The acronym 'OLED' stands for Organic Light-Emitting Diode - a technology that uses LEDs in which the light is produced by organic molecules. These organic LEDs are used to create what are considered to be the world's best display panels.
OLEDs are organic LEDs, which means that their key building blocks are organic (i.e., carbon-based) materials. Unlike LEDs, which are small-point light sources, OLEDs are made in sheets that are diffuse-area light sources.
OLED stands for organic light-emitting diode and is one of the newer technologies available for TVs and other digital displays.
OLED isn't a new technology; far from it. It first arrived on the scene in 1987, with Kodak developing it for their digital cameras. Little did anybody know that what Kodak had created would bring about so many exciting possibilities in the world of television.
Reduced Power Consumption. As OLED monitors allow pixels to be controlled on an individual level, this means that individual pixels can be turned off completely, leading to reduced power consumption when compared to LED monitors with high brightness settings.
Besides the noted advantages of OLED display, some of the disadvantages include: Shorter lifetime then some other display technologies. This shorter lifetime is mainly due to the blue organic material but lifetime gets better all the time but is also due to moisture migration. Poor sunlight readability.
Drawbacks or disadvantages of OLED
➨Their lifetime is shorter compare to other display types. White,Red and Green OLED offer lifetime of about 5 to 25 years where as blue OLED offers about 1.6 years. ➨It is expensive compare to LCD. ➨It is susceptible to water and hence it can be easily damaged by water.
The lifespan of OLED TVs is a common concern among consumers, but the technology has proven to be reliable and durable. OLED TVs are known to have a lifespan of around 100,000 hours, which is equivalent to over a decade of use (with an average of 8-10 hours of watching hours daily).
OLED has a significantly wider and better viewing angle when compared to 4k UHD LED TVs. Unlike LEDs that still have shutter issues because of screen pixels, OLED comes with advanced pixels powered by self-illumination capabilities. Thus, OLED is a clear winner in this department.
In terms of picture quality, OLED TVs are generally considered to be the better option due to their perfect blacks and infinite contrast. However, QLED TVs can still produce very high levels of brightness and colour accuracy, and they are often more affordable than OLED TVs.
An OLED TV is not only beneficial for better sleep by emitting lower levels of bluelight but also a better choice to minimize eye strain as it is free from flickers or glares.
But Why Are OLED TVs So Expensive? The main reason that OLED TVs are so expensive is that they OLED is a young technology, and manufacturing OLED TVs is difficult. This is especially true of OLED panels large enough to be used in consumer TVs, which only LG Display currently makes.
An OLED display have the following advantages over an LCD display: Improved image quality - better contrast, higher brightness, fuller viewing angle, a wider color range and much faster refresh rates. Lower power consumption. Simpler design that enables ultra-thin, flexible, foldable and transparent displays.
Reducing daily exposure with OLED TV is a good choice because they emit less blue light overall than traditional LCD televisions.”
Because OLEDs prefer darker images, they are less efficient at displaying white images. However, the white images an OLED can display are of higher quality and brightness, but in doing so, this requires more energy consumption than LCD.
Black Levels
OLED is a self-emissive technology, meaning each pixel can turn on and off on its own. When the pixel turns off, you get true black.
QLED displays handle motion better than OLEDs since most QLEDs offer variable refresh rates (VRR) and low input lag. Also, QLED TVs are generally less expensive and readily available in most markets, unlike QNED displays.
The successor to the 4K display resolution is 8K resolution. 8K resolution has four times the number of pixels as a 4K display while 8K TV has a resolution of 7680 x 4320, so an 8K screen will be able to show images with much more detail and clarity than a 4K TV. The first 8K TVs were introduced at CES 2019.

If you use your OLED TV in this manner, or if you use it as a monitor, you are at higher risk of burn-in than the average consumer. We recommend turning your TV off periodically in order to give its pixels a rest.
OLED TVs have great picture quality; however, there are concerns about their long-term performance due to the possibility of permanent image retention, commonly referred to as burn-in. Our previous 20 hours per day burn-in test ran for a little over two years, and the OLED TV has permanent image retention.
"To avoid the possibility of burn-in, consumers should avoid leaving static images on an OLED screen for long periods of time. For example, leaving a video game paused onscreen for several hours or days," a Sony spokesperson said.
The organic material in OLED TVs (OLED stands for “Organic Light Emitting Diode”) potentially wears out over time. It is for this reason in part that Samsung decided to stop using OLED technology in its TVs in 2012 and proceeded to develop the new QLED technology.
Measuring around 4mm thick, it is thinner than LCD panels and displays more-vivid pictures than LCD TVs. TVs based on OLED technology have a slender design due to the use of an organic material that emits its own light. LCD TVs require a backlight, which takes up space at the back of the panel.
One of the simplest ways to protect your OLED TV from burn-in and image retention is to adjust the settings according to your viewing habits and preferences. For example, you can lower the brightness, contrast, and OLED light levels to reduce the stress on the pixels and extend their lifespan.
