Problems solved by technology

[0003] Therefore, the above-mentioned brightness adjustment mechanism has the following problems, for example: 1. After the user turns off the screen indoors, he goes to the outdoor sunlight and then lights up the mobile phone. The low-brightness display under the sun is not clear; 2. Similarly, after the user turns off the screen under the outdoor sunlight, he goes indoors and then turns on the phone. When the mobile phone is displayed indoors with high brightness, there is a dazzling feeling

Embodiment 1

[0044] figure 1 It is a schematic flowchart of the first embodiment of a brightness adjustment method of the present invention. The brightness adjustment method is applied to a mobile terminal, and the method flow shown in this embodiment includes the following steps:

[0045] In step S11, when the mobile terminal receives a signal to turn on the screen when the screen is turned off, the light sensitivity value of the current ambient light is acquired. Wherein, the mobile terminal may be an electronic device such as a smart phone or a tablet computer. In this implementation manner, the light sensitivity value of the current ambient light is acquired through a photosensitive element, and the photosensitive element may be a light sensor.

[0046] Specifically, in response to the pressing operation of a physical button (such as a power button) or when no operation on the mobile terminal is received within a preset time (such as 15 seconds), the mobile terminal turns off its scr...

Embodiment 2

[0055] figure 2 It is a schematic flowchart of the second embodiment of a brightness adjustment method of the present invention. The brightness adjustment method is applied to a mobile terminal, and the method flow shown in this embodiment includes the following steps:

[0056] Step S21 , when the mobile terminal receives a signal to turn on the screen when the screen is off, start the light-sensing element to work and control the light-sensing element to sense the light-sensing value of the current ambient light.

[0057] In this embodiment, when the display screen of the mobile terminal is in the on state, the photosensitive element is in the working state. When the mobile terminal enters the screen-off state, the photosensitive element is controlled not to work, that is, the brightness of the ambient light is not sensed; until the mobile terminal receives a signal to turn on the screen, the photosensitive element is started to work, thereby achieving the purpose of power ...

Embodiment 3

[0064] image 3 It is a schematic flowchart of the third embodiment of a brightness adjustment method of the present invention. The brightness adjustment method is applied to a mobile terminal, and the method flow shown in this embodiment includes the following steps:

[0065] Step S31 , when the mobile terminal enters the screen-off state, control the light-sensing element to maintain the working state and sense the light-sensing value of the current ambient light in real time.

[0066] In this embodiment, no matter whether the screen of the mobile terminal is turned on or off, the light-sensing element is controlled to maintain the working state and sense the light-sensing value of the current ambient light in real time.

[0067] Step S32, when a signal to turn on the screen is received, the brightness level value corresponding to the light perception value of the current ambient light is acquired.

[0068] In this embodiment, the photosensitive element is kept in the work...

Abstract

The invention provides a brightness adjustment method. The brightness adjustment method is applied to a mobile terminal. The brightness adjustment method comprises the steps of acquiring a light perception value of the current ambient light when the mobile terminal receives a screen-on signal at a screen-off state, acquiring a brightness grade level corresponding to the light perception value of the current ambient light, turning on the screen and adjusting the display brightness of the screen according to the acquired brightness grade value. The invention further provides a brightness adjustment device and a mobile terminal. According to the invention, the light perception value of the current ambient light is acquired before the screen is turned on at the screen-off state so as to adjust the display brightness of the screen, thereby rapidly responding to environmental changes, and optimizing a screen brightness automatic adjustment effect.

Description

technical field [0001] The present invention relates to the field of mobile terminals, in particular to a method and device for adjusting brightness and a mobile terminal. Background technique [0002] Some electronic devices (such as mobile phones and tablet computers) have a display brightness automatic adjustment function. Taking mobile phones as an example, the current automatic screen brightness adjustment function will turn off the light perception after the screen of the mobile phone is turned off. When the screen is turned on again, the mobile phone will first display according to the screen brightness before the screen is turned off, then turn on the light sensor to detect the ambient light brightness, and then display the screen brightness based on the detected current ambient light brightness. [0003] Therefore, the above-mentioned brightness adjustment mechanism has the following problems, such as: 1. After the user turns off the screen indoors, he goes to the ...
