Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to fall within the scope of the application.

The embodiment of the application provides electronic equipment and a display control method. The display control method can be applied to the electronic equipment, namely, an execution subject 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 diagram of a first structure of an electronic device 10 according to an embodiment of the application. 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, a cellular telephone, a media player, or other handheld or portable electronic device, a smaller device (such as a wristwatch device, a hanging device, a headset or earpiece device, a device embedded in glasses or other device worn on the head of a user, or other wearable or miniature device), a television, a computer display not containing 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 automobile), a device implementing the functionality of two or more of these devices, or other electronic device. In the exemplary configuration of fig. 1, the electronic device 10 is a portable device such as a cellular telephone, media player, tablet, 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 with the first body 100, and the other end of the flexible display screen 300 is connected with 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 be, but not limited to, fixedly connected to the first body 100 or the second body 200 through a connecting member (such as a driving belt and a driving rack). The processor 400 may be disposed in the first body 100 or may be disposed in the second body 200. For example, a motherboard on which the processor 400 is disposed may be disposed within the first body 100. The processor 400 may be, for example, an application processor (Application Processor, AP). The processor 400 may be used to perform various functions of the electronic device 10 and process data to provide overall monitoring of the electronic device 10.

It will be appreciated that the first body 100, the second body 200 may provide support for the electronics in the electronic device 10 to mount the electronics in the electronic device 10 together. For example, the first body 100 and the second body 200 may support the flexible display screen 300. For another example, the electronic devices such as a camera, a receiver, a circuit board, a power source, etc. in the electronic apparatus 10 may be mounted to 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 drawer or comb-like structure. It is understood that the first body 100 and the second body 200 may be, but not limited to, a sliding or sliding structure including a sliding rail, a slideway, etc., so that the second body 200 can move relative to the first body 100. Thus, the user can perform sliding, drawing, etc. operations on the first body 100, the second body 200 to realize the relative movement of the first body 100, the second body 200.

Wherein the first body 100 and the second body 200 may relatively move in a direction approaching or separating 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 is driven to expand or contract, so that the expansion length of the flexible display screen 300 is changed accordingly. The unfolding length of the flexible display screen 300 is the same as or in a certain conversion relation with the movement 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 unfolding length of the flexible display screen 300 may be L or a certain conversion relationship between the unfolding length and L exists. Thus, by detecting the movement distance of the second body 200 with respect to the first body 100, the unfolded length of the flexible display screen 300 can be accurately detected. Further, the electronic device 10 may control the display state of the flexible display 300 according to the extended length of the flexible display 300, for example, adjust the layout of the display interface of the flexible display 300, adjust the content displayed by the flexible display 300, and so on.

It will be appreciated that the flexible display 300 can be switched between the first configuration and the second configuration as 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 the other of the expanded state, the intermediate state, and the collapsed state. Thus, the flexible display 300 can be switched between any two of the unfolded state, the intermediate state, and the folded state.

Fig. 1 is a schematic view of a flexible display 300 in a collapsed state. The folded state may be a state in which the first body 100 and the second body 200 are moved relatively in a direction approaching each other to be finally formed. For example, the electronic device 10 may include first and second opposite sides, 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 300 is in the collapsed state, a portion of the flexible display 300 may be located on a first side of the electronic device 10 and a portion of the flexible display 300 may be located on a second side of the electronic device 10. It will be appreciated 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, etc. The portion of the flexible display 300 located 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 diagram of a second structure of the electronic device 10 according to the embodiment of the application. 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 screen 300 is partially located at the first side of the electronic device 10 and partially located at the 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 within the electronic device 10. It will be appreciated that the portion of the flexible display 300 on the first side of the electronic device 10 increases and the portion on the second side of the electronic device 10 correspondingly decreases relative to the collapsed state, thereby increasing the display area of the electronic device 10.

Referring to fig. 3, fig. 3 is a schematic diagram of a third structure of the electronic device 10 according to the embodiment of the application. 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 apparatus 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 maximized.

It will be appreciated that there may be a variety of intermediate states of the flexible display 300. 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 achieve different movement distances of H/4, H/2, 3H/4, etc. Accordingly, the extended lengths of the flexible display 300 are also different, thereby causing the flexible display 300 to form an intermediate state of different extended lengths.

In the description of the present application, it should be understood that terms such as "first," "second," and the like are used merely to distinguish between similar objects and should not be construed to indicate or imply relative importance or implying any particular order of magnitude of the technical features indicated.

Referring to fig. 4 and 5, fig. 4 is a cross-sectional view of the electronic device 10 shown in fig. 3 along the direction P1-P2, and fig. 5 is an enlarged schematic view of a portion 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 with the second body 200 or the flexible display 300, and disposed towards the first body 100, and can contact with 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 interior of the electronic device 10; a majority of the second surface 310 can be observed by a user, i.e., a display surface, while a portion of the second surface 310 is obscured by the first body 100. The conductive element 500 may be connected to the second surface 310 of the flexible display screen 300, for example, may be fixedly connected to the second surface 310 by welding, adhering, clamping, or the like, and meanwhile, the conductive element 500 is disposed towards the first body 100 and can contact the first surface 110. It will be appreciated that since the conductive member 500 is required to contact the first body 100, the conductive member 500 may be attached to a portion of the second surface 310 that is shielded by the first body 100. In some embodiments, the conductive member 500 may be a signal brush, such as a signal brush made of metal. In other embodiments, the conductive member 500 may be a probe, such as a probe made of metal.

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

In an embodiment of the present application, a plurality of conductive areas with different electric potentials are disposed on the first body 100, for example, the plurality of conductive areas may be disposed on the first surface 110. The conductive member 500 can be contacted with different conductive regions when the second body 200 moves relative to the first body 100, so that the conductive member 500 has the same potential as the contacted conductive region. It is understood that the first body 100 may include a plurality of power sources, each of which has 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 area on the first body 100 may be electrically connected to a power source, so as to form a plurality of conductive areas with different potentials.

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 the motherboard of the electronic device 10 through a metal spring, and then electrically connected to the processor 400 through a printed circuit on the motherboard. It will be appreciated that the electrical connection of the processor 400 to the conductive member 500 may be accomplished in a variety of ways, and the above examples are merely exemplary and are not intended to limit the manner in which the two may be electrically connected.

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

It can be appreciated that in practical applications, the contact position of the conductive member 500 on the first body 100 when the second body 200 moves different distances relative to the first body 100 may be measured in advance, and the conductive area is set at the contact position, and the unfolding length of the flexible display 300 at this time is measured, so that the correspondence relationship between the movement 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 area is established. Thus, the processor 400 can determine the contacted conductive area according to the potential of the conductive member 500, thereby determining the movement distance of the second body 200 relative to the first body 100, and further determining the unfolded length of the flexible display 300.

In some embodiments, referring to fig. 6, fig. 6 is a first schematic diagram of a first body of an electronic device provided with a plurality of conductive areas 120 according to an embodiment of the application.

The first body 100 is provided with a plurality of conductive areas 120, and the conductive areas 120 may be electrical contacts, for example, a conductive plane may be disposed on the first body 100, and the electrical potentials at different positions on the conductive plane are different, and the plurality of conductive areas 120 are a plurality of electrical contacts disposed on the conductive plane. The plurality of electrical contacts 120 are sequentially spaced apart. The pitches between the adjacent electrical contacts 120 may be equal or unequal.

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

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

For example, referring to fig. 7, fig. 7 is a second schematic diagram of the electronic device according to the embodiment of the application, in which a plurality of conductive areas 120 are disposed on a first body. The conductive area 120 is a power domain plane, and the power domain planes 120 are sequentially spaced apart. The distance between adjacent power domain planes 120 may be equal or unequal. In this arrangement, the conductive member 500 may be a signal brush. Wherein, when the second body 200 moves relative to the first body 100, one end of the signal brush 500 can contact with the different power domain planes 120, and the other end of the signal brush 500 is grounded. It should be noted that, the distance between the 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 the two power domain planes 120 at the same time and shorting the two power domain planes 120. In practical applications, it may be configured that each power domain plane 120 corresponds to a location area, where the location area is a position of the second body 200 relative to the first body 100. The processor 400 may be configured to determine a current location area according to the potential of the conductive member 500, so as to determine a movement distance of the second body 200 relative to the first body 100 according to the current location area, so that the unfolded length of the flexible display screen 300 may be further determined.

In some embodiments, referring to fig. 8, fig. 8 is a third schematic diagram illustrating a first body with a plurality of conductive areas 120 disposed thereon in an electronic device according to an embodiment of the application. The first body 100 is provided with a conductive plane 130, and the conductive plane 130 may be, for example, a plane formed of a material such as silver, copper, aluminum, or the like. The shape, area, thickness, etc. of the conductive plane 130 may 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, the potential of the conductive plane 130 is continuously changed in the X direction, and the change trend is the same.

Wherein the plurality of conductive areas 120 are a plurality of electrical contacts disposed on the conductive plane 130. In some embodiments, the plurality of electrical contacts 120 may be sequentially disposed in succession along the X direction, for example, as shown in fig. 8, where the plurality of electrical contacts 120 are sequentially connected, so as to enable continuous detection of the movement distance of the second body 200 relative to the first body 100, so as to enable real-time detection of the position of the second body 200 relative to the first body 100. It will be appreciated that the contact area of the electrical contact 120 may be set as desired, the smaller the contact area of the electrical contact 120, the more accurate the distance of movement that can be detected. In practical applications, the conductive member 500 may be configured as a probe, where 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, without forming a plurality of substantial contacts on the conductive plane 130.

In practice, it may be provided that each electrical contact 120 corresponds to an absolute position. The absolute position is a position of the second body 200 relative to the first body 100. The processor 400 may be configured to determine the current absolute position according to the potential of the conductive member 500, so as to determine the movement distance of the second body 200 relative to the first body 100 according to the current absolute position, that is, detect the movement distance of the second body 200 relative to the first body 100 in real time, so that the unfolding length of the flexible display screen 300 may be further determined.

In the electronic device 10 according to the embodiment of the present application, the positions of the conductive areas with different electric potentials and the conductive member 500 may be interchanged. That is, a plurality of conductive areas may be provided to the flexible display screen 300 instead of 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 with the first body 100 or the second body 200 and disposed toward the flexible display screen 300. In some embodiments, a plurality of conductive areas may be provided on the second surface 310 shown in fig. 5, while the conductive member 500 is connected to the first surface 110, and the conductive member 500 is capable of contacting the second surface 310.

In some embodiments, referring to fig. 9, fig. 9 is a schematic diagram of a fourth structure of an electronic device 10 according to an embodiment of the application. The electronic device 10 further comprises a processing circuit 600, wherein the processing circuit 600 may be arranged on a motherboard of the electronic device 10, for example. The processor 400 is electrically connected to the conductive member 500 through the processing circuit 600. Processing circuit 600 may be used to perform functions such as filtering, voltage amplification, voltage regulation, etc., to make the processing results of processor 400 more accurate.

In the electronic device 10 provided by the embodiment of the application, the plurality of conductive areas with different electric potentials are arranged on the first body 100, and the conductive piece 500 is arranged, so that the conductive piece 500 can be in contact with the different conductive areas in the process of moving the second body 200 relative to the first body 100, and the moving distance of the second body 200 relative to the first body 100 can be determined by the electric potential of the conductive piece 500, so that the unfolding length of the flexible display screen 300 is further determined, and the unfolding length of the flexible display screen 300 can be accurately detected.

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

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

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

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

During the movement of the second body 200 of the electronic device 10 relative to the first body 100, the processor 400 may obtain the electric potential of the conductive member 500, and determine the movement distance of the second body 200 relative to the first body 100 according to the electric potential. After determining the movement distance, the deployment length of the flexible display 300 may be determined. Thus, the processor 400 may control the display state of the flexible display 300, such as adjusting the layout of the display interface of the flexible display 300, adjusting the content displayed by the flexible display 300, and so on. The specific implementation process of each step may refer to the description in each embodiment of the electronic device 10, which is not repeated herein.
