The invention discloses a display and the source electrode driving component. The source electrode driving component has a sampling/remaining circuit, a first multiplexer, a first low-voltage amplifier, a high-voltage amplifier and a second multiplexer. The sampling/remaining circuit is connected to the first and second voltage by two input ends for outputting the first sampling remaining voltageand the second sampling remaining voltage by two output ends. The first multiplexer has two input ends which are respectively connected to the output end of the sampling/remaining circuit and the first multiplexer has two output ends which are respectively used for selectively outputting the first sampling remaining voltage and the second sampling remaining voltage according to the polar signal. The first low-voltage amplifier is connected to one of the output ends of the first multiplexer to output the low pixel voltage. The high-voltage amplifier is connected to another output end of the first multiplexer to output the high pixel voltage. The second multiplexer respectively outputs the low pixel voltage and the high pixel voltage according to the polar signal to two data lines of the display panel.
