In order to solve the existing technical problems, the embodiment of the application provides a display module and electronic equipment. For better understanding of the present application, the following describes a folding screen module and an electronic device according to embodiments of the present application in detail with reference to fig. 1 to 7.
Referring to fig. 1 to 4 in combination, a folding screen module 100 is provided in an embodiment of the present application. As shown in fig. 1 to 4, the folding screen module 100 includes: the first sub-screen 10, the second sub-screen 20, the adsorption assembly 30, the drop detection assembly 40, and the controller 50.
The second sub-screen 20 is movably connected with the first sub-screen 10 and is foldable with respect to each other.
The adsorption assembly 30 is provided to at least one of the first sub-screen 10 and the second sub-screen 20.
The falling detection assembly 40 is electrically connected to the adsorption assembly 30, and is used for detecting whether the folding screen module 100 is in a falling state.
The controller 50 is electrically connected with the adsorption assembly 30, the drop detection assembly, wherein:
when the first sub-screen 10 and the second sub-screen 20 are folded and the falling detection assembly 40 detects that the folding screen module 100 falls, the controller 50 controls the adsorption assembly 30 to be in a first working state, and in the first working state, the adsorption assembly 30 is used for increasing the adsorption force between the first sub-screen 10 and the second sub-screen 20;
in the case that the falling detection assembly 40 does not detect the falling of the folding screen module 100, the controller 50 may control the adsorption assembly 30 to be in the second operating state, and in the second operating state, the adsorption assembly 30 is used to implement a target function, which is a function other than increasing the adsorption force between the first and second sub-screens 10 and 20.
The first sub-screen 10 and the second sub-screen 20 of the present application are display components of the folding screen module 100, and the first sub-screen 10 and the second sub-screen 20 can feed back some information of the folding screen module 100 to a user, and the user can also operate through the first sub-screen 10 and the second sub-screen 20 to input related information, for example, the first sub-screen 10 and the second sub-screen 20 are screens, including touch screens or non-touch screens, and also can be integral flexible screens, or locally deformable flexible screens, etc. The junction of the first sub-screen 10 and the second sub-screen 20 is a flexible screen. When the first sub-screen 10 and the second sub-screen 20 are stressed, the joints can be bent to enable the first sub-screen 10 and the second sub-screen 20 to be close to each other, and finally, the first sub-screen 10 and the second sub-screen 20 are attached together.
The folding screen module 100 has an unfolded state and a folded state, and the first sub-screen 10 and the second sub-screen 20 of the present application are folded into an inner folded state. As shown in fig. 4, in the case where the folding screen module 100 is in the inner folded state, the first and second sub-screens 10 and 20 are positioned inside the folding screen module to be protected by other members of the folding screen module 100. As shown in fig. 2 and 3, for example, the folding screen module 100 further includes a first screen 60 and a second screen 70, where the first screen 60 and the second screen 70 provide a mounting base for the first sub-screen 10 and the second sub-screen 20, and the second screen 70 is movably connected with the first screen 60 and can rotate relatively, when the folding is required, an acting force can be applied to the first screen 60 and the second screen 70 respectively, so that bending can be generated at a position where the second screen 70 is movably connected with the first screen 60, and as the bending degree increases, the first screen 60 and the second screen 70 are close to each other and drive the first sub-screen 10 and the second sub-screen 20 to be close to each other, and the first screen 60 and the second screen 70 are located outside the first sub-screen 10 and the second sub-screen 20 to protect the first sub-screen 10 and the second sub-screen 20. Alternatively, the first screen 60 and the second screen 70 may be plates, housings, or the like.
Optionally, the first sub-screen 10 and the second sub-screen 20 are folded, that is, the first sub-screen 10 and the second sub-screen 20 are arranged at an included angle, and the included angle ranges from 0 ° to 90 °, excluding the end point value.
The adsorption assembly 30 of the present application is an assembly that can achieve an increase in the adsorption force between the first sub-screen 10 and the second sub-screen 20. For example, the adsorption assembly 30 may be magnetic blocks 323 disposed in the first sub-screen 10 and the second sub-screen 20, and in the case that the falling detection assembly 40 does not detect the falling of the folding screen module 100, a magnetism blocking member is disposed between the magnetic blocks 323 disposed on the first sub-screen 10 and the second sub-screen 20, and the existence of the magnetism blocking member blocks the adsorption force between the magnetic blocks 323; under the condition that the falling detection assembly 40 detects that the folding screen module 100 falls, the magnetism isolating pieces shift, so that the magnetism blocks 323 attract each other, the adsorption force between the first sub-screen 10 and the second sub-screen 20 is increased, the first sub-screen 10 and the second sub-screen 20 are adsorbed more tightly, and the first sub-screen 10 and the second sub-screen 20 are protected. Alternatively, for example, the adsorption assembly 30 may be magnetic induction coils provided in both the first sub-screen 10 and the second sub-screen 20, and in the case where the falling detection assembly 40 does not detect the falling of the folding screen module 100, the magnetic induction coils provided on the first sub-screen 10 and the second sub-screen 20 are not energized, and the magnetic induction coils do not generate a magnetic field; under the condition that the falling detection assembly 40 detects that the folding screen module 100 falls, the magnetic induction coils on the first sub-screen 10 and the second sub-screen 20 are electrified, and the magnetic induction coils on the first sub-screen 10 and the second sub-screen 20 flow through different currents, at the moment, magnetic fields in different directions can be generated in the corresponding magnetic induction coils, and the magnetic fields are mutually attracted, so that the adsorption force between the first sub-screen 10 and the second sub-screen 20 is increased, the first sub-screen 10 and the second sub-screen 20 are adsorbed more tightly, and the first sub-screen 10 and the second sub-screen 20 are protected.
The drop detection assembly 40 of the present application may be any assembly capable of detecting whether the folding screen module 100 is in a dropped state. For example, the fall detection assembly 40 may be a gesture sensor, which may include a gravity sensor. The gravity sensor works according to the principle of piezoelectric effect. The piezoelectric effect means that an external force applied to a crystal by a heteropolar crystal having no center of symmetry will change the polarization state of the crystal and establish an electric field inside the crystal in addition to the deformation of the crystal. This phenomenon of polarization of the medium due to mechanical forces is known as the "positive piezoelectric effect". The gravity sensor uses crystal deformation caused by internal acceleration. Since such deformation generates a voltage, the acceleration can be converted into a voltage output as long as the relationship between the generated voltage and the applied acceleration is calculated. Of course, there are many other methods to fabricate acceleration sensors, such as capacitive effects, thermal bubble effects, and optical effects. In the embodiment provided by the application, the acceleration of the folding screen module 100 is detected by the gravity sensor, and whether the folding screen module 100 is in a falling state is judged by the acceleration information. Alternatively, for example, the drop detection assembly 40 may be a speed sensor that detects whether the folding screen module 100 is in a dropped state, and in the case where the acceleration of the folding screen module 100 detected by the drop detection assembly 40 through the speed sensor is close to the gravitational acceleration, it is determined that the folding screen module 100 is in the dropped state.
And a controller 50, wherein the controller 50 controls the output of the data of the adsorption assembly 30 and the drop detection assembly and the control variation through signals so as to switch the adsorption assembly 30 between the first state and the second state.
Under the condition that the falling detection assembly 40 does not detect the falling of the folding screen module 100, the adsorption assembly 30 can achieve the target function, wherein when the adsorption assembly 30 is a magnetic induction coil, the current of the magnetic induction coil disappears, the corresponding magnetic field disappears, the target function is a charging function and can also be a NFC (Near Field Communication) function, and meanwhile, the first sub-screen 10 and the second sub-screen 20 are easier to expand.
In the embodiment of the present application, the folding screen module 100 is provided with the adsorption assembly 30, the drop detection assembly 40 and the controller 50, the controller 50 is electrically connected with the adsorption assembly 30 and the drop detection assembly 40, and when the drop detection assembly 40 detects that the folding screen module 100 drops, the controller 50 receives an electrical signal of the drop detection assembly 40 and transmits an execution command to the adsorption assembly 30, and the adsorption assembly 30 is in different working states under the control of the controller 50. In this way, the first sub-screen 10 and the second sub-screen 20 in the folding screen module 100 are in a folded state, and the controller 50 controls the adsorption assembly 30 to increase the adsorption force between the first sub-screen 10 and the second sub-screen 20 when the falling detection assembly 40 detects that the folding screen module 100 falls, so that the first sub-screen 10 and the second sub-screen 20 are adsorbed more tightly, and when the folding screen module 100 receives an impact force due to falling, the expansion of the first sub-screen 10 and the second sub-screen 20 can be avoided or reduced to a certain extent, and the damage of the first sub-screen 10 and the second sub-screen 20 is prevented.
In some alternative embodiments, the adsorption assembly 30 includes:
an adsorbed member 32 provided in one of the first sub-screen 10 and the second sub-screen 20;
an absorbing member 31 provided to the other of the first sub-screen 10 and the second sub-screen 20, wherein:
when the first sub-screen 10 and the second sub-screen 20 are folded and the falling detection assembly 40 detects that the folding-screen module 100 falls, the adsorbed piece 32 is disposed opposite to the adsorbing piece 31, and the controller 50 controls the adsorbing piece 31 to adsorb the adsorbed piece 32.
In these alternative embodiments, the adsorbing assembly 30 includes the adsorbed piece 32 and the adsorbing piece 31, and in the folded state of the first sub-screen 10 and the second sub-screen 20, the adsorbed piece 32 is opposite to the adsorbing piece 31, so as to ensure that the adsorbed piece 32 and the adsorbing piece 31 have a higher adsorption force.
Alternatively, the adsorbing assemblies 30 are multiple groups of adsorbing assemblies 30, each group of adsorbing assemblies 30 includes at least one adsorbed piece 32 and at least one adsorbing piece 31, and the at least one adsorbed piece 32 and the at least one adsorbing piece 31 are disposed opposite to each other. The first sub-screen 10 and the second sub-screen 20 are tightly adsorbed under the action of the adsorption component 30, so that the folding screen module 100 is better protected, and the risk of damage to the sub-screen in the falling process is reduced.
Optionally, the adsorbed piece 32 is located at an end of the first sub-screen 10 or the second sub-screen 20 away from the movable connection of the first sub-screen 10 and the second sub-screen 20, and the adsorbed piece 31 is located at an end of the first sub-screen 10 or the second sub-screen 20 away from the movable connection of the first sub-screen 10 and the second sub-screen 20. Compared with the movable connection part of the first sub-screen 10 and the second sub-screen 20, the end part of the first sub-screen 10 and the second sub-screen 20 far away from the connection part is easier to be unfolded under the condition of external acting force, so that the position of the adsorption component 30 is designed more reasonably, and the adsorption effect achieved by the adsorption component 30 can be ensured.
Alternatively, the member 32 may be a member having no adsorption ability, such as a metal block; alternatively, the magnetic sensor may be a component having an adsorption capability, such as a magnet, or a magnetic induction coil and a switch assembly.

the first switch assembly 312 is electrically connected to the controller 50, and the first switch assembly 312 is connected to the first circuit path and connected in series with the first magnetic induction coil 311, wherein:
when the first sub-screen 10 and the second sub-screen 20 are folded and the falling detection assembly 40 detects that the folded-screen module 100 falls, the first magnetic induction coil 311 is disposed opposite to the adsorbed piece 32, and the controller 50 controls the first switch assembly 312 to be turned off, so that the first current path flows through the first magnetic induction coil 311.
In these alternative embodiments, the adsorbing member 31 includes a first magnetic induction coil 311 and a first switch assembly 312, and by using the principle of the magnetic effect of the oersted current, when the falling detection assembly 40 detects that the folding screen module 100 falls, the controller 50 controls the first switch assembly 312, the first switch assembly 312 connects the first circuit path with the first magnetic induction coil 311, the first magnetic induction coil 311 with the current generates a certain magnetic field to adsorb the adsorbed member 32, so that the first sub-screen 10 and the second sub-screen 20 are adsorbed more tightly based on the adsorption force of the adsorbing member 31, thereby effectively reducing the risk of the sub-screen being damaged during the falling process. Under the condition that the falling detection assembly 40 does not detect that the folding screen module 100 falls, the controller 50 can control the first switch assembly 312 to disconnect the first circuit path from the first magnetic induction coil 311, the first magnetic induction coil 311 does not pass through current, the adsorption to the adsorbed piece 32 can not be generated, and the NFC function which can be realized by the first magnetic induction coil 311 at this time can be achieved, so that the effect of one object with multiple purposes is achieved.
It should be noted that, the attracted member 32 may be a magnetic induction coil and a switch assembly having the same structure as the attracted member 31, and the attracted member 32 and the attracted member 31 need to flow currents in different directions to generate different magnetic fields. The magnetic block 323 and the like may be attracted by the first magnetic induction coil 311.
Optionally, the adsorbing member 31 further includes: the first connector and the first circuit board flexible board connecting the suction member 31 and the first magnetic induction coil 311.
Optionally, the first screen 60 is provided with a plurality of connectors, at least one of the plurality of connectors being electrically connected to the first connector. The first connector in the absorbing member is connected with at least one connector on the corresponding first screen body 60, and the position of the connector of the first screen body 60 is determined according to stacking requirements, so that the absorbing member 31 is connected with the first connector through the connector under the condition that the falling detection assembly 40 detects that the folding screen module 100 falls, and current passes through the absorbing member.
Alternatively, the first magnetic induction coil 311 is a plurality of magnetic induction wires stacked in the circumferential direction.
Optionally, the first current path includes a power supply for supplying current to the first current path and a resistor, the resistor mainly serving to protect the first current path.
In some alternative embodiments, as shown in fig. 1, 2 and 6, the adsorbate 32 comprises:
a second magnetic induction coil 321 connected to the second current path;
the second switch assembly 322 is electrically connected to the controller 50, and the second switch assembly 322 is connected to the second current path and connected in series with the second magnetic induction coil 321, wherein:
when the second sub-screen 20 and the second sub-screen 20 are folded and the falling detection assembly 40 detects that the folding screen module 100 falls, the second magnetic induction coil 321 is opposite to the first magnetic induction coil 311, and the controller 50 further controls the second switch assembly 322 to be turned off, so that the second current path flows through the second magnetic induction coil 321, and the current directions of the first magnetic induction coil 311 and the second magnetic induction coil 321 are opposite.
In these alternative embodiments, when the first sub-screen 10 and the second sub-screen 20 are folded and the falling detection component 40 detects that the folded-screen module 100 falls, the controller 50 controls the first switch component 312 of the adsorbing member 31 and the second switch component 322 of the adsorbed member 32, so that the first magnetic induction coil 311 and the second magnetic induction coil 321 are electrified, and the first magnetic induction coil 311 and the second magnetic induction coil 321 flow through currents in different directions, so as to generate magnetic fields in different directions, and according to the principle of different poles attracting, when the opposite directions of the first sub-screen 10 and the second sub-screen 20 generate different poles respectively, the first sub-screen 10 and the second sub-screen 20 are adsorbed more tightly under the action of the poles, thereby better protecting the risk of breakage of the first sub-screen 10 and the second sub-screen 20 during the falling process of the folded-screen module 100.
The first magnetic induction coil 311 and the second magnetic induction coil 321 of the present application flow currents in different directions, thereby generating magnetic fields in different directions, which can be understood as: when the current in the absorbing member 31 is in the counterclockwise direction, a corresponding magnetic field is generated in the corresponding second magnetic induction coil 321, and according to the corresponding principle of the oersted current magnetic effect, the direction of the magnetic field is the direction in which the N pole (north pole) is perpendicular to the first sub-screen 10 and away from the second sub-screen 20, and the corresponding S pole (south pole) is opposite to the N pole.
