OLED vs. LCD: A Comprehensive Comparison

What is OLED, and what is LCD?

Liquid Crystal Display (LCD) and Organic Light Emitting Diode (OLED) are two popular display screen technologies today. They serve as the foundation of modern screen technology, appearing in everything from mobile phones and tablets to large-screen televisions and computer monitors. However, in recent years, a debate has erupted over which is superior: OLED or LCD.

Let's start with a quick overview of how these displays are organized. To generate an image, LCDs use a backlight that shines through liquid crystals. The amount of light that passes through these crystals determines the color and brightness of the pixels. OLEDs, on the other hand, are made of organic material that emits light when an electric current is applied to it. An OLED display generates its light, eliminating the need for a separate backlight.

Contrast Ratio and Black Levels:

OLED technology outperforms LCD in terms of contrast ratio and black levels. OLEDs can achieve pure blacks by simply turning off individual pixels because each pixel on an OLED screen is independently lit. As a result, the contrast ratio is incredible. LCDs, on the other hand, emit some light even when attempting to display black, resulting in a lower contrast ratio regardless of the backlight technology used.

Color Accuracy and Saturation:

Both OLED and LCD have excellent color accuracy and saturation. Due to their ability to regulate light emission at the pixel level, OLEDs typically have a slight advantage in this area. Deeper blacks and more vibrant colors are produced as a result of this careful control. However, improvements in LCD technology, particularly in Quantum Dot LCDs (QLEDs), have made it possible for these displays to match OLEDs' color performance almost exactly.

Viewing Angles:

Another crucial component of display quality is viewing angles. This refers to the variety of viewing angles that the screen can be viewed from without the quality of the image being compromised. OLED screens have nearly ideal viewing angles due to the way that each pixel emits light. However, when viewed at acute angles, LCDs can exhibit decreased color accuracy and contrast.

Lifespan and Burn-In:

However, when it comes to lifespan and burn-in, LCDs do have an advantage over OLEDs. OLED displays' organic components may deteriorate over time, shortening their useful lives. Additionally, OLED screens are susceptible to burn-in, which results in ghost images becoming indelible imprinted on the screen, if static images are displayed for an extended period. LCD screens are less prone to these problems because they don't rely on organic materials.

Energy Efficiency:

LCDs frequently excel in the area of energy efficiency. In cases where LCDs are used to display bright images or white backgrounds, they typically use less power than OLEDs. OLEDs can turn off individual pixels, which means they use less power when there are dark or black images on the screen.

It is evident from a comparison of OLED and LCD that each has advantages and disadvantages. OLED displays offer almost perfect viewing angles, better color accuracy, and superior contrast ratios. They might have a shorter lifespan than LCDs, though, and they might be more prone to burn-in. While this is going on, LCDs have enhanced color performance, are typically more energy-efficient with bright images, have a longer lifespan, and are less prone to burn-in.

In the end, the decision between OLED and LCD comes down to the particular use case and personal preferences. OLED might be a better option if you want the best picture quality and don't care about burn-in or lifespan. An LCD might be the better choice for users seeking a balance between performance, energy efficiency, and durability.

Compared to LED TVs, OLED TVs are renowned for their superior color accuracy, deep blacks, and almost ideal viewing angles. OLEDs can achieve higher contrast ratios—essentially "infinite" contrast—because they are self-emissive. OLEDs also have faster refresh rates, which create smoother motion—a crucial feature for watching action or sports broadcasts with rapid-fire action. The cost of OLED TVs is typically higher than that of LED TVs. Additionally, there is a chance for burn-in over time, particularly if static images are shown for long periods.

Compared to OLED TVs, LED TVs are typically more affordable and have higher brightness levels. LED TVs are essentially LCD TVs with LED backlights. They have a longer lifespan overall and are less prone to burn-in. The main disadvantages are lower contrast ratios, less accurate color reproduction (especially in comparison to more expensive OLEDs), and smaller viewing angles.

OLED vs. LCD computer monitors

OLED displays offer high contrast ratios, quick response times, and excellent color reproduction for computer monitors. For those who need accurate color representation, such as graphic designers, photographers, and video editors, they are perfect. However, over time, burn-in can occur as a result of the static interface elements (such as the taskbar and window borders). OLED monitors are also typically more expensive than their LCD equivalents.

LCD monitor performance has improved significantly, especially for models with LED backlighting. They are generally less expensive, have better color accuracy, and are much less likely to burn in. High-end LCD monitors are favored for gaming because they provide features like fast refresh rates and adaptive sync technologies. They fall short of OLEDs in terms of contrast ratio and black levels, though.

Industrial, military, maritime, home appliances, and medical equipment

Because of their lower price and longer lifespan, LCDs have historically been the preferred option for in-home appliances and industrial devices. They work well in a variety of lighting situations and resist burn-in, making them appropriate for appliances that frequently display static images.

The decision between OLED and LCD may be more influenced by the application's specific needs in the military, marine, and medical fields. OLED displays can be helpful in circumstances that call for quick, accurate image interpretation due to their wide viewing angles and high contrast ratios. However, LCDs might be preferred in situations requiring longevity and durability or in bright environments.

OLEDs' exceptional color accuracy and contrast can help medical professionals interpret medical images correctly. High-end medical monitors, on the other hand, frequently use specialized LCD technology that, despite costing more, can perform on par with or better than standard commercial OLED displays.

In the end, choosing between OLED and LCD for a particular application should take into account the specific needs and limitations of that application. The best option may depend on several variables, including price, viewing angles, color accuracy, brightness, lifespan, and burn-in susceptibility.

The key differences between OLED and LCD and how they are used in TVs, computer monitors, and other devices are outlined below.



OLED displays use pixels that are self-illuminated, whereas LCDs produce images by passing a backlight through liquid crystals.

In terms of contrast ratio and true black levels, OLED displays outperform LCDs, which always emit some light even when displaying black.
