Problems solved by technology

[0002] When the display panel is displayed, adopting a high refresh rate can improve the fluency of the display panel display and improve the visual enjoyment of the human eye, but at the same time, it will increase the power consumption of the display panel
When the display panel is driven by a scan signal in multi-scan pulse mode, the power consumption of the display panel will further increase

Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, the drawings only show some but not all structures related to the present invention.

[0037] In the prior art, when the display panel is driven, a scan signal in a multi-scan pulse mode can be used to drive the pixel unit in the display panel to emit light, so that the pixel circuit in the pixel unit repeats many times in the non-light-emitting stage, and the periodic charging of the pixel circuit is improved. The frequency of discharge can improve the smear problem caused by the hysteresis effect of the transistor in the pixel circuit. Illustratively, figure 1 A timing diagram of a scan signal in a multi-scan pul...

Abstract

The invention discloses a driving method, a driving device and a display device of a display panel. The driving method of the display panel includes: determining the refresh rate mode of the display panel according to the refresh rate of the display panel; adjusting the number of scanning signal pulses provided to each row of sub-pixels in the display panel within a frame period according to the refresh rate mode; wherein, refreshing The higher the refresh rate corresponding to the refresh rate mode, the fewer the number of scan signal pulses. The high refresh rate increases the charge and discharge frequency of the pixel circuit, which improves the smear problem of the display panel. Power consumption, so that the smear problem and power consumption of the display panel can be comprehensively considered through the refresh rate and the number of scanning signal pulses, and the power consumption of the display panel can be reduced while ensuring the display effect of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technologies, and in particular, to a driving method, a driving device and a display device for a display panel. Background technique [0002] When the display panel is displayed, using a high refresh rate can improve the display fluency of the display panel and improve the visual enjoyment of the human eye, but at the same time lead to an increase in the power consumption of the display panel. When the display panel is driven by a scan signal in a multi-scan pulse mode, the power consumption of the display panel will further increase. SUMMARY OF THE INVENTION [0003] The present invention provides a driving method, a driving device and a display device for a display panel, so as to reduce the power consumption of the display panel on the basis of ensuring the display effect of the display panel. [0004] In a first aspect, an embodiment of the present invention provides a method f...
