Figures 1A to 1E show the portable electronic device 100 operating in different modes (closed mode in Figure 1A, tablet mode in Figure 1B, and laptop mode in Figure 1C) according to an embodiment of the disclosure document. , The upright mode in Figure 1D and the tent mode in Figure 1E). In an embodiment, the portable electronic device 100 may be a desktop computer, a notebook computer, a morphing laptop, a palmtop computer, or an electronic dictionary, but the present disclosure is not limited to this.

With continued reference to FIGS. 1A to 1E, the portable electronic device 100 includes a display component 110 and an input component 120. In one embodiment, the input component 120 may be a keyboard, a touch pad, a track point (Track Point or Track Stick), a digital graphics tablet, a trackball, or a combination thereof. However, the disclosure is not limited thereto.

Referring to FIGS. 1A to 1E, the display component 110 has a display plane 111 and the input component 120 has an input plane 121. According to user needs, the portable electronic device 100 can operate in different modes. These modes are determined by the opening and closing angle θ formed by the display plane 111 and the input plane 121. Referring to FIGS. 1A to 1E, according to a change in the opening and closing angle θ, the portable electronic device 100 can be operated in the closed mode (first mode) in FIG. 1A, the tablet mode (second mode) in FIG. 1B, The laptop mode (third mode) in FIG. 1C, the upright mode (fourth mode) in FIG. 1D, and the tent mode (fifth mode) in FIG. 1E. Corresponding to different modes, components (such as the display component 110 and the input component 120) in the portable electronic device 100 can have different switch states to meet different usage requirements.

The five modes proposed in the above embodiments are merely illustrative. In practical applications, the portable electronic device 100 is not limited to the entirety including the above five modes. In one embodiment, the portable electronic device 100 has At least two of the above five modes.

Figures 2A and 2B are schematic diagrams of different modes of a sensing component in a portable electronic device according to an embodiment of the disclosure. In FIG. 2A, the portable electronic device 100 is operated in the closed mode shown in FIG. 1A, and the opening and closing angle θ is 0 degrees at this time. In addition, in FIG. 2B, the portable electronic device 100 is operated in the tablet mode shown in FIG. 1B, and at this time, the opening and closing angle θ is 360 degrees. Generally speaking, a magnetic object can be used to determine whether the portable electronic device 100 is operated in a closed mode with an opening and closing angle θ of 0 degrees (as shown in FIG. 1A) or a flat mode with an opening and closing angle θ of 360 degrees (such as in FIG. 1A). Figure 1B). However, as the panel technology gradually becomes thinner, the magnetic force measured in the closed mode and the flat mode may be too close. Therefore, the improvement proposed in this case will use several acceleration sensing modules to sense the opening and closing angle θ of the portable electronic device 100 plus the correction of the magnetic field lines, as described later.

Refer to Figure 2A. The portable electronic device 100 further includes a processing component 130. The processing component 130 is electrically connected to the display component 110 and the input component 120. In an embodiment, the processing component 130 may be an ARM processor, a SoC control chip, a MIPS processor, an x86 processor, a DSP processor, or a PowerPC processor. However, This disclosure is not limited to this.

Continue to refer to Figure 2A. The processing component 130 can be used to determine the opening and closing angle θ of the display component 110 and the input component 120 to determine that the portable electronic device 100 is operated in the five modes shown in FIGS. 1A to 1E (ie, the closed mode in FIG. 1A). , The tablet mode in FIG. 1B, the laptop mode in FIG. 1C, the upright mode in FIG. 1D, and the tent mode in FIG. 1E). According to the above five modes, the processing component 130 may disable or enable the display component 110 and the input component 120 according to the requirements of the mode. In one embodiment, the processing component 130 enables or disables the automatic rotation function of the display component 110 correspondingly according to the requirements of the five modes.

Refer to Figure 2A. The display component 110 includes a first acceleration sensing module 112, a first magnetic object 113a, and a second magnetic object 113b. The first magnetic object 113a and the second magnetic object 113b are spaced apart by a distance D1. In one embodiment, the first magnetic object 113a and the second magnetic object 113b may be magnets. In one embodiment, the distance D1 is preferably less than 2 cm, but the present disclosure is not limited thereto. It must be noted that the polarities of the first magnetic object 113a and the second magnetic object 113b in the vertical arrangement position of the display plane 111 need to be the same (see the description of FIGS. 3A and 3B). For example, in the closed mode shown in FIG. 1A and FIG. 2A and the portable electronic device 100 is in a flat state, the first magnetic object 113a and the second magnetic object 113b are both S poles up and N poles down Settings.

Refer to Figure 2A. The input component 120 includes a second acceleration sensing module 122 and a magnetic force sensing module 124. The magnetic force sensing module 124 is configured to sense a magnetic force value from the first magnetic object 113a or the second magnetic object 113b. In one embodiment, the magnetic force sensing module 124 may be a Hall effect sensor or a magnetoresistive sensor. However, the present disclosure is not limited to this.

Continue to refer to Figure 2A. According to the opening and closing of the portable electronic device 100, the first acceleration sensing module 112 and the second acceleration sensing module 122 respectively disposed on the display component 110 and the input component 120 will sense the direction of the acceleration of gravity and judge the display. The opening and closing angle θ between the plane 111 and the input plane 121. In one embodiment, the first acceleration sensing module 112 and the second acceleration sensing module 122 may be an accelerometer or any acceleration sensing component.

Please refer to Figure 2B. The portable electronic device 100 operates in the tablet mode shown in FIG. 1B. Referring to Figures 2A and 2B at the same time, in the closed mode (such as Figure 1A) or the flat mode (such as Figure 1B) where the opening and closing angle θ is 0 degrees, at the input plane The magnetic force sensing module 124 on 121 is aligned with the first magnetic object 113 a on the display plane 111. In the closed mode or the tablet mode, the first magnetic object 113a is close enough to the magnetic force sensing module 124 and the magnetic force value can be sensed. Therefore, in addition to using the first acceleration sensing module 112 and the second acceleration In addition to the sensing module 122 to determine the opening and closing angle θ of the portable electronic device 100, the magnetic sensing module 124 is used to determine whether the portable electronic device 100 is operating in a closed mode with an opening and closing angle θ of 0 degrees or Flat mode with an opening and closing angle θ of 360 degrees. In one embodiment, if the magnetic force value sensed by the magnetic force sensing module 124 is within the first magnetic force range, the processing component 130 determines that the portable electronic device 100 is operating in the closed mode. In an embodiment, if the magnetic force value sensed by the magnetic force sensing module 124 is within the second magnetic force range, the processing component 130 determines that the portable electronic device 100 is operated in the tablet mode. In one embodiment, the minimum value of the first magnetic force range is greater than the maximum value of the second magnetic force range.

Refer to Figure 2B. However, when the portable electronic device 100 is placed on the iron table 200 in the tablet mode with the opening and closing angle θ of 360 degrees, the interaction between the iron table 200 and the first magnetic object 113a will generate a strong magnetic force value. As a result, the magnetic force value sensed by the magnetic force sensing module 124 falls within the first magnetic force range, so that the processing component 130 mistakenly determines the tablet mode as the closed mode. Therefore, the second magnetic object 113b is used to offset the interaction between the iron table 200 and the first magnetic object 113a, thereby correcting the judgment of the processing component 130.

Figures 3A and 3B are schematic diagrams of magnetic object polarities according to an embodiment of the disclosure. Figures 3A and 3B are used to illustrate that the polarities of the first magnetic object 113a and the second magnetic object 113b on the display plane 111 must be the same. As shown in FIG. 3A, the polar directions of the first magnetic object 113a and the second magnetic object 113b are aligned. Therefore, the magnetic field lines 31a of the first magnetic object 113a and the magnetic field lines 31b of the second magnetic object 113b are mutually exclusive due to the same polarity direction, whereby the magnetic force X is reduced due to the mutual repulsion of the magnetic field lines 31a and the magnetic field lines 31b. The magnetic force sensing module 124 sensed that the value of the magnetic force X was low. Therefore, the second magnetic object 113 b can offset the magnetic force X generated when the portable electronic device 100 is placed on the iron table 200.

Continue to refer to Figure 3B. As shown in FIG. 3B, the polar directions of the first magnetic object 113a and the second magnetic object 113b are not aligned. Therefore, the magnetic field lines 32a of the first magnetic object 113a and the magnetic field lines 32b of the second magnetic object 113b will attract each other due to different polar directions, whereby the magnetic force Y will increase due to the attraction of the magnetic field lines 32a and the magnetic field lines 32b, and the magnetic force sensing module 124 sensed that the value of the magnetic force Y is high. Therefore, the second magnetic object 113b increases the magnetic force Y generated when the portable electronic device 100 is placed on the iron table 200.

Figures 4A to 4D are top views of the positions of the magnetic objects according to the disclosure. As described above, in the closed mode in which the opening and closing angle θ of the portable electronic device 100 is 0 degrees or the tablet mode in which the opening and closing angle θ is 360 degrees, the magnetic force sensing module 124 on the input plane 121 is The first magnetic object 113a is aligned on the display plane 111. FIG. 4A is a top view of the first magnetic object 113a and the second magnetic object 113b on the display module 110 according to FIG. 2A.

Referring to FIG. 4B, in order to more effectively offset the excess magnetic force generated when the portable electronic device 100 is placed on the iron table 200, the display module may be further opposed to the first magnetic object 113a and the second magnetic object 113b on different sides. A third magnetic object 113c is arranged on the other side. The distance D2 between the third magnetic object 113c and the first magnetic object 113a is equal to the distance D1 between the second magnetic object 113b and the first magnetic object 113a. The distance D2 is preferably less than 2 cm. However, this disclosure is not limited to this. Referring to FIG. 4B, the first magnetic object 113a, the second magnetic object 113b, and the third magnetic object 113c may be arranged in a line.

Referring to FIG. 4C, the fourth magnetic substance 113d and the fifth magnetic substance 113e can be further added. The distances between the fourth magnetic object 113d and the fifth magnetic object 113e and the first magnetic object 113a are the distance D3 and the distance D4, respectively, and are equal to the distance D1 and the distance D2. The distance D3 and the distance D4 are preferably less than 2 cm, but the present disclosure is not limited to this. The second magnetic object 113b, the third magnetic object 113c, the fourth magnetic object 113d, and the fifth magnetic object 113e are arranged symmetrically around the first magnetic object 113a.

With continued reference to FIG. 4D, the sixth magnetic substance 113f, the seventh magnetic substance 113g, the eighth magnetic substance 113h, and the ninth magnetic substance 113i can be further added. The distance from the second magnetic substance 113b to the ninth magnetic substance 113i is equal to the distance of the first magnetic substance 113a, preferably less than 2 cm, but the present disclosure is not limited to this. Similar to FIGS. 4C and 4D, the second magnetic object 113b to the ninth magnetic object 113i are arranged symmetrically around the first magnetic object 113a.

FIG. 5 is a schematic diagram of a portable electronic device according to an embodiment of the disclosure. In an embodiment, the display device 110 in the portable electronic device 100 as shown in FIGS. 1A to 1E may further include a virtual input 115 which is displayed on the screen in the tent mode of FIG. 1E. In an embodiment, the virtual input 115 may also be displayed on the screen in the tablet mode in FIG. 1B, the laptop mode in FIG. 1C, or the upright mode in FIG. 1D according to user preferences. However, this disclosure is not limited to this. The input component 120 may further include a light emitting module 125. In one embodiment, the portable electronic device 100 disables the light emitting module 125 in the closed mode, the tablet mode, the upright mode, and the tent mode, and the portable electronic device 100 turns on the input component 120 in the laptop mode. The light emitting module 125 is not limited to this embodiment. In other embodiments, in the tablet mode, the laptop mode, the upright mode, and the tent mode, the light-emitting module 125 of the input component 120 may be enabled or disabled according to user requirements.

FIG. 6 is a flowchart of the control method shown in one embodiment of the present disclosure. The control method shown in FIG. 6 can be applied to the portable electronic device 100 disclosed in the previous embodiment. Refer to Figures 2A and 6 at the same time. First, in step S601, the opening acceleration angle θ formed between the display plane 111 and the input plane 121 is sensed by the first acceleration sensing module 112 and the second acceleration sensing module 122 of the portable electronic device 100. In step S602, it is determined whether the opening and closing angle θ is within the first angle range or the second angle range. In an embodiment, the first angle range is between 0 degrees and 30 degrees, and the second angle range is between 340 degrees and 360 degrees. However, the disclosure is not limited thereto. If the determination in step S602 is YES, then step S603 is performed. In step S603, the magnetic force sensing module 124 is used to detect whether the magnetic force value is in the first magnetic force range M1 or the second magnetic force range M2. In one embodiment, the first magnetic force range M1 is greater than 50 Gauss, and the second magnetic force range M2 is less than 30 Gauss. However, the present disclosure is not limited thereto. On the other hand, if the determination in step S602 is no, the process proceeds to step S701, and the operation of step S701 will be fully explained in the subsequent embodiments.

In step S603, if it is determined that the magnetic force value is in the first magnetic force range M1, the process proceeds to step S604a. In step S604a, the processing component 130 determines that the portable electronic device 100 is operating in the closed mode, and the processing component 130 disables the display component 110 and the input component 120. In one embodiment, when the processing component 130 disables the input component 120, the light-emitting module 125 of the input component 120 is also disabled.

If it is determined that the magnetic force value is in the second magnetic force range M2, the process proceeds to step S604b. In step S604b, the processing component 130 determines that the portable electronic device 100 is operating in the tablet mode, and the processing component 130 disables the input component 120 and enables the display component 110. In one embodiment, the display screen on the display unit 110 can be rotated according to the direction of gravity according to the needs of the user. Through the above-mentioned two-stage calculation by the first acceleration sensing module 112, the second acceleration sensing module 122, and the magnetic sensing module 124, it is possible to more accurately determine whether the portable electronic device 100 is in a closed mode or a tablet. Mode operation can avoid the problem that the opening and closing angles θ detected in the above two modes (closed mode and tablet mode) are too similar and difficult to distinguish.

FIG. 7 is a flowchart of a method for a portable electronic device according to an embodiment of the disclosure. Refer to Figures 2A and 7 at the same time. When the portable electronic device 100 is operated in a laptop mode, an upright mode, or a tent mode, the magnetic force sensing module 124 can hardly sense the magnetic force. Therefore, in step S701, the first acceleration sensing module 112 and the second acceleration sensing module 122 are mainly used for judgment.

In step S701, it is determined that the opening and closing angle θ sensed by the first acceleration sensing module 112 and the second acceleration sensing module 122 is within the third angle range R3, the fourth angle range R4, or the fifth angle range R5. Based on this, it is determined whether the portable electronic device 100 is operating in a laptop mode, an upright mode, or a tent mode. In an embodiment, the third angle range R3 is between 30 and 180 degrees, the fourth angle range R4 is between 180 and 225 degrees, and the fifth angle range R5 is between 225 and 340 degrees. However, this disclosure is not limited to this. .

If it is determined that the opening / closing angle θ is within the third angle range R3, the process proceeds to step S702a, the processing component 130 determines that the portable electronic device 100 is operated in the laptop mode, and both the display component 110 and the input component 120 remain on.

If it is determined that the opening and closing angle θ is in the fourth angle range R4, the process proceeds to step S702b, the processing component 130 determines that the portable electronic device 100 is operating in the upright mode, the display component 110 remains on, the input component 120 is disabled, and virtual input is enabled 115.

If it is determined that the opening and closing angle θ is within the fifth angle range R5, the process proceeds to step S702c, the processing component 130 determines that the portable electronic device 100 is operating in the tent mode, the display component 110 remains on, the input component 120 is disabled, and virtual is enabled Enter 115. At this time, the display screen on the display component 110 can be rotated 180 degrees to facilitate viewing by the user.
