Abstract:
A windshield display system for installation into a vehicle that includes a windshield, a transparent display overlaying the windshield, and an array of electrowetting lenses overlaying the transparent display. Each lens of the array is operable to a flat-state where light passes through the lens substantially undistorted, and a shaped-state where emitted light from an underlying portion of the transparent display is directed in order to increase an apparent brightness of the emitted light. The array selectively magnifies pixels or portions of the transparent display, while maintaining vision clarity for the operator in regions of the windshield where images are not being displayed. The array may also outline or highlight images being displayed with a region of distortion of surrounding the image to distort the view of the scene outside the vehicle to help the operator discern the image when the outside lighting conditions are less than ideal.
