Ergonomic comparison - LCD vs. CRT monitor screensNovember 18th, 2008 by admin
Technologically savvy and ergonomic product lovers are switching to LCD computer screens to complete their ergonomic workstation to reduce eye strain and improve their overall environment. LCD, which stands for Liquid Crystal Display, used to be a luxury for homeowners and big corporations. Technology has improved and the prices for these specialized screens have come down so much that your average Joe can afford them.
The first type of computer monitor screen was made from CRT, which stands for Cathode Ray Tube. This screen is becoming less popular because their color imaging isn’t as superior as an LCD screen. However, CRTs are still useful for displaying images with high pixels per unit area and with the correct color balance. CRT monitor screens are also still popular with those working in the broadcasting and printing industries, as well as those working in professional graphics and photography fields because of their greater color contrast and better resolution for displaying moving images. Apart from these industries, the average consumer is not in the market for CRT screens because LCD screens offer better features.
One of the other reasons that consumers are staying away from CRT monitors are the health concerns and claims involved with this product. Some researchers have claimed that electromagnetic fields are emitted by these monitors, which can have a negative effect on one’s living cells. Researchers have also proved that CRTs can release a small amount of X-ray radiation, but is considered not harmful. Lastly, CRTs are considered to be toxic waste when discarded, operate under extremely high voltages, and implosion may occur if the outer glass envelope is damaged.
Ergonomic LCD screens in the workplace are beneficial to workers because it produces a clearer image and helps to avoid eye strain. The reduced glare on the computer screen’s monitor helps to deter any eye injuries or headaches. A CRT monitor redraws the image on the screen when it refreshes, but an ergonomic LCD monitor screen only changes the necessary pixels when it refreshes. Ergonomic monitor screens are also void of flicker because they don’t work with a scanning electron beam. Flicker on a computer screen also lead to eye strain and a decrease in visual performance.
Ergonomic LCD monitors are also much thinner and lighter when compared to a CRT screen so it can be easily mounted and won’t strain your back if you ever have to move the screen. LCDs are also becoming increasingly popular, outside of the ergonomic workstation industry, because it requires less power per display area. Officials have noted that the energy use with an LCD screen is nearly 60 percent less than a CRT screen. Research has also shown that LCDs allow for better posture while working on the computer. Because the screen cannot be clearly viewed from different side angles, the screen helps to force the user to align their body with the front plain of the screen.
Overall, an ergonomic LCD monitor is more beneficial to someone working in an office because of the improved technology and better visual features that promote healthy eyes and posture. Be your own critic and test both screens out, but you may find yourself upgrading to LCD monitors in the future.
