LED vs. OLED Screen: Which Display Technology Is Better?

/ By

The era of OLED screens has come with a bang. However, traditional LED display technology has not backed down! To help you make a better choice in this LED vs OLED screen battle, this article provides valuable insights into their key differences and similarities, benefits and limitations, and application areas.

What is LED Technology

The core of the  LED display technology is the tiny light-emitting diodes or semiconductors that serve as tiny pixels. When you pass an electric current through them, they emit light in a phenomenon known as electroluminescence.  

The light emitted by LEDs acts as a backlight for LCD(Liquid Crystal Display) screens which are capable of displaying images in millions of colors. 

What Is OLED Technology?

OLED is an acronym for new display technology and stands for organic light-emitting diodes. When you pass electric power on individual pixels or organic diodes in OLED displays, they emit their light for ready image display. So, unlike traditional LEDs, they do not require LCD panels.

LED vs OLED: Differences & Similarities | Benefits & Drawbacks 

Key Differences

Below are the major differences between LEDs and OLEDs that you must be aware of when choosing between these two rival technologies.

  • Initial Cost: LEDs are generally cheaper compared to OLEDs. This is because of their simple manufacturing process.
  • Sizes and Models: You will easily find LED display solutions in a wider range of sizes and models than OLEDs which are still new in the market.
  • Display Screen Thickness & Design Flexibility: OLED display screens are thinner in design. This is because they do not require image LCD panels. However, if you want to achieve various display sizes, LEDs have module designs that make them more flexible than OLEDs
  • Light and Image Generation: LED technology is used for backlighting and requires a special LCD screen to modulate the light for image generation. This is because you cannot control individual pixels. However, for OLED displays, individual pixels generate their own light and image colors with no need for LCD panels.
  • Color Display & Contrast Ratio: OLED allows for absolute color control allowing you to have a black screen, white screen, or any specific color illumination. So, it offers a better color display and contrast ratio than you would achieve with LEDs.
  • Design Flexibility: You will find LED solutions in a wide range of flexible designs to suit your application needs.
  • Fast Response To Moving Images. OLED display screens respond much faster to moving images than LEDs.  This is because of their high refresh rate.
  • Power Consumption: OLEDs are more energy-efficient than LEDs because they do not require LCDs to facilitate image display.
  • Lifespan: Traditional LEDs generally have a longer lifespan than OLEDs whose organic compounds deteriorate with time.
  • Black Display: OLED displays like OLED TVs will provide you with a “true black” display compared to LEDs because they produce their light and image. So, when the pixels are switched off, you get a true black display.

Similarities Between LED and OLED

Apart from their differences, here are some of the similarities the two technologies share that you must be aware of:

  • Light-Emitting Diodes: Both LED and OLED have diodes that emit light through electroluminescence.
  • Efficiency In Power Consumption: Both LED and OLED technologies guarantee high energy efficiency. Unlike traditional light solutions, these technologies consume less power while emitting more light.
  • Safety: The materials used in LED and OLED lights are less harmful to the environment, ensuring safety. For instance, unlike traditional fluorescent lights, both LED and OLED lights do not contain mercury.
  • Versatility: Manufacturers use both technologies to produce various types of light fixtures. The compact nature of their light-emitting diodes makes them suitable for the manufacture of small display screens like those of smartphones, smartwatches, and other mobile devices.
  • Excellent Color | Quality Image Display: LED and OLED technologies provide excellent displays of colors, making them ideal for high-quality lighting and image displays.
  • Excellent Viewing Angles: Users can comfortably view displays on both LED and OLED screens at different viewing angles. Modern LED and OLED display screens have special anti-glare films for enhanced viewing comfort.
  • Durability: Both LED and OLED are durable and so will serve you much longer than traditional fluorescent or incandescent lights. 

Comparing the Advantages and Disadvantages of LEDs vs OLEDs

 

Advantages and Disadvantages of LEDs

Advantages And BenefitsDisadvantages/Limitations/Drawbacks
  • Less expensive compared to OLEDs which makes it a perfect choice if your project has a limited budget.
  • High-energy efficient making them suitable for your LED display lighting applications such as outdoor security lighting, photography lighting, or for your events dynamic lighting.
  • They are available in different sizes and designs, which makes their implementation faster. Therefore, you will easily find the right LED display screen size for your Indoor LED advertising, Out-of-home Advertising, Events Advertising, and Promotional displays at shopping stores, cafes, restaurants, and bars.
  • Provides high brightness for desired outdoor visibility even in sunny locations. This makes them suitable for outdoor displays such as digital billboards.
  • Available in flexible modular designs, which allow for scaling to suit your project needs. You can also get customized flexible LED display designs to suit your installation requirements.
  • It provides an excellent display of colors, which makes it an ideal display technology for learning institutions, the advertising industry,  and sports displays such as  LED scoreboards.
  • Simplicity in design, a long lifespan,  and low maintenance costs make it suitable for outdoor installations such as traffic light signals, business signs, etc.
  • Fast response to changing images, especially those with NT( twisted nematic) panels. This makes it suitable for gaming applications.
  • Wide viewing angles of up to 170° especially those enhanced with in-plane switching, Vertical Alignment, and anti-reflective coating.  This makes them ideal for your live events or concert displays as they guarantee consistent viewing from different areas.
  • Side view distortion as you move closer to the sides of your screen because it relies on backlighting
  • Bulky Designs because they require LCD screens for display
  • Less Angle of Viewing when you compare it with OLEDs 
  • Its response rate or refresh rate  is not as high as that of OLEDs
  • Limitations on contrast and color accuracy if you compare with OLEDs because it relies on backlighting.

 

Advantages and Disadvantages of OLEDs
