The present invention provides a source driving circuit and an LCD device. The source driving circuit includes output channels, and each output channel includes a first switch element, a second switch element, a first output end, and a second output end. The first switch element and the second switch element are respectively connected to the first output end and the second output end. When the first switch element is turned on, the output channel outputs a display signal, and when the second switch element is turned on, the output channel provides recycled charges which are generated when the display signal is changed from a positive voltage to a negative voltage. The source driving circuit can recycle charges to make the most of charges generated when the display signals change from positive voltages to negative voltages and reduce power consumption of the LCD device.
A source driving circuit, comprising a plurality of output channels, wherein each output channel comprises a first switch element, a second switch element, a first output end, and a second output end, the first switch element is connected to the first output end, the second switch element is connected to the second output end, when the first switch element is turned on, the output channel outputs a display signal through the first switch element and the first output end, and when the second switch element is turned on, the output channel provides recycled charges through the second switch element and the second output end, and the recycled charges are generated when the display signal outputted by the first output end is changed from a positive voltage to a negative voltage.
An LCD (liquid crystal display) device, comprising a source driving circuit and a plurality of data lines, the source driving circuit comprising a plurality of output channels, and the plurality of the output channels are respectively connected to the plurality of the data lines to provide display signals to the plurality of the data lines, wherein each output channel comprises a first switch element, a second switch element, a first output end, and a second output end, the first switch element is connected to the first output end, the second switch element is connected to the second output end, when the first switch element is turned on, the output channel outputs a display signal through the first switch element and the first output end to a corresponding data line, and when the second switch element is turned on, the output channel provides recycled charges through the second switch element and the second output end, and the recycled charges are generated when the display signal outputted by the first output end is changed from a positive voltage to a negative voltage.
