Embodiment Construction

[0050]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 here 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, only some structures related to the present invention are shown in the drawings but not all structures.

[0051] With the mature development of the display panel industry, display panels have different requirements for refresh rates in different application scenarios. For example, when displaying some relatively static images, the refresh rate can be reduced to save power consumption; while for higher display requirements, the refresh rate can be increased to improve display quality. Therefore, by setting the refresh frequency of the display panel to be adjustable, the power consumption of the display screen can be eff...

Abstract

The invention discloses a driving method and a driving device of a display panel. The driving method of the display panel includes: obtaining an operation instruction of the display panel; determining an application mode of the display panel according to the operation instruction; switching the refresh frequency of the display panel to a refresh frequency corresponding to the application mode according to the application mode of the display panel, and calling the application mode Corresponding driver data. Different application modes of the display panel correspond to different refresh rates, so that the seamless and smooth switching of the refresh rate of the display panel can be realized, problems such as flickering and color shift can be avoided, and problems such as stuttering and color shift at high refresh rates can be effectively solved. The phenomenon of dizziness and motion blur improves the experience effect of high refresh rate. In addition, it can ensure the display quality of the display panel at different refresh rates, reduce the number of complex instructions sent by the mainboard, thereby saving the power consumption of the mainboard and prolonging the standby time 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 and a driving device for a display panel. Background technique [0002] In the application process of the display panel, different application scenarios have different requirements on the refresh rate, so it is necessary to set the refresh rate of the display panel as a dynamic refresh rate. Due to the limitation of the pixel drive circuit of the display panel, when the refresh frequency of the display panel is adjusted from low frequency to high frequency, problems such as large luminous brightness of the display panel, instantaneous flickering, abnormal brightness of every column and uneven display are prone to occur. Contents of the invention [0003] The invention provides a driving method and a driving device of a display panel to realize the automatic switching of the refresh frequency of the display panel, and at the same ti...
