Image distortion corrected on curved windshields

Epson has developed and ramped-up production of the catchily-named S2D13V40, its first controller-integrated chip that's specifically designed for heads-up displays. It plans to produce 100,000 of the new controllers per month.

It's aiming to enhance safety and lessen fatigue, vehicle manufacturers have increasingly sought to install head-up displays that can be read with minimal eye movement. Although demand is expected to expand, manufacturers have faced issues such as system cost and development time.

Epson's new controller enables rapid HUD system development by offering the ability to correct the distortion of images streamed from a single SoC (system on a chip). The controller is equipped with display safety functions and supports the building of more reliable display systems. This controller IC satisfies the strict quality requirements of the automotive industry. It is compliant with the AEC-Q100 automotive specification and operates at temperatures up to 105°C.
