摘要： A compact-size driving voltage controller is provided which can be driven with low power. The compact-size driving voltage controller which can be driven with low power includes a High output operational amplifier and a Low output operational amplifier for supplying driving voltages VcomH, VcomL to a load such as a liquid crystal display panel, an output switch for alternating between the outputs of the operational amplifiers, a Low voltage setting operational amplifier for generating a set voltage to be supplied to the non-inverted input terminal of the Low output operational amplifier, a set voltage generator including a current mirror circuit and a clamping circuit, a bias current controller for controlling the bias current flowing in each operational amplifier with a predetermined timing, and a timing controller for controlling the changeover timing of the output switch.

摘要： A signal line driving circuit includes an output section outN (where N is a natural number) for supplying an image-forming signal for red, green or blue to a sub-pixel of a display section, a voltage supply line SN connected to the output section outN, and a shorting line for electrically shorting output sections of the same color with each other during a predetermined period. By shorting output sections of the same color with each other, the charge stored in a panel-side load can be effectively redistributed to another panel-side load, thereby realizing a power conserving effect.
