Samsung Display Recognized by International Certification Body for 'Hole Display' Performance

[Asia Economy Reporter Ki-min Lee] Samsung Display announced on the 26th that it has been recognized for excellent image quality performance in the 'Hole Area Clarity' category, which measures the uniformity of image quality around hole displays, by the global safety certification organization UL (Underwriters Laboratories).

UL recently verified the uniformity of image quality between the camera hole area and other parts of the hole display on the 120Hz high-speed organic light-emitting diode (OLED) used in the Galaxy Note20 Ultra and Galaxy Z Fold2, which were recently announced by Samsung Electronics. To do this, 12 points were designated around the hole area, and color, brightness, and saturation were measured at each point to compare the differences.

The verification results showed that the color deviation index of the 12 points around the hole area was evaluated to be below Delta E 2. Delta E indicates the difference in color, with lower values meaning less difference; values below 2 are generally difficult to distinguish with the naked eye. This signifies that Samsung Display’s hole display technology and performance are at the highest industry level.

Samsung Display named the hole display that passed the uniformity verification of image quality around the hole area the 'Iris Ring.' Samsung Electronics explained that this name was inspired by the fact that a healthy and beautiful eye is recognized when the iris and the white of the eye contrast clearly. In other words, it means a display where the black camera hole and the clear image quality around the hole form a perfect contrast.

Samsung Display introduced the 'Iris Ring' through high-performance laser processing and design technology. In fact, if the processing and design technology are insufficient, the area around the hole will show color differences compared to other parts of the display, resulting in degraded screen performance.

A Samsung Display official stated, "To provide users with an immersive full-screen experience, it is very important not only to have hole display technology but also to enhance the image quality performance around the hole area," adding, "Through this 'Hole Area Clarity' verification, we have proven that Samsung Display’s hole display technology is at the highest industry level."
