What is the Difference between LCD & LED Monitor?

Couple of years ago, giant monitor manufacturers declared that CRT (Cathode Ray Tube) monitors will no longer be available in the market as it consumes heavy power produces low quality output and most importantly better technology is available I mean LCD Display.  

CRT Monitor was the only one choice of customer for a long time. Then LCD overthrows it from the market. But LCD's time was too little. Within a very short time another technology that is LED has arrived and the time of LCD is almost finished now. 

Many people are often confused with the two terms - LCD and LED. As they look same, both are thin and smart so many people can't make a difference between the two. In this post I wanna clarity the difference between the two. 



LCD Vs. LED Monitor: Basic Difference
LCD (Liquid Crystal Display)
LED (Light Emitting Diode) 

LCD and LED monitors are based on the same basic technology for image display, but differ in case of back-lighting technology used. While LCD monitors use cold cathode fluorescent lamps for backlighting, LED monitors use light emitting diodes. This is the prime difference between the two display technologies. 

So, to be honest, LED monitor is the improved version of LCD. 

LCD displays have to rely on external lighting, as their display is created through manipulation of light, passing through polarized liquid crystals. The back-lighting affects picture quality substantially and light shed by LEDs offers superior picture quality, compared to LCDs.


This is because LEDs offer much more gradation in intensity and a larger light wavelength spectrum, giving a truer color quality. These types of monitors offer a better dynamic contrast ratio too. So if you compare LED vs. LCD monitor for gaming and other intensive graphic applications, LED monitor is surely better choice, as they provide vivid and more natural colors, with better gradation.

One of the basic problems of LCD is that it can't display true black color. But LED can produce true black color by entirely switching off LED.

LED is somewhat slimmer than LCD.


LCD Vs. LED Monitor: Power Consumption

LED is a very recent as well as latest technology. They are preferred over LCD Monitors due to its overall high quality and less power consumption. It consumes much less power than LCD to operate. 

LED monitors consumes as much as 40% less power than conventional LCD monitors. 



LCD Vs. LED Monitor: Durability

LED Monitors are Eco-friendly as mercury is not used in their production. Since LED produces less power output over time, so they are more durable than LCD monitors. 



LED Vs. LCD Monitor: Cost

This is the one and only factor that holds back LED Technology. I mean the LED monitors are little bit costlier in compared to the LCD monitors. The difference is also not so high. However, the cost gap is lowering gradually with time as the demand for the LED is increasing. 

Note: Most of the today's laptop producers use LED display. And almost all laptops' screen are now built with LED technology!

    I Think you mean "in compared to the LED monitors" = in compared to the LCD monitors.

    I am a graphics designer. Call me stupid but I still prefer CRT monitors for graphics design. Because both LED and LCD produces somewhat dimmed version of the real colors. And moreover if you look from an angle both the screens will have some de-saturation (discoloration). And this limitation would hamper to see the true color for an image.

    BUT... for entertainment purpose, household PCs and for portable devices (such as laptops, notebooks) I prefer LED screen. It provides a lighter look, weighs less and displays crisp text.

    So nice of you to write about it Munna! Thanks.

Joining Texts from Multiple Cells in Excel

  Programs like MS Excel is full of functions. There are many useful functions that we don't use or we don't know about. One of them is CONCATENATE. It means joining or linking. With this function you can join texts from multiple cells. Let's see how . . . Suppose you're working in an Excel Worksheet where you need to combine texts from different cells. I'm gonna show you an example. Let's consider the image below -    What do you see ? I've imputed First Name and Last Name. In Full Name column I've used the formula i.e. CONCATENATE. And in the last column I've added Mr. with the full name.    So how do you use this formula ? Here it is -  =CONCATENATE(A2," ",B2) Observe it carefully. You can add more than 02 cells with this functions. Here I've just used 02 cells. You may think what is this " " for ? You may notice that there is a space between the two i.e. " & ".  If you don't use " " then you...

Running Total/ Cumulative Sum in Excel

  Hey Guys! You should have noticed that I'm writing on MS Excel for last few days! To be honest I'm trying to learn some simple and useful tricks of Excel. And I'm also trying to share my knowledge with you. In this post I've come with such a little trick which maybe very useful if you face such situation. Let's begin . . .    Running Total/ Cumulative Sum It means the summation of numbers in a list and it will be updated each time when a number is added or changes. Look at the image below -    Look at the image. There are two columns with numbers. The first one is simply the number list. But the 2nd one is the summation of the list. Each time a new number is added to the first column the second one shows the summation. How to do this?  It's not a magic. Very simple sum formula is used to perform this task. But there is a little trick. You just need to lock the first cell and then every time it will update the running total list.  Here is my list. Sim...
