"Since its market introduction in 2013, TV brands have recognized that 4K is a great way to enhance value, so they have strongly promoted 4K models," said David Hsieh, senior director of display research for IHS. "4K content and broadcasting availability is also on the rise, which is helping more TV buyers recognize the value of this feature. Meanwhile, LCD TV panel makers have continuously improved 4K panel yields, which have reduced costs and facilitated even more consumer adoption."
In 2015, LCD panel makers are targeting 40 million 4K LCD TV panel shipments, which represent 17% of all LCD TV panel shipments. In addition to TVs, consumers are starting to enjoy the benefits of ultra-high-resolution content in their smartphones and other mobile devices. Meanwhile, the "TV everywhere" concept is increasing consumer desire for higher resolution screens in their mobile devices. The professional-monitor and public-display market are also increasingly adopting 4K displays.
4K LCD TVs continue to be the largest segment of the 4K display market, but smartphones and OLED TVs will experience the strongest growth in 2015, said IHS. In order to compete with LCD TV in the high-end segment, OLED TV makers are including 4K resolutions. As display technology is improving fine-pitch pixel designs and brightness transmittance, 4K displays will become more affordable for mobile devices. In fact, panel makers like Sharp and JDI have recently announced and exhibited 4K smartphone panels. 4K tablet displays, using oxide (IGZO) and LTPS processes, are also in panel makers' plans.
On the other hand, sub-pixel rendering (SPR) technology will become an important way for panel makers to enhance 4K pixel design in their displays. For many years now, various versions of SPR have been used in the commercial production of AMOLED and LCD displays. Essentially they use two sub-pixels per white pixel, to offer a similar perceived resolution as conventional three-color red-green-blue (RGB) displays, the firm added.
"The main benefits of SPR include fewer sub-pixels, higher transmission and lower power consumption," Hsieh said. "SPR is an important element in the growth of the 4K display market."
