While Samsung has turned out to be dominant in employing OLED tech on mobile screens—even Apple employs its displays for iPhones—in TVs, the big brand in OLED is its rival, LG. The TVs by LG have thrilled testers with their capability of controlling light accurately since each pixel is self-enlightening, unlike the “QLED” supported quantum dot LCD technology that Samsung exclusively depends on, which still places LED backlights at the back of a filter.
That can alter shortly, though, as Samsung declared in October that it is spending $11 Billion by the end of 2025 to develop a factory capable of producing actual QLED TV displays that self-illuminate. It tried developing TVs with the tech previously this decade, such as the Super OLED 55-inch displays. But it opted out of additional development, stating burn-in is too much of an issue and claiming that the TVs might have a short lifetime.
Now, two researchers at Samsung, Dr. Yu-Ho Won and Dr. Eunjoo Jang, have posted a paper in Nature about latest quantum dot LED tech that depends on indium phosphide rather than toxic cadmium, and has a life span of almost 1 million hours. Their enhanced shell design seems to elevate efficiency by stopping energy leaks and oxidation.
For Samsung to make that huge spending in developing “QD-OLED” screens it must believe any problems are going to be solved shortly, it is just a matter of when we will really witness new TVs in the market.
On a related note, Roku rules TV streaming in the US, and TV makers have noticed this. The newest series of 4K televisions from Chinese firm Hisense, the R8F 4K, will have Roku features in-built and the firm pledges they will provide a convenient UX as well as a high-quality picture.
