Display Interoperability Event

The Display WG convened an interoperability event with many MIPI Alliance members November 1-4.  Administered by the University of New Hampshire InterOperability Lab (UNH-IOL), and hosted by MIPI member Agilent Technologies in Santa Clara, CA., the tests helped participating vendors evaluate the functionality of products implementing MIPI's D-PHY, Display Serial Interface (DSI) and Display Command Set (DCS) specifications.

Supporting organized testing in a neutral environment, the UNH-IOL test suite defined procedures for performing interoperability testing between compatible devices including host processors, display panels, and bridges that implement DSI over one or more D-PHY data lanes. The suite tests robustness of the physical link at a range of data rates, and transmits video sequences and bit-rate test patterns in a variety of image formats, resolutions, and frame rates to exercise higher layers of functionality.
 

Successful completion of the tests does not guarantee that the member's device will successfully operate with all other DSI products. However, when combined with satisfactory levels of interoperability testing, these tests provide a reasonable level of confidence that a Device Under Test (DUT) will function properly in different environments.

Stay tuned to hear more about this and future testing events, and progress in MIPI display interoperability.
 

The Display Working Group's mission is to:

• Develop open industry-standard interfaces between processor and display(s) in handheld systems
• Maximize commonality across multiple high-speed interfaces without compromising display-to-interface objectives
• Enable evolution of displays and display interfaces
• Accommodate a variety of architectures and system partitioning

The MIPI Alliance has published extensive support of both parallel and serial interfaces to mobile terminal displays. Both display specifications support a common command set to simplify software driver development. The serial interface, Display Serial interface (DSI) is highly scalable from one to four lanes and supports up to 12-bit/color offering brilliant, realistic color rendering for the most demanding imagery and video scenes.

Display WG has released a full set of test and interoperability documentation in cooperation from our membership test partners.

The group is aware of the tremendous excitement about 3D displays. Look forward to new announcements from us in the near future about fast-tracked developments standardizing future display interfaces for mobile terminals.
