Abstract
A display method of a display panel includes determining whether the display panel is in a frequency conversion state, if the display panel is in a frequency conversion state, acquiring a first frequency and a second frequency corresponding to two adjacent frames consecutively for multiple times, determining whether the display panel is in a first display mode according to a difference between the first frequency and the second frequency obtained multiple times, and if the display panel is in the first display mode, turn off a brightness adjustment function of the display panel.
Claims14
A display method of a display panel, wherein the display panel has a first display mode, a frequency of the display panel in the first display mode gradually changes, and the display method of the display panel comprises:
- determining whether the display panel is in a frequency conversion state;
- if the display panel is in the frequency conversion state, acquiring a first frequency and a second frequency corresponding to two adjacent frames consecutively for multiple times;
- determining whether the display panel is in the first display mode according to a difference between the first frequency and the second frequency obtained multiple times;
- and
- if the display panel is in the first display mode, turn off a brightness adjustment function of the display panel;
- wherein a step of determining whether the display panel is in the first display mode according to the difference between the first frequency and the second frequency obtained multiple times comprises:
- determining whether an absolute value of the difference between the first frequency and the second frequency acquired each time is less than a setting threshold for frequency mode;
- if the absolute value of the difference between the first frequency and the second frequency acquired N consecutive times is less than the setting threshold for frequency mode, determining that the display panel is in the first display mode, wherein N is a frame number for display mode determination;
- wherein the frame number for display mode determination is determined according to a first initial frequency and a second initial frequency when the display panel is in the frequency conversion state;
- wherein the first initial frequency and the second initial frequency are respectively the first frequency and the second frequency corresponding to the two adjacent frames acquired for a first time;
- and
- wherein the first initial frequency corresponds to a frame preceding the two adjacent frames, and the second initial frequency corresponds to a frame following the two adjacent frames.
