Physical and cost analysis of the instrument cluster and infotainment display module available in the latest Mercedes A-Class Style Line.

In-car infotainment raises expectations from designers and drivers, and demand is growing year by year. Amidst this, LG Display is selling a complete infotainment cluster including two displays – one handset, and one touchscreen. The first vehicle that we find this cluster in is the Mercedes A-Class.

LG has strong knowledge of automotive displays. Of its latest product’s  two displays, one shows driving functions, like engine status and navigation maps. The other is a touchscreen allowing users to control infotainment parameters. The displays include an ambient light sensor, enabling adaptive contrast and lighting intensity inside the car. This cluster may be easily adapted to the interior vehicle style of each car manufacturer.

This report presents a complete teardown analysis of LG’s display and the associated touchscreen extracted from the A-Class Mercedes. Based on this, it provides the bill-of-material (BOM) and manufacturing cost of the cluster display. The report also offers a complete physical analysis and manufacturing cost estimate for every part, including the backlight module and the different mechanical frames.
