Is LCD monitor better than CRT?

Question

I heard that CRT monitor affects our eye sight and LCD does not..Is this true..?If yes what is the reason?

Answer 1

that totally depends on your uses.

if you do  some kind  of designing  you beter use crt else you can use the lcd without any problem!!

Answer 2

LCD can save lot of space..better for eyes also..any way its better to change u r vision from any monitor every 20 min..continously looking into this will pain your eyes....

Answer 3

The old CRT monitor had very bad effect on your eyes.

But new CRT monitirs donot.

But still LCD monitors are bettter, in quality of pictures.

Answer 4

hi not only are LCD's much lighter, taking up less desk space, but they offer less glare as the screen is totally flat, the image is sharper the refresh works much better resulting in less headaches.

Answer 5

Yes exactly,

The CRT is rendering video with a high voltage current (lightnings) in 24 times X 1024 different pixels in a second so that u feels its a animated video but it contains a radiation that is 0.20% of "X-Rays" so watching an X-Rays is ofcourse affect eyes.

The LCD is using chemical technology which doesnt contain any high voltage rendering it has only normal white light (tube lights) for viewing.. so there is 0% x-ray or any other thing that can affect your eyes.

hope this helps

LCD monitors or Liquid Crystal Display monitors are replacing the old CRT or Cathode Ray Tube screens and are far superior in a vast majority of applications.

There are several advantages of LCD Monitors over the old CRT Displays. While LCD Monitors are compact and lightweight and consume less power approximately 20W whereas the CRT monitors are bulky and heavy consuming upto 150W. An LCD Monitor produces perfectly sharp images with perfect image geometry whereas in CRT the sharpness is limited and it tends to blur more at high brightness and with the aging of the tubes and suffers from geometric distortions.

LCD monitors have a consistent tonal scale and can display text with excellent contrast whereas the CRT monitors display strong bright areas which can cause other regions of the picture to dim and also has poor text contrast because of limited bandwidth.

LCD monitors do not normally flicker whereas a faint flicker can always be observed in a CRT monitor.

There are also some inherent disadvantages of LCD monitors over that of the CRT monitors. The contrast or the color changes with the viewing angle in a LCD monitor whereas in a CRT monitor it is always a consistent image irrespective of viewing angle. LCD monitors may cause motion blur and has a poor black on dark images. Whereas the CRT monitors usually portray motion well and also has good black contrast.

When viewing photos or videos on a LCD monitor it may appear flat and the peak brightness is limited by the back light. A CRT monitor displays movies/video/photos with a sparkle and life to images with very high peak brightness.

If LCD Monitor screens are damaged, it may develop stuck pixels whereas no such pixel based problems are present.

In LCD the natural interface would be digital e.g. DVI interface and the image can be sub-optimal with analog interface whereas CRT’s are naturally suited to analog interface.

On the basis of image-quality LCD monitor is best suited for technical/CAD applications and office uses such as large, detailed text-based but -non-critical color graphics while CRT still has the upper hand for high-end photography or art work and for television displays.

Unlike CRTs that are actively displaying the light through coated phosphors, an LCD actually takes white light and filters it to get the desired colors. To do this for each given pixel there are three sub pixels one for red, green and blue light. When the sub-pixel is off, the filter will block that particular color of light. When the sub-pixel is on, it will open the filter to let a desired amount of light through

Answer 7

Now i don't really know the reason but the thing is true. LCD doesn't strain ur eyes while CRT does. If u know CRT has a picture tube and has something to do ith radiation. LCD on the other hand consists liquid semiconductors instead of the picture tube. No radiation no problem. N they rn't that expensive anymore.

Answer 9

Both CRT and LCD would affect eyesight so there is really no way around it. If you don't want your eyesight to be affected, I believe the only solution is to never use your computer again. If you want to minimize the damage from the lights rays, don't stare at your screen for too long. Take short breaks every now and then, and look at farther away objects so your eyes will adjust to the light and not get fixed on the light from your screen. LCD is better because it is smaller and takes up less space. Plus it's easier to move around. And isn't convenience what most people prefer?

Definately!!

This question is actually much less valid than it was several years ago. Many companies have cut the production of CRT monitors except for the extremely high end and the very low end. In fact, most desktop computer systems sold now by default come with LCD monitors. Still for those that what to know the difference and which they would be better off purchasing, I have updated this article to be more relevant to the current technologies and products offered today.

CRTs

The primary advantage that CRT monitors held over LCDs was their color rendering. The contrast ratios and depths of colors displayed were much greater with CRT monitors than LCDs. While this still holds true in most cases, many strides have been made in LCDs such that this difference is not as great as it once was. Many graphic designers still use the very expensive large CRT monitors in their work because of the color advantages. Of course, this color ability does degrade over time as the phosphors in the tube break down.

The other advantage that CRT monitors held over LCD screens is the ability to easily scale to various resolutions. This is referred to as multisync by the industry. By adjusting the electron beam in the tube, the screen can easily be adjusted downward to lower resolutions while keeping the picture clarity intact.

While these two items may play an important role for CRT monitors, there are disadvantages as well. The biggest of these are the size and weight of the tubes. An equivalent sized LCD monitor is upwards of 80% smaller in size and weight compared to a CRT tube. The larger the screen, the bigger the size difference. The other major drawback deals with the power consumption. The energy needed for the electron beam means that the monitors consumer and generate a lot more heat than the LCD monitors.

Pros:

Multisync Capable

High Refresh Rates

Color Clarity and Depth

Cons:

Very Heavy and Large

Use Large Amounts of Energy

Generate Excess Heat

LCDs

The biggest advantage to LCD monitors is their size and weight. As was mentioned earlier, the size and weight of an LCD monitor can be upwards of 80% lighter than an equivalent dimension CRT screen. This makes it possible to users to have larger screens for their computers than was possible before.

LCD screens also tend to produce less eye fatigue to the user. The constant light barrage and scan lines of a CRT tube tend to cause strain on heavy computer users. The lower intensity of the LCD monitors coupled with their constant screen display of pixels being on or off produces less fatigue for the user.

The most notable disadvantage to LCD screens is their fixed or native resolution. An LCD screen can only display the number of pixels in its matrix and no more or less. It can display a lower resolution in one of two ways. Using only a fraction of the total pixels on the display or through extrapolation. Extrapolation is a method whereby the monitor blends multiple pixels together to simulate a single smaller pixel. This can often lead to a blurry or fuzzy image particularly with text when running the screen below is native resolution.

Video was problematic with early LCD monitors because of lower response times. This has been overcome by many improvements, but there are some that still have low response times. Purchasers should be aware of this when purchasing a monitor. However, the improvements are often work arounds that can actually lead to another problem of reduced color clarity. Unfortunately, the industry is very poor about properly listing the specifications for monitors to help buyers understand and compare monitors.

Pros:

Smaller and Lighter

Energy Efficient

Causes Less Eye Fatigue

Cons:

Blurry Images Outside Native Resolution

Motion Blur on Fast Moving Images

Some Models Have Reduced Color Clarity

Conclusions

At this point and time, most consumers will likely be purchasing LCD monitors over CRTs. There is almost no difference in the cost to consumers thanks to production improvements in LCDs and the reduction in the production of CRTs. Typically CRTs will only be seen sold with the least expensive of desktop computer systems or by those with special imaging needs such as graphics and medical professionals.

Answer 12

NO theres not like that if you are a professional in computer means u r working in a Advertising in a Advertising Field then CRT Monitor is not better 4 you but for home purpose u plannig to buy PC then i would tell you to buy CRT. because in Advertising field it is necessary to hv colour correction which u can do properly onl on CRT Monitor & also Some of the LCD Monitor are Not Crystal Clerar So if you buy LCD then it should ne crystal Clear Screen ok..Theres not like dat vch is d best 1 both are the Best at Their Place.Ok

Answer 13

yes liquid crystal display is better then crt monitor it is also provided better  or high resolution and it has no needed to space also

Answer 14

It's largely down to personal taste.  Basically you're staring at a light source which is not the best treatment for your eyes whether it's CRT, LCD or plasma.

Answer 15

CRT monitors produce radiation which may be harmful to eyes. But otherwise, staring at any monitor for long periods causes one's eyes to get tired and sore since the eyes muscles do not get to move.

Answer 16

TFT screens give out much less radiation and produce less heat. They also don't suffer from being left idle so your monitor doesn't need a screen saver either.

Answer 17

hey it's obviously true...............

Answer 18

LCD monitors are better than CRT monitors ..

LCD is the latest technology than CRT .. CRT monitors have become old now and consure more power and take lots of space ..

LCD are the best with less power consumption technology and good to look at and take less space ..

Answer 19

LCD are better because they resist at least 100 fraps per second but CRT monitors are cheap and biger

but they create so much radiation that they may hurt your eyes

LCD at 60mhz would never hurt your eyes never never!

good luck :]

Answer 20

Yes because there is no phosphorus or magnetic radiation off it, it uses less desk space, is better for eye strain and uses less power.

Answer 21

Yes.CRT has more radiation and gives eyesores.

Answer 22

Personally, I love my LCD monitors!  They are brighter without blasting your eyes, clearer and take up a heck of a lot less space.  

LCD monitors refresh faster and produce a lot less flicker which helps reduce eyestrain.  However, it's always a good idea to take a break every hour at least.  Look away from the screen, preferably at something in the distance, stretch those muscles in your neck and shoulders, do some wrist rolls and blink!  We all have a tendency to stare and our eyes will get dry.
