Fig. 1 is the method flow diagram of the switching display that illustrates according to one embodiment of the invention.Please refer to Fig. 1, at first, in step S105, electronic installation receives switching command, switches to another display with the display from present use.For example, be provided with one group of quick functional key in the electronic installation and come switching display.After user's activation quick functional key, electronic installation just can receive switching command by quick functional key, comes switching display with the foundation switching command.
With notebook computer, originally can be provided with a LCD in the notebook computer.And TV terminal, S video (S-Video) terminal, digital visual interface (DigitalVideo Interface can be set in addition usually in notebook computer; DVI) terminal, high-res multimedia interface (High Definition MultimediaInterface; HDMI) linkage unit such as terminal or D-sub terminal; to connect other external displays (for example, TV, projector, CRT or other LCD etc.).In addition, more be provided with one group of quick functional key (for example " Fn " with " F4 ") on the notebook computer, between the LCD of this machine and external display, switch for the user.
Then, in step S110, before switching, electronic installation can be recorded to the resolution of present employed display (for example this machine display) in the data bank (for example being configuration files or archives) of electronic installation.
In the present embodiment, be provided with a data bank in the electronic installation, be used for storing the resolution of each display.Comprise a plurality of fields in this data bank, write down the resolution of each display to utilize these fields.Electronic installation is after receiving switching command, and before switching to another display from present employed display, electronic installation can be recorded to the resolution of present employed display in the corresponding field.
For instance, in the present embodiment, respectively corresponding each linkage unit of each field, the linkage unit that is coupled with the foundation display comes the resolution of record display device to corresponding field.That is to say that a linkage unit writes down one group of resolution.And in other embodiments, each field more can be distinguished corresponding each display, is recorded in its corresponding field with the resolution with each display.In other words, a display writes down one group of resolution.
When the resolution of record display device is to data bank, whether there has been the resolution of this display in can first inspection of data storehouse.When having had the resolution of this display in the data bank, judge whether that again the resolution of display use at present is identical therewith, with updatedb when both are inequality.On the other hand, when not having the resolution of this display as yet in the data bank, then the resolution that this display is used at present writes in the data bank.
Afterwards, in step S115, electronic installation switches to another display.At this, electronic installation can receive resolution adjustment instruction, to adjust the resolution of the present employed display of electronic installation.The user can adjust the resolution of display according to hobby.
Then, in step S120, electronic installation receives switching command once more, to switch back previous display.For instance, when the user after this machine display switches to one of them external display, desire again when one of them external display switches back this machine display, the user can be switched back this machine display by quick functional key once more.At this moment, electronic installation more can be recorded to the resolution of present employed external display in the data bank.
At last, shown in step S125, when electronic installation switches back previous display, take out corresponding resolution from data bank, so that this resolution is applied mechanically to previous employed display.
To switch back this machine display from external display is example.When taking out the resolution of this machine display correspondence from data bank, whether the resolution that can compare in the data bank is identical with the resolution of external display.If both are identical, the resolution of directly applying mechanically external display is this machine display so far.Otherwise, if both are inequality, then to reset this machine display from the resolution that data bank was captured.
Lift an example again and illustrate, switching to external CRT with notebook computer from the LCD of this machine is example.Suppose that LCD resolution originally is set at 1024 * 768.Before switching to CRT, earlier resolution 1024 * 768 is recorded in the data bank.Then, after switching to CRT and when switching back LCD once more, take out the resolution 1024 * 768 of precedence record from data bank.Afterwards, whether the resolution of the LCD that is relatively write down is identical with the resolution of CRT.If both are identical, the resolution of then applying mechanically CRT gets final product; If both are inequality, then the resolution with LCD reverts to the resolution 1024 * 768 that is write down.
Each step of method of switching display of the present invention below is described for an embodiment more in detail.Fig. 2 is the method flow diagram of the switching display that illustrates according to another embodiment of the present invention.Please refer to Fig. 2, at first, in step S205, electronic installation receives switching command.At this, switching command is to use from first display to switch to second display.

In step S215, electronic installation can be before switching to second display, and the resolution of first display is recorded in the data bank.In the present embodiment, electronic installation is the linkage unit that is coupled according to first display, and its resolution is recorded to field corresponding in the data bank.Then, shown in step S220, electronic installation switches to second display.
Afterwards, in step S225, electronic installation can be judged the resolution that whether has second display in the data bank.If exist, then execution in step S230; On the contrary, if do not exist, execution in step S235 then, electronic installation is directly applied mechanically the resolution of first display.
In step S235, because there is not any value as yet in the field of the linkage unit correspondence that second display is coupled in the data bank, electronic installation is just directly applied mechanically the resolution of the display (i.e. first display) of previous use.Afterwards, determine whether to readjust resolution by the user again.
Return step S225, when having the resolution of second display in the data bank, shown in step S230, electronic installation takes out the resolution of the second display precedence record in data bank.Then, in step S240, the resolution in the electronic installation comparison data bank and the resolution of first display.When both were identical, shown in step S235, the resolution that electronic installation is directly applied mechanically first display got final product.On the other hand, when both were inequality, shown in step S245, electronic installation reverted to the resolution of precedence record in data bank with second display.
For instance, when the user utilizes quick functional key to come switching display, the quick functional key corresponding application program will be received switching command.Afterwards, by application program calculate in advance switch before the resolution of display, and this resolution is recorded among the configuration files.The order that display switches for example is LCD, CRT, external TV, HDMI etc.
When switching, owing to noted the resolution of each display, therefore when switching back original display, promptly can read the existing resolution of configuration files and display and compare.If write down differently as existing resolution of display and configuration files, then recover the individualized resolution of corresponding display, set action otherwise then can omit.
In addition, in other embodiments, can omit above-mentioned steps S240.Just no matter whether the resolution that write down is identical with the resolution of first display in the data bank, the resolution that electronic installation directly reverts in the data bank to be write down.In addition, in other embodiments, also can in data bank, store the corresponding resolution of each display (or linkage unit) in advance, thereby omit above-mentioned steps S225.
In sum, in the above-described embodiments since at switching display to another display, all can note current resolution earlier to data bank.Afterwards, when switching back, just can in data bank, take out corresponding resolution, and need not reset.In view of the above, solving the user needs after switching, constantly sets the individualized resolution of existing or identical display.
