OLED vs LED: The Differences and Which one is Better


In the digital age where screens are a significant part of our daily lives, the display technology we choose can greatly impact our viewing experience. Whether it’s for gaming, design work, or simply binge-watching your favorite series, the quality of your monitor matters. This blog post will delve into the intricacies of OLED and LED monitors, shedding light on their differences and helping you make an informed decision.

Understanding Display Technology: A Brief History

Display technology has come a long way since the days of bulky Cathode Ray Tube (CRT) monitors. Liquid Crystal Display (LCD) monitors soon took over, offering a thinner, lighter, and more energy-efficient solution. The next evolution was the LED (Light Emitting Diodes) monitor, which is essentially an LCD monitor that uses LEDs for backlighting. The latest in this lineage is the OLED (Organic Light Emitting Diodes) monitor, known for its superior color accuracy and contrast.

LED Monitors: An Overview

LED monitors use a panel of LEDs as a light source behind an LCD screen. They offer better image quality and energy efficiency than traditional LCD monitors. However, because they use a backlight, they can’t produce true blacks, which can affect the contrast ratio.

OLED Monitors: An Overview

OLED monitors, on the other hand, use organic compounds that emit light when an electric current is applied. This means each pixel can be individually controlled and turned off completely to produce true blacks, resulting in an infinite contrast ratio.

Key Differences between OLED and LED Monitors

Key differences between OLED (Organic Light Emitting Diodes) and LED (Light Emitting Diodes) monitors.

1. Contrast and Black Levels

The contrast ratio of a monitor is the difference between the brightest color it can produce (white) and the darkest color (black). In OLED monitors, each pixel emits its own light, which means when it needs to display black, it simply turns off the pixel.

This ability to display true black results in an exceptional contrast ratio, often referred to as ‘infinite’. On the other hand, LED monitors use a backlight to illuminate the pixels. Even when displaying black, the backlight can cause a slight glow, meaning the black isn’t truly black, thus resulting in a lower contrast ratio compared to OLEDs.

2. Color Accuracy and Range

Both OLED and LED monitors boast excellent color accuracy. However, due to their unique technology, OLED monitors can display a slightly wider range of colors or color gamut.

The individual control of each pixel allows for more precise color representation, making OLEDs a preferred choice for professionals like graphic designers and video editors who require accurate color reproduction.

3. Viewing Angles

Viewing angle refers to the angle at which you can view the screen without noticeable color distortion or loss in image quality.

OLED technology excels in this area as well. Since each pixel emits its own light and color in an OLED monitor, it maintains color accuracy and contrast even at extreme viewing angles. LED monitors, however, can experience some loss in color accuracy and contrast when viewed from wider angles.

4. Response Time

Response time is the time it takes for a pixel to change from one color to another, usually measured in milliseconds (ms). A lower response time means less motion blur and a sharper image during fast-paced scenes in games or movies.

OLED monitors have incredibly fast response times, often under 1ms, due to the organic compounds that can rapidly respond to electric current. LED monitors, while still fast, typically have slightly higher response times.

5. Lifespan and Burn-in Issues

LED technology is generally considered to have a longer lifespan compared to OLED. One of the challenges with OLED technology is the risk of burn-in. If a static image is displayed for an extended period, it can “burn in” and leave a faint but permanent ghost image on the screen.

However, modern OLED monitors have features to mitigate this issue, like pixel shifting and screen savers.

6. Energy Consumption

Energy consumption varies between the two based on what’s being displayed. OLEDs consume less power when displaying darker images because each pixel only uses power when it’s lit up. In contrast, LEDs use a constant backlight, so their power consumption remains consistent, irrespective of the brightness or darkness of the image.

While both LED and OLED monitors have their strengths, your specific needs and usage will determine which is the best fit for you.

Use Cases: When to Choose OLED or LED

If you’re a gamer or a video editor who values fast response times and high contrast ratios, an OLED monitor would be the best choice. For general use or if longevity is your priority, an LED monitor would serve you well.

Cost Analysis: OLED vs. LED

OLED monitors generally cost more than LED monitors due to the higher manufacturing costs of OLED technology. However, the superior performance of OLEDs can make the extra cost worthwhile for professionals in gaming, video editing, and graphic design.

Future Trends in Display Technology

The future of display technology looks promising, with advancements in both LED and OLED technologies. MicroLED technology, which combines the advantages of both, is on the horizon and could potentially revolutionize the industry.


Both OLED and LED monitors have their strengths and weaknesses. The right choice depends on your specific needs, preferences, and budget. We hope this guide has provided you with a deeper understanding of these two popular display technologies.
