1. A display method of a display panel, wherein the display panel comprises a backlight module and a liquid crystal panel assembled with the backlight module, and the method comprises following steps:
obtaining a real-time display frequency of the liquid crystal panel in response to a display operation of the display panel; and
regulating backlight brightness of the backlight module according to the real-time display frequency, such that display brightness of the display panel is maintained within a target brightness range,
wherein the step of regulating the backlight brightness of the backlight module according to the real-time display frequency comprises:
dividing a display frequency range of the liquid crystal panel into at least two frequency bands, and specifying each of the frequency bands to correspond to a specific backlight brightness; and
regulating the backlight brightness into the specific backlight brightness to which one of the frequency bands that includes the real-time display frequency corresponds.
