High rez displays drive revenues for chip vendors

Smartphones, 4K TV and other applications with high-resolution displays are a growing trend for driver IC revenue stream

Annual revenue for driver integrated circuits (ICs) will peak at $6.8-billion in 2017, due mainly to the demand for higher resolution displays in smartphones and other applications. Smartphones boasting full high-definition (FHD) and 4K-resolution displays are on the rise, which is contributing significantly to the increase in driver IC revenue, according to IHS Inc.

“To increase revenues panel makers are trying to reduce the number of driver ICs in their displays,” says Tadashi Uno, senior analyst and researcher for IHS Technology. “One way is to use driver ICs with more pins. While in the past the most popular source driver had 720 pins in the past, the latest driver ICs have more than 1000 pins, which drives down the number of driver ICs needed for each display.”

Among the many types of display materials and components, the driver IC supply chain is unique, according to the IHS Display Driver IC Market Tracker. Most driver IC makers are ‘fabless’ companies – like TSMC and UMC – that contract out their production, rather than owning their own factories. Due to increased competition in the market, prices and profits for driver ICs dropped dramatically after 2007, which is why foundry makers have de-prioritized driver IC production.


“The lead time from order to delivery in the driver IC market is around three months,” Uno says. “This timeframe is quite long, compared to other materials and components; however, driver IC order delivery and pricing are not affected by the usual supply-and-demand forces.”
