Detailed Description
Generally, an electronic device has an automatic rotation function of a display screen, and the automatic rotation function can be turned on and off by a function selection switch on the electronic device. Fig. 1A is a schematic diagram of an automatic display screen switching switch in the related art, and as shown in fig. 1A, an automatic rotary switch 12 exists in a pull-down menu of a display interface 11 of an electronic device, and automatic switching between horizontal and vertical screens can be achieved through operation of the switch 12. In the related art, a gyroscope and an acceleration sensor are mainly used for realizing automatic switching of horizontal and vertical screens. The acceleration sensor measures linear acceleration in the three-axis direction, and the gyroscope measures angular acceleration in the three-axis direction. The gyroscope and the acceleration sensor are commonly used sensors in intelligent electronic equipment, and at present, more two-in-one schemes of the two sensors are adopted. The acceleration sensor can equivalently detect the motion direction of the electronic equipment, namely the gesture detection applied to the electronic equipment. The electronic equipment can only detect the axial motion by the acceleration sensor, but can not measure the rotational motion, and the gyroscope can measure the rotational motion and the deflection motion of the electronic equipment, so that the actual motion of a user can be accurately analyzed, and application development is carried out on the basis.
Fig. 1B is a schematic diagram of a specific usage scenario of an electronic device in the related art, as shown in fig. 1B, in the use of some specific scenarios, such as holding the electronic device with a horizontal screen on both sides as shown in a circular frame 101 for video appreciation or game operation, once the body moves slightly (turns over or rises), the electronic device may turn horizontally and slightly, and at this time, the screen of the electronic device may change from the horizontal screen to the vertical screen, which disturbs the immersive experience effect of the user. Fig. 1C is a schematic diagram of a specific usage scenario of an electronic device in the related art, as shown in fig. 1C, when some specific scenarios are used, for example, when the electronic device is operated by two hands standing on a screen as shown in a circular frame 111, the electronic device is suddenly laid flat by being held by two hands, and a flipping of the video interface may also occur, but the user does not intend to flip at this time.
Therefore, the embodiment of the application provides a new display screen switching method, which can be implemented by determining the positions of N sensing areas receiving pressure on an electronic device and sensing parameter values corresponding to each sensing area, wherein N is a natural number greater than 1; determining a first direction of the display screen according to the positions of the N sensing areas and sensing parameter values corresponding to the N sensing areas; and switching the state of the display screen according to the first direction. Therefore, the direction of the display screen of the electronic equipment can be determined according to the position of the sensing area receiving the pressure in the electronic equipment and the sensing parameters corresponding to the sensing area, and the problem that the horizontal and vertical screen switching of the display screen under a part of specific scenes in the related art is not in line with the actual requirements of users is solved. In addition, the switching method of the display screen can be combined with a method of switching by using a gravity sensor (namely, an acceleration sensor is combined with a gyroscope) in the related art, so that the horizontal and vertical screen switching which accurately and better meets the requirements of users can be realized.

In addition, under different use scenes, the pressure, the pressing area and the pressing time length received by the sensing area are also different. When the user holds the electronic device with the gesture shown in fig. 1C, the sensing areas on two symmetrical sides of the electronic device are pressed and receive pressure. And the pressure magnitude and the pressing area on different symmetrical sensing areas are also different.
Step S203, switching the state of the display screen according to the first direction; the display screen comprises a horizontal screen and a vertical screen.
In some embodiments, if the state of the display screen of the electronic device is a landscape screen and the first direction is a portrait screen, the state of the display screen is switched to a portrait screen. And if the state of the display screen of the electronic equipment is a transverse screen and the first direction is the transverse screen direction, keeping the state of the display screen unchanged.

In some embodiments, the N sensing regions are located on a side frame of the electronic device.
In some embodiments, the electronic device may include M sensing regions, where the M sensing regions are all located on a side frame of the electronic device, M is a natural number greater than 1, and M is greater than or equal to N.
Of course, the N sensing regions may also be located on a side of the electronic device opposite to the display screen and on the side frame.

The method and the device for detecting the direction of the display screen comprise the steps that the direction of the display screen is detected by combining an acceleration sensor and a gyroscope, when the direction of the display screen is detected to be changed from a transverse screen to a vertical screen (or the direction of the display screen is changed from the vertical screen to the transverse screen), the state of the display screen is not switched, and the positions of N induction areas receiving pressure on the electronic equipment and induction parameter values corresponding to the induction areas are continuously determined.
That is, after the horizontal and vertical screen switching state of the electronic device is detected by using the acceleration sensor in combination with the gyroscope, if the switching condition is met, the switching is not performed, but the position of the sensing area receiving the pressure and the sensing parameter value corresponding to the sensing area are continuously used for performing auxiliary judgment on the direction of the display screen.

In some embodiments, the usage scenario includes at least one of: game type scenes, social chat type scenes, video type scenes, reading type scenes and navigation type scenes.
In some embodiments, before the determining the current usage scenario of the electronic device, the method further comprises: and determining corresponding preset pressure values and preset noise values of the electronic equipment under different use scenes through machine learning and model training.
In some embodiments, the sensing parameter values include: the pressure of the press; or, the pressure of the press and the area of the press; or the pressure of the press, the area of the press and the length of the press.

Certainly, consider that the horizontal screen of different electronic equipment holds the state different, can define the induction zone that the pressure button can be pressed under the different use scenes according to user's in-service use condition, through detecting information such as press zone size, dynamics of pressing and duration length of pressing, pressure sensor reports the state to the software application layer, judges that electronic equipment is in the state of horizontal/vertical screen this moment, increases the logical judgement of software: the electronic device is used for horizontal/vertical screen at this time, and in a preset time range, even if the angle is larger than the preset angle, vertical/horizontal screen operation is not performed temporarily.
The related pressure keys on the side edges are mainly of a piezoresistive type, a display screen TP (Touch Panel) principle type (namely, capacitance Touch), an ultrasonic wave combined piezoresistive type and the like. Fig. 5A is a schematic diagram of a piezoresistive pressure key according to an embodiment of the present application, and as shown in fig. 5A, the principle of the piezoresistive pressure key is that a casing 51 on a middle frame of an electronic device is subjected to a force to generate a micro-deformation, so as to drive a pressure sensing module 52 in a pressure sensing sensor to generate a micro-deformation on a pressure sensing glue 53 in a steel sheet suspended area, so as to cause a change in resistance (i.e., R1, R2, R3, and R4 in the figure) in the pressure sensing glue 53, and perform detection through a wheatstone bridge. The plurality of resistance channels realize a key function, and the error touch prevention is realized through characteristic quantity information of the channels. The pressure button of display screen TP principle formula utilizes display screen TP principle, and electric capacity realizes the touch-control function promptly, realizes preventing the mistake through the double click operation and touches. Ultrasonic wave combines piezoresistive pressure button and combines through supersound and pressure drag, can use the supersound to realize position detection, and pressure drag realizes pressure detection to realize preventing the mistake and touching.
When a user uses the touch screen, the pressure sensor can convert the tiny deformation of the frame into a recognizable voltage signal by touching the frame, and the system can recognize the touch operation of the user by collecting and processing the signal. Meanwhile, the pressure key can also realize real key experience by matching with motor vibration feedback. Compared with a mechanical key, the pressure key can output a linear pressure value, and can realize multi-stage pressure operation such as light/medium/heavy operation and various operations such as single click, double click, sliding and the like.
Based on the foregoing embodiment, an embodiment of the present application further provides a method for switching a display screen, where the method includes monitoring whether an electronic device needs to switch horizontal and vertical screens by using a gravity sensor (an acceleration sensor is combined with a gyroscope), and then performing auxiliary judgment by using a side pressure button, so as to improve accuracy of switching the horizontal and vertical screens.
Firstly, the gyroscope and the accelerometer are used for normally detecting data such as X-axis linear acceleration, Y-axis linear acceleration and Z-axis linear acceleration of the acceleration sensor and three-axis angular acceleration of the gyroscope in different states such as holding and overturning of the electronic equipment, and identifying the angle of the electronic equipment according to the data such as the linear acceleration and the angular acceleration of the three axes. Wherein the acceleration sensor measures linear acceleration in the three-axis direction, and the gyroscope measures angular acceleration in the three-axis direction. Gyroscopes and acceleration sensors are commonly used sensors in intelligent electronic devices. The accelerometer detects an angle of inclination of the electronic device, and the gyroscope detects a change in angular acceleration, so that spatial states of the electronic device, such as inclination and rotation, can be detected in real time.
Fig. 5B is a schematic diagram of output values of acceleration and angle of the electronic device in the embodiment of the present application, where as shown in fig. 5B, a picture 501 is an output value of an X-axis acceleration, a Y-axis acceleration, a Z-axis acceleration, and an angle of the electronic device when the electronic device is a landscape screen. The picture 502 is an output value of an X-axis acceleration, a Y-axis acceleration, a Z-axis acceleration, and an angle of the electronic device when the electronic device is a vertical screen.
Secondly, the pressure keys on the side edges are used for judging whether the electronic equipment is in a horizontal screen state or a vertical screen state at the moment, so that the posture detection of the electronic equipment is assisted.
According to the method, the pressure key is used, the pressure sensing module is assembled at the position of the corresponding structure of the power supply/volume key of the middle frame of the electronic equipment through the pressure key in the embodiment of the application, and the pressure sensing film is slightly deformed at the position of the suspended area between the reinforcements after the shell of the middle frame of the electronic equipment is stressed, so that the resistance is changed to realize the pressure touch function. Pressing the key region, structural deformation is converted into voltage variation through the pressure sensing module, and the chip measures and judges whether the pressing is true and intended through algorithm logic. If the pressing is the real intention, an Input/Output (I/O) port is operated, the I/O port replaces a mechanical key power supply key in situ to be connected with an AP (Application Processor) end, and the pressing function is realized through level change. And the real key experience can be realized by matching with the motor vibration feedback.
Fig. 5C is a schematic diagram of a position of a side pressure key according to an embodiment of the present application, and as shown in fig. 5C, a pressure key 512 in an electronic device 511 may be located at a side of the electronic device (a power key and a volume key also belong to the side pressure key). The pressure button 513 in the electronic device 511 is an enlarged effect of the pressure button 512, that is, the pressure button 512 and the pressure button 513 are the same button. It can be seen that the pressure button 513 further includes a plurality of pressure sensing modules 514.
In the embodiment of the application, the electronic device held by the user can be divided into the following three modes:
(1) both hands hold the electronic equipment: fig. 5D is a schematic diagram of the electronic device held by two hands according to the embodiment of the present disclosure, as shown in fig. 5D, when the user holds the electronic device 52 by two hands 51 to perform a game operation or a video tour, the left and right fingers are respectively placed in the sensing areas of the side pressure keys, and a plurality of areas (i.e., channels) of the pressure keys of the electronic device are pressed. The structural deformation of the multiple areas is converted into voltage variation through the pressure sensing module, and a built-in chip of the electronic equipment measures the voltage variation and judges whether the pressing is true and intended through algorithm logic. If the pressing is the pressing with real intention, the I/O port is operated. By detecting information such as the size of the pressing area, the strength of the pressing force, the duration of the pressing and the like, it is determined that the electronic device is in the state of the horizontal screen, and in a preset time range, even if the calculated angle in fig. 5B is larger than a preset angle, the vertical screen operation is not performed temporarily.
(2) Holding the electronic device with one hand (vertical screen): namely, the single-hand vertical screen operation. Fig. 5E is a first schematic view illustrating the electronic device held by one hand according to the embodiment of the present disclosure, as shown in fig. 5E, when the user uses one hand 51 to erect the screen to operate the electronic device 52, the middle lower portion of the middle frame, the rear cover of the battery, and other areas will be held by the hand. The structural deformation of the middle and lower parts (the induction channels of the middle and lower parts are asymmetric) is converted into voltage variation through the pressure sensing module. By detecting information such as the size of the pressing area, the strength of the pressing force, the duration of the pressing and the like, it is determined that the electronic device is in the vertical screen state at the time, and in a preset time range, even if the calculated angle in fig. 5B is larger than a preset angle, the horizontal screen operation is not performed temporarily.
(3) Holding the electronic device with one hand (horizontal screen): i.e. single-handed landscape operation. Fig. 5F is a schematic view illustrating a single-hand-held electronic device according to a second embodiment of the present disclosure, as shown in fig. 5F, when a user uses a single hand 51 to hold an electronic device 52 in a landscape mode, according to a personal use condition, middle areas of left and right middle frames are pressed, corresponding pressure sensing areas are substantially symmetrical, and by detecting information such as a size of the pressed area, a strength of the pressing force, and a duration of the pressing, it is determined that the electronic device is in a landscape mode, and in a preset time range, even if the calculated angle in fig. 5B is greater than a preset angle, the user does not perform a portrait mode.
Of course, the embodiment of the application eliminates the interference of factors such as distorted false touch and middle frame false touch by a large amount of machine learning and model training and by defining parameters and models in different scenes (such as games, videos, reading, navigation and the like). For example, when the electronic device traverses a video tour scene, the semaphore of the first channel corresponding to the pressure button, the noise standard deviation of the first channel, and the bottom noise of the first channel are all greater than a certain threshold value within a continuous time period, and it is determined that the electronic device is in a stable horizontal screen stage at this time, and no vertical screen operation is performed for the time. The rest scenes can also be simulated by big data to obtain the desired parameter setting.
In the embodiment of the application, on the basis that two unification sensors (acceleration sensor combines the gyroscope) detect the electronic equipment gesture, combine the pressure button to carry out the scheme that supplementary gesture detected, can solve the unusual pain point problem of horizontal vertical screen of electronic equipment to a certain extent. And on the basis of the same electronic equipment model with the pressure keys and the two-in-one sensor, multi-module combined development is carried out, user experience is further optimized, and the technical effect of adding additional value on the basis of not increasing hardware cost is achieved.
The holding states of the transverse and vertical screens of the electronic equipment of different types are different, the sensing areas where the pressure keys of different scenes can be pressed can be defined according to the actual use condition of an individual, and the state that the electronic equipment is in the transverse screen or the vertical screen at the moment is judged by detecting the size of the pressing areas, the strength of the pressing force, the duration of the pressing and other information. And further increasing logic judgment of software, namely that the electronic equipment is used for horizontal/vertical screen at the moment, and in a preset time range, even if the angle is larger than the preset angle, vertical/horizontal screen operation is not performed temporarily.
In the switching method of the display screen in the embodiment of the application, the pressure keys on the side are used for assisting the gravity sensor (namely, the acceleration sensor is combined with the gyroscope) so as to optimize the automatic rotation function of the screen of the electronic equipment. The acceleration and the angle value of the electronic equipment can be obtained by utilizing the existing gravity sensor, so that whether the electronic equipment is in a horizontal screen or vertical screen state or not is judged. Meanwhile, the posture of the electronic equipment is judged in an auxiliary mode through the sensing area of the pressure key pressed by the user within a certain time, the intensity of the pressing force and the pressing time. Under the condition of ensuring the normal function of the original pressure key, the interference of factors such as distortion error touch, middle frame error touch and the like needs to be eliminated, and because the factors can cause the pressure sensing film at the position of the suspension area between reinforcements to generate micro deformation, the resistance is changed. When a signal is amplified by an ADC (Analog to Digital Converter), noise also causes an abnormality in function, and thus, is important for an application with a higher requirement for accuracy, such as a false touch prevention and interference prevention design.
