3 is a flow chart of a control method in accordance with an embodiment of the present invention. In step S305, the magnetic flux sensing result is obtained by the magnetic flux sensor 120. Since the magnet 240 is disposed in the first body 21 and the magnetic flux sensor 120 is disposed in the second body 22, when the first body 21 passes through the pivot structure 23 and the second body 22 relatively moves within the magnetic induction range The control unit 130 can obtain the first logic potential from the magnetic flux sensor 120. When the first body 21 and the second body 22 do not move relative to each other within the magnetic induction range, the control unit 130 may obtain the second logic potential from the magnetic flux sensor 120. Here, the first logic potential is, for example, "1", and the second logic potential is, for example, "0". The magnetic induction range is, for example, 5° to 14°, that is, when the angle of the first body 21 relative to the second body 22 is within 5° to 14°, the magnetic flux sensor 120 generates a first logic potential.

The magnetic flux sensor 120 is used to determine the opening and closing of the first body 21 relative to the second body 22, and the motion sensor 110 is used to detect the flip angle and direction of the first body 21, thereby accurately determining the portability. The operating state of the electronic device 20.

Specifically, when the magnetic flux sensing result is the first logic potential, the processing unit 140 further determines, according to the motion information, that the current operating state is a pop-up mode or a tablet mode. When the magnetic flux sensing result is the second logic potential, the processing unit 140 further determines, according to the motion information, that the current operating state is a viewing mode or a floating mode. The above four operating states are described below for further examples.

4A-4D are schematic diagrams of four operational states in accordance with an embodiment of the present invention. 4A represents a panning mode, FIG. 4B represents a tablet mode, FIG. 4C represents a floating mode, and FIG. 4D represents a viewing mode.

In FIG. 4A , the first body 21 is configured with one of the touch display panels 210 . The surface faces the side of the second body 22 where the touch panel 230 and the keyboard 230 are disposed. In the squat mode, the user wants to slap the first body 21 and the second body 22, so the control unit 130 disables the keyboard 230, the touch panel 220, and the touch display panel 210.

In FIG. 4B , the first body 21 is disposed with the touch display panel 210 facing upward, and the back surface of the first body 21 (the side where the touch display panel 210 is not disposed) is disposed toward the second body 22 . One side of the control board 220 and the keyboard 230. In the tablet mode, the user wants to use the portable electronic device 20 as if using a general tablet computer, that is, the user only wants to use the touch display panel 210. Therefore, the control unit 130 enables the touch display panel 210. Moreover, in order not to cause the keyboard 230 on the second body 22 to be accidentally touched, the control unit 130 also disables the keyboard 230. In addition, in the tablet mode, the control unit 130 can also disable the touch panel 220 at the same time.

In FIG. 4C , the first body 21 is suspended above the second body 22 through the pivot structure 23 . In the floating mode, the user is intended to use the touch display panel 210 and the keyboard 230. Therefore, the control unit 130 enables the keyboard 230 and the touch display panel 210 to disable the touch panel 220.

In FIG. 4D, the first body 21 passes through the pivot structure 23 and holds the upright posture with the second body 22 as a base. That is, one surface of the first body 21 on which the touch display panel 210 is not disposed faces one side of the second body 22 on which the touch panel 220 and the keyboard 230 are disposed. In the viewing mode, the user wants to use the touch display panel 210 to view a movie, video, and the like. Therefore, the control unit 130 enables the touch display panel 210 and disables the keyboard 230 and the touch panel 220.

Specifically, in this embodiment, the control unit 130 will be at intervals. The interrupt signal is sent to the processing unit 140, so that the processing unit 140 executes the related application (Application, AP) to read the current motion information of the motion sensor 110. When the control unit 130 sends the interrupt signal, it sends an interrupt signal with a different message according to the magnetic flux sensing result of the magnetic flux sensor 120. That is to say, when the magnetic flux sensing result of the magnetic flux sensor 120 is "1", the interrupt signal sent by the control unit 130 carries a message related to the magnetic flux sensing result "1". On the other hand, when the magnetic flux sensing result of the magnetic flux sensor 120 is "0", the interrupt signal sent by the control unit 130 will have a message related to the magnetic flux sensing result "0,".

When the processing unit 140 receives the interrupt signal, it will read the current motion information of the motion sensor 110. That is, the processing unit 140 executes the related application to read the current motion information of the motion sensor 110. Then, the application determines the operation status based on the information related to the magnetic flux sensing result in the interrupt signal. For example, FIG. 5 is a flow chart of a method of determining an operational state in accordance with an embodiment of the present invention. 6A-6C are schematic diagrams showing a flip angle of a first body according to an embodiment of the invention.

Referring to FIG. 5, in step S510, the application determines whether to perform step S520 or step S530 according to the interrupt signal having a message related to the magnetic flux sensing result. When the magnetic flux sensing result is "1", step S520 is performed; when the magnetic flux sensing result is "0", step S530 is performed.

In step S520, it is determined that the operation state is the squat mode or the tablet mode. When the Z-axis vector is "-1 ± sin θ", it is determined as the squat mode as in step S521. When the Z axis When the vector is "1 ± sin θ", it is determined as the tablet mode as in step S522.

The above θ is the flip angle obtained by the motion sensor 110, as shown in Fig. 6A. In the tablet mode, the obtained flip angle θ will fall within the first predetermined range, for example, 20° to 160°. In the pick-up mode, the flip angle does not fall within the first preset range (20°~160°).

In step S530, it is determined that the operation state is the floating mode or the viewing mode. When the Z-axis vector is "1 ± sinX", it is determined to be in the floating mode as in step S531. When the Z-axis vector is "-1 ± sinY", it is determined as the viewing mode as in step S532.

The above-described inversion angle X is as shown in Fig. 6B, and the above-described inversion angle Y is as shown in Fig. 6C. In the floating mode, the flip angle X will fall within the second preset range, for example, 45° to 90°. In the viewing mode, the flip angle Y will fall within the third preset range, for example, 100° to 135°.

After the application determines the operating state, the operating signal corresponding to the operating state can be transmitted to the control unit 130. Alternatively, the application records a value corresponding to the operational status in a register, and the control unit 130 reads the value from the register to obtain the determined operational status. The above registers may be one, two or more, and are not limited herein.

In addition, in the above control method, the control unit 130 also controls the flipping of the display screen provided on the touch display panel 210 according to the motion information. That is to say, the display screen of the touch display panel 210 is correspondingly flipped with the angle at which the first body 21 is flipped.

Moreover, in other embodiments, the motion sensor 110 can be coupled to the control unit 130 without passing through the processing unit 140. Figure 7 is a block diagram of a control device in accordance with another embodiment of the present invention. In the control device 70 of FIG. 7, the control unit 130 can be coupled to the motion sensor 110 through an internal integrated circuit (I ² C) bus bar. The motion information of the motion sensor 110 is read by the control unit 130, and the control unit 130 determines the portable electronic device according to the magnetic flux sensing result of the magnetic flux sensor 120 and the motion information obtained by the motion sensor 110. The operating state of 20 is determined to enable or disable at least one input unit depending on the operating state.

In summary, in the above embodiment, the motion sensor and the magnetic flux sensor are combined to determine the operating state of the portable electronic device, and the magnetic flux sensor is used to detect whether the first body is generated relative to the second body. The opening and closing action is further based on the magnetic flux sensing result, and the operating state is judged based on the motion data. According to this, the operating state of the portable electronic device can be correctly recognized, and it is determined whether the input unit is to be enabled or disabled.
