Hello, I am happy to answer your questions!
This kind of monitor is bulky and not energy efficient. The picture tube display is called CRT and the liquid crystal display is called LCD. Both have their own advantages and disadvantages.
Radiation: CRT has large radiation, and LCD does not have zero radiation. It's just that the radiation is much smaller than traditional CRT.
Color: CRT has the absolute advantage. The best LCD panel currently is 10bit, 16.7M colors. CRT has an absolute advantage in this regard, and theoretically has unlimited colors. Therefore, in the current professional graphics field, CRT is still used.
Refresh: Since the CRT uses a picture tube to emit light, no matter how high the refresh rate is, there will be flickering. The human eye will not notice it as long as it reaches 75HZ. However, since the LCD displays colors directly in pixels, there is no refresh. question.
Resolution: CRT can theoretically achieve infinite resolution as long as the bandwidth is large. Since LCD is composed of pixels, it can only have one optimal resolution, otherwise the difference will be displayed and the effect will be very poor. For example, the 15-inch LCD panel has 1024*768 pixels, so the optimal resolution is 1024*768. The 17-inch and 19-inch LCD panels both have 1280*1024 pixels.
Speed: CRT has basically no lag. Also due to the imaging principle of LCD CRT, CRT emits light, needless to say the speed of light.... LCD has a response time problem, even the fastest 2MS will still have shadow.
Lifespan: The lifespan of a CRT is generally 5 to 10 years. However, there is an aging process in the middle, and problems such as inaccurate focus and reduced brightness will gradually occur. The lifespan of CRT is 3 to 5 years. As long as you are careful when using it and do not use force to stimulate the panel, there will generally be no problems.
