A circuit with power saving function connected to a LCD includes a display signal output module, to output a display control signal; a boosting circuit; a Content Adaptive Backlight Control (CABC) control module, to output a CABC signal; and a combining circuit, connected between the display signal output module and the CABC control module, to combine the display control signal outputted by the display signal output module and the CABC signal outputted by the CABC control module, then output a combined signal to an input port of the boosting circuit. The boosting circuit is configured to boost the combined signal and output a boosted combined signal to the LCD, thereby changing the backlighting of the LCD to save energy. |
