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.

Abstract: An improved key system incorporates a number of electrical components. In one main aspect, the key is provided with electrical communication to components on the vehicle when the key is inserted into the ignition. The key connects to an antenna associated with the vehicle, such that the combined antenna size is greater than would otherwise be possible. In this application, the antenna is utilized for garage door opener purposes, and a switch is mounted on the key for actuation of the garage door opener. In another aspect, the key is recharged when inserted into the ignition. Further, the key may be provided with various other functions such as memo, vehicle deactivation, two-way communication, and other security applications. In embodiments of the key, the switches are positioned relative to a thumb area such that inadvertent actuation of the switches is made less likely.

Abstract: A transparent EL display screen has a frame or rim member along only one edge of the screen. The screen is mounted within a vehicle interior so that it can be put in a position above the instrument panel and within the normal line of sight of a driver. Since the display screen is transparent and does not include a frame or rim around its entire parameter, 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 drivers that are used to selectively illuminate the pixels on the display screen.
