Read on to find out which advanced display tech comes out on top in this head-to-head battle.

Display Technology Overview

LCD and LED TVs utilize liquid crystal display (LCD) panels to produce images. An LCD panel contains a layer of liquid crystals between two polarized panels. When an electric current is applied, it causes the liquid crystals to twist and untwist, varying the amount of light that passes through.

On LCD TVs, fluorescent lamps called cold cathode fluorescent lamps (CCFLs) provide the backlighting. LED TVs use light emitting diodes (LEDs) for the backlight instead. LEDs are more energy efficient and allow for thinner display designs.

Both LCD and LED TVs filter the backlight using red, green and blue color filters to produce the colors on screen. The technology behind the liquid crystal layer and color filters determines factors like viewing angles, brightness, color accuracy and more.

What is Crystal UHD?

Crystal UHD is Samsung's marketing term for its premium line of SUHD TVs that utilize quantum dot technology. Samsung introduced Crystal UHD in 2016 to differentiate its high-end LED TVs that feature quantum dots in the display panel.

Quantum dots are tiny semiconductor particles just a few nanometers wide that emit pure monochromatic light when excited. By precisely tuning the size of the quantum dots, manufacturers can produce quantum dots that glow a specific color. This allows for much more accurate and saturated colors in a display.

Samsung claims that its Crystal UHD TVs can produce over 1 billion color shades and 100% color volume for exceptionally vivid and lifelike images. The quantum dots create a wider color gamut, meaning the TVs can reproduce more colors than standard LED displays. This expanded range of colors gets closer to replicating all the shades the human eye can perceive.

The quantum dot layer in Crystal UHD TVs sits between the LCD panel and backlight. It converts the white LED backlight into pure red, blue and green light at the pixel level for optimal color precision in the image. This local dimming of the backlight allows for deep blacks and excellent contrast as well.

So in summary, Crystal UHD is Samsung's branding for its high-end SUHD TVs that use quantum dot nanocrystal technology to deliver superior color accuracy, saturation and brightness compared to standard LED TVs. The quantum dots enable next-level picture quality that Samsung markets as Crystal UHD.

What is NanoCell?

NanoCell is LG's proprietary term for their quantum dot LED TVs. Quantum dots are tiny semiconductor particles that are integrated into the LED backlight system. When illuminated, quantum dots emit very specific wavelengths of light which leads to purer, more saturated colors on screen.

LG leverages this quantum dot technology in their NanoCell TVs to produce a wider color gamut. This expanded range of colors allows for more accurate color reproduction and increased color volume. The quantum dots enable the NanoCell TVs to cover over 90% of the DCI-P3 color space, which is the standard color space for cinema.

In addition to quantum dots, NanoCell TVs also utilize LG's NanoColor and NanoBlack technology. NanoColor involves applying a uniform phosphor coating to the LEDs which helps improve color accuracy. NanoBlack is a filter that absorbs ambient light and reduces reflections, resulting in deeper blacks on screen.

Overall, NanoCell is LG's branding for their lineup of TVs that leverage quantum dots along with other specialized nanometer technologies to deliver enhanced color, contrast and image quality. The expanded color volume and accuracy makes NanoCell well-suited for HDR content and reproducing cinematic visuals in the home.

Quantum Dots Explained

Quantum dots are tiny semiconductor particles just a few nanometers in size that can produce exceptionally pure and intense colors. They work by precisely controlling the size and shape of the quantum dots in order to finely tune the color of light they emit.

Smaller-sized quantum dots emit shorter, blue light wavelengths, while larger dots emit longer, redder wavelengths. By creating quantum dots of very precise dimensions, manufacturers like Samsung and LG can produce pure monochromatic red, blue, and green light.

These narrow-spectrum quantum dot colors are brighter and more saturated than standard LCD displays. They expand the color gamut capabilities of the screen, providing the ability to produce over a billion color combinations for vivid, true-to-life images.

Quantum dots also amplify brightness. They act as a lens to collimate the backlight from the LED source, focusing and intensifying the light. This increases luminous efficiency and allows quantum dot displays to deliver higher peak brightness for HDR content.

Overall, quantum dots enable LCD panels to produce images with wider color gamuts, more accurate colors, better contrast, and increased brightness compared to conventional LCDs. This makes them well-suited for high-end 4K and 8K TVs aiming for premium picture quality.

Crystal UHD vs NanoCell Color

Both Samsung's Crystal UHD and LG's NanoCell technologies aim to produce more vivid, accurate colors on their LCD displays. They take different approaches to achieve this.

Samsung's Crystal UHD relies on quantum dot technology to widen the color gamut. Quantum dots are tiny nanocrystals that can produce very pure colors when illuminated. By incorporating a quantum dot film into the LCD backlight, Samsung can produce colors that are more saturated and go beyond the typical Rec 709 color space. This allows their displays to cover 95-100% of the DCI-P3 wide color gamut used in digital cinema.

LG's NanoCell technology uses nanoparticles to absorb excess light wavelengths and purify the color output. This helps produce more accurate colors within the Rec 709 color space, covering over 70% of DCI-P3. NanoCell aims for color accuracy while Crystal UHD aims for a wider, more vivid color gamut.

In real-world performance, the quantum dot-enabled Crystal UHD TVs can produce more saturated, vivid colors due to their expanded gamut. But some tests show NanoCell TVs produce slightly more accurate colors overall. So Crystal UHD provides a more dynamic, vibrant picture while NanoCell produces subtler, more natural looking colors.
