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.
