Difference Between LED And QLED | In Tabular Form | Definition | Updated
We explain that what is the difference between LED and QLED with table? People are confusing a similar word, and they considered that both elements are the same. People often consider both LEDs and QLEDs to be the same; There is no difference between them. Let me clarify that both LED and QLED are very different from each other and have also had different properties.
LED also stands for light emitting diodes. It is also a type of LCD television that uses light-emitting diodes. LED TVs backlight the screen instead of using cold cathode fluorescent lights, which are used in an LCD TV. This TV is more commonly known as an LED backlit LCD TV.
QLED stands for Quantum dot LED television. The quantum dot is actually a display device that uses semiconductor nanocrystals and quantum dots to produce pure monochromatic red, blue, and green lights. QLED television is just an LCD television that can have quantum dots.
The difference between LED and QLED is that LED stands for Light Emitting Diodes. On the other hand, QLED stands for Quantum Dot Light Emitting Diodes.
Comparison Table Between LED And QLED
QLED comparison LED parameter
| Sense | The word LED stands for light-emitting diodes. It also refers to the small, efficient light that light releases when electrical current passes through it. | The word QLED stands for Quantum LED Television. This display device uses semiconductor nanocrystals, which can produce green, blue and red monochrome lights. |
| Image quality | The LED does not offer higher quality images or color volume compared to QLED. | It offers higher image quality and good color volume compared to LED. |
| Energy consumption | LED consumes less electricity compared to QLED. | It consumes more electricity compared to LEDs. |
| Expensive | LED television is more expensive than QLED. | QLED television is less expensive than led. |
| Gloss level | LEDs provide brighter image without consuming more power. | QLED was unable to deliver a minimum brightness level without consuming more power. |
| Contrast level | LEDs can deliver sharper and richer colors along with great dynamic contrast, and they also deliver wider color along with higher light intensity. | QLED also offers more excellent contrast and bright white and true black colors, as in QLED, each pixel has its lights. |
| Technology | The LED uses technology just like the LCD TV, which has light-emitting diodes to illuminate the screen instead of cold-cathode fluorescent lights. | QLED uses quantum dot technology to release light. |
What is an LED?
The word LED stands for light emitting diode. It is also known as small efficient light, which releases light when electrical current passes. It is very different from the CCFL backlit LCD TV in every way. LEDs can produce an image with excellent dynamic contrast and this TV is much thinner compared to LCD TV.
The leading technology behind the development of LEDs dates back to 1960. At that time, a scientist was working on the chip of semiconductor material that soaks impurities in a positive-negative non-junction creating junction. There are two forms of LEDs; one is the white edge LEDs, which are positioned around the entire edge of the screen so that the light spreads even behind the screen by means of a special diffusion panel. Another is the dynamic RGB LEDs that are placed behind the panel.
It is often believed that different techniques have been used. The three most commonly used edge-lit LEDs are the white LEDs that are placed around the edge of the screen, which also extend the panel to illuminate the screen. The second is the Edge illuminated LED display, which is usually very thin. And the third is an RGB LED behind the panel. The RGB LED mainly focuses on the area to be dull more specifically. In RGB LED displays, there is no ability to locate dimming.
What is QLED?
The word QLED stands for Quantum Dot Light Emitting Diode. This TV is treated as the modern generation TV screen, promoted by Samsung for the newest and most advanced excellent LED TV. Sometimes this technology looks like the 90s or something like the term quantum dots, but it is considered the future of the television screen as stated by Samsung in its part of the marketing strategy. It is more than image quality.
Like the term, this technology uses quantum dot technology to release light by giving an additional layer of tiny particles before a normal LED backlight panel, showing better results in rich colors, dynamic contrast, color accuracy, and maximum brightness. It sounds very familiar to the OLED. Well let me clear this up, and it’s a very different technology that allows for over a billion colors.
Main Differences Between LED And QLED
- Both televisions offer pleasant viewing images; if you are in the center of the television, neither of them offers an excellent audience from a very far angle.
- LED television does not offer higher picture quality. On the other hand, QLED television has this advantage, as it offers excellent picture quality compared to LED.
- LED television is more expensive. On the other hand, QLED TV is not that expensive compared to LED.
- LED TVs consume less power and offer maximum brightness levels. On the other hand, QLED was unable to offer minimal brightness without consuming more power.
- LED television uses technology, just like LCD television. On the other hand, QLED television uses Quantum dot technology.
Final Thought
As the main difference between LED and QLED TVs has been said, it is clearly seen that both perform a different function and both use a different technology. LED stands for Light Emitting Diode, while QLED stands for Quantum LED Television.
One offers excellent image quality, consumes less electricity and offers a maximum brightness level, so it is very difficult to know which is better and which is not. It is up to the customer to buy it according to their preferred taste.
