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 invention.
The term "and/or" herein is merely an association describing an associated object, meaning that three relationships may exist, e.g., a and/or B, may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.
The first embodiment is as follows:
an embodiment of the present application provides an electronic device, please refer to fig. 1, including:
a first processing unit 10, a display path 20 and a switching unit 30.
Specifically, the passageway 20 is shown to include two ends, a first port 201 and a second port 202. The first port 201 is connected to the first processing unit 10, or the second port 202 is connected to the first processing unit 10, which is not limited in this application. In the following description, it is assumed that the first port 201 is connected to the first processing unit 10.
The first processing unit 10 in the embodiment of the present application includes a plurality of sub-units. The plurality of sub-units include, but are not limited to, a sub-unit for generating and processing display content, a sub-unit for controlling a sensor of the electronic device to perform acquisition, a sub-unit for controlling the switching unit 30 to perform switching, a sub-unit for configuration, and the like.
The switching unit 30 comprises an input interface 301, a first output interface 302 and a second output interface 303. The input interface 301 is connected to either one of the first output interface 302 or the second output interface 303, thereby forming a path between the input interface 301 and the first output interface 302, or a path between the input interface 301 and the second output interface 303.
The second port 202 of the display path 20 is connected to the input interface 301. Meanwhile, the first port 201 of the display path 20 is connected to the first processing unit 10, and the input interface 301 is connected to the first output interface 302 or the second output interface 303, thereby forming a path from the first processing unit 10 to the first output interface 302, or a path from the first processing unit 10 to the second output interface 303.
Further, the first output interface 302 is also connected to the first display unit 40. Specifically, the first display unit 40 may be a built-in display unit of the electronic device, that is, the first display unit 40 is integrated with the electronic device and connected through at least one interface. For example, the electronic device is a mobile phone, and the first display unit 40 is a display screen of the mobile phone. Or the electronic device is a notebook computer, the first display unit 40 is a display unit of the notebook computer, and the like. Of course, in a specific implementation process, the electronic device may also be other devices including a built-in display unit, such as a smart watch, a palm computer, and the like, which is not limited in this application. In addition, the first display unit 40 may also be an external display unit, that is, the first display unit 40 and the electronic device are independent and not integrated. For example, the electronic device is a notebook computer, and the first display unit 40 is a television. In a specific implementation process, the first display unit 40 is an internal display unit or an external display unit of the electronic device, and a person having ordinary skill in the art can select the display unit according to the actual situation, which is not specifically limited in the present application.
In addition, the second output interface 303 is connected to the second display unit 50, and the first display unit 40 and the second display unit 50 are two different display units. Similar to the first display unit 40, the second display unit 50 may be an internal display unit or an external display unit, and the present application is not particularly limited.
In the embodiment of the present application, the first display content and the second display content may be the same or different. When the first display content and the second display content are the same, the technical solution in the embodiment of the present application may cause the same display content to be displayed on one of the first display unit 40 and the second display unit 50. When the first display content and the second display content are different, in order to obtain a better display effect, the electronic device may further display a display content with a higher display requirement on a better display unit. For example, the two display contents are a movie and a segment of text, respectively, and the display requirement of the movie is high. Assume that the resolution of the first display unit 40 is 1600 × 1200 and the resolution of the second display unit 50 is 640 × 480. The first processing unit 10 sends the movie as first display content to the first display unit 40 and the text as second display content to the second display unit 50.
Further, in the embodiment of the present application, the switching unit 30 may further include a plurality of remaining output interfaces, such as 4 output interfaces, 6 output interfaces, and the like, in addition to the first output interface 302 and the second output interface 303. Further, the display path 20 in the embodiment of the present application may connect a plurality of display units. The specific number of output interfaces and display units is not specifically limited in this application.
Since the switching manner and the specific deployment manner of the switching unit 30 are similar when the switching unit 30 includes three or more output interfaces, the following description will be given by taking an example in which the switching unit 30 includes two output interfaces and connects two display units.
In the embodiment of the present application, the switching unit 30 switches the input interface 301 between the first output interface 302 and the second output interface 303 according to a switching control signal. The switching control signal received by the switching unit 30 is from the first processing unit 10. The first processing unit 10 may send a switching control signal to the switching unit 30 through the display path 20. The first processing unit 10 and the switching unit 30 may be connected through a data Interface other than the display path 20, such as an SPI (Serial Peripheral Interface), a USB (Universal Serial Bus), or an I2C (two-row Serial Bus), and the first processing unit 10 may send a switching control signal to the switching unit 30 through the data Interface.
The switching unit 30 receives the switching control signal and switches according to the switching control signal. Specifically, when the switching control signal indicates that the first display unit 40 is required to display, the switching unit 30 does not need to switch if the input interface 301 is currently connected to the first output interface 302; when the input interface 301 is currently connected to the second output interface 303, the switching unit 30 switches the input interface 301 to be connected to the first output interface 302.
Similarly, when the switching control signal indicates that the second display unit 50 is required to display, if the input interface 301 is currently connected with the second output interface 303, the switching unit 30 does not need to switch; when the input interface 301 is currently connected to the first output interface 302, the switching unit 30 switches the input interface 301 to be connected to the second output interface 303.
The control information may be information generated by the first processing unit 10 according to a selection operation performed by a user on the human-computer interaction interface, or may be control information generated by the first processing unit 10 according to a switching cycle to periodically switch the display unit.
When the input interface 301 is connected to the first output interface 302, the first display unit 40 may receive the first display content transmitted by the first processing unit 10 through the display path 20 and display the first display content on the first display unit 40. When the input interface 301 is connected to the second output interface 303, the second display unit 50 may receive the second display content transmitted by the first processing unit 10 through the display path 20 and display the second display content on the second display unit 50.
Further, as shown in fig. 2, the electronic device in the embodiment of the present application further includes a fixing body 60 and a body 70. The first processing unit 10 and the switching unit 30 are disposed on the fixing body 60 and/or the main body 70.
When the electronic device is in the fixed state, the fixing body 60 maintains the relative position relationship between the electronic device and at least a part of the body of the user. In the implementation, the property parameter of the fixing body 60 is matched with the physical parameter of the user, for example, the electronic device needs to be fixed on the wrist of the user, and the effective circumference of the fixing body 60 around the wrist while maintaining the relative position relationship is greater than or equal to the circumference of the wrist. If the wrist circumference is typically between 13-17cm, then the effective circumference of the fixation body 60 should be at least 17 cm. Or for example, the electronic device needs to be fixed on the head of the user, and the length of one circle at the forehead of an adult is 54-58cm, so the circumference of the fixing body 60 can be 58cm, 59cm and the like.
For another example, the wrist of the human body is similar to an ellipse, and the distance from the palm to the back of the hand is smaller than the distance from the thumb to the little finger, so that the shape of the fixing body 60 can be set to an ellipse or a similar ellipse in order to make the fixing body 60 fit the wrist more, and the major axis and the minor axis are set according to ergonomic parameters. The person of ordinary skill in the art to which the present application belongs can set the setting according to actual needs, and the present application is not particularly limited.
The fixing body 60 and the body 70 in the embodiment of the present application may be directly connected by means of embedding, integral molding, or the like. Optionally, the electronic device in the embodiment of the present application further includes a connecting device, through which the body 70 is connected with the fixing body 60.
There are various implementations of the fixing body, two of which are listed below, and in the specific implementation, the following two are included but not limited.
The first method comprises the following steps: the fixing body at least has a fixing state, and can be used as at least one part of an annular space or at least one part of an approximate annular space meeting a first preset condition; wherein, the annular space or the approximate annular space can surround the periphery of the cylindrical body meeting the second preset condition.
Specifically, when the fixing body 60 includes only a portion, the fixing body 60 itself can form an annular space, as shown in fig. 2 and 3 a. If the fixing body 60 is made of a light elastic material, the fixing body 60 has a fixed state and an unfixed state; if the material of the fixing body 60 is a hard material, the fixing body 60 is only in a fixed state.
When the fixing body 60 includes two parts, a first end of the first part is connected to the first side of the body 70, and a third end of the second part is connected to the second side of the body 70, as shown in fig. 3 b. Further, if the material of the fixing body 60 is a hard material, and the second end of the first portion and the fourth end of the second portion are in a non-connected state, the fixing body 60 has only a fixed state, and the first portion and the second portion are two portions of an approximate annular space. The approximate annular space meets a first preset condition, namely the caliber between the second end of the first part and the fourth end of the second part is smaller than the caliber of a body part where the electronic equipment is worn, such as the caliber of a wrist, and the wrist is regarded as a cylindrical body at the moment. The cylindrical body satisfies a second predetermined condition, i.e. greater than the aperture of the annular space, and further, if the electronic device is to be relatively fixed at a certain position or a certain height of the cylindrical body, the diameters of the two ends of the cylindrical body should be smaller than the diameter of the annular space.
Alternatively, the second end of the first portion and the fourth end of the second portion may be provided with a coupling structure, such as a pin buckle, a folding safety buckle, or a butterfly buckle. When the second end and the fourth end are connected, the two parts together form an annular space, the fixing body 60 is in a fixed state, and when the second end and the fourth end are in a non-connected state, the fixing body 60 is in a non-fixed state.
And the second method comprises the following steps: the fixing body is at least in a specific fixing state; the fixed body can be used as at least one part of an annular space or at least one part of an approximate annular space meeting a first preset condition; wherein the annular space or the approximate annular space can surround a near-spherical periphery satisfying a third preset condition.
The second implementation is the same as the first implementation and is not described here. The second implementation is different from the first implementation in that, as shown in fig. 3c, the electronic device is worn on a part of the user's body, such as the head, and the head is regarded as a near-spherical body. The near-spherical body meets a third preset condition, namely the caliber of the near-spherical body is larger than that of the annular or approximate annular space.
As can be seen from the above description, in the implementation process, the electronic device in the present application may be embodied as a wrist strap type electronic device, and therefore, the size is small, so that the number of display channels in the electronic device is limited. Therefore, when the electronic equipment needs a plurality of display units for displaying, the number of the display units can be increased under the condition of limited display paths by using the technical scheme in the embodiment of the application.
Further, the first display unit 40 and/or the second display unit 50 in the embodiment of the present application are built-in display units of the electronic device.
In the embodiment of the present application, the display principle of the first display unit 40 and the second display unit 50 is different. Specifically, the first display unit 40 and the second display unit 50 may be any two different display units among a Liquid Crystal Display (LCD) unit, a Light Emitting Diode (LED) unit, an organic Light-Emitting Diode (OLED) unit, or an electronic Ink (Elctronic Ink) display unit, and thus display principles of the two display units are different. For example, the first display unit 40 may be an LED display unit and the second display unit 50 may be an OLED display unit.
Further, in the embodiment of the present application, the first display unit 40 is specifically a display unit displaying a real content image in any one of an LCD, an LED, an OLED, or an EINK. And the second display unit 50 is embodied as a display unit that can display a virtual image that is accommodated within the second display.
Specifically, the first optical member in the first display unit 40 emits light according to the first display content. The emitted light then reaches a first display element in the first display unit 40, which is activated to display a real image of the first display content. Since the principle of displaying the real image of the first display content by the first display unit 40 is known to those skilled in the art to which the present application pertains, the detailed description thereof is omitted here.
Further, the second display unit 50 has a structure as shown in fig. 4, including:
a second display module and a second optical module;
the second display module is used for displaying the second display content; the second optical module is used for receiving light rays which are sent by the second display module and correspond to the second display content, and carrying out light path conversion on the light rays corresponding to the second display content to form an amplified virtual image corresponding to the second display content.
Specifically, the second display unit 50 is disposed on the fixing body 60 and/or the body 70. The second display unit 50 includes two modules, a second display module 401 and a second optical module 402. First, the second display module 401 includes a second light emitting element, and the second light emitting element emits light according to a second display content. The emitted light penetrates through the beam splitting assembly to reach the second display assembly, and the second display assembly is excited to display second display content.
The beam splitting assembly comprises two surfaces, and the transmissivity of the first surface facing the second optical assembly is higher than the reflectivity, so that light rays emitted by the second optical assembly can penetrate through the beam splitting assembly to reach the second display assembly. And the reflectivity of the second side facing the second display assembly is higher than the transmissivity, so that the reflected light reflected from the second display assembly can enter the second optical module 402 after being reflected by the second side.
The second optical module 402 receives light corresponding to the second display content from the second display module 401, and performs optical path conversion in the collimating assembly. The convex lens and the concave lens in the collimating unit can magnify the light and change the direction of the light so that the magnified light can be incident into the reflecting assembly.
The amplified light is incident on the reflection assembly. According to the physical principle of mirror surface imaging, after the amplified light rays are emitted into the reflection assembly, due to the mirror surface principle, an amplified virtual image of the second display content is formed. Finally, light rays emitted by the enlarged virtual image are incident on the eyes of the user, so that the user sees the enlarged virtual image of the second display content.
As can be seen from the above description, since the electronic device in the embodiment of the present application may be a wearable electronic device, the display unit of the wearable electronic device is generally small, but the user also wants to see a large screen on the wearable electronic device. The second display unit in the embodiment of the present application thus satisfies the user's demand by displaying an enlarged virtual image of the second display content. Further, the first display means still displays the real image of the first display content so that the user can see the display content with high resolution and clear image quality. In other words, the two display units with different display principles in the embodiment of the application can meet the requirement of a user for watching a large picture, and simultaneously avoid poor visual experience of the user.
When the switching unit 30 switches the display of the two display units, the display unit that is displayed after switching needs to receive the display content and perform normal display after initialization operation, and the display unit that is displayed before switching may stop displaying at the time of switching, so that the user may visually appear that the two display units are simultaneously blank. Alternatively, when the display areas of the two display units are close, even if the initialization time is short, the situation of simultaneously blacking the screen does not occur visually to the user. However, since the two display units switch the display instantaneously, the user still feels a bad experience of instantaneous jump or flicker. To avoid the above two situations, optionally, in this embodiment of the application, taking the first display unit before switching as an example, the first processing unit 10 is further configured to:
when the switched unit 30 switches the input interface 301 to be connected with the second output interface 303, the first display unit 40 is controlled to be in the second mode.
Specifically, assuming that the switching unit 30 switches the input interface 301 to be connected with the first output interface 302, the first display unit 40 receives and displays the first display content transmitted by the first processing unit 10. Therefore, the display unit before switching is the first display unit 40. In order to avoid the above two situations of poor user experience, the first processing unit 10 controls the first display unit 40 to be in the second mode after the input interface 301 is switched to the second output interface 303 for connection.
The first processing unit 10 may send the first control information to the switching unit 30 through the display path 20. The switching unit 30 then transmits the first control information to the first display unit 40. Of course, the first processor 10 may also send the first control information to the switching unit 30 through other interfaces, such as SPI, USB, and the like, and the application is not limited thereto.
In the embodiment of the present application, the first control information is used to control the first display unit 40 to operate in the first mode. The first mode is a mode in which the first display unit 40 receives the first display content and is continuously displaying the first display content. In other words, after receiving the first display content, the first display unit 40 displays each frame of image of the currently received first display content. The first display unit 40 displays the next frame image immediately after the current frame is displayed. The first menu 40 will continue to be displayed as long as the first display content continues to be received. And if the next frame is not received after the current frame is displayed, stopping displaying.
And the second mode is a mode in which the first display unit 40 is continuously in a display state after not receiving the first display content.
In order to realize that the first display unit 40 is continuously in the display state after not receiving the first display content, in the implementation of the present application, the second mode may specifically be: the first display unit 40 continues to display a single frame image after not receiving the first display content. In addition, the single frame image continuously displayed may be a preset image of one frame, which is buffered in the first display unit 40 in advance. When the first display unit 40 operates in the second mode, the first display unit 40 reads and displays a preset image. In a specific implementation process, the preset image may be a landscape image, a person image, or the like. Alternatively, in order to prompt the user that the first display unit 40 and the second display unit 50 are switching the display, the preset image may also be an image including suggestive characters such as "switch in progress", "please wait for switch", and the like. This application ordinary technical personnel in the field can be with the actual choice preset the image, and this application does not do specific limitation.
Preferably, the single frame image continuously displayed is any one frame in the first display content. And to avoid display skipping while operating in the second mode, the single frame image is preferably selected as the last frame image of the first display content.
In the implementation of the present application, the second mode may further specifically be: the first display unit 40 continuously switches the mode of displaying the plurality of frames of images after not receiving the first display content.
Specifically, the first display unit 40 further includes a first processor for switching a plurality of frames of images. The power consumption of the first processor is less than that of the first processing unit 10, so that the first display unit 40 can maintain display without consuming a large power consumption. The first processor switches the plurality of frames of images at a switching speed of not less than 30fps, which causes the user to finally see the video in the display area of the first display unit 40. Of course, in a specific implementation process, the switching speed may be less than 30fps, so that the user can see the switching of multiple still images, and the application is not limited in particular.
In a specific implementation process, the multi-frame image may also be a preset image pre-stored in the first display unit 40, for example, a 300-frame image of an animation with a duration of 10 seconds. When the first display unit 40 operates in the second mode, the 300 frames of images are continuously switched and displayed, so that the user can see that the same animation film for 10 seconds is played on the first display unit 40 at least once. Of course, the multi-frame image may also be a multi-frame image in the first display content. The general technical personnel in this application field can set up according to the reality, and this application does not do the specific limitation.
Of course, the second display unit 50 may include the above two modes. And the two modes included in the second display unit 50 are similar to the two modes of the first display unit 40, and are not described in detail here.
In the embodiment of the present application, the first processing unit 10 sends a switching control signal to the switching unit 30 to trigger the switching unit 30 to switch. The switching control signal may be generated according to a selection of a user on the human-computer interaction interface, or may be periodically generated by the first processing unit 10, for example, the switching control signal is generated every 10 minutes to switch the display unit once by the switching unit 30, or may be generated by the first processing unit 10 according to a trigger of the user. The present application is not particularly limited.
In particular, the switching control signal is generated by the first processing unit 10 upon user activation, and in this embodiment of the application, the electronic device further comprises a first sensor for obtaining the first parameter. The first processing unit 10 is specifically configured to:
before controlling the first display unit to be in the second mode, judging whether the first parameter meets a first preset condition; when the first parameter meets the first preset condition, it is determined that the switching unit needs to switch the input interface to be connected with the second output interface.
Specifically, the electronic device obtains the first parameter through the first sensor before switching to the display of the second display unit 50. When the first parameter meets the first preset condition, the first processing unit 10 determines that the switching unit 30 needs to be switched, and further generates a switching control signal to trigger the switching unit 30 to switch. The first sensor may be of various types, and there are various ways to obtain the first parameter and determine whether the first parameter satisfies the preset condition. Three of these will be listed below, and in particular implementations, the following three are included, but not limited.
The first method comprises the following steps: distance sensor
The sensor is a distance sensor disposed within a preset range of the second display region of the second display unit 50, and detects a distance between the viewer and the second display region. The second display area is an area where the second display unit 50 displays an enlarged virtual image, specifically, an exit area of the reflection assembly that displays light. Similarly, the first display area of the first display unit 40 is an area where the first display unit 40 displays a real image. The first parameter at this point is the distance between the viewer and the first display area.
The first preset condition is that the first parameter is smaller than a first threshold value. When the viewer views the second display region, the distance between the viewer and the second display region may be short, and then the first processing unit 10 switches the display of the second display unit 50 for the convenience of the viewer. The first threshold value may be a default setting of the electronic device, or may be a user-defined setting of the viewer. For example, if the first parameter is 20 cm, and the first threshold is 30 cm, the first parameter is smaller than the first threshold, and the first parameter satisfies the first predetermined condition. The first processing unit 10 thus determines that the switching unit 30 needs to switch the connection of the input interface 301 and the second output interface 303 to cause the second display unit 50 to display.
The first method comprises the following steps: image collector
The image collector collects gestures of a viewer, and the first parameter at the moment is an image parameter of the viewer.
The first preset condition is whether the gesture in the image meets preset gesture characteristics. Specifically, after the image of the viewer is captured, the first processing unit 10 performs feature analysis on the image to analyze whether the gesture in the image satisfies a preset gesture feature. For example, assuming that the preset gesture is a right hand sliding from left horizontal to right, the image is analyzed, and when the viewer gesture satisfies the characteristic that the right hand slides from left horizontal to right, it is determined that the viewer gesture satisfies the preset gesture, so that the first parameter satisfies the preset condition. The first processing unit 10 thus determines that the switching unit 30 needs to switch the connection of the input interface 301 and the second output interface 303 to cause the second display unit 50 to display.
And the third is that: push-button or switch
When the sensor is embodied as a button or a switch, and the pressure sensor is connected to the button or the switch, the first parameter is embodied as an on-off parameter of the button or the switch. The first preset condition is that the button or switch is on.
For example, when the user needs to switch to the second display unit 50 for displaying, the user presses the button, the pressure sensor detects the pressure, and the first parameter is sent to the first processing unit 10 as the button is turned on. The first processing unit 10 determines that the first parameter satisfies a first preset condition. The first processing unit 10 thus determines that the switching unit 30 needs to switch the connection of the input interface 301 and the second output interface 303 to cause the second display unit 50 to display.
Further, in order to reduce the burden of the apparatus, after the second display unit 50 starts displaying, when the first display unit 40 satisfies a second preset condition, the first display unit 40 is controlled to be in a third mode in a non-connection state with the display path 20;
the third mode is a mode in which the first display unit 40 is in a non-display state.
Specifically, the third mode is a mode in which the first display unit 40 is in a non-display state, such as a black screen, a sleep mode, or the like. In a specific implementation process, in order to further reduce the power consumption of the first display unit 40, after the first display unit is in the third mode, the power supply of the first display unit 40 is switched.
In the embodiment of the present application, two ways are available for determining whether the first display unit 40 satisfies the second preset condition.
(1) The first processing unit 10 is configured to: it is determined whether the time period of the first display unit 40 in the non-connected state with the display path 20 exceeds a preset time period.
Specifically, after the switching unit 30 switches, the first processing unit 10 starts counting time. And when the timing reaches the preset time length, sending second control information to the first display unit 40. Wherein the second control information is transmitted through a data interface between the first processing unit 10 and the first display unit 40. And, in the specific implementation process, the preset time period should be longer than the time from the switching unit 30 to the normal display of the second display unit 50. For example, the initialization time after the second display unit 50 is switched is 20 milliseconds, 5 milliseconds are required for the display content to be transmitted from the first processing unit 10 to the second display unit 50, and 15 milliseconds are required for the second display unit 50 to read and display the display content. Therefore, the preset duration should be greater than 40 milliseconds, such as 1 s.
(2) A second sensor of the electronic device is configured to obtain a second parameter, and the first processing unit 10 is configured to: and judging whether the second parameter meets the second preset condition.
Specifically, in the embodiment of the present application, the second sensor and the first sensor may be the same or different. There are various ways to obtain the second parameter and determine whether the second parameter satisfies the second preset condition. Three of these will be listed below, and in particular implementations, the following three are included, but not limited.
The first method comprises the following steps: distance sensor
The second sensor is the same distance sensor as the first parameter was acquired, then the second parameter at this time is also the distance between the viewer and the second display area.
The second preset condition is that the second parameter is smaller than a second threshold value, and the second threshold value is smaller than the first threshold value. The second threshold may be an optimal distance or an optimal angle for viewing the second display region, or may be set by the viewer. For example, if the second parameter is 20 cm, and the second threshold is 25 cm, the second parameter is smaller than the second threshold, and the second parameter satisfies the second predetermined condition. So that the first processing unit 10 controls the first display unit 40 to stop in the first mode.
As is apparent from the above description, since the second display unit 50 in the embodiment of the present application displays an enlarged virtual image, a different effect is observed depending on the distance or angle of the observer from the second display region when viewing the enlarged virtual image. Therefore, in the embodiment of the present application, when the user moves from viewing the first display region to a distance at which the user can view the second display region, the first processing unit 10 automatically switches to the second display unit 50 for display. When the first parameter is smaller than the first threshold and larger than the second threshold (specifically, the second threshold is the optimal distance for viewing the second display region), the user cannot preferably view the second display region, so that the first display unit 40 is controlled to continuously display, thereby preventing the user from visually displaying a black screen of two display units. When the user moves to the optimal viewing position, that is, the second parameter is smaller than the second threshold, the first processing unit 10 controls the first display unit 40 to be in the third mode, so that the user can be provided with better experience, and the first display unit 40 can be prevented from consuming electric energy.
The first method comprises the following steps: image collector
The second sensor and the first sensor are the same image collector, and then the second parameter at this time is the image parameter of the viewer.
The second preset condition is whether the gesture in the image meets a second preset gesture characteristic. For example, assuming that the second preset gesture is a vertical sliding downward of the right hand from the top, the image is analyzed, and when the viewer gesture satisfies the feature that the right hand slides downward from the top, it is determined that the viewer gesture satisfies the second preset gesture, so that the second parameter satisfies the second preset condition. So that the first processing unit 10 controls the first display unit 40 to be in the third mode.
And the third is that: touch control display screen
When the first sensor is a button or a switch and the second sensor is a touch display screen, the second parameter is a touch position parameter of the operating body on the touch display screen. The second preset condition is that the position parameter is within the range of the second display unit 50, that is, when the operating body touches the touch display screen on the second display unit 50, the first processing unit 10 sends second control information to the first display unit 40, so that the first display unit 40 is in the third mode.
Example two:

s101: the switching unit of the electronic device switches the connection between the input interface of the switching unit and the second output interface of the switching unit to the connection between the input interface and the first output interface of the switching unit, or the switching unit switches the connection between the input interface and the first output interface to the connection between the input interface and the second output interface.

obtaining, by a first sensor of an electronic device, a first parameter;
judging whether the first parameter meets a first preset condition or not;
when the first parameter meets the first preset condition, it is determined that the switching unit needs to switch the input interface to be connected with the second output interface.

when the first display unit meets the second preset condition, controlling the first display unit to be in a third mode under the condition that the first display unit is not connected with the display path; wherein the third mode is a mode in which the first display unit is in a non-display state.
Specifically, determining whether the first display unit meets a second preset condition includes:
and judging whether the duration of the first display unit in a non-connection state with the display passage exceeds a preset duration.
Or, judging whether the first display unit meets a second preset condition, specifically including:
obtaining a second parameter by a second sensor;
and judging whether the second parameter meets the second preset condition.

Therefore, the connection of the first display unit and the second display unit with the display channel is switched by switching the connection relationship between the input interface and the first output interface and the second output interface through the switching unit, so that the display channel in the embodiment of the application can not be connected with only one display unit any more, the technical problem that the number of the display units is limited by the number of the display channels in the prior art is solved, and the technical effect that one display channel is connected with at least two display units is realized.
