How many watts does a 65 inch led TV use? (2021 Guide)

Although energy efficiency isn’t a decisive factor while purchasing a TV, it is good to consider; thereby, you may decrease the running cost. In the following discussion, we will try to calculate that how many watts does a 65 inch LED TV use?

But before assessing the energy consumption of 65 inch TV, it is important to describe different technologies used in the TV since invention. After that, we will try to evaluate the factors that are reprehensible for energy consumption. Lastly, you will be able to know the exact values of 65 inch TV’s energy consumption.

Main Types of TVs:

Since its inception, TV has improved its shape, technology, and picture quality. Initially, Plasma TVs were introduced. At the beginning of the 21st century, LCD TVs were the talk of the town. And, LED smart TV is the new buzzword nowadays. Let’s check what the difference among all of them is.

Plasma TVs:

First, plasma TVs started to entertain mankind on screen. These TVs are bulkier with no smart features.

The gas tube has been used in these TVs, which emitted light photons when it collided with electrons (energy). And emitting photons are used to generate a picture on a screen. That simple phenomenon consumed too much energy as compared to today’s latest models.


After entering the 21st century, Plasma TVs were converted into LCDs. LCDs were smartly built, which could be mounted on the wall.

LCD works on the principle of pixels that comes into three basic colors Red, Green, and Blue.  There three colored pixels have been controlled by liquid crystal in the screen, which gives you a better result of picture quality.

Compared to plasma TVs, LCDs consume less energy.


LED TVs are the modern smart TVs which are being watched in our houses nowadays. With an enhanced shape and body smartness, LEDs are common items of every home.

The main difference between LED and LCD is the source of light. In LCD, the liquid crystal has been used. On the flip side, LEDs use light-emitting diodes (tiny bulbs) to create a clear image. Moreover, LEDs are supposed to be thinner than LCDs.

Compared to plasma TVs and LCDs, LEDs consume less energy.

Responsible Factors for Energy Consumptions:

In LEDs, there are different factors that make TV energy efficient. Let’s discuss all those factors one by one.


Size is one of the main culprits to increase the running cost of a TV. A bigger TV consumes more energy than a smaller TV.

For example, a 40 inch led TV consumes almost 40 to 50 watts that might costs you $7 in a year (if you watch TV 5 hours a day).

On the other hand, a 65 inch TV consumes almost 90 to 100 watts, costing you $17 to $20 in a year.


Brightness is another factor that might increase energy consumption. Watching TV in a well-lit room requires a high brightness level to enjoy the picture quality.

For a high brightness level, a LED tv needs to turn on more tiny bulbs (source of light), resulting in more energy consumption.

Local Dimming Array:

A local dimming array is a newly introduced feature that gives a high contrast ratio for better picture quality. A local dimming array is good to enjoy dark scenes in movies. Moreover, when you are expected to watch TV in a dark room, the local dimming array offers a perfect contrast ratio.

This feature not only increases the energy consumption but also skyrockets the purchasing price of a LED TV.


Similar to the local dimming array, OLED is a newly introduced technology in TVs. OLED TVs offer perfect brightness level and contrast ratio according to the movie’s scene. And it is observed that OLED TVs consume more energy than simple LEDs.

A simple 65 inch LED tv consumes almost consume 90 watts. On the other hand, a 65 inch OLED consumes almost 120watts.

Energy Consumption of 65 inches LED TV

A 65 inch LED TV consumes almost 90 watts. So, if you watch TV for 5 hours a day, it may cost you $18 to $20 for a year, according to calculations. ($0.11/kWh)
