A text on the reasons why Samsung has to do quantum dot TV

QLED technology is transitioning from its early "green" phase to a more mature stage. Looking back at the evolution of the TV industry, from the competition between rear-projection and plasma TVs, to the current battle between QLED and OLED, every shift in display technology has led to a major reshuffling of the market. QLED, though introduced two years after OLED, is now gaining momentum, thanks to the efforts of major manufacturers like Samsung, TCL, Hisense, and Philips. In 2015, Samsung launched its SUHD TV, marking the beginning of the QLED era. The following year, it acquired QD Vision, the company known as the "father of quantum dot display," to further advance QLED development. In 2017, Samsung released its first QLED flagship model, the Q8C, officially entering the QLED market. TCL, another key player, was among the first to explore and promote quantum dot technology. Since launching its first product with quantum dot technology in 2014, TCL has been deeply committed to this field. From the world's first QUHD TV, the X1, in 2016, to the recently announced X5, TCL’s QLED lineup continues to grow rapidly. Hisense has also taken a different approach by developing its own ULED technology, incorporating quantum dot features into its high-quality LCD TVs. The Tianyi series represents a significant step forward in liquid crystal display innovation. According to reports, Hisense plans to launch new quantum dot display products in 2019, continuing to enhance its ULED offerings. Today, QLED technology is gradually maturing, with increasing market share and support from leading companies like Samsung and TCL. But what makes QLED so appealing? Let’s dive deeper. QLED stands for Quantum Dot Light Emitting Diode. It’s a type of display technology that sits between traditional LCD and OLED. The core idea is using blue LEDs to excite quantum dots, which then emit red and green light, resulting in a brighter, more vibrant image. These tiny semiconductor particles, ranging from 2 to 8 nanometers in size, emit different colors based on their diameter. This property allows them to produce a wide range of hues. In current QLED TVs, quantum dots are placed between the backlight and the LCD panel, forming a quantum dot film. This helps improve color accuracy and brightness while reducing energy consumption. By replacing traditional polarizers, it also lowers manufacturing costs. However, most QLED TVs today still rely on backlighting, making them more accurately described as QD-LCDs rather than fully self-illuminating displays. The ultimate goal for QLED is to achieve electroluminescence—similar to OLED—where the quantum dots themselves generate light without needing a backlight. Samsung is already working on this next-generation technology, aiming to eliminate the need for blue LEDs altogether. This would result in a display structure almost identical to OLED, but with different light-emitting materials. Despite being in an early development stage, QLED shows great promise. It offers higher brightness, better color performance, and lower power consumption compared to traditional LCDs. With continued advancements, it could eventually replace conventional LCDs entirely. While challenges remain, the future of display technology remains uncertain. Companies like LG and BOE are pushing OLED forward, while Samsung and TCL focus on electroluminescent QLED. As the industry stands at a crossroads, each company is choosing its path, much like the past battles between plasma and LCD. Ultimately, whether it's OLED or QLED, the real question for consumers is not just about the technology itself, but about who can deliver better performance at a lower cost. The competition is far from over, and the next few years will be crucial in shaping the future of television.
