Introduction to RGB LED Technology In the May 29, 2025 episode of Home Theater Geeks, host Scott Wilkinson delves into the cutting-edge RGB LED technology unveiled at CES 2025. This new advancement in LED TV technology promises to challenge the dominance of OLED displays by introducing a more versatile and vibrant lighting system.

Technical Overview of RGB LED vs. Existing Technologies Scott begins by clarifying that RGB LED TVs are essentially LCD TVs enhanced with RGB (Red, Green, Blue) LED backlights, specifically utilizing mini LEDs. Unlike traditional backlights that use solely blue LEDs, RGB LED backlights incorporate red, green, and blue LEDs, allowing each LED to emit full-color light, which can be finely controlled to produce a broad spectrum of colors.

“Instead of blue LEDs in the background, it uses red, green, and blue LEDs in each mini LED, making each one full color and fully controllable,” [01:35].

He contrasts this with the conventional QLED structure, which relies on blue mini LEDs combined with a quantum dot enhancement film to produce white light. This traditional method results in a lower-resolution black and white image in the backlight layer, which then passes through color filters to create the final image.

Advantages of RGB LED Technology The RGB LED setup offers several significant advantages:

• Increased Brightness: Hisense showcased a prototype reaching 10,000 nits of brightness, far surpassing the current maximum of 4,000 nits in standard consumer content.
• Reduced Blooming: Enhanced control over individual LEDs minimizes the bleeding of bright images against dark backgrounds.
• Wider Color Gamut and Increased Color Volume: Hisense claims the technology achieves 97% of BT 2020 and boasts the largest color volume compared to existing technologies like W OLED and QD OLED, ensuring colors remain saturated across a broader range of brightness levels.

“Hisense claims 97% of BT 2020 and a larger color volume, which means colors remain saturated over a greater range of brightness levels,” [04:15].

Additionally, the RGB LED backlights provide a superior color spectrum, particularly in the red and green ranges, contributing to richer and more vibrant colors.

Sony's Implementation and Prototype Reviews Scott updates listeners on Sony's involvement, noting that Sony demonstrated the RGB LED technology at their Tokyo headquarters. Although Scott wasn't part of the exclusive journalist trip, reports from attendees, including Ryan Juaniata of Wired, have been overwhelmingly positive. The Sony prototype reportedly outperforms the Bravia 9 and even the Bravia 8 OLED in color richness and brightness.

“According to Ryan Juaniata at Wired, the prototype had richer and more saturated colors than the Bravia 9... and it was clearly brighter,” [06:50].

However, there are caveats. While the RGB LED technology excels in brightness and color volume, Sony noted that black levels do not yet match those of OLED displays, a typical limitation of LCD-based technologies.

Comparison to OLED and QD OLED Scott provides a comprehensive comparison between RGB LED, OLED, and QD OLED technologies:

• Brightness: RGB LED TVs significantly outperform OLEDs, offering much higher brightness levels.
• Color Volume: RGB LED holds the highest color volume, surpassing both QD OLED and traditional Mini LED LCD TVs.
• Off-Axis Performance: Surprisingly, Sony's prototypes exhibit commendable off-axis performance, a common weakness in LCD-based TVs, although Scott remains cautiously optimistic pending personal reviews.
• Black Levels: OLEDs still maintain superior black levels compared to RGB LED, a critical factor for many viewers.

“It might give OLED some real competition… It’s likely to be very expensive, maybe more than OLED, which is already more expensive than any type of LCD TV,” [07:50].

Release Details and Market Potential The Hisense 116-inch UX Trichroma RGB TV is slated for release in 2025, while Sony anticipates bringing RGB LED TVs to the market by 2026. Scott speculates that the high costs associated with RGB LED technology could be a barrier initially, possibly rendering these TVs more expensive than their OLED counterparts.

Conclusion Scott concludes that RGB LED technology represents an exciting development in the TV industry, offering substantial improvements in brightness and color capabilities. While there are still questions regarding off-axis performance and pricing, RGB LED TVs are poised to introduce significant competition to existing OLED and QD OLED displays. Scott encourages enthusiasts to stay tuned for further reviews as the technology becomes more widely available.

“It's a very interesting technology and I wanted to share it with you as a sort of a preview of things to come. Not a dull moment in the TV industry, that's for sure,” [09:15].
