LED vs LCD Screens Explained

LED vs LCD Screens Explained

The TV viewing experience today has become even more exciting with the launching of several television models and features. LED and LCD TVs are the two best options you can choose. But if you’re still wondering which of these two is perfect for your needs, this guide could be of help.

In this guide, we’ll walk you through the differences, features, and usage of these two types so that you’ll know what LED transparent screens and TV size to buy.

A Quick Look at the Origins of LCD and LED


It was the studies of H.J. Round on electroluminescence in 1907 that paved the way of the discoveries and innovations related to LED. And in 1927, Oleg Losev created the first LED. It was George Destriau who discovered that electroluminescence could be generated by suspending an insulator containing zinc sulphide. Since then, countless experiments had been made until Monsanto mass-produced LEDs in 1968 for the first time.



The origins of LCD can be traced back to the studies of Friedrich Reinitzer in 1988 about liquid crystals present in cholesterol extracts of carrots. In 1962, Richard Williams, an RCA researcher, applied voltage to thin layers of liquid crystals, which made it possible to control the light reflections on the crystals electronically. James Fergason invented the improved version of this tech in 1969 and used this tech in watches.

LED and LCD Features Comparison Chart

Check out the comparison chart below for the key differences between LCD and LED TV.




Acronym Meaning Light Emitting Diode Liquid Crystal Display
Types LED TVs also come in 3 types based on how their backlighting mechanisms are made:

a.    Full-array LED

b.    Edge-LED

c.    Dynamic RGB

LCD TVs come in 3 types:

a.    Rear Projection LCD

b.    Flat screen

c.    Front Projection

Power Consumption Unlike traditional TVs made with cathode fluorescent lamps (CCFL), the LED TV is well-loved for its energy-efficiency. Users can expect a 20 to 30% power savings with this product. Power consumption depends on the screen size. A 30-inch LCD TV uses 60 watts, while a 50-inch screen uses 150 watts.
Screen Size Up to 90 inches 13 to 57 inches
Life Span Approximately 100,000 hours Approximately 100,000 hours
Thickness LCD TVs with LED edge backlit are thinner than CCFL LCD TV by 1 inch. At least 1 inch
Picture Quality The same kind of screen is used for LCD and LED. Hence, the difference in picture quality depends on whether the model uses a low-end or high-end screen.
Backlighting Available for both TV types
Switching Time Fast Low
Resolution High Low
Contrast Ration Low High
Usage Both technologies could be used for viewing traditional television channels and display advertisements.


Before you hit the store to buy either an LCD or LED TV, be sure to list down all the features you want, as well as your preferred screen size and usage. Then, set a budget. Remember, the cost of both TV types depends on these aspects.

A Closer Look at the Screen Technology

Although these two technologies have a lot of differences, LED and LCD TV screens are quite similar.

A Quick Look at the Origins of LCD and LED

LED Screen

An LED screen is just another type of LCD screen. The only difference is it has light-emitting diodes or LED for its backlight, instead of CCFL components. It comes with a panel that consists of two sheets. The sheets are made of polarising materials, which display light based on how the liquid crystals are manipulated electronically. The LED transparent screens have three pixels – red, blue, and green. And these three pixels account for the screen’s colour quality.

Meanwhile, an LCD screen is made either with LED backlight or the traditional CCFL. An LCD screen is made of liquid crystals, which could render either a full-colour or monochrome display. Also, it comes with a light diffuser to spread the light evenly on the scream for colour uniformity.


Screens with LED are touted as more energy-efficient than their CCFL counterparts. It’s also thinner and renders better graphics and colour quality.


LCD and LED transparent screens might be what you need to enhance your TV viewing at home with family and friends. Now that you know the differences between these two types, you’ll be able to decide which TV to buy to ensure your needs are met.
