GoKawiilRTINGS testing finds edge pixel decay in 14 of 16 LG Display WOLED TVs
A long-term durability test by RTINGS ran 16 WOLED TVs from 2020-2023 for 18,000 hours, roughly a decade of typical use, and found 14 developed what it calls 'edge rot'—dead pixels or dark clusters along the screen borders. The defect appeared independent of on-screen content, unlike burn-in, and affected older LG Display WBC panels more than newer WBE ones, while Samsung's three QD-OLED sets showed no dead pixels at all.
GoKawiil's interpretation of the reporting above, not reported fact.
RTINGS suggests the likely cause is moisture seeping through small flaws in the panel's protective seal, a theory it says came from discussions with industry experts rather than confirmed testing. LG told RTINGS only a small number of units would show this after prolonged heat or humidity exposure, indicating the companies may disagree on how widespread the issue really is. The results could affect buyer confidence in used WOLED TVs and have already led RTINGS to lower its Expected Reliability score for all WOLED models pending more data.
- 14 of 16 older LG Display WOLED TVs (2020-2023) showed edge pixel decay after 18,000 hours of testing.
- Newer WBE panels with deuterium fared somewhat better, but 5 of 6 still showed some damage.
- Samsung's QD-OLED TVs had no dead pixels, while RTINGS now docks WOLED reliability scores pending further testing.
LG C3 Series OLED TV — If you're worried about edge rot on older WOLED panels, the LG C3 uses newer panel generation improvements that RTINGS found less prone to this issue than the earlier CX and C1 models. It still delivers the vibrant OLED picture quality and deep blacks you want, with the added peace of mind that comes from a more recent manufacturing process.
