LG, MRGB87 TV's Truth About Fake Mini RGB Backlighting
The mini RGB technology featured in LG's new MRGB87 series (originally called MRGB85 at CES 2026) unveiled at CES 2026 generated tremendous excitement.
However, even then, we had already publicly expressed at least a bewildered skepticism about the mini RGB backlight system implemented in LG's MRGB87 televisions using the edge LED method.
In reality, it goes one step further. This backlight system does not take advantage of the benefits of independent RGB diodes at all and has been found to operate like a typical LCD screen.
The fact that it is an edge LED backlight consisting of RGB LED triplets is already disappointing enough, but there are two other facts that are still difficult to accept.
Disassembling a 2026 LG mini RGB TV revealed two things: first, there is only one diode bar at the bottom of the screen. Second, there is no need to find any controller that controls the RGB diodes (one red, one green, and one blue coated with phosphor).
White Light Generation Using Limited RGB Diodes
As a result, each RGB LED triplet emits light at the same intensity from all three color diodes, and it is impossible to control them by adjusting the brightness of one diode compared to others or turning one diode on while keeping the others off.
Therefore, the three RGB diodes create white light, which then passes through RGB color filters. In summary, LG's mini RGB display (MRGB87 series for the French launch model) operates exactly the same way as a typical LCD TV using additive mixing.
The claim that "colors are generated from the backlight light source itself," which is a differentiating factor of mini LED RGB technology, becomes invalid here, and the use of RGB diodes ultimately proves to be useless.
Pure Marketing Claim to Ride the Trend
Then a question arises: why complicate things when it could be done simply? The answer likely lies in the marketing nature of utilizing the commercial logic of "mini RGB."
Indeed, thanks to this complex backlight structure, LG was able to attach and utilize the trending term "mini RGB" to this screen following CES 2025 and Highsense's related announcements.
Legally, there is no problem since RGB diodes actually exist. However, I will leave the rest of the judgment to you.
