Abstract: A scan-type display device control circuit is suitable for receiving successive frame data and driving a light-emitting diode (LED) display device accordingly. The scan-type display device control circuit includes a ping-pong buffer, a data storage controller, a line scan controller, a display buffer, and a scrambled pulse width modulation (PMW) signal generating device. The scan-type display device control circuit can utilize frame data circularly and repeatedly, so as to prevent a great mass of data from being transmitted repeatedly. Therefore, a band width for inputting data can be reduced significantly. Furthermore, the scrambled PMW signal generating device can scramble a PMW signal with a long period into a plurality of scrambled PMW signals with a short period. Therefore, the refresh rate can be efficiently enhanced without changing the band width for inputting data.
