What is the difference between lcd and led monitor?

Computer Monitor LCD vs LED and TN vs IPS panels?

  • My monitor for the computer is starting to fail and i'm planning to buy a new one. I've been doing some research on whether or not I should get a LCD or LED monitor, many say that LED is better than LCD in many aspects including color ratios, respond time, energy usage and life expectancy. Even though the currently breaking monitor I have now is a LCD and the display is great and has been lasting for nearly 5-6 years. My main problem is actually the difference between a monitor with a TN panel vs an IPS panel, I found out about these 2 things during my search and it sounds to me like TN panels are the kind of screens that uses a smooth sheet of plastic as the screen's surface, while an IPS panel is one that has a nice glossy glass surface, am i right? The one that I've been using up until now has a glossy glass surface and I prefer this kind, because my dad has one with the plastic surface and when looking at it from the sides the color changes dramatically and I dont like that. I'm basically trying to confirm if "TN panel" and "IPS panel" is the right name in which to refer to the 2 differences previously mentioned before I go and buy a monitor online, due to the fact that the images they provide sometimes cannot clearly show whether the screen has a glass surface or plastic

    First I've gotta clear this up before we discuss displays, a lot of people get this misconception that LCDs and LEDs compete with each other. The thing is though that an LCD is the type of display, while LEDs are a type of backlighting. A display with LED backlighting will also have an LCD display so they don't compete with each other. For displays, there are CRTs and LCDs. Basically you can't really buy a CRT anymore so you have to buy an LCD. The only advantages a CRT has over an LCD is the framerate, though even now you can just buy a 3D LCD display that can display 2D content at 120Hz. Then the backlighting, there are CCFL (cold cathodes) and LEDs. There are two main differences with cold cathodes and LEDs, number one the amount of space they take up (LED displays are very thin) and the amount of power they use. LEDs use much less power than a cold cathode. LEDs are better to have and if you can get an LED backlit display for around the same price as a CCFL lit display it's worth it, though it's not something hugely important as it doesn't really make it look any better. And finally is the panel, there are TN panels and IPS panels. Honestly there is not really any point in getting a TN panel for a monitor right now. Pretty much every IPS panel display will look better than any TN panel display. Additionally, an IPS panel has a much higher viewing angle like you said, and if you touch it it doesn't distort the picture like a TN panel does, that's why every touch screen device needs an IPS panel. There are also very affordable IPS panel monitors out there, especially the ones from Asus. They're about the same price as other TN panel displays so they're a great deal. This is a great monitor: http://www.newegg.com/Product/Product.aspx?Item=N82E16824236122 There is also a 24" version on Amazon.
