ABSTRACT:
The present invention discloses an integrated circuit (IC) driver chip for electroluminescent (EL) device, including an EL display-data-control block (DCB) and an EL display-segment-driver block (SDB), wherein said DCB stores the data for display and generates data-control-pulses for the EL segment display; and said SDB receives the data from the DCB and then drives the EL segments to display the desired information in real-time. This integrated circuit driver chip is suitable to be used to control and drive a multiple segment EL display. The applications of the IC include, but are not limited to, the display alphanumeric digits and image information. By cascading multiple IC driver chips together, it is possible to enlarge the number of display segments.
