Bidirectional Display for Operator Control Panel

       Disclosed is a method/design for changing the read
direction of a LED- type display by the user.  This becomes necessary
for machines which have two or more customer-selectable orientations.

      Access to the display is obtained via a snap-out lens covering,
which is part of the machine's operator control panel (Fig. 1).  The
display may be rotated since the LED units are mounted to a flexible
circuit which in turn is affixed to a pivoting member (Fig. 2).

      The pivoting member has intergal detents and stops which
provide precise radial location of the display.  In order to minimize
the overall display size, the accompanying driver circuitry and
components would be located on the machine planar board.  The flex
circuit, connected to the planar, would carry the  signal and power
lines to the display.

      This type of display unit most often is used to provide machine
status and diagnostic information to the operator or service
personnel.
