The method comprises the steps: detecting a light intensity of an environment in which a display screen currently lies; predetermining an optimal brightness value that matches the light intensity of the environment in which the display screen currently lies; comparing the current brightness value of the display screen with the optimal brightness value of the display screen; and if an absolute value of a difference between the current brightness value of the display screen and the optimal brightness value of the display screen is less than or equal to a predetermined threshold value, the process is ended, and if the absolute value of the difference is greater than the predetermined threshold value, the brightness of the display screen is adjusted by adjusting a voltage value of an analog positive power supply of the display screen."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and circuit for adjusting screen brightness and display device","description":"The present disclosure provides a method and a circuit for adjusting screen brightness and a display device including the circuit.
