Detailed Description
The present application is described in further detail below in conjunction with figures 1-2.
The embodiment of the application discloses a mobile phone with double-sided operable.
Referring to fig. 1, a mobile phone with two operable sides comprises a casing 1, a main board and a touch display screen, wherein the main board is internally installed in the casing 1; the touch display screens are two, are connected to the main board by electric signals and are respectively embedded and arranged at the front part and the rear part of the shell 1.
Regarding the front touch display, it is configured to: the touch control system is used for executing the normal function of realizing the touch control mobile phone, namely displaying UI interaction information and sensing a touch control action output signal of the user mobile phone to the main board.
Regarding the rear touch display screen, it is configured to: the soft keyboard is used for orthographic projecting and displaying a soft keyboard displayed by a touch display screen at the front part, and sensing touch actions of fingers of a user to output signals to the main board.
Specifically, the motherboard is configured to: the device is used for synchronously controlling the touch display screen at the rear part to display the soft keyboard when the touch display screen at the front part displays the soft keyboard;
at this time, the displayed result of the back soft keyboard is not a normal soft keyboard display with the back surface as the front surface of the mobile phone, but is that: the front touch display screen is projected on the back to obtain a soft keyboard, namely, the front key Q is close to the left side of the mobile phone, then the case Q on the back is close to the same side of the mobile phone, or can be called a mirror image keyboard, but not compliant with the visual angle, and the case Q on the back is close to the other side of the mobile phone.
According to the arrangement, when a user holds the mobile phone, especially when both hands are matched with the mobile phone, the user can operate the soft keyboard on the back of the mobile phone through 8 fingers (except thumb) arranged on the back of the mobile phone, and the user can be matched with typing, etc.; meanwhile, the back surface does not make other display under the situation, so that the soft keyboard on the back surface can be displayed in a larger size, and the operability is improved; meanwhile, because the display form of the back soft keyboard is adopted, a user can perform touch typing on cognition and memory of the soft keyboard in a conventional way, so that the operability is better and the error is less prone to occur.
In order to avoid abnormal starting of the back soft keyboard and influence the experience, the following settings are made: the UI interaction information also comprises a back enabling key, the function key is also realized on the UI interface in a soft mode, and the function key is used in cooperation with a soft keyboard in the UI interaction information.
At this time, the main board is configured to: and the touch control action of the touch control display screen at the back relative to the back is responded after the back starting key is triggered.
According to the above, the soft keyboard on the back is not always effective in touch, but only after the corresponding enabling key is touched on the touch display screen on the front by the user, the main board can respond to the touch display screen on the rear, so that misoperation and the like of the user can be avoided.
For some users, a certain difficulty exists in "touch typing" of the soft keyboard on the back, and for this purpose, the application is further set as follows:
the touch display screen is configured to: the touch control display screen is used for synchronously displaying the soft keyboard when the touch control display screen at the rear part displays the soft keyboard, and highlighting marks on the soft keyboard at the front part according to the touch control action of the fingers of a user relative to the soft keyboard at the rear part.
It can be understood that the soft keyboards are synchronously displayed by the two touch display screens, and meanwhile, the touch state of the back soft keyboard is displayed on the front soft keyboard in a highlighting mode, so that when a user operates the touch display device, touch typing is not actually performed, but the key condition of the back is synchronously displayed by the front soft keyboard in a highlighting mode, so that the operability is higher, and the misoperation probability is reduced.
Under the situation, the front soft keyboard is mainly used for facilitating the observation of users without actually touching the soft keyboard, so that the display area of the soft keyboard can be reduced, and more space is reserved for other display contents.
Because the palm size of each user is different, the operation habit is different, so in order to more convenient user to the soft keyboard operation on the back, the mainboard is still configured to: the device is used for responding to preset segmentation instructions and controlling the segmentation, combination and movement of the soft keyboard displayed on the rear display screen.
The dividing instruction includes an instruction corresponding to a signal triggered and output by a touch action, for example: drawing a cross on the back touch display screen, namely triggering dividing, combining and moving instructions, wherein at the moment, the dividing, combining and moving instructions can be marked along the edges of all keys, namely drawing an O to enclose the keys to be divided, and dragging the keys to realize movement; subsequently, a cross is drawn again to indicate that the segmentation is finished.
For the touch display screen on the back, if only a single soft keyboard is used for displaying, the waste is relatively high, and for this reason, the main board is further configured to: the touch control display screen is used for responding to a preset back display instruction and controlling the back touch control display screen or the two touch control display screens to simultaneously display the UI interaction information; the back display instruction comprises a single display instruction and a double-sided display instruction.
It will be appreciated that the single display instruction and the double-sided display instruction may be: the function keys displayed on the UI interface are realized through software, and the signals output after the function keys are triggered correspond to each other.
For the back soft keyboard of the application, there is a defect in operation, namely when the mobile phone is held by both hands, the back of the mobile phone directly falls on fingers, so that at least one static touch action exists on the touch display screen on the back all the time, more flexible programs for dynamic touch response and the like are required to be designed, and the situations are relieved and even avoided.
Referring to fig. 1 and 2, the present application makes the following settings: the back operation auxiliary device is used for being matched with the operation of the touch display screen at the rear part, and comprises a movable functional plate 2, a guard plate 3 and connecting ribs 4.
The two guard plates 3 are respectively located at the upper side and the lower side (top+bottom) of the casing, the end heads of the guard plates are bent along the side edge of the casing 1 and extend along the side edge of the casing 1 to form the connecting ribs 4, and the two guard plates 3 are connected through the connecting ribs 4 to form a 'mouth' structure.
The movable functional board 2 is hinged with the connecting ribs 4 (actually, the guard board 3) through a hinge shaft, the movable functional board 2 is arranged along the side part of the casing 1, and a plurality of stable finger grooves 21 for adapting fingers are formed in one side far away from the casing 1.
The two movable functional boards 2 are symmetrically arranged on two sides of the casing 1, and when the two movable functional boards 2 are attached to the touch display screen on the back, the unstable finger grooves 21 are partially close to each other so as to shield the touch display screen and play a role in protection when necessary. In order to improve the connection stability of the two movable functional boards 2, a middle connecting strip, such as a soft magnetic strip embedded, is arranged on one side of the movable functional board 2 away from the connecting ribs 4.
When the back display screen is required to be operated, the fingers are buckled into the stable finger grooves 21, the two movable functional plates 2 are turned over by about 180 degrees to be flattened, and then the middle sections of the fingers or the roots of the fingers are clamped in the stable finger grooves 21; at the moment, the movable functional board 2 is held by the finger, so that the mobile phone is held without directly applying force to the touch display screen; meanwhile, the finger can continue to perform touch operation on the touch display screen on the back surface.
In order to ensure the simultaneous operability of the fingers of the user on the two touch display screens, the movable functional board 2 is concavely matched with the palm in the holding state away from the side part of the casing 1, and the stable finger groove 21 is positioned in the concave area.
Considering the holding posture, the groove wall of the stabilizing finger groove 21 is set to be inclined, and the lower end thereof is inclined toward the side of the housing 1 (at the time of the flat posture).
In order to ensure the flattening effect, prevent excessive overturning, etc., a restoring member for driving the movable functional board 2 to rotate towards the rear touch display screen is configured for the movable functional board 2, and the restoring member may be a torsion spring which is mounted on the hinge shaft of the movable functional board 2.
It will be appreciated that the protection plate 3 is only used to form the connection ribs 4 to connect the movable functional board 2, which is relatively wasteful, for this further, the protection plate 3 and the connection ribs 4 are arranged to cover the side portion of the casing 1, and the protection plate 3 extends on the back surface of the casing 1 to form an area covering the non-touch display screen, and the camera area is also not covered.
According to the arrangement, the back operation auxiliary device is not only used for being matched with the operation of the soft keyboard on the back, but also can be used for protecting the touch display screen on the back to a certain extent.
The foregoing are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in any way, therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
