The terminal equipment needs to judge the current state of the display screen in the starting or using process so as to determine the display mode of the display screen, avoid simultaneous lightening of a plurality of display screens, not only cause resource waste, but also be inconvenient for users to use. Moreover, since the service life of the display screen is limited, if the time of the display screen in the lighting state is too long, the service life of the display screen is shortened.
In this embodiment, at least one of the two display screens is a foldable screen, and the two display screens are arranged back to back when the foldable screen is in an unfolded state. As shown in fig. 8, for example, the terminal device includes two display screens, the two display screens are parallel to a plane formed by intersecting the X axis and the Y axis, respectively, and the two display screens are arranged back to back in the Z axis direction. Here, the back-to-back arrangement means that the light emitted from the two display panels is emitted in opposite directions when the two display panels are in the lit state.

In this embodiment, a control method of a display screen in this embodiment will be described with one of two display screens as a folding screen and the other display screen as a flat screen as an application scene of this embodiment. It is understood that the adaptation can be performed by those skilled in the art according to the actual situation.

The folding screen includes two sub-display screens. The folding screen is used as an inner screen of the terminal device, and the plane screen is used as an outer screen of the terminal device. As shown in fig. 1, the method for controlling a display screen in this embodiment includes the following steps:
and S110, acquiring data acquired by the sensors, wherein the sensors are arranged on at least one sub display screen and are used for receiving or transmitting radar waves.
Wherein the sensor is arranged on a display screen in the form of a folding screen, as shown in fig. 8, the display screen comprises a first sub-display screen 1 and a second sub-display screen 2. For example, the sensor may be disposed on the first sub-display 1, and the data measured by the sensor may be data that is shielded and reflected by the second sub-display 2 based on the signal emitted by the sensor; or, the sensor may be disposed on the second sub-display 2, and the data measured by the sensor may be data that is shielded and reflected by the first sub-display 1 based on the signal emitted by the sensor; or the first sub-display screen and the second sub-display screen are respectively provided with a sensor, the sensors of the first sub-display screen and the second sub-display screen can be correspondingly arranged or staggered, and the data collected by the sensors can be average data obtained after comprehensive calculation according to the data respectively measured by the two sensors.
And step S120, determining the state of the folding screen according to the data collected by the sensor.
When the sensor is arranged on one sub-display screen, the data collected by the sensor can be relative position information between the two sub-display screens, or distance information or included angle information between the two sub-display screens, and the state of the folding screen can be determined according to the data collected by the sensor. The folded screen state may be an unfolded state or a folded state.
And S130, controlling the display states of the two display screens of the terminal equipment according to the state of the folding screen.
For example, when the foldable screen is in the unfolded state, the two sub-display screens of the foldable screen can be controlled to display synchronously or respectively, and the display screen opposite to the display screen is turned off. Or when the folding screen is in a folding state, the two sub-display screens of the folding screen can be controlled to be turned off, and the display screen opposite to the display screen displays according to the user requirement.
As shown in fig. 2, another exemplary embodiment of the present disclosure provides a control method of a display screen, including the steps of:
and S210, acquiring data acquired by a sensor, wherein the sensor is arranged on at least one sub-display screen.
In this embodiment, a sensor may be disposed on one sub-display screen, and a radar sensor may be disposed on one sub-display screen. Of course, it is understood that the detection function may be implemented using an infrared sensor or a distance sensor in addition to the radar sensor. The sub-display screen provided with the sensor can be used for digging a hole screen, a hole is formed in the sub-display screen, the position of the digging hole is not provided with the display module and the touch module, the sensor is installed at the position of the digging hole, and relevant data between the two sub-display screens of the folding screen are collected. For example, when the sensor is an infrared sensor, the infrared sensor is disposed on one of the two sub-display screens, the transmitter of the infrared sensor transmits infrared rays, the infrared rays are reflected by the other of the two sub-display screens, and the receiver of the infrared sensor receives the reflected infrared rays. Furthermore, the infrared sensor realizes the distance measurement between the two sub-display screens according to the relevant physical information of the transmitted and received infrared rays. Or the sensor can be a radar sensor, the radar sensor is arranged on one of the two sub-display screens, the radar sensor transmits radar waves, the radar waves are reflected by the other of the two sub-display screens, the radar sensor receives the reflected radar waves, and distance measurement between the two sub-display screens is realized according to relevant physical information of the transmitted and received radar waves. In addition, the radar sensor can determine the general shape and material of the detected object through the emitted radar waves.
In addition, as shown in fig. 8, the position of the sensor may be set at a position near an edge of the sub display, such as an edge extending in the length direction of the cellular phone. When the folding screen is changed from the folding state to the unfolding state, the edges of the two sub-display screens extending along the length direction of the mobile phone are firstly separated, and the sensor is arranged at the position, so that data can be quickly and accurately detected in the moment of state change of the folding screen.
And S220, determining distance information between the two sub display screens according to the data acquired by the sensor.
In one example, as shown in fig. 8, a sensor 3 is disposed on a first sub-display 1, the sensor 3 may be a radar sensor, the radar sensor emits an electromagnetic wave (radar wave), when the electromagnetic wave contacts a second sub-display 2, the radar wave is reflected by the second sub-display 2 to generate a reflected wave, the radar sensor receives the reflected wave, and distance information between the two sub-displays can be determined according to the reflected wave.
In another example, still referring to fig. 8, a sensor 3 is disposed on the first sub-display 1, the sensor 3 may be an infrared sensor, the infrared sensor emits infrared rays, when the infrared rays contact the second sub-display 2, the infrared rays are reflected by the second sub-display 2 to generate reflected light, and the infrared sensor receives the reflected light to determine distance information between the two sub-displays according to the reflected light.
And step S230, determining an included angle between the two sub display screens according to the distance information.
When the folding screen is completely unfolded, the included angle between the two sub-display screens is 180 degrees, and the distance between the two sub-display screens is the largest at the moment (the distance between the two sub-display screens refers to the distance between the position of the sensor on the sub-display screen and the position corresponding to the other sub-display screen). Under the state that the folding screen is completely folded, the included angle of the two sub-display screens is 0 degree, and the distance between the two sub-display screens is 0 at the moment. According to the change rule, the included angle between the two sub display screens can be determined according to the distance between the two sub display screens.
And S240, determining the state of the folding screen according to the included angle.
In order to control the display modes of the two display screens conveniently, the states of the folding screen are divided into an unfolding state and a folding state, and when an included angle between the two sub display screens of the folding screen meets a first condition, for example, the included angle between the two sub display screens is in a range of 0-30 degrees, the folding screen is considered to be in the folding state. When the included angle between the two sub-display screens of the folding screen meets a second condition, for example, the included angle between the two sub-display screens is greater than 30 degrees, the folding screen is considered to be in the unfolded state. Here, the above numerical values are merely used to describe the control method in the present embodiment, and are not used as specific determination numerical values for the folded state.
And step S250, controlling the display states of the two display screens of the terminal equipment according to the state of the folding screen.
For example, when the folding screen is in the unfolded state, the two sub-display screens of the display screen are controlled to display synchronously or respectively, and the display screen opposite to the display screen is turned off. When the folding screen is in a folding state, the two sub-display screens of the display screen are controlled to be turned off, and the display screen opposite to the display screen displays.
As shown in fig. 3, another exemplary embodiment of the present disclosure provides a control method of a display screen, including the steps of:
and S310, acquiring data acquired by the sensor, wherein the sensor is arranged on at least one sub display screen.
In the embodiment, the sensor emits a signal at preset time intervals, for example, emits a signal at 30ms intervals, so as to continuously detect the distance between the two sub-display screens, thereby ensuring that the distance between the two sub-display screens can be continuously obtained in the subsequent process, and ensuring the detection accuracy and reliability.
The method for selecting the sensor and the method for acquiring data by using the sensor in the embodiment are the same as those in the above embodiments, and are not described herein again.
And step S320, determining distance information between the two sub display screens according to the data acquired by the sensor.
In one example, as shown in fig. 8, a sensor 3 is disposed on the first sub-display 1, and the sensor 3 may be a radar sensor, and the distance information between the two sub-displays is determined according to the radar sensor.
Step S330, first configuration information is obtained, and the first configuration information is used for representing the mapping relation between the distance information and the included angle.
When the included angle between the two sub display screens is 180 degrees, the distance between the two sub display screens is the largest; when the included angle of the two sub-display screens is 0 degree, the distance between the two sub-display screens is the minimum. According to the relationship between the distance and the included angle between the sub display screens, the mapping relationship between the distance information and the included angle information, namely first configuration information, can be set, the first configuration information can be stored in a memory in advance, and the first configuration information can be modified or supplemented according to actual conditions.
And step S340, determining an included angle corresponding to the distance information according to the first configuration information and the distance information.
According to data collected by the sensor, a distance value between the two sub display screens in the current state detected by the sensor can be determined, and according to the first configuration information, an included angle corresponding to the distance value can be determined in the first configuration information in a traversing mode or an indexing mode.
And step S350, determining the state of the folding screen according to the included angle.
In an exemplary embodiment, the state of the folding screen is determined according to the included angle by: and setting a preset angle threshold corresponding to the folding screen state, and comparing the relation between the included angle and the preset angle threshold.
When the included angle is smaller than or equal to the preset angle threshold, it is determined that the folding screen is in the folding state, for example, the preset angle threshold is set to a fixed value, for example, 30 °, and when the included angle is smaller than or equal to 30 °, it is determined that the folding screen is in the folding state. When the included angle is larger than a preset angle threshold value, determining that the folding screen is in an unfolded state; for example, when the included angle is larger than 30 degrees, the folding screen is determined to be in the unfolding state.
Or when the included angle is smaller than a preset angle threshold value, determining that the folding screen is in a folding state; for example, when the included angle is less than 30 degrees, the folding screen is determined to be in the folding state. When the included angle is larger than or equal to a preset angle threshold value, determining that the folding screen is in an unfolded state; for example, when the included angle is greater than or equal to 30 degrees, the folding screen is determined to be in the folding state.
In another exemplary embodiment, the preset angle threshold may also be an angle range interval, for example, when the included angle is smaller than the [30 °, 45 ° ] interval, it is determined that the folding screen is in the folded state, and when the included angle is larger than the (45 °, 60 ° ] interval, it is determined that the folding screen is in the unfolded state.
In another exemplary embodiment, the corresponding relationship between the unfolded state and the preset angle threshold may be further refined, for example, when the included angle is located in the interval of [0 °, 30 ° ], it is determined that the folding screen is in the folded state; when the included angle is positioned in the interval of (30 degrees and 90 degrees), the folding screen is determined to be positioned in the first unfolding state, and when the included angle is positioned in the interval of (90 degrees and 180 degrees), the folding screen is determined to be positioned in the second unfolding state.
And S360, controlling the display states of the two display screens of the terminal equipment according to the state of the folding screen.
In an exemplary embodiment, when the folding screen is in a folding state, the folding screen is controlled to be displayed in a first display state, and the other display screen of the two display screens is controlled to be displayed in a second display state; the first display state is a turned-off state, and the second display state is a turned-on state.

In another exemplary embodiment, when the folding screen is in the folded state, the folding screen is controlled to be displayed in an off state, and the other of the two display screens is controlled to be displayed in an on state. When the folding screen is in the first unfolding state, the folding screen (the two sub-display screens can synchronously display or respectively display pictures) is controlled to be lightened at a first brightness, and the other display screen of the two display screens is controlled to be displayed in a blank state.

As shown in fig. 4, another exemplary embodiment of the present disclosure provides a control method of a display screen, including the steps of:
and S410, acquiring data acquired by the sensor, wherein the sensor is arranged on at least one sub-display screen.
In one example, as shown in fig. 8, a sensor 3 is provided on the first sub display 1, the sensor being a radar sensor. In addition to detecting the distance between the two sub-display screens, the radar sensor in this embodiment may determine the shape and material of the detected object (i.e., the sub-display screen or other obstacle blocking the radar wave) according to the reflected wave of the emitted radar wave, so as to ensure that the data obtained by detecting the second sub-display screen 2 as the blocking object is controlled in the subsequent method step execution process, improve the accuracy of the control method, and avoid mistakenly controlling the data acquired by detecting the sensor by using other objects (such as fingers) as the blocking object.
Step S420, determining material information of a target object according to the data acquired by the sensor, wherein the target object is an object for shielding signals sent by the sensor. And determining whether the target object is a display screen or not according to the material information.
The radar sensor measures information by emitting an electromagnetic wave and receiving a reflected wave from a target object, and if the target object is made of a different material, information such as the frequency or velocity of the reflected wave changes. The screen layer of the display screen is determined, so that the information of the radar waves which can be reflected by the display screen is determined. Referring to fig. 8, according to the data collected by the radar sensor located in the first sub-display screen 1, it can be determined whether the received reflected wave data is from the second sub-display screen, and if so, the state of the folding screen can be determined according to the distance data collected by the radar sensor.
When other shelters except the second sub-display screen 2 shelter from the radar wave emitted by the radar sensor, for example, when a finger blocks the radar wave emitted by the sensor 3 arranged on the first sub-display screen 1, the signal collected in the collection process can be ignored, and the signal is collected again until the signal reflected back by the second sub-display screen is collected, and then the subsequent control steps are carried out.
