LG Display is further expanding its OLED TV panel market leadership based on its expertise in OLED technology, which the company has built for over a decade. Earlier this year, LG Display demonstrated its continued large-sized OLED innovation by unveiling its latest OLED TV panel technology, fourth-generation OLED. With global interest soaring as soon as this new tech was introduced, let’s take a closer look at some of the reactions from around the world.
The pinnacle of high-definition display: LG Display’s 4th-gen OLED
To briefly explain first though, LG Display’s fourth-generation OLED TV panel centers on a Primary RGB Tandem structure, which is the company’s proprietary technology. It organizes the light source into four stacks by adding two layers of blue elements and independent layers of red and green elements. With an extra layer compared with the previous three stack light source, the panel produces more light and raises maximum brightness by 33%.
As a result, fourth-generation OLED achieves a brightness level of up to 4,000 nits (1 nit is the brightness produced by a candle), which is the highest among OLED TV panels. Color brightness has also increased by 40% compared to the previous generation’s 1,500 nits, reaching 2,100 nits. At the same time, by enhancing the panel’s structure and power supply system, LG Display has improved its energy efficiency by around 20% (based on a 65-inch panel).
Moreover, unlike general displays that are significantly impacted by external light, LG Display’s fourth-generation OLED TV panel features a special film that offsets both light reflected from the display’s surface and light absorbed and reflected inside the panel. The company’s ultra-low reflection technology allows its fourth-generation OLED TV panel to block 99% of reflections, realizing perfect black just like in a movie theater with the lights off even in a midday living room setting (an ambient brightness level of 500 lux) as well as 100% color accuracy and virtually no change in color gamut. In addition, it provides differentiated customer value through human-friendly technologies, such as by emitting only half the amount of blue light as a typical LCD screen and improving the recycling rate of end-of-life product parts to over 92.7%.
“One of the biggest TV developments” –Techradar
In response to the new panel, British tech media outlet TechRadar stated, “One of the biggest TV developments at CES 2025 was a new fourth-generation ‘four-stack’ OLED panel developed by LG Display.” Raising expectations for the future, the article added that “the prospect of OLED TVs with higher brightness, which LG Display considers ‘a key picture quality factor because it enables more vivid images that are akin to natural human vision,’ is enticing.”
American tech media outlet Digital Trends was also full of praise. “The amount of improved brightness is the truly impressive part,” the article insisted. Referring to one of the new TV models featuring a fourth-generation OLED panel, the article said it “was honestly supremely impressive, and very well might be the best TV we see in 2025.”
“Time to get off last year’s hype” –What Hi-Fi
Another British tech media publication, What Hi-Fi, urged readers to upgrade their view of OLED: “If you’re still riding last year’s micro-lens array (MLA) hype train, it’s time to get off at the next stop – this new four-layer panel tech looks set to replace it, with higher brightness levels in the process.” Also, American media outlet Forbes picked a product equipped with fourth-generation OLED as one of its “Glamorous TVs of CES 2025.” It explained that it “features a new four-stack OLED panel that appears significantly brighter than the micro-lens-array technology used in previous (generations).”
LG Display plans to consolidate its dominance in the premium TV market by gradually applying fourth-generation OLED TV panels to its top-of-the-line mass-produced lineup this year. 55% of the company’s sales last year were OLED products, as it pursues a strategy of advancing its OLED-centered business structure. Keep an eye on LG Display’s OLED technology innovation as it continues in the future!
