The automobile instrument panel is undergoing a revolutionary transition from mechanical and electromechanical displays to all-electronic displays. This is not an easy transition in that the "ideal" automotive display does not exist and all principal candidates have significant limitations. To identify the obstacles standing in the way of successful application of these candidate displays, we examine these limitations from the view of system performance and cost, concluding that innovative approaches to implementing the electronic control of the display can both improve display performance and reduce system cost. Specifically, the development of a high performance, cost effective thin-film transistor (TFT) technology is essential to the successful implementation of automotive quality flat panel dot matrix displays. The potential of competitor TFT technologies will be assessed for their ability to provide the performance required in mature flat panel displays. |
