A Misryoum display demo highlights potential color crosstalk on RGB LED TVs, compared with super quantum dot mini-LED.
RGB LED TVs are being marketed as the next leap in color, but a Misryoum demo at Display Week put a spotlight on a problem that can quietly show up in everyday viewing: color crosstalk.
At the Los Angeles Convention Center, two 85-inch sets sat side by side in a comparison setup.. One TV used mini-LED with super quantum dots, while the other relied on an RGB LED backlight system.. Both were shown the same content in the same mode settings to make differences easier to see. and the results raised questions about how precisely RGB backlights can keep colors contained.
Insight: Color crosstalk matters because it can nudge nearby tones in ways that viewers may interpret as “off” skin color or slightly washed highlights, especially in scenes with strong contrast.
In an RGB LED design. red. green. and blue LEDs are arranged in zones and used to generate colored backlighting that matches what’s on screen.. The trade-off is that light meant for one zone can spill into neighboring areas when colors are adjacent. creating a visible shift.. In the Misryoum demo. a thin white cross pattern over a grid of colors was used to reveal how surrounding colors changed intensity and saturation when that high-contrast element appeared.
Misryoum’s walkthrough showed that the effect wasn’t limited to one part of the test image.. When the white cross was introduced. nearby color patches became lighter and less saturated on the RGB LED TV. and colors from other rows also appeared to bleed toward the cross and the adjacent boxes.. Skin-tone sensitivity is part of the reason such artifacts stand out; when color backgrounds were placed behind a face image in the demo. the skin hue moved toward the surrounding color.
Insight: This is less about “bad color” and more about how edge behavior and local dimming interact with the human eye’s expectations, which can make certain transitions feel natural on one technology and distracting on another.
Beyond what the eye can catch during patterns, the demo also referenced color coverage behavior under BT.2020-style measurements.. According to Misryoum’s report. BT.2020 coverage decreased on the RGB LED TV when the color patches got smaller. with the most noticeable shifts tied to blue and green color points.. The mini-LED set with super quantum dots. by comparison. did not show color crosstalk in the same way during the test.
The difference may also come down to how fine the backlight control can be.. Misryoum’s account notes that the mini-LED approach can use a much higher number of dimming zones. while an RGB backlight needs separate red. green. and blue elements within each zone.. Finer control generally helps reduce spillover. and that showed up in the demo’s contrast impressions. particularly during darker scenes and fast-moving content.
Insight: Even if these effects can be subtle in solo viewing, side-by-side comparisons at controlled settings make the underlying limitations more visible, which can influence how buyers evaluate “spec sheet” color claims.
While the takeaway is not that every RGB LED TV will behave identically. Misryoum’s demo makes the concern clear for the current generation.. As vendors refine processing and backlight designs. the issue may shrink over time. but for now the contrast between RGB LED backlights and super quantum dot-based mini-LED was hard to miss in the testing setup.
