The main screen on the front side of the mobile terminal may be a liquid crystal display (lcd) or an Organic Light-Emitting Diode (OLED) display, and the sub-screen on the back side of the mobile terminal may be an electronic ink screen. Illustratively, the mobile terminal may be a handset.
The inventor finds that the display characteristics of the electronic ink screen are: the electronic ink screen is dependent on reflected light rays instead of emitted light rays, and the electronic ink screen can reflect light rays like common paper, so that display contents can be naturally displayed under any lighting conditions (non-reflection, and display can be performed under strong light). Therefore, the payment code or the ticket checking code to be scanned is pushed to the electronic ink screen by the liquid crystal screen of the mobile terminal and then is displayed on the current page of the electronic ink screen, or the electronic ink screen is displayed as a screen locking image when the electronic ink screen is in a screen locking state, so that the electronic ink screen realizes a display function depending on the reflected light of the surrounding environment, the power consumption of the mobile terminal is reduced, and the mobile terminal does not need to be unlocked repeatedly to light the screen.
Fig. 1 is a flowchart of an image display method for a mobile terminal according to an embodiment of the present invention, where the mobile terminal includes a main screen and a secondary screen that are oppositely disposed, and the secondary screen is an electronic ink screen. As shown in fig. 1, the method may include:

And 102, if the auxiliary screen is in the screen locking state, displaying the target image on a screen locking page of the auxiliary screen.
When the mobile terminal detects the secondary screen display instruction, whether the secondary screen is in the screen locking state can be further detected, and when the secondary screen is in the screen locking state, the mobile terminal can directly display the target image on the screen locking page of the secondary screen, namely the target image can be set as the screen locking image of the secondary screen.
And 103, if the auxiliary screen is not in the screen locking state, displaying a target image on the current page of the auxiliary screen, and setting the target image as the screen locking image of the auxiliary screen.
If the mobile terminal detects that the secondary screen is not in the screen locking state, the target image can be directly displayed on the current page of the secondary screen, and the target image is determined as the screen locking image of the secondary screen, so that the secondary screen can display the target image in the unlocking state and the screen locking state for a long time.
In summary, the embodiment of the present invention provides an image display method for a mobile terminal, where the mobile terminal can obtain a target image according to a received secondary screen display instruction, and directly display the target image on a screen locking page of a secondary screen when the secondary screen is in a screen locking state; when the secondary screen is not in the screen locking state, the target image is displayed on the current page of the secondary screen and is set as the screen locking image of the secondary screen, and the secondary screen is an electronic ink screen which can reflect light rays like common paper, so that the displayed target image can be displayed more naturally under any illumination condition, and the power consumption of the mobile terminal is effectively reduced; and the target image is used as a screen locking image to be displayed, a user does not need to repeatedly light the screen, and the user operation is simple.
Fig. 2-1 is a flowchart of another image display method for a mobile terminal according to an embodiment of the present invention, where the mobile terminal includes a main screen and a secondary screen that are oppositely disposed, and the secondary screen is an electronic ink screen. As shown in fig. 2-1, the method includes:
In a first optional implementation manner of the embodiment of the present invention, as shown in fig. 2-2, the step of generating, by the mobile terminal, the sub-screen display instruction according to the received preset sub-screen display operation may include:
In the embodiment of the invention, when a user wants to capture the screen of the content displayed on the home screen of the mobile terminal, the screen capture operation can be executed on the home screen. The screen capture operation may be an operation of clicking a screen capture icon, or may also be an operation of double-clicking or long-pressing a display screen, and the like, which is not limited in the embodiment of the present invention. After receiving the screen capture operation through the main screen, the mobile terminal can capture the image displayed on the main screen.
When the mobile terminal receives the screen capturing operation through the main screen, prompt information can be displayed on the main screen, and the prompt information can be used for prompting a user whether to display the captured image on the auxiliary screen.
For example, assuming that the user clicks a screen capture icon on the main screen of the mobile terminal, as shown in fig. 2 to 3, the mobile terminal may display prompt information 011 on the main screen 01 according to the received screen capture operation, where the prompt information 011 may include prompt words "whether to display the captured image on the sub-screen", and a "ok" icon and a "return" icon.
And 2013, receiving the auxiliary screen display operation responding to the prompt message through the main screen.
When the user determines to display the intercepted image on the sub-screen at the prompt of the prompt information, a sub-screen display operation in response to the prompt information may be performed. For example, the user may click on the "ok" icon in the prompt information 011 on the main screen 01, and the mobile terminal may receive the sub-screen display operation through the main screen 01.
In a second optional implementation manner of the embodiment of the present invention, a staple entry icon may be displayed on a main screen of the mobile terminal, and the sub-screen display operation may be an operation (for example, a click operation or a long-press operation) performed on the staple entry icon.
For example, fig. 2-4 are schematic diagrams of a pin entry icon according to an embodiment of the present invention, and as shown in fig. 2-4, a menu bar 012 may be displayed below the main screen 01 of the mobile terminal, the pin entry icon 0121 may be displayed in the menu bar 012, and a return icon and a home page icon, etc. may also be displayed in the menu bar 012.
It should be noted that the sub-screen display operation may also be an operation of pressing a blank of the main screen for a long time, or the sub-screen display operation may also be an operation of pressing a designated physical key (for example, pressing a power key and a volume key at the same time).
And step 2014, generating a sub-screen display instruction according to the sub-screen display operation.
Further, the mobile terminal may generate an auxiliary screen display instruction according to the received auxiliary screen display operation, where the auxiliary screen display instruction may be used to instruct to acquire the target image displayed on the main screen.
It should be noted that, in the embodiment of the present invention, when the mobile terminal detects a screen capture operation for the main screen, it may be detected whether the captured image includes a two-dimensional code or a barcode to be scanned, and when the mobile terminal detects that the captured image includes the two-dimensional code or the barcode to be scanned, the sub-screen display instruction may be automatically generated, so that the mobile terminal may display the target image on the sub-screen according to the sub-screen display instruction, thereby effectively improving flexibility in displaying the target image.
Or, when the mobile terminal detects that the main screen is in a no-operation state and is switched from the awakening state to the screen-off state, the auxiliary screen display instruction can be generated, so that the mobile terminal can display the target image on the auxiliary screen according to the auxiliary screen display instruction, and at the moment, the user can directly check the target image through the auxiliary screen without awakening the main screen again, thereby effectively simplifying the user operation.
In the embodiment of the present invention, the target image may include an image such as a two-dimensional code or a barcode that needs to be displayed for a long time, and may also include a character string (for example, an address or a telephone number) that needs to be displayed for a long time.
The step of acquiring the target image displayed on the main screen may include:
in an optional implementation manner of the embodiment of the present invention, the memory in the mobile terminal may include a main screen memory for storing a main screen display image, a sub-screen memory for storing a sub-screen display image, and a shared memory, and an image stored in the shared memory may be displayed on both the main screen and the sub-screen. After the mobile terminal intercepts the image displayed on the main screen according to the screen capturing operation, the screen capturing image can be stored in the shared memory. And then the mobile terminal can directly read the screen capture image from the shared memory and display the screen capture image according to the auxiliary screen display instruction.
In another optional implementation manner of the embodiment of the present invention, the mobile terminal may monitor the secondary screen display instruction in real time through a preset monitoring function, and when the secondary screen display instruction is monitored, may directly obtain a binary code corresponding to the target image, and push the binary code to the secondary screen for display. Or, when monitoring the secondary screen display instruction, the mobile terminal may further obtain the bitmap file of the target image, store the bitmap file in a shared memory (e.g., a stack memory of codes) or a system memory, then read the bitmap file of the target image from the shared memory or the system memory, and display the bitmap file on the secondary screen.
Specifically, in step 201, if the sub-screen display instruction is generated by triggering a screen capture operation, the mobile terminal may directly obtain the pre-captured image displayed on the main screen according to the sub-screen display instruction.
For example, after the mobile terminal receives an operation of clicking the "ok" icon shown in fig. 2-3, an image displayed on the home screen 01 captured in advance by the mobile terminal is obtained.
In step 201, if the sub-screen display instruction is not generated by the trigger of the screen capture operation, the mobile terminal may directly capture the target image displayed on the main screen when acquiring the target image.
For example, after the mobile terminal receives an operation of clicking on the drawing pin entry icon 0121 shown in fig. 2 to 4, the target image displayed on the main screen 01 may be directly intercepted.
It should be noted that, in the embodiment of the present invention, the mobile terminal may acquire the target image displayed on the secondary screen in addition to the target image displayed on the primary screen. Specifically, when the mobile terminal receives a preset sub-screen display operation through the sub-screen, or when the mobile terminal detects a screen capture operation for the sub-screen and the captured image includes a two-dimensional code or a barcode to be scanned, a sub-screen display instruction for instructing to acquire a target image displayed on the sub-screen may be generated. After detecting the sub-screen display instruction, the mobile terminal can determine the target image as the screen locking image of the sub-screen, so that the target image can be continuously displayed after the sub-screen is locked.
And step 203, detecting whether the auxiliary screen is in a screen locking state.
In the embodiment of the invention, when the mobile terminal detects the secondary screen display instruction, the secondary screen may be in a screen locking state or an unlocking state, and at the moment, the mobile terminal can detect whether the secondary screen is in the screen locking state or not, and then display the target image on the secondary screen in different modes according to the detected screen state of the secondary screen. Specifically, when the mobile terminal detects that the secondary screen is in the screen locking state, step 204 may be executed; when it is detected that the secondary screen is not in the screen-locked state, step 205 may be performed.
And step 204, displaying the target image on the lock screen page of the auxiliary screen.
The mobile terminal detects that the secondary screen is in the screen locking state, the target image can be directly displayed on a screen locking page of the secondary screen, namely the target image is determined as the screen locking image of the secondary screen, so that the target image can be displayed for a long time when the secondary screen is in the screen locking state again after the secondary screen is unlocked.
For example, as shown in fig. 2 to 5, when the mobile terminal detects that the secondary screen 02 is in the screen-locked state, the target image containing the two-dimensional code may be directly displayed on the screen-locked page of the secondary screen, so that the user may perform ticket verification through the target image containing the two-dimensional code.
It should be noted that, while the mobile terminal displays the target image on the lock screen page of the secondary screen, a new page may be added to the secondary screen, and the display image of the new page is determined as the target image. In the embodiment of the invention, the secondary screen of the mobile terminal can comprise a plurality of pages, and the user can switch the secondary screen to display different pages by performing sliding operation on the secondary screen.
Further, in the embodiment of the present invention, the mobile terminal may further use the added new page as a home page of the multiple pages, where the home page may be a page displayed after the auxiliary screen of the mobile terminal is turned on and unlocked.
And step 205, displaying the target image on the current page of the secondary screen, and setting the target image as a screen locking image of the secondary screen.
When the mobile terminal detects the secondary screen display instruction, if the mobile terminal detects that the secondary screen is not in the screen locking state, as an optional implementation manner, the mobile terminal can refresh the display image of the current page of the secondary screen to be the target image, and simultaneously determine the target image to be the screen locking image of the secondary screen, so that the target image can still be displayed for a long time when the secondary screen is in the screen locking state.
As another optional implementation manner, the mobile terminal may further add a new page in the secondary screen, display the target image in the new page, and determine the target image as the screen locking image of the secondary screen. And the mobile terminal can also display the added new page as a home page of the auxiliary screen.
For example, it is assumed that the secondary screen includes three pages, the secondary screen is not currently in the screen locking state, the displayed page is a preset primary page, and an electronic book is displayed on the primary page. The mobile terminal may add a fourth page in the sub-screen, display the target image in the fourth page, and determine the target image as the lock screen image of the sub-screen. When the time length of the secondary screen in the no-operation state exceeds the preset time length, the secondary screen can enter the screen locking state, and the target image can be displayed on the screen locking page of the secondary screen at the moment, so that the long-time display of the target image is realized. The preset duration may be pre-configured by the mobile terminal or may be set by the user.
It should be noted that, for a scene in which a display image of a current page of the secondary screen is refreshed as a target image, in order to enable a user to know a position of the page where the target image is located, and to facilitate the user to process the target image, when the mobile terminal unlocks the secondary screen for the first time or returns to the secondary screen table for the first time after the display image of the current page is refreshed as the target image, the page where the target image is located may be directly displayed on the secondary screen, and when the secondary screen is unlocked each time after the mobile terminal is moved, the secondary screen may display the page displayed before the last screen locking, or when the secondary screen first page is returned each time after the mobile terminal is moved, the secondary screen may display a preset first page of a plurality of pages. The user can perform sliding or clicking operation and the like to enable the secondary screen of the mobile terminal to display the page where the target image is located.
For a scene of adding a new page in the auxiliary screen, in order to enable a user to know the position of the new page and facilitate the user to process a target image displayed by the new page, when the mobile terminal unlocks the auxiliary screen for the first time after the new page is added or returns to the table top of the auxiliary screen for the first time, the new page can be directly displayed on the auxiliary screen, and when the auxiliary screen is unlocked each time after the mobile terminal is started, the auxiliary screen can display a page displayed before last screen locking, or when the auxiliary screen returns to the first page of the auxiliary screen each time after the mobile terminal is started, the auxiliary screen can display a preset first page of a plurality of pages. The user may cause the sub-screen of the mobile terminal to display the new page by performing a sliding operation.
Further, in order to enable the user to more intuitively know the position of the new page in the multiple pages of the first page of the mobile terminal, the page number prompt icon of the new page may be different from the page number prompt icons of other pages. The page number prompting icon is generally displayed below the display screen and can be used for indicating the number of pages included in the display screen and the position of the current page.
For example, assuming that a new page is added to the sub-screen 02 of the mobile terminal and the new page is the first page of the four pages of the sub-screen, as shown in fig. 2 to 6, the shape of the page number prompting icon 021 of the new page may be a pentagon, and the shape of the page number prompting icon 022 of the other pages may be a circle, which are different in shape.
And step 206, when a preset deleting operation aiming at the target image is received, deleting the target image and restoring the screen locking image of the auxiliary screen into the preset image.
When the user does not need the mobile terminal to continuously display the target image, in order to not affect the normal use of the mobile terminal, the user can execute the preset deleting operation aiming at the target image on the secondary screen, and the mobile terminal can delete the target image after receiving the preset deleting operation through the secondary screen.
Specifically, if the mobile terminal adds a new page in the secondary screen of the mobile terminal when displaying the target image, and displays the target image on the new page, the mobile terminal can directly delete the new page when deleting the target image; if the mobile terminal does not add a new page when displaying the target image, but directly refreshes the display image of the current page of the secondary screen to be the target image, when deleting the target image, the mobile terminal can refresh the page displayed with the target image in the secondary screen again so as to enable the display image of the page to be the image before displaying the target image.
In an optional implementation manner of the embodiment of the present invention, a deletion icon may also be displayed on a page in the secondary screen on which the target image is displayed, and the preset deletion operation may be an operation (for example, a click operation or a long-press operation, etc.) performed on the deletion icon. Of course, the preset deleting operation may also be an operation of pressing a blank of the secondary screen for a long time, an operation of pressing a designated physical key (for example, pressing a power key and a volume key at the same time), and the like, which is not limited in the embodiment of the present invention.
For example, as shown in fig. 2 to 6, a delete icon 023 may be further displayed on the page on which the target image is displayed in the sub-screen, and when the user wishes to delete the target image, the delete icon 023 may be clicked, and the mobile terminal may receive an operation of clicking the delete icon 023 through the sub-screen 02, so as to delete the target image.
Further, after the target image is deleted, the mobile terminal can restore the screen locking image of the auxiliary screen to the preset image. Specifically, if the lock screen image of the secondary screen of the mobile terminal is the pre-configured designated image before the target image is displayed, after the target image is deleted, the mobile terminal may restore the lock screen image of the secondary screen to the pre-configured designated image. If the mobile terminal does not pre-configure the lock screen image of the secondary screen as a certain specified image before displaying the target image, that is, the lock screen image of the secondary screen is the image displayed before locking the screen, after deleting the target image, when the secondary screen of the mobile terminal is in the lock screen state, the lock screen interface of the secondary screen can continue to display the image displayed before locking the screen.
In the embodiment of the present invention, the mobile terminal may further store the target image in a private folder preset in the shared memory, where the private folder may store a plurality of target images, and the plurality of target images may be stored according to the order of the acquisition time. When the mobile terminal deletes a certain target image according to the received preset deletion operation, the mobile terminal can also keep the original data of the target image in the private folder, so that the target image can be recovered when needed.
In addition, when the mobile terminal is restarted, if a preset deletion operation for the target image is not received before the mobile terminal is powered off, the mobile terminal may display the recently stored target image on the secondary screen after the restart.
In summary, the embodiment of the present invention provides an image display method for a mobile terminal, where the mobile terminal can obtain a target image according to a received secondary screen display instruction, and directly display the target image on a screen locking page of a secondary screen when the secondary screen is in a screen locking state; when the secondary screen is not in the screen locking state, the target image is displayed on the current page of the secondary screen and is set as the screen locking image of the secondary screen, and the secondary screen is an electronic ink screen which can reflect light rays like common paper, so that the displayed target image can be displayed more naturally under any illumination condition, and the power consumption of the mobile terminal is effectively reduced; and the target image is used as a screen locking image to be displayed, a user does not need to repeatedly light the screen, and the user operation is simple.
