Abstract
A multiplexer circuit and a display panel thereof are provided. The multiplexer circuit includes a first switch, a second switch, and a pull-down circuit. The first switch has a first terminal coupled to a first source line, a control terminal receiving a first switching signal, and a second terminal coupled to a source driver. The second switch has a first terminal coupled to a second source line, a control terminal receiving a second switching signal, and a second terminal coupled to the source driver. The pull-down circuit is coupled to the control terminal of the first switch and receives a system low voltage. The pull-down circuit transmits the system low voltage to the control terminal of the first switch during a rising edge of the second switching signal to turn off the first switch before the second switch is turned on.
