Abstract
A transparent display screen can be positioned in a driver's line of sight or in front of mechanical indicators on an instrument panel. The display screen preferably has a frame or rim member along only one edge of the screen. Since the display screen is transparent and does not include a frame or rim around its perimeter, the display screen makes information available without obstructing the driver's view of the road. The single frame or rim member supports all of the row and column electrodes that are used to selectively illuminate the pixels on the display screen. The transparent display screen can be used effectively with one or more mechanical indicators positioned properly near the display screen. In one example, a single controller controls the screen, an associated filter and the mechanical indicators.
