Multi-display driving circuit and method of driving display panels

Abstract

A multi-display (e.g., dual-display) driving circuit includes a first display driving circuit configured to receive a first display signal and a second display signal from an external source (e.g., CPU) through a first interface, and to drive a first display panel in response to the first display signal and to output the second display signal through a second interface of the first display driving circuit. The second display signal is transmitted via the second interface to a second driving circuit configured to drive a second display panel. Therefore, the complexity of the wiring (e.g., through a hinge of a folding phone, and between a CPU and first and second displays) of the multi-display device may be reduced, and the electromagnetic interference (EMI) characteristics of the multi-display device may be enhanced.
