Problems solved by technology

[0003] However, when the user wakes up at night, especially in the middle of the night, when he turns on the mobile terminal to check the time, there will be glare, causing discomfort to the user, even though the screen brightness has been adjusted to the minimum, because the ambient light at night is particularly dark and the user wakes up. Eyes have difficulty adjusting to even small amounts of sudden light

Embodiment 1

[0033] figure 1 It is a flowchart of a method for adjusting the screen brightness of a mobile terminal provided by Embodiment 1 of the present invention. This embodiment is applicable to lowering the screen brightness of the mobile terminal when the user checks the time through the mobile terminal at night, and the method can be executed by the mobile terminal , including the following steps:

[0034] Step 110, receiving a trigger signal for turning on the screen of the mobile terminal.

[0035] In the standby state, the mobile terminal receives a user's trigger signal for lighting up the screen of the mobile terminal through the switch key, and lights up the screen of the mobile terminal.

[0036] Step 120, acquire the light intensity value of the surrounding environment through the light sensor.

[0037] Among them, the light sensor is also called a light sensor, which is used to sense the light intensity of the surrounding environment where the mobile terminal is located,...

Embodiment 2

[0042] figure 2 It is a flow chart of a method for adjusting the screen brightness of a mobile terminal provided by Embodiment 2 of the present invention. On the basis of Embodiment 1, this embodiment further determines that the screen brightness is lowered at night through the system time, and specifically includes the following steps:

[0043] Step 210, receiving a trigger signal for turning on the screen of the mobile terminal.

[0044] Step 220, check whether the current system time is within the preset time period, if yes, execute step 230, if not, exit.

[0045] After receiving the user's screen lighting trigger signal, the mobile terminal lights up the screen of the mobile terminal, detects whether the current system time is within the preset time period indicating night, if yes, executes step 230, and if not, exits the process. Generally, when people wake up in the middle of the night, they will use the mobile terminal to check the time, so the preset time period can...

Embodiment 3

[0053] image 3 It is a schematic diagram of a device for adjusting screen brightness of a mobile terminal provided by Embodiment 3 of the present invention. The apparatus for adjusting screen brightness of a mobile terminal provided in this embodiment is used to implement the method for adjusting screen brightness of a mobile terminal provided in Embodiment 1. like image 3As shown, the device for reducing the screen brightness of a mobile terminal at night provided by this embodiment includes: a receiving module 310 , an acquiring module 320 and a setting module 330 .

[0054] Wherein, the receiving module 310 is used for receiving the screen lighting trigger signal of the mobile terminal; the obtaining module 320 is used for obtaining the light intensity value of the surrounding environment through the light sensor; the setting module 330 is used for when the light intensity value is less than the set threshold , adjust the screen brightness of the mobile terminal to a mi...

Abstract

The invention discloses a method and device for adjusting the screen brightness of a mobile terminal. The method comprises the steps of receiving trigger signals for lightening a screen of the mobile terminal; obtaining a light intensity value of the surrounding environment through a light sensor; adjusting the screen brightness of the mobile terminal to a minimum value and replacing wallpaper with dark-colored wallpaper when the light intensity value is smaller than a preset threshold value. According to the method and device for adjusting the screen brightness of the mobile terminal, the screen brightness of the mobile terminal at night is reduced, and the screen light is prevented from glaring.

Description

technical field [0001] Embodiments of the present invention relate to the field of mobile terminal display technologies, and in particular, to a method and device for adjusting brightness of a screen of a mobile terminal. Background technique [0002] With the popularization of mobile terminals, there are more and more applications of mobile terminals, wherein time display is an indispensable function of mobile terminals, and people gradually use mobile terminals to replace traditional wristwatches to check time. [0003] However, when the user wakes up at night, especially in the middle of the night, when he turns on the mobile terminal to check the time, there will be glare, causing discomfort to the user, even though the screen brightness has been adjusted to the minimum, because the ambient light at night is particularly dark and the user wakes up. It is difficult for the eyes to adjust to even small bursts of light. Contents of the invention [0004] In view of this,...
