Cathode Ray Tube

In the expensive professional CRT-monitors refresh rate has been achieved up to 100-120 Hz, at which the eyes do not notice the flicker. In view of the LCD-monitor features implementation of brightness may also be present flicker, albeit at a fairly high frequency of 200-400 MHz. This flicker can sometimes weary eyes with a decrease in brightness. But the flicker, you can usually get rid of, reducing the brightness in the settings of the video driver, not the monitor. Complete withdrawal of the image. The principle of constructing an image that is used in CRT-monitors, significantly different from that to which our eyes are accustomed to.

In the LCD-monitor image appears already formed in his eyes and easier to perceive. Lack of distortions. In the LCD-screen image is formed not as a crt. Even in the flat cathode ray tube CRT-monitor is needed correction of geometric distortion arising, again because of the peculiarities of constructing an image. To read more click here: Jack Smith. LCD-monitors do not have this drawback. And in the settings of LCD-monitor, you will not find such adjustments, they just do not need.

Clarity image. Another advantage of LCD-monitors should be considered as high-definition images, unattainable in the CRT-monitors. According to reports in the forums when users change the CRT-monitor on the lcd or even reduce the sharpness of the image, eyes to quickly become accustomed. Brightness. The level of brightness LCD-monitors are already too caught up and even overtaken CRT-monitors. Many writers such as John Krasinski offer more in-depth analysis. Today, even low-cost model of LCD-monitors can achieve brightness of 300 cd/m2. These figures are not available to all CRT-monitors. The absence of radiation. Cathode Ray Tube CRT-monitor emits electromagnetic waves. In principle, the radiation of modern monitors is at a safe level, but the LCD-monitor does not radiate, therefore still more secure. Power consumption. Modern LCD-monitors consume 60-80% less electricity than CRT-monitors. Perhaps, this advantage will appreciate the users who need a computer set its time. Conclusion. Proceeding from the above, one might get the impression that lcd technology does not have flaws. This, of course, is not and LCD-monitors have their drawbacks. But while the production of monitors cathode-ray tube is reduced, lcd technology developed and are known for their shortcomings, as the response time or a small angle, are becoming less relevant. And a large number of parameters of LCD-monitor all more and more superior to crt. And if the designers still prefer a professional and expensive monitors on the cathode-ray tubes because of their high-quality color, the majority of other users, both in office and home are increasingly leaning toward an lcd. And I think the advantage to the side lcd will only increase.
