ABSTRACT:
A photographic camera is provided with a display including organic electroluminescent material energizable in patterns representing camera information. The patterns are defined by electrically isolated illumination elements that are controlled to emit light by selectively applying a voltage to the elements forming the desired pattern. The material may be chosen to emit light in different colors representing levels of concern associated with camera conditions. Certain features provide a display having an in-line array of alpha-numeric character generators comprising a matrix of closely spaced illumination elements and a control for energizing selected combinations of the elements to emit light collectively defining alpha-numeric characters. Display brightness can be adjusted by changing the applied power as a function of the ambient light conditions to enhance viewability of the display.
