Description

Electronic device including flexible display

Various embodiments of the present disclosure relate to an electronic device including a flexible display that slides.

Due to the development of information and communication technology and semiconductor technology, various functions are being integrated into one portable electronic device. For example, the electronic device may implement not only a communication function, but also an entertainment function such as a game, a multimedia function such as music/video playback, a communication and security function for mobile banking, schedule management, and an electronic wallet function. Such electronic devices are being miniaturized so that users can conveniently carry them.

As the mobile communication service expands to the multimedia service area, there is a need to increase the size of the display of the electronic device in order for the user to fully use the multimedia service as well as the voice call or short message. However, the size of the display of the electronic device has a trade-off relationship with the miniaturization of the electronic device.

In a flexible display, the screen can be flat or curved by winding, folding, or bending the panel. The flexible display may be implemented as a rollable display, a bendable display, a foldable display, a slideable display, and the like. Electronic devices including such flexible displays can be applied to TVs, automobile displays, wearable devices, etc. as well as mobile devices such as smart phones and tablet PCs, and the field of application is expanding.

An electronic device (eg, a portable terminal) includes a flat display or a display having a flat surface and a curved surface. An electronic device including a display may have a limitation in realizing a screen larger than the size of the electronic device due to the fixed display structure. Accordingly, an electronic device including a foldable or rollable display is being researched.

In implementing a rollable electronic device, it may be difficult to check the degree of movement while enabling the housings of the electronic device to move (eg, slide) relative to each other. For example, when a magnet or a sensor is used while securing portability of the electronic device through miniaturization, a large amount of mounting space may be occupied in the electronic device. In addition, it may be necessary to additionally attach tapes that can be sensed in the entire display area.

In implementing a rollable electronic device, if a mechanical structure is added to measure the degree of sliding of the display, the size of the electronic device may increase. Also, if a grip sensor and an illuminance sensor are mounted in order to know the spread of the display, and a software algorithm is added, the accuracy such as resolution may be reduced. If expensive components are added to clearly and intuitively measure the degree of slide movement of the display, additional stacking or separate devices are added to the display stage, resulting in increased weight or insufficient mounting space.

According to various embodiments of the present disclosure, it is possible to provide an electronic device capable of confirming the degree of movement of the display.

In another embodiment, when moving from the closed state to the open state, the first elastic member 131 may move (eg, slide contact) while in contact with the rear case 121a. For example, if the foreign material is introduced into the gap between the second display area A2 and the rear case 121a in the closed state, when moving to the open state, the first elastic member 131 removes the foreign material from the second housing (102) can be discharged to the outside.

According to an embodiment, in the closed state, the second elastic member 133 may contact the surface of the display 103 to substantially seal the space between the display 103 and the rear case 121a. According to an embodiment, the second elastic member 133 may be made of a low-density elastic body such as a sponge or a brush, so that the surface of the display 103 may not be damaged even if it comes into direct contact with the display 103 . In another embodiment, as the first housing 101 gradually moves to an open state, a gap between the rear case 121a and the second elastic member 133 may increase. For example, the display 103 may not substantially contact or rub against the second elastic member 133 , and the second display area A2 may be exposed to the outside of the second housing 102 . When the first housing 101 is in an open state, the first elastic member 131 may come into contact with the second elastic member 133 to block the inflow of foreign substances.

For example, the number of turns of approximately five adjacent coils 412 may be arranged to increase or decrease gradually. A plurality of coils included in the conductive circuit unit 411 may be represented as channels (eg, Ch1, Ch2, Ch3, Ch4, and Ch5). For example, a portion indicated by a dotted line in FIG. 4C may be illustrated in a form in which a plurality of coils are connected to one channel with reference to FIG. 4D .

According to various embodiments, the conductive circuit unit 411 includes an FPCB (hereinafter, a coil FPCB) including a coil and a magnetic sheet (eg, 413 in FIG. 4B or a magnetic sheet in FIG. 4B) and an attachment (eg, to attach the coil and the magnetic sheet) For example, the hatched mark of FIG. 4B or Adh of FIG. 4B) may be included, and a non-metal sheet 420a or the like may be included at the lower end of the conductive circuit part 411 .

According to various embodiments, the conductive circuit unit 411 may be positioned on at least one area of the second display area 420 . The conductive circuit unit 411 may be located on the rear surface of the second display area 420 and may not be visible from the outside when the second display area 420 slides.

According to various embodiments, the conductive circuit unit 411 may transmit and/or receive a signal having a frequency of a specified band. For example, a signal having two frequency components f0=593Khz and f1=625Khz may be transmitted. The resonant circuit unit 421 responds to the signal transmitted by the conductive circuit unit 411 and the control unit (eg, the processor 120 of FIG. 9 ) may determine the degree of slide movement of the display. 5A and 5B , it shows how the conductive circuit part 411 can move with respect to the direction in which the display 400 moves.

Referring to FIG. 5A , the output value of the control unit (eg, the processor 120 of FIG. 9 ) generated when the resonant circuit unit 421 meets a signal including different frequencies transmitted by the conductive circuit unit 411 for each frequency band. The degree of slide movement of the second display area 420 may be checked as a summation value. According to another embodiment, the signal including a plurality of different frequencies transmitted by the conductive circuit unit 411 and the resonant circuit unit 421 meet and generate an output value of the control unit (eg, the processor 120 of FIG. 9 ) is calculated at each frequency. The degree of slide movement of the second display area 420 may be checked by checking a peak having a maximum or minimum value when displayed for each band.

According to various embodiments, the resonance circuit unit 421 may be formed of an L-C circuit. The resonance circuit unit 421 may further include a magnetic sheet 423 . The resonance circuit unit 421 may be positioned on at least a portion of the second structure 420 facing the second display area 420 , and may include a non-metallic sheet 421a.

By detecting the intensity of the slide movement degree can be detected.

According to various embodiments, the control unit (eg, the processor 120 of FIG. 9 ) slides the second display area 420 by measuring an area where at least a portion of the conductive circuit unit 411 overlaps the resonance circuit unit 421 . level can be checked. The overlapping region is a region when a signal of a specified frequency band generated by the first coil pattern (eg, Ch1 ( 412a ) of FIG. 4C ) of the conductive circuit unit 411 meets the resonance circuit unit 421 (eg, FIG. 5A ) One end of the N-th coil pattern (not shown) of the conductive circuit unit 411 may include a region (eg, FIG. 5B ) overlapping the resonance circuit unit 421 due to the sliding movement of the second display region 420 from the .

According to various embodiments, when the second display area 420 slides to a closed state or an open state (eg, FIG. 2 ), the controller (eg, the processor 120 of FIG. 9 ) controls at least the conductive circuit unit 411 . A region (eg, FIGS. 5A and 5B ) partially overlapping the resonance circuit unit 421 may be measured. When the conductive circuit unit 411 and the resonant circuit unit 421 face each other (eg, the processor 120 of FIG. 9 ) and is converted from a magnetic field to an electric field, the controller (eg, the processor 120 of FIG. 9 ) may measure a related amplitude value.

According to various embodiments, the overlapping regions (eg, FIGS. 5A and 5B ) may be identified using at least one frequency included in a signal transmitted from the conductive circuit unit 411 . The controller (eg, the processor 120 of FIG. 9 ) may sense an amplitude value proportional to the area where the conductive circuit unit 411 and the resonance circuit unit 421 overlap. As shown in [Table 1], as an example, each amplitude value of a signal having two frequency components f0=593Khz and f1=625Khz can be checked. The control unit (eg, the processor 120 of FIG. 9 ) may determine which position between Ch1 to Ch5 corresponds to by summation of amplitude values (frequency variable amplitudes, Table 1, Table 1) for each frequency component.

FN, Ch N+1 0≤N≤4	frequency variable amplitude

According to various embodiments, when the specified frequency band is increased from 2 to 5, accuracy (eg, resolution) may be further increased. For example, if the mounting space is small, a total of 5 frequency bands from F0 to F4 can be designated and operated using the designated frequency variables of F0 and F1. As the frequency band is subdivided, the accuracy can be improved in a small mounting space. For example, you can change 595Khz to 560Khz among the two specified frequency values, and set it to five resonant frequency values, approximately F0 = 530Khz, F1=560Khz, F2=590Khz, F3=625Khz, and F4=650Khz. A frequency for each channel's coil FPCB (eg, 412 in FIG. 4 ) and five resonance frequencies may be matched.

Referring to FIG. 6 , the x-axis moves to the open state (eg, FIG. 5B ) of the second display area 420 from Ch(channel)1 to Ch5 and the area facing the resonance circuit unit 421 is sequentially described. can The y-axis may represent a value for a signal of a specific frequency band that can be measured by the controller (eg, the processor 120 of FIG. 8 ). For example, when N=4 (N is a natural number), Ch(1~N+1) is set from 1 to 5, and frequency band F(0~N, N is a natural number) is set from F0 to F4. When the band and each Ch are matched with each other, it is known that there is a specific Ch whose value of 2.1 million or more is measured among the amplitude values sensed by the controller (eg, the processor 120 of FIG. 9 ) for one frequency band. can As an example, looking at a graph consisting of amplitude values for the frequency band F0, a peak point having a value of about 2000000 or more is shown in the about Ch1 part of the x-axis, and in Ch1,2, which is a larger range than the about Ch1 part of the x-axis. Up to Ch5, it is shown as having a value of about 2000000 or less. In other words, when the conductive circuit unit 411 faces the resonance circuit unit 421 in Ch1, the signal for the frequency band F0 senses a peak value in the control unit (eg, the processor 120 of FIG. 8 ) and detects the second It can be recognized that the display area 420 is located at the corresponding position.

Referring to FIG. 6 , it can be seen that when a value of 700,000 or less is measured among amplitude values for one frequency band, it is located between two adjacent Chs. For example, looking at a graph consisting of amplitude values for the frequency band F2, a peak value of about 700000 or less is shown in about Ch 2 and 3 parts of the x-axis, and a peak value of about 2000000 or more is shown in about Ch3 part of the x-axis. You can see that the value is displayed. In other words, when the signal for the frequency band F2 faces the conductive circuit part 411 with the resonant circuit part 421 in Ch2,3, the control unit (eg, the processor 120 in FIG. 8) is the lowest peak value It can be sensed and recognized that the second display area 420 is located at the corresponding position.

Referring to FIG. 6, it can be seen that Ch1 is at F0 frequency, Ch2 is at F1 frequency, Ch3 is at F2 frequency, Ch4 is at F3 frequency, and Ch5 is the maximum peak value at F4 frequency. have. Similarly, between Ch1 and Ch2 (eg Ch1,2 in FIG. 6), between Ch2 and Ch3 (eg Ch2,3 in FIG. 6), between Ch3 and Ch4 (eg Ch3,4 in FIG. 6), and between Ch4 and Ch5 It can be seen that the frequency bands F1, F2, F3 and F4 have minimum peak values when matched to (eg, Ch4,5 of FIG. 6 ).

According to various embodiments, the amplitude value measured by the controller (eg, the processor 120 of FIG. 8 ) is proportional to the size of the area where the coil FPCB (eg, 412 in FIG. 4B ) and the LC resonance circuit 421 overlap can confirm. For example, Ch1 may face the resonance circuit unit 421 first among other Ch, and an overlapping area may gradually increase due to sliding of the second display area 402 . Referring to Table 1, in Ch1, the amplitude value is about 2000000, which may have a larger value than other Ch.

7A and 7B are perspective views of an electronic device according to various embodiments of the present disclosure;

According to various embodiments, through the present disclosure, in order to know the degree of movement of the display 400 according to the sliding movement of the first structure, the conductive circuit part ( 411), and a control unit (eg, in FIG. 8 ) to control the degree of movement of the display 400 through the resonance circuit unit 421 disposed in one area of the second structure 402 while facing the second display area 402 . It can be known through the processor 120). For information on the first structure 101 , the second structure 402 , the second display area 402 , the conductive circuit unit 411 , and the resonance circuit unit 421 , reference may be made to the descriptions of FIGS. 1 to 5 .

According to various embodiments, a front view ( Example: top of FIG. 7A ) and side views (eg bottom of FIG. 7A ). For the overlapping region 701 , reference may be made to the descriptions of FIGS. 4 to 5 .

According to various embodiments, the overlapping area 701 may gradually increase by sliding movement of the second display area 420 from a closed state (eg, FIG. 5A ) to an open state (eg, FIG. 5B ). For example, the conductive circuit part 411 may include one or more adjacent coils Ch1 to Ch5, and Ch1 (eg, the conductive circuit part 411 of FIG. 4 ) by sliding movement of the second display area 420 ). to Ch5 may face the resonance circuit unit 421 in turn.

Referring to FIG. 7B , as an example, a state in which an LC resonance circuit (eg, the resonance circuit part 421 of FIG. 4 ) faces with respect to Ch1 (eg, the conductive circuit part 411 of FIG. 4 ) is shown.

According to another embodiment, accuracy (eg, resolution) may be increased by adjusting each coil pattern in the coil FPCB (eg, 412 in FIG. 4B ). For example, you can increase the accuracy by adjusting the winding (number of turns) of the coil. For example, a current of about 2.6 mA may be applied based on a transmission signal having a frequency of about 593 Khz. In this case, when a 2.6 mA current is applied, the data value recognized by the controller (eg, the processor 120 of FIG. 9 ) may be set to about 1.8 million. For example, when it is assumed that the maximum data value that can be measured in the F0 frequency band is about 2 million, and the accuracy is measured to about 20000, which is a scale of about 1% of about 2 million, when only the F0 frequency band is confirmed There may be deviations in checking the degree of movement of the slide. In order to increase the accuracy, an F1 frequency band may be additionally added. For example, a value of about 1 million may be used as a maximum data value and a value of about 1 million may be scaled by about 1% to measure resolution. Through the F0 and F1 frequency bands, it can be checked whether the coil FPCB (eg, 412 in FIG. 4B ) is matched, whether there is a crack in the coil pattern, and the like. For example, the controller (eg, the processor 120 of FIG. 9 ) may perform precise measurement by reducing the scale of about 1% to the scale of about 0.5% in sensing the overlapping area. For example, even in the designated frequency bands F0 and F1, the resolution can be measured on a scale of about 0.5%.
