LG Display Unveils Fourth-Generation OLED Panel with AI Optimization and Enhanced Brightness

LG's next-gen OLED panels promise 4,000 nits brightness and better burn-in resistance

Serving tech enthusiasts for over 25 years. TechSpot means tech analysis and advice you can trust. LG plans to launch its brightest-ever OLED screen later this year. A new internal structure enables the fourth-gen panel to achieve a maximum brightness of 4,000 nits - about 30 percent higher than the previous generation. The new display also boosts color brightness by 40 percent, increasing from 1,500 to 2,100 nits. These improvements are attributed to LG's updated primary RGB tandem structure, which has evolved from three to four stacks, sandwiching two layers of blue pixels between layers of red and green pixels. Last year, the company proposed using the tandem system to increase resistance to burn-in - one of the primary drawbacks of OLED panels. The technology combines fluorescence and phosphorescent elements to increase blue light efficiency, which is the main cause of burn-in. In addition, LG's fourth-gen panel also aims to address another issue common to OLED screens - reflections in bright rooms. The company claims that its new special film blocks 99 percent of light reflected from and within the display's surface. LG said the primary use case for the brightness and energy efficiency improvements is - wait for it - AI. Similar to how PC hardware manufacturers recently began promoting AI PCs that run GenAI workloads locally, TV companies like LG and Samsung are trying to sell the concept of "AI TVs." An AI customization page on LG's website reads like the industry discovered a new buzzword to convince consumers to upgrade their TVs again. The company is promoting AI as the next stage in the evolution of smart TVs. AI-powered features include acoustic tuning and brightness control, which analyze a user's room to adjust sound and brightness automatically. Additionally, AI director processing optimizes color distribution, while super resolution technology upscales images to 8K while preserving film grain. Other AI features include a "picture wizard" to assist users in navigating settings and a chatbot to provide troubleshooting support. Needless to say, these all sound like a bunch of nothingburger features, but I digress. LG has yet to disclose shipping dates for their latest OLED panels, but they are expected to appear in flagship TVs sometime this year, followed by OLED gaming monitors. Although the need for AI features remains unproven, the newly announced quality and reliability improvements might contribute to OLED's already growing market share. At CES, LG said that 22 percent of PC gaming monitors are OLED compared to just 18 percent of TVs. Samsung has also seen a surge in OLED sales and is preparing models capable of reaching 500Hz refresh rates, but high prices remain the biggest obstacle to wide adoption.

LG Display Unveils 4th-Generation OLED Panel Optimized for AI Era

SEOUL, South Korea, Jan. 15, 2025 /PRNewswire/ -- LG Display, the world's leading innovator of display technologies, continues to lead the way in large-sized OLED technology by unveiling its fourth-generation OLED TV panel. 33% brighter than the previous generation and optimized for the AI TV era, it is the industry's first-ever OLED display to achieve a maximum brightness as high as 4,000 nits (1 nit is the brightness produced by a candle). Panels with both high brightness and energy efficiency are essential for AI TVs, as they use upscaling that analyzes content in real time to deliver ultra-high picture quality of up to 8K. The industry also considers higher brightness to be a key picture quality factor because it enables more vivid images that are akin to natural human vision. LG Display's fourth-generation OLED TV panel meets the performance demands of the most advanced AI TVs, interacting in real-time with the TV's on-device AI to deliver the perfect picture in any environment. The new panel's innovation centers on a Primary RGB Tandem structure, which is LG Display's proprietary technology that uses independent stacks of RGB elements to produce light. It had previously used a three-stack light source, with two layers of blue elements emitting relatively short energy wavelengths alongside red, green, and yellow elements in a single layer. The Primary RGB Tandem structure applied to the fourth-generation OLED TV panel organizes the light source into four stacks by adding two layers of blue elements and independent layers of red and green elements. It improves maximum brightness by increasing the amount of light produced by each layer compared to the previous structure. As well as increasing maximum brightness, LG Display has raised the latest OLED panel generation's color brightness. Color purity is enhanced by separating the red, green, and blue elements - the three primary colors of light - into distinct layers, resulting in a color brightness of 2,100 nits, a 40% improvement over the previous generation (1,500 nits). In addition, energy efficiency has been maximized in line with the significantly higher expected power consumption of AI TVs. By enhancing the fourth-generation OLED TV panel's structure and power supply system, LG Display has reduced its temperature and achieved around 20% greater energy efficiency than the previous generation (in the case of a 65-inch panel). It also delivers a customer experience that pushes the limits of display with stunning picture quality featuring perfect blacks and rich colors in any environment. In general, a display's color reproduction is affected by external light. As the screen reflects ambient light in a bright room, black may appear gray or overlapping reflections of nearby objects might disrupt the viewing experience. For example, while watching content featuring a night sky in a living room in the middle of the day, any sense of immersion would be broken if the sky appears foggy or if reflected furniture overlaps on the screen. To solve this customer inconvenience, LG Display has developed a special film that offsets both light reflected from the display's surface and light absorbed and reflected inside the panel. With the advantage of this ultra-low reflection technology, the company's fourth-generation OLED TV panel blocks 99% of internal and external light reflections, realizing perfect black just like in a movie theater with the lights off even in a midday living room setting (500 lux). A display's color gamut and accuracy also decrease dramatically as the viewing environment gets brighter. However, this TV panel sees virtually no change in color gamut and offers 100% color accuracy at 500 lux. It is therefore the only display to overcome the viewing environment limitations of conventional displays. Meanwhile, the fourth-generation OLED TV panel provides differentiated customer value through human-friendly technologies, such as by emitting only 45% blue light compared with the 70-80% level that would typically be produced by an LCD screen. Blue light is known to negatively affect users' vision and circadian rhythms. It additionally stands out as a sustainable display by adopting eco-friendly methods in the entire product life cycle from development to mass production, including using more than 90% fewer plastic raw materials than LCDs and improving the recycling rate of end-of-life product parts to over 92.7%. LG Display will apply its fourth-generation OLED TV panel to its top-of-the-line mass-produced lineup this year to consolidate its dominance in the premium TV market. The company then plans to gradually apply its Primary RGB Tandem technology to its Gaming OLED lineup, targeting the high-end gaming market with a diverse range of panels. This already includes the world's fastest monitor panel equipped with the industry's highest response speed and refresh rate, which are important specifications for gaming monitors, as well as bendable panels that adjust their curvature according to the gaming content. "The fourth-generation OLED panel is the essence of innovation that exceeds the limits of existing displays by applying LG Display's unique technologies such as Primary RGB Tandem and ultra-low reflection technology," said Hyeon-woo Lee, Senior Vice President and Head of the Large Display Business Unit at LG Display. He added, "We will provide an unprecedented customer experience along with superior picture quality and user-friendly technology while strengthening our OLED technology leadership."
