Abstract: A scan-type display apparatus includes an LED array, a display module, a control module and a driver module. The LED array has a common anode configuration. The control module generates a synchronization control (SC) signal. Based on the SC signal, the driver module outputs an input voltage to scan lines of the LED array sequentially without overlapping in time so as to drive LEDs of the LED array to emit light in a line scan manner, and generates an image refresh signal that is related to the output of the input voltage to one of the scan lines which corresponds to a last line of the line scan in each line scan cycle and that is further related to refreshing of images on a display constituted by the LED array and the display module.
