Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Because the terminal with the large display screen is inconvenient to carry, the terminal can be made of flexible materials, so that the terminal can be folded, and the terminal with the large display screen is convenient to carry.

Referring to fig. 1 and fig. 2, a block diagram of a terminal 100 according to an embodiment of the present invention 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.

Processor 110 may include one or more processing cores. The processor 110 connects various parts within the overall terminal 100 using various interfaces and lines, and performs various functions of the terminal 100 and processes data by executing or executing instructions, programs, code sets, or instruction sets stored in the memory 120 and calling data stored in the memory 120. Alternatively, the processor 110 may be implemented in hardware using at least one of Digital Signal Processing (DSP), Field-Programmable Gate Array (FPGA), and Programmable Logic Array (PLA). The processor 110 may integrate one or more of a Central Processing Unit (CPU), a Graphics Processing Unit (GPU), a modem, and the like. Wherein, the CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for rendering and drawing the content to be displayed by the touch display screen 130; the modem is used to handle wireless communications. It is understood that the modem may not be integrated into the processor 110, but may be implemented by a single chip.

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. Such as a local notification service, a remote push service, an advertising framework, a game tool framework, a messaging User Interface (UI) framework, a User Interface UIKit framework, a map framework, and so forth.

In the framework shown in FIG. 2, the framework associated with most applications includes, but is not limited to: a base framework in the core services layer 340 and a UIKit framework in the touchable layer 380. The base framework provides many basic object classes and data types, provides the most basic system services for all applications, and is UI independent. While the class provided by the UIKit framework is a basic library of UI classes for creating touch-based user interfaces, iOS applications can provide UIs based on the UIKit framework, so it provides an infrastructure for applications for building user interfaces, drawing, processing and user interaction events, responding to gestures, and the like.

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 taking the terminal 100 as an example that includes two parts of a housing and a connecting assembly for connecting the housing (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 (i.e., a front facing 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 an image display method according to an embodiment of the present invention, for a terminal having a foldable display screen and a front camera, as shown in fig. 7, the image display method may include:

step 701, detecting whether the display screen is in a preset state, wherein the preset state is a state between an unfolding state and a folding state. If the display screen is in the preset state, executing step 702; if the display screen is not in the preset state, step 701 is executed.

Alternatively, the image display method may be applied to a terminal having a foldable display screen and a front camera. Referring to fig. 3, 4 and 5, the terminal may include a first housing 131, a second housing 132 and a connecting assembly 133 connected between the first housing 131 and the second housing 132, wherein the first housing 131 and the second housing 132 are folded by the connecting assembly 133. Fig. 8 is a schematic view of an expanded state of a display screen according to an embodiment of the present invention, and fig. 8 is a schematic view of a terminal in which the display screen is in the expanded state. As shown in fig. 8, the first housing 131 may include a first supporting surface Y1 connected to the rear surface of the display screen X, and the second housing 132 includes a second supporting surface Y2 connected to the rear surface of the display screen X. A front camera Z and a display screen X in the terminal are both arranged on the display side of the terminal.

The terminal may detect a folding angle formed by the first support plane Y1 and the second support plane Y2 at the display side in step 701. For example, with continuing reference to fig. 8, when the display screen X of the terminal is in the unfolded state, the folding angle formed by the first supporting plane Y1 and the second supporting plane Y2 on the display side is 180 degrees. As shown in fig. 9, when the display screen X is folded inward, the folding angle formed by the first supporting surface Y1 and the second supporting surface Y2 on the display side ranges from 180 degrees to 0 degrees (e.g., 90 degrees). As shown in fig. 10, when the display screen X is folded outward, the folding angle formed by the first supporting surface Y1 and the second supporting surface Y2 on the display side ranges from 180 degrees to 360 degrees.

The terminal can be prestored with a preset angle range, and when the detected folding angle is within the preset angle range, the terminal can determine that the display screen in the terminal is in a preset state at the moment. Wherein, 0 degree, 180 degrees and 360 degrees are all located outside the preset angle range. For example, when the display screen of the terminal can be folded inward (e.g., the terminal is an inward-folding screen terminal, or the terminal is a terminal capable of being folded by 360 degrees), the preset angle range may be: [ 90-180 degrees ]. When the display screen at terminal can be outwards folded (if the terminal is outer folding screen terminal, or the terminal is terminal that can 360 degrees foldings), this preset angle scope can be: (180-270 degrees), or the preset angle range can be [ 90-180 degrees ] and [ 90-180 degrees ]. That is, the preset state is a state in which the display screen of the terminal is between the unfolded state and the folded state, or a state between the folded state and the unfolded state.

And step 702, controlling the front camera to acquire an image. Step 703 is performed.

When the terminal detects that the display screen is in the preset state, it can be determined that the user needs to look into a mirror on the display screen of the terminal at the moment, and at the moment, the terminal can control the front camera to collect images of the user (such as face images of the user).

And step 703, controlling the display screen to display the image.

The terminal can control the display screen to display the image collected by the front camera after controlling the front camera to collect the image, so that a user can see the image on the display screen, and the mirror-looking effect on the display screen of the terminal is realized.

Optionally, a front-facing camera in the terminal may be disposed on a first housing of the terminal, and when the terminal controls the display screen to display an image collected by the front-facing camera, the terminal may control an area on the first housing in the display screen to display the image. For example, as shown in fig. 9 or 10, when the display screen of the terminal is folded inward, the second housing 132 may be placed on the placement surface, the first housing 131 may face the user, and the front camera Z may be disposed on the first housing 131. At this time, if the terminal wants to control the display screen to display the image collected by the front camera Z, the terminal may control the area a on the first housing 131 in the display screen to display the image.

In the image display method provided by the embodiment of the invention, when a user needs to look a mirror on a display screen in a terminal and the display screen of the terminal is in a folded state, the user can turn the display screen of the terminal into a preset state, for example, the display screen is turned off so that an included angle formed by a first supporting surface and a second supporting surface of the terminal on a display side of the terminal is within a preset angle range, so as to trigger the terminal to control a front camera and the display screen to realize the mirror function.

Fig. 11 is a flowchart of another image display method provided in an embodiment of the present invention, for a terminal having a foldable display screen and a front camera, as shown in fig. 11, the image display method may include:

step 1101, detecting whether the display screen is in a preset state, wherein the preset state is a state between an unfolding state and a folding state. If the display screen is in the preset state, executing step 1102; if the display screen is not in the preset state, step 1101 is executed.

It should be noted that step 1101 may refer to step 701, and details of the embodiment of the present invention are not described herein.

Step 1102, detecting a holding time length of the display screen in a preset state.

When the terminal detects that the display screen is in the preset state, the terminal needs to further detect the holding duration of the display screen in the preset state for further determining that the user needs to look into a mirror on the display screen of the terminal at the moment.

And 1103, controlling the front camera to acquire an image when the holding time is longer than the preset time.

If the terminal detects that the display screen is in a preset state and the detected holding time is longer than the preset time, the terminal can accurately determine that the user needs to look into a mirror on the display screen of the terminal at the moment, and at the moment, the terminal can control the front camera to collect images of the user (such as face images of the user). For example, the preset time period may be 1 second.

And step 1104, controlling the display screen to display the image.

It should be noted that step 1104 may refer to step 703, and details of the embodiment of the present invention are not described herein.

In the image display method provided by the embodiment of the invention, when a user needs to look a mirror on a display screen in a terminal and the display screen of the terminal is in a folded state, the user can break the display screen of the terminal into a preset state and control the holding time of the display screen in the preset state to be longer than the preset time so as to trigger the terminal to control the front camera and the display screen to realize the mirror function.

In summary, in the terminal control method provided in the embodiment of the present invention, when the terminal detects that the display screen is in the preset state and the holding time of the preset state is longer than the preset time, the front-facing camera is controlled to collect an image and the display screen is controlled to display the image, so as to implement the mirror viewing function of the terminal. That is, when a user needs to look into a mirror on a display screen in the terminal, the display screen can be directly broken into a preset state, the holding time longer than the preset time is kept, and a camera button on the display screen does not need to be clicked after the display screen is broken, so that the operation steps of the terminal are simplified.

Fig. 12 is a flowchart of a method of another image display method according to an embodiment of the present invention, for a terminal having a foldable display screen and a front camera, as shown in fig. 12, the image display method may include:

step 1201, detecting whether the display screen is in a preset state, wherein the preset state is a state between an unfolding state and a folding state. If the display screen is in the preset state, step 1202 is executed; if the display screen is not in the preset state, step 1201 is executed.

It should be noted that step 701 may be referred to in step 1201, and details of the embodiment of the present invention are not described herein.

And 1202, detecting the holding time of the display screen in the preset state.

It should be noted that step 1202 may refer to step 1102, and details of the embodiment of the present invention are not described herein.

Step 1203, detecting light intensity of the surrounding environment of the terminal when the keeping time length is longer than the preset time length.

Because the prerequisite that the user looked at the mirror on the display screen at terminal is that the light intensity of the surrounding environment at terminal is stronger, consequently, when detecting that the display screen is in the preset state, and keep for a long time and be greater than when presetting for a long time, need look at the mirror on the display screen at terminal this moment for further definite user, the terminal still need further detect the light intensity of the surrounding environment at terminal this moment.

And 1204, controlling the front camera to collect the image when the light intensity of the surrounding environment is greater than the preset light intensity.
