Older WOLED TVs suffer from "edge rot" as test finds dead pixels in 14 of 16 sets
The findings come from RTINGS, whose accelerated longevity test kept each TV running until it hit 18,000 hours, or roughly a decade of use in a typical US home. Of the 16 WOLED sets from 2020 to 2023 in that group, 14 came out with what the outlet calls edge... Read Entire Article
Recent tests have revealed that some older OLED TVs may suffer from a problem known as "edge rot." This issue, which affects the edges of the screen, involves the appearance of dead pixels or dark clusters over time. RTINGS, a testing organization, conducted an accelerated longevity test on 16 WOLED sets from 2020 to 2023, and found that 14 of them exhibited signs of edge rot.
This condition is not related to the content being displayed, and therefore, watching varied content will not prevent it. RTINGS attributes this issue to potential flaws in the thin protective seal around each panel, which could allow moisture to seep in over time. Among the ten TVs using LG Display's earlier WBC panels, only the 2022 LG A2 escaped damage.
Buyers of older WOLED TVs, particularly those with CX or C1 models, should closely inspect the edges for any dark specks before purchasing. Newer LG Display WBE panels have shown slightly better resistance, with five out of six sets displaying some damage. QD-OLED TVs from Samsung Display, on the other hand, did not show any dead pixels.
LG stated that only a small number of OLEDs might exhibit this issue after prolonged exposure to harsh conditions, but their standard warranty in the US only covers five years and does not include labor costs after the first year.
