Abstract
The viewing angle of a liquid crystal display may be controlled by storing a digital code which represents the viewing angle, and converting the stored digital code to an analog voltage which is applied to the bias input of the liquid crystal display. To adjust the viewing angle, a new digital code is stored using keypad input. The invention is particularly suitable for microprocessor controlled displays, and eliminates the need for a hinged or pivoted display, or a viewing angle adjustment knob.
