The 10,000-hour extreme test simulates the situation after 6 years of use, and the edge-lit backlit LCD TV exposes durability issues

According to news from this website on August 2, the evaluation agency RTINGs released a research report this week, carrying out more than 10,000 hours of extreme testing on more than 100 TVs and several monitors, simulating the conditions of these TVs and monitors after several years of use.

The agency said it has currently tested more than 10,000 hours, simulating the conditions of these TVs and displays after 6 years of use, which found a "clear and disturbing trend".

The agency stated that compared with other LCD TV designs such as direct-lit (DIRECT LIT) backlight or full array local dimming (FALD), LCD TVs using edge-lit (EDGE LIT) backlight are more likely to suffer from serious durability issues.

The agency tested 11 TVs with edge-type backlights, and after testing, 7 had obvious uniformity problems. Of the 7 TVs, 2 are from LG and 5 are Samsung TVs.

The agency admits that the sample size is a bit small, but judging from the test results, 64% of edge-lit backlit TVs have durability problems, while in direct-lit and full-array local dimming TVs, problems The ratio is 20%.

A brief introduction to edge-lit backlighting on this site:

In edge-lit backlighting, there is a row of LED emitters (usually is white), allowing light to pass through the entire back of the LCD panel in an even manner.

Advantages:

makes the LCD screen thinner. If you see a very thin panel, it's likely to have edge-lit backlighting.

The cost is lower as it uses fewer LEDs to cover a larger display area.

Disadvantages:

There may be some brightness uniformity issues, causing the edges of the screen to be bright and the middle to be dark.

Edge lit displays have some size limitations that make them unsuitable for large LCDs.

Limited ability to adjust backlight based on content to improve contrast and save power. No matter what content is displayed, the backlight is always on.
