Q. I wanna buy a 19" LCD monitor and currently weighing between HP and Samsung monitors. All HP monitors are called LCD monitors as per the package details as well as per their website, while all Samsung monitors are called TFT LCD Monitors. I am a bit confused, as I work a lot on PC, I would like to protect my eyes and health. Can someone help me with correct answer?
A. LCD monitors use Liquid Crystal Diodes.
TFT is an LCD monitor that uses Thin Film Transistor technology.
Other types are:
TN+Film - Twisted Nematic
IPS - In Plane Switching
MVA - Multi-Domain Vertical Alignment
PVA - Patterned Vertical Alignment
S-PVA - Super Patterned Vertical Alignment.
TFT is the most common today, and LCD is accepted as being TFT-LCD. Usually you only see a differentiation if it's one of the other technologies. The other types all have their advantages and disadvantages, but TFT is the cheapest to manufacture today.
For your eyes, you want an LCD. LCD's are on, and change when they change vs. a CRT which has a refresh rate. In a CRT, the phosphorus is charged and glows, but then dims very quickly. The refresh recharges it, but there is a dimming and brightening affect. The higher the refresh rate, the less noticable it is to you.
Within an LCD, if cost is no object, you want an IPS (better) or S-PVA (best). They will have the highest contrast ratios and brightest screens. Be prepared to pay, and pay well for this luxury though.

Should I wear anti-glare specs to protect my eyes while working on a LCD TFT monitor for long hours?
Q. Are LCD TFT monitors safe for eyes in comparison to the conventional monitors?
What should be done to protect the eyes while working for long hours on computer?
