Display device, electronic device having the same, and method thereof

摘要

An electronic device includes a central processing unit (“CPU”), first and second display panels, and first and second display panel drivers. The CPU provides an image signal and an input control signal. The first and second display panels respectively display images. The first and second display panel drivers drive the first and second display panels according to the image signal and the input control signal. The CPU includes an interface transmission unit outputting an interface signal to control the first and second display panel drivers. The first and second display panel drivers respectively include first and second interface receiving units receiving the interface signal from the interface transmission unit. The interface signal includes a display panel selection bit and a data bit.
