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.

Scan-type display apparatus, and driving device and driving method thereof

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.

Scan-type display apparatus, in which refreshing of images on a display thereof can occur when a line scan cycle of a light emitting diode array of the display ends, and driving method thereof

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.
