What is OLED TV?

OLED stands for Organic Light Emitting Diode. Now, you may be familiar with LED which stands for Light Emitting Diode. This is the most common technology currently being used for Televisions in India. An LED is a small solid-state device that produces light when electrons move through a semi-conducting material. The screen on your Television is usually a Liquid Crystal Display. This display is backlit with LEDs which produce the various colors and illumination required to display pictures on the screen. Now that we know what LEDs are, lets look at how OLEDs have changed the game.

What is OLED TV Technology?
What is OLED TV? Is OLED TV Good?

OLED or Organic LEDs are made of organic compounds that produce light when electricity is passed through them. Organic in this case refers to compounds that have Carbon in them. We will find out more about OLED TVs when we look at the difference between LED and OLED TVs.

What is the difference between OLED and LED TV technology?

LED TVs have a liquid crystal display which is backlit with LEDs. There is a limitation on how small LEDs can be made. Therefore, each LED is much larger than a pixel which is the smallest unit of display on the LCD screen. As a result, the color reproduction using LEDs can never be perfect.

OLEDs on the other hand have much smaller individual LEDs. This leads to much better color reproduction when an OLED panel is used. Lets look at all the benefits of an OLED TV.

What are the benefits of OLED TV?

As we saw above, one of the main benefits of an OLED TV is that the color reproduction is much better. in LED TVs, the backlight from the LEDs is filtered and polarized to show the final picture on the screen. In OLEDs, each individual LED has its own color setting. This leads to more uniform lighting of the screen from edge to edge.

Another consequence of the better color control on OLEDs means that the blacks are much darker on them. Each individual OLED can be made perfectly black. The contrast ratio on an OLED is infinity. As a result, you will find blacks to be much darker and picture popping out in scenes where there is black required to be shown.

Another benefit of OLED screens is that they much thinner then LED TVs. This is due to OLED TVs not requiring as many layers as an LED TV

What are the disadvantages of OLED TVs?

    • Brightness:

OLED TVs might not be as bright as LED TVs. Do check the brightness on the OLED TV model before you purchase

    • Lifespan:

The rated lifespan of OLED TVs is currently lower than LED TV. Although this is improving rapidly, LED TVs are known for lasting a long time and will most likely continue to outshine their OLED counterparts on this.

    • Cost:

Since the technology is still very new, OLED TVs are much more expensive as compared to LED TVs.

OLED TVs – Frequently Asked Questions

Which manufacturers make OLED TVs in India?

Currently, LG, Sony and Metz are the only manufacturers which have OLED TV models available in India. Metz is the latest entrant in this market. Metz is a Germany based TV manufacturing company.

What is the lifespan of OLED TVs?

The claimed lifespan of OLED TVs as per LG is 100,000 hours beyond which the manufacturer says the brightness of the TV will reduce to half.

Are OLED TVs good?

OLED TVs provide advantages like uniform brightness, infinite contrast ratio and deep blacks. The technology is still evolving and is more expensive than LED TVs currently.

What is OLED TV burn in?

Burn-in or image retention refers to when a particular image gets imprinted on the display. This can happen if the same image is shown on he OLED TV for multiple hours or days. Burn in is not a significant problem on OLED TVs. Most modern TVs have a feature of showing screensavers if the same image is statically shown on the TV for a long period of time.

Who invented OLED?

Modern OLED TV technology was invented by Ching W Tan and Steven Van Syke while there were working at Eastman Kodak.

When was OLED invented?

Modern OLED TV technology was invented in 1987 by Ching W Tan and Steven Van Syke while there were working at Eastman Kodak.

Where was OLED invented?

Modern OLED TV technology was invented in 1987 by Ching W Tan and Steven Van Syke while there were working at Eastman Kodak in the United States of America.

Who holds patents for OLED TV technology?

The patent for OLED as a technology expired in 2007 which led to multiple companies exploring opportunities in creating OLED based devices. For TVs today, LG is the largest and most prominent manufacturer of OLED displays. It even provides OLED screens for its rivals like Sony.

Why are OLED TVs expensive?

OLED TVs are expensive since the technolgy is still very new and available to only a few manufacturers. With time we expect the cost of manufacturing for OLED displays to come down as more manufacturers will begin to make them and there will be better economies of scale.

Is OLED better than 4K?

OLED and 4K are fundamentally different technologies when it comes to display. OLED can be compared to LED while 4K can be compared to Ultra HD. 4K is the current most advanced commercially available display resolution available. So if you are looking for an OLED TV, make sure the resolution on it is atleast 4K.
