Today I will tell you the differences between LCD and PLASMA . Are you going to buy a television and is it LCD or PLASMA ? you can’t decide. In fact, I can say that we are undecided because we do not know the differences and working principles between LCD and PLASMA.. You know, I’m getting married, I’m going to buy a TV, I did a little research and let’s decide whether we should buy an LCD TV or a Plasma today..!
First of all;
What is LCD ?
LCD Liquid crystal is a semi-liquid semi-solid liquid substance discovered by botanist Fredreich Rheinizer in 1888.. After the 60’s, they found that the liquid crystals changed the properties of the light given to them by giving electricity from the outside.. In other words, when an electric current was applied to this material, the light could change.. Later, by placing this material between two glass layers as TFT LCD, screens began to be produced.. For example: Notebook screens are formed by changing the polarity of the liquid crystals by changing the intensity of the voltage given by this electrical current between the two glasses of the notebook screens, and thus, the screens that offer bright colors to our eyes by changing the intensity of the light.
LCDs give bright colors, so you can even get quality images. When you look at a natural picture on an LCD, the colors appear more vivid to our eyes because they are brighter.. LCDs do not vibrate thanks to these liquid crystal features.. Only CRT monitors (Old technology tube screens and TVs) have less reaction times.
So what is this reaction time?
LCD 2MS response time technology and New As I mentioned in my ASUS PG191 article, response time
So what is reaction time? The reaction time is the time difference between the displayed image and the next image.. The smaller this time difference, the sweeter the image.. It reflects so clearly and neatly. In the old-style CRT, that is, tube monitor technology, this is close to zero and even zero in some brands.
So you can see that the reaction time is higher in LCD monitors than in CRT monitors, so there may be some blurring in moving images due to the delay in the image.. Even though ASUS has produced a 2 millisecond LCD, I can say that thanks to the new technologies in these LCDs, it has achieved display perfection.. If you are going to buy an LCD, definitely ask about the reaction time and I would say buy an LCD with a response time of less than 8MS, that is 6 ms, 4 ms or 2 ms.
Features of LCDs:
Advantages;
- Low power consumption
- No vibration. so it doesn’t spoil your eyes.
- The image is clear and bright.
- They are small and light, they can be carried easily, and they provide ease of use with their small size.
Disadvantages ;
- Reaction times are low. (Of course, it will not be a disadvantage if you buy 2MS..)
- They have a short lifespan because the screen pixels deteriorate quickly.
- Contrast is low and viewing angles are narrow.
What is contrast?
Contrast is the difference between the brightest part of the image and the darkest part of the image.. If a screen, for example, has a bright white measurement of 100cd/m² and a black measurement of 1cd/m², the contrast is recorded at a ratio of 100:1. The wider the range of contrast between black and white, the better to see gray tones or intermediate levels between the two extremes.. The larger the better view..!
Let’s continue after a little explanation on this.
So to summarize ..
LCD …
The pixels die after a while. If you use it in a dusty environment, it gets hot. The cooling fan will absorb the dust and then it will start to make noise thanks to the dust accumulating on its shafts..! I recommend that you consider these. Of course, I can say that it attracts people because it has low power consumption, does not vibrate, does not tire the eyes and prevents eye damage.. In addition, these pixels are covered by warranty within a period of 3 years.. In other words, when your pixels die, you can replace your TV under warranty, there is no repair, so they have to give a new one… Or they will replace the screen, it costs the same for them…. In general, most of them have a PC input.. In other words, the digital connection system…..
Yes, I am summarizing the issue a little and I would like to give a few recommendations by saying if you are going to buy an LCD.
You went to a store and were lined up like soldiers. You’ve seen LCD TVs.. Beware, you’ll often come across images set in high resolution or with deceptive, purely selling animations, such as small aquarium fish.. Actually, I saw it in some stores, the same image is LCD and there is a PLASMA TV right next to it, I say look at these comparisons.. I recommend you to watch dark videos on LCD TVs and pay attention.. Because if you have difficulty in selecting the image in dark scenes and if the image is blurred at the edges and the vividness of the colors die, I would say don’t buy it.
In addition, I would like you to pay attention to the quality of this panel when watching fast scenes such as in the movie TOKYO Drift, as I mentioned above, if the image becomes blurry and blurry in panels with a long REACTION TIME, I advise you not to buy it.. But many manufacturers such as LG Samsung and SONY are making such improvements to this panel that they do not even feel such problems…
Let’s come to PLASMA TVs…
What is Plasma?
I can say that plasma is a different type of gas mixture consisting of equal number of independently placed electrons and positive ions.. If I’m more clear, I think you’re a little confused. A substance exists in 3 states. We learned that in middle school. What are these three states.. Here, plasma technology is another state of matter.. 4. We can say the state of matter Plasma state of matter… If you heat a gaseous substance to very high temperatures, the energy field electrons get rid of their nuclei and the gas turns into plasma.. In other words, when they taught in middle school, the matter did not have a plasma state, it has been discovered for the last 10 years as far as I know.. It actually existed, but they found it later
Although we rarely encounter the plasma state of matter on Earth, the plasma state in the universe has an overwhelming advantage over other states of matter in terms of excess.. Namely; It is thought that 99% of the total amount of matter in the universe is in the form of plasma.. For example, all stars, nebulae, and interstellar space are composed of matter in the form of plasma.. Quote: Bilgilik.Com
When electricity is applied to the substance in the TV in plasma TVs, the substance turns into plasma and begins to emit invisible UIV rays.. This beam becomes visible by hitting the GREEN, BLUE and RED phosphor layers in the TV.. With this method, I know that Plasma TVs are a completely different technology.
Each of the Pixels in the PLASMA TV is compressed with a special gas mixture.. There are Red, Green and BLUE phosphors in these plasma boxes, namely pixels, so that the image becomes visible with UIV rays.
Properties of PLASMAs ;
Advantages ;
- You can find plasma TVs up to 2.60 meters wide, this is the biggest one as far as I know, Panasonic’s new plasma
- They are light and take little space containers provide ease of use
- Can provide HD supported image quality.
Disadvantages ;
- Compared to LCDs image quality is low.
- If the same image remains on the screen for a long time, it sticks there and is not deleted.. ( I will explain this below )
- Power consumption is high.
- Their prices are expensive.
If you are going to buy a Plasma TV..!
LCD TVs have a history of 15 years. But plasmas have a much older history and I can say that their technology is well-established.. I can say that LCDs are more preferred because they are used in many technologies such as Notebooks.. Plasmas date back to the 70s, whereas LCDs have been used in TVs for 15 years…
Plasma TVs can reach up to 160 screens, while LCDs can be found up to 106 screens.. I don’t know what’s bigger, but it may be out, the technology is so hard to follow. Plasma screens can give a clearer view from the sides compared to LCD screens, so as I said above, the viewing angle in LCDs is bad on the sides, but plasmas give a better view from the side, that is, from different angles.
I recommend you to consider the following when purchasing plasmas. They are slightly heavier than LCDs, so if the place you will put them on is the wall, then you may need to use a stronger hanger or holder system. An LCD of the same size is much lighter.
The most important feature that separates LCD and Plasma television from each other is plasma. phosphor between plate and LCD is liquid crystal. The image angle in LCD is not as big as in plasma. In LCD technology, the image is much brighter than plasma.. While your eyes get tired after 1 hour on normal TV, your eyes start to get tired after 4 hours on Plasma TVs and 2.5 hours on LCD.. While LCDs fade to black, PLASMAs are much more successful in black.. You can get a much clearer image on Plasma TVs while watching a night shot video…!
But there is a much more important problem that I want you to pay attention to.
When a fixed image stays on the screen continuously in plasma TVs, the trace of that image remains.. So let me explain, which channel you are on while watching TV, the logo of that channel is always on the left, on the top or on the right, and this logo is fixed.. If you are constantly watching a match on your Plasma TV, do not be surprised if, after a while, you can see that the LOGO of LIG TV sticks to the screen..! In other words, this logo suddenly stays there and even if you change the channel, the logo will not be deleted and the picture will stick to the screen..!
Of course, I can’t say that this exists in every plasma, so the channel logo does not stick in every plasma, and there is no black fading in every LCD. .
Because technology is advancing rapidly and companies producing LCD screens are focusing on black and producing special solutions for themselves.. At the same time, PLASMA TV manufacturers are developing themselves and going much further on the sticking of the fixed image to the screen.
NOTE: If you are going to watch TV from 2 or 3 meters in the room where you will watch TV, you should buy an LCD TV. I advise. If you are going to watch TV from 3 meters away, that is from 4 to 5 meters, then I recommend PLASMA TV.. If you say I have a big space, I say choose Plasma, but plasmas get a little too hot, so you may need an air conditioner
Of course, Plasma manufacturers have to specially change the panels of LCD TVs despite the image sticking on this screen. Some companies have found different solutions on their screens, such as the technologies that allow the channel logos to be cleared after a while with white wash, and there are solutions that prevent the logo from sticking to the screen by activating the film filter and the screen filter when the logo stays on the screen too long.
