Referring to fig. 1 and 2, a block diagram of a terminal 100 according to an exemplary embodiment of the present application is shown. The terminal 100 may be a smart phone, a tablet computer, an e-book, and the like. The terminal 100 in the present application may include one or more of the following components: a processor 110, a memory 120, and a touch display screen 130.
The Memory 120 may include a Random Access Memory (RAM) or a Read-Only Memory (Read-Only Memory). Optionally, the memory 120 includes a non-transitory computer-readable medium. The memory 120 may be used to store instructions, programs, code sets, or instruction sets. The memory 120 may include a stored program area and a stored data area, wherein the stored program area may store instructions for implementing an operating system, instructions for at least one function (such as a touch function, a sound playing function, an image playing function, etc.), instructions for implementing various method embodiments described below, and the like; the storage data area may store data (such as audio data, a phonebook) created according to the use of the terminal 100, and the like.
Taking an operating system as an Android (Android) system as an example, programs and data stored in the memory 120 are shown in fig. 1, and a Linux kernel layer 220, a system runtime layer 240, an application framework layer 260, and an application layer 280 are stored in the memory 120. The Linux kernel layer 220 provides underlying drivers for various hardware of the terminal 100, such as a display driver, an audio driver, a camera driver, a bluetooth driver, a Wi-Fi driver, power management, and the like. The system runtime library layer 240 provides the main feature support for the Android system through some C/C + + libraries. For example, the SQLite library provides support for a database, the OpenGL/ES library provides support for 3D drawing, the Webkit library provides support for a browser kernel, and the like. Also provided in the system Runtime layer 240 is an Android Runtime library (Android Runtime), which mainly provides some core libraries that can allow developers to write Android applications using the Java language. The application framework layer 260 provides various APIs that may be used in building applications, and developers may build their own applications by using these APIs, such as activity management, window management, view management, notification management, content provider, package management, session management, resource management, and location management. At least one application program runs in the application layer 280, and the application programs may be a contact program, a short message program, a clock program, a camera application, etc. of the operating system; or an application program developed by a third-party developer, such as an instant messaging program, a photo beautification program, and the like.
Taking an operating system as an IOS system as an example, programs and data stored in the memory 120 are shown in fig. 2, and the IOS system includes: a Core operating system Layer 320(Core OS Layer), a Core Services Layer 340(Core Services Layer), a Media Layer 360(Media Layer), and a touchable Layer 380(Cocoa Touch Layer). The kernel operating system layer 320 includes an operating system kernel, drivers, and underlying program frameworks that provide functionality closer to hardware for use by program frameworks located in the kernel services layer 340. The core services layer 340 provides system services and/or program frameworks, such as a Foundation framework, an account framework, an advertisement framework, a data storage framework, a network connection framework, a geographic location framework, a motion framework, and so forth, that are needed by the application. The media layer 360 provides audiovisual interfaces for applications, such as graphics-related interfaces, audio-related interfaces, video-related interfaces, and audio/video transmission technology wireless broadcast (AirPlay) interfaces. The touchable layer 380 provides various common interface-related frameworks for application development, and the touchable layer 380 is responsible for user touch interaction operations on the terminal 100.

The touch display screen 130 is used for receiving a touch operation of a user on or near the touch display screen using any suitable object such as a finger, a touch pen, or the like, and displaying a user interface of each application program. The touch display 130 is generally provided at a front panel of the terminal 100.
As shown in fig. 3, the terminal 100 includes a first housing 41, a second housing 42, and a connecting assembly 43 connected between the first housing 41 and the second housing 42, and the first housing 41 and the second housing 42 are folded upside down by the connecting assembly 43.
The first housing 41 includes a first supporting surface connected to the back surface of the touch display screen and a first back surface opposite to the first supporting surface, and the second housing 42 includes a second supporting surface connected to the back surface of the touch display screen and a second back surface opposite to the second supporting surface. Accordingly, the touch display screen includes a first display area 131, a second display area 132 and a third display area 133, wherein the first display area 131 corresponds to the position of the first housing 41, the second display area 132 corresponds to the position of the second housing 42, and the third display area 133 corresponds to the position of the connecting assembly 43. In one implementation, the first display region 131, the second display region 132 and the third display region 133 are made of flexible materials and have a certain expansion and contraction ductility; in another implementation, only the third display region 133 is made of a flexible material, and the first and second display regions 131 and 132 are made of a non-flexible material.
In an alternative implementation, the connection assembly 43 of the terminal 100 is of a manual construction. When the user manually separates the first casing 41 and the second casing 42, the terminal 100 is changed from the folded state to the unfolded state; when the user manually closes the first housing 41 and the second housing 42, the terminal 100 changes from the unfolded state to the folded state.
In an alternative implementation, the connection assembly 43 of the terminal 100 is of an electric construction, for example, the connection assembly 43 is provided with an electric rotating member such as an electric motor. Under the driving of the electric rotating component, the first housing 41 and the second housing 42 automatically close or separate, so that the terminal 100 has two states of unfolding and folding.
The terminal 100 may be divided into an outer folder terminal and an inner folder terminal according to whether the touch display screen is exposed in a folded state. Wherein:
external folding screen terminal
The outer folding screen terminal is a terminal which has a folding angle of 180 degrees and is completely exposed out of the touch display screen in a folding state. As shown in fig. 3, the terminal 100 is an outer folder screen terminal. In the unfolded state, the first supporting surface of the first casing 41 of the terminal 100 is flush with the second supporting surface of the second casing 42 (i.e. the included angle is 180 °), and the first display area 131, the second display area 132 and the third display area 133 of the touch display screen are located on the same plane; in the process of the terminal 100 changing from the unfolded state to the folded state, as shown in fig. 3, the first back surface of the first housing 41 and the second back surface of the second housing 42 are close to each other, and the included angle between the first supporting surface and the second supporting surface is changed from 180 ° to 0 °; in the folded state, as shown in fig. 4, the first supporting surface of the first casing 41 of the terminal 100 is parallel to the second supporting surface of the second casing 42 (the included angle between the first casing 41 and the second casing 42 is 0 °), so that the touch display screen is in a U-shaped folded state, in which the third display area 133 of the touch display screen forms an exposed U-shaped arc surface.
In an alternative implementation, in the folded state, all or part of the display area of the touch display screen is used for displaying the user interface. For example, as shown in fig. 4, in the folded state, only the second display region 132 is used to display the user interface, or only the third display region 133 is used to display the user interface.
Terminal with internal folding screen
The inner-folding-screen terminal refers to a terminal that can be folded at an angle of 180 ° and in a folded state, the touch display screen is (entirely or partially) converged. As shown in fig. 5, the terminal 100 is an inner folder screen terminal. In the unfolded state, the first supporting surface of the first casing 41 of the terminal 100 is flush with the second supporting surface of the second casing 42 (i.e. the included angle is 180 °), so that the touch display screen is in a planar unfolded state (the first display area 131, the second display area 132 and the third display area 133 are located on the same plane); in the process of the terminal 100 changing from the unfolded state to the folded state, as shown in fig. 5, the first supporting surface of the first housing 41 and the second supporting surface of the second housing 42 are close to each other, that is, the included angle between the first supporting surface and the second supporting surface is changed from 180 ° to 0 °; in the folded state, the first supporting surface of the first housing 41 of the terminal 100 is parallel to the second supporting surface of the second housing 42, so that the touch display screen is in a U-shaped folded state in which the third display area 133 of the touch display screen forms a U-shaped arc surface that is inwardly converged. In an alternative implementation, in the folded state, no user interface is displayed in all display areas of the touch display screen.
In addition to providing a touch display screen on the support surface of the housing, a touch display screen may also be provided on the first back surface of the first housing 41 and/or the second back surface of the second housing 42. When the inner folding screen terminal is in a folding state, the touch display screen arranged on the back face of the shell is used for displaying a user interface, and the user interface is the same as or different from the user interface displayed by the touch display screen in an unfolding state.
In other possible implementations, the foldable angle of the terminal 100 may also be 360 ° (both inward and outward), and in the folded state, the touch display screen is exposed or converged on the terminal, which is not limited in this embodiment.
In the terminal 100 shown in fig. 3 to 5, the first housing 41 and the second housing 42 have the same or similar size, and the folding manner of the terminal 100 is called symmetrical folding. In other possible implementations, the terminal 100 may also be folded asymmetrically. When the asymmetric folding is adopted, the sizes of the first casing 41 and the second casing 42 may be different or different by more than a threshold (for example, 50% or 60% or 70%), and accordingly, the area of the first display region 131 in the touch display screen is different from the area of the second display region 132 by more than a threshold.
Illustratively, as shown in fig. 6, the terminal 100 is an asymmetrically folded outer folded screen terminal, and the first housing 41 has a size larger than that of the second housing 42. In the folded state, the area of the first display region 131 is larger than that of the second display region 132.
In fig. 3 to 6, only by taking an example that the terminal 100 includes two parts of a housing and a connecting assembly for connecting the housing as an example (the terminal is in a two-fold structure), in other possible implementations, the terminal 100 may include n parts of the housing and n-1 connecting assemblies, and accordingly, the touch display screen of the terminal 100 includes 2n-1 display areas, and the n-1 display areas corresponding to the connecting assemblies are made of a flexible material, so as to implement the terminal in the n-fold structure, which is not limited in this embodiment.
At least one other component is also provided in the terminal 100, the at least one other component including: cameras, fingerprint sensors, proximity light sensors, distance sensors, etc. In some embodiments, at least one other component is disposed on the front, side, or back of the terminal 100, such as a fingerprint sensor disposed on the back or side of the housing, a camera disposed above the touch display screen 130.
In other embodiments, at least one other component may be integrated within or below the touch screen display 130. In some embodiments, a bone conduction earpiece is provided inside the terminal 100; other components on the front panel of the conventional terminal are integrated in the whole area or a partial area of the touch display screen 130, for example, after a photosensitive element in the camera is split into a plurality of photosensitive pixels, each photosensitive pixel is integrated in a black area in each display pixel in the touch display screen 130, so that the touch display screen 130 has an image capturing function. The terminal 100 has a higher screen occupation ratio due to the integration of at least one other component within or under the touch display screen 130.
In some optional embodiments, an edge touch sensor is disposed on a single side, or two sides (e.g., two left and right sides), or four sides (e.g., four upper, lower, left and right sides) of the middle frame of the terminal 100, and is configured to detect at least one of a touch operation, a click operation, a press operation, a slide operation, and the like of a user on the middle frame. The edge touch sensor may be any one of a touch sensor, a thermal sensor, a pressure sensor, and the like. The user may apply operations on the edge touch sensor to control the application in the terminal 100.
In addition, those skilled in the art will appreciate that the configuration of terminal 100 as illustrated in the above-described figures is not intended to be limiting of terminal 100, and that terminals may include more or less components than those illustrated, or some components may be combined, or a different arrangement of components. For example, the terminal 100 further includes a radio frequency circuit, an input unit, a sensor, an audio circuit, a Wireless Fidelity (WiFi) module, a power supply, a bluetooth module, and other components, which are not described herein again.
Fig. 7 is a flowchart of a display screen unfolding method according to an exemplary embodiment of the present application, for example, the display screen unfolding method is applied to the terminal 100 with a foldable display screen shown in fig. 1, a middle frame of the terminal 100 is further provided with a pressure sensor, and the display screen unfolding method includes:

Optionally, a pressure sensor is disposed on the middle frame of the terminal, and the pressure sensor is configured to receive a touch pressure at an area where the pressure sensor is disposed, and the touch pressure generated by a user on the middle frame of the terminal can be detected by the pressure sensor.
And 703, controlling the folding display screen to be unfolded from the folding state to the unfolding state according to the touch pressure.
Optionally, an electric rotating member is disposed in the terminal, and the electric rotating member is disposed between two screen regions of the foldable display screen, and by the electric rotating member, automatic folding or unfolding of the two screen regions of the foldable display screen can be achieved.
Optionally, the foldable display screen can be controlled to be unfolded from the folded state to the bent unfolded state or controlled to be unfolded from the folded state to the plane unfolded state according to different pressure values of the touch pressure; optionally, the terminal may further control the opening and closing degree of the foldable display screen when the foldable display screen is unfolded from the folded state to the unfolded state according to the difference of the detected duration of the touch pressure. Illustratively, when receiving the touch pressure, the terminal starts to control the foldable display screen to unfold from the folded state, and when detecting that the touch pressure is over, the terminal ends to control the foldable display screen to unfold from the folded state to the unfolded state, and at this time, the foldable display screen may be in the plane unfolded state or the bending unfolded state.
In summary, the terminal can be automatically switched from the folded state to the unfolded state by applying a pressure signal to the middle frame of the terminal by the user, so that the user does not need to apply an external force from the joint of the two screen areas. Even if the laminating of two screen regions is comparatively inseparable, the user also only needs the one hand to exert pressure signal on the center and just can easily open folding display screen to solved because two screen regions laminating of folding display screen are too inseparable, the unable one hand of user control should fold the problem that display screen expanded for the expansion state from fold condition.

The first threshold may be set by the user, or may be preset by the developer. Illustratively, the first threshold is 3N (Newton), and when the pressure value of the touch pressure is greater than 3N, that is, the pressure applied by the user on the middle frame of the terminal is greater than 3N, the terminal controls the foldable display screen to be unfolded from the folded state to the unfolded state.

1 |

2 |
| 5N- |
