ABSTRACT:
A display system and method for image overlapping are described. The display system includes a detection module, a transmission interface, a switch output device and a control module. The detection module receives a first image and detects synchronous signals of the first image. The transmission interface is coupled to the detection module and receives a second image having position display information. The switch output device is coupled to the detection module to output the first image. The control module coupled to the detection module, the transmission interface and the switch output device, respectively, dominates the switch output device to output the second image according to the synchronous signals and the position display information such that the second image overlaps the first image.
