LG Display's organic light-emitting diode (OLED) technology has received certification from a global testing organization for accurately reproducing the colors and brightness intended by content creators.
On June 22, LG Display announced that its large OLED products for monitors and TVs have become the first in the world to receive the 'color and brightness accuracy' certification from the global testing and certification agency Intertek.
This certification evaluates how accurately a display reproduces the colors and brightness intended by the creator in typical indoor viewing environments. Unlike previous assessments that focused on individual performance metrics like peak brightness or color gamut, this certification quantitatively measures the overall picture quality as experienced during actual content viewing.
Intertek applied various test patterns to both OLED and liquid crystal display (LCD) products to measure the degree of color and brightness variation at specific screen locations. The results showed that LG Display's OLED achieved 100% color accuracy, 100% brightness accuracy, and was free from color crosstalk. This means it maintained consistent colors and brightness regardless of content size or screen configuration, while delivering unique colors without interference from surrounding pixels.
In contrast, LCD products did not reach the 100% level in the same evaluation. Due to the structural characteristics of LCDs, which control backlighting in zones, brightness can decrease or color distortion can occur around bright objects in high dynamic range (HDR) content. Some premium LCD products based on RGB LED technology exhibited color changes in objects depending on background color variations.
These differences stem from the display's light-emitting structure. OLEDs operate on a self-emissive basis, where millions of pixels emit their own light. This pixel dimming technology allows for independent control of each pixel, effectively eliminating light bleed and color interference. In contrast, LCDs rely on backlight sources, which have limitations due to light diffusion into adjacent areas.
LG Display's OLED panels, with 100% color and brightness accuracy, are driven by pixel dimming technology that allows each pixel to emit light independently. This self-emissive method fundamentally prevents light bleed and color interference.
As a result, the display can accurately convey the colors and brightness intended by the creator, regardless of varying conditions such as bright or dark areas or small or large content. This advantage is expected to provide distinctive value to customers enjoying high dynamic range and high-quality OTT content on large screens.
LG Display aims to leverage this certification to quantitatively demonstrate the value of consumer experiences in everyday life, thereby seizing leadership in the global picture quality competition.
Lee Hyun-woo, head of LG Display's large business division, stated, "This certification objectively proves that OLED perfectly and accurately reproduces the color and brightness values that consumers need, as intended by the creator. We will continue to clearly communicate the premium picture quality value that only OLED can provide to global customers, further strengthening our market leadership."
