LED vs LCD Technology

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.

Direct View LED (aka LED Display)

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.

Is LED or LCD Better?

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:

Energy Efficient

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.

Size

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.

Viewing Angle

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.

Response Time

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.

Contrast

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.

Which Lasts Longer, LCD or LED?

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.

Is LED or LCD Better for the Eyes?

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.

Maintenance

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.

Cost

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.

Which Has Better Picture Quality – LED or LCD?

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.

Which is Heavier, LCD or LED?

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.

Why LED is Better Than LCD

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.

Conclusion

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.

LED screens are the first choice among the public today, across generations. All are opting to switch to LED from LCD to make their lives more enjoyable and better.

Frequently Asked Questions

Sometimes the distance between good and great seems like hardly any distance at all — such as liquid crystal displays (LCDs) versus light-emitting diode (LED) displays. Both are suitable for retail window signage, campus wayfinding or large video walls. But LCD and LED have significant differences, and their specific benefits are worth understanding so you can choose the best displays for your business needs.

Defining LCD displays

LCD is the broader category; LED is a subset. In other words, all LED displays are LCDs, but not all LCDs are LED. LCDs are made up of hundreds of thousands — even millions — of individual pixels built from liquid crystals. Each pixel is capable of displaying a color when it receives an electrical charge. Like a mosaic, the displayed image is built from tiny elements that combine to form the overall picture.

But the liquid crystals don’t produce any light of their own, so in order for the image to be illuminated, the liquid crystals need to be backlit. LCDs are illuminated by cold cathode fluorescent lamps (CCFLs), evenly positioned behind the pixels so that, at least in theory, every part of the screen is evenly lit and at consistent brightness.

Refining the tech with LEDs

Up to a point, LED displays are much the same. An LED screen also uses liquid crystals to generate color — or pure black (no color), by not charging a specific pixel. So LED displays have the same need for backlighting. But rather than CCFL, tiny individual lights (light-emitting diodes) illuminate the liquid crystals.

The individual LEDs can be arranged one of two ways: full-array or edge-lit. For edge lighting, the LEDs are arranged around the edges of the back of the screen. Full-array, on the other hand, calls for many LEDs to be lined up evenly across the back of the screen, where they can be arranged into zones (usually called “dimming zones” or “local dimming”).

LED vs. LCD: Which is better?

Is LED just plain better than LCD? Well, for a while, LCD screens represented the cutting edge of digital signage. But now, about the only meaningful advantage of LCD over LED is price point. As LCD is becoming outdated, it tends to be less of an upfront investment. In every other respect, though, LED displays have the advantage.

No matter the arrangement of the backlighting, LED has a greater nit value than LCD, which means it’s brighter (“nit” comes from the Latin “nitere,” meaning “to shine”). The average nit value for LCDs is between 500 and 700 nits, while LEDs are typically between 1,200 and 2,400 nits. With greater brightness comes greater contrast, and all-day visibility on outdoor displays.

Despite the energy output, higher brightness doesn’t necessarily mean a shorter lifespan. In fact, LED displays have an average lifespan of 10 years — double the average five-year lifespan of LCDs. Factoring longevity into the cost of your signage, LED’s longer lifespan can make it cheaper than LCD in the long run.

Even with edge lighting, LED produces more vividly lifelike images than CCFL-backlit LCDs — and with sleeker hardware, thanks to their minimalist design. And while LCD bezels have drastically reduced over time, they’re still greater than zero. LED has no bezels at all.

Full-array backlighting requires a little more depth to the screen, but with discrete dimming zones, LEDs can be illuminated far more precisely — which, in turn, means more accurate and engaging visuals.

Next generation: microLED

LED isn’t the first technology to realize miniaturization is the way forward. Even as screens get bigger, the next big step is made of smaller parts: microLEDs.

Up to 40 times smaller than regular LEDs, microLEDs allow backlighting to be even more precisely targeted, with many times more diodes. This, in turn, delivers a more accurate picture, with greater contrast and highly focused areas of brightness. Samsung’s The Wall is a spectacular example of what microLED is capable of.

Whether you need your digital signage to entertain, inform or simply impress, understanding the differences between LCD and LED will allow you to make a better-informed decision.
