Abstract
A display unit having a plurality of light emitting segments is directly attached to a circuit board, thereby avoiding use of a separate encapsulated display device. The circuit board is provided with a plurality of electrical conductors permanently attached to its component mounting surface. Electrically conductive leads extend between the light emitting segments of the display unit and the electrical conductors attached to the circuit board. The display unit includes a base supporting member to which the light emitting segments are attached in a desired configuration. The base member is preferably glued with an electrically conductive glue to an electrical conductor attached to the circuit board, thereby simultaneously physically connecting the base member directly and permanently to the circuit board and electrically connecting a common terminal of the light emitting segments to the electrical conductor on the circuit board. The circuit board is of sufficient size to allow the connection of other electronic components, such as integrated circuits and the like, to the electrical conductors on the circuit board. The electrical circuit assembly thus comprised is disclosed for exemp…
