DMCU - Display Module Controlling System
The client’s requirement was to drive various types of latest high end mobile displays to validate and verify them for the use in harsh environments. The one solution was needed to control displays for the technology demonstration purposes and automated display validation.
As the solution for mobile display quality validation system, DA-Design developed the Display Module Controlling System, which can easily be programmed and configured according to continuously evolving standards and specifications.
The DMCU system provides high level of flexibility that allows it to be configured for a wide range of different display module types with various resolutions, color depths, command sets, electrical interfaces and mechanical connectors.
The DMCU system comprises of hardware and PC software that is used for controlling of handset display modules independently of any actual handset and for analyzing display interface signaling. The usage of the system ranges from low-level electrical testing of display module to high level demo usage.
The significant advantage of the Display Module Controlling System is its fast and flexible configuration according to the newest standards and specifications. Therefore, the integrated system enables the verification and testing of controlled units not only within the extreme limits of operating environments, but also outside the standard boundaries.
