Example

[0023] First embodiment

[0024] See figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the method for adjusting the backlight brightness of the display screen provided by the present invention.

[0025] Step S101: Obtain the shaking frequency of the mobile terminal.

[0026] Preferably, a pedometer or exercise software is used to obtain the shaking frequency of the mobile terminal. The shaking frequency of the mobile terminal is the average movement distance of the user per second or minute. For example, the shaking frequency of the mobile terminal is 60 meters. every minute.

[0027] Step S102: Match the preset frequency interval to which the shaking frequency belongs, and each preset frequency interval corresponds to a backlight brightness adjustment strategy.

[0028] Preferably, the preset frequency interval is divided into a first preset frequency interval, a second preset frequency interval, and a third preset frequency interval, and the corresponding bac...

[0033] Second embodiment

[0034] See figure 2 , figure 2 It is a schematic flowchart of the second embodiment of the method for adjusting the backlight brightness of the display screen provided by the present invention.

[0035] Step S201: Acquire the shaking frequency of the mobile terminal.

[0036] Preferably, a pedometer or exercise software is used to obtain the shaking frequency of the mobile terminal. The shaking frequency of the mobile terminal is the average movement distance of the user per second or minute. For example, the shaking frequency of the mobile terminal is 60 meters. every minute.

[0037] Step S202: Match the preset frequency interval to which the shaking frequency belongs, and the preset frequency interval is divided into a first preset frequency interval, a second preset frequency interval, and a third preset frequency interval by a first judgment value and a second judgment value. Set the frequency range.

[0038] Wherein, each of the preset frequency inte...

[0063] The third embodiment

[0064] See image 3 , image 3 It is a schematic structural diagram of the backlight brightness adjustment device of the display screen in the mobile terminal provided by the present invention.

[0065] The device includes a first acquisition module 31, a first matching module 32, a first adjustment module 33, a first judgment module 34, a second acquisition module 35, a second matching module 36, a second judgment module 37, and a second adjustment module 38.

[0066] Wherein, the first obtaining module 31 is configured to obtain the shaking frequency of the mobile terminal.

[0067] For example, the shaking frequency of the mobile terminal acquired by the first acquiring module 31 is 60 meters per minute.

[0068] The first matching module 32 is configured to match the preset frequency interval to which the shaking frequency acquired by the first acquiring module 31 belongs, wherein each preset frequency interval corresponds to a backlight brightness a...

Abstract

The invention discloses a backlight brightness adjustment method for a display screen and a mobile terminal. The method comprises the following steps: obtaining shaking frequency of the mobile terminal, matching a preset frequency section to which the shaking frequency belongs, wherein each preset frequency section corresponds to a backlight brightness adjustment strategy, and adjusting the backlight brightness of the display screen in the mobile terminal according to the backlight brightness adjustment strategy corresponding to the preset frequency section to which the shaking frequency belongs. By adopting the backlight brightness adjustment method disclosed by the invention, the flicker problem of the backlight brightness of the display screen in the mobile terminal is avoided, the service life of the display screen is prolonged, the visual acuity of a user is protected and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method for adjusting the brightness of a backlight of a display screen and a mobile terminal. Background technique [0002] Existing mobile terminals can automatically adjust the brightness of the backlight of the display screen by acquiring the ambient light brightness value. The mobile terminal can perceive the ambient light brightness value through the light sensor, and automatically adjust the backlight brightness of the display screen according to the ambient light brightness value. When the ambient light brightness value decreases, the backlight brightness of the display screen is adjusted to a lower backlight brightness. If When the ambient light brightness value increases, the backlight brightness of the display screen is adjusted to a higher backlight brightness, thereby achieving the purpose of reducing product energy consumption and protecting users' eyesigh...
