The Heated Windshield Problem

A heated windshield product has been developed which closely matches ideal criteria for this product. The many elements of the system are balanced to realize clearing performance, low reflection, high transmission, a good visual impression, and manufacturability at low cost. The core of the development is a coat-flat-and-bend approach in the thin film technology. The approach to this development, attributes of the process, and properties of the final product are described.
