Both LED screens and OLED screens are known for their energy efficiency, brightness and vibrant, realistic colors. So what are the similarities and differences between LED and OLED? Next we’ll delve into the intricacies of the differences between the two technologies, as well as reveal their respective strengths and weaknesses.
What is LED
LED(stands for light-emitting diode) is a display technology that is widely used in the manufacture of flat-panel displays used in a variety of modern electronic devices such as televisions and monitors.
LEDs produce light through the movement of electrons in a diode. As the electrons move, they fall into oppositely charged areas, releasing energy. LED monitors are usually composed of an LCD panel and a backlight panel based on light-emitting diodes.
What is OLED
OLED(stands for Organic Light Emitting Diode) is also one of the modern display technologies, which is widely used in a variety of electronic display devices. OLED displays are composed of organic semiconductor compounds, a thin layer of organic semiconductor material sandwiched between two conductive electrodes, when the power supply is connected to the electrodes, the current will flow through the organic light-emitting diode.
When power is connected to the electrodes, an electric current flows through the organic material, producing bright light to illuminate the screen. For this reason, OLED displays are considered to be self-luminous.
Advantages and Disadvantages of LEDs and OLEDs
Traditional LEDs use inorganic light-emitting materials, while OLEDs use organic molecules. Different materials have different advantages. So understanding the advantages and disadvantages of OLED technology and LED technology can help you choose the right technology for you.
Advantages of LED
In terms of durability and longevity, LED technology is known for its long life time and is generally more durable than OLED panels. And LEDs are less prone to screen burn-in and residual images, making them ideal for applications that display static images for long periods of time, such as signage, billboards, clocks, or appliances in the home, to name a few.
In terms of cost, because of the simplicity of the technology, flat and can also use cheaper materials, the cost of LED equipment is significantly reduced. So the manufacturing and purchasing costs of LED monitors tend to be lower than OLEDs, and the price is cheaper and more affordable. Its lower cost becomes one of its advantages.
In terms of brightness, LED monitors are generally brighter than OLED monitors, which means that LED monitors are an ideal choice when ambient light conditions are adequate.
In terms of energy efficiency, both OLEDs and LEDs are energy-efficient compared to traditional lighting solutions, though. But in many applications, LED technology tends to consume less power than OLEDs, especially in bright and well-lit environments, where the higher brightness of LEDs can be utilized without a significant increase in power.
Disadvantages of LEDs
In terms of black level, LEDs are not the same as OLEDs; LED monitors require backlighting, which means that there is no way for LEDs to achieve true black levels. Even with advanced LED dimming technology, LED monitors have difficulty rendering deep blacks, which tends to reduce overall contrast and visual quality, especially in dark scenes.
By design, because LED monitors require backlighting, LED monitors will be much thicker than OLED displays. Even though the latest innovations such as edge-lit technology reduces the thickness, it still can’t match the ultra-thin design of OLEDs.
In terms of color accuracy and viewing angles, LED color reproduction and viewing angles are relatively lacking compared to OLED. Color and brightness may change as the wide angle changes, which can cause the overall image to potentially lose clarity.
Advantages of OLED
In terms of viewing angle quality, OLEDs have pure blacks, vibrant colors and high contrast, so OLED technology provides superior visual quality. Since each pixel of the OLED is self-illuminated, it can be turned off completely, enabling perfect black levels and enhanced contrast unmatched by traditional LED technology.
By design, OLED panels do not require a backlight, making them thinner and lighter than LED monitors. This makes flexible monitors possible, enabling innovations such as foldable, bendable and curved screens. It is also ideal for modern high-end devices such as only cell phones, TVs and bandable devices.
In terms of viewing angle, OLED monitors are able to provide a better and wider viewing angle, which means that the image quality is consistent even when viewed from the side, but on LED monitors there can be such a thing as color casts and reduced brightness due to the wider angle.
In terms of response time, OLED screens have a faster response time than traditional LED screens for playing high-frequency dynamic content such as video games and fast-paced videos. The faster refresh rate of OLEDs is beneficial in reducing motion blur.
Disadvantages of OLED
Image-wise, one of the obvious disadvantages of OLED technology is screen burn-in or image residue, which is more likely to occur when still images are displayed for long periods of time. This can cause some pixels to deteriorate faster than others, resulting in permanent ghosting on the monitor.
In terms of manufacturing costs, the more complex organic materials used in OLEDs and the precision required in the production process make OLED displays more costly to build than LCD displays. This can cause OLED products such as TVs and smartphones to be more expensive for consumers.
In terms of brightness, OLED displays typically have a lower peak brightness compared to LED displays. This can be a disadvantage if used in very bright environments.
Difference between LED and OLED
As mentioned above, both LED and OLED screens have their own strengths and weaknesses. So let’s dive into the differences between LED and OLED next.
Black Levels
OLED displays have higher black levels than LED monitors because there is no backlight. Since the LED backlight is always on, they should tend to always let in a small amount of light even when the screen should remain black.
Some people will feel bad about this phenomenon of light leakage as it can affect the experience of watching movies and videos as well as playing games.
OLEDs are capable of rendering perfect black levels because every pixel of an OLED is switchable off in dark scenes. Localized dimming has good contrast on LEDs, but it does not have the same black levels as OLEDs.
These differences represent that OLEDs are able to render more realistic shadows and depth in low light scenes. So as far as black level is concerned, OLED is better than LED.
Price
OLED displays use more complex technology, OLED displays are better quality and will cost more to produce. So it is more expensive than LED monitors.
There is also the fact that LEDs last longer than other display technologies, thus saving on maintenance and repair costs. Casually if you consider the durability and longevity of LED monitors, the price difference becomes even more pronounced.
Brightness and HDR Performance
LEDs outperform OLEDs in terms of brightness. LED screens are extremely bright, making them ideal for rooms with lots of natural light.
Conversely, OLEDs are better in normal or low-light conditions, showing more pronounced blacks and sharper HDR. OLED displays are able to show more detail and contrast than LEDs.
Aging
OLED displays are known to suffer from “screen burn-in”. Burn-in refers to the fact that although the light source disappears, the image remains on the screen due to the nature of OLED light emission.
Because OLED relies on a single light source, a single light source of bright light will gradually age over time, the light source will become dark. Especially when used more frequently than other light sources, it causes the image to stay on the screen for a longer period of time, and the image outline is blurred or has unknown spots and other problems.
LED monitors are less prone to screen burning because they are powered by a single backlight source, and the brightness of LED monitors dims over time and evenly, so that the entire screen becomes darker, not just a certain area.
Durability
LED monitors are more durable and less prone to screen burn-in than OLED displays, and LEDs can also display static images for long periods of time. However, OLEDs are still prone to screen burn-in when displaying static content. Therefore, LED monitors are usually more durable and can last a long time even with frequent use.
Lifespan
Since OLEDs use organic materials, years of use may also affect the performance of the pixels, which affects the way the light is emitted, and the picture quality deteriorates over time.
LEDs are less prone to screen burn-in because they use backlighting, but also because the backlighting illuminates the molecules, and the LED pixels don’t wear out as quickly. This explains why LEDs are more durable and have a longer mission life than OLEDs.
Energy Efficiency
OLED and LED, both of which are currently considered among the most energy-efficient display technologies, provide bright, high-quality visuals while also minimizing functional consumption.
However, there are still differences between the two because of the different nature of the lighting. LED Compared to OLED, LEDs consume more energy than OLEDs because they use backlighting.
Response Time
Compared to LED, OLED has a fast response time, allowing for lightning-fast pixel transitions, which is good for eliminating motion blur and providing crisp, clear images. OLED displays have a faster response time, which makes them ideal for fast-moving content such as games.
Contrast
The difference between the brightest and darkest parts of an image displayed on a screen is called the contrast ratio. OLED technology offers unlimited contrast because each of its pixels is capable of emitting light independently, so the contrast ratio is extremely high.
LED monitors also offer good color accuracy and vibrancy, but the quality varies depending on the specific display technology used.
Viewing Angle
No matter from which angle we view the OLED, we can see its vivid and bright colors. Even if the viewing angle changes dramatically, you won’t notice any significant color distortion.
But for LEDs, the viewing angle is really quite important. When the viewing angle of an LED monitor changes, the color, contrast, and brightness are all affected to varying degrees.
