Edge-Lit LCD TV Durability Concerns Emerge in New Test

A recent investigation by consumer electronics testing site RTINGs has raised concerns about the long-term durability of edge-lit LCD-LED televisions, a popular choice among consumers for their slim profiles and aesthetic appeal. The study, which simulated approximately six years of use through 10,000 hours of extreme testing on dozens of TVs, revealed a troubling trend of uniformity issues in edge-lit models, particularly affecting Samsung and LG products. According to RTINGs' findings, 64% of edge-lit TVs tested exhibited noticeable uniformity problems, compared to only 20% of full array local dimming (FALD) and direct-lit models. The primary issues identified were warped reflector sheets, cracked light guide plates, and burnt-out LEDs, all exacerbated by extended use at maximum brightness settings. RTINGs attributed these problems to the concentrated heat generation in edge-lit designs, with some LEDs reaching temperatures as high as 253.4F (123C). While Samsung defended its use of edge-lit technology, citing 15 years of reliable implementation and rigorous testing procedures, and LG reported no difference in defect rates between edge-lit and other LCD TV designs, RTINGs' research suggests that consumers seeking more durable TVs may want to consider alternatives to edge-lit models.Read more of this story at Slashdot.
