CRT v/s Others!


Mainnu toh byali (42) inch da LCD chai da! – Dadi from Vicky Donor!
Laughed like crazy at that scene,right?
But do you know what is LCD? Stop acting smart! I am not talking about the full form. Liquid Crystal Display. We all know that along with the commonly known fact that “sirji,the display screen contains some kind of a liquid that is giving us a crystal clear display”, according to Govind Singh, from the electronics shop at Sarojini Nagar.
Is the LCD really “crystal clear”? Is it really an advantage over the CRT TV’s (Cathode Ray Tube).
The answer is surprisingly no! Reading deeper into the matter, its was realized that LCD do not really give the “crystal clear” display as it is claimed by Mr.Govind Singh! LCD screens are not clearer than CRT screens.
The LCD monitors are only good regarding the size, electricity consumption and sleek designs.
If the factors are changed to viewing experience, the big old fellas, CRT monitors are far better. The big backside screens provide clearer viewing. The colour range is wider and the resolution they provide is much more intense. And this is not some shitty research! We can ourselves experience that. Simple experiment. On a simple cable tv, watch the same channel, by the same cable operator, on a CRT and on a LCD screen. The LCD will definitely fall back upon the resolution and would show pixellated  motions. Further, if you use Standard definition digital tv signals on CRT, the colours and resolution effects are so pronounced that it can compete with the HD TV on your LCD.
Further moving on to the LED’s. Now, here, LED’s win the battle for sure. LED’s win the battle by more natural and vivid on-screen viewing. Watching a cliff-diver fall down actually rumbles your stomach and leaves you back with a smile about the feel of it!
The only drawback with LED’s is the cost of making, the electricity bills and the effect on ecology by the colour films used(RGB).
But here is the savior to the above drawbacks! OLED! The new guy in the family of televisions is the Organic Light emitting Diodes! And by the name we know that anything organic is good! OLED provides better quality with a duty to save the nature! OLED’s are made up of organic RGB films which provide more active ions to produce more eminent light emission. Organic polymers like dendrimers and triphenyleamine is used as the charge carriers for the diode (in this case, the holes).
It must be noted that OLED is still under testing stages and one must not jump on to it,like any other beta phase technology. It has been  found out that out of the three colour films, the RGB, while red and green are more lasting ( approx. working 46,000 hours and 230,000 hours respectively), the blue film has a very short life-cycle of just 14,000 hours.

CRT compared to all the above technologies seem far better with no hassles about the life-cycle of the colour films, equally good quality and the net production cost. However, the bulky cathode ray tube makes it lose the battle in the times of nano-technology, thus losing the market!

I have had opportunity to experience all the above stats and I own LCD, CRT and TFT screens myself. Additions and rectifications are more than welcome coz I am just a novice myself!
