The screen expansion instruction can be correspondingly a shortening instruction or an extending instruction, and the shortening instruction is used for controlling the flexible screen to be shortened, namely controlling the distance between the first shaft or the terminal screen frame and the second shaft to be shortened; the elongation instruction is used for controlling the elongation of the flexible screen, namely controlling the distance between the first axis or the terminal screen frame and the second axis to be far. The screen expansion instruction can be automatically adjusted by the terminal according to display information, wherein the display information comprises at least one of the following: how much/how much content is displayed, the application name is displayed, and the mode in which it is located. For example, if the display content is more than the preset size, automatically generating an elongation instruction, and if the display content is less than the preset size, automatically generating a contraction instruction; if in the panoramic photographing mode or the electronic book reading mode, an automatic extension instruction is generated, the distance between the first shaft and the second shaft is controlled to be far, and a larger range of view finding is realized; if the music/motion application is opened or the music or motion mode is played, if the display content is less, a shortening instruction is automatically generated, namely the distance between the first shaft and the second shaft is controlled to be close, and the small screen display is realized, so that the electric quantity is saved and the portable device is convenient to carry; optionally, before executing the automatic generation instruction, displaying screen adjustment prompt information, and after obtaining user confirmation, performing screen size adjustment; the user can preset the screen expansion instruction when different applications are opened or the screen expansion instruction in different mobile phone modes, so that when the preset applications or the preset modes are opened, the corresponding screen size is adapted, and the same multi-screen display effect is achieved.

In an embodiment, the screen expansion instruction corresponds to at least one display mode of full screen, equal front screen length and rear screen length, and greater front screen length than rear screen length.

According to the contraction instruction and the display mode corresponding to the contraction instruction or the screen target length, the driving assembly is controlled to work, a part of the flexible screen can be converted into a rear screen from the front side through the first shaft and/or the second shaft, and the flexible screen enters a display mode that the front screen is equal to the rear screen in length or the front screen is longer than the rear screen in length; according to the extension instruction and the display mode or the screen target length corresponding to the extension instruction, the driving assembly is controlled to work, the rear screen can be turned to the front side through the first shaft and/or the second shaft, and the display mode that the full screen or the front screen length is larger than the rear screen length is entered. When the lengths of the front screen and the rear screen are equal, the terminal is minimum in size and convenient to carry; when the display mode is in a full screen display mode, more information can be contained at one time, and a large screen effect is realized; when the front screen length is longer than the rear screen length, the terminal size and the front screen size are moderate, and the general use requirements are met. Thus, the user can adjust the length of the screen according to the unused use requirement, and a satisfactory effect is obtained.

Optionally, if the current display mode is full screen, full screen display or split screen display can be performed on the display content, that is, all information is displayed on the front screen, or the user can perform split screen display setting on the content according to the needs, one part of the screen normally displays mobile phone content, and the other part of the screen displays user-defined display content, so that the intuitiveness and the operation convenience of information acquisition are improved. If the current display mode is that the lengths of the front screen and the rear screen are equal, the current display content is displayed on the front screen and the rear screen in a divided mode, namely, the front screen and the rear screen can display information simultaneously, and the display mode can be displayed in a divided mode according to the display content, so that a user can define at least one of the display content, the display position, the display color, the display effect and the switching mode of the front screen and the rear screen: for example, the user may define different information display areas, such as different APP icons displayed on different display screens or application/function content displayed directly, such as one document displayed on the front screen, another document displayed on the back screen for ease of comparison, or text of an article displayed on the front screen and a catalog of articles displayed on the back screen; or the weather module is displayed on the upper side of the rear screen, and the future call and the prompt are embodied on the lower side of the rear screen in the form of a card; optionally, the user can define the display format and the color of two screens, the front screen is color, and the rear screen is black and white, so as to achieve the purpose of saving electricity; optionally, the user can realize the rapid switching of the display contents of the front and rear screens by clicking the front and rear screen switching instruction, so that the mobile phone is prevented from being turned over to realize the acquisition of multiple contents. If the current display mode is that the front screen length is greater than the rear screen length, displaying prompt information and/or notification information on the rear screen, wherein the front screen is an interface with a conventional size and the rear screen is slightly smaller under the condition that the front screen is larger than the rear screen in front and smaller in rear, so that the rear screen can be used for displaying the prompt information and/or the notification information, such as notification, incoming calls, time, weather, photographing parameters or photographing preview pictures, and the like, thereby increasing the display space of the front screen; or the user can define at least one of the display content, the display position, the display color, the display effect and the display mode of the rear screen: for example, the user can define the display modes of different information, such as notification prompts, and the incoming call reminding information screen can display the information; weather information and movement information are displayed under a bright screen; photographing parameters, wherein photographing previews are displayed in a self-photographing mode; the user can set the weather module to be displayed on the upper side of the rear screen, and the future and prompt is embodied on the lower side of the rear screen in the form of a card; the user can define the display format and color of two screens, the front screen is color, and the rear screen is black and white, so as to achieve the purpose of saving electricity.

Optionally, when the flexible screen is in the contracted state, the screen on the corresponding side can be lightened according to the facing direction of the user, and/or the screen on the non-corresponding side (such as the opposite side) can be extinguished, so that power consumption can be saved while seamless switching is performed. In actual implementation, the direction of the user facing can be defined by the camera, the side with the face, or the direction of the user facing can be defined by the upward side detected by the gravity sensor, or the number of operating points of the screen can be detected, and the direction of the user facing can be defined by the side with more operating points.
