Abstract

The embodiment of the invention provides a method and device for adjusting backlight brightness, and the method comprises the steps: a second node obtains a first backlight parameter, and the first backlight parameter comprises a first backlight interval, a first repetition rate, and a first jump rate; the second node configures a second backlight parameter according to the first backlight parameter, the second backlight parameter comprises a second backlight interval, a second repetition rate and a second jump rate, the second backlight interval is smaller than the first backlight interval, the second repetition rate is larger than the first repetition rate, and the second jump rate is smaller than or equal to the first jump rate; and the second node adjusts the backlight brightness according to the second backlight parameter. Through the second repetition rate and the second jump rate, the number of repetition times of each backlight value in the second backlight interval is increased, and the difference value between the maximum value and the minimum value of the second backlight interval is reduced, so that the backlight brightness variation of the second backlight interval is reduced, the backlight brightness in the second backlight interval changes slowly, the flicker feeling of the display screen is reduced, and the display effect is improved. Therefore, the backlight brightness is adjusted.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of display screens, and in particular, to a method and device for adjusting backlight brightness. Background technique [0002] With the continuous development of science and technology, people use more and more types of electronic devices, such as mobile phones, tablets and other electronic devices with display screens. [0003] Generally, electronic devices with a display screen have the function of automatically adjusting the backlight brightness. In a bright environment, the electronic device will automatically brighten the backlight brightness of the display screen. In a darker environment, the electronic device will automatically The backlight of the display is dimmed. [0004] In the process of adjusting the backlight brightness of the display screen in an existing device with a display screen in a dark environment, the display screen may flicker, so that the user may experience...
