MIPI Display Serial Interface (DSI / DSI-2) Test Solutions

The MIPI Alliance offers two specifications for implementing mobile displays: the Display Serial Interface (DSI℠) and the Display Serial Interface 2 (DSI-2℠). These specifications enable the creation of very high resolution displays while using exceptionally power-efficient physical layers. For this reason, MIPI DSI and DSI-2 based displays have become the devices of choice for high-end smart phone manufacturers, and they are also increasingly used in non-mobile applications such as infotainment systems or wearables.

Modern DSI and DSI-2 implementations include advanced innovations, such as compression, spread-spectrum clocking, and Bus Turnaround (BTA), which give rise to substantial design and validation challenges. Fortunately, Introspect Technology has created the most complete suite of test tools for display driver integrated circuits (DDICs) as well as completely assembled display panels, ranging from protocol exercising and analysis to high-volume production testing and system-level emulation.
