Samsung Display said Wednesday it has become the first company in the industry to receive the prestigious certification for perceptual brightness validation from UL Solutions, a global safety science company.
The True Bright certification measures the black luminance and the perceptual contrast length of displays, using the measurement method adopted as a standard by Semiconductor Equipment and Materials International. The technique was introduced earlier this year by UL Solutions.
UL Solutions evaluated 15 Samsung Display products, including organic light-emitting diode displays for laptops, tablets and automotive applications, as well as seven models of quantum dot-OLED displays for monitors and TVs.
The results confirmed that Samsung’s OLED and QD-OLED displays appear, on average, 1.5 times brighter than liquid crystal displays when the perceived luminance value is the same.
According to UL Solutions, Samsung's 300-nit OLED display matches the perceived luminance of a 510-nit LCD, both achieving a value of 279.37. Similarly, Samsung's 500-nit QD-OLED display corresponds to the perceived luminance of a 767-nit LCD, with a value of 310.9.
Perceived luminance refers to the brightness that users experience visually, which is influenced not only by the physical amount of light emitted by the panel, but also by the contrast ratio.
OLED displays, with a contrast ratio of 1 million-to-1, appear over 1,000 times brighter than LCDs, making OLED displays appear brighter even when displaying the same image.
“As the performance of IT devices rapidly advances, achieving high brightness with relatively low power consumption is crucial. Especially for IT and automotive displays, high brightness characteristics that affect outdoor visibility are extremely important,” said a Samsung Display official.
“Samsung OLED displays provide differentiated value to both customers and consumers through superior perceived luminance compared to LCDs,” the official added.
