QLED vs. OLED TV: Similar names, totally different technologies

QLED vs. OLED TV: Similar names, totally different technologies

Wondering which TV is right for you? While LG’s OLED and Samsung’s QLED may sound very similar, there are major differences at the core level.

OLED, which stands for “organic light emitting diodes,” is the top choice for most people. Its technology replaced the need for backlights - which are the lights that shine behind the LCD screen to illuminate them. With OLED, the LED bulbs emit light that creates the picture.

On the other hand, QLED stands for “Quantum Dot LED,” and can be compared to an LCD TV because it uses a backlight. When light reflects onto the quantum dots, they emit light. They also produce a more undiluted light than LEDs. TV experts may roll their eyes at the use of a backlight. But, if you’re in the market for a new TV, here’s what both of them have to offer.


As new technologies hit the marketplace, they are priced at a premium. In time, these electronics become more accessible to the public and the price begins to drop. Today, OLED TVs are pricey but cheaper than when they first debuted. You can purchase an LG 55-inch 2017 OLED B7 and C7 for under $2,000. If you are after a steal, the QLED is the friendlier option for your wallet.

Image Quality

When TV shopping, most of us focus on two things: image quality and the black levels or brightness. The OLED outperforms the QLED because it delivers images with a deeper black tone. The QLED advertises that it has stronger colors than the OLED on screen. While the color may be brighter, the drawback is that when critics tested the Samsung Q7 QLED - especially with HDR material- it underperformed OLED.


OLED and QLED TVs come with added features that can enhance your viewing experience. The LG OLED has Dolby Atmos and DTS Audio. These features create the feeling of surround sound. Four types of high dynamic range are offered: Technicolor, HLG, Dolby vision and HDR 10. And the Alpha 9 Processor creates high-quality images with less movement when the images are not moving.

Samsung QLED features include Ambient mode, which disguises large displays and blends seamlessly into the wall behind it. Also, rather than having the HDMI and USB Ports built into the TV itself, Samsung keeps them in a separate box and then they are connected to the TV through a slim chord. This design element is great for those who want a cleaner and sleeker look to their TV. HDR10+ and HDR Elite create a good picture quality.

Size and Viewing Angle

The OLED can be purchased with a screen size of up to 88 inches. The LCD screen operates with less limitation. So, you can find a wider array of screen sizes with the QLED. The QLED offers screens of up to 100 inches. But, the more aesthetic-centric user will love the thin size of the OLED TV. It’s also lighter and uses less power than the QLED.

The viewing angle refers to how the picture quality remains when you watch the TV from another spot in the room. LG is tough to beat because its IPS Panel has an accurate viewing angle that keeps its picture quality and color.

You can capture the best picture when you sit directly in front of the QLED. But, Samsung has added an updated panel design and anti-reflexive coating to its top of the line models. These two features make up for the dwindled richness and difference in color.

When purchasing your new TV keep these tips in mind, and check back for updates.
