Quantum dot displays are used to boost the colors possible in ultra-HD TVs, using a mix of compounds to enrich the color gamut. Use of quantum dots has grown in the last several years as television manufacturers find them to be a low-cost and low-energy solution, and new research from Grand View Research Inc. shows that the market for quantum dot displays is expected to reach $3.96 billion by 2022.
The growth can be attributed to increased awareness and a strong demand for QLED TVs, as well as the proliferation of the technology. Quantum dot technology is also anticipated to see increased use in smartphones and tablets.
The majority of current quantum dot technology is used in the consumer electronics segment (70 percent), with healthcare also contributing to a significant degree as display technology is used in imaging, diagnosis, and other capacities. The North American market leads the quantum dot display industry, with 40 percent of the overall global revenue share.
According to the report, quantum dot-based LEDs accounted for more than 45 percent of the global quantum dot display industry’s market share in 2014. Samsung, Panasonic, LG, and Sharp are all working on ultra-HD TVs using QD-based LEDs. Other major players in this space are Dow Chemica, Nanoco Group, NAnosys, and Quantum Material Corporation.
Samsung’s use of quantum dot displays shows another trend in the market. Their switch from conventional OLED TVs to QD-based 4K TVs was caused in part by high development costs.
Binary compounds like cadmium selenide, cadmium sulfide, cadmium telluride, and indium arsenide are at the core of quantum dot displays. However, toxic chemicals like cadmium, lead, and mercury are limited in the amounts to which they are allowed to be used in consumer products. However, the environmental concerns presented by the use of cadmium resulted in the development of cadmium-free quantum dots (CFQD). Use of these CFQD technology is expected to increase as companies find that it allows them to use quantum dots in more consumer devices.
