even know what one is, but I would seek one out if I were you so you can see exactly how much better they are than the ips monitor I paid $500 for. Of coarse comparing a $5000 t v to a $500 monitor is a bit like comparing apples to oranges but I didn't bring up price you did.
please someone tell me the name of the tune in the end of the video

Shame it's now obsolete technology.
Plasma is not obsolete, it was just too expensive to produce compared to LED panels hence why they lost the market, Plasma is superior even to OLED in many ways, for one the motion resolution on a Plasma is still unmatched going 100% or if you have 1080p Plasma then it has 1080 lines of motion res whereas the largest a LED panel and an OLED can have is 350 lines at 60Hz, or 650/700 lines at 120Hz whereas Plasma can easily do 1080 lines at 50Hz or 700/800 at 30Hz
@@SMGJohn Plasma TV's are more expensive to run, easier to break and can have static images burn in. LCD and LED tv's are less expensive, consume less power and use better materials other than glass for their screens, making it harder to break. All of this made the technology obsolete.
@@SMGJohn Took recently to their plasmas Panasonic and LG-pioneer LX508d -it's just amazing. Modern plastic TV plasma is not a competitor.
