At CES 2025, Hisense didn’t showcase many new products. While we usually get the full ULED range announcement during the show, the company is seemingly holding off on this for now. However, that doesn’t mean Hisense didn’t have anything cool to look at. The company showcased a new 116UX TV, a number of laser projectors, but most importantly, the TV maker debuted its game-changing new backlight tech called RGB Local Dimming Technology.
Essentially, RGB Local Dimming Technology is a new form of tech that replaces the existing backlights you find on Mini-LED TVs with RGB lights. Up to now, Mini-LED TVs use blue lights at the back of a panel that light up and pass brightness through a colour filter. This filter is basically what you see on your TV. The lights just bring the filter to life.
However, the limitation of blue lights means that the colour range on these TVs is limited. While TVs still look pretty decent (you can watch the best TV of 2024 in action here in my Hisense U8N TV review), one way to improve the colour is to replace the existing blue lights with red, blue, and green ones – RGB lights.
So instead of the basic blue lights creating light behind the colour filter on TVs, these RGB lights will be able to add accurate coloured lighting to the filter where needed. If the image is red, the lights can now turn red, and the TV won’t have to perform algorithms to clean up the “cool” tones caused by the blue lights.
Hisense says this is a big deal. By using the colour lights on the TV, panels will now be able to achieve 97% of the BT.2020 colour space. Not only does this result in richer, more accurate colours, but TVs will also have better control over the picture.
The perks continue. Hisense says RGB Local Dimming Technology TVs will also be able to produce brighter images due to less light having to pass through the colour filter. The TVs will also use 10% less power compared to non-RGB Local Dimming Technology TVs.
In addition to all that, it is also natural that these TVs will produce less harmful blue light because of the RGB backlights. Hisense says out-of-the-box, the TVs will produce 40% less harmful blue light before the user calibrates the panel.
Hisense hasn’t shared where the RGB Local Dimming Technology will be found outside of its 116-inch UX Mini-LED TV. This massive TV is expected to launch later in 2025 and will likely be the last thing on your shopping list given its size and price tag.
The company will debut its 2025 ULED lineup sometime in the months ahead, so we’ll have to see whether or not the tech is used in those TVs. At the moment, both the 116UX and the insane 136-inch Micro-LED TV will include the new lights. These TVs are branded as “Hisense TriChroma TVs”.
