Abstract
A scan-type display apparatus includes a light emitting module, a display module, a control module and a driver module. The light emitting module includes an LED array having a common anode configuration. The control module generates an image stream, a plurality of switching signals that cause the LED array to emit light in a line scan manner, and an image refresh signal that is related to refreshing of images on a display constituted by the light emitting module and the display module. The driver module generates a drive output to drive the display module, such that the display shows images represented by the image stream and that the refreshing of images on the display is synchronous to the line scan.
