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

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 threestack 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 humanfriendly 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."

They've continued to push WOLED past my expectations TBH. I thought brightness/heat would continue to be much more of a limiting factor without the use of increasingly enormous heatsinks etc, but it seems like they basically figured that out last gen and intend to go even further. I still view WOLED as a consumable good like brake pads or tires on a car, but if they can also continue to push prices down I hope it remains an option on the market for the future. I dont know if I would want to have a WOLED display on all-in-one hardware that needs to last at least a decade (maybe like a high end audio receiver or something.) For something standalone like a monitor or value/middle tier tv I am willing to take on the degradation factor. After all, brands are still putting out LED monitors where the internals fail before 5 years anyway.

I have their 2020 LG CX one (4K/120Hz), still no burn-in, bright enough, fast enough...can't even imagine what 2025 LG will be 5 years after.

VERY happy with mine, I'll upgrade when my tv dies or micro-led is mainstream and affordable or 8K is mainstream and affordable, whichever comes first, so really not in a hurry

For my gaming monitor I went with QD-OLED tho, upgraded after 8 years and also very happy with it, I think if they can add more brightness to OLED gaming monitors it'll be perfect but frankly it's already VERY beautiful

It uses AI to adjust the picture in any environment? Does it change it on the fly or just when you turn it on? Seems like marketing garbage to me...

I guess no-one picked up on the fact that a version of this will comet to gaming monitors at some point soon-ish as well?

I have a C8 that I've been using as a PC monitor since 2019, so I have some burn-in from browser and taskbar icons (and some HUD elements from playing Destiny 2 for almost 3000 hours :D ). But it's not very noticeable in regular content, mainly on single-color areas like sky and stuff.

My entire setup is limited to 4K60, so I would need to replace the TV, the A/V receiver and the capture card to benefit from 4K120, therefore I'm not in a rush.

With HDMI 2.2 coming soon, I wonder when we'll see 4K240 TVs and receivers. It hope the transition goes smoother than the HDMI 2.1 fiasco in 2020.

It is but QD-OLED had a similar improvement and that's my preference. The new EL 3.0 (electroluminescent layer) materials in the stack that help improve efficiency by more than 30%, resulting in no increase to power consumption over the 2023 panel and no additional heat generation.

This is without even adding blue PHOLED. In 2026, switching to PHOLED for blue could lead to a 25% reduction in power consumption.

It's going to take many years for HDMI 2.2 to be implemented. 2027-2028 for commercial usage. Might be longer for residential.

I use my TV for apple TV and PS5 mainly, you are not the first one to experience burn-in using it as a monitor. For me it was too big as a monitor, max was 32" for me.

Reason why naturally gaming monitors from LG and Samsung are dimmer and have beefier heatsinks etc.

They keep pushing this brighter and brighter and i keep lowering and lowering the brightness. Just don't need to be blind any time soon.

I assumed as much but thought it would show up next year when they introduce it later to the C series like usual. Does this mean C5 will be MLA+?
Displays are moving really fast and if they keep the gaming monitors up to speed with the G series of TVs then that's great news.
