Description

Technical Field

[0001] Embodiments of the present disclosure relate to an electronic device including a flexible display. Background Art

[0002] With the increasing demand for mobile communications, or with the increasing integration of electronic devices, the portability of electronic devices such as mobile communication terminals can be improved, and greater convenience can be provided when using multimedia functions. For example, as displays integrated with touch screens replace traditional mechanical (key-type) keyboards, electronic devices can become more compact when used as input devices. For example, since the mechanical keyboard can be omitted from the electronic device, the portability of the electronic device can be improved. Since the display area can be expanded to the area previously occupied by the mechanical keyboard, the electronic device can provide a larger screen while maintaining the same size and weight as when it has a mechanical keyboard.

[0003] Using an electronic device with a large screen can bring more convenience in, for example, web browsing or multimedia playback. A larger display can be used to output a larger screen. However, this approach may be limited by the portability of the electronic device. According to an embodiment, a display using an organic light-emitting diode can ensure the portability of the electronic device while providing a larger screen. For example, a display using or equipped with an organic light-emitting diode can achieve stable operation even if it is made very thin. Therefore, the display can be applied to an electronic device in a foldable, bendable, or rollable form. Summary of the Invention

In an embodiment, when the rack moves due to the drive of motor 630, front cover 221 fixed to the rack can move together. As a result, the magnet fixed to front cover 221 can move relative to the Hall IC fixed to frame cover 213. In an embodiment, the four Hall ICs included in detection sensor 660 (e.g., sensor 1, sensor 2, sensor 3, and sensor 4) can measure the strength of the magnetic field that changes according to the position of the relatively moving magnet, and thus estimate the movement distance of flexible display 620 or second housing 202.

[0122] In an embodiment, each Hall IC can measure the strength of the magnetic field on the x-axis, y-axis, or z-axis, and can use the measurement value of at least one of the three axes to estimate the position of the magnet and match it with the movement distance of the flexible display 620 or the second shell 202.

[0123] In an embodiment, when the motor 630 is operating normally, as shown in FIG. Figure 9 As shown, the moving distance of the flexible display 620 or the second housing 202 may have a 1:1 correspondence relationship according to the moving distance of the motor 630 , and the moving distance of the motor 630 and the moving distance of the magnet may correspond to each other.

[0124] Upon receiving the trigger signal, the electronic device 101 including the flexible display 620 according to the embodiment can control the motor 630 to be driven in the first direction or the second direction through the driving circuit 640, and can identify whether the flexible display 620 or the second housing 202 has reached the position corresponding to the trigger signal through the detection sensor 660. In an embodiment, when it is determined through the detection sensor 660 that the flexible display 620 or the second housing has reached the position corresponding to the trigger signal, the electronic device 101 including the flexible display 620 can complete the operation of the motor 630 corresponding to the trigger signal.

[0125] Figure 10 is a detailed block diagram illustrating detection of abnormal operation of the motor 630 by the monitoring circuit 650 according to an embodiment of the present disclosure. Figure 11a is a graph showing input current and output current at the time of normal operation of the motor 630 according to an embodiment of the present disclosure. Figure 11b is a graph illustrating input current and output current at the time of abnormal operation of the motor 630 according to an embodiment of the present disclosure.

[0126] refer to Figure 10 , the motor 630 according to the embodiment may include at least one coil 631 and 632 , and the driving circuit 640 may apply current and voltage to each of the at least one coil 631 and 632 included in the motor 630 .

[0127] In an embodiment, an induced electromotive force may be generated in at least one coil 631 and 632 included in the motor 630 due to the relative position of the coil 631 and 632 with respect to a magnet (not shown) included in the motor 630. In an embodiment, the output currents (Feedback Current 1 and 2) flowing through the at least one coil 631 and 632 may be the sum of the currents (RefCurrent 1 and 2) applied from the driver circuit 640 and the induced current. In an embodiment, the monitoring circuit 650 may obtain a signal of the input current applied to each of the at least one coil from the driver circuit 640.

[0128] In an embodiment, when an abnormal load greater than the driving force of the motor 630 is generated, a position difference occurs between a magnet (not shown) included in the motor 630 and the at least one coil 631 and 632, and thus a current inducing an electromotive force may flow through the at least one coil 631 and 632. In an embodiment, the monitoring circuit 650 can obtain signals of the output currents Feedback Current 1 and 2 flowing through the at least one coil 631 and 632.

[0129] For example, Figure 10As shown, the motor 630 may be a two-phase motor 630 and may include a first coil 631 and a second coil 632. The drive circuit 640 may apply input currents RefCurrent 1 and RefCurrent 2 to the first coil 631 and the second coil 632, respectively. In an embodiment, the monitoring circuit 650 may detect the input currents RefCurrent 1 and RefCurrent 2 applied from the drive circuit 640 to the first coil 631 and the second coil 632, respectively. In an embodiment, the monitoring circuit 650 may detect feedback currents Feedback Current 1 and Feedback Current 2 flowing through the first coil 631 and the second coil 632. In an embodiment, the monitoring circuit 650 may determine the operating state of the motor 630 using the input currents RefCurrent 1 and RefCurrent 2 and the output currents Feedback Current 1 and Feedback Current 2 corresponding to at least one of the first coil 631 and the second coil 632. Since the monitoring circuit 650 according to the embodiment can determine the operating state at every cycle of the current applied to the motor 630, abnormal operation can be detected faster than operation using other sensors.

[0130] refer to Figure 11a and Figure 11b In an embodiment, the monitoring circuit 650 may determine the operating state of the motor 630 using a phase difference (phase shift) over time between an input current and an output current corresponding to at least one coil included in the motor 630 .

[0131] For example, Figure 11a As shown in FIG. 1 , when the motor 630 operates normally, a phase difference (phase shift) over time hardly occurs between the input current Ref and the output current Feedback. Figure 11b As shown, when the motor 630 is operating abnormally, a phase difference (phase shift) over time occurs between the input current Ref and the output current Feedback. In an embodiment, when the phase difference (phase shift) over time between the input current Ref and the output current Feedback is greater than or equal to a threshold, the monitoring circuit 650 may determine that the motor 630 is operating abnormally and may transmit a signal related to the abnormal operation of the motor 630 to the processor 610.

[0132] The electronic device 101 including the flexible display 620 according to an embodiment can send a second drive signal to the drive circuit 640 based on the number of times a signal related to abnormal operation of the motor 630 is received being greater than or equal to a threshold number of times set based on the cumulative number of abnormal stops. In an embodiment, the threshold number of times can be set based on the cumulative number of abnormal stops. For example, if the cumulative number of abnormal stops is 0, the threshold number of times can be set to a first number (e.g., one or two times), thereby enabling rapid execution of abnormal stop and recovery control of the motor 630. For example, when the cumulative number of abnormal stops is one, two, or more, the threshold number of times can be set to a second number (e.g., three times) that is greater than the first number.

[0133] When the electronic device 101 including the flexible display 620 according to the embodiment receives a signal related to abnormal operation of the motor 630 , the electronic device 101 including the flexible display 620 may recognize the position of the flexible display 620 or the second housing (eg, the second housing 202 ) detected by the detection sensor 660 .

[0134] In an embodiment, when the position of the flexible display 620 or the second housing 202 detected by the detection sensor 660 is a position corresponding to the trigger signal, the electronic device 101 including the flexible display 620 may complete the operation of the motor 630 corresponding to the trigger signal.

[0135] In an embodiment, when the position of the flexible display 620 or the second shell 202 detected by the detection sensor 660 is different from the position corresponding to the trigger signal, the electronic device 101 including the flexible display 620 can send a second driving signal to the driving circuit 640 for abnormally stopping the driving of the motor 630.

[0136] In an embodiment, the electronic device 101 including the flexible display 620 may cumulatively count the number of times the second drive signal for abnormally stopping the driving of the motor 630 is transmitted or the number of abnormal stops. In an embodiment, the electronic device 101 including the flexible display 620 may select and execute at least one or more of at least one or more designated recovery controls based on the cumulative number of abnormal stops of the motor 630.

[0137] In an embodiment, after cumulatively counting the number of abnormal stops of the motor 630, or selecting and running at least one or more of at least one or more specified recovery controls, if a trigger signal is obtained again, the electronic device 101 including the flexible display 620 may send a first drive signal for driving the motor 630 to the drive circuit 640, and the drive circuit 640 may drive the motor 630 in response to the trigger signal.
