RTINGS Identifies Edge Degradation in Majority of Tested WOLED Televisions
After 18,000 hours of testing, damage was found in 14 out of 16 televisions with WOLED panels from LG Display.
RTINGS specialists have discovered a defect known as Edge Rot in the majority of tested WOLED televisions. This defect manifests as dead pixels and clusters of dead pixels along the edges of the screen. Researchers suggest that the cause may be damage to the panel's protective layers or manufacturing defects.
Devices with older WBC panels were the most affected, with signs of degradation appearing in nine out of ten models. Among televisions with newer WBE panels, damage was found in five out of six.
Meanwhile, three tested models with QD-OLED panels from Samsung Display completed the tests without similar defects. However, the sample size is too small to consider this technology completely immune.
LG has acknowledged the existence of the problem and attributed it to prolonged exposure to high temperature and humidity. However, RTINGS has not yet determined the exact cause of the damage or whether it affects panels produced since 2024. Therefore, the results do not allow for conclusions about the durability of all modern OLED televisions.
