OLED (Organic Light Emitting Diode) and QLED (Quantum Dot Light Emitting Diode) are two different technologies used in the production of modern TVs. Both have their own unique set of characteristics and features, and they offer different benefits to the users. In this article, we will compare OLED and QLED TVs and try to understand the differences between them.
OLED TV:
OLED TVs use organic compounds that emit light when an electric current is passed through them. These organic compounds are placed between two conductors, and when an electric current is applied, it causes the organic molecules to emit light. The main advantage of OLED TVs is that they can produce deep blacks and have an infinite contrast ratio because each pixel in an OLED TV can be turned off completely, resulting in perfect black. This results in a more lifelike and immersive viewing experience.
Another advantage of OLED TVs is that they have a wide viewing angle. The image quality remains consistent even when viewed from an angle, which is not the case with LED TVs. OLED TVs also have a fast response time, which means that they can display fast-moving action scenes with minimal motion blur.
QLED TV:
QLED TVs use Quantum Dot technology, which is a type of LED technology that uses microscopic particles called Quantum Dots to produce light. These Quantum Dots are placed in a layer between the LED backlight and the LCD panel. When the LED backlight shines on the Quantum Dots, they emit light of a specific color. The color of the light depends on the size of the Quantum Dots.
QLED TVs have a wider color gamut than OLED TVs, which means that they can produce more vibrant and saturated colors. QLED TVs also have a higher peak brightness than OLED TVs, which makes them better suited for use in well-lit rooms.
One of the main advantages of QLED TVs is that they have a longer lifespan compared to OLED TVs. OLED TVs tend to degrade over time, and the organic compounds used in their production can break down, resulting in a loss of brightness and color accuracy. QLED TVs, on the other hand, do not suffer from such degradation, and they can maintain their performance for a longer period of time.
One of the main disadvantages of QLED TVs is that they have a limited viewing angle. The image quality degrades as you move further away from the center of the screen, and this can be a problem if you have a large room or if you have multiple people watching the TV from different angles.
Another disadvantage of QLED TVs is that they cannot produce perfect blacks like OLED TVs. This is because the LED backlight used in QLED TVs is always on, and it cannot be turned off completely. As a result, the blacks produced by QLED TVs are not as deep as those produced by OLED TVs, and the contrast ratio is not as high.
Conclusion:
In conclusion, OLED and QLED TVs are two different technologies used in the production of modern TVs, and they have their own set of advantages and disadvantages. OLED TVs have an infinite contrast ratio, wide viewing angle, and fast response time, but they have a shorter lifespan and may suffer from degradation over time. QLED TVs have a wider color gamut, higher peak brightness, and longer lifespan, but they have a limited viewing angle and cannot produce perfect blacks. Ultimately, the choice between an OLED and QLED TV will depend on your personal preferences and needs.
