海外TECH	Engadget	What are Micro RGB TVs and why are they everywhere at CES 2026?	https://www.engadget.com/home/home-theater/what-are-micro-rgb-tvs-and-why-are-they-everywhere-at-ces-2026-182441543.html?src=rss	Micro RGB TVs first arrived last year with little fanfare and a confusing name so you may have mistaken it for other panel tech or not even noticed That is not likely to be the case this year though ーit s the hot new luxury display technology and is all over the place at CES So why do we even need these new TVs and how are they different from OLED Micro LED and Mini LED models Here s how it works and how it compares A brief history of flat panel display techTo better understand Micro RGB it helps to see how flat panel display technology has evolved over the last years The first LCD TVs used liquid crystals that become transparent to light when voltage is applied letting a rear backlight shine through as a pixel Those pixels combine to create moving or still images with color created via an RGB filter layer placed in front The main problem is that LCD crystals let some light partially leak through so blacks are dark grey instead of pure black And for a backlight early LCD TVs used a white screen lit by dim and power hungry fluorescent lights which caused uneven light distribution And finally the RGB filter color layer reduced a panel s brightness The next step up then was to use LED backlights instead placed at first at the edges of the white screen and then later directly behind it the first TV with this tech was Sony s Qualia That added the benefits of higher brightness lower power consumption improved color balance and even light distribution It also allowed individual dimming zones that improve contrast by allowing near pure blacks in shadow areas of an image Samsung s Neo QLED K TV from CES SamsungQuantum dot QD technology came on the scene around with Sony s Triluminos televisions This type of LCD panel employs a semiconductor nanocrystal layer rather than an RGB filter layer that can produce pure monochromatic red green and blue light when struck with a blue backlight Unlike previous LCDs they offer higher brightness and color accuracy thanks to the purity narrowness of the base RGB colors The best known TVs using this tech are Samsung s QLED models The latest evolution of QD LED technology is Mini LED That combines the accuracy of quantum dot tech with hundreds or even thousands of LED dimming zones Those models offer high brightness and color accuracy along with good contrast but still don t deliver perfect blacks and can display blooming in scenes with bright points of light due to leakage into neighboring pixels Both of those problems were solved with OLED technology which first came on the market in with Sony s XEL model The panels are made using sheets coated with organic LEDs each paired with a transistor that can switch the LED on or off On regular OLED TVs OLED pixels are white and a filter layer generates colors much as with LED TVs However with QD OLEDs OLED pixels are blue and color is created via a quantum dot layer like LED QD displays The latest version of QD OLED featured on several new monitors at CES Samsung s th gen QD OLED uses an RGB stripe pattern to reduce color fringing on text This is the first and still the only widely commercialized TV tech that can switch its light source off on a pixel by pixel basis allowing perfect black levels and near infinite contrast However due to their organic nature OLED TVs suffer from a lack of brightness and the potential for burn in that can kill pixels There is another type of self illuminating tech called Micro LED Rather than organic it uses microscopic inorganic LEDs to form the individual pixel elements Those can also be turned on or off individually so they offer the same pure blacks and sky high contrast as OLED At the same time they re potentially brighter than OLED and don t suffer from burn in The tech is still prohibitively expensive to manufacture though so none have arrived to market other than Samsung s The Wall which costs a cool Micro RGBDevindra Hardawar for EngadgetBefore talking about Micro RGB let s look at color space and gamut both for HDR which uses the BT standard and SDR commonly associated with the REC standard REC is ideal for regular HD content like TV broadcasts and YouTube videos It can display a limited set of colors and brightness is generally capped at nits BT however is designed for high end HDR streaming and K or K content creation via Dolby Vision HDR or HDR It has a much wider color gamut meaning it can display a wider variety of colors and a bigger chunk of the visible color spectrum It s also designed for significantly higher brightness levels of nits or more To achieve the color accuracy required for BT TVs must have extremely accurate red green and blue pixels Up until last year the most color accurate TVs used quantum dot technology and achieved a maximum of around percent BT coverage some projectors can cover percent or more of the BT spectrum as they use RGB lasers to create colors That brings us to Micro RGB also known as RGB Mini LED the most advanced LED panel yet Unlike the uniform white or blue backlights found on Mini LED models it features individually controlled precise red green and blue LED backlights that shine through a liquid crystal layer It also offers more local dimming zones The net result is higher color accuracy and better contrast than regular Mini LED displays but with potentially greater brightness than OLED Since each pixel still can t be turned on and off like OLED or Micro LED though contrast falls short of those technologies WikipediaSo far there is one and only one Micro RGB TV on the market Samsung s inch K MRF model The color accuracy is impressive with percent coverage of the challenging BT HDR standard an industry first and huge leap over quantum dot tech That means it can produce billions of colors natively and display a higher percentage of them in the visible spectrum than any TV to date Samsung left out a few key specs like the local dimming zone count only saying that it has four times more than its similarly priced inch QF QLED model so likely around The company also failed to disclose the total brightness in nits but the figure should be impressive given the potential of Micro RGB We were gobsmacked with the MRF Micro RGB model in person Engadget editor Sam Rutherford said it produced stunningly rich and vivid colors that put Samsung s other top tier TVs to shame including the aforementioned QF It also came with an equally stunning price tag A couple of other manufacturers including HiSense have also released RGB Mini LED models similar to Samsung s Micro RGB but they differ slightly in that the RGB modules are larger than the ones found on Samsung s latest TVs Which companies will have Micro RGB tech at CES SamsungLuckily the number of Micro RGB TVs is about to dramatically increase Earlier this month Samsung announced a full lineup using the technology with and inch screen sizes saying they d set a new standard for premium home viewing Those sets will also offer percent BT HDR coverage under a new certification standard called Micro RGB Precision Color While certainly likely to carry more reasonable prices than the first model they ll probably still be Samsung s most expensive TVs when released later this year And on Sunday Samsung also revealed a inch Micro RGB prototype meant to showcase the technology Once again it blew us away partially just because of the huge size but also due to the incredible quot color accuracy and richness quot as Engadget editor Devindra Hardawar put it quot I couldn t help but notice how everyone just looked a bit stunned like the monkeys from seeing the monolith for the first time quot he added At the same time LG announced its first Micro RGB evo TV lineup in and inch models The company is also promising percent BT color gamut coverage and said the sets will have over a thousand local dimming zones for color control Not only that it said that its new TVs will deliver percent coverage in SDR modes as well both for Adobe RGB and the challenge P standard It was interesting to compare LG s Wallpaper and other OLED sets with the new Micro RGB tech with our editor Devindra again being amazed quot LG already announced its Micro RGB set a few weeks ago but that didn t prepare me for standing in front of the inch demo TV it brought to CES quot he said quot Throughout a variety of clips colors looked wonderfully rich and the overall texture of the images looked surprisingly life like quot This article originally appeared on Engadget at	2026-01-05 18:24:42
