If so, LCD does less harm for your eyes but I feel nothing difference for staring between LCD and CRT. They do the same harm for your eyes when you are staring for a long time, I guess.
HI there, First answer is YES. CRT monitors do produce radiation, and ten years ago you could get a nice headache after working a whole day in front of one of them. However, you could buy add-on screen filters that eated up all that radiation. And lately, all CRT included already the filter coating at the outer glass surface You should not have problems if the monitor is new. By the way, some urban legends say that placing some plants near the CRT will reduce emitted radiation (any answer on this?) In all cases, higher refresh-rates (70Hz and up) for LCD displays will allow for a better, more relaxed viewing of the display, if you intend to work for hours in front of your PC Finally, some LCDs use white LEDs for backlighting. Depending on the technology used in the LEDs, some UV light might appear, but LCD displays do include some filtering, too Have fun!
hey i have been using both LCD and CRT but there is a slight difference . both will hurt your eyes if you stare on it for a long time but the effect with LCD is a little bit less . but the main difference between both of them is the heat radiation it produces CRT produces lots of heat and consumes alot of electric power and is vulnerable to causing accidents(fire) LCD has no radiation but the only problem it has is the flare (brightness) same as CRT my final conclusion is that LCD is better than CRT low -power consumption -no heat radiation -low desk space -portability
It will do harm to your eyes if there is no light source in the room other than the monitor, no matter what monitor you use. LCD does have less radiation than CRT monitors by the way, and use less electricity, and are a not a fire hazard like the CRT is.
I believe the strain on the eyes of the operators is much less when they use lcd monitors.
Yes, I'm in born myopic 'n I've recently undergone a laser surgery in left-eye since I've got a retinal hole in it. Doc has suggested for LCD monitor instead of CRT. If u've to remain in front of computer-screen for 6-8 hours, u'll feel a strain on eyes (both in case of CRT or LCD), but LCD provides lesser strain. If u prefer to use CRT then put on an antiglare sheet over the monitor. As far as difference b/w working principles of CRT LCD monitor - A CRT works by moving an electron beam back and forth across the back of the screen. Each time the beam makes a pass across the screen, it lights up phosphor dots on the inside of the glass tube, thereby illuminating the active portions of the screen. By drawing many such lines from the top to the bottom of the screen, it creates an entire screen of images. LCD displays use two sheets of polarizing material with a liquid crystal solution between them. An electric current passed through the liquid causes the crystals to align so that light cannot pass through them. Each crystal, therefore, is like a shutter, either allowing light to pass through or blocking the light. Color LCD displays use two basic techniques for producing color: Passive matrix is the less expensive of the two technologies. The other technology, called thin film transistor (TFT) or active-matrix, produces color images that are as sharp as traditional CRT displays, but the technology is expensive.
