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."
