Design and Implementation of Organic LED-based Displays for Signage Application

摘要

Organic light-emitting diodes (OLEDs) have been utilized successfully for various applications such as microdisplays in cell-phones and digital dameras. However, the application of OLEDs for large area signage displays has not yet been established. This paper presents novel design techniques for implementing OLEDs as light sources for signage application. The designs are examined on the basis of signage uniformity, cost and manufacturing complexity. Advantages and limitations of each design are described. It is determined that a trade-off is required to choose the design. The most optimal design is chosen for implementation and evaluation. Measurement results with the optimal design are described.
