When it comes to choosing a monitor, two of the most common options are LED and LCD displays. While both technologies use the same basic principle of blocking light from a backlight to create an image, there are some key differences to consider. LCD stands for Liquid Crystal Display, and these monitors use liquid crystals to control the passage of light. On the other hand, LED, or Light Emitting Diode, monitors use light-emitting diodes for backlighting, resulting in improved colour accuracy and visual clarity.
| Characteristics | Values |
|---|---|
| Display technology | LED and LCD are types of display technology |
| Backlighting | LED uses backlight technology with light-emitting diodes; LCD uses cold cathode fluorescent lamps (CCFLs) |
| Image quality | LED provides sharper and higher-quality images than LCD |
| Lifespan | LED has a longer lifespan than LCD |
| Price | LCD is cheaper than LED |
| Brightness | LED has a greater nit value and is brighter than LCD |
| Contrast | LED offers better contrast ratios than LCD |
| Colour accuracy | LED has improved colour accuracy over LCD |
| Response time | LED has faster response times than LCD |
| Power consumption | LED is more energy-efficient and consumes less power than LCD |
| Environmental impact | LED is more environmentally friendly due to lower power consumption and longer lifespan |
What You'll Learn
LED monitors have a longer lifespan
The longer lifespan of LED monitors is due to their more durable backlighting technology. LED backlights typically last 50,000 to 100,000 hours, while CCFL backlights in traditional LCDs last around 30,000 to 60,000 hours. This means that LED monitors can save money in the long run, despite their higher initial cost.
In addition to their longer lifespan, LED monitors also offer improved picture quality, thinner design, faster response time, and more environmentally friendly construction.

LED monitors have better colour accuracy
LED monitors offer superior colour accuracy to LCD monitors. This is due to their wider colour gamut, which ensures less colour distortion and produces more realistic images. High-end LED monitors can display a larger percentage of the sRGB and Adobe RGB colour spaces.
Full-array LED monitors, in particular, offer superior picture quality with improved contrast ratios and deeper blacks compared to LCD displays. This is because full-array LED monitors have a wider colour gamut and can display images with higher brightness and contrast.
The improved colour accuracy of LED monitors is also due to their use of backlight dimming, which LCD monitors lack. This allows for optimal contrast and colour quality, as well as the ability to display truer blacks and improve image contrast.
In addition, LED monitors with IPS (In-Plane Switching) technology tend to offer wider viewing angles than traditional LCD monitors. This means colours and contrast remain more consistent when viewing the screen from different angles.

LED monitors are more energy-efficient
LED monitors have superior power management features and require less power to produce the same level of brightness as LCDs. This can result in lower power consumption and reduced electricity bills over time.
LED monitors also have a longer lifespan than LCD monitors. On average, LED backlights last 50,000 to 100,000 hours, while CCFL backlights in LCDs last around 30,000 to 60,000 hours. This means that LED monitors can be cheaper in the long run, despite their higher upfront cost.
The higher efficiency of LED monitors also makes them ideal for long-term use, especially if you're looking for a screen with lower electricity bills.

LED monitors are more expensive
The price gap between LED and LCD monitors has narrowed in recent years as LED technology has become more common. However, LCD monitors have been on the market for longer and have lower production costs, making them a more affordable option.

LCD monitors are better for eye strain
Additionally, LCD monitors offer consistent lighting with more uniform backlighting across the entire screen. This even illumination can help reduce eye strain, especially in dark rooms. Furthermore, LCD monitors often have more affordable price points, making them a cost-effective option for reducing eye strain.
To further reduce eye strain, look for features such as backlight flickering prevention, Low Blue Light (LBL) technology, and dynamic brightness adjustment based on ambient lighting. You can also adjust your monitor's brightness and colour settings, ensure proper lighting in your workspace, and follow the 20-20-20 rule—every 20 minutes, look at something 20 feet away for 20 seconds.

Frequently asked questions
LCD stands for Liquid Crystal Display, which uses liquid crystals to control light passage. LED stands for Light-Emitting Diode, which uses light-emitting diodes for backlighting. All LED monitors are a type of LCD monitor, but not all LCDs use LED backlighting.
LED monitors generally offer better picture quality, improved colour accuracy, and higher contrast ratios. They also tend to be thinner, more energy-efficient, and have a longer lifespan. However, LCD monitors are usually more affordable and may produce less blue light, potentially reducing eye strain.
LED monitors are typically better for gaming due to their higher contrast ratios, improved colour accuracy, and faster response times. However, LCD monitors can still provide a good gaming experience, especially if they have a high refresh rate.
