Pixelworks announced its latest Iris family mobile display processor, the PX8468 which is based on the company’s patented DNX technology originally used in high-end TVs, Pixelworks’ third generation mobile chip, PX8468, combines the technology, called True View, that enables displays to adapt automatically based on the ambient light and color temperature, as well as support for mobile HDR (High-Dynamic Range).

Advantages of Iris:

  • 500 million pixel operations per second
  • Optimal viewing under any ambient light condition
  • 10-bit processing pipeline with auto-adaptive lighting, colour and contrast
  • Motion Estimation, Motion Compensation (MEMC) claims industry-leading blur reduction and judder-free video
  • High-Dynamic Range (HDR) for superior color accuracy and sharper detail

Richard Miller, Pixelworks’ GM & Executive Vice President of Technology said, “Our True View feature set leverages auto-adaptive technology to enable a highly optimised viewing experience indoors or outdoors, and offers mobile OEMs much-needed differentiation at the lowest power and smallest footprint available. Additionally, by using Iris, mobile OEMs can qualify their devices for the highest picture quality standards required by providers of HDR content.”

“Our ZenPad and ZenFone product lines have benefited from Pixelworks’ Iris family of display processors,” said Rangoon Chang, Asus General Manager, Mobile Computing Business Unit. “Being able to deliver a high-end TV experience for premium content on a mobile device is a key differentiator for Asus, and we look forward to continuing this partnership with Pixelworks to further differentiate our future mobile devices.”

Dr. Raymond Soneira, President of DisplayMate Technologies Corporation, commented, “DisplayMate has been a pioneer in advocating better display performance in ambient light as a key requirement for the next-generation of displays. With their new Iris processor, Pixelworks is providing important new technology and tools that will allow device manufacturers to significantly improve their display’s on-screen color and contrast image quality for consumers in real world ambient light viewing conditions.”

Pixelworks’ PX8468, the latest generation in the Company’s Iris family of mobile chips, is 20% smaller and consumes 25% lower power than the previous generation Iris device. It is sampling and available for mass production today in a small 4.25 x 4.80-mm WL-CSP package

Analyst Comment

The performance of displays in bright ambient is a continuing issue and so we welcome any technology that helps to improve it. It’s unusual to see Ray Soneira, the visual quality maven, endorsing a chip for its processing. If Ray says that it works, then we’re prepared to believe it does! (BR)
