摘要： 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.

摘要： An LCD includes a first substrate, a second substrate, a liquid crystal layer between the first and second substrates, first and second alignment films respectively disposed on the first and second substrates. The first substrate comprises multiple scanning lines and multiple data lines intercrossed with the multiple scanning lines to define multiple pixel areas. Each pixel area comprises multiple electrically interconnected first electrodes and multiple electrically interconnected second electrodes. The first electrodes and the second electrodes are disposed on different layers and mutually intersected to define multiple sub-pixel areas. Each sub-pixel area further comprises two protrusion-shaped patterns facing each other on two adjacent first electrodes where the first electrodes and the second electrodes are not overlapped. An angle within a range of 5-20 degrees is defined between the vertex connection direction of the two protrusion-shaped patterns facing each other and the rubbing direction of the first and second alignment films.
