Detailed description of the invention
For making the goal of the invention of the present invention, feature, the advantage can be more obvious and understandable, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, and not all embodiments. Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Below a kind of display screen parameter setting method being applied to terminal in the embodiment of the present invention being described, refer to Fig. 1, the display screen parameter setting method in the embodiment of the present invention includes:
101, terminal has detected whether that storage card inserts;
In the embodiment of the present invention, terminal comprises memory card interface, and storage card can access this terminal by this memory card interface of insertion.
Concrete, the storage card in the embodiment of the present invention can be USB flash disk, safe digital (SD, SecureDigital) card, multimedia card (MMC, MultimediaCard) or other storage card, is not construed as limiting herein.
When terminal has detected that storage card inserts, perform step 102.
When terminal be not detected by storage card insert time, return and perform step 101, or, it is also possible to terminate this flow process immediately or when Preset Time arrives or during predeterminable event triggering.
102, said memory card is detected;
When terminal has detected that storage card inserts, said memory card being detected, detection process can include storage card is detected totally, or, it is also possible to only the one or more assigned catalogues in storage card are detected, be not construed as limiting herein.
Optionally, whether terminal detection said memory card comprises with the file of preset format name, when detecting the file comprised in said memory card with preset format name, this document is defined as screen ginseng file; When detecting, said memory card does not comprise the above-mentioned file with preset format name, it is determined that said memory card does not comprise screen ginseng file. Specifically, set one or more assigned catalogues (such as root) in storage card to be used for storing screen ginseng file, then in step 102, terminal only need to detect whether the assigned catalogue in this storage card comprises with the file of preset format name, when assigned catalogue comprising with the file of preset format name, then this document is defined as screen ginseng file, when assigned catalogue not comprising with the file of preset format name, it is determined that said memory card does not comprise screen ginseng file.
It should be noted that the screen ginseng file in the embodiment of the present invention refers to the file comprising display screen parameter information.
If 103 detect that said memory card comprises screen ginseng file, then, above-mentioned screen is joined file and writes the specified partition of above-mentioned terminal;
Such as, when the operating system of terminal is android system (Chinese is translated into Android system) or other system based on linux kernel, above-mentioned specified partition can be MISC subregion, wherein, MISC subregion is an important subregion of android system, and this subregion comprises various system and arranges, for instance switch at the ON/OFF of form, USB (universal serial bus) (USB, UniversalSerialBus) configuration and some hardware setting etc. Certainly, above-mentioned specified partition can also be other subregion, is not construed as limiting herein.
104, above-mentioned terminal is restarted;
In the embodiment of the present invention, resetted automatically above-mentioned terminal after step 103 performs by Script controlling, it is of course also possible to performed to export afterwards prompting message in step 103, reminding user to restart above-mentioned terminal, the mode restarting terminal is not defined by the embodiment of the present invention.
105, above-mentioned terminal startup stage, terminal obtain from above-mentioned specified partition above-mentioned screen ginseng file;
It should be noted that above-mentioned startup stage refer to that terminal starts to start and be not fully complete stage of startup.
Such as, when the operating system of terminal is android system or other system based on linux kernel, the startup stage of referring to uboot above-mentioned startup stage.
106, the display screen parameter information of current above-mentioned terminal is obtained;
Such as, when the operating system of terminal is android system or other system based on linux kernel, terminal can obtain the display screen parameter information of current above-mentioned terminal from the bootargs environmental variable of terminal.
If the display screen parameter information in 107 above-mentioned screen ginseng files is inconsistent with the display screen parameter information of current above-mentioned terminal, then imports above-mentioned screen ginseng file, update the display screen parameter of above-mentioned terminal.
In the embodiment of the present invention, import above-mentioned screen ginseng file refer in the environmental variable that the display screen parameter information write being joined by screen in file is relevant to the display screen parameter of terminal and preserve, then after terminal completes startup, namely achieve the renewal of the display screen parameter to terminal.
When the operating system of terminal is android system or other system based on linux kernel, then the display screen parameter information of above-mentioned screen ginseng file is specifically write in bootargs environmental variable and preserves by step 107, to realize the renewal of the display screen parameter to terminal.
Further, the embodiment of the present invention can also store system upgrade bag and/or medium access control (MAC in said memory card, MediaAccessControl) address, then in a step 102, when this AKU being detected, system is updated upgrading according to this AKU by terminal, and when this MAC Address being detected, local MAC Address is updated by terminal according to this MAC Address.
It should be noted that in the embodiment of the present invention terminal can be intelligent television, advertisement machine or other there is the terminal of display screen, the operating system of terminal can be android system, naturally it is also possible to for other type of operating system.
