Samsung Display announced that its OLED displays for laptop applications has received 'Halo Free' verification from the safety science leader, UL, for its glare-free and sharp picture quality.

Samsung OLED halo-free (UL verification)

Samsung explains that LCD displays suffer from light-blurring which occurs when the outline of a bright subject appears white on an image with sharp contrast. This is because even with local dimming, LCDs cannot adjust the backlight brightness exactly on the edge. OLEDs, with their self-lit pixels, do not suffer from this.

Samsung says that according to its internal evaluations on 'light blurring degree (halation),' its self-luminous OLED showed a halation of 0.00% and no indication of light blurring. When a focus group was studied watching content on OLED display screens, no light blur was observed by Samsung Display, even when measured from both 45 degree and 60 degree viewing angles.
