17 Claims

1. A display method of a display device, comprising following steps:

obtaining a target display frequency and a target backlight brightness value of a target display device;

obtaining a first display frequency and a first backlight brightness value of the target display device within a predetermined period;

confirming a backlight brightness compensation value of the target display device within the predetermined period according to a differential between the target display frequency and the first display frequency when the first display frequency and the target display frequency are different; and

compensating for the first backlight brightness value according to the backlight brightness compensation value;

wherein before the step of obtaining the target display frequency and the target backlight brightness value of the target display device, the method comprises following steps:

inputting an enabling signal into a timing controller of the target display device, wherein the enabling signal comprises a vertical blanking (VBlank) period; and

obtaining a refresh mode of the target display device;

wherein when the refresh mode of the target display device has a constant display frequency, the VBlank period is a constant VBlank period;

when the refresh mode of the target display device has a variable display frequency, the VBlank period is a variable VBlank period; and

wherein the step of obtaining the target display frequency and the target backlight brightness value of the target display device comprises following steps:

obtaining a proportion of usage time of different display frequencies of the target display device within a historical period;

obtaining a second display frequency of the target display device, wherein a proportion of usage time of the second display frequency is greater than or equal to a first threshold value; and

setting the second display frequency to be the target display frequency of the target display device, and setting a backlight brightness value corresponding to the second display frequency to be the target backlight brightness value of the target display device.
