The TV has come a long way today. What started off as black and white screen has now developed into a wide range of technologies. What’s more, the tech that powers your TV is constantly developing each day, so there’s something new that pops up quite frequently. Amongst all this, you might have heard about LED vs LCD TV frequently. So, what are these really?
In this blog, we will cover all these aspects and much more. This might help you purchase your next TV, while also making you an expert in this field. Keep reading!
You may have heard about a wide range of displays, such as HD, 3D, smart, 4K, UHD and lots more. However, the LCD and LED TVs are still quite famous and well-known by the common folks. Before you start thinking about the difference between LCD and LED TV, or the LCD and LED TV difference, it is important that we cover their main definitions first.
The full form of LCD is Liquid Crystal Display. This liquid crystal has both solid and liquid properties. The LCD monitors or screens have backlights behind the main screen. This enables them to emit the white light. These screens have two different layers of polarised glass through which liquid crystals can either block or pass the light.
However, LED screens have the same form of technology too. That is why, it is quite commonly said that all LED screens are LCD screens, but you cannot say that all LCD screens are LED screens.
The term LED stands for Light Emitting Diodes. One of the differences that separates it from LCD TVs is that LCD TVs use fluorescent lights, while LEDs make use of diodes. These diodes are extremely small lights, which in turn helps to save space.
In addition, the placement of these lights can also differ. In the case of an LED, the lights are placed behind the screen or around the edges. This LCD and LED TV difference can also lead to changes in the physical shape of the screens. For example, LEDs generally tend to be comparatively thinner than LCDs.
If you are strictly going by comparison of picture quality, then an LED TV is much better than a regular LCD screen. The main reason for this is that LED TVs have RGB colour wheels installed within them. Hence, the image output is significantly sharper and realistic as well. Furthermore, the dimming properties exhibited by the diodes means that they are able to provide better colours by blocking excessive lights that may hamper your viewing experience.
Another benefit that goes for LEDs is that they also last longer than LCD screens. An LED will go on for 100,000 hours, whereas LCDs suffer from a shorter lifespan of about 75,000 hours. To tip the scales further in favour of LEDs, you should know that they consume lesser power as well. Therefore, if you are still thinking which is better between LED or LCD TV, then you know the answer by now.
Do keep in mind that while noting the LCD and LED TV difference, always choose full array LED screens. These are almost always much more superior to the LCD variants. However, if you do come across an edge lit LED, then you might as well go for an LCD screen, since they are not as good.
Edge lit LEDs are usually thinner than the regular screens. Also, they are quite cheap to manufacture, and that is what makes them lighter on the pocket too.
Whether you go for an LED, or an LCD TV is totally on you, and depends on number of factors too. Despite the clear superiority of LEDs, you might like to go for an LCD TV simply because the offer is better. However, what about your smart TV experience?
Smart TVs are great, yes. They come with a host of features and multiple state-of-the-art features. But they can be expensive too.

The main difference between an LED and LCD monitor comes from the display technology used to create the picture displayed.
First, an important thing to understand is that the LED (Light Emitting Diode) monitor is an improvised version of the LCD (Liquid Crystal Display). This is why all LED monitor is LCD in nature, but not all LCDs are LED monitors.
LCD technology revolutionized monitors by using cold cathode fluorescent lamps for backlighting to create the picture displayed on the screen. A cold cathode fluorescent lamp (CCFL) is a tiny fluorescent bulb. In the context of this article, LCDs refer to this traditional type of CCFL LCD TVs.
LED monitors took the old technology a step further by replacing the fluorescent bulbs with LED backlight technology. And OLED (organic light-emitting diode) technology improves it even further by eliminating the need for backlighting. So with LCD vs LED, LCD is essentially the old technology.
Early LED monitors had the LED lights placed on the edge of the monitor, called LED edge lighting. However, monitors have changed since then.
Now, LED monitors are direct-view LEDs. Direct view LEDs go a step further and replace the entire screen with an array of LEDs.
This turns a single monitor into a modular assortment of countless light-emitting diodes. Additionally, this expands how big the monitor can be without blowing up the cost exponentially.
The quality of direct-view LED screens is measured by pixel pitch. The pixel pitch is the distance between two adjacent LEDs on the display. The smaller the pixel pitch, the better the quality of the image.
To answer the question ‘which is better- LED or LCD TVs?’, we need to evaluate them on various factors that make a display better or worse.
Let us go through these factors one by one and understand which technology wins in each criterion:
Since LEDs replace fluorescent bulbs with light-emitting diodes, LED TVs are more energy-efficient than LCDs. A 32-inch LED TV screen consumes 10 watts less power than the same size LCD screen. The difference in power consumption increases as the size of the display increases.
Light-emitting diodes are considerably smaller than fluorescent lamps used in LCD monitors. Fluorescent lamps have a considerable thickness, but the thickness of diodes is next to none. Moreover, countless diodes are assembled in the same plane, so the thickness of the array isn’t increased no matter how many diodes are present.
Therefore, an LED panel is thinner than an LCD panel. On average, an LED screen can be one-third the thickness of an LCD screen of the same size.
Edge-lit LEDs have a slight drawback in viewing angle compared to LCDs, because of the position of the light source. However, direct-view LEDs offer a better angle for viewing than LCDs as the light source is evenly spread on the screen.
This is the time it takes to shift from one colour to another. Response times are generally measured in milliseconds (ms). The shorter the time to respond, the better the quality of the images produced.
When it comes to LCD vs LED, typically, LED TVs have shorter (better) response times than LCD screens.
Since LED displays use full-array LED backlighting rather than one big backlight, LED TVs offer significantly better contrast than LCDs. LCD backlighting technology only shows white and black, but LED backlighting can emit the entire RGB spectrum, thereby providing a deeper RGB contrast.
If you wonder which display will last longer, this debate is also won by LED displays. LED televisions have a longer lifespan of 100,000 hours on average, compared to 50,000 hours provided by LCD televisions.
An LED display provides the option to dim the backlight, along with other eye comfort features. Not only that, it provides a wider viewing angle without harming image quality. Therefore, an LED display is far better for your eyes than an LCD.
In an LED display, a lot of smaller diodes are used and if a diode is damaged, it can be replaced. In an LCD, you will need to replace the entire bulb in case of damage. Therefore, an LED display is easier and cheaper to maintain than an LCD.
Since LEDs are a better and newer technology, the price of an LED display is higher than an LCD. However, this is only when we are considering the purchase cost.
When you consider factors such as lifespan and maintenance, an LED display turns out to be cheaper than an LCD one in the long run.
The picture quality of an LED display is far better than an LCD. Due to modular light-emitting diodes, an LED screen produces better control over the contrast, rendering a clear picture. Also, LED provides RGB contrast, which can show truer blacks and truer whites.
Not to forget, they provide a shorter response time as well. Both of these factors result in LED displays having a better picture quality compared to LCD displays.
Since LED displays are considerably thinner than LCDs, they weigh considerably less. On average, an LED screen weighs about half of an LCD screen of the same size.
As you might have noticed by now, LED wins the battle with LCD without any doubt. This is because LED displays have an advantage in all the factors that matter when considering a purchase, except price.
Even when you consider the price, you will find that while LED technology is costlier, it provides better value for money in the long run. This is because of the longer lifespan and easier maintenance of LED screens.
Therefore, if you are considering buying a display for yourself, you should go for an LED display without second thoughts.
LCD vs LED? The LED is often regarded as a third-generation display. It meets the demands and preferences of the new generation very much.
They are more attractive too. With the increasing shortage of space in new residential complexes, what better solution than an ultra-thin LED display giving a cinematic experience in the comfort of your home.
