Display Head Assembly

Display Head Assembly (DHA)

Scroll down

With highly vertically integrated display head assemblies (DHA) customized to each application we provide an integrated assembly with any feature the user interacts with from the display, keys, and encoders to touchscreens.

  • Integrated Man-Machine Display Interface

    Technically optimal and commercially simplified, DHA has rapidly been favored by the largest Tier 1 OEMs that seek high performance and cost-efficiency. We customize our DHAs for every application, and also inventory readily available subassemblies that can be integrated or re-engineered to satisfy specific requirements.

  • We Own What We Integrate

    DHAs are more efficiently designed when Cevians’ multidisciplinary team with expertise in all of the subcomponents collaborates to optimize each of the design features. Technical risks are greatly reduced when we, as a single design authority, ensure the highest accountability towards the final product’s performance. Cevians integrates its custom AMLCD and optical products in its DHA.

  • Unparalleled Efficiency

    Our unique capability of integrating all electro-mechanical components and man-machine interfaces with the various AMLCD elements provides significant technical, cost, and time to market efficiencies. In all cases, the resulting number of components in the integrated DHA is reduced, increasing reliability and reducing cost. Most design features perform much more than one role. For example, a light cavity wall can be eliminated and a structural wall in the MMI can take its place.
