All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a method for setting parameters of a display screen applied to a terminal in an embodiment of the present invention is described below, where the method for setting parameters of a display screen in an embodiment of the present invention includes:
101. the terminal detects whether a memory card is inserted;
in the embodiment of the invention, the terminal comprises a memory card interface, and the memory card can be inserted into the terminal through the memory card interface.
Specifically, the memory Card in the embodiment of the present invention may be a usb disk, a Secure Digital (SD) Card, a Multimedia Card (MMC), or other memory cards, which is not limited herein.
When the terminal detects that a memory card is inserted, step 102 is executed.
When the terminal does not detect that the memory card is inserted, the process returns to step 101, or the process may be ended immediately or when a preset time is reached or a preset event is triggered.
102. Detecting the memory card;
when the terminal detects that the memory card is inserted, the memory card is detected, and the detection process may include detecting the memory card in a full disk, or may also detect only one or more specified directories in the memory card, which is not limited herein.
Optionally, the terminal detects whether the memory card contains a file named in a preset format, and determines the file as a screen parameter file when detecting that the memory card contains the file named in the preset format; and when the memory card is detected not to contain the file named in the preset format, determining that the memory card does not contain the screen parameter file. Specifically, one or more designated directories (e.g., root directories) in the memory card are set to store the screen parameter file, in step 102, the terminal only needs to detect whether the designated directories in the memory card include the file named in the preset format, determine the file as the screen parameter file when the designated directories include the file named in the preset format, and determine that the memory card does not include the screen parameter file when the designated directories do not include the file named in the preset format.
It should be noted that the screen parameter file in the embodiment of the present invention refers to a file containing display screen parameter information.
103. If the memory card is detected to contain the screen parameter file, writing the screen parameter file into the appointed subarea of the terminal;
for example, when the operating system of the terminal is an Android system (chinese is translated into an Android system) or other linux kernel-based system, the designated partition may be a MISC partition, where the MISC partition is an important partition of the Android system, and the partition contains various system settings, such as ON/OFF switches in the form, Universal Serial Bus (USB) configuration, some hardware settings, and the like. Of course, the designated partition may be other partitions, and is not limited herein.
104. Restarting the terminal;
in the embodiment of the present invention, the terminal is automatically restarted after the step 103 is executed through script control, and of course, a reminding message may be output after the step 103 is executed, so as to remind the user to restart the terminal.
105. In the starting stage of the terminal, the terminal acquires the screen parameter file from the designated partition;
the start-up phase is a phase in which the terminal starts to start and does not complete the start-up.
For example, when the operating system of the terminal is an Android system or other linux kernel-based system, the above boot phase refers to an uboot boot phase.
106. Acquiring the current display screen parameter information of the terminal;
for example, when the operating system of the terminal is an Android system or other linux kernel-based system, the terminal may obtain current display screen parameter information of the terminal from bootarms environment variables of the terminal.
107. And if the display screen parameter information in the screen parameter file is inconsistent with the current display screen parameter information of the terminal, importing the screen parameter file and updating the display screen parameter of the terminal.
In the embodiment of the invention, the step of importing the screen parameter file refers to the step of writing the display screen parameter information in the screen parameter file into the environment variable related to the display screen parameter of the terminal and storing the display screen parameter information, so that the display screen parameter of the terminal is updated after the terminal is started.
When the operating system of the terminal is an Android system or other linux kernel-based system, step 107 specifically writes the display screen parameter information of the screen parameter file into bootargs environment variables and stores the display screen parameter information so as to update the display screen parameters of the terminal.
Further, in this embodiment of the present invention, a system upgrade package and/or a Media Access Control (MAC) address may also be stored in the memory card, in step 102, when the upgrade package is detected, the terminal updates and upgrades the system according to the upgrade package, and when the MAC address is detected, the terminal updates a local MAC address according to the MAC address.
It should be noted that, in the embodiment of the present invention, the terminal may be a smart television, an advertisement player, or another terminal having a display screen, and an operating system of the terminal may be an Android system, but may also be other types of operating systems. The display screen in the embodiment of the present invention may be an LCD, or may also be other display screens that require parameter configuration, which is not limited herein.
