For example, when each subordinate electronic equipment sends positional information to described host electronic equipment, also can initiatively send the second size of the described second display screen that self comprises to described host electronic equipment, thereby make described host electronic equipment know the second size of described second display screen; Perhaps, described host electronic equipment can send the size request message to each subordinate electronic equipment, obtains the second size of described second display screen with request; Perhaps, described host electronic equipment can be set up a coordinate system, for example, shown in Fig. 2 A, be the schematic diagram of three electronic equipments when splicing, wherein label is that 1 electronic equipment can be called the first electronic equipment, label is that 2 electronic equipment can be called the second electronic equipment, label is that 3 electronic equipment can be called the 3rd electronic equipment, and described the first electronic equipment can be host electronic equipment, and described the second electronic equipment and described the 3rd electronic equipment can be the subordinate electronic equipments.Wherein, the first electronic equipment described in Fig. 2 A is identical with the size of described the second electronic equipment.Rectangle frame wherein is illustrated as display screen.For example, described the first electronic equipment can be set up a coordinate system, its true origin can be the interior any point of self range of control, for example selecting the top left corner apex of described the first display screen in the embodiment of the invention is true origin, then described the first electronic equipment not only can directly determine that according to this coordinate system at least one coupled subordinate electronic equipment with respect to the position relationship of self, can also obtain the size of described the first display screen of self, the size of described the 3rd display screen of the size of the described second display screen of described the second electronic equipment and described the 3rd electronic equipment.

Step 103: determine a viewing area according to described position relationship information, described first size and described the second size, wherein, described viewing area is made of described first display screen of described first size and the described second display screen of described the second size.

According to position relationship information, described first size and described the second size determined, can determine a viewing area.Described viewing area can be comprised of the display screen of each electronic equipment.For example, described viewing area among Fig. 2 A is that the described second display screen by described second size of the described second display screen of described second size of described first display screen of the described first size of described the first electronic equipment, described the second electronic equipment and described the 3rd electronic equipment is consisted of, described viewing area can be regular figure or irregular figure, and the described viewing area among Fig. 2 A then is irregular figure.

When with described at least one subordinate electronic equipment of described host electronic equipment splicing in have the position of arbitrary subordinate electronic equipment to change, or the position of described host electronic equipment changes, and regained in described at least one subordinate electronic equipment each subordinate electronic equipment and then can determine a viewing area according to the described position relationship information that regains, described first size and described the second size with respect to the position relationship information of described host electronic equipment.When the position that electronic equipment is arranged changed, the shape of the described viewing area of determining when the shape of definite described viewing area may not change from the position was different.

Step 104: determine the first effective display area territory of described the first display screen and the second effective display area territory of described second display screen according to predetermined condition, wherein, described the first effective display area territory and described the second effective display area territory consist of the effective display area territory in the described viewing area.

Described predetermined condition can be to determine longest edge and the broadside of described viewing area, determines a regular figure according to described longest edge or described broadside.The zone that this regular figure covers is described effective display area territory, this effective display area territory can comprise described the first effective display area territory and/or the second effective display area territory, for example, electronic equipment splicing schematic diagram shown in Fig. 2 A, if the broadside according to described viewing area is determined a regular figure, then can not comprise the described second effective display area territory of described the 3rd electronic equipment in this regular figure.

The mode of determining described longest edge and broadside in the embodiment of the invention can be: described host electronic equipment can be set up a coordinate system, described host electronic equipment can obtain spliced electronic equipment in the longest distance of X-direction, and spliced electronic equipment is in the longest distance of Y direction, longest distance in X-direction namely can be described longest edge, namely can be described broadside in the longest distance of Y direction.

At first can determine according to described first size and described the second size at least one effectively long limit and at least one effective broadside of described viewing area.For example, three electronic equipments shown in Fig. 2 A, can determine the first effective edge according to the long limit of described the first electronic equipment and the broadside of described the 3rd electronic equipment, can determine the second effective edge according to the broadside of described the first electronic equipment and the broadside of described the second electronic equipment, can determine the 3rd effective edge according to the long limit of described the 3rd electronic equipment, can also determine the 4th effective edge according to the long limit of described the first electronic equipment or the long limit of described the second electronic equipment.Because the complete parallel aligned of described the first electronic equipment and described the second electronic equipment is arranged, the effective edge of therefore determining according to the broadside of the long limit of described the second electronic equipment and described the 3rd electronic equipment is identical with described the first effective edge length.Described the first effective edge and described the 4th effective edge are long limit, can determine that described the first effective edge is the longest edge of described viewing area, described the second effective edge and described the 3rd effective edge are broadside, can determine that described the second effective edge is the broadside of described viewing area.

Continuation describes as an example of Fig. 2 A example, can determine different described effective display area territories according to the longest edge of the described viewing area of determining or the broadside in described effective display area territory.

For example, if take the longest edge of described viewing area as benchmark, can determine that then described the first effective edge is the long limit in described effective display area territory, described the 3rd effective edge is the broadside in described effective display area territory, shown in Fig. 2 B, the part that dotted line surrounds among Fig. 2 B is described effective display area territory; If take the broadside of described viewing area as benchmark, can determine that then described the second effective edge is the broadside in described effective display area territory, described the 4th effective edge is the long limit in described effective display area territory, and shown in Fig. 2 C, the part that dotted line surrounds among Fig. 2 C is described effective display area territory.

Continuation describes as an example of Fig. 2 A example, perhaps, can determine respectively different described effective display area territories according to described the first effective edge of determining, described the second effective edge, described the 3rd effective edge and described the 4th effective edge.For example:

If be as the criterion to determine described effective display area territory with described the first display screen, can determine that then described the first effective edge is the effective long limit in described effective display area territory, described the 3rd effective edge is effective broadside in described effective display area territory, can determine that perhaps described the 4th effective edge is the effective long limit in described effective display area territory, described the second effective edge is effective broadside in described effective display area territory.

If the described second display screen with described the second electronic equipment is as the criterion to determine described effective display area territory, can determine that then described the first effective edge is the effective long limit in described effective display area territory, described the 3rd effective edge is effective broadside in described effective display area territory, can determine that perhaps described the 4th effective edge is the effective long limit in described effective display area territory, described the second effective edge is effective broadside in described effective display area territory.

If the described second display screen with described the 3rd electronic equipment is as the criterion to determine described effective display area territory, can determine that then described the first effective edge is the effective long limit in described effective display area territory, described the 3rd effective edge is effective broadside in described effective display area territory.

The mode of determining described effective display area territory can have multiple, the described effective display area territory of determining also can be different, the user can select according to actual needs, selecting different described effective display area territories according to difference Properties of Objects to be shown, obtains best display effect.

After determining described effective display area territory, described the first display screen shows all objects in described the first effective display area territory, and described second display screen shows all objects in described the second effective display area territory.For example, shown in Fig. 2 A, when definite described the first effective edge is the effective long limit in described effective display area territory, when described the 3rd effective edge is effective broadside in described effective display area territory, some is described the second effective display area territory for the second display screen of described the second electronic equipment, some is the noneffective display area territory, then described the second electronic equipment described the second effective display area territory that can control described second display screen shows all objects, does not show any object and can control another part noneffective display area territory.

Referring to Fig. 3, the present invention also provides a kind of viewing area changing method, and it can be applied to the described host electronic equipment that can link to each other with at least one subordinate electronic equipment, and the specific implementation flow process of described method is as follows:

Step 301: when needs carry out the display mode switching, obtain information to be displayed.

When needs carried out the display mode switching, described host electronic equipment can at first obtain information to be displayed.For example, can carry out display mode according to user's indication and switch, perhaps system can determine that automatically needs carry out display mode and switch according to the characteristic of information to be displayed.

Step 302: when linking to each other with described at least one subordinate electronic equipment, judge except current display mode, whether there are at least a other display modes.

Finish in a plurality of electronic equipment splicings, and after determining described effective display area territory, every kind of described effective display area territory can represent a kind of display mode, can switch between the different display modes, if determined at least one different effective display area territory, then can determine to exist at least a display mode.

Step 303: when judged result when being, switch to a kind of display mode in described other display modes.

If judge and determine except current display mode, not have other display modes, then can not carry out blocked operation.Determine except current display mode, to exist other display modes if judge, then can indicate according to the user and select required display mode in described other display modes, perhaps also can automatically select display mode required in other display modes according to the characteristic of information to be displayed.And, if judge in definite other display modes there is not suitable display mode, can not switch yet.

For example determine except current display mode, to exist other display modes in the embodiment of the invention.For example, be the effective long limit in described effective display area territory if determine described the first effective edge, described the 3rd effective edge is effective broadside in described effective display area territory, then described effective display area territory can be called the 3rd effective display area territory; If determining described the 4th effective edge is the effective long limit in described effective display area territory, described the second effective edge is effective broadside in described effective display area territory, and then described effective display area territory can be called the 4th effective display area territory; If determine the broadside that described the second effective edge is described effective display area territory, described the 4th effective edge is the long limit in described effective display area territory, and then described effective display area territory can be called the 5th effective display area territory, etc.

For example, current display mode is the second display mode, and it is corresponding to described the 4th effective display area territory.And object to be shown is a video, it relatively is fit to widescreen and watches, can obtain better viewing experience, and described the 3rd effective display area territory is the widescreen zone, it is corresponding to the first display mode, then can select described the first effective edge is the effective long limit in described effective display area territory, described the 3rd effective edge is effective broadside in described effective display area territory, determine that namely described effective display area territory is described the 3rd effective display area territory, switches to described the first display mode from current described the second display mode and shows.

For example, current display mode is described the first display mode, and it is corresponding to described the 3rd effective display area territory.Object to be shown is a video, its suitable widescreen is watched, can obtain better viewing experience, described host electronic equipment indicates to judge whether there are at least a other display modes except current display mode according to the user, judged result is yes, and user's original idea is in order to seek the effective display area territory wider than the width in described the 3rd effective display area territory, described host electronic equipment can know that the width in described the 3rd effective display area territory has been the widest in all described effective display area territories, then can continue to switch or do not switch according to user's indication, perhaps described host electronic equipment can directly be determined not switch.

If it is touch-screen that the display screen of electronic equipment is arranged, for example, described first display screen of the first electronic equipment described in Fig. 2 A is touch-screen, when then the user operated described the first display screen by finger or other operating bodies, described the first electronic equipment can directly respond according to this operation.For example, the user has drawn a circle by finger at described the first display screen, and then described the first electronic equipment responds this operation, directly circle of relevant position demonstration on described the first display screen.If the described second display screen of the second electronic equipment described in Fig. 2 A is touch-screen, when then the user operates described second display screen by finger or other operating bodies, described the second electronic equipment can directly respond according to this operation, perhaps, described the second electronic equipment can send message to described the first electronic equipment after accepting this operation, carry out respective response by described the first electronic equipment, and response results can be transferred to described the second electronic equipment.For example, the user has drawn a circle by finger at described second display screen, described the second electronic equipment can directly respond this operation, can be directly on described the first display screen the relevant position show a circle, perhaps, described the second electronic equipment can be sent to described the first electronic equipment with the information that the user has carried out this operation in the mode that sends message or instruction, described the first electronic equipment can operate according to the message or the instruction that receive, determine first content (i.e. circle), and described first content is sent to described the second electronic equipment, make described second display screen show, perhaps, described the first electronic equipment can indicate described the second electronic equipment to carry out corresponding operating, generates and shows described first content.

If described the first display screen and described second display screen are touch-screen, when described second display screen receives the first operation, described the first operation is responded, produce a response results, described host electronic equipment carries out corresponding operating according to described response results.

For example, when having a plurality of electronic equipments to splice, the user selectes an object on an electronic equipment therein, operate on it, for example this object is a picture of the described second display screen demonstration of described the second electronic equipment, the user carries out amplifieroperation to it on described second display screen, described the second electronic equipment responds this amplifieroperation, described picture is amplified, when the user continues to amplify to this picture, when its indication range has been touched the effective display area territory of other electronic equipments, other electronic equipments respond this amplifieroperation, produce a response results, each electronic equipment all is sent to response results described host electronic equipment, the information that described host electronic equipment need show each electronic equipment according to each response results is sent to each electronic equipment, display screen for each electronic equipment shows, thereby the image after a plurality of demonstration screen displays are amplified, perhaps described host electronic equipment can send indication to each subordinate electronic equipment respectively after receiving each response results, to indicate each subordinate electronic equipment to show corresponding contents, the display screen of each electronic equipment is according to the indicated number corresponding contents, so that a plurality of display screen shows the image after amplifying.

For example, when having a plurality of electronic equipments to splice, the common object that shows of a plurality of display screens, the user operates this object, for example this object is a picture, the user carries out reduction operation to it, the user can carry out reduction operation to it by finger, spliced each electronic equipment schematic diagram is take Fig. 2 A as example, user's finger may streak the display screen of three electronic equipments, then each electronic equipment can respond corresponding operating, and response results is sent to described host electronic equipment, described host electronic equipment can be determined indication range after this picture dwindles according to each response results, for example, after dwindling, this picture only needs to show at the described second display screen of described the second electronic equipment, then described host electronic equipment information that described the second electronic equipment need be shown is sent to described the second electronic equipment, second display screen for described the second electronic equipment shows, thereby the image after the described second display screen demonstration of described the second electronic equipment is dwindled, perhaps described host electronic equipment can be determined the indication range after this picture dwindles after receiving each response results, for example, after dwindling, this picture only needs to show at the described second display screen of described the second electronic equipment, then described host electronic equipment sends indication to described the second electronic equipment, to indicate described the second electronic equipment to show corresponding contents, the second display screen of described the second electronic equipment is according to the indicated number corresponding contents.

For example, when having a plurality of electronic equipments to splice, the user selectes an object on an electronic equipment therein, it can be moved on another electronic equipment, shows at another electronic equipment.For example, if the display screen of each electronic equipment is touch-screen, the user can slide at Mosaic screen with finger behind a selected object, and system is synchronized to another electronic equipment with selected object from an electronic equipment automatically.

Describe as an example of Fig. 2 A example, the described second display screen of described first display screen of described the first electronic equipment, described the second electronic equipment and the described second display screen of described the 3rd electronic equipment are touch-screen:

For example, the user has selected a file at the described second display screen of the second electronic equipment, for example this document can be the word document, then this document can press...with one's finger, and be slid on the described second display screen of described the 3rd electronic equipment, passed through described first display screen of described the first electronic equipment in sliding process, system is synchronized to described the 3rd electronic equipment with this document, and described the 3rd electronic equipment can obtain this document.

The synchronizing process concrete steps are as follows:
