I’ve seen Sony’s impressive new mini-LED TV backlight tech in action, and OLED TVs should be worried


Sony made a special occasion of its 2024 TV launch, holding it at the Sony Pictures Studios lot in Los Angeles. At the event, attendees, myself included, were treated to demos of Foley effects and soundtrack mixing, plus other striking examples of behind-the-scenes movie magic that happens at the studio. Sony’s message was that the technology that goes into movie and TV creation via its studio and professional camera and display divisions trickles down into consumer products, and it was made loud and clear at the event.

The Sony Bravia 9 is the flagship model of the new Bravia series TVs, taking that crown from the Sony A95L OLED TV, which will continue in the lineup for 2024. Interestingly, the Bravia 9 is a mini-LED TV. That marks a change in direction for Sony, a brand that in the past had regularly positioned OLED as the most premium technology in its TV lineup.

Sony’s re-positioning of mini-LED at the top of the TV food chain results from two tech developments at the company. The first is the creation of the BVM-HX3110, a professional mastering monitor capable of 4,000 nits peak brightness. The BVM-HX3110 was introduced in late 2023, and replaces the BVM-HX310, a standard model for movie post-production that tops out at 1,000 nits peak brightness.

The second development is XR Backlight Master Drive with High Peak Luminance, a new TV backlight technology used exclusively in the Sony Bravia 9 mini-LED TV. According to Sony, its next-gen backlight tech is responsible for a 50% brightness boost in the Bravia 9 over the company’s previous flagship mini-LED model, the Sony X95L, along with a 325% increase in local dimming zones – something it accomplishes through a new, highly miniaturized 22-bit LED driver.
