4K display market to approach $18B this year

In 2015, LCD panel makers are targeting 40 million 4K LCD TV panel shipments, which represent 17 per cent 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 this year. 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 such as Sharp and JDI have recently announced and exhibited 4K smartphone panels. 4K tablet displays, using oxide (IGZO) and low temperature poly-silicon (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 LCDs. Essentially they use two sub-pixels per white pixel, to offer a similar perceived resolution as conventional three-colour red-green-blue (RGB) displays.

"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."
