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?
This is a bit like a what's the difference between a dog and an animal? question. LCD means Liquid Crystal Display, while TFT stands for the Thin Film Transistors that are used to drive the LCD pixels. TFT's are ALWAYS used for this purpose, but some brands like to mention it as if it's something extra. There's no difference. LCD (as well as TFT) screens are far less a burden to the eyes as CRT screens are. because the liquid crystals are stable between refreshes, while CRT pixels are not. Therefore an LCD screen with a refresh rate of 60 Hz can yet be less tiring than a CRT screen with a refresh rate of 85 Hz. As long as the lightning of the room is comparable with the light from the screen and you look away from the screen every now and then your eyes should be fine.
there just different names for the same thing, you get no radiation from these type of screens
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.
