Abstract
An interconnection device for connecting a plurality of LCD contacts with a plurality of base circuit contacts. The interconnection device includes a non-conductive body having a U-shaped notch located for self-aligning engagement with a LCD driver chip. In addition, the non-conductive body includes at least one conductive lead. The conductive lead includes a first contact and a second contact that emerge from the non-conductive body. The contacts of the non-conductive body engage corresponding contacts of the LCD and base circuit board when the non-conductive body is engaged in alignment with the LCD driver chip.
Claims21
A method of aligning an electrical connector with a chip-on-glass liquid crystal display and a circuit board, the circuit board having a first electrical contact thereon, the liquid crystal display including a glass substrate, a second electrical contract on the glass substrate, and a driver chip mounted on the glass substrate at a fixed location relative to the second electrical contract, the method comprising the steps of:
- directly engaging an exterior surface of the driver chip with the electrical connector to align the second electrical contact with a third electrical contact carried on the electrical connector;
- and
- engaging the circuit board with the electrical connector to align the first electrical contact with a fourth electrical contact carried on the electrical connector.
An electrical connector for use in an electronic assembly including a first substrate with a surface defining a first plane and having a first electrical contact thereon, and a second substrate with a surface defining a second plane and having at least part of an electronic circuit thereon, the at least part of an electronic circuit including a second electrical contact and an electronic component mounted on the second substrate at a fixed location relative to the second electrical contact, the electrical connector comprising:
- third and fourth electrical contacts electrically connected by a conductor;
- a non-conductive body carrying the third and fourth electrical contacts and the conductor, the third and fourth contacts having fixed locations on the body relative to each other;
- a first surface on the body to engage a surface on the electronic component to align the third electrical contact with the second electrical contact in a direction that is nominally parallel to the second plane;
- and
- a second surface located on the body to engage a surface on the first substrate to align the fourth electrical contact with the first electrical contact in a direction that is nominally parallel to the first plane.
