OLED TV vs QLED TV: What are the differences, how do they work and more – Times of India

OLED (organic light-emitting diode) and QLED (quantum dot LED) are both types of display technologies used in televisions. The main difference between the two is the way they produce light. Here we explain what they are and how the two display tech differ
How does OLED work?
OLED TVs use a layer of organic materials that emit light when an electric current is applied to them. This means that each individual pixel in an OLED display can turn on and off independently, producing perfect blacks and infinite contrast. OLED TVs also tend to be more energy efficient and have a wider viewing angle than other types of TVs.
How does QLED work?
QLED TVs, on the other hand, use a layer of tiny semiconductor crystals called quantum dots that emit light when excited by a backlight. This means that QLED TVs do not have the same perfect blacks and infinite contrast as OLED TVs, but they can still produce very high levels of brightness and colour accuracy. QLED TVs also tend to be more durable and have a longer lifespan than OLED TVs.
What is the difference between picture quality?
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.
In addition, QLED TVs with the local dimming feature have an edge over OLEDs. This feature divides the screen into small zones, each with its own LED backlight. This allows for better control of the image and deeper blacks.

Which tech will last longer and is more durable?

In terms of durability and lifespan, QLED TVs are generally considered to be more reliable than OLED TVs. OLED TVs are susceptible to burn-in and image retention, which can occur when the same image is displayed on the screen for an extended period of time. QLED TVs, on the other hand, do not have these issues.
Which is better?
Ultimately, the choice between an OLED TV and a QLED TV will depend on your personal preferences and budget. If you want the best possible picture quality and don’t mind paying a premium, an OLED TV may be the better option. But if you’re looking for a high-quality display that is more affordable and reliable, a QLED TV may be the way to go.
