[0032] In order to explain the technical solution described in the present invention, the following description will be made by way of specific embodiments. 1 is a schematic flowchart of an implementation method of a display method of a terminal device according to an embodiment of the present invention. As shown in the figure, the method may include the following steps:

[0034] Step S101: Acquire information to be displayed, and store the information to be displayed in a preset storage space.

[0035] In the embodiment of the present invention, the information to be displayed refers to data information saved by the user in advance, and can still be displayed after the terminal device is powered off. When the terminal device is in the down state, the user can operate through the visual interface presented in the terminal device and save some important data information. The important data information can be stored in the form of an image or in the form of text. The storage space is preset in the terminal device, and the user can save the information to be displayed in the preset storage space. The information to be displayed may be stored in the preset storage space by the user, or the information to be displayed designated by the user may be stored in the preset storage space after the terminal device obtains the predetermined instruction.

[0036] Specifically, the acquiring information to be displayed, and storing the information to be displayed in a preset storage space includes

[0037] obtaining the memo information saved by the user, and storing the memo information as the to-be-displayed information in a preset storage space;

[0038] Alternatively, after the second preset condition is detected, a screenshot of the current interface of each application running in the background of the first display screen of the terminal device and/or the terminal device is obtained, and a screen capture image is obtained, and The screen shot image is stored in the preset storage space as the information to be displayed.

In the embodiment of the present invention, the user can save the memo information through the memo preset preset in the terminal device, and store the memo information as the to-be-displayed information in the preset storage space, and the memo information can be edited and saved. Text information can also be image information. For example, in the process of browsing a webpage, the user thinks that there is more important data information in the webpage, and can screen the current webpage and use the screen capture image as the information to be displayed; and edit the text information through the memo, and the terminal device automatically displays the text in the memo. The information screen capture is used as the information to be displayed; of course, the text information in the memo information can be directly saved; of course, the image specified by the user as the memo information can be used as a memo information, and no limitation is imposed here.

[0040] In the process of using the terminal device by the user, the user can edit and save the memo information as the information to be displayed, and the first display of the terminal device by the terminal device after detecting the second preset condition. Screen capture screen, or screen capture of the current interface of each application running in the background of the terminal device, obtaining a screen capture image, and storing the screen capture image as information to be displayed in a preset storage space. Second pre The condition is that the current power of the terminal device is lower than the power threshold. For example, when it is detected that the power of the terminal device is only 4%, which is lower than the power threshold of 5%, the terminal device can automatically take a screenshot of the first display screen, and take a screenshot of the current interface of the application running in the background of the terminal device to obtain a screen capture. The image is stored in the preset storage space as the information to be displayed. In practical applications, different power thresholds can also be set according to different usage conditions.

[0041] In addition, the user may set in advance, which screens of the running interfaces of the applications running in the background of the terminal device after the second preset condition is detected, for example, the user may set in advance to detect the second preset condition. In other words, if the terminal device runs the application A and the application C in the background, the current interface of the application A and the application C is screened. If the second preset condition is detected, the application running in the background of the terminal device is: an application, an application 8, an application C, and an application D, then only the application A and the application C are needed. The current interface screen capture. The current interface refers to the interface that is displayed before the application is switched to the foreground, switched to the front-end operation, or displayed before the application is switched to the background. The screen capture of the current interface of each application running in the background of the terminal device or the screen capture of the current interface of the predetermined application running in the background of the terminal device may be specifically set according to actual conditions, and is not limited herein.

[0042] Step S102: After detecting the first preset condition, shutting down the first display screen of the terminal device, and acquiring the information to be displayed from the preset storage space.

In the embodiment of the present invention, the first preset condition may be a shutdown instruction, that is, when the terminal device receives the instruction to shut down, the first display screen of the terminal device is closed. The terminal device is configured with two display screens: a first display screen and a second display screen, the first display screen and the second display screen can be respectively disposed on two sides of the terminal device, since most of the current terminal devices are relatively thin Therefore, the first display screen and the second display screen can be disposed on two opposite faces of a relatively large area, such as the arrangement shown in FIG. 2. The first display screen may be a liquid crystal display or an LED display screen, and the second display screen may be a display having a low power consumption relative to the first display screen, such as an electronic ink screen. The peer terminal device can also be configured with two central processing units (CPUs), one as the main processor and one as the coprocessor. When the power of the terminal device is sufficient, the main processor of the terminal device works, and the first display screen displays the data information, and the second display screen can set the display state or the closed state. However, when the power is detected to be insufficient, the first display is turned off, and the main processor switches to the protocol. The processor works, the power consumption of the coprocessor is lower than that of the main processor, and the power consumption is less, and the coprocessor obtains the information to be displayed from the preset storage space.

[0044] Step S103: Display the information to be displayed by using a second display screen of the terminal device.

[0045] In the embodiment of the present invention, in a state where the power is insufficient to be turned off, the main processor with high power consumption switches to the coprocessor with low power consumption, and in order to save power, the first display screen is turned off. , the information to be displayed is displayed on the second display with low power consumption. Taking the second display screen as an electronic ink screen as an example, the color in the electronic ink screen is such that charged particles of different colors move in different directions due to different applied electric fields, and different color effects are exhibited on the surface of the electronic ink screen. And only when the color of the displayed screen changes (for example, from black to white), the power is consumed. After the power is turned off, the screen on the electronic ink screen can still be retained. Therefore, the electronic ink screen is very power-saving and can be turned off. The information to be displayed is displayed between the long lines.

[0046] In the embodiment of the present invention, the information to be displayed is obtained, and the information to be displayed is stored in a preset storage space; after the first preset condition is detected, the power consumption of the terminal device is turned off. a display screen, and acquiring the to-be-displayed information from the preset storage space; and displaying the information to be displayed through a second display screen with a lower power consumption of the terminal device. By setting two display screens on the terminal device, when the preset condition is detected, the important information of the user is displayed through the second display with low power consumption, so that the terminal device can still be after the power is insufficiently turned off. Ability to display important data information

3 is a schematic flowchart of a display method of a terminal device according to another embodiment of the present invention. The embodiment is specifically refining how to display the to-be-displayed information by using the embodiment shown in FIG. The second display of the terminal device displays that the method can include the following steps as shown:

[0048] step S301, if the to-be-displayed information is an image to be displayed, acquiring a resolution of the second display screen, and performing scaling processing on the image to be displayed according to a resolution of the second display screen, So that the image to be displayed after the scaling process conforms to the resolution of the second display screen.

[0049] In the embodiment of the present invention, since the resolution of the second display screen may not match the image to be displayed, the second display is acquired before the image to be displayed is displayed on the second display screen. The resolution of the screen, if the image to be displayed matches the resolution of the second display screen, no processing is required, generally the resolution of the first display screen is higher than that of the second display screen, so the image to be displayed generally needs to be zoomed The processing can be matched with the second display screen. Of course, if the information to be displayed is text information, the text content can be directly displayed on the second display screen.

[0050] Step S302: Determine whether the second display screen supports color display.

[0051] In the embodiment of the present invention, taking the electronic ink screen as an example, the color of the electronic ink screen is formed by charged particles of different colors. If the charged particles in the electronic ink screen are only black and white, the color display cannot be supported. If the charged particles of the electronic ink screen are composed of a plurality of charged particles of different colors, color display is supported.

[0052] Step S303: If the second display screen supports color display, display the image to be displayed after the zoom processing through the second display screen.

[0053] Step S304, if the second display screen does not support the color display, the image to be displayed after the scaling process is grayed out and binarized, and the image to be displayed after the binarization process is passed. The second display screen is displayed.

[0054] In the embodiment of the present invention, taking the electronic ink screen as an example, if the electronic ink screen does not support color display, the image to be displayed after the scaling process needs to be grayed out to obtain a gray image, and then Binary processing, first setting a grayscale threshold, setting a pixel point smaller than the grayscale threshold to 0, that is, white, and setting a pixel point greater than or equal to the grayscale threshold to 255, that is, black. In this way, the image to be displayed (black and white image) after the binarization process is obtained, and the black and white image can be displayed on the electronic ink screen. Figure 4 (a) is the image to be displayed, Figure 4 (b) Grayscale and binarized image to be displayed, that is, the display effect of the electronic ink screen

[0055] The embodiment of the present invention enables the image to be displayed to match the second display screen by the processes of scaling processing, grayscale, and binarization processing.

5 is a schematic flowchart of a display method of a terminal device according to another embodiment of the present invention. The embodiment is specifically refining a plurality of to-be-stored in a preset storage space on the basis of the embodiment shown in FIG. Displaying information 吋 how to display the information to be displayed through the second display screen of the terminal device, as shown in the figure, the method may include the following steps:

[0057] Step S501: Determine the number of information to be displayed stored in the preset storage space.

[0058] Step S502: If one information to be displayed is stored in the preset storage space, the information to be displayed is displayed on the second display screen of the terminal device. [0059] Step S503: If at least two to-be-displayed information are stored in the preset storage space, one of the to-be-displayed information is displayed on the second display screen of the terminal device according to a preset display rule.

[0060] In the embodiment of the present invention, there may be more than one information to be displayed stored in the preset storage space. If there is only one information to be displayed, the information to be displayed is displayed through the second display screen of the terminal device. If two or more files are stored, it is necessary to display a message to be displayed first, and which one is displayed, and the display rule can be preset. For example, the storage time can be displayed according to the storage time of each information to be displayed, for example, the storage will be performed. The earliest one to be displayed information display may also be set to display the screen capture information obtained by the first display screen capture by detecting the second preset condition first.

[0061] Step S504: After obtaining the instruction for switching, displaying the next to-be-displayed information of the currently displayed information through the second display screen of the terminal device.

[0062] In the embodiment of the present invention, if the preset storage space stores at least two information to be displayed, after displaying a to-be-displayed information, if the user wants to continue to view other information to be displayed, the terminal device may preset The button sends a command to switch to the terminal device. After the terminal device issues an instruction to switch, the next to-be-displayed information of the currently displayed information can be displayed through the second display screen of the terminal device. The next to-be-displayed information refers to the next to-be-displayed information according to the information currently displayed in the preset display rule. For example, if the display is sorted according to the storage time of each information to be displayed, the next information to be displayed of the currently displayed information can be obtained according to the storage time division. If it is set to display the second preset condition 吋 the screen capture information obtained by the first screen capture screen is displayed, after the switch instruction is acquired, the storage time of the screen capture information is the latest among the information to be displayed. The information to be displayed can be returned to the earliest information to be displayed in the storage area for display.

[0063] The embodiment of the present invention specifically refines the existence of a plurality of information to be displayed in the preset storage space, and how to display the plurality of to-be-displayed information one by one.

It should be understood that the size of the serial number of each step in the foregoing embodiment does not mean the order of execution sequence, and the execution order of each process should be determined by its function and internal logic, and should not constitute the implementation process of the embodiment of the present invention.
