What are QLEDs and OLEDs?
Introduction to QLED Technology
QLED (Quantum Dot LED) is a technology that enhances the display effect by using quantum dot material, which can precisely adjust the color of light to enhance color performance and brightness. Quantum dot material can precisely adjust the color of light to enhance color performance and brightness.QLED screens rely on a backlight source and use a layer of quantum dots to finely adjust the backlight to produce a more vibrant and brighter picture.QLED technology has the following features:
- High Brightness:QLED displays are capable of delivering higher brightness (peak brightness up to 2000 nits or more), which ensures that the picture is clearly visible even in bright environments.
- Wide Color Gamut:QLED's color performance covers close to 100% of the DCI-P3 color gamut, enabling more vibrant and realistic images.
- Long Lifetime: Due to the stability of the quantum dot material, QLEDs have a long lifespan (typically more than 100,000 hours) and a slow decay in screen brightness.
Introduction to OLED Technology
OLED (Organic Light-Emitting Diode) technology avoids the need for backlighting required in conventional display technology by emitting light independently from each pixel. This unique design allows OLEDs to offer the following benefits:
- Infinite Contrast:OLED screens are capable of rendering deep blacks (close to 0 nits) and perform particularly well in high-contrast scenes, such as starry skies or dark night scenes.
- Ultra-thin design: Since no backlight is required, OLED displays can be as thin as a few millimeters, making them suitable for more compactly designed devices.
- Flexibility:OLED technology also supports flexible displays, which can be used in curved or bendable screen designs (e.g. folding screen phones).
This makes OLEDs particularly suitable for use in low-light environments, such as bedrooms or home theaters, where they can provide a more immersive visual experience.
Core differences between QLEDs and OLEDs
Difference in Light Emitting Principle
One of the core differences between QLED and OLED lies in their light-emitting principle. qLED technology relies on the support of a backlight source and enhances color performance and brightness through quantum dot materials. In QLED displays, the backlight is regulated by quantum dot materials, which precisely control the color of the light, resulting in a more vivid and brighter display.
In contrast, OLED technology is self-illuminating for each pixel and does not rely on a backlight at all.OLED panels are made up of organic materials that emit light when an electric current is passed through them. As a result, the brightness and color of each pixel can be adjusted independently and without the intervention of a backlight. This self-luminous technology allows OLED displays to offer higher contrast ratios and perform particularly well when displaying black colors, as black pixels do not emit any light at all, rendering an extremely pure black.
Brightness and Contrast
Brightness and contrast are key factors in display performance. In terms of brightness, QLED is better suited for bright environments as it can achieve higher brightness due to the design of its backlight source. Whether it's a sunny living room or an occasion that requires a strong picture display such as watching a sporting event, QLED's high brightness ensures that the picture is clearly visible.
OLEDs, on the other hand, have a relatively low brightness that makes them more suitable for use in dim light environments. As each pixel of OLED can emit light independently, it is able to achieve complete black when displaying dark images, a high contrast ratio that QLED cannot achieve.The black performance of OLED is particularly good, providing users with higher picture depth and a stronger sense of immersion, especially when watching movies, documentaries and other dark-light scenes, which provides a better visual effect.
Applicable Scenes and Viewing Experience
According to the characteristics of the display technology, QLED and OLED are suitable for different viewing scenarios.QLED technology is ideal for use in bright environments due to its high brightness. For example, if there is a lot of natural light shining in the living room, QLED is able to provide clear and bright images, ensuring that details are not lost. In addition, QLED's high brightness and strong color performance make it ideal for watching sporting events and fast moving images. It is able to clearly display details in motion, ensuring that viewers can follow every action in real time.
OLED technology, on the other hand, is better suited for home theater, low-light environments, and movie viewing, where OLED's self-illuminating properties make it unmatched in black performance, making it especially suited for watching night scenes or movies with dark backgrounds. Whether it's the starry sky in a sci-fi movie or the dark shadows in a suspenseful movie, OLEDs are able to present deeper blacks, enhance the level of detail in the picture, and bring a more immersive viewing experience.
Screen life and stability
Although QLED and OLED have their own distinctive display effects, there are significant differences in their screen lifespans.QLED has a longer lifespan due to the strong stability of the quantum dot material used, which is able to maintain a good display effect for a long period of time. This technology is less susceptible to light decay or aging, so users can enjoy a longer quality viewing experience.
Unlike QLEDs, OLEDs use organic materials, which will gradually age over a long period of time, resulting in a decrease in brightness and color shifts. Especially when displaying static images for a long time, OLED screens may experience the so-called “screen burning” phenomenon, that is, the outlines of certain images will remain on the screen for a long time. Although modern OLED screens have mitigated this problem through technological means, they have a shorter lifespan than QLEDs and require more frequent maintenance and careful use.
Energy consumption and efficiency
Energy consumption is also a key difference between QLEDs and OLEDs. Because QLEDs rely on a backlight, their energy consumption is relatively high, especially in the case of high-brightness displays, where the backlight consumes more power. OLEDs, on the other hand, emit light independently for each pixel, and black pixels do not emit light, so OLEDs consume less energy when displaying dark content.OLED screens are able to conserve power and improve energy efficiency when displaying black images. This is especially true when using dark-themed apps or viewing dark scenes, where OLEDs exhibit lower power consumption.

Why is display technology critical to picture quality?
Core elements of picture quality
Picture quality is determined by a number of factors, including resolution, contrast ratio, color performance, and brightness. Each of these factors is closely related to the display technology and has a direct impact on the viewing experience:
- Resolution:4K resolution (3840 x 2160 pixels) allows for more detail, such as the texture of a person's skin or the foliage in a landscape.
- Contrast ratio:High contrast ratio (e.g. infinite contrast ratio of OLED) can make the dark details in the picture clearer and enhance the depth of the picture at the same time.
- Color Performance:Wide color gamut (e.g. QLED's DCI-P3 coverage) directly affects the realism and beauty of the picture, especially in nature documentaries, where color accuracy is critical.
- Brightness: High brightness (e.g. QLED's 2000 nits peak brightness) ensures that the picture remains visible in bright environments and avoids reflective interference.
