In older times CRT computers and TVs were ruling all over but then came the era of LCD Monitors and after LCD came the LED Monitors. Similarly new changes were gradually made to all these technologies. As we all are familiar to this that technology never let electronic devices rest for long time eventually new thing do replace the previous ones. But somehow the changes made to these monitors were actually blessing in disguise, like the latest monitors like LCD monitors and LED Monitors are less harmful to eyes as compared to the old CRT Monitors. Yet there are some differences in these two latest displays regarding functionality and quality as well. First of all let me tell you that what LCD and LED are. LCD stands for Liquid Crystal Display where as LED stands for Light Emitting Diodes. When the LCD monitors took place of CRT ones people were amazed to have such monitor which has some kind of gluey jell inside the display panel. And amazingly this LCD technology also has great view mean the bright color and realistic output fantasized more viewers towards it. As I mentioned above use of LCD made less harm to our eyes as compared with CRT monitors as it emits less radiation.

The very basic difference between LCD monitors and the LED monitors is that the LCD monitors used Cathode fluorescent lamps where as the LED use diodes which emits light in several colors at a certain point. These diodes functionality is quite simple, when the electrons reach a specific wavelength of charge a light is emitted and hence each color has its own emitting point which is usually set by the manufacturers so that all colors could be displayed easily. LCD monitors were actually based or you can say a derived version of CRT technology as CRT monitor had to make their own light similarly LCD also had to rely on the liquid substance which was filled in it. When the light passes through this liquid jelly type substance different colors were produced. But the drawback of using this liquid was that when the liquid gets damaged or dry out or may get a part the image in that specific area would not be displayed rather a big black spot comes there. Unlike LCD monitors LED monitors and TVs are much better although these LED are also considered as an enhanced version of LCD but yet much better and more efficient. LED monitors don’t rely on any other thing rather they have their own system which makes them give the best output. The good thing about this LED technology is that they consume less power and they are much cheaper as compared to other displays.

These days Touch screen monitors are quite in at the market but affording such type of monitors suddenly become little hard. Although if we look around ourselves we do find this touch screen monitor type devices a lot. Like our smart phone, Tablets, touch screen mobile phone hence the conclusion is the same that the technology keeps on changing and brings such things to us which we never thought of.
