  • Electrical luminescent lamp processing method
    Patent number: 6767268
    Abstract: An electrical luminescent lamp processing process includes the step of using a machine tool to process a design in the back electrode layer of an electrical luminescent lamp, the step of cutting contact holes in an electrically insulative layer subject to a predetermined design and then adhering the electrically insulative layer to the back electrode layer, and the step of adhering a conductor layer to the electrically insulative layer opposite to the back electrode layer over the contact holes for transmitting electricity to the design in the back electrode layer.
