Referring to FIG. 4, in some embodiments, the system is divided into four layers, from top to bottom, an application layer, a framework layer, a system runtime layer, and a kernel layer, respectively.

In some embodiments, at least one application (e.g., a camera application) is running in the application layer, where the applications may be a Window (Window) program, a system setup program, or a clock program, etc. that is self-contained in the operating system; or may be an application developed by a third party developer.

The display device provided by the embodiment of the application can have various implementation forms, for example, a television, an intelligent television, a laser projection device, a display (monitor), an electronic drawing board (electronic bulletin board), an electronic desktop (electronic table) and the like.

The command input device according to the embodiments of the present application may also have various embodiments according to the specific form of the display, for example, a touch screen pressure sensing device (including but not limited to a pressure sensing device or a capacitance sensing device) disposed on the display screen, a mouse input device, or a remote controller. The communication between the remote controller and the controller comprises at least one of infrared protocol communication or Bluetooth protocol communication and other short-distance communication modes, and communication connection is established between the remote controller and the controller in a wireless or wired mode. The user can input user instructions through at least one of keys on the remote controller, voice input, control panel input and the like.

In some embodiments, the display device 200 may have a touch interaction function, so that a user can operate the host only by lightly touching the display with a finger, and thus, the keyboard, the mouse and the remote controller are eliminated, and the man-machine interaction is more straightforward. Based on the display device 200, the touch component can be added to enable the display device 200 to support the touch interaction function. In general, the touch assembly may together form a touch screen with the display 260. On the touch screen, the user can input different control instructions through touch operation. For example, a user may input touch instructions such as clicking, sliding, long pressing, double clicking, etc., and different touch instructions may represent different control functions.

To implement the different touch actions, the touch assembly may generate different electrical signals when the user inputs the different touch actions, and transmit the generated electrical signals to the controller 250. The controller 250 may perform feature extraction on the received electrical signal to determine a control function to be performed by the user based on the extracted features.

For example, when a user enters a click touch action at any program icon location in the application program interface, the touch component will sense the touch action and thereby generate an electrical signal. After receiving the electrical signal, the controller 250 may determine the duration of the level corresponding to the touch action in the electrical signal, and recognize that the user inputs the click command when the duration is less than the preset time threshold. The controller 250 then extracts the location features generated by the electrical signals to determine the touch location. When the touch position is within the application icon display range, it is determined that a click touch instruction is input by the user at the application icon position. Accordingly, the click touch instruction is used to perform a function of running a corresponding application program in the current scenario, and thus the controller 250 may start running the corresponding application program.

For another example, when the user inputs a sliding motion in the media presentation page, the touch assembly also sends the sensed electrical signal to the controller 250. The controller 250 first determines the duration of the signal corresponding to the touch action in the electrical signal. When the duration time is determined to be longer than the preset time threshold value, the position change condition generated by the signals is judged, and obviously, the generation position of the signals changes for the interactive touch action, so that the user is determined to input a sliding touch instruction. The controller 250 then determines the sliding direction of the sliding touch command according to the change condition of the signal generating position, and controls the page turning of the display screen in the media display page so as to display more media options. Further, the controller 250 may further extract characteristics such as a sliding speed and a sliding distance of the sliding touch instruction, and perform a picture control of turning pages according to the extracted characteristics, so as to achieve a following effect.

Similarly, for the touch instructions such as double-click and long-press, the controller 250 may extract different features, determine the type of the touch instruction through feature judgment, and execute corresponding control functions according to a preset interaction rule. In some embodiments, the touch assembly also supports multi-touch, such that a user may enter touch actions on the touch screen via multiple fingers, e.g., multi-finger clicks, multi-finger long presses, multi-finger swipes, etc.

The touch control action can be matched with a specific application program to realize a specific function. For example, after the user opens the drawing board application, the display 260 may present a drawing area, the user may draw a specific touch action track in the drawing area through the sliding touch instruction, and the controller 250 determines a touch action pattern through the touch action detected by the touch component and controls the display 260 to display in real time, so as to satisfy the demonstration effect.

In some embodiments, multiple applications may be installed in the display device 200, and FIG. 4 illustrates a user interface displayed by the display in some embodiments, where a user may click on "My applications" in the user interface, triggering the display of an application list. All applications that the display device 200 has installed are included in the application list.

Fig. 5 is a schematic rear view of a display device according to some embodiments. As shown in fig. 5, the display device includes a display 260 and a lift driving device 511. The elevation driving apparatus 511 includes an elevation guide rail fixed to the bracket 512. The rotation driving device is then arranged (not shown) inside the elevation driving device, i.e. between the elevation driving device and the display. The display may display images including images from broadcast signals or network signals as described above, and may also include various interactive interface images, such as interfaces for various applications, etc.

In some embodiments, controller 250 controls the operation of display device 200 and responds to user operations associated with display 260 by running various software control programs (e.g., an operating system and/or various application programs) stored on memory. For example, control presents a user interface on a display, the user interface including a number of UI objects thereon; in response to a received user command for a UI object on the user interface, the controller 250 may perform an operation related to the object selected by the user command.

The display device provided by the application has the function of a drawing board. The palette function is implemented based on a palette function related application installed on the display device. For ease of description, the palette function related application will be referred to as a palette application.

In some embodiments, some or all of the steps involved in embodiments of the present application are implemented within an operating system and in an application.

In some embodiments, when a user selects a control, for example, when the user selects split control 740, the electronic palette interface will be divided into at least two regions, i.e., the electronic palette interface presents at least two regions. For clarity of description, the operation principle of the present application will be described hereinafter by taking two drawing board areas as examples. However, it will be appreciated by those skilled in the art that the present application is not so limited and that three or more palette regions may be employed.

Fig. 8 is a split screen interface diagram of an electronic palette in accordance with some embodiments. As shown in fig. 8, the electronic palette interface is divided into a first palette region 810 and a second palette region 820, wherein the first palette region 810 includes a first control region 811 and a first drawing region 812, and the second palette region 820 includes a second control region 821 and a second drawing region 822.

In some embodiments, when the user selects the split screen control 740, the controller controls to determine a first preset area of the first layer as the first drawing area 812, determine a second preset area of the first layer as the second drawing area 822, and refresh the second layer, display controls in the first control area in the first preset area of the second layer, and display controls in the second control area in the second preset area of the second layer. More specifically, the present application is not limited to the positions, sizes and shapes of the first drawing area 812 and the second drawing area 822, and can be set according to the needs.

In some embodiments, as shown in fig. 8, the first control area 811 includes a plurality of controls for editing the first drawing area 812, and the first control area 811 may include at least one of a brush control 813, an erase control 814, a delete control 815, a video control 816, a toolbar control 817, a cancel control 818, and a restore control 819. The second control area 821 includes a plurality of controls for editing the second drawing area 822, and the second control area 821 may include at least one of a brush control 823, an erase control 824, a delete control 825, a video control 826, a toolbar control 827, a cancel control 828, and a restore control 829.

In some embodiments, in response to a user selecting the split screen control 740, the second operation list is controlled to be generated in the memory, and the first operation list is controlled to be used only for storing operation events input in the first drawing area 812 by the user through the control in the first control area 811, to refresh the first layer after the operation events input in the first drawing area 812 by the user through the control in the first control area 811 are stored in the first operation list storage, to display operation contents corresponding to the operation events stored in the first operation list in a first preset area (first drawing area 812) of the first layer, and to store only operation events input in the second drawing area 822 by the user through the control in the second control area 821, to refresh the first layer after the operation events input in the second drawing area 822 by the user through the control in the second control area 821 are stored in the second operation list storage, to display operation contents corresponding to the operation events stored in the second operation list in the second preset area (second drawing area 822) of the first layer.

In some application scenarios, the same user may edit the first drawing area 812 and the second drawing area 822 through the controls in the first control area 811 and the second control area 821, and the same user may also edit the first drawing area 812 and the second drawing area 822 through the controls in the first control area 811 and the second control area 821 at the same time, and further, in the same time, different users may also edit the first drawing area 812 and the second drawing area 822 through the controls in the first control area 811 and the second control area 821.

In some embodiments, when the user selects the brush control 813 of the first control region 811, a brush toolbar 910 corresponding to the brush control 813 may be triggered and displayed, and referring to fig. 9, a brush type, a line color, a line type, a line thickness, and the like may be selected in the brush toolbar 910. The user selects the target type of brush control 813 to pick up the brush and, after picking up the brush, can continue to select the existing line color, line type, line thickness, etc. options in the brush toolbar 910. The line color, line type, and line thickness selected by the user in the brush toolbar 910 are input by the brush control 813 to be configured as the target type. In a state of picking up the brush control 813, the user can input content, i.e., a sliding path of the user on the first drawing region 812, based on contact with the first drawing region 812.

Further, after the user selects parameters such as line color, line type, line thickness, etc. in the drawing toolbar 910, in order not to affect the area where drawing can be performed, the drawing toolbar 910 may be hidden by touching the drawing control 813 to the first drawing area 812, and an electronic drawing board interface after hiding the drawing toolbar 910 is shown in fig. 8.

In some embodiments, after a user leaves a sliding path by contacting with the first drawing area 812, the controller controls to store coordinates of pixels passing through the sliding path into the first operation list, and refreshes the first layer based on the first operation list, so as to fill in colors of pixels corresponding to the coordinates of pixels stored in the memory in a first preset area (the first drawing area 812) of the first layer, thereby displaying the sliding path in the first preset area (the first drawing area 812), and completing drawing of the sliding path.

In some embodiments, when the user selects the brush control 823 of the second control region 821, a brush toolbar 920 corresponding to the brush control 823 may be triggered and displayed, and referring to fig. 9, a brush type, a line color, a line type, a line thickness, and the like may be selected in the brush toolbar 920. The user selects the target type of brush control 823 to pick up the brush, and after picking up the brush, the user may continue to select the existing line color, line type, line thickness, and other options in the brush toolbar 920. The line color, line type, and line thickness selected by the user in the brush toolbar 920 are input by the brush control 813 to be configured as the target type. In a state of picking up the brush control 823, the user may input content, i.e., a sliding path of the user on the second drawing area 822, based on contact with the second drawing area 822.

Further, after the user selects parameters such as line color, line type, line thickness, etc. in the drawing toolbar 920, in order not to affect the area where drawing can be performed, the drawing toolbar 920 may be hidden by touching the drawing control 823 with the second drawing area 822, and an electronic drawing board interface after hiding the drawing toolbar 920 is shown in fig. 8.

In some embodiments, after a user leaves a sliding path by contacting with the second drawing area 822, the controller controls to store coordinates of pixels passing through the sliding path into the second operation list, and refreshes the first layer based on the second operation list, so as to fill in colors of pixels corresponding to the coordinates of pixels stored in the memory in a second preset area (the second drawing area 822) of the first layer, thereby displaying the sliding path in the second preset area (the second drawing area 822), and completing drawing of the sliding path.

In some embodiments, the user may begin drawing after configuring parameters of the brush control. Because the second layers to which the first control area 811 and the second control area 821 belong are suspended above the first layers to which the first drawing area 812 and the second drawing area 822 belong, when a user picks up the brush control to start drawing, the second layers receive the sliding operation from the drawing start point to the drawing end point input by the user before the first layers. When the second image layer receives a sliding track corresponding to a sliding operation from a drawing starting point to a drawing end point, which is input by a user, the controller controls to store pixel point coordinates passed by the sliding path into a first operation list, determines a target area according to the pixel point coordinates corresponding to the drawing starting point, wherein the target area is a drawing area where the drawing starting point is located, and refreshes the first image layer according to a drawing parameter indicated by a first drawing control and the first operation list stored in the memory if the drawing starting point belongs to the first drawing area 812, and performs color filling or replacement on the pixel points passed by the sliding path in the first drawing area. If the drawing starting point belongs to the second drawing area 822, the first layer is refreshed according to the drawing parameters indicated by the second drawing control and the second operation list stored in the memory, and color filling or replacement is performed on the pixel points passing through the sliding path in the second drawing area 822.

For example, after the brush parameters of the brush control 813 and the brush control 823 are configured respectively, if the drawing start point is in the first drawing area 812, the controller will read the brush parameters of the brush control 813, at this time, the brush control 813 is in a pickup state, if the user continues to utilize the brush control 813 to move in a touch manner on the electronic drawing board, all the pixel points on the touch movement track located in the first drawing area 812 will be filled according to the brush parameters of the brush control 813, and all the pixel points on the touch movement track located in the second drawing area 822 will not be filled. Or if the drawing starting point is in the second drawing area 822, the controller reads the brush parameters of the brush control 823, at this time, the brush control 823 is in a pick-up state, and if the user continues to utilize the brush control 823 to move in a touch manner on the electronic drawing board, all pixel points on the touch movement track, which are positioned on the second drawing area 822, are filled according to the brush parameters of the brush control 823, and all pixel points on the touch movement track, which are positioned on the first drawing area 812, are not filled.

In some embodiments, the contents in the first drawing area 812 and/or the second drawing area 822 may be erased by an eraser control, specifically, the controller determines an erasing path from the erasing start point to the erasing end point in response to a sliding operation from the erasing start point to the erasing end point input by a user, and acquires a target drawing area according to coordinates of a pixel point where the erasing start point is located, where the target drawing area is the drawing area where the erasing start point is located; if the target drawing area is the first drawing area 812, storing the coordinates of the pixel points passing through the erasing path into a first operation list, refreshing the first image layer according to the coordinates of the pixel points passing through the erasing path stored in the first operation list, and eliminating or replacing the color of the pixel points passing through the erasing path in the first image layer to erase the historical drawing track which is overlapped with the erasing path in the first drawing area 812, namely eliminating or replacing the color of the pixel points passing through the historical drawing track which is overlapped with the erasing path in the first drawing area 812; if the target drawing area is the second drawing area 822, storing the coordinates of the pixel points passing through the erasing path into a second operation list, refreshing the first layer according to the coordinates of the pixel points passing through the erasing path stored in the second operation list, and eliminating or replacing the color of the pixel points passing through the erasing path in the first layer to erase the historical drawing track which coincides with the erasing path in the second drawing area 822, namely eliminating or replacing the color of the pixel points passing through the historical drawing track which coincides with the erasing path in the second drawing area 822.

It should be noted that, the eraser control 814 in the first control area 811 can only delete the content in the first drawing area 812, and the eraser control 824 in the second control area 821 can only delete the content in the second drawing area 822. That is, when the drawing start point of the user belongs to the first drawing area 812, the eraser control 814 is in a pickup state, and the user deletes the content on the touch movement track of the eraser control 814 by moving the eraser control 814, even if the touch movement track of the eraser control 814 is partially on the second drawing area 822, the content in the second drawing area 822 is not deleted. Similarly, when the drop point of the user belongs to the second drawing area 822, the eraser control 824 is in a pickup state, and the user moves the eraser control 824 to delete the content on the touch movement track of the eraser control 824, even if some of the touch movement track of the eraser control 824 is on the second drawing area 822, the content in the second drawing area 822 is not deleted.

In some embodiments, the entire content in the first drawing area 812 may be deleted by selecting the delete control 815 in the first control area 811. For example, when the user selects the delete control 815, a selection interface as shown in fig. 8 is triggered, which includes a confirm option and a cancel option, and when the user selects the confirm option, the entire contents in the first drawing area 812 are deleted, while the entire contents in the second drawing area 822 are still reserved, as shown in fig. 11.

In some embodiments, in response to selection of the delete control 815 in the first control region 811, deleting the operation content stored in the first operation list is controlled, and according to the second operation list and the first operation list after the deletion operation, the first layer is refreshed to empty the entire content in the first drawing region 812 and retain the content in the second drawing region 822.

In some embodiments, the entire content in the second drawing area 822 may be deleted by selecting the delete control 825 in the second control area 821. For example, when the delete control 825 is selected, a selection interface as shown in fig. 10 is triggered, where the selection interface includes a confirm option and a cancel option, and when the confirm option is selected, the entire contents in the second drawing area 812 are deleted, while the entire contents in the first drawing area 812 are still retained, as shown in fig. 13.

In some embodiments, in response to a selection operation of the delete control 825 in the second control region 821, deleting the operation content stored in the second operation list is controlled, and the first layer is refreshed according to the first operation list and the second operation list after the deletion operation, so as to empty the whole content in the second drawing region 822 and preserve the content in the first drawing region 812.

In some embodiments, each time operation content is input in the first drawing area 812, the controller controls the first operation list to store drawing operation data corresponding to the operation content, and the content input in the first drawing area 812 may be edited to be changed by selecting at least one of the erase control 814, the delete control 814, the cancel control 815, the resume control 81, and the like in the first control area 811, and thus, an operation of editing the content in the first drawing area 812 by selecting at least one of the erase control 814, the delete control 815, the cancel control 818, and the resume control 819, and the like in the first control area 811 may also be regarded as the operation content input in the first drawing area 812. Each time an operation is performed, the controller controls to store the drawing operation data of this time in the drawing operation data set in the first operation list in time order, and since the aforementioned drawing operation data set stores only the operation contents input into the first drawing area 812, the drawing operation data set can be noted as the first drawing operation data set.

In some embodiments, the content input in the second drawing area 822 may be edited by selecting at least one of the erase control 824, the delete control 824, the cancel control 825, and the resume control 826, etc. in the second control area 821, and thus, the operation of editing the content in the second drawing area 822 by selecting at least one of the erase control 824, the delete control 825, the cancel control 818, and the resume control 819, etc. in the second control area 821 may also be regarded as the operation content input in the second drawing area 822. Each time an operation is performed, the controller controls the drawing operation data to be stored in time series in the drawing operation data set of the second operation list. Since the drawing operation data set stores only the operation contents input to the second drawing area 822, the drawing operation data set can be noted as a second drawing operation data set.

It will be appreciated that the first and second painting operation data sets are independent of each other and do not affect each other.

In some embodiments, each time the undo control 818 in the first control area 811 is selected once, the display device reads the first set of drawing operation data, stores the last saved drawing operation data in the first set of drawing operation data into the first recovery data set in the first list of operations, and deletes the drawing operation data in the first set of drawing operation data. Meanwhile, the first layer is refreshed according to the first drawing operation data set and the second drawing operation data set to delete the input content corresponding to the aforementioned drawing operation data in the first drawing area 812.

In some embodiments, each time the recovery control 819 in the first control region 811 is selected, the display device reads the first recovery data set, stores the drawing operation data last saved in the first recovery data set into the first drawing operation data set, and deletes the drawing operation data in the first recovery data set. Meanwhile, the first layer is refreshed according to the first drawing operation data set and the second drawing operation data set to display the input contents corresponding to the aforementioned drawing operation data in the first drawing area 812.

In some embodiments, each time the undo control 828 in the second control field 821 is selected once, the display device reads the second set of drawing operation data, stores the last saved drawing operation data in the second set of drawing operation data into the second restored data, and deletes the drawing operation data in the second set of drawing operation data. Meanwhile, the input contents corresponding to the aforementioned drawing operation data in the second drawing area 822 are deleted.

In some embodiments, each time the resume control 829 in the second control section 821 is selected once, the display device reads the second resume data set, stores the drawing operation data last saved in the second resume data set into the second drawing operation data set, and deletes the drawing operation data in the second resume data set. Meanwhile, the first layer is refreshed according to the first drawing operation data set and the second drawing operation data set to input the input contents corresponding to the aforementioned drawing operation data in the second drawing area 822.

It will be appreciated that since the first recovery data set is stored in the first operation list and the second recovery data set is stored in the second operation list, the first operation list and the second operation list are independent of each other, and thus the first recovery data set and the second recovery data set are independent of each other and do not affect each other.

In some embodiments, referring to fig. 14, when a user selects a toolbar control 817 in the first control area 811, the toolbar 910 corresponding to the toolbar control 817 is triggered and displayed, and the toolbar 910 may include at least one of a save control 911 and a share control 912. When the user selects the toolbar control 827 in the second control area 821, the toolbar 920 corresponding to the toolbar control 827 is triggered and displayed, and the toolbar 920 may include at least one of a save control 921 and a share control 922.

In some embodiments, the user may save the entire content in the first drawing area 812 by selecting the save control 911 in the toolbar 910. For example, when the user selects the save control 911, the controller controls the first operation list to store the target picture in the first drawing area 812 and the first drawing operation data set corresponding to the target picture, so that the display device may display the editable target picture according to the stored first drawing operation data set when the user opens the target picture again later.

In some embodiments, the user may save the entire content in the second drawing area 822 by selecting the save control 921 in the toolbar 920. For example, when the save control 921 is selected, the controller controls the second operation list to store a target picture in the second drawing area 822 and a second drawing operation data set corresponding to the target picture so that when the target picture is opened again later by the user, the display device may display an editable target picture according to the stored second drawing operation data set.

In some embodiments, the sharing control 912 in the toolbar 910 may be selected to share the entire content in the first drawing area 812 to the target receiving device, so that when the target receiving device opens the target picture, the target receiving device may display the editable target picture according to the received first drawing operation data set.

In some embodiments, the sharing control 922 in the toolbar 920 may be selected to share the entire content in the second drawing area 822 to the target receiving device, so that when the target receiving device opens the target picture, the target receiving device may display the editable target picture according to the received second drawing operation data set.

In some embodiments, referring to fig. 15, the first drawing board area 810 further includes an exit control 930, when the user selects the exit control 930 in the first drawing board area 810, the first operation list is controlled to store the target picture and the first drawing operation data set corresponding to the input content in the first drawing area 812, and at the same time, the split screen state of the electronic drawing board interface is cancelled, and the first layer is refreshed according to the second operation list, so that only the content in the second drawing area 822 is presented on the electronic drawing board interface, and the content in the second drawing area 822 is adjusted to a preset size and position. For example, referring to FIG. 16, the content in the second palette region 820 may be enlarged and moved to a center position of the electronic palette interface.

In some embodiments, referring to fig. 17, the second palette region 820 further includes an exit control 940, and when the exit control 940 in the second palette region 820 is selected, the second operation list stores a target picture and a second drawing operation data set corresponding to the content that has been input in the second drawing region 822, and at the same time, the split screen state of the electronic palette interface is canceled, so that only the content in the first drawing region 812 is presented on the electronic palette interface, and the content in the first drawing region 812 is adjusted to a preset size and position. For example, referring to FIG. 18, the content in first palette region 810 may be enlarged and moved to a center position of the electronic palette interface.

In an embodiment of the present application, by locking a display area of an interface corresponding to a certain area, a layer of a locking mode may be added to an area to which a display content belongs, for example, as shown in fig. 21 (a), after a display area of an area B including the area is locked, as shown in fig. 21 (d), the area B includes at least two layers of operation attributes, after the locking of the area B is cancelled, the operation mode of the area B is restored, and an original local locking area still exists in the area to which the display content belongs, that is, a drawing interface corresponding to the area B is restored to a drawing interface shown in fig. 21 (a).

In the practical application process, a user can set one or two of the locking modes in advance according to the practical situation, when the two locking modes are set, the controller outputs confirmation options of the two locking modes before locking the display area of the interface corresponding to a certain area, and the user confirms the specific locking mode.

In order to facilitate understanding, in the drawings corresponding to the embodiments of the present application, if a closed lock exists in a closed line area, the closed line area is indicated to be in a locked mode, if an open lock exists in the closed line area, the closed line area is indicated to be in an unlocked mode, or if a closed/open lock appears at an edge of a drawing interface, the drawing interface is indicated to be in a global locked/unlocked mode.

FIG. 22 is a flow diagram of executing a lock instruction according to some embodiments. As shown in fig. 22, the controller is configured to perform S301 to S303:

S301, responding to a lock instruction for a display area input by a user on a drawing interface of the command inputter.

S302, if the locking instruction is a local locking instruction, responding to the local locking instruction, and determining a local locking curve input by a user in a drawing interface.

It should be noted that, in the actual use process, the local locking curve may be a continuous line, or may be a discontinuous line, or be a plurality of independent lines that are continuously input, where the continuous line may be a line that is input at one time, or may be a continuous line formed by intersecting and combining multiple input lines, and in the local locking curve judgment, a single continuous line is used for judgment. Specifically, the local locking curve can be obtained by directly drawing, inputting coordinate points or selecting, translating, copying and the like of the existing curve on a drawing interface, or directly selecting the existing line graph to perform region selection, amplifying or shrinking the line graph, and finally confirming the input local locking curve.

And S303, determining a local locking area in the drawing interface according to the local locking curve, and locking a display area of the interface corresponding to the local locking area on the drawing interface so that the unlocked display area can be edited.

Fig. 23 is a schematic diagram of a plotted local lock curve according to some embodiments. As shown in fig. 23, the local locking curve may be a curve that independently encloses one or more closed areas, or may be a curve that fails to individually enclose closed areas, where, for an area enclosed by the local locking curve, there is a closed area, each closed area is determined as a local locking area, and a display area of an interface corresponding to the local locking area on the drawing interface is locked.

In the practical application process, when a local locking area exists in the drawing interface, but the area of the local locking area is too large, so that part of display areas which do not need to be locked exist in the local locking area, and the unnecessary display areas need to be removed from the local locking area, in one embodiment of the application, the locking operation of the local locking area can be canceled (controlled by a local unlocking instruction, the local unlocking instruction is described later), and then the second local locking operation is performed again, so that the embodiment of the application needs more operation steps.

In view of the above, the present embodiment provides a third implementation. FIG. 24 is a schematic illustration of a closed region formed by partial lock curves within an existing partial lock region, according to some embodiments. As shown in fig. 24, if there is a closed region in the region enclosed by the local locking curve, and the closed region is located in a certain locking region, the dotted line region with the locking mark is the existing local locking region C, and the local locking curve is drawn in the local locking region C, in this case, after the display region of the interface corresponding to the dotted line region on the drawing interface is locked, the annular region between the local locking curve and the boundary line of the local locking region C may be determined as a local unlocking region, and the display region of the interface corresponding to the local unlocking region on the display is unlocked, so that the original oversized local locking region C is narrowed, and the display region that does not need to be locked is removed, but this manner is only applicable to the edge region of the redetermined local locking region that does not include the original oversized local locking region C, if the edge area of the original oversized local lock area C is included, it is more difficult to draw a local lock curve for redefining the local lock area, and for this case, the embodiment of the present application proposes a fourth implementation manner, by drawing an unclosed local lock curve, that is, an area surrounded by the local lock curve, in which there is an absence of a closed area, and the boundary of the local lock curve and the existing local lock area C forms a closed area, which is located inside the existing local lock area C, and it should be noted that, when the boundary of the local lock curve and the existing local lock area C forms a closed area, which is located inside the existing local lock area C, the inside of the existing local lock area C necessarily includes a plurality of closed areas, for example as shown in fig. 25, the partial lock curve divides an existing partial lock region into two parts (two closed regions), or as shown in fig. 26, divides an existing partial lock region into four parts (a first region, a second region, a third region, and a fourth region), in which case the partial lock region is determined based on the area ratio of a plurality of closed regions inside the existing partial lock region, specifically, the closed region having the smallest area may be determined as a new partial lock region, then the lock pattern of the closed region other than the closed region having the smallest area may be canceled, or the closed region having the largest area may be determined as a new partial lock region, then the lock pattern of the closed region other than the closed region having the largest area may be canceled, or the closed region other than the closed region having the largest area may be determined as a new partial lock region.

In the practical application process, when a local locking area exists in the drawing interface and a display area which is needed to be locked exists in the area adjacent to or connected with the local locking area, besides drawing a completely closed local locking curve and locking the display areas which are needed to be locked, the embodiment of the application also provides a method for adding the display area which is needed to be locked into the existing technical locking area by utilizing the unclosed local locking curve, specifically, as shown in fig. 27, if the boundary between the local locking curve and the existing local locking area forms a closed area and the closed area is outside the existing local locking area, determining the closed area as the local locking area.

In the embodiment of the application, the locking modes comprise a global locking mode and a local locking mode, and the global locking mode can be controlled by a global locking instruction, and after receiving the global locking instruction sent by the command input device, the controller locks the display areas of the interfaces corresponding to all areas on the drawing interface.

When a locking mode exists on the drawing interface, correspondingly, the embodiment of the application also provides a mode for unlocking the region according to the locking mode, wherein the unlocking mode is used for unlocking the locked region so as to be capable of re-editing the display region of the unlocked region.

The command inputter is configured to receive an unlocking command input by a user, wherein the unlocking command comprises a global unlocking command and an unlocking locking command, and the unlocking command can be a single control command (represented by an unlocking button, an unlocking option and the like), can also be a locking operation of a combination of the control command and unlocking region selection (selection, drawing, input or determination of an unlocking region and the like), and is further configured to display a drawing interface with an unlocking mode.

Fig. 28 is a flow diagram of an unlock instruction according to some embodiments. As shown in fig. 28, the controller is configured to perform S901 to S903.

S901, responding to an unlocking instruction for a display area input by a user on a drawing interface of the command inputter.

S902, if the unlocking instruction is a local unlocking instruction, responding to the local unlocking instruction, and determining a local unlocking curve input by a user in a drawing interface.

In the process of judging the local unlocking curve, the local unlocking curve can be obtained by directly drawing a drawing interface, inputting coordinate points or selecting, translating, copying and the like of the existing curve, or directly selecting the existing line graph for region selection, amplifying or shrinking the line graph, and finally confirming the input local unlocking curve.

S903, determining a local unlocking area in the drawing interface according to the local unlocking curve, and unlocking a display area of the interface corresponding to the local unlocking area on the drawing interface, so that the unlocked display area can be edited.

Fig. 29 is a schematic diagram of a partial unlock curve plotted according to some embodiments. As shown in fig. 29, the local unlocking curve may be a curve that independently encloses one or more closed areas, or may be a curve that fails to individually enclose closed areas, where, for an area enclosed by the local unlocking curve, there is a closed area, each closed area is determined to be a local unlocking area, and a display area of an interface corresponding to the local unlocking area on the drawing interface is unlocked.

In the practical application process, when a local unlocking area exists in the drawing interface, but the area of the local unlocking area is too large, so that part of display areas which are not needed to be unlocked exist in the local unlocking area, and when the unnecessary display areas need to be removed from the local unlocking area, in one embodiment of the application, the unlocking operation of the local unlocking area can be canceled, and then the second local unlocking operation is carried out again, so that more operation steps are needed in the embodiment, on the basis of the embodiment, the embodiment provides the second embodiment, and the display areas which are not needed to be unlocked are directly locked through the local locking instruction, but in the practical application process, the problem of difficult drawing of the local locking area possibly exists, and the problem of inconvenient operation also exists.

In view of the above, the present embodiment provides a third implementation. FIG. 30 is a schematic illustration of a closed region formed by a partial unlock curve within an existing partial unlock region, according to some embodiments. As shown in fig. 30, if a closed area exists in the area surrounded by the local unlocking curves, and the closed area is located in a certain unlocking area, the dotted area with the unlocking mark is the existing local unlocking area D, and the local unlocking curve is drawn in the local unlocking area D, in this case, after the display area of the interface corresponding to the dotted area on the unlocking drawing interface, the annular area between the local unlocking curve and the local unlocking area D boundary line may be determined as the local locking area, and the display area of the interface corresponding to the local locking area on the display is locked, so that the display area that does not need to be unlocked is reduced for the original oversized local unlocking area D, but this way is only applicable to the edge area of the local unlocking area that does not include the original oversized local unlocking area D, and if the edge area of the local unlocking area D that does not include the original oversized local unlocking area D is included, it is difficult to draw the local unlocking curve for the redetermined local unlocking area. In view of this situation, the embodiment of the present application proposes a fourth implementation manner, in which a closed area is formed by drawing a local unlocking curve that is not closed, that is, by having an area surrounded by the local unlocking curve, where the boundary between the local unlocking curve and an existing local unlocking area D forms a closed area, and the closed area is located inside the existing local unlocking area D, and it should be noted that, when the boundary between the local unlocking curve and the existing local unlocking area D forms a closed area, and the closed area is located inside the existing local unlocking area D, the inside of the existing local unlocking area D necessarily includes a plurality of closed areas. For example, as shown in fig. 31, the partial unlock curve divides the existing partial unlock region D into two parts (two closed regions), or as shown in fig. 32, the partial unlock curve divides the existing partial unlock region D into four parts (four closed regions), in which case, the partial unlock region is determined based on the area ratio of the plurality of closed regions inside the existing partial unlock region D, specifically, the closed region having the smallest area may be determined as a new partial unlock region, then the unlock pattern of the closed region other than the closed region having the smallest area is canceled, or the closed region having the largest area may be determined as a new partial unlock region, then the unlock pattern of the closed region other than the closed region having the largest area is canceled, or the closed region other than the closed region having the largest area is determined as a new partial unlock region.

In the practical application process, when a local unlocking area exists in the drawing interface, and a display area which is needed to be unlocked is also existing in the area adjacent to or connected with the local unlocking area, besides drawing a complete closed local unlocking curve, the display areas which are needed to be unlocked are unlocked, and the embodiment of the application also provides a method for adding the display area which is needed to be unlocked into the unlocking area in the prior art by using the closed local unlocking curve. As shown in fig. 33, if the local unlocking curve and the boundary of the existing local unlocking region form a closed region, and the closed region is outside the existing local unlocking region, the closed region is determined as a local unlocking region.

In the embodiment of the application, the unlocking modes comprise a global unlocking mode and a local unlocking mode, and the global unlocking mode can be controlled by a global unlocking instruction, and after receiving the global unlocking instruction sent by the command input unit, the controller unlocks the display areas of the interfaces corresponding to all areas on the drawing interface. In order to more conveniently lock or unlock a drawing interface for a user in an actual use process of a display device, a second aspect of the embodiment of the present application further provides another display device, which is aimed at providing a display device that does not need to input a locking instruction or an unlocking instruction, and performs intelligent area locking or area unlocking according to a mode switching curve input by the user and an existing display state of the display device, where the display device includes: a display, a command input, and a controller, the display configured to display a drawing interface with an operation mode, the operation mode including a lock mode and an unlock mode; the command inputter is configured to receive a user input of a mode switching profile, which may be a continuous line, a discontinuous line, or a plurality of independent lines of continuous input.

In one embodiment of the present application, if only the locking mode is present in the mode switching area, the locking mode of the mode switching area is directly switched to the unlocking mode as shown in fig. 35, 36 and 37, and correspondingly, if only the unlocking mode is present in the mode switching area, the unlocking mode of the mode switching area is directly switched to the locking mode as shown in fig. 38, 39 and 40.

As shown in fig. 43, the curve S and the curve L are curves without a closed area, but the curve S and the curve L are in contact with the boundary of the display interface, in the embodiment of the present application, the area formed by the boundary (short side or long side) of the curve S and the curve L and the display area is taken as the closed area formed by the independent enclosure of the curve S and the curve L, that is, the curve S and the curve L are both closed areas, so that the user is ensured not to be affected by the boundary of the display interface in the use process, so as to prevent the situation that when the user draws the instruction curve directly on the display interface of the display, the start point and/or the end point of the instruction curve falls outside the display interface, or a part of the area of the instruction curve exceeds the display interface, resulting in failure of inputting the instruction curve.

In the practical application process, in order to facilitate the operation of the user, the instruction curve input by the user may be intelligently perfected, for example, if the instruction curve does not have a closed area enclosed by the two end points of the instruction curve, the two end points of the instruction curve are connected by straight line segments, the area formed by the connecting line and the instruction curve is used as the closed area enclosed by the instruction curve alone, as shown in fig. 44, the curve M is a curve without the closed area, the two end points of the curve M are connected by two-dot chain lines, and the closed area formed by the curve M and the two-dot chain line is used as the closed area enclosed by the curve M alone.
