Understanding QLED Technology

Now that we have explored the basics of QLED technology and how it compares to other TV technologies, let’s dive deeper into how QLED works and the key features that make it stand out.

How QLED works

QLED technology consists of multiple layers that work together to produce images on the screen. The key components of a QLED display include backlighting, quantum dots, color filters, and liquid crystals. When the TV is turned on, the backlight illuminates the liquid crystals, which act as tiny shutters that control the amount of light passing through. The quantum dots, which are located between the backlight and liquid crystals, absorb light from the LED backlight and emit different colors based on their size.

The color filters further refine the light emitted by the quantum dots, resulting in the final color displayed on the screen. By manipulating the intensity and combination of colors emitted by the quantum dots, QLED TVs can achieve a wide and accurate color gamut.

Quantum Dot technology

Quantum Dot technology is at the core of QLED displays. Quantum dots are semiconductor particles that vary in size depending on the color they emit. When these particles are exposed to light, they release photons of different wavelengths, which correspond to specific colors. By using different sizes of quantum dots, QLED TVs can generate a wide range of colors with precise accuracy.

The advantage of quantum dot technology is its ability to produce colors that are more vivid, saturated, and true-to-life compared to traditional LED or LCD displays. The quantum dots used in QLED TVs can reproduce a larger percentage of the color spectrum, resulting in a more immersive and lifelike viewing experience.

Backlighting in QLED

In QLED TVs, the backlighting plays a crucial role in illuminating the quantum dots and allowing them to emit colors. The backlight consists of an array of LEDs (Light Emitting Diodes) that are positioned behind the display panel. These LEDs provide the necessary light for the quantum dots to absorb and emit different colors.

The backlighting in QLED TVs can be either edge-lit or direct-lit. Edge-lit backlighting involves placing the LEDs along the edges of the TV panel, allowing the light to spread across the screen. This design allows for slimmer and more lightweight TVs but may result in less uniform lighting and potential blooming (light bleeding around bright objects).

On the other hand, direct-lit backlighting utilizes a grid of LEDs positioned directly behind the display, providing more accurate lighting control and better overall uniformity. Direct-lit backlighting is commonly found in larger and higher-end QLED TVs, offering superior performance in terms of brightness, contrast, and HDR capabilities.

Color reproduction in QLED

As mentioned earlier, QLED technology excels in color reproduction. The use of quantum dots allows QLED TVs to produce a wider color gamut compared to traditional LED or LCD displays. The wider color gamut means that QLED TVs can accurately depict a larger range of colors, resulting in more vibrant and true-to-life images.

Furthermore, QLED TVs often support color calibration technologies such as HDR (High Dynamic Range) and Wide Color Gamut standards like DCI-P3 or Rec. 2020. HDR allows for more precise control of highlights and shadows, resulting in better contrast and more realistic images. Wide Color Gamut standards expand the range of available colors, ensuring that the TV can reproduce accurate and vibrant hues.

Brightness and contrast in QLED

Brightness and contrast are crucial factors in determining the visual quality of a TV. QLED TVs generally offer higher brightness levels compared to other TV technologies, making them a great choice for well-lit rooms or environments with natural light. The high brightness ensures that the images on the screen appear vivid, even in bright conditions.

In terms of contrast, QLED TVs typically perform well, thanks to the precise control over backlighting and the ability to produce deep blacks. While QLED TVs may not match the absolute black levels of OLED TVs, they can still achieve a high contrast ratio by dimming or turning off individual LEDs in darker areas of the screen.

HDR support in QLED

HDR (High Dynamic Range) is a feature that significantly enhances the visual quality of TVs by optimizing the contrast and dynamic range of the image. QLED TVs are known for their excellent HDR performance, thanks to their ability to produce high brightness levels and deep blacks.
