Hybrid display instrument, particularly for use in an automobile instrument panel
First Claim
1. A hybrid display instrument, comprising:
- means for defining an elongated display area having at least one arcuate dial for displaying analog information and a band along substantially a full length of a longitudinal edge of said display area;
at least one pointer mounted to sweep across said arcuate dial and provided with a drive responsive to said analog information for indicating said analog information by a position of said pointer along said dial;
means outside said area for generating symbolic information and for projecting said symbolic information into said display area along said band; and
a plurality of symbolic information display cells provided along said band and visible and readable simultaneously with said dial and receiving symbolic information projected into said display area by said means for generating symbolic information, whereby said cells provide respective, selectively fixed and variable information readable together with said analog information said band being provided along a lower edge of said display area, and said pointer having a pivot below a bottom of said band.

Abstract
Even with a small display area of a hybrid display instrument for the instrument panel of a compact automobile, an optimum presentation of information can be obtained if the display area is limited to approximately the upper half of the instrument housing front panel and the symbolic information displays of fixed and variable symbol cells are rendered by a projection technique in a row along the bottom edge of the display area. In return, the electrical and optical control devices for the cells, and possibly even the system of cells itself, is moved into the lower area of the instrument housing so that these will take up no space in the actual display area. Above the row of symbolic display units, there extends the arc-shaped dial of at least one analog gauge, the pointer drive shaft of which is supported behind (or even below) the display edge for the symbolic information displays.
