Abstract: The disclosure provides a driving device for a self-luminous display panel and an operation method thereof. The driving device includes multiple GAMMA voltage circuits, a group of driving channels, and a routing circuit. Each driving channel is coupled to the corresponding GAMMA voltage circuit to receive a corresponding group of GAMMA voltages. Each driving channel converts corresponding sub-pixel data into a corresponding gray scale voltage based on the corresponding group of GAMMA voltages. The routing circuit is coupled to the output terminals of the driving channels. The routing circuit dynamically changes the coupling relationship between the driving channels and multiple data lines of the self-luminous display panel during different scanning periods.
