To put it another way, these panels perfectly reproduce content at a level of visual quality typically found only in darkened movie theaters, even when they are placed in the brightest living room.
(PR) LG Display's 4th-Generation OLED Panel Obtains Industry's First Perfect Reproduction Verification
LG Display, the world's leading innovator of display technologies, announced today that its fourth-generation OLED panels have been verified by UL Solutions, a global leader in applied safety science, for Perfect Reproduction technology under lighting conditions of up to 500 lux, which is the brightness of a living room in broad daylight. This verification is for displays that most perfectly reproduce original content, including color and brightness, even in bright environments. It recognizes that LG Display's fourth-generation OLED panels accurately reproduce over 95% of original images, based on 4K video (approximately 8.3 million pixels).
