Abstract
A display device, a drive method therefor, and a drive system therefor are provided by embodiments of the present application. The drive method includes: detecting whether a spectrum of a drive signal is spread when the drive signal is received, and the drive signal is configured to drive the display panel: outputting a clock signal output from the control module to the source drive module if the spectrum of the drive signal is spread; performing spectrum spread on the clock signal according to a preset spread spectrum ratio if the spectrum of the drive signal is not spread; and outputting the clock signal with the spread spectrum to the source drive module.
Claims20
A drive method for a display device, wherein the display device comprises a control module, a source drive module, and a display panel;
- and the drive method comprises:
- detecting whether a spectrum of a drive signal is spread when the drive signal is received, and the drive signal is configured to drive the display panel;
- outputting a clock signal output from the control module to the source drive module if the spectrum of the drive signal is spread;
- performing spectrum spread on the clock signal according to a preset spread spectrum ratio if the spectrum of the drive signal is not spread;
- and
- outputting the clock signal with the spread spectrum to the source drive module.
A drive system for a display device, wherein the display device comprises:
- a control module, a source drive module, and a display panel;
- and the drive system comprises:
- a spread spectrum detection module, configured to detect whether a spectrum of a drive signal is spread when the drive signal is received, and the drive signal is configured to drive the display panel;
- a spread spectrum determination module, configured to output a clock signal output from the control module to the source drive module if the spectrum of the drive signal is spread;
- a spread spectrum module, configured to perform spectrum spread on the clock signal according to a preset spread spectrum ratio if the spectrum of the drive signal is not spread;
- and
- a data output module, configured to output the clock signal with the spread spectrum to the source drive module.
A drive method for a display device, wherein the display device comprises:
- a control module, a source drive module, and a display panel;
- and the drive method comprises:
- detecting whether a drive signal is a variable frequency signal when the drive signal is received, and the drive signal is configured to drive the display panel;
- outputting a clock signal output from the control module to the source drive module if the drive signal is a constant frequency signal;
- performing spectrum spread on the clock signal according to a preset spread spectrum ratio if the drive signal is a variable frequency signal;
- and
- outputting the clock signal with the spread spectrum to the source drive module.
