Problems solved by technology

[0003] However, when the mobile terminal is turned on under strong light during the day, if the display screen wallpaper is a dark wallpaper, no matter how much the brightness bar of the display screen is adjusted, the user cannot clearly distinguish the content of the display screen. place to see the contents of the display
When turning on the mobile terminal in a dark environment at night, since the pupils of the eyes have adapted to the dark environment, if the display screen wallpaper is a bright color wallpaper, no matter how small the brightness bar of the display screen is adjusted, the eyes will feel stinging. It will also affect vision

Embodiment 1

[0039] figure 1 It is a flowchart of a method for controlling the brightness of the display screen provided by Embodiment 1 of the present invention. This embodiment is applicable to make the brightness of the display screen suitable when the user turns on the mobile terminal under strong light or at night. The method can be controlled by a The brightness of the display screen is implemented by the system, which specifically includes the following steps:

[0040] Step 110, acquiring a trigger signal for turning on the display screen.

[0041] Wherein, the way of lighting up the display screen can be to light up by pressing the switch key or by fingerprint recognition when the mobile terminal is in standby state; when the display screen is lighted up, the mobile terminal will receive a trigger signal.

[0042] Step 120, when the acquisition time of the trigger signal is within the preset protection time period, turn on the photosensitive sensor.

[0043] Among them, the prese...

Embodiment 2

[0055] figure 2 It is a flow chart of a method for controlling the brightness of the display screen provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the above-mentioned embodiments. After obtaining the trigger signal to light up the display screen, it also includes: when the If the acquisition time of the trigger signal is not within the preset protection time period, the brightness bar of the display screen is adjusted to the normal value, and the screen wallpaper is replaced with the eye-protecting color wallpaper.

[0056] Such as figure 2 As shown, the specific steps of an optimized method for controlling the brightness of a display screen include:

[0057] Step 210: Obtain a trigger signal for turning on the display screen.

[0058] Step 220: Judging whether the acquisition time of the trigger signal is within the preset protection time period, if yes, go to step 230, otherwise go to step 290.

[0059] Step 230: Turn on th...

Embodiment 3

[0068] image 3 Shown is a schematic structural diagram of a system for controlling the brightness of a display screen provided by Embodiment 3 of the present invention. The structure of the system includes:

[0069] A trigger signal acquisition module 310 , a trigger moment detection module 320 , an environment brightness measurement module 330 and a display brightness control module 340 .

[0070] Wherein, the trigger signal acquisition module 310 is used to acquire the trigger signal for lighting the display screen; the trigger moment detection module 320 is used to turn on the photosensitive sensor when the acquisition time of the trigger signal is within the preset protection time period; the environment The brightness measurement module 330 is used to measure the current brightness of the external environment through the photosensitive sensor; the display brightness control module 340 is used to control the current brightness of the display screen according to the extern...

Abstract

The invention discloses a display screen luminance control method and system. The method includes: acquiring a screen-on trigger signal; starting a photosensitive sensor when a trigger signal acquisition moment is within a preset protection time period; measuring current external environment luminosity through the photosensitive sensor; controlling current display screen luminance according to theexternal environment luminosity. Therefore, convenience in display screen luminance control is achieved, and safety protection of human vision is realized.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a method and system for controlling brightness of a display screen. Background technique [0002] With the development of communication technology, mobile terminals have become an indispensable communication tool in people's daily life. No matter day or night, people will use mobile terminals anytime and anywhere if needed. [0003] However, when the mobile terminal is turned on under strong light during the day, if the display screen wallpaper is a dark wallpaper, no matter how much the brightness bar of the display screen is adjusted, the user cannot clearly distinguish the content of the display screen. You can see the contents of the display clearly. When the mobile terminal is turned on in a dark environment at night, since the pupils of the eyes have adapted to the dark environment, if the display screen wallpaper is a bright color wal...
