UHD vs OLED – The Ultimate Comparison

Deciding whether to acquire UHD or OLED screens for your display can be an uphill task. This guide uncovers some interesting facts about UHD and OLED screens.

What is a UHD?

UHD stands for Ultra High Definition. It is a technological term used to categorize television sets with resolutions higher than high-definition TV types.

These televisions come with higher frame rates and display more realistic colors. Ultra-high definition includes 4k, 5k, and 8k resolutions with a 16:9 aspect ratio or wider.

On October 17th 2012, the Consumer Electronics Association, an organization in charge of consumer technology, announced the term Ultra high definition UHD would be used to categorize displays with an aspect ratio of 16:9 and at least a resolution of 4k (3840 × 2160). The Ultra HD forum was formed in 2015. The forum’s main duty was to help resolve any problems encountered during UHD deployment and as such aid in the deployment


What is an OLED?

OLED stands for Organic Light Emitting Diodes. This technology utilizes panels to create lighting as well as images. The first working OLED was built by Chemists Ching Wan Tang and Steven Van Slyke built in 1987 at Eastman Kodak and released in 2004.

These panels do not utilize background lighting as UHDs do. OLEDs use electrical currents to control individual diodes. This function allows it to display great color contrast and even darker blacks

In order for OLED to create a true black pixel simply by turning off the diodes. This design allows it to be used on TVs but also devices that are thinner than traditional TV such as laptops, smartphones, and tablets.

Advantages of UHD vs OLED

Advantages of UHD

The Benefits of using ultra-definition display are;

  • High picture quality. UHD displays have 4 times the number of pixels compared to the regular High definition. Therefore, images even in their lowest resolution which is 4k are clearer, sharper, and much more defined.
  • Larger displays. With UHD even images displayed on larger screens do not tamper with its quality. A larger screen may sometimes be essential in creating a more immersive experience and it is made possible with UHD.
  • Future proof; with 4k resolution will be relevant even in the next five years. Its high quality and highly defined visuals are not likely to be overthrown anytime soon. Although 8K resolution falls under UHD it may require more advanced hardware but for now, Ultra high definition is the future.
  • There is an increasing stream of incoming 4K content with streaming services such as Netflix that are on the rise
  • UHD are relatively cheaper and with a lot of options in the market you can choose one that suits your budget.

Advantages of OLED

The benefits of OLED include

  • OLED displays have high-quality images. It has better color space and contrast ratios as well as better viewing angles. This is because the pixels in the OLED light directly
  • Use of true blacks. The OLED creates images and lighting by switching on individual pixels. Since they have no black light for black the pixels are simply not turned on resulting in a darker black also known as a true black
  • Devices that use this technology are lightweight. The lack of backlights means that the devices can be made thinner. OLEDs also use plastic substrates that are flexible making them more lightweight as well as durable.
  • OLED response time is about 1000 times faster than LCD which is more common with UHD devices.
  • Inactive OLEDs do not produce any form of light. It simply turns off which makes it more efficient when it comes to power.
  • Due to their reduced emission of blue light they are better for the eyes

Limitations of UHD vs OLED

Limitations of OLED

The limitation of OLED include;

  • The devices that OLED tend to be more expensive when compared to their counterparts that use OLED
  • OLEDs are made from organic materials. The materials used have a shorter lifespan due to their nature. Therefore, while expensive OLED can only serve for a limited time
  • It has a poor color balance that develops with time. The materials that are used to create the blue light degrade at a faster pace compared to rest leading to this imbalance.
  • OLED uses more power to function as opposed to UHD displays.
  • It is not ideal for outdoor settings. Since it is made from organic materials they are more prone to water damage. It is also affected by ambient light.

Limitation of UHD

The limitations of UHD include

  • UHD devices have a slower response time compared to OLED. The fastest response time for UHD is one millisecond whereas OLED can be 1000 times faster than a regular UHD.
  • Ultra High Definition devices cannot display true black as light bleeds in from the backlighting when black is displayed
  • Despite the fact that is cheaper than OLED, UHD devices can also be relatively pricy compared to the high definition device
