Nano IPS is the improved version of the IPS technology by LG. When applied to the LED backlight of an IPS display, it allows for a wider color gamut of up to 98% DCI-P3 or 135% sRGB.
LG’s Nano IPS technology involves nanoparticles which are applied to a LED backlight of an IPS-panel display. These particles absorb excessive light wavelengths in order to increase color gamut of a display.
In comparison to standard IPS displays which cover ~100% of the sRGB color space, Nano IPS displays have an extended gamut of ~135% sRGB or 98% DCI-P3 which allows them to deliver more vibrant and lifelike colors that are, among other things, essential for an immersive HDR (High Dynamic Range) viewing experience.
When it comes to TVs, LG offers a series of TVs called ‘Nano Cell’ which use the Nano IPS technology.
LG Nano IPS vs Samsung Quantum Dot: TVs
Despite certain advantages IPS offers over VA (more accurate colors, faster response time, and wider viewing angles) panels, the VA technology still provides a higher contrast ratio which is arguably the most important display specification.
In comparison to VA-panel TVs, IPS models don’t have as deep black shades; in fact, they are grayish in comparison.
Furthermore, on some TVs and monitors, Samsung applies a quantum dot film layer between a display’s LED backlight and its panel which, similarly to Nano IPS, increases the display’s color gamut and brightness. These quantum dot displays are referred to as QLED.
Due to the higher contrast ratio of VA panels, QLED TVs are more popular than Nano IPS TVs, but LG has a different display technology called OLED which competes against high-end QLED TVs. Learn more about OLED vs QLED.
LG Nano IPS vs Samsung Quantum Dot: Monitors
As far as desktop monitors are concerned, both QLED and Nano IPS monitors are popular, the choice between the two will depend on the personal preference of the user as well as on other specifications and features the monitor offers.
Due to better color accuracy and consistency as well as wider viewing angles, IPS displays are the best pick for color-critical work.
Since IPS panels also have faster response times, they are favored by those who play fast-paced games whereas VA panel displays offer a higher contrast ratio which is more suited for those who prefer more immersive viewing experience and don’t mind a bit of noticeable trailing caused by fast-moving objects.
Samsung also applied quantum dots to one of their TN-panel displays, the Samsung U28H750. The result was a better image quality in comparison to other TN displays, but the colors and contrast are still not as good as that of equally priced IPS and VA alternatives.
