What’s the Difference between LED and LCD?

There are a few critical factors you need to consider when you’re deciding between LED and LCD displays, particularly, viewing distance, the physical location of the screen, the environment in which it’s being showed and the content that’s being displayed.

The table below helps to understand the key differences between LED and LCD screens. Overall, LCD is generally preferred because of it’s picture quality, indoor preference, cost effectiveness and image reliability.

 

  LED

  LCD

Ease of installation   Bulky, heavy and slightly more complex than LCD   Quick and easy to install
Flexibility of design   Significant design freedom with size   Various sizes and formats
Quality of image
  • Pixel pitches range from 0.9 – 20mm
  • Deep saturated colors with a wide color gamut
  • No screen bezel or gap
  • Pixel pitches between 0.5 – 0.6mm
  • Quality brightness and contrast available
  • Full HD 4K and more
Reliability
  • No image retention
  • 100,000 hours to half brightness
  • 24/7 performance
  • Image retention is a common issue
  • Ranges from 30,000 – 50,000 + hours
Maintenance requirements
  • Automatic calibration without interrupting the image, reflecting the colors and brightness of other tiles in the display
  • Components are difficult to replace due to size
  • Image quality settings are pre-set and ready to go
  • Easier to replace new for old

 

What’s Better – LED or LCD Screen?

LED Screen Displays

LED screens have become a mainstay in the large event category with their optimal picture resolution and capability to emit high light levels. Through use of Light Emitting Diodes (LED), these systems produce red, green and blue light. By combining and balancing these three primary colors, the user can produce virtually any color on the spectrum.

Event screens are typically built from multiple panels that are connected together. These can be customized and scaled to any shape or size, although the larger the screen setup to increased cost and labor required.

Benefits of LED Screens:

•  The brightest screen offerings
•  Weatherproof and suitable for outdoor use
•  Energy-efficient
•  Flexible design
•  Quick and easy setup
•  No projection needed

Cons of LED Screens:

•  LED screens can be heavy or large, meaning they require rigging systems.
•  Can be costly
•  Requires additional floor space area
•  Can only be viewed from a distance.

LCD Screen Displays

LCD screens are normally seen in smaller more consumer-driven displays, such as in-store retail environments, window displays and shopping centres. This screen option is ideal for digital applications where an affordable but high-quality display is needed. Additionally, with a wide range of connectivity options, these screens are versatile.

Benefits of LCD Screens:

•  More cost effective
•  Multiple levels of screen quality available
•  Lightweight, allowing quick and easy rigging
•  Versatile connectivity with standard connections being VGA, HDMI, composite component, DVI and S-video output
•  Adaptive levels of brightness available for all indoor applications

Cons of LCD Screens:

•  Larger screen sizes generally incur greater cost
