Samsung Display Becomes Industry's First to Receive 'True Bright' Perceived Luminance Certification

UL Solutions evaluates 7 types including QD-OLED
OLED and QD-OLED appear 1.5 times brighter than LCDs
"Providing differentiated value with outstanding perceived luminance"

Samsung Display announced on April 23 that it has become the first in the industry to receive the 'True Bright' verification from the global applied safety science company UL Solutions for its outstanding perceived luminance (PCL).

In connection with this, a certificate awarding ceremony was held the previous day at Samsung Display Research (SDR) in Giheung. The ceremony was attended by Jaenam Yoon, Vice President and Head of the Small and Medium Business Marketing Team, and Sherry Hu, Vice President of UL Solutions CMIT.

True Bright is a system that quantifies the black luminance (the degree of darkness in black) and the resulting perceived luminance of a display, officially certifying products that demonstrate high performance. The certification is based on the perceived luminance measurement method adopted as a standard by the international Semiconductor Equipment and Materials International (SEMI). SEMI is an industry association with participation from over 2,500 semiconductor and display companies worldwide and is responsible for reviewing and establishing related international standards. UL Solutions introduced this system for the first time in the industry earlier this year.

Perceived luminance refers to the brightness of a display as experienced by the human eye. It is a new evaluation criterion based on the fact that brightness is perceived differently depending not only on the physical amount of light reflected by the panel but also on the contrast ratio. OLEDs have a contrast ratio of 1,000,000:1, which is more than 1,000 times higher than that of LCDs, meaning that the same image appears brighter on an OLED display.

UL Solutions evaluated 15 types of Samsung Display's OLED products for laptops, tablets, and automotive applications, as well as 7 types of QD-OLEDs for monitors and TVs. The results confirmed that, for the same perceived luminance value, Samsung's OLED and QD-OLED displays appear on average 1.5 times brighter than LCDs, leading to the certification. According to UL Solutions, Samsung Display's 300-nit OLED achieved the same perceived luminance value (279.37) as a 510-nit LCD, while a 500-nit QD-OLED achieved the same perceived luminance value (310.9) as a 767-nit LCD.

A Samsung Display representative stated, "As the performance of information and communication technology (IT) devices rapidly advances, achieving high luminance with relatively low power consumption has become critical. In particular, for IT and automotive displays, high luminance characteristics that affect outdoor visibility are extremely important. Samsung OLEDs can provide differentiated value to customers and consumers thanks to their superior perceived luminance characteristics compared to LCDs."
