OLED vs LED SCREEN: Which Display Technology Is Better? 

The OLED vs. LED display debate is evergreen, owing to the innovative developments in both technologies and their range of applications. From definition to benefits, strengths, and use cases of each display technology, this article will give you all you need to know to make an informed decision between OLED and LED screens.

Definitions

What Is OLED Display Technology?

OLED is a modern display technology that manufacturers use to create electronic gadgets, including smartwatches, curved screens, smartphones, smart home television screens, personal computers, and other wearable devices. 

They do not consist of traditional light-emitting diodes or liquid crystals. Instead, they comprise light-emitting organic compounds that beam automatically when an individual applies electric current.

What Is LED Display Technology?

An LED display is a technology built on the illuminating prowess of light-emitting diodes (LEDs). When connected to a power source, LEDs give off light. And depending on the arrangement or architecture, you can get up to 16 million colors from LEDs to display various forms of content on screens. 

LED display technology arranges these semiconductors in a matrix or grid, and they can independently turn on and off in a precise pattern to create high-quality images or video. LED screens have vast applications, including digital signage, billboards, scoreboards, and other displays requiring high brightness, contrast, and visibility in indoor and outdoor environments.

Features of OLED Display Technology?

OLEDs are popular for the right reasons, fast refresh rates, foldability, wide viewing angles, vibrant color displays, etc. If you are stuck on the OLED vs. LED display technology debate, here is a run-through of 12 features of OLEDs:

• High-quality Color Displays: Due to the lack of backlighting in OLED display technologies, OLED displays emit their light while producing bright, vivid colors with high contrast ratios and deep blacks, giving viewers a more realistic and fascinating viewing experience.
• Fast Response Time: Another bestselling feature of OLED display technology is its fast response time—the speed it requires to change from one display to another or its ability to switch from one particular color to another very quickly. This feature makes OLEDs ideal for fast-paced gaming and video playback displays.
• Thin and Flexible: Manufacturers can get extremely creative with OLED displays because they are thin and can make flexible screens. Their size and flexibility allow designers to create new and unique product designs. 

 

• Energy Efficiency: OLEDs are more energy-efficient than traditional display technologies since they do not require a backlight to function, and each pixel emits light. This feature allows them to use less power, as only the necessary pixels give off light rather than the entire screen.
• Wide Viewing Angles: When you are on the market or shopping for a new display technology, a wide viewing angle is one of the features to consider. OLED displays have wider viewing angles than traditional LED displays. Therefore, the image, video, graphics, or display text quality remains the same from any angle.
• High Contrast Ratio: High contrast ratios are another great feature of OLED displays. The contrast ratio is the level of black and white your screen has, determining how clear your display image, graphic, text, or video will be. OLEDs simultaneously display deep blacks and bright whites, resulting in a more dynamic image.
• Uniform Lighting: A common issue in traditional LED display technologies is backlight bleeding—where light leaks around various parts of a screen, leading to an uneven spread of light across such screens. On the other hand, OLED displays do not have the backlight bleeding issue; they have uniform lighting across the entire screen.
• Wide Color Gamut: Another important feature of OLED display technology is the range of colors a screen can reproduce. Displays with wider color gamuts can reproduce multiple colors, producing more vibrant and accurate texts, graphics, videos, and images.

OLEDs have a wider color gamut since they use organic compounds to produce light-emitting pixels. These organic materials emit light at much larger wavelengths, allowing OLED screens to produce multiple colors simultaneously.

• High Refresh Rates: OLED displays can refresh more rapidly per second than other display technologies, resulting in smoother motion and reducing motion blur in fast display scenes. In addition, OLEDs have lower input lag levels, which is the delay between when you make an input and when the screen displays your action. 

OLED displays have a refresh rate between 60 Hz and 120 Hz; therefore, it updates the image, text, graphic, or video on the screen up to 120 times per second. Hence, OLED users have a smoother, more responsive experience.

• Improved Color Accuracy: OLED display technology has a more accurate color reproduction, meaning that the image, graphic, and video colors on the screen are closer to the source material.

• Long Lifespan: OLED displays can maintain their brightness and color accuracy for a long since they do not rely on a backlight, which degrades in the long run and causes the display to dim or lose color. 
• Low Blue Light Emission: Blue light is a high-energy visible (HEV) light that can harm our eyes from long exposure to screens with high blue light levels. Studies show that exposure to blue light can disrupt sleep patterns, cause eye strain, and potentially contribute to long-term vision problems. 

OLED displays have a lower blue light emission since they emit light directly from each pixel. Also, many manufacturers incorporate features that allow users to adjust the screen’s color temperature, further reducing blue light emissions and providing a better viewing experience.

Features of LED Display Technology?

To give you a clear insight into what makes LED displays one of the best technologies on the market, here are some main features of LEDs:

• High Brightness: LED screens offer high brightness even higher than OLEDs, ideal for indoor and outdoor use. Whether you need display technology for small or large indoor or outdoor gatherings, LED screens have brightness levels that will help your audience see without straining their eyes.

• Energy Efficient: LED displays do not consume much power like other display technologies, like LCDs making them more energy-efficient and cost-effective in the long run. Energy efficiency protects the environment and prevents you from spending too much on the light bill.

LEDs convert electricity into light more than traditional display technologies, which often rely on complex light-generating mechanisms.

In fact, LED screens only turn on when there is a photo or video display. Unlike traditional display technologies that use a constant power supply for the backlight to keep the screen going, LED displays can adjust their power consumption based on the displayed content.

This dynamic power management system increases the energy efficiency of LED displays, reduces their environmental impact, and lowers energy costs.

• Wide Viewing Angle: Like OLEDs, viewers can see images, text, and video clearly from almost where they are sitting in the room or congregation. Other display technologies with limited viewing angles do not share this luxury and can cause eye strain and other display artifacts when viewing them from other angles.

LED displays have wide viewing distances using In-Plane Switching (IPS) or Vertical Alignment (VA). This technology aligns liquid crystal molecules on the screen to ensure consistent picture quality and color reproduction over various viewing angles.

In addition to IPS and VA technologies, LED displays often use other techniques to improve viewing angles, such as advanced anti-reflective coatings and polarizers, reduce glare and improve contrast, making the screen easier to see in bright environments or outdoors.

This feature makes them ideal for a variety of applications such as digital signage, large rallies, street advertising, other promotional displays, and large format video walls. It also means many viewers can enjoy it without straining their eyes and neck.

 

• High Color Gamut: One of the best features of LED screens is their wide color gamut, the range of colors the screen can display. If you are purchasing a LED screen or currently have one, You’ll love the fact that it is common for delivering vibrant, accurate colors that make bold statements.

With green, red, and blue as their basic colors, LEDs can create up to 16 million rich colors for better display. In addition, manufacturers use advanced technologies such as quantum dots or phosphor coatings to expand the color gamut, resulting in even more vivid and accurate colors.

You will find the wide color gamut most relevant when carrying out tasks like image editing or video creation. With an LED display, the colors you see are original and vibrant, allowing you to have the best possible end product.

• High Resolution: If you’re in the market for a new display technology, you know well to consider an LED display with high-resolution features. When it comes to resolution, LED screens are capable of producing extremely clear images with a pixel density per inch. 

Manufacturers achieve this by creating extremely small and densely packed LEDs, allowing for high pixel densities, which means more pixels per inch and greater detail in images, texts, graphics, and videos.

• Long Lifespan: LEDs are solid-state devices with no moving parts to wear out in the next few years. This makes them much more durable and long-lasting than other types of displays like LCDs. In addition, LED screens do not suffer from the same type of burn-in as other screens, which can also reduce their lifespan.

Although the exact lifetime of an LED screen depends on many factors, including the quality of structural components, frequency of use, and installation environment. 

• Flexibility: LED screens are not only unique for their high resolution and long lifespan but also offer a high degree of flexibility in terms of design and mounting options.

Many consumers prefer LED screens for their varied applications, from commercial LED displays to rental LED displays in public spaces. You can install it anywhere in residential buildings, walls, and ceilings.

• Durability: Unlike other screens, such as LCD screens, LED screens do not use mechanical parts to create images, videos, graphics, and text. Instead, they consist of thousands of tiny LEDs producing light when you apply an electric current.

This feature enables them to be strong and possesses components that will not wear out over time; therefore, they resist damage from shock and other external factors. This makes them ideal for applications where the screen is subject to rough handling or needs far destination delivery frequently, e.g., trade fairs and events.

In addition, LED screens are suitable for operation in various temperatures and environments. They can operate in extreme temperatures from -40°C to 85°C without compromising performance or lifespan. This makes them useful in various environments, including outdoors, without the need to protect them from the elements.

• Scalability: The scalability of LED screens is one of their main advantages due to their modular design. The primary LED display architecture consists of numerous units of LED modules with room for more depending on the scale of the screen.

One can easily add these modules or remove them to customize the size and shape of the screen to suit your needs, making it easy to create screens of any size and configuration. This modular design also makes repairing or replacing individual modules easier in case of damage or malfunction.

This scalability is particularly useful in large-scale installations such as digital billboards and video walls, where the display’s size and configuration are needed depending on the viewing distance and available space. In these applications, LED displays can create large, high-resolution displays capable of displaying complex images and video content.

Comparison Between OLED and LED Display Technologies

Let’s take a closer look at how these two technologies differ from each other based on various parameters:

1. Picture Quality

It’s common knowledge among picture-quality enthusiasts that OLED is a few steps ahead of LEDs. This is because, unlike LED displays, OLED displays can produce fine black, bright white, and an infinite contrast ratio.

In contrast, LED screens use light-emitting diodes to illuminate the entire screen, which means that even when the display content is dark, some light will still emit. This can result in a washed-out look in dark scenes.

2. Power Consumption 

If you are comparing power consumption rates, OLED displays are more power-efficient than LED displays. This is because OLED displays only use power to light up the pixels, while LED displays use a backlight to illuminate the entire screen.

In an OLED display, each pixel emits light independently, so when your screen displays black, the light powering that particular pixel is off and not using any power. On the other hand, LED displays require a backlight to be on at all times, whether the screen displays dark or bright images, videos, or texts. 

This means that LED displays will consume more power regardless of the display content. However, the power consumption varies depending on the specific models of OLED and LED displays. Since other factors, such as screen size, also affect power consumption, we can say there is no significant difference in consumption for both displays.

3. Lifespan and Durability 

While OLEDs have better viewing angles and higher picture quality, LED displays have longer lifespans and higher durability. They use a backlight separate from the pixels, so the pixels themselves are not subject to as much wear and tear as they are in an OLED display. This means LED displays can last longer before significant picture quality degradation occurs.

In addition, LED display technologies are more durable than OLED displays because they are less prone to burn-in. This is more common in OLED displays because each pixel emits its light, and some pixels may be subject to more wear and tear than others.

However, it’s worth noting that both OLED and LED displays can have long lifespans if you properly care for and use them within the specifications your manufacturer recommends. 

4. Cost 

OLED displays are a modern and more advanced technology with improved features that are constantly evolving and making them more expensive to manufacture. Plus, the production process and speed of OLED displays are lower than that of LED displays, which contributes to higher retail costs.

On the other hand, LED screens are cheaper than OLED displays because LEDs are an older technology than OLED. It has been in existence for a long time and has a larger production volume, resulting in lower production costs.

5. Which is better for business settings? 

The choice between OLED and LED displays will depend on what your company needs the display technology for and the space they are installing. An LED screen, for example, for productivity tasks or video conferencing is more economical for office applications because it is cheaper than OLED screens and still provides a high-quality image.

However, suppose your business needs to display high-quality image or video content, for example, in a marketing or advertising context. An OLED display may be a better choice due to its flexibility and excellent picture quality.

Even if you want to view the content for a long time, e.g., at the reception, on the menu, or in the hotel lobby, an LED display may be a better choice due to its long lifespan and durability.

6. Which One Is Best for Gaming? 

When it comes to gaming, both OLED and LED screens can offer a great experience, but there are other factors to consider that can make one option better. In terms of image quality, OLED displays are superior due to their ability to produce true black and infinite contrast ratios. 

OLED screens also have a faster response time than LEDs, allowing consumers to interact with fast-action content without worrying about motion blur or other screen artifacts.

But this issue will barely bother gamers because the content you are displaying is barely stagnant, it is always moving from one position to another, but still bear in mind if you intend to play games with lots of static graphics, you may experience this artifact over time.

Conversely, LED displays are more durable and long-lasting than OLED displays, making them a better choice for gamers who plan to use their screen for many years. Aside from their long lifetimes, LED screens are also less prone to burn-in. Hence they are a better choice for games with static user interfaces (UIs).

7. Which Display Technology Is Best for Events?

LED displays are best for large gatherings such as concerts, trade shows, sporting events, and big outdoor parties. You can use large LED screens to display top-quality graphics, texts, videos, or images to large audiences. Manufacturers produce LED screens using dedicated materials that make them resistant to severe weather conditions, making them the best option for outdoor events.

On the flip side, OLED displays are best for indoor events where the audience needs a high-quality graphic, video, or image display, such as art exhibitions, trade fairs, product launch parties, or conferences. They have excellent image quality, color accuracy, and contrast, thus their fit for displaying high-quality images and videos in a smaller environment.

8. iPhone Screen

LEDs are semiconductors with sizes that are generally too large for small screens such as smartphones and wearable devices. The need for smartphones in various use cases is widespread, and Apple is one of the leading manufacturers on the market, recording over 100 million iPhone users worldwide. 

While they are large for small screens, iPhone screens use LED for their backlights due to their high brightness levels, and the iPhone 8 series, down to iPhone 1, uses in-plane switching (IPS) LCD screens.

However, Apple is incorporating OLED screens for the iPhone X and later series, except for iPhone XR, which uses an LCD liquid retina screen, and iPhone 11, which also uses an LCD liquid retina HD display. Apple uses OLED screens for some of its later series devices due to the technology’s color accuracy, and high dynamic range (HDR) display. 

It is always a good idea to consider an iPhone screen type before settling on one that is best for you. Still, many factors aside from the screen contribute to the quality of smartphones. Any iPhone OLED screen series would be best if you prefer a high contrast level, less power consumption, and much faster response rates.

However, if you prefer a cheaper option with a longer lifespan, more color accuracy, resistance to strong weather, and lower burn-in rates place your bets on the iPhone XR, 11, and the 8 series.

9. Dirty Screen Effect 

The dirty screen effect is a motion artifact that makes one part of your display technology appear darker than other parts of your screen. This issue is common with LED displays since they use backlights to light up the entire screen, and the backlight bleeds and spreads across your screen, disturbing your display.

On the flip side, each pixel in an OLED screen can light itself up and go off when necessary. Even if OLEDs experience such motion artifacts, their deep black features can help hide the dirty screen effect from being completely visible. Therefore OLEDs are less prone to DSE than LED displays.

10. Screen Heat Comparison

OLED screens produce less heat because they do not need backlights to display images, videos, texts, or graphics. Each pixel lights up independently when it needs to display content. Therefore, pixels not in use can remain off, hence reducing screen heat and allowing your display technology to be cool.

On the other hand, LED displays produce more heat than OLEDs due to the presence of the backlight that illuminates their panel and evenly distributes this light across the screen. Since all pixels are up and running simultaneously, they tend to produce much heat and become hotter when you display content for longer periods.

11. Which Technology Is Better for Curved Displays? 

It is possible for designers to make foldable LED screens, but remember they are thick and rigid, and that structure makes them more difficult to bend and fold. But OLEDs are more flexible, allowing manufacturers to easily bend and fold them into various configurations. OLEDs are usually thinner and lighter than LED screens, manufacturers bend and fold them into various shapes easily without wrecking picture quality.

How Do OLED and LED Display Impact the User Experience of Smart Home Devices? 

While many technological evolutions are contributing to the development of the smart home industry, OLED and LED technologies play an important role. They change how we consume media, interact with our devices and perceive our surroundings, and sometimes influence purchasing decisions.

OLEDs and LEDs are almost everywhere in individual homes, from TVs to bulbs and other household appliances. While the two technologies share some similarities, there are significant differences and advantages each has to each other and to the other that affects the user experience.

OLED screens come from organic materials that emit light when you pass an electric current through them. This feature allows each pixel, not minding the pixel pitch, to come on and off for a more immersive viewing experience, making them ideal for smart home devices like televisions and personal computers. 

Also, OLED screens have wider viewing angles than traditional LED screens, so image quality remains the same from different angles. On the other hand, LED technology is more versatile and suitable for various smart home devices, such as light bulbs, light strips, and smart home hubs.

You can also change the color or brightness of the LED lights to create the perfect mood in your space. In addition to color change, LED display technology lasts longer than traditional incandescent bulbs, helping users can save money. Generally, OLED vs. LED makes smart homes more convenient and efficient.
