Abstract
Abstract A head-up holographic display for providing a display on a vehicle windshield of a control panel and indications of the vehicle operator's manual movements and manual selection operations on the control panel. The display includes a number of edge-illuminatable hologram layers providing a background display and touch and activation indications. Signals from the control panel selectively illuminate respective layers and portions thereof in response to operations on the control panel to create a windshield display thereof. In a second embodiment, a head-up virtual image background display is provided by a first hologram and dots indicative of the driver's finger position on the control panel are positioned on the background display by selective illumination of a second hologram.
