Abstract: The present invention provides a brightness adjustment method, a dimming device, and a display panel. The method comprises following steps of: receiving N initial dimming signals, performing a delay processing on at least one initial dimming signal of the N initial dimming signals to obtain N dimming signals, and using the N dimming signals to perform a brightness adjustment on the N dimming regions respectively within a dimming cycle; wherein N≥2, and N is a positive integer. The method can easily eliminate horizontal blocks of the display panel and improve display effects of the display panel.
