Santa Clara, Calif. — Strong promotion of Ultra HD 4K TVs, rising 4K panel yield rates, and the emergence of 4K displays this year in desktop monitors, notebook PCs, digital signage and mobile devices will boost factory-level 4K panel revenues by 94 percent this year to $18 billion, an IHS report contended.
With the evolution of new manufacturing technologies to enhance the 4K display yield rate and reduce costs, IHS forecast 4K display revenues will hit $52 billion in 2020.
In 2014, revenues hit $9.2 billion in 2014, with 4K LCD TV contributing $8.8 billion to overall revenue,
but smartphones and OLED TVs will experience the strongest growth in 2015, IHS said. OLED TV makers are also adopting 4K resolutions.
With fine-pitch pixel designs and improved brightness transmittance, 4K displays will become more affordable for mobile devices, the company said. Panel makers like Sharp and JDI have already announced and exhibited 4K smartphone panels. Tablet 4K displays using oxide (IGZO) and low-temperature poly-silicon (LTPS) processes are also in panel makers’ plans, the company said.
To date, LCD TV makers have driven 4K LCD panel growth, strongly promoting 4K TVs to enhance value, but 4K content and broadcasting availability is also on the rise, further spurring 4K TV growth, IHS said. Meantime, “LCD TV panel makers have continuously improved 4K panel yield, which has reduced costs and facilitated even more consumer adoption,” said David Hsieh, display research senior director for IHS.
In 2015, LCD panel makers are targeting 40 million 4K LCD TV panel shipments, accounting for 17 percent of all LCD TV panel shipments.
TVs with 4K resolution, combined with the “TV everywhere” concept, raise consumer desire for higher resolution screens in their mobile devices, the company said.
Another important element in boosting 4K TV sales is sub-pixel rendering (SPR), which “will become an important way for panel makers to enhance 4K pixel design in their displays,” IHS said. “For many years, various versions of SPR have been used in the commercial production of AMOLED and LCD 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.”
SPR essentially uses two sub-pixels per white pixel to offer a similar perceived resolution as conventional three-color RGB displays, the company explained.
