The method comprises: acquiring a brightness adjustment instruction and a target display brightness value of a display panel, a display brightness value representing backlight brightness of the display panel; adjusting a duty cycle of the light-emitting control signal based on the target display brightness value of the display panel; driving LEDs of a corresponding row in a backlight source to emit light by the adjusted light-emitting control signal. Each time the duty cycle of the light-emitting control signal needs to be adjusted, a duty cycle of each pulse cycle of a part of N pulse cycles of the light-emitting control signal is selected for corresponding adjustment, thus backlight brightness adjustment accuracy of the display panel is effectively improved, and an adjustable range of backlight brightness of the display panel is wider."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Brightness adjustment method, device and display apparatus","description":"Disclosed is a brightness adjustment method, a device and a display apparatus.
