Lu: DisplayPort is targeted at the PC market, but it is also applicable to CE applications.

Parade Technologies Ltd is making bets on DisplayPort as the new video interface for high-resolution display devices. The analog and mixed-signal fabless company, which has a design house in Shanghai, China, has taken a proactive part in the spec definition.

Calling itself an early bird in this new standard domain, Parade sees DisplayPort as a serious opportunity, given the right engineering resources. The company has expertise in areas like high-speed interface and video graphics and processing.

DisplayPort proponents like Parade claim the technology can grow and scale to high-end applications. "Being a packet-based architecture, it can be tailored for different configurations," said Ding Lu, VP of product development at Parade. "It can occupy a single lane for smaller displays, while it can offer four lanes for higher-size displays."

DVI face-off
According to Lu, DVI is mostly suited to PC video, while HDMI is a DVI-like technology with audio and secondary data to make it adaptable to consumer electronics applications.

"DVI has speed limitations and this could be a factor for high-resolution displays," Lu added. "DisplayPort is targeted at the PC market, but it is also applicable to CE applications."

However, Lu acknowledged that HDMI has a stronghold in the CE and TV markets, and that it is likely to stay in the lead.

DisplayPort, according to Lu, has a technology edge in its low power consumption and lower cost, and this is bound to be a differentiating factor as more and more users move from a desktop PC to a notebook, driving the need for power reduction.

2008: Year of DisplayPort
Parade is currently seeking strategic alliances with PC companies as it expects DisplayPort to take off this year.

DisplayPort spec was released in 2006 and activities like interoperability tests began last year. Lu said that it is now a mature spec with the 1.1a revision.

Parade sees DisplayPort as a mid- to long-term opportunity and the company is confident of its chances to become the new video interface. "Big names usually move slowly to new opportunities like DisplayPort," Lu said.

The firm is well connected with design houses in mainland China, and Lu said this has helped in providing analog and mixed-signal expertise.

The company also offers a complete line of HDMI switch products like repeaters and level shifters.
