Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides electronic equipment and a display control method. The display control method can be applied to electronic equipment, that is, an execution main body of the display control method can be the electronic equipment provided by the embodiment of the application. Referring to fig. 1, fig. 1 is a schematic view of a first structure of an electronic device 10 according to an embodiment of the present disclosure. An electronic device, such as electronic device 10 of fig. 1, may be a computing device, such as a laptop computer, a computer monitor containing an embedded computer, a tablet computer, a cellular telephone, a media player, or other handheld or portable electronic device, a smaller device (such as a wristwatch device, a hanging device, an earphone or headphone device, a device embedded in eyeglasses, or other device worn on the head of a user, or other wearable or miniature device), a television, a computer display that does not contain an embedded computer, a gaming device, a navigation device, an embedded system (such as a system in which an electronic device with a display is installed in a kiosk or an automobile), a device that implements the functionality of two or more of these devices, or other electronic devices. In the exemplary configuration of fig. 1, the electronic device 10 is a portable device, such as a cellular telephone, media player, tablet computer, or other portable computing device. Other configurations may be used for the electronic device 10, if desired. The illustration in fig. 1 is merely exemplary.

As shown in fig. 1, the electronic device 10 includes a first body 100, a second body 200, a flexible display 300, and a processor 400. One end of the flexible display screen 300 is connected to the first body 100, and the other end of the flexible display screen 300 is connected to the second body 200. For example, the flexible display 300 may be directly and fixedly connected to the first body 100 or the second body 200, and the flexible display 300 may also be, but is not limited to, fixedly connected to the first body 100 or the second body 200 through a connecting member (such as a driving belt or a driving rack). The processor 400 may be disposed in the first body 100 or may also be disposed in the second body 200. For example, a main board may be provided in the first body 100, and the processor 400 may be provided on the main board. The Processor 400 may be, for example, an Application Processor (AP). The processor 400 may be used to perform various functions of the electronic device 10 and process data to thereby monitor the electronic device 10 as a whole.

It is understood that the first body 100 and the second body 200 may provide a supporting function for the electronic devices in the electronic apparatus 10 to mount the electronic devices in the electronic apparatus 10 together. For example, the first body 100 and the second body 200 may support the flexible display screen 300. For another example, electronic devices such as a camera, a receiver, a circuit board, and a power supply in the electronic device 10 may be mounted on the first body 100 and/or the second body 200 for fixing.

The first body 100 and the second body 200 may have a hollow frame structure, or may have a thin plate-like or sheet-like structure. For example, the first body 100 and the second body 200 may include a structure like a drawer or comb teeth. It is understood that the first body 100 and the second body 200 may be provided with, but not limited to, a sliding or drawing structure such as a sliding rail, a sliding way, etc. to enable the second body 200 to move relative to the first body 100. Accordingly, the user may slide, pull, etc. the first body 100 and the second body 200 to realize the relative movement of the first body 100 and the second body 200.

Wherein the first body 100 and the second body 200 can be relatively moved in a direction approaching or departing from each other. When the second body 200 moves relative to the first body 100, the flexible display screen 300 can be driven to expand or contract, or the flexible display screen 300 can be driven to expand or contract, so that the expanded length of the flexible display screen 300 changes accordingly. The unfolded length of the flexible display 300 is the same as or in a conversion relation with the moving distance of the second body 200 relative to the first body 100. For example, if the movement distance of the second body 200 relative to the first body 100 is L, the extended length of the flexible display 300 may be L or have a conversion relation with L. Accordingly, the extended length of the flexible display screen 300 can be accurately detected by detecting the movement distance of the second body 200 with respect to the first body 100. Furthermore, the electronic device 10 can control the display state of the flexible display 300 according to the extended length of the flexible display 300, for example, adjust the display interface layout of the flexible display 300, and adjust the content displayed by the flexible display 300.

It is understood that the flexible display 300 may be switched between the first and second configurations when the second body 200 moves relative to the first body 100. Wherein the second morphology is different from the first morphology. The first configuration may be one of an expanded state, an intermediate state, and a collapsed state, and the second configuration may be another one of the expanded state, the intermediate state, and the collapsed state. Thus, the flexible display 300 can be switched between any two states of the unfolded state, the intermediate state and the folded state.

Fig. 1 is a schematic view of the flexible display 300 in a folded state. Wherein the furled state may be a state finally formed by the relative movement of the first body 100 and the second body 200 in a direction approaching each other. For example, the electronic device 10 may include a first side and a second side opposite to each other, wherein the first side may be a front side of the electronic device 10, and the second side may be a back side of the electronic device 10. When the flexible display screen 300 is in the collapsed state, a portion of the flexible display screen 300 may be located on a first side of the electronic device 10 and a portion of the flexible display screen 300 may be located on a second side of the electronic device 10. It is understood that the portion of the flexible display 300 on the first side of the electronic device 10 may be exposed and form a display surface of the electronic device 10 for displaying images, text, and the like. The portion of the flexible display 300 on the second side of the electronic device 10 may be hidden inside the electronic device 10 and not visible to the user during use.

Referring to fig. 2, fig. 2 is a schematic view of a second structure of the electronic device 10 according to the embodiment of the present disclosure. Fig. 2 is a schematic diagram of the flexible display 300 in an intermediate state. The intermediate state may be a state in which the first body 100 and the second body 200 are relatively moved in a direction away from each other such that the flexible display 300 is partially located at a first side of the electronic device 10 and partially located at a second side of the electronic device 10. Likewise, the portion of the flexible display 300 on the first side of the electronic device 10 may form a display surface, and the portion on the second side of the electronic device 10 may be hidden inside the electronic device 10. It will be appreciated that in the neutral state, relative to the collapsed state, the portion of the flexible display 300 on the first side of the electronic device 10 is increased, and the portion on the second side of the electronic device 10 is decreased, thereby increasing the display area of the electronic device 10.

Referring to fig. 3, fig. 3 is a schematic structural diagram of a third electronic device 10 according to an embodiment of the present disclosure. Fig. 3 is a schematic diagram of the flexible display 300 in an unfolded state. The unfolded state refers to a state in which the first body 100 and the second body 200 are relatively moved in a direction away from each other such that all of the flexible display screen 300 is exposed to the first side of the electronic device 10. At this time, the entire flexible display 300 forms the display surface of the electronic device 10, and thus the display area of the electronic device 10 is the largest.

It will be appreciated that the intermediate state of the flexible display 300 may be varied. For example, the maximum movement distance that the first body 100 and the second body 200 can reach in the direction away from each other is H. In practical applications, the first body 100 and the second body 200 can move away from each other in the folded state to reach different movement distances of H/4, H/2, 3H/4, and the like. Accordingly, the extended length of the flexible display 300 is also different, so that the flexible display 300 is in an intermediate state of different extended lengths.

In the description of the present application, it is to be understood that terms such as "first", "second", and the like are used merely to distinguish one similar element from another, and are not to be construed as indicating or implying relative importance or implying any indication of the number of technical features indicated.

Referring to fig. 4 and fig. 5, fig. 4 is a cross-sectional view of the electronic device 10 shown in fig. 3 taken along a direction P1-P2, and fig. 5 is an enlarged view of a region a in the cross-sectional view shown in fig. 4.

The electronic device 10 further includes a conductive member 500, and the conductive member 500 is fixed to the second body 200 or the flexible display 300. In practical applications, the conductive member 500 may be fixedly connected to the second body 200 or the flexible display 300, and disposed toward the first body 100, and may contact the first body 100. For example, the first body 100 has a first surface 110 facing the flexible display 300, and the flexible display 300 has a second surface 310 facing the first body 100. In practical applications, the first surface 110 is a surface facing the inside of the electronic device 10; most of the second surface 310 can be observed by a user, i.e., is a display surface, while a portion of the second surface 310 is blocked by the first body 100. The conductive member 500 may be connected to the second surface 310 of the flexible display 300, and may be fixedly connected to the second surface 310 by welding, adhering, clamping, and the like, and the conductive member 500 is disposed toward the first body 100 and can contact the first surface 110. It can be understood that since the conductive member 500 needs to be in contact with the first body 100, the conductive member 500 may be connected to a portion of the second surface 310 shielded by the first body 100. In some embodiments, the conductive member 500 may be a signal brush, for example, a signal brush formed of a metal material. In other embodiments, the conductive member 500 may also be a probe, for example, a probe formed of a metal material.

Therefore, when the second body 200 moves relative to the first body 100, the flexible display 300 can be driven to expand or contract, and the flexible display 300 simultaneously drives the conductive member 500 to move, so that the conductive member 500 can contact with different parts of the first surface 110.

In the embodiment of the present application, a plurality of conductive regions with different electric potentials are disposed on the first body 100, for example, the plurality of conductive regions may be disposed on the first surface 110. When the second body 200 moves relative to the first body 100, the conductive member 500 can contact different conductive regions, so that the conductive member 500 and the contacted conductive regions have the same potential. It is understood that the first body 100 may include a plurality of power sources each having a different output voltage. For example, each voltage output terminal on the motherboard capable of outputting different voltages can be regarded as a power supply. In practical applications, each conductive region on the first body 100 can be electrically connected to a power source, so that a plurality of conductive regions with different potentials can be formed.

Meanwhile, in the embodiment of the present application, the processor 400 is electrically connected to the conductive member 500. For example, the conductive member 500 may be electrically connected to a motherboard of the electronic device 10 through a metal dome, and then electrically connected to the processor 400 through a printed circuit on the motherboard. It is understood that the electrical connection between processor 400 and conductive member 500 may be achieved in a variety of ways, and the above examples are merely exemplary and are not intended to limit the manner in which the two are electrically connected.

In practical applications, the processor 400 may obtain a potential of the conductive member 500, and may determine which conductive region on the first body 100 the conductive member 500 is in contact with according to the potential, so that the movement distance of the second body 200 relative to the first body 100 can be further determined according to the potential. After the movement distance is determined, the unfolding length of the flexible display screen 300 can be determined, so that the display state of the flexible display screen 300 is controlled according to the unfolding length, for example, the display interface layout of the flexible display screen 300 is adjusted, the content displayed by the flexible display screen 300 is adjusted, and the like.

It can be understood that, in practical applications, when the second body 200 moves different distances relative to the first body 100, the contact position of the conductive member 500 on the first body 100 may be determined in advance, and the conductive region may be disposed at the contact position, and the unfolding length of the flexible display 300 at this time may be determined, so as to establish a corresponding relationship between the moving distance of the second body 200 relative to the first body 100, the unfolding length of the flexible display 300, and the position of the conductive region. Accordingly, the processor 400 may determine the contacted conductive region according to the potential of the conductive member 500, thereby determining the moving distance of the second body 200 with respect to the first body 100, and further determining the unfolded length of the flexible display 300.

In some embodiments, please refer to fig. 6, where fig. 6 is a first schematic diagram illustrating a plurality of conductive regions 120 disposed on a first body of an electronic device according to an embodiment of the present disclosure.

The first body 100 is provided with a plurality of conductive regions 120, the conductive regions 120 may be electrical contacts, for example, a conductive plane may be provided on the first body 100, potentials at different positions on the conductive plane are different, and the plurality of conductive regions 120 are a plurality of electrical contacts provided on the conductive plane. The plurality of electrical contacts 120 are sequentially spaced apart. It should be noted that the adjacent electrical contacts 120 may have equal or unequal distances between them.

In some embodiments, with this arrangement, the point of suspension at which the second body 200 and the first body 100 are located can be detected. For example, it may be provided that each electrical contact 120 corresponds to a suspension point, which is the position of the second body 200 with respect to the first body 100. Processor 400 may determine whether a preset suspension point is reached according to the potential of conductive member 500, where the preset suspension point is one of the plurality of suspension points. In practical application, when a user uses the electronic device 10, the system may determine how large a display area is needed according to a currently running application or a picture to be switched to, determine a length of the flexible display screen 300 to be unfolded according to the needed display area, and determine a corresponding suspension point, which is a preset suspension point, according to the needed length. When the user stretches the electronic device 10, the processor 400 may determine whether the suspension point is reached according to the potential of the conductive member 500, so as to further determine whether the flexible display 300 is extended to a desired length.

In some embodiments, the conductive region 120 may also be a power domain plane, and a plurality of power domain planes 120 are sequentially spaced apart.

For example, referring to fig. 7, fig. 7 is a second schematic view illustrating a plurality of conductive regions 120 disposed on a first body of an electronic device according to an embodiment of the present disclosure. The conductive region 120 is a power domain plane, and the power domain planes 120 are sequentially arranged at intervals. It should be noted that the spacing distances between adjacent power domain planes 120 may be equal or unequal. In this arrangement, the conductive member 500 may be a signal brush. When the second body 200 moves relative to the first body 100, one end of the signal brush 500 can contact with different power domain planes 120, and the other end of the signal brush 500 is grounded. It should be noted that the distance between adjacent power domain planes 120 needs to be larger than the width of the signal brush 500, so as to avoid the signal brush 500 contacting two power domain planes 120 at the same time and short-circuiting the two power domain planes 120. In practical applications, each power domain plane 120 may be set to correspond to a location area, where the location area is a location of the second body 200 relative to the first body 100. The processor 400 may be configured to determine a current position region according to the potential of the conductive member 500, to determine a moving distance of the second body 200 with respect to the first body 100 according to the current position region, so that the unfolded length of the flexible display screen 300 may be further determined.

In some embodiments, please refer to fig. 8, where fig. 8 is a third schematic view illustrating a plurality of conductive regions 120 disposed on a first body of an electronic device according to an embodiment of the present disclosure. The first body 100 is provided with a conductive plane 130, and the conductive plane 130 may be a plane formed by a material such as silver, copper, aluminum, or the like. The shape, area, thickness, etc. of the conductive plane 130 can be set according to actual needs. The potential at different locations on the conductive plane 130 is different. For example, as shown in fig. 8, the second body 200 is movable in the X direction with respect to the first body 100. In the X direction, the potential of the conductive plane 130 gradually decreases or gradually increases. That is, in the X direction, the potential of the conductive plane 130 is continuously changed with the same trend.

The conductive regions 120 are electrical contacts disposed on the conductive plane 130. In some embodiments, the plurality of electrical contacts 120 may be sequentially and continuously arranged along the X direction, for example, as shown in fig. 8, and the plurality of electrical contacts 120 are sequentially connected, so that the continuous detection of the movement distance of the second body 200 relative to the first body 100 may be realized, so as to realize the real-time detection of the position of the second body 200 relative to the first body 100. It is understood that the contact area of the electrical contact 120 can be set according to the requirement, and the smaller the contact area of the electrical contact 120, the more accurate the movement distance can be detected. In practical applications, the conductive member 500 may be configured as a probe, and the contact area of the electrical contact 120 is adapted to the contact area of the probe. It should be noted that, since the electrical contacts 120 are disposed on the conductive plane 130, each electrical contact 120 may be a virtual contact on the conductive plane 130, and there is no need to form a plurality of substantial contacts on the conductive plane 130.

In practice, each electrical contact 120 may be configured to correspond to an absolute position. Wherein the absolute position is a position of the second body 200 with respect to the first body 100. The processor 400 may be configured to determine a current absolute position according to the potential of the conductive member 500, so as to determine a moving distance of the second body 200 relative to the first body 100 according to the current absolute position, that is, detect the moving distance of the second body 200 relative to the first body 100 in real time, and further determine the extended length of the flexible display screen 300.

It should be noted that, in the electronic device 10 provided in the embodiment of the present application, the arrangement positions of the conductive regions and the conductive members 500 at different potentials may be interchanged. That is, the plurality of conductive regions may be disposed at the flexible display 300, not at the first body 100. Accordingly, the conductive member 500 is fixed to the first body 100 or the second body 200. For example, the conductive member 500 may be fixedly connected to the first body 100 or the second body 200 and disposed toward the flexible display 300. In some embodiments, a plurality of conductive regions may be disposed on the second surface 310 as shown in fig. 5, while the conductive member 500 is connected to the first surface 110, and the conductive member 500 can contact the second surface 310.

In some embodiments, please refer to fig. 9, and fig. 9 is a fourth structural diagram of an electronic device 10 according to an embodiment of the present disclosure. Wherein the electronic device 10 further comprises a processing circuit 600, the processing circuit 600 may be arranged, for example, on a motherboard of the electronic device 10. Processor 400 is electrically connected to conductive member 500 through processing circuit 600. The processing circuit 600 may be used to implement functions such as filtering, voltage amplification, voltage stabilization, etc., so that the processing results of the processor 400 are more accurate.

In the electronic device 10 provided by the embodiment of the application, by providing a plurality of conductive regions with different potentials on the first body 100 and providing the conductive member 500, in the process that the second body 200 moves relative to the first body 100, the conductive member 500 can contact with the different conductive regions, so that the moving distance of the second body 200 relative to the first body 100 can be determined by the potential of the conductive member 500, and thus the extension length of the flexible display screen 300 is further determined, and therefore, the extension length of the flexible display screen 300 can be accurately detected.

The embodiment of the present application further provides a display control method, which is applied to the electronic device 10 and can be executed by the processor 400 in the electronic device 10. Referring to fig. 10, fig. 10 is a schematic flowchart illustrating a display control method according to an embodiment of the present application, where the display control method includes the following steps:

210, acquiring the potential of the conductive piece in the process of the second body moving relative to the first body;

220, determining the movement distance of the second body relative to the first body according to the electric potential;

and 230, controlling the display state of the flexible display screen according to the movement distance.

During the process that the second body 200 of the electronic device 10 moves relative to the first body 100, the processor 400 may obtain the potential of the conductive member 500, and determine the moving distance of the second body 200 relative to the first body 100 according to the potential. After the movement distance is determined, the unfolded length of the flexible display screen 300 can be determined. Accordingly, the processor 400 can control the display state of the flexible display 300, for example, adjust the display interface layout of the flexible display 300, adjust the content displayed by the flexible display 300, and the like. For the specific implementation process of each step, reference may be made to the description in each embodiment of the electronic device 10, and details are not described here.

According to the display control method provided by the embodiment of the application, the movement distance of the second body 200 relative to the first body 100 can be determined according to the potential of the conductive member 500, and the extension length of the flexible display screen 300 can be further determined, so that the extension length of the flexible display screen 300 can be accurately detected, the display state of the flexible display screen 300 can be controlled based on the extension length of the flexible display screen 300, and the accuracy of controlling the display state of the flexible display screen 300 can be improved.
