[0014] Reference will now be made in detail to exemplary embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Whenever possible, the same reference numerals are used in the drawings and the description to refer to the same or like parts.

[0015] Figure 1 is a functional block diagram of a display device according to an embodiment of the present invention. Figure 1 The display device 10 may include various electronic devices with display functions, such as a smart phone, a tablet computer, a notebook computer, an e-reader, or a game console.

[0016] The display device 10 may include a rollable display 11, a storage circuit 12, an input / output (IO) device 13, and a processor 14. The rollable display 11 is used to display images and is a flexible display. For example, the rollable display 11 may include a flexible display such as an electronic paper (E-ink) or an organic light emitting diode (OLED) display. It should be noted that the display type of the rollable display 11 is not limited thereto.

[0017] The storage circuit 12 is used to store data. For example, the storage circuit 12 may include a volatile storage circuit and a non-volatile storage circuit. The volatile storage circuit is used to store data volatilely. For example, the volatile storage circuit may include a random access memory (RAM) or a similar volatile storage medium. The non-volatile storage circuit is used to store data non-volatilely. For example, the non-volatile storage circuit may include a read-only memory (ROM), a solid state disk (SSD), a traditional hard disk drive (HDD) or a similar non-volatile storage medium. It should be noted that the type of the storage circuit 12 is not limited thereto.

[0018] The input / output device 13 is used to receive input signals or send output signals. For example, the input / output device 13 may include a physical keyboard, a touch panel, a mouse, a network interface card and / or a speaker. It should be noted that the type of the input / output device 13 is not limited thereto.

[0019] The processor 14 is connected to the rollable display 11, the storage circuit 12, and the input / output device 13. The processor 14 can be used to be responsible for the overall or partial operation of the display device 10. For example, the processor 14 can be a central processing unit (CPU), a graphics processing unit (GPU), or other programmable general-purpose or special-purpose microprocessors, digital signal processors (DSP), programmable controllers, application specific integrated circuits (ASIC), programmable logic devices (PLD), or other similar devices or combinations of these devices.

[0020] In one embodiment, the processor 14 may present at least one virtual screen and a toolbar image in the display interface of the rollable display 11. A virtual screen may cover a portion of the display area in the display interface of the rollable display 11. For example, the resolution of each virtual screen may be expressed as N pixels × M pixels. It should be noted that if multiple virtual screens are simultaneously presented in the display interface of the rollable display 11, these virtual screens do not overlap with each other. In addition, the processor 14 may control the image screen presented by each virtual screen.

[0021] In one embodiment, each virtual screen may be used to present a target image. For example, the target image may include one of a desktop image and an application image. The desktop image may include a default desktop image provided by the operating system running on the processor 14 or a desktop image set by the user. The application image may include an execution screen of at least one application currently running in the foreground.

[0022] In one embodiment, the processor 14 may present at least one virtual button in the toolbar image. Each virtual button is used to start an application. In one embodiment, the processor 14 may also present more useful information in the toolbar image (such as the battery information or network connection information of the display device 10), which is not limited by the present invention.

[0023] In one embodiment, the processor 14 may detect the physical state of the rollable display 11. In response to the change in the physical state of the rollable display 11, the processor 14 may adjust the presentation positions of the toolbar image and the at least one virtual screen in the display interface of the rollable display 11.

[0024] In one embodiment, the physical state of the rollable display 11 changes may include the physical state of the rollable display 11 changing from a certain physical state (also referred to as a first physical state) to another physical state (also referred to as a second physical state). In one embodiment, in response to the physical state of the rollable display 11 changing from the first physical state to the second physical state, the processor 14 may adjust the presentation position of the toolbar image in the display interface of the rollable display 11 from a certain position (also referred to as a first position) to another position (also referred to as a second position). The first position is different from the second position.

[0025] In one embodiment, the change in the physical state of the rollable display 11 may include a change in the size of the display interface of the rollable display 11. For example, in the first physical state, the display interface of the rollable display 11 may have a certain size (also referred to as the first size). In addition, in the second physical state, the display interface of the rollable display 11 may have another size (also referred to as the second size). The first size is different from the second size.

[0026] In one embodiment, the size of the display interface of the rollable display 11 may be used to describe the length or width of the display interface of the rollable display 11. For example, in one embodiment, in the first physical state, the length of the display interface of the rollable display 11 may be a first size, and in the second physical state, the length of the display interface of the rollable display 11 may be a second size. Alternatively, in one embodiment, in the first physical state, the width of the display interface of the rollable display 11 may be a first size, and in the second physical state, the width of the display interface of the rollable display 11 may be a second size.

[0027] In one embodiment, the distance between the first position and the second position may be positively correlated to the difference between the first size and the second size. Thus, in one embodiment, after the physical state of the rollable display 11 changes, the greater the difference between the first size and the second size, the greater the distance the toolbar image is moved in the display interface of the rollable display 11.

[0028] In one embodiment, it is assumed that the toolbar image is presented in a certain virtual screen (also referred to as the first virtual screen). In response to a change in the physical state of the rollable display 11, such as a change from the first physical state to the second physical state, the processor 14 may adjust the presentation position of the first virtual screen in the display interface of the rollable display 11 from a certain position (also referred to as the third position) to another position (also referred to as the fourth position). The third position is different from the fourth position. At the same time, without changing the relative position between the first virtual screen and the toolbar image, the processor 14 may adjust the presentation position of the toolbar image in the display interface from the first position to the second position.

[0029] In other words, in one embodiment, assuming that the tool bar image is presented in the first virtual screen, in response to a change in the physical state of the rollable display 11, such as a change from the first physical state to the second physical state, the processor 14 may synchronously move the tool bar image and the first virtual screen in the display interface of the rollable display 11. In particular, during the process of moving the tool bar image and the first virtual screen, the relative position between the first virtual screen and the tool bar image is not changed.

[0030] In one embodiment, in response to a change in the physical state of the rollable display 11, the processor 14 may adjust the total number of virtual screens presented on the display interface of the rollable display 11. For example, at a certain point in time, the total number of virtual screens presented on the display interface of the rollable display 11 may be positively correlated to the size of the display interface of the rollable display 11 at that point in time. That is, if at a certain point in time, the size of the display interface of the rollable display 11 is larger, then at that point in time, the number of virtual screens presented on the display interface of the rollable display 11 may be greater.

[0031] Figure 2 is a schematic diagram showing the physical state change of a rollable display according to an embodiment of the present invention. Figure 2 , assuming that the display device 10 includes a display device 20, and the rollable display 11 includes a rollable display 21. The rollable display 21 may present an image through a display interface 22. In one embodiment, the display device 20 may further include a physical keyboard 23. For example, the physical keyboard 23 may belong to Figure 1 Alternatively, in one embodiment, the electronic device 20 may not have a physical keyboard 23.

[0032] In one embodiment, the processor 14 may detect whether the size of the display interface 22 of the rollable display 11 changes. In response to the size of the display interface 22 changing, such as being unfolded or retracted, the processor 14 may determine that the physical state of the rollable display 11 changes.

[0033] In one embodiment, in response to the display interface 22 being extended, the size (e.g., length) of the display interface 22 may be changed from D(1) to D(2), and D(2) is greater than D(1). That is, by extending the display interface 22, the display area of ​​the display interface 22 may be gradually enlarged. However, in response to the display interface 22 being retracted, the size (e.g., length) of the display interface 22 may be changed from D(2) to D(1). That is, by retracting the display interface 22, the display area of ​​the display interface 22 may be gradually reduced.

[0034] It should be noted that Figure 2 In the embodiment, the display interface 22 of the rollable display 11 is unfolded or retracted along the length direction of the display interface 22 as an example of the change in the physical state of the rollable display 11. However, in another embodiment, the change in the physical state of the rollable display 11 may also include, for example, the display interface 22 of the rollable display 11 is unfolded or retracted along the width direction of the display interface 22, and the present invention is not limited thereto.

[0035] Figure 3Ais a schematic diagram showing the presentation position of the adjustment toolbar image and the virtual screen in the display interface of the rollable display according to an embodiment of the present invention. Figure 3A In one embodiment, it is assumed that the display interface of the rollable display 11 includes a display interface 30 .

[0036] In one embodiment, in a preset state, a virtual screen 31 (i.e., a first virtual screen) and a toolbar image 310 may be presented in the display interface 30. The toolbar image 310 may be presented in the virtual screen 31. For example, the toolbar image 310 may be presented at the bottom of the virtual screen 31. For example, virtual buttons 311 to 314 may be presented in the toolbar image 310. The virtual buttons 311 to 314 are used to start corresponding applications, respectively. It should be noted that the presentation position of the toolbar image 310 in the virtual screen 30 and the total number, type, and order of the virtual buttons presented in the toolbar image 310 may be adjusted according to practical needs, and the present invention is not limited thereto.

[0037] In one embodiment, in response to a change in the physical state of the rollable display 11, such as the display interface 30 being unfolded, the processor 14 may synchronously move the virtual screen 31 and the toolbar image 310. For example, as the display interface 30 is unfolded, the processor 14 may synchronously move the virtual screen 31 and the toolbar image 310 upward in the display interface 30. For example, in the process of moving the virtual screen 31 and the toolbar image 310, the presentation position of the toolbar image 310 in the display interface 30 may be changed from the original position (i.e., the first position) to a new position (i.e., the second position), and at the same time, the presentation position of the virtual screen 31 in the display interface 30 may be changed from the original position (i.e., the third position) to a new position (i.e., the fourth position), as shown in FIG. Figure 3A In particular, during the process of moving the virtual screen 31 and the tool bar image 310 , the relative position between the virtual screen 31 and the tool bar image 310 can remain unchanged.

[0038] In one embodiment, in response to a change in the physical state of the rollable display 11, such as the display interface 30 being unfolded, the processor 14 may also present at least a portion of the virtual screen 32 in the display interface 30. It should be noted that the virtual screens 31 and 32 do not overlap each other. For example, after the virtual screen 31 and the toolbar image 310 are synchronously moved up, at least a portion of the virtual screen 32 may be presented below the virtual screen 31. As the display interface 30 is unfolded to a greater extent (i.e., the size of the display interface 30 is larger), more portions of the virtual screen 32 may be presented in the display interface 30. In addition, before the display interface 30 is unfolded, the virtual screen 32 may not be presented in the display interface 30.

[0039] Figure 3Bis a schematic diagram showing a plurality of toolbar images and a plurality of virtual screens in a display interface of a rollable display according to an embodiment of the present invention. Figure 3B , continued by Figure 3A In one embodiment, after further expanding the display interface 30, the processor 14 may simultaneously present the virtual screens 31-33 and the toolbar images 310-330 in the display interface 30. For example, the toolbar images 310-330 may be located at the bottom of the virtual screens 31-33, respectively. Virtual buttons 311-314 may be presented in the toolbar image 310. Virtual buttons 321-324 may be presented in the toolbar image 320. Virtual buttons 331-334 may be presented in the toolbar image 330. It should be noted that the presentation position of each toolbar image in the virtual screen and the total number, type and order of virtual buttons presented in each toolbar image may be adjusted according to practical needs, and the present invention is not limited thereto.

[0040] In one embodiment, after the display interface 30 is expanded, the total number of toolbar images presented in the display interface 30 may be less than or equal to the total number of virtual screens presented in the display interface 30. Figure 3B In another embodiment, after the display interface 30 is expanded, only at least one or at least two of the toolbar images 310 - 330 may be presented.

[0041] In one embodiment, in response to the physical state of the rollable display 11 changing again, such as the display interface 30 being retracted, the processor 14 may further gradually hide at least a portion of the virtual screen 33 (and 32). Figure 3A and Figure 3B For example, when gradually retracting the previously expanded display interface 30, at least a portion of the virtual screen 33 may be hidden first. As the display interface 30 is continuously retracted, at least a portion of the virtual screen 32 may be continuously hidden until the display interface 30 returns to the default state.

[0042] Figure 3C is a schematic diagram showing the presentation position of the adjustment toolbar image and the virtual screen in the display interface of the rollable display according to an embodiment of the present invention. Figure 3C In one embodiment, after the display interface 30 is unfolded, the processor 14 may continue to present the toolbar image 340 at a specific position in the display interface 30. For example, the specific position may be the bottom of the display interface 30. Virtual buttons 341-344 may be presented in the toolbar image 340. In other words, in one embodiment, no matter how the physical state of the rollable display 11 (or the size of the display interface 30) changes, the toolbar image 340 may continue to be presented at the bottom of the display interface 30.

[0043] Figure 3D is a schematic diagram showing the presentation position of the adjustment toolbar image and the virtual screen in the display interface of the rollable display according to an embodiment of the present invention. Figure 3D In one embodiment, after the display interface 30 is unfolded, the processor 14 may continue to present the toolbar image 350 at a specific position in the display interface 30. For example, the distance between this specific position and the bottom of the display interface 30 is h, and the value of h may be set according to practical needs and / or may be adjusted by the user. Virtual buttons 351 to 354 may be presented in the toolbar image 350. In other words, in one embodiment, no matter how the physical state of the rollable display 11 (or the size of the display interface 30) changes, the distance (i.e., h) between the presented toolbar image 350 and the bottom of the display interface 30 may be maintained unchanged.

[0044] It should be noted that in Figure 3C and Figure 3D In the embodiment of , the processor 14 may also present one or more virtual screens in the display interface 30 according to the physical state of the rollable display 11 (or the size of the display interface 30), and the total number and / or position change of the presented virtual screens may not affect the presentation position of the toolbar images 340 and / or 350. Figure 3C In the embodiment of FIG. 3 , even if multiple virtual screens are presented in the expanded display interface 30 , the total number of the toolbar images 340 can still be maintained at one, and the toolbar image 340 can continue to be presented at the bottom of the display interface 302 . Figure 3D In the embodiment of FIG. 5 , even if multiple virtual screens are presented in the expanded display interface 30 , the total number of the toolbar images 350 can be maintained at one, and the distance between the toolbar image 350 and the bottom of the display interface 30 can be maintained at h.

[0045] In one embodiment, in response to a change in the physical state of the rollable display 11, the processor 14 may adjust the resolution of the virtual screen presented on the display interface of the rollable display 11. By adjusting the resolution of the virtual screen, the image presented by the virtual project may have a better picture presentation effect, thereby improving the user experience.

[0046] by Figure 3A For example, in one embodiment, in response to the display interface 30 being expanded, the processor 14 may expand the coverage of the virtual screen 31 in the display interface 30 by adjusting the resolution of the virtual screen 31. Thus, as the display interface 30 is gradually expanded, the coverage of the virtual screen 31 in the display interface 30 may also gradually increase, thereby improving the user experience of the user operating or viewing the virtual screen 31. In addition, in response to the display interface 30 being retracted, the processor 14 may reduce the coverage of the virtual screen 31 in the display interface 30 by adjusting the resolution of the virtual screen 31.

[0047] In one embodiment, in response to the physical state of the rollable display 11 changing, the processor 14 may continue to present the specific object in the display interface of the rollable display 11. This can avoid the situation where the user cannot find the specific object after adjusting the size of the display interface.

[0048] by Figure 3A For example, in one embodiment, assuming that after the display interface 30 is unfolded, according to the user operation, the processor 14 may set a specific object presented in the virtual screen 32 as an object that needs to be continuously displayed. For example, this specific object may include a specific window and / or a specific operable object presented in the virtual screen 32. Thereafter, during or after the display interface 30 is retracted, regardless of whether the virtual screen 32 is still presented in the display interface 30, the processor 14 may control the rollable display 11 to continuously present this specific object (i.e., the object that is set to be continuously displayed) in the display interface 30 (i.e., according to the virtual screen 32 that is reduced or hidden, the corresponding object that needs to be continuously displayed is changed to be displayed in the virtual screen 31), thereby avoiding the situation where the user cannot find the specific object after the display interface 30 is retracted.

[0049] Figure 4 is a flow chart of an image presentation method according to an embodiment of the present invention. Figure 4 In step S401, at least one virtual screen and a toolbar image are presented in a display interface of the rollable display. In step S402, the physical state of the rollable display is detected. In step S403, in response to a change in the physical state of the rollable display, the presentation position of the toolbar image and the virtual screen in the display interface is adjusted.

[0050] However, Figure 4 The steps in the above are described in detail, so I will not repeat them here. It is worth noting that Figure 4 Each step in the above process can be implemented as multiple program codes or circuits, and the present invention is not limited thereto. Figure 4 The method can be used in conjunction with the above exemplary embodiments or can be used alone, and the present invention is not limited thereto.

[0051] In summary, compared to the traditional method where toolbar images can only be presented at a specific position in the display interface of the display (e.g., the bottom of the display interface), the image presentation method and display device proposed in the embodiments of the present invention can dynamically adjust the presentation position of the toolbar image and the virtual screen in the display interface of the rollable display according to the current physical state of the rollable display. In addition, the total number of virtual screens presented by the display interface of the rollable display, the resolution of the virtual screen, and the presentation position of specific objects in the display interface can all be dynamically adjusted according to the current physical state of the rollable display. As a result, the user's operating experience for the rollable display can be effectively improved.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
