✅ [SAIBA AGORA] Quais TV’s DURAM MENOS | Por que estão QUEIMANDO?

Summary

In this video, the presenter explores the longevity of different TV technologies, focusing on the results of a comprehensive test conducted by rtings.com. Over 10,000 hours of testing were done on various TV models, revealing that Edge LED (Ed LED) TVs are more prone to early failure due to excessive heat buildup, while Direct LED (DLED) models proved to be more durable. The video provides insights into how backlighting technologies impact TV performance, helping consumers make informed decisions when choosing a TV for long-term use.

Takeaways

• 😀 The video discusses the durability of different TV models, focusing on LED and Edge LED technologies.
• 😀 The tests were based on over 10,000 hours of use, equivalent to approximately 7 years of usage for a typical household TV.
• 😀 Edge LED TVs were found to overheat significantly, causing quicker degradation, with some showing issues after only 1,500 hours of use (about a year).
• 😀 64% of Edge LED TVs tested experienced problems with uneven brightness or display issues.
• 😀 Full Array LED (Del LED) TVs, on the other hand, showed more even heat distribution, leading to fewer issues and better longevity.
• 😀 The study excluded OLED models due to the risk of burn-in, which affected their inclusion in the durability tests.
• 😀 The primary issue with Edge LED TVs is their higher temperature in the edges, leading to faster breakdowns.
• 😀 TVs with Full Array LED technology showed a much slower onset of defects, with only 20% experiencing any issues.
• 😀 Manufacturers like Samsung and LG responded by stating that they continuously improve thermal management in their Edge LED models.
• 😀 Despite improvements, the research suggests Full Array LED TVs are the better choice for those seeking long-term durability and performance.
• 😀 The video encourages viewers to consider their TV's technology type when looking for a model that will last longer and avoid rapid failure.

Q & A

What was the main purpose of the rtings.com study?

The main purpose of the rtings.com study was to test the durability and longevity of various TV models, specifically focusing on the differences between Direct LED (D-LED) and Edge LED (E-LED) technologies.

Which TV technologies were tested in the rtings.com study?

The study tested two main types of TV retroillumination technologies: Direct LED (D-LED) and Edge LED (E-LED), which are commonly used in modern TVs.

How were the TVs tested in the study?

The TVs were kept on continuously with the brightness set to maximum for over 10,000 hours (about 7 years of domestic usage), to see which technology would fail first.

What were the key findings of the study regarding temperature?

The study found that E-LED TVs reached much higher temperatures, with the edges reaching up to 123°C, compared to D-LED TVs, which had more even heat distribution and lower overall temperatures.

Which type of TV (D-LED or E-LED) had more durability issues?

E-LED TVs were more prone to durability issues, with 64% of them showing problems such as uneven brightness within approximately one year of use, whereas only 20% of D-LED TVs had similar issues.

What kind of defects were observed in the E-LED TVs during the tests?

E-LED TVs showed defects such as uneven brightness (with some areas much brighter than others), screen warping, cracks, and physical damage due to excessive heat at the edges.

How did the manufacturers respond to the study's findings?

Samsung acknowledged ongoing improvements to their E-LED models' thermal management but admitted that high temperatures remained an issue. LG, on the other hand, stated that they had not observed significant differences in defect rates between D-LED and E-LED TVs, though this claim was met with skepticism.

What was the overall conclusion of the study?

The overall conclusion was that D-LED TVs tend to last longer and are more reliable due to their more even heat distribution, whereas E-LED TVs degrade faster due to excessive heat buildup at the edges.

Why is Edge LED used in some TV models despite the potential for quicker failure?

Edge LED technology is used in some TV models because it allows for thinner TVs, making them more attractive to consumers, despite the potential for quicker failure due to heat buildup.

What are some signs that a TV might have E-LED technology?

Signs that a TV might have E-LED technology include a thinner design, as the LEDs are positioned along the edges rather than behind the screen, which is a characteristic of E-LED TVs like the Samsung Frame and Crystal models.
