摘要： Provided are a power supply circuit and a display device which are capable of enhancing power efficiency even when applied to a display panel whose current consumption varies. The power supply circuit boosts and outputs an input voltage using a booster chopper circuit. A frequency control circuit changes a frequency of a clock signal, which controls a switch of the chopper circuit, in accordance with a load of the power supply circuit. The frequency control circuit divides an operation of the display device into a display effective period at a high load and a vertical retrace period at a low load, based on a vertical synchronizing signal and a horizontal synchronizing signal. The frequency control circuit sets the frequency of the clock signal in a high-load period to be higher than that in a low-load period.

摘要： A display device includes a display panel and a driving circuit for driving each pixel of the display panel, in which a VCCIO voltage and a VCC voltage equal to or larger than the VCCIO voltage (VCCIO≦VCC) is inputted to the driving circuit. The driving circuit has a first level conversion circuit for converting a signal voltage level from a VCCIO voltage level to a VCC voltage level, and a level sense circuit for detecting a state in which the VCCIO voltage is not inputted. When the state in which the VCCIO voltage is not inputted is detected in the level sense circuit, operation of the first level conversion circuit is stopped. The driving circuit has a Vdd control signal for controlling operation of a Vdd voltage generation circuit, and the level sense circuit is a NAND circuit having the VCC voltage as a power supply voltage and having the VCCIO voltage and the Vdd control signal as inputs.
