Embodiment 1

[0035] Embodiment 1 of the present invention provides an automatic backlight adjustment method for automatically turning on a mobile terminal, and this embodiment will be described in detail below with reference to the accompanying drawings. figure 1 It is a flow chart of the method of Embodiment 1 of the present invention, please refer to figure 1 , the method of the embodiment of the present invention includes the following steps:

[0036] Step S101, when the screen of the mobile terminal is turned on, detect whether the mobile terminal is currently in the automatic backlight adjustment mode;

[0037] Specifically, in the framework layer of Android design, the power management module (PowerManager) sets a listener for the database used by the setting module, and monitors the item of automatic backlight in the database. When the item of automatic backlight changes, it monitors The device will monitor it, and then update the local record, so the backlight adjustment mode set ...

Embodiment 2

[0066] Embodiment 2 of the present invention provides a device for automatically turning on the automatic backlight adjustment of a mobile terminal, please refer to image 3 , the device consists of:

[0067] The backlight mode detection module 31 is used to detect whether the mobile terminal currently opens the automatic backlight adjustment mode when the mobile terminal is on the screen;

[0068] The backlight value acquisition module 32 is used to obtain the current screen backlight brightness value of the mobile terminal if the mobile terminal does not currently open the automatic backlight adjustment mode;

[0069] The backlight value judging module 33 is used to judge whether the current screen backlight brightness value of the mobile terminal is in the lowest brightness interval;

[0070] In this implementation, preferably, the lowest brightness range is 5-15 lux.

[0071] The light intensity acquisition module 34 is used to sample and acquire the current ambient ligh...

Abstract

The invention discloses a method and a device for automatically starting automatic backlight adjustment of a mobile terminal. The method comprises the following steps: when a screen of the mobile terminal is bright, detecting whether the mobile terminal starts an automatic backlight adjustment mode or not at present; if the mobile terminal does not start the automatic backlight adjustment mode at present, obtaining a current screen backlight brightness value of the mobile terminal; judging whether the current screen backlight brightness value of the mobile terminal is at a lowest brightness interval or not; if the current screen backlight brightness value of the mobile terminal is at the lowest brightness interval, sampling to obtain a current environment light strength value; judging whether the current environment light strength value is at a strong light interval or not; if the current environment light strength value is at the strong light interval, starting the automatic backlight adjustment mode; and automatically adjusting screen backlight according to the current environment light strength value. According to the method and the device disclosed by the invention, a condition that screen display can not be seen under strong light, caused by that a screen backlight value is too low, can be avoided; the design is reasonable and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminals, and more specifically relates to a method and device for automatically turning on a mobile terminal for automatic backlight adjustment. Background technique [0002] Existing mobile terminals (such as mobile phones) with display screens are often provided with a backlight brightness adjustment function, and there are two ways to adjust the backlight brightness of the screen: 1. Manually enter the adjustment backlight brightness menu to adjust; 2. Set the mobile terminal to automatically Adjust the brightness of the backlight. [0003] According to usage habits, some users are not accustomed to using the automatic backlight adjustment mode, but choose the manual backlight adjustment mode. Therefore, the following situations will occur to this part of users: When using the mobile terminal at night, the brightness value of the screen backlight (that is, the backlight value ) to the...
