RTINGS 10-Year Equivalent TV Longevity Update With Many Casualties

For the past two-and-half years Canadian consumer testing outfit RTINGS has been running an accelerated aging experiment across a large number of TVs available to a North-American audience. In their most recent update, we not only find out about the latest casualties, but also the impending end of the experiment after 18,000 hours — as the TVs are currently failing left and right as they accelerate up the ascending ramp of the bathtub curve.

Some of these LEDs are dead, others are just wired in series. (Credit: RTINGS.com) — Some of these LEDs are dead, others are just wired in series.

The dumbest failure type has to be the TVs (such as the Sony X90J) where the failure of a single dead backlight LED causes the whole TV to stop working along with series-wired LED backlights where one dead LED takes out a whole strip or zone. Other failures include degrading lightguides much as with our last update coverage last year, which was when edge-lit TVs were keeling over due to overheating issues.

Detailed updates can be found on the constantly updating log for the experiment, such as on the failed quantum dot diffusor plate in a TCL QLED TV, as the quantum dots have degraded to the point of green being completely missing. Although some OLEDs are still among the ‘living’, they’re showing severe degradation – as pictured above – after what would be the equivalent of ten years of typical usage.

Once the experiment wraps up it will be fascinating to see who the survivors are, and what the chances are of still using that shiny new TV ten years from now.

Brewing Up Some Quantum Dots

October 12, 2011 by Mike Szczys 7 Comments

We’re taking a field trip from the backyard, garage, and basement hacking in order to look in on what research scientists are up to these days. A group from the Johns Hopkins Institute for NanoBioTechnology has been manufacturing quantum dots for use in the medical field. Made up of Cadmium Selenide, this is a nanomaterial that you can think of as individual crystals of the smallest size possible. Quantum dots have many uses. Here, [Charli Dvoracek] takes the recently manufactured dots and activates them with antibodies capable of targeting cancer cells. Once mixed with a biological sample, the dots embed themselves in the walls of the cancer, allowing the researchers to find those cells thanks to the phosphorescent properties of the dots.

The video after the breaks walks us through the various steps involved in growing these dots. [Charli] has the benefit of a fully outfitted lab, using tools like an argon-filled glove box to protect her from harmful off-gases. You’re not likely have this sort of thing in your home laboratory, but as we’ve seen before, you can make some of your own equipment, and produce interesting chemicals with simple processes. If you’re someone who already tinkers with chemistry experiments we want to hear about your exploits so please drop us a tip about what you’re up to.
