LED and OLED are two display technologies used in lighting, displays, and various electronics. Are you in the market for a device? Then you need to know about the performance, efficiency and cost of LEDs and OLEDs to choose right.
What is LED and OLED displays?
LED backlit displays are a kind of backlit liquid crystal display technology product. They employ light-emitting diodes to illuminate the liquid crystal layers surrounding that filter and let light images through. LED displays are preferred for their brightness, long service life, and low power consumption used in televisions, monitors, and billboards.
Compared to LCDs, OLEDs (Organic Light Emitting Diodes) do not need a backlight. The individual pixels in an OLED panel is itself a point of light. Each pixel manipulates light individually in the panel to produce images. OLED TVs have a high contrast ratio, true blacks and best angles of view due to the independent control of every pixel.
Key Differences Between LED and OLED Displays
Picture Quality
OLED displays provide sharp and pristine image quality with realistic colours, genuine blacks and infinite contrast ratio. LED displays are capable of both high brightness, and fairly decent color quality, but struggle with achieving perfect blacks due to their backlighting.
Energy Consumption
OLEDs are more power-efficient, especially when displaying darker content, as their pixel is self-emissive and can turn off entirely. LEDs, which have a constant light source, use more energy in general.
Lifespan
The inorganic constituents of LED displays give them a longer lifespan than OLEDs. In terms of limitations, OLED displays are superior but known to burn in and degrade in the long run, especially when displaying static content.
Price
LED displays are typically more affordable due to mature manufacturing processes and lower production costs. OLED technology, being more complex, comes at a premium price, often positioning it as a luxury option for consumers.
Advantages and Disadvantages of LED Displays
Advantages
- LED displays are characterized by low energy usage, less than that of the LCD technology, thus making them green products.
- They provide superior quality light and image quality and are again ideal for use in advertising, events, and gaming zones.
- They are long-lasting compared to other display technologies.
- LEDs provide wide viewing angles and seamless connectivity, ensuring consistent image quality from almost any perspective
Disadvantages
- They tend to be costlier upfront due to advanced manufacturing techniques and the use of rare materials.
- Brightness levels, while beneficial, may contribute to eye strain and light pollution, particularly for prolonged usage or poorly regulated installations.
- In large-scale setups, maintenance costs can rise, especially if individual LEDs need replacement or adjustments for outdoor usage.
- Additionally, certain LED displays may experience flickering, which can exacerbate discomfort for sensitive viewers
Advantages and Disadvantages of OLED Displays
Advantages
- OLED displays provide the most accurate color and are excellent in contrast, real blacks and bright colors that make viewing visually rich.
- They are thin, light, and can easily be shaped for use with preference in smart mobile phones, television sets, and wearable technology devices.
- OLED screens have faster response time while providing greater viewing angles than LED – an incredibly clear image from any angle.
- These features make OLEDs to be the most preferred in professional imaging, high-performance and multimedia applications.
- They are also more efficient when displaying darker picture content because only individual pixels are lighted.
Disadvantages
- Their major demerit is that burn-in and image retention is possible, thus images that are displayed on the screen can leave a permanent mark.
- The manufacturing process is complex, leading to higher costs compared to LED displays.
- Additionally, OLEDs have a shorter lifespan, particularly for blue pixels, which degrade faster over time. This makes them less suited for continuous heavy use or environments requiring high durability
Best applications for LED and OLED displays
LED and OLED displays are each well-suited for specific scenarios, depending on factors like image quality, brightness, and longevity. Here’s a breakdown of where each excels:
Gaming
OLED displays dominate for gamers seeking top-tier visuals. Their ability to achieve true blacks and nearly infinite contrast ratios ensures immersive gaming, especially in dark environments. OLED’s faster response time also makes it ideal for use in high-end gaming since it minimizes motion blur. However, burn-in risks from static UI elements may concern long-term users.
LED displays are slightly cheaper for occasional or professional game players. They are available with higher brightness, as they are useful in brightly lit rooms and are not susceptible to burn-in. With advancements like MiniLED, LEDs now provide improved contrast and local dimming capabilities, narrowing the gap with OLED
Home theater
For home theater setups, OLED is often the go-to choice. Its pixel-level light control provides a cinematic experience with deep blacks and vibrant colors. Movies with HDR content shine on OLED, offering unparalleled detail and color accuracy. If price isn’t a barrier, OLED is hard to beat in this category
LED displays are better for rooms with ample natural light, thanks to their higher peak brightness. MiniLED TVs, in particular, deliver impressive HDR performance and are more affordable than OLED, making them suitable for budget-conscious buyers
Outdoor advertising
LED displays lead the pack for outdoor advertising due to their robustness and brightness. High-powered LEDs maintain visibility even in direct sunlight, and their durable construction withstands varying weather conditions. OLED, with its susceptibility to burn-in and lower brightness, is less suitable for this application
Professional editing
For professional editing tasks like photo or video editing, OLED displays are preferred. Their superior color accuracy and wide viewing angles make them indispensable for precise work. Creators working with HDR content benefit significantly from OLED’s capability to reproduce subtle color gradations.
Future trends in LED and OLED display technologies
The next few years will see exciting advancements in LED and OLED technologies with significant market implications.
- MiniLED and MicroLED breakthroughs
MiniLED displays are becoming mainstream, offering better local dimming and contrast at a fraction of OLED’s cost. MicroLED, an emerging technology, aims to combine OLED’s pixel-level lighting with LED’s brightness and durability. By 2025, we may see wider adoption of MicroLED in premium TVs and commercial displays
- Improvements in OLED longevity and efficiency
Manufacturers are addressing OLED’s burn-in and brightness limitations. Technologies like RGBW (red, green, blue, and white subpixels) are improving OLED efficiency, and the introduction of tandem OLED structures is extending panel lifespan. These enhancements will make OLED more appealing for long-term use in various applications
- Flexible and transparent displays
OLED’s flexibility enables curved, foldable, and even rollable displays, which are increasingly featured in high-end devices. Transparent OLED screens could redefine advertising and retail displays, allowing content to float seamlessly on glass
- AI-driven optimizations
LED and OLED displays are also implementing AI for real-time image adjustments to boost upscaling and HDR capability. The integration of artificial intelligence in LED and OLED displays is changing how visuals are experienced as more high-end options are made available at a lower cost.
For instance, LG’s 2025 QNED evo series features the new AI processing technology that were, before now, only found in OLEDs. With AI, these TVs optimize color, remove noise, and optimize image brightness based on the scene being shown.
LG QNED evo OLED TV line comes with LG’s α8 AI Processor to enhance upscaling capabilities of images, virtual surround sound effect and dynamic tone mapping for optimum clear image and audio enhancement.
Conclusion
The decision between LED and OLED rests on determining what is most important for you. Are you a gamer a professional video editor, or are you using your laptop outside? When you’ve identified your needs, the knowledge you’ve just gained makes choosing easy.
