Application of Small Graphic Array Electroluminescent Technology for Information Display Systems

Rapid growth in the number of electronic systems on today's commercial vehicles has resulted in the proliferation of information displays. Systems for driver message centers, mobile communications, and fleet management are using flat panel displays for information management. Liquid crystal, vacuum fluorescent, and LED are commonly used display technologies. These devices are often segmented displays and are useful in presenting numeric or iconic data. Recent driver information systems have used multi-line character displays to present alphanumeric information. The use of a small graphic array display offers the benefit of presenting either alphanumeric or graphic information. Small graphic arrays that use liquid crystal technology are beginning to appear in vehicles. Graphic array displays using electroluminescent technology are also available. Electroluminescent technology offers many advantages over other flat panel display technologies and is ideally suited for application in commercial vehicles.
