Bosch Wins CES Best Innovation Award for Virtual Visitor LCD from Crawforddefine's blog

Engineering is applying scientific concepts to produce technology that answers real problems. At CES 2020 in Las Vegas, Bosch shows how engineering works. Bosch receives a CES Best of Innovation award for a virtual visor addressing the real issue of early morning or late driving into the sun.

Safely driving requires visibility. While the light normally illuminates our world, it can be too much depending on the time of day. Anyone driving has faced the difficulty of adjusting a sun visor to shield the sun from glaring directly in their eyes while still providing the road ahead. Bosch engineer Ryan Todd used to go from his home in Ann Arbor, Mich. to the Bosch Technical Center in Plymouth, a route that corresponded with the morning and evening sunrise throughout the year.

As part of an internal innovation competition, Zink and his teammates sought a solution to the sun-blinding problem, while maximizing visibility. monochrome LCD display technology with camera-facing driver and computer controls.

They swiftly prototyped a system using the display panel from a retired laptop for proof of concept and made numerous revisions for a workable prototype. The liquid crystal displays used in many modern gadgets, including computers, telephones and televisions, are effectively a grid of individually programmable shutters. What we generally perceive comes from light from behind the display. Energizing a shutter blocks light, whereas deenergizing brings light through.

This technique is employed for the window shades on the Boeing 787, which allows passengers to alter the opacity of an overlaying LCD on the window from transparent to virtually opaque. Using a camera, the Bosch technical team detects the driver's face and where they gaze. A monochrome LCD pattern replaces the visor.
