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 a synchronization control (SC) signal. The driver module generates a plurality of switching signals and an image refresh signal based on the SC signal. The switching signals cause the LED array to emit light in a line scan manner. The image refresh signal is related to one of the switching signals that corresponds to a last line of the line scan in each line scan cycle, and is further related to refreshing of images on a display constituted by the light emitting module and the display module.
