The invention discloses an electronic device with an extensible display and a control method therefor, by adding an auxiliary display on the other side of the mobile terminal, the front and back sides of the mobile terminal can be utilized for display simultaneously, which is suitable for multi-user scenarios, on the other hand, according to the different display contents of the mobile terminal, a specific display can be selected to obtain better display results.
In order to manifest the purposes, technical schemes and advantages of the present invention, the present invention is further detailed with drawings and embodiments in the following description. It should be understood that specific embodiments described herein is used only to explain the present invention and not intended to limit the present invention.
As shown in
Some specific embodiments are given in the following for detailed description of the technical scheme of the present invention.
As shown in
Further, the auxiliary display 40 is located on a surface of the first rear cover 22 of the protective sleeve 20 facing away from the front cover 21, and the auxiliary display 40 is electrically connected to the keyboard 30, thus realizing the communication between the auxiliary display 40 and the mobile terminal 10. The protective sleeve 20 also includes a second rear cover 24 in connection to the flexible part 23, and the second rear cover 24 is on an outer side of the first rear cover 22. When the protective sleeve 20 is closed, the second rear cover 24 covers the auxiliary display 40 for protection.
In other embodiments, a second thimble is disposed on the back of mobile terminal 10 to achieve an electrical connection between the auxiliary display 40 and the mobile terminal 10. A through hole is formed on a position on the first rear cover 22 corresponding to the second thimble. The second thimble is in an electrical connection with a corresponding interface on the auxiliary display 40 through the through hole.
Further, as shown in
As shown in
In step 51, detection is performed as to whether the mobile terminal 10 is in a communication state with the keyboard 30.
Specifically, a signal level on the communication port of the mobile terminal 10 is detected. When the signal level is high, the first thimble is electrically connected to the communication port, then the mobile terminal 10 is in a communicationally connected state with the keyboard 30. When the signal level is low, the first thimble is disconnected form the communication port, then the mobile terminal 10 is in a communicationally disconnected state with the keyboard 30.
In step 52, detection is performed as to whether the power switch 11 is in a triggered state, and determination is performed as to whether duration of the triggered state reaches a preset value. When the duration reaches the preset value, the auxiliary display 40 is selectively switched on or off according to the detected communication state of the mobile terminal 10 and the keyboard 30. For example, the preset value is set to 5 seconds.
Specifically, when the power switch 11 is selected as a key switch, detection is performed as to whether the power switch 11 is in a pressed state, and determination is performed as to whether duration of the pressed state reaches the preset value. When the duration reaches the preset value, the auxiliary display 40 is selectively switched on or off according to the detected communication state of the mobile terminal 10 and the keyboard 30. Alternatively, when the power switch 11 is selected as a touch switch, detection is performed as to whether the power switch 11 is in a pressed state, and determination is performed as to whether duration of the pressed state reaches the preset value. When the duration reaches the preset value, the auxiliary display 40 is selectively switched on or off according to the detected communication state of the mobile terminal 10 and the keyboard 30.
Specifically, as shown in
The electronic device of the embodiment is suitable for a multi-user scenario. For example, when a user needs to share display with others, rather than having to separate the mobile terminal 10 and the keyboard 30, the user triggers the power switch 11 for duration of the triggered state reaching the preset value, thus to transfer the screen of the main display to the auxiliary display 40 on the surface of the first rear cover.
As shown in
As shown in
The mobile terminal 10 is switched on, and detects the communication state between the mobile terminal 10 and the keyboard 30. When the two are in a communicationally disconnected state, a display mode of the mobile terminal is maintained. When the two are in a communicationally connected state, detection is performed as to whether duration for which the power switch 11 is in the triggered state reaches the preset value. When the preset value is not reached, a display mode of the mobile terminal is maintained. When the preset value is reached, the auxiliary display 40 on the back of the terminal 10 is switched on, and a screen of the main display is transferred to the auxiliary display 40.
A scenario of the communicationally disconnected state between the mobile terminal 10 and the keyboard 30 is to separate the mobile terminal 10 and the keyboard 30, and detach mobile terminal 10 from the protective sleeve 20. The auxiliary display 40 may be a display of electronic ink. An electronic ink display has real paper like display effect, which is more suitable for text reading. When reading text using the mobile terminal 10, a user can take the mobile terminal 10 out of the protective sleeve 20, then trigger the power switch 11 for duration of the triggered state reaching the preset value, thus to switch a screen of the main display to the auxiliary display 40, and may enable the forward page turning function, the backward page turning function, and the return function using other function keys on the side of the terminal 10.
Further, a window 22a is formed on the first rear cover 22 and arranged over the auxiliary display 40 to expose the entirety of the auxiliary display 40, so that the terminal 10 needs not to be detached from the protective sleeve 20 when a screen of the main display is transferred to the auxiliary display 40. Specifically, the protective sleeve 20 is closed, the communication port on the mobile terminal 10 is disconnected from the first thimble on the keyboard 30 while both of the mobile terminal 10 and the keyboard 30 are in the protective sleeve 20. When the power switch 11 is triggered for duration of the triggered state reaching the preset value, a screen of the main display screen is transferred to the auxiliary display 40. The mobile terminal 10 also has a sensor for detecting whether the mobile terminal 10 is closed in the protective sleeve 20. When the mobile terminal 10 is detected as being closed in the protective sleeve 20, the main display of the mobile terminal 10 is switched off.
The invention discloses an electronic device with an extensible display and a control method thereof, which may carry out synchronized display with the provision of an auxiliary display screen on the other side of the mobile terminal, and thus the electronic device is suitable for multi-user scenarios. Additionally, a specific display screen may be selected according to different display content of the mobile terminal so as to obtain a better display effect.
Even though the foregoing specific embodiments of the present disclosure are detailed in the above description, as is understood by persons skilled in the art, however, various modifications and improvements can be made unto the embodiments without departing from the principle and spirit of the present disclosure, and should be protected in the scope of the claimed invention.
