Abstract
A source drive circuit effects alternate current driving of a polarity of a source signal that is supplied to a source bus line. A control circuit controls a gate drive circuit and the source drive circuit so that in a partial area, a pixel voltage is supplied at a first refresh rate and so that in an area other than the partial area, the pixel voltage is supplied at a second refresh rate that is lower than the first refresh rate and that is a frequency of a fraction of an odd number-th of the first refresh rate.
Claims8
A display device comprising:
- a display panel including a pixel electrode and a common electrode that forms an electric field with the pixel electrode;
- a gate drive circuit that supplies a gate signal to a gate bus line of the display panel;
- a source drive circuit that supplies a pixel voltage to the pixel electrode by sequentially supplying a source signal to a source bus line of the display panel;
- and
- a control circuit that controls a refresh rate that is a frequency at which an image displayed on the display panel is rewritten,
- wherein
- the source drive circuit effects alternate current driving of a polarity of a source signal that is supplied to the source bus line, and
- the control circuit controls the gate drive circuit and the source drive circuit so that in a partial area, the pixel voltage is supplied at a first refresh rate and so that in an area other than the partial area, the pixel voltage is supplied at a second refresh rate that is lower than the first refresh rate and that is a frequency of a fraction of an odd number-th of the first refresh rate.
