MIPI Alliance and VESA to Specify Data Compression Schemes for Mobile Display Apps

MIPI Alliance and the Video Electronics Standards Association (VESA) have announced a collaborative liaison to specify data compression schemes for mobile display applications.

VESA is an international, not-for-profit standards association, representing a global network of hardware, software, personal computer, display and component manufacturers committed to developing and promoting the electronics industry, while MIPI Alliance is a collaborative organization, consisting of companies that span the mobile ecosystem, which aims to define and promote interface specifications for mobile devices.

The collaborative liaison calls on these two groups to determine the cost-effective compression proposals. In addition, they are also expected to evaluate techniques that deliver visually lossless compression and also reduce display interface bandwidth.

At the time of deploying high-resolution mobile panels, the compression schemes will continue to lower system power as well as cost, according to the officials of the organizations.

The organization has joined VESA in an effort to improve display interface technology, said Joel Huloux, chairman of the Board of MIPI Alliance, adding that higher resolution, lower power and lower cost for mobile displays are key areas for mobile, personal computer and consumer electronics manufacturers.

Huloux expects that the joint discussions will generate new approaches that enable a deterioration-free image quality.

MIPI Alliance provides a comprehensive portfolio of display interface specifications that targets communication between the mobile applications processors and the display peripherals. These specifications are highly scalable from one to four lanes. Moreover for demanding imagery and video scenes, they support up to12-bit/color.

VESA has developed over 50 display and display interface standards, including DisplayPor, a high-bandwidth video interface. "Extensions to the DisplayPort standard such as eDP, have allowed DisplayPort to become a diverse standard adapting to new form factors," said Bill Lempesis, executive director at VESA.

He believes that the joint venture with MIPI will allow for continued collaboration toward improving data compression schemes for mobile display applications.

Recently, The University of New Hampshire Interoperability Laboratory (UNH-IOL (News - Alert)), an independent provider of broad-based testing and standards conformance services for the networking industry, announced that it is demonstrating its MIPI testing services for mobile device components suppliers at Mobile World Congress (News - Alert) 2013 in Barcelona, Spain.
