Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for controlling backlight brightness of a display screen of a mobile terminal according to a preferred embodiment of the present invention. As shown in fig. 1, the method for controlling backlight brightness of a display screen based on a mobile terminal according to an embodiment of the present invention includes:
and step S100, setting corresponding display brightness control files for each application program of the mobile terminal in advance and storing the files.
For example, a user sets a plurality of application programs in advance as implementation objects of the technical solution of the present invention. Specifically, considering that the display color of the electronic book is single when the electronic book is read, each display interface is ground color and font color under different display conditions, the display content difference is low, and the method is suitable for the method, and if the user selects the electronic book reader, the technical scheme of the method is implemented for the electronic book reader; as for the chat software, the display color is relatively single in the chat process, and each display interface is the background color and the font color under different display conditions, and may also have the avatar color and the like, which is also relatively suitable for the invention.
And setting a display brightness control file corresponding to each application program, opening the corresponding application program during specific setting, then adjusting the display brightness to a proper value, and then saving the display brightness control file corresponding to the application program.
Step S200, when the mobile terminal opens one of the plurality of application programs, searching whether a display brightness control file of the application program exists, if so, executing step S300, and if not, executing step S400;
specifically, when a user opens an application program, whether the application program is a corresponding display brightness control file preset by the user is judged; and searching whether a display brightness control file of the application program exists or not, if so, executing the step S300, and if not, executing the step S400.
The brightness control file is used for controlling the brightness of the display screen, wherein the actual set brightness corresponding to various brightness values set by a user is recorded in the brightness control file; for example, the brightness of the mobile terminal on the user interface is set to be 0-9, which is ten levels, however, for different applications, due to different display interface colors, the brightness of the mobile terminal at the same level is set to be different from the brightness of the mobile terminal actually perceived by people, and similarly, the brightness of the mobile terminal is set to be 6, the first electronic book application of the black-in-white characters appears brighter than the second electronic book application of the white-in-black characters, at this time, if the user sets the backlight brightness to be 3 when opening the first electronic book application, and sets the backlight brightness to be 9 when opening the second electronic book application, the two applications seem to perceive brightness to be almost the same. The brightness control file is a file recorded with the corresponding relation, the brightness of the mobile terminal on the user interface is set to be 0-9 levels of brightness, one brightness control file is used for each application preset by the user, and the brightness actually set by the user when the user sets 0-9 levels of brightness on the user interface is recorded in the brightness control file.
Step S300, acquiring the display brightness L1 of a display brightness control file corresponding to the currently opened application program, searching an actual set brightness value L2 corresponding to the brightness value in the brightness control file, and setting the brightness value to be L2;
for example, when the backlight brightness set by the current mobile terminal is 6, at this time, the user opens an application, and when the brightness control file of the application indicates that the backlight brightness is 7, which corresponds to the backlight brightness that should be set actually when the backlight brightness is 6, the backlight brightness is set to 7; and then if the user adjusts the backlight brightness to be 8 under the application, and the backlight brightness which is actually set when the backlight brightness is 8 is indicated to be 9 in the brightness control file of the application, the backlight brightness is set to be 9. Thereby making the user comfortable to see.
And S400, automatically setting the brightness of each display screen by the mobile terminal, prompting to input the proper display screen set brightness under each brightness, and recording the brightness control file corresponding to the application program and storing the brightness control file after the operation is finished.
Specifically, when an application does not have a corresponding brightness control file, the mobile terminal sets the brightness of each range from 0 to 9 when the application is printed, prompts the user to input the brightness value which is considered to be suitable by the user when the brightness of each range is set, and then records the brightness which is considered to be suitable by the user when the brightness of the application is set to be the brightness control file of the application and stores the brightness control file of the application.
It can be seen that, when the user opens one of the plurality of application programs, the method of the present invention firstly searches whether there is a display brightness control file of the application program, if so, obtains the display brightness L1 set by the current user, searches the actual set brightness value L2 corresponding to the brightness value in the brightness control file, and then sets the brightness value to L2; if not, the mobile terminal automatically sets the brightness of each display screen, prompts the user to input the display screen setting brightness suitable under each brightness, and records the display screen setting brightness as the brightness control file of the application program after the user finishes the operation. Aiming at the application program of the implementation object of the invention preset by the user, the mobile terminal can automatically set the corresponding brightness according to the display content under different display interfaces, so that the mobile terminal is beneficial to the user to watch, thereby providing convenience for the user and improving the user experience.
Based on the above method embodiment, the present invention further provides a display screen backlight brightness control system based on a mobile terminal, as shown in fig. 2, the system includes:
the judging module 210: when the mobile terminal opens one of the plurality of application programs, searching whether a display brightness control file of the application program exists or not; as described above.
The brightness reset module 220: the method comprises the steps of obtaining display brightness L1 of a display brightness control file corresponding to a currently opened application program, searching an actual set brightness value L2 corresponding to the brightness value in the brightness control file, and setting the brightness value to be L2; as described above.
