We had a discussion a few days ago. Rtings, the portal specializing in screen tests had begun A big test with 100 different TV models they call “TV Accelerated Longevity Test”A test, the foundations of which we can find on this web page, and that promises a lot to talk about.

The goal is to perform this test over a period of time. two years with an expiration time of approx. 12,000 hours To check whether the televisions are working correctly and to check the deterioration that may occur on the panels, and especially oled.

Results will be updated every few months and beyond. already do two intensive tests Results started to be obtained that encouraged manufacturers to talk about this issue.

Samsung QD-OLED panel televisions started to show themselves in the first images published by Rtings regarding the test results. early burn symptomson the other hand, it’s something that’s already envisioned for testing purposes, if not perhaps with so few working hours. currently LG’s look solid on models with tested 2nd generation EX panel.

The fact is that the producers began to offer their views on the matter and held an interview in the What HiFi media. soomin changResponsible for LG Display and Nathan SheffieldThe head of TV and Audio at Samsung Europe, discussed this issue.

In the LG example, Chang pointed out that: OLED panels “more stable” Thanks to the use of a much more stable material in manufacturing, such as deuterium on the second generation EX panels released last year.

Sheffield, for her part, These are the QD-OLED panels of 2023 (second generation) increased their productivity:

Brightness levels have been increased, although we don’t always have to keep them running at their maximum. So you can experience the best picture quality without straining the TV. I think this would probably reduce the risks you’re implying.

These statements are in line with what the company announced at CES 2023 that QD-OLED panels will include what they call their own. “new OLED HyperEfficient EL material” QD-OLED will allow to improve the color brightness of each pixel in the emission layer and will be achieved Up to 25% more efficiency.

In fact, during the presentation in January, Samsung did show some slides highlighting the QD-OLED panels of 2023, although it was somewhat overlooked. they promised to be twice as resilient More likely to extinctions than the first generation sold in 2022.

With all this, we can draw two conclusions. First, the actual comparison in the resistance of OLED and QD-OLED technologies, Samsung second generation panels those with (2023 ones) second or third generation (this is the so-called META sold in 2023) by LG if we want to have a more reliable opinion about both organic systems.

Second, as the people responsible for the tests explained and we commented on at the time, intensive tests It maximizes the brightness of the panels many times over without going through all the compensating cycles that have to be done and provided by the manufacturers. They are not real indicators of the TV’s operation..

However, it will be a topic that we will follow with interest as it is the first public test of this genre and includes various technologies. OLED, QD-OLED and LCD-LED.
