Abstract
The invention describes a method for electronically adjusting the viewing angle of a liquid crystal display within a panel fixed in location by the structure within which it is located, such as an electronic flight indicator unit. The adjustment in viewing angle is achieved by changing the bias voltage to alter the pre-tilt angle of the liquid crystal layer.
