Plasma or LCD - Big confusion

Plasma gives same contrast all the time(as long as you are not changing the contrast and brightness settings for different environment). You feel it different because of room light condition
Example : A man who is wearing white cloths in a white background room won't look contrast but if he will stand in a black background room he will look contrast. Mind it he had not changed his cloths but due to the environment change it looks like that.


There is an example image in bottom. Go to Image:Optical grey squares orange brown.svg - Wikipedia, the free encyclopedia for this image.

Here it is very similar what mandeep said. But actualy how our eyes react for colors. Both the yellow dots are having same value but upper one looks dull and lower dot looks bright because of Background. Please bare with me I will explain later the same thing from different prospective.

You can check the yellow dot's values in any software?
I am remembering those days when people were using one anti glaer glass sheet over there CRT computer monitor to decrease the brightness just to protect there eyes....

You are right.You are extremely right.I agree with you. But my friend here the TV itself is the light source and logicaly you are looking at thousands of tiny bulbs. If you are not using your tubelight and If you are planning to see things present in your tv room like sofa, table or remotcontrol or whetever in the light of your TV then that is a different case.
My friend quality of an image or video is not measured by vivid colors and crisper. As I told early an image or video looks more contrast and crisper because of less colors veriation present on them but at the same time you will loose the depth of image and information of image will be washed out. I wiil explain you later and if you want i will give examples.

Who enjoys laser show at 12 o'clock afternoon?
My dear friend again I agree with you but you are loosing the very need of good TV . Now you pushed me to explain the real theory of colors.
In TV we see 24bit color .8bit per channel.so accoding to that you can see 256 veriation of each primary color(RED,BLUE,GREEN).any totaly 256X256X256=16777216 colors.But many LCDs are having 6bit per channel.
Some clames our LCD showes 10 bit per channel. Means 1024X1024X1024=1073741824 colors .
The question is can you realy differintate them.As I told early an image or video looks more contrast and crisper because of less colors veriation present on them.
Now come to the same image we have seen in bottom

Its URL is Image:Optical grey squares orange brown.svg - Wikipedia, the free encyclopedia
Now suppose you have LCD TV and according to our eyes behavior we see the same yellow dot in dark room? It will look like lower dot.But the same dot will look dull in bright room light. So what if you want the LCD to display that dot in same intensity? You have to increase color value.
If the value of color was Red=250 Green=250 Blue=10
Then you can increase it till Red=255 Green=255 Blue=15 and you got the same dark room color.Right?
So suppose the value in dark was Red=255 Green=255 Blue=15
then what will you do? At this stage you cant go beyond it .And If you have two dots ones value is Red=250 Green=250 Blue=10 and others valu is Red=255 Green=255 Blue=15 then after increasing the color value both will look same because you won't get more head room. Here you lost variation and Image look crispy but lost details.That is were wahhed out theory comes.
If you say mine is 10 bit per chennel then what happens is it will not show you values from 1024 to 0. It will narrow the color veriation .
If value in an area is between 250 to 150 it will narrow it down to 230 to 170 so it will look crispy. MAN this is the theory which we you when we have to add or composit any special effect like spark or blast in any day light seen.
If you have a Ship sail that in sea not in small river.
So first understand where you should watch TV. In a bright room or in a dim light. And the main thing is LCD can't evan produce actual colors. Its red green blue looks like something different and so the overall color. Read my first post and do that experiment by your self.

In a dark room TV is having enough headroom to show you actual depth (If you are realy interested to enjoy)

I suggest you check your Input supplies for TV.

I can disscus whole day on that

I think you bought LCD .Don't you?
In my case I am using CRT.

except ur point for black levels, none of your point supports the LCD as all the other points including strain from anything tht focuses light in a room, even tht is there with a torch light too...

Now regarding your black levels point, then buddy your theory is not complete from the TV point of view...

if you know the technologies, then
LCD, works on the same technology as CRT, as it tool have backlight, and the when the rays from tht, crosses the RGB color panel chips, to the LCD Panel, then the dried up states of Liquid Crystals, expand them into pictures...

Where in Plasma, there is nothing like RGB chip, or backlight...
A Plasma panel is filled with Neon Gas, which in dried state has RGB color pallete with dried neon...
And when it gets positive & negative current from both the ends, they pat on the particular pixel, which thus expand the RGB color to make the proper color of tht pixel...and hence generated the picture...

Even now if u havent understood the theory.. then let me tell u...

In case of LCD, when the light is thrown through RGB panel, to the screen, to pixels, they have almost the same colors, so the number of colors go less... Though the contrast ratio is said to be the same, but more only because of the technology, and in that as well u require pretty bright ambience to get the proper view, as is there in Showrooms..

But, in case of Plasmas, the picture is generated on due to current charge on the pixels, so they can get as darker as they get the power, and as light as the power, as the RGB has all the colors of the Universe...
And where in homes, the ambience is totally different from the showrooms, the picture is clear, with much more colors than LCD...

anyone can put a LCD or a Plasma side by side and do this experiment...

Now, regarding the light in the room, tht the room, should nt be darker...in this plasma states much better than LCD..

as lcd technology has backlight coming from back, it directly get into your eyes, which annoys a lot, where plasma generates its own picture, so there is no problem with tht..

anyone can do this experiment as well..have a look at a Plasma in a dark room, then open the room lights at once..
Then do the same with lcd...
you will find tht, the lights while watching movies hurts a lot, in case of LCDs..

Bro, be practical on points, then be on theory..

Your theory is not wrong, but is in normal factor, but when its combined with other technologies the effect is different...

same as drug when taken directly kills, but when given as a medicine heals...

and yes sorry to mention..
what you are talking about contrast ratio is true..

the actual(native) contrast ratio is 1/25 time of the screen(dynamic) contrast ratio...

Its same as 1080i and 1080p...
where (p) refers to the Progressive/actual 1080 picture where (i) refers to interlace, tht means a 720p picture is being upconverted to 1080...

Same with contrast, the native contrast is the actual panel contrast but the dynamic contrst is what you see upconverted by the chip...

Mandeep Buddy

Thts nt the whole point...

The max problem than Plasma n LCD is from CRT...

the reason y LCD or Plasma is to be blamed, is as they have big screen, they have brighter light and hence they cause more irritation..

anyways what material, u talking about...
one should not tht the neon gas produce more natural and safe to view colors than crystals...
crystals always shine, and hence the strain on eyes are more, where neon gas is dull, so have all natural colors..

u must have observed in the showrooms, tht the lcd seems to be fine, as the bluntness of its brughtness is lowered down by the ambience lighting in shorooms, where a plasma seems to be very dimmer, and dull, in the same light...

and the ambient light what u r talking about is the RGB color changing light what Philips once provided in there lcds...
But it doesnt make sense anywhere tht the white or bulb light reduces the strain...

I am in the graphics industry for almost 10 years now and dealing with colors on a daily basis.
CRT monitors produce the most “ correct “ color. But most production nowadays even for animated movies happen on LCD monitors. CRT calibrated monitors are preferred only in certain very paranoid color critical industries.
For most practical applications like watching TV, occasional DVD and even Blu-ray you can just go in for Plasma or LCD depending on what your eyes like. If you are a purist video junkie with a perfectly lit home theatre room(ideal conditions) and watch only blu-ray and 1080pPS3 games of the highest production quality and are quite paranoid about true color-tone and such, then Plasma is the way to go because it is more true but for most practical applications Lcd is quite good. Half the graphic artists in my studio use LCD at home and have no complaints

..................

Well Mandeep, at least this proves what we all have been saying all along, that Plasma produce better real life pictures than LCD .

Ofcourse if you are someone who will buy a Tv set on face value and never fiddle with it one can buy lcd.

But for true picture and home theater lovers who want the bang for the buck and the best out of their set's plasma is the way to go, calibrate them and see the pictures come alive ...
