Micro RGB Micro RGB LED backlight (Samsung Micro RGB, LG Micro RGB evo)

What Micro RGB is

Micro RGB is a backlight architecture. Behind a normal LCD panel sits an array of red, green and blue LEDs that Samsung says are each less than 100 µm (0.1 mm) across and individually controlled. The colors are mixed at the backlight, so the panel no longer needs a white or blue source converted through quantum-dot and color-filter layers. Expert Reviews describes the R95H as lighting the picture with separate red, green and blue LEDs rather than white or blue backlights passed through color filters. Samsung's launch covered two 2026 series, the R95H flagship and the R85H, in sizes from 55 to 115 inches.

LG sells the same idea as Micro RGB evo (model MRGB95B, 75, 86 and 100 inches). LG's US product page calls it "an LCD TV" with dedicated red, green and blue backlights. Both brands position it as a step beyond conventional Mini LED, and Expert Reviews lists the R95H panel as "Micro RGB (Mini LED) with local dimming." Treat the names as branding for one family of RGB-backlit LCDs. The existing RGB Mini LED backlight entry covers the Hisense and Sony versions of the architecture.

How Micro RGB works

Each zone of the backlight can shift both brightness and color. LG says its Micro Dimming Ultra manages "more than a thousand dimming zones." Samsung has not published a zone count in the launch material I read, but Expert Reviews lists 1,792 zones on the 75-inch R95H. A 75-inch 16:9 panel has about 2,404 square inches of area, so 1,792 zones works out to roughly 1.34 square inches per zone, or a square about 1.16 inches (29 mm) on a side. The 3,840 x 2,160 panel has 8,294,400 pixels, so each zone covers around 4,600 pixels.

Color is where the marketing is loudest. Samsung states 100% coverage of BT.2020, verified by VDE under a "Micro RGB Precision Colour" certification. LG cites Intertek certification of 100% coverage in BT.2020, DCI-P3 and Adobe RGB. BT.2020 is the wide-gamut container defined in ITU-R BT.2020-2 (10/2015). In eCoustics' measurements of a 65-inch R95H in Filmmaker Mode, BT.2020 coverage came in at 93.3%, 6.7 points below the claim.

Brightness is not claimed in Samsung's newsroom text. Measurements fill the gap: eCoustics logged 2,039 nits at a 10% window and 642 nits full-screen in Filmmaker Mode on the 65-inch R95H, and 1,908 nits and 790 nits in Standard mode. Expert Reviews measured 2,200 cd/m² on a 10% window on the 75-inch. The 10% peak is 3.2 times the full-screen figure, which shows how much the power budget favors small highlights.

Micro RGB vs RGB Mini LED vs Micro LED

Micro RGB and RGB Mini LED share the same optical idea. The sources I loaded give Samsung's under-100 µm figure but no micron size for Hisense's or LG's LEDs, so any claim that one brand's LEDs are smaller than another's is unverified here. LG says only that its Micro RGB uses its smallest individual RGB LEDs.

Micro RGB is not Micro LED display technology. A Micro LED display makes every pixel its own emitter and has no LCD layer. A Micro RGB set has about 1,800 zones lighting 8.3 million LCD pixels, so a small bright object can still bloom. Expert Reviews notes that any blooming takes on the color of the bright object, and eCoustics saw very minimal blooming on high-contrast test images. Against OLED, Ubergizmo's verdict is that OLED remains the more obvious choice for black levels and dark-room contrast, while Micro RGB wins on color purity and peak brightness. Because the emitters are inorganic LEDs, the burn-in risk of OLED does not apply the same way. See Mini LED vs OLED for the room-lighting tradeoff.

Which TVs use it

Samsung R95H: 4K, 165 Hz Motion Xcelerator and HDR10+ ADVANCED. Samsung's launch release also lists Micro RGB Colour Booster Pro and a Glare Free feature that reduces reflections. US launch prices were $3,199.99 (65 inch), $4,499.99 (75 inch) and $6,499.99 (85 inch); eCoustics lists the current MSRP as $2,999.99, $4,299.99 and $5,999.99. Samsung R85H: 144 Hz and launch prices of $1,599.99 (55 inch), $2,099.99 (65 inch), $2,799.99 (75 inch) and $3,999.99 (85 inch). Both series have four HDMI 2.1 ports. Measured game-mode input lag on the R95H was 10.7 ms at eCoustics and 10.4 ms at Expert Reviews.

LG MRGB95B: the 86-inch lists at $5,299.99 on LG's US site. It uses the α11 AI Processor Gen3, supports VRR up to 165 Hz, and lists Dolby Vision and Filmmaker Mode. LG's page gives no peak brightness or zone count, so the "more than a thousand zones" press line is the only official number.

Common confusions

"Micro" refers to the LED size, not to a Micro LED panel. "100% BT.2020" is a certified claim, and a reviewer's colorimeter measures lower. Zone counts and peak brightness differ by screen size, picture mode and test window, so compare the 10% and full-screen figures separately before judging a set against OLED. Samsung's R95H and R85H also support HDR10+ Advanced, which affects what you can stream rather than how the backlight behaves. SVC adds that both Samsung series ship with Dolby Atmos, Eclipsa Audio and a matte screen coating, and Ubergizmo reports 165 Hz on the R95H against 144 Hz on the R85H, and lists a 115-inch MR95F at $29,999.99.
