- Nanosys staged a side‑by‑side demo at Display Week of an 85‑inch TCL X11L TV with super quantum dot (SQD) backlight and an 85‑inch TCL RM9L TV with RGB LED backlight, both in Filmmaker Mode with native color settings.
- RGB LED TV showed color crosstalk and a drop in BT.2020 gamut coverage, especially for blue and green, when a white‑cross overlay was displayed, while the SQD TV showed none.
- SQD TV delivered higher contrast and a larger dimming‑zone count (14,400 zones per Rtings) versus roughly 8,000 zones on the RGB LED TV, because its blue‑LED backlight lets each LED act as a zone.
- Industry experts have warned of color‑crosstalk issues in RGB LED TVs since CES 2025, and LG Display released videos weeks before this year’s CES highlighting the problem.
- Author verified that the crosstalk altered skin‑tone hue in test images, even when focusing on a small facial area with a scope, confirming the effect was a display artifact.
- Nanosys asserts that super quantum dot technology holds the performance edge in 2026, though the author notes that some RGB LED models (e.g., Hisense UR9) may mitigate crosstalk through processing or fallback to white backlight.
Why it matters: Consumers and manufacturers of high‑end TVs gain a clear performance benchmark: SQD panels deliver superior color accuracy and contrast, while RGB LED panels risk visual artifacts that can degrade viewing experience, pressuring OEMs to refine backlight designs or invest in new technologies.
