QLED VS OLED in the TV market
The ongoing technical battle between OLED and QLED has reached a fever pitch, with both technologies vying to become the dominant display solution for future TVs. This competition has drawn in numerous TV manufacturers, each eager to lead the next generation of visual innovation.
For over four years, traditional TV brands have managed to stay relevant, while some internet-based TV companies have struggled due to rising panel prices. Beyond sales battles, the war over display technology is also a major spectacle in the industry. The rivalry between OLED and QLED has become a daily topic among consumers and experts alike.
As quality consumption rises, so does the demand for better TV experiences. This has intensified the debate between OLED and QLED, two technologies that are shaping the future of television displays. With more manufacturers entering the race, the competition is heating up fast.
On one side, companies like LG and Skyworth are pushing hard on OLED technology, making it more accessible to consumers. In 2016, only five global manufacturers produced OLED TVs, but by 2017, that number had grown to 13, including several Chinese brands. On the other hand, Samsung and TCL are promoting QLED technology. According to NPD DisplaySearch, the Chinese market for QLED TVs is expected to grow by 100% annually, jumping from 600,000 units in 2016 to 1.2 million in 2017.
Fan Zhijun, general manager of Suning Shanghai, noted that technological debates have always been part of the TV industry’s evolution. From early disputes over rear projection versus large-screen technology, to the decline of plasma TVs as LCDs improved, the industry has seen many shifts. Now, in the post-LCD era, the question is whether OLED or QLED will take the lead.
Samsung recently launched a new marketing campaign targeting OLED, claiming it's not suitable for TVs due to issues like screen burn-in. Instead, they promote their own QLED technology. Samsung argues that OLED panels, which use organic materials, are prone to degradation over time, making them unsuitable for long-lasting devices like TVs. In contrast, QLED uses semiconductor nanocrystals, which are more durable and better suited for television use.
OLED TVs also face challenges such as limited supply and high costs. Ross Young from DSCC once predicted that QLED could dominate the next-gen TV market, citing OLED's inability to meet demand and its pricing issues.
LG didn't directly respond to Samsung's claims but emphasized that OLED TVs are the top choice in 11 countries, showing strong consumer appeal.
What is quantum dot technology?
QLED TVs use quantum dots—artificial nanocrystals with semiconductor properties—that enhance brightness and color performance on LCD screens. These tiny particles emit light when struck by photons, with the color depending on the size of the quantum dots. Larger dots emit red, smaller ones emit green, and a mix can produce the full color spectrum needed for TV viewing. By leveraging these properties, manufacturers can significantly improve the color accuracy and brightness of LCD TVs.
