All TV,s have its own pros and cons,Below are the differentiation of QLED vs OLED vs LED TVs ? then you will find which one best for your requirement.
- LED TVs are great options if you’re on a budget or prioritize screen size over picture quality and color accuracy.
- QLED TVs deliver better color than LED TVs and are perfect for well-lit rooms (like a living room or bedroom with many windows) because they can deliver higher brightness than OLED TVs. However, they’re more expensive than LED TVs.
- OLED TVs are the gold standard for color accuracy and contrast, but this comes at the expense of lower brightness and image burn-in. This option is great if you have a dedicated cinema or TV room or if you’re placing the TV in a room where you can control the amount of light it gets.
| LED | QLED | OLED | |
| Black Level | Excellent | Excellent | Very excellent |
| Gray Uniformity | Decent | Normal | Excellent |
| Brightness | Great | Excellent | Best |
| Color Gamut | Good | Excellent | Very excellent |
| Viewing Angle | Not good | Not good | Excellent |
| Image Retention | Excellent | Excellent | Normal |
| Motion Blur | Good | Great | Perfect |
| Price and Availability | Excellent | Great | Decent |
LED TV
WHAT IS LED?
LED, which stands for light emitting diode, emerged in the TV market before QLEDs and OLEDs. They use LEDs to light up an LCD panel. Many LED TVs have a VA panel, which normally has a high contrast ratio and narrow viewing angles, and they can get very bright.
Who should buy it: Most people looking for TVs today. LED TVs offer the best value and can be found in a very wide range of sizes.
QLED TV
WHAT IS QLED?
QLED TVs use traditional LCD panels lit by LEDs. Between the LCD layer and the backlight, a quantum dot layer filters the light to produce more pure and saturated colors. QLED is a marketing term used by a few companies, like Samsung and TCL, on their quantum dot TVs.
Who should buy it: Those looking for the best colors available.
OLED TV
WHAT IS OLED?
OLED TVs can adjust the luminosity of each pixel individually. This allows them to turn them completely off to show pure blacks. This gives them exceptional picture quality, and they have wide viewing angles.
Who should buy it: Everyone that can afford it, except if you want to use it as a PC monitor or watch a lot of content with static elements.
How LED, QLED, and OLED TVs Work
It’s important to understand how each TV technology works to get into the details of these differences. While LED and QLED TVs work using the same principle, with the latter adding another step to create a better image, OLED TVs work completely differently. So, these are the concepts behind each TV.
LED TVs
- An LED TV runs on the same principle as the first LCD TVs. It’s a flat panel with several layers that control light and color. The bottom layer is usually the backlight unit, which lights up the screen so you can see the image. Instead of using fluorescent or other types of lights, LED TVs use LEDs, hence the term.
- While LED TVs have multiple layers, this is the basics of how it works. The light source—an LED screen—sits at the very back of the television. In front of that, we have a vertical polarizer that only lets vertical light waves through it.
QLED TVs
- QLED TV starts with the same principle as an LED TV—the backlight, vertical polarizer, liquid crystal layer, horizontal polarizer, color layer, and the viewing screen. However, QLED TVs don’t use a white LED backlight. That’s because white LED backlights generally don’t have perfect whites. You can see this if you look at LED light strips; you’ll notice they usually have a yellow tinge.
- To solve this issue, leading QLED TV manufacturer Samsung uses a Quantum Dot layer as its light source. Instead of using white LEDs as its backlight, the company used the LED light source to excite the crystals in the Quantum Dot layer. This layer then emits a naturally white light brighter than the traditional LED source.
OLED TVs
- The main difference OLED TVs have over LED and QLED TVs is how they produce light. Instead of requiring a backlight, the individual pixels on OLED TVs emit light themselves.
- This is unlike LED or QLED TVs, which require a constant power supply to keep the entire backlight layer turned on. If a screen section is black, the liquid crystal layer blocks the light coming from the backlight. While this is enough to reduce the brightness of that particular section, it often leads to some light leaks—usually from neighboring pixels—resulting in a light bloom on your screen, especially if you view a white image on a black background.
- But on an OLED TV, when a section of the screen is black, totally no light is emitted in that part. This is what gives the OLED TV its accurate color and infinite contrast ratio.
Conclusion: finally the winner is OLED TV because used high technology into screen and power emission control.
