Choosing the right type of LED display can be challenging with the options available today. Two popular technologies, the Edge-lit LED Display and the Direct-lit LED Display, offer distinct advantages and drawbacks. In this article, we'll explore the differences between these technologies to help you make an informed decision for your next purchase.

Edge-lit vs Direct-lit LED Display

What is Edge-lit LED Display?

An Edge-lit LED Display is a type of LED television where the LEDs are positioned along the edges of the screen. This design allows for a thinner and lighter display, making it an attractive option for modern home decor and wall mounting.

Working Principle

Edge-lit LED displays use a light guide plate to distribute light from the LEDs along the edges evenly across the screen. This creates a uniform backlight that illuminates the entire display, allowing for vibrant images and energy efficiency.


  • Slim Design: The positioning of LEDs along the edges enables a sleek, ultra-thin profile, ideal for contemporary aesthetics.

  • Cost-Effective: Generally more affordable than direct-lit LED displays, making them accessible to a wider range of consumers.

  • Energy Efficient: Consumes less power, contributing to lower electricity bills and a smaller environmental footprint.


  • Brightness Uniformity: Edge-lit displays can sometimes suffer from uneven brightness, especially in larger screens or when displaying dark scenes.

  • Limited Local Dimming: Unlike direct-lit displays, edge-lit LEDs have fewer zones for local dimming, which can affect contrast and black levels.

What is Direct-lit LED Display?

A Direct-lit LED Display is a type of LED television where LEDs are placed directly behind the screen, covering the entire back panel. This design provides more consistent and uniform lighting, which enhances the overall picture quality and viewing experience.

Working Principle

Direct-lit LED displays use a full array of LEDs spread across the back of the screen. These LEDs illuminate the display directly from behind, ensuring that light is evenly distributed across the entire screen. This method allows for precise control over brightness and contrast, resulting in superior image quality.


  • Superior Picture Quality: The direct placement of LEDs provides more uniform brightness and color accuracy, making images appear more vibrant and lifelike.

  • Better Contrast and Black Levels: With more local dimming zones, direct-lit displays can turn off specific areas of the backlight, enhancing contrast and delivering deeper blacks.

  • Consistent Brightness: Ensures uniform brightness across the screen, avoiding issues like edge shadowing that can occur with edge-lit displays.


  • Bulkier Design: The need to accommodate LEDs behind the screen results in a thicker and heavier display, which might not be as aesthetically pleasing as edge-lit models.

  • Higher Cost: Typically more expensive due to the increased number of LEDs and more complex manufacturing process.

  • Potentially Higher Power Consumption: May consume more energy, impacting electricity usage and costs over time.

What's the Differences Between Edge-lit and Direct-lit LED Display

Now that we have a clear understanding of both Edge-lit and Direct-lit LED displays, let's dive into a detailed performance comparison. This will help you determine which type best suits your specific needs.

Picture Quality

Direct-lit LED displays provide superior picture quality with more uniform brightness and accurate colors. Edge-lit displays can suffer from uneven brightness, particularly at the edges, impacting overall image quality.

Brightness and Contrast Levels

Direct-lit displays provide better brightness and contrast levels due to advanced local dimming capabilities. Edge-lit displays, with fewer dimming zones, struggle to achieve the same level of contrast, resulting in less deep blacks.

Viewing Angles

Direct-lit displays often maintain better image quality from wider viewing angles. Edge-lit displays can show degradation in image quality and color accuracy when viewed from the sides.

Energy Efficiency

Edge-lit displays are typically more energy-efficient, consuming less power compared to direct-lit displays. This can lead to lower electricity bills and a smaller environmental footprint.

Durability and Lifespan

Both types of displays are generally durable, but direct-lit displays might have a slight edge in long-term performance and reliability due to the even distribution of LEDs across the back panel, reducing the risk of individual LED failures impacting overall display quality.

Cost Considerations

When considering the initial purchase cost, edge-lit LED displays are generally more affordable, making them accessible to a broader audience. Their slimmer design and less complex manufacturing process contribute to their lower price point. Direct-lit LED displays, on the other hand, tend to be more expensive due to the higher number of LEDs and more advanced technology used to enhance picture quality and performance.

While direct-lit displays have a higher upfront cost, they can offer better long-term value through superior picture quality and durability. Additionally, the enhanced performance in brightness and contrast can be more satisfying over time. Edge-lit displays, though cheaper initially, are more energy-efficient, potentially leading to savings on electricity bills. This makes them a cost-effective choice for those prioritizing lower ongoing expenses.

Full-Array LED Display

A Full-Array LED Display features LEDs evenly distributed across the entire back panel of the screen, similar to direct-lit displays but with more precise control. This setup allows for advanced local dimming, where specific zones of LEDs can be dimmed or brightened independently, resulting in superior contrast and deep blacks.

Full-array LED displays offer exceptional picture quality with uniform brightness and accurate color reproduction, making them ideal for home theaters and professional settings. They provide a balanced blend of the benefits of direct-lit and edge-lit displays, offering better performance without compromising on thickness and energy efficiency, although they are generally at a higher price point.


In summary, edge-lit LED displays are cost-effective and energy-efficient with a sleek design but may suffer from uneven brightness. Direct-lit LED displays offer superior picture quality, better contrast, and viewing angles, though at a higher cost and bulkier design. Full-array LED displays provide the best of both worlds with advanced local dimming and excellent performance. Choose edge-lit for affordability, direct-lit for premium quality, and full-array for optimal performance.
