5 terms

color gamut technical

"display quality had largely been assessed based on specifications such as color gamut or peak luminance"

Color gamut is the range of colors a display or imaging system can produce, like the palette of paints an artist can choose from. A wider gamut means richer, more accurate colors that make screens, photos and videos look closer to real life. Investors care because gamut affects product quality and differentiation, influences consumer preference and pricing, and can impact manufacturing costs, supply-chain choices and competitive positioning in device and content markets.

peak luminance technical

"assessed based on specifications such as color gamut or peak luminance, which have limitations"

Peak luminance is the maximum brightness a screen, light source, or imaging device can produce, typically measured in nits. Think of it as how bright a flashlight can get at full power; higher peak luminance makes images look clearer in bright environments, supports premium display features, and can influence energy use and heat. Investors care because it affects product competitiveness, perceived quality, regulatory compliance for safety/medical imaging, and potential market pricing and margins.

hdr technical

"limitations when displaying high dynamic range (HDR) content such as starry night skies"

High-dose-rate (HDR) refers to a form of localized radiation therapy that delivers a strong, concentrated beam of radiation to a targeted spot for a short time, often using a temporary implant placed close to a tumor. Investors care because HDR treatments can offer faster procedures, shorter hospital stays and potentially better targeting than traditional options, which can affect adoption of related devices, treatment volumes, reimbursement and therefore a healthcare company's revenue prospects.

color crosstalk technical

"even premium LCD panels exhibit color crosstalk and reduced accuracy in brightness"

Color crosstalk is when a camera sensor or display lets light or signal meant for one color channel spill into others, so colors appear washed, mixed, or inaccurate. For investors, it matters because it reduces product image quality and sensor accuracy, can trigger redesigns or recalls, affect customer satisfaction, and influence manufacturing costs and competitive positioning—much like paint bleeding between sections ruins a finished picture.

pixel dimming technical

"LG Display's OLED panels operate using pixel dimming technology, with millions of individual pixels"

Pixel dimming is a display technique where individual pixels or small groups of pixels are made darker through software or hardware control to reduce power use or improve perceived contrast, similar to dimming a lamp in one corner of a room rather than the whole room. For investors, it matters because it affects device battery life, image quality, manufacturing complexity and component demand, which in turn influence product competitiveness, returns and costs across the supply chain.

SEOUL, South Korea, June 21, 2026 /PRNewswire/ -- LG Display, the world's leading innovator of display technologies, announced today that its entire lineup of large-sized OLED panels, including for monitors and TVs, has become the first in the world to receive "Perfect Color/Brightness Accuracy up to 500 lux" certification from global testing and certification organization Intertek. This certification confirms that a display can accurately reproduce both color and brightness regardless of viewing conditions or content.

The certification is particularly meaningful as it quantitatively validates how accurately a display reproduces color and brightness. Previously, display quality had largely been assessed based on specifications such as color gamut or peak luminance, which have limitations in objectively verifying how closely a display reproduces real-world colors.

To address this, Intertek conducted comprehensive testing on OLED and LCD displays using a range of test patterns to measure variations in color and brightness, thereby objectively evaluating overall picture quality accuracy.

The test results revealed that LG Display's OLED panels — featuring self-emissive pixels — simultaneously recorded 100% color accuracy, 100% brightness accuracy, and color crosstalk-free performance. Therefore, they deliver the creator's intended color and brightness accurately, whatever the viewing environment or type of content. 100% color accuracy means consistent color reproduction regardless of test pattern size; 100% brightness accuracy refers to uniform brightness regardless of test pattern size; color crosstalk-free performance means no color interference between adjacent pixels, enabling precise color expression.

In contrast, LCD displays — which rely on backlight units larger than individual pixels — showed limitations when displaying high dynamic range (HDR) content such as starry night skies or fireworks, where brightness in highlighted areas can be diminished. In some premium LCD TVs using RGB LED backlights, color distortion was observed depending on the background colors.

These differences in picture quality accuracy stem from fundamental differences in light emission methods.

LCD-based displays control light by zones through a backlight, leading to light leakage into adjacent areas. This structural limitation means that even premium LCD panels exhibit color crosstalk and reduced accuracy in brightness and color reproduction.

LG Display's OLED panels operate using pixel dimming technology, with millions of individual pixels emitting light independently. This self-emissive structure fundamentally eliminates light leakage and interference, enabling precise reproduction of both bright and dark elements, regardless of content size or scene conditions, and delivering a superior viewing experience.

Through this certification, LG Display aims to take the lead in global picture quality competition by quantifying the value of real-world viewing experiences perceived by consumers.

"LG Display's OLED has now been objectively proven to deliver the most accurate color and brightness even in everyday viewing environments," said Hyeon-woo Lee, Head of the Large Display Business Unit at LG Display. "We will continue to strengthen our market leadership by more clearly communicating the differentiated value of premium picture quality that only OLED can deliver to customers worldwide."
