Advantages and disadvantages of CRT display
Advantages: bright colors, large viewing angle, no moving object shadow, suitable for playing games. If Longguan is better.Disadvantages: large size, large radiation, visible area smaller than LCD.Recommendation: if you do not have crazy requirements on the screen, it is recommended to buy LCD.
I am upstairs to say, "there is a crazy demand for pictures". Ha ha, I used the Samsung 997MB+.In fact, those who buy a LCD who is one of the important reasons is fashionable. For most people, the factors than they have to not completely understand the data.
Radiation: the radiation of CRT is large, and LCD is not zero radiation. It's only much smaller than conventional CRT radiation.Color: CRT absolute advantage. LCD's best panel at the moment is 10bit, 16.7M. And CRT in this regard is an absolute advantage, in theory, unlimited color. So the current field of professional graphics still uses CRT.Refresh: since CRT is a tube light, so no matter how high refresh, has just reached 75HZ eye blinking, will obviously feel, while LCD is due to pixel directly display color, there is no refresh problem.Resolution: CRT, as long as the bandwidth is large, it can theoretically achieve unlimited resolution. Since LCD is made up of pixels, it can only have an optimum resolution, otherwise the difference display is very poor. For example, the 15 inch LCD panel is 1024*768 pixels, so the best resolution is 1024*768. 17 inches, 19 deposits are 1280*1024 pixels.Speed: CRT basically no delay. Similarly, due to the imaging principle of LCD CRT, CRT is luminous, the speed of light is needless to say. And LCD has response time problem, even if the fastest 2MS at the moment, there will be a shadow.Life: CRT life generally will be in 5~10 years, but there is an aging process in the middle, will slowly occur, focus is not allowed, brightness reduction and other issues. CRT life in 3~5 years, as long as the use of caution, do not force to stimulate panels, generally no problem.
