Abstract

A display panel is provided. A pixel array includes a plurality of first subpixels, a first source line coupled to the first subpixels, a plurality of second subpixels displaying the same with the first subpixels, and a second source line coupled to the second subpixels. A multiplexer circuit includes a first switch coupled between the first source line and a source driver and a second switch coupled between the second source line and the source driver. A first compensation capacitor couples between the first source line and a reference voltage, and a capacitance value thereof is related to a cut-off time point of the first switch. A second compensation capacitor couples between the second source line and the reference voltage, and a capacitance value thereof the second compensation capacitor is related to a cut-off time point of the second switch different from the cut-off time point of the second switch.
