Abstract: An adaptive multi-area frame rate display system and a method employed are provided. The method includes: dividing a display panel into a plurality of display areas and setting a plurality of compensation parameter sets corresponding to a plurality of frame rates; receiving display stream data; controlling the plurality of display areas of the display panel to display an image corresponding to the display stream data; performing a multi-area frame rate calculation operation to obtain a frame rate of each of the plurality of display areas; and, for each of the display areas, applying the compensation parameter set to which the frame rate of each of the display areas corresponds, so as to compensate an image subsequently displayed in each of the display areas.

Abstract: A driving circuit and a synchronization method thereof for a multi-panel display device are provided. The driving circuit includes a first driving chip and a second driving chip which share a power circuit. One of the first driving chip and the second driving chip is set as a master driving chip or a slave driving chip based on a control signal. The master driving chip transmits a power enable signal and a control signal to the power circuit, which triggers the power circuit providing power voltages to the master driving chip and the slave driving chip. When the master driving chip transmits a timing control signal to the slave driving chip, the slave driving chip performs a power synchronization operation to synchronize with the master driving chip based on the timing control signal.
