| description | A display apparatus has a clock generating circuit, a drive waveform generating circuit, and a display panel. The drive waveform generating circuit is used to generate a drive waveform by using a clock from the clock generating circuit, and the display panel is used to display an image in accordance with the drive waveform. The clock generating circuit generates a clock whose frequency varies continuously. The drive waveform generating circuit drives the display panel by outputting a drive waveform whose frequency varies in accordance with the frequency varying clock so as to spread out noise that the display panel emits. Therefore, peak values of the noise can be reduced. |
