The gear pattern piece of the first main gear 341 may pass through the first center support 330 and be meshed with the internal gear 321 of the first support gear internal gear 320. Internal gear 321 may be formed on one side, for example, at a bottom of a curved hole (for example, one end of which is round such that the main gear can be inserted into the curved hole as part of an arc) provided on one side of the first inner support gear 320. In the description, it has been exemplified that the inner gear 321 is formed in a portion n from the bottom of the first internal support gear 320, although the disclosure is not limited thereto. When a force is applied to the first inner support gear 320 (or the first support housing 310 and the first housing 110 coupled to the first inner support gear 320) in a first direction (for example, a clockwise direction clock with reference to the illustrated drawing), as illustrated in state 903, the first inner support gear 320 may be inclined at a first angle (eg, 45 degrees) relative to a longitudinal center line of the first center support 330 When the first inner support gear 320 is tilted at the first angle, the same rotation is transmitted to the second inner support gear 370, and the second inner support gear 370 may be tilted at the first angle relative to the center line. of the first center support 330 (or the center line of the second center support 360).

According to various embodiments, the first inner support gear 320 (or the second inner support gear 370) may be formed to be smaller than the first center support 330 (or the second center support 360) while having a semi-elliptical shape and, as illustrated in Figure 9B, the imaginary center axes of rotation 911 and 912 of the first inner support gear 320 may be located above the first center support 330 when the first inner support gear 320 (or the second gear inner support bracket 370) rotates at a point that deviates from the center line of the first center support 330 (or the second center support 360).

In accordance with various embodiments, state 905 corresponds to a view illustrating a shape of the second inner support gear 370 coupled to the second center support 360. A portion of the second main gear gear pattern piece 342 deviating toward the right of the longitudinal center line of the Second center support 360 is meshed with internal gear 371 of second internal support gear 370 and can be rotated by external force. For example, when a force that is stronger than in state 903 is applied continuously, as illustrated in state 907, the second inner support gear 370 may be disposed parallel to the longitudinal center line of the second center support 360. As the second inner support gear 370 rotates, the first inner support gear 320 can be rotated in a direction opposite to the direction of rotation of the second inner support gear 370. Consequently, as illustrated, the flat surfaces of the The first inner support gear 320 and the second inner support gear 370 may be arranged parallel to the longitudinal center lines of the center supports 330 and 360 (or perpendicular to the transverse center lines of the center supports 330 and 360).

As described above, since the first inner support gear 320 and the second inner support gear 370 are engaged at locations that are spaced from the centers of the center supports 330 and 360 (for example, locations that offset toward the right peripheries or right peripheries of center supports 330 and 360) through the first main gear 341 and the second main gear 342, as illustrated in Figure 9B, the imaginary center axes of rotation 911 and 912 may be located at a height specific height from the surfaces of the first shell 110 and the second shell 120 to the top side (or a specific height from the rear surface of the screen 50 to the top side, a specific height from the top surface of the screen 50 to the side lower, or a specific height to the upper side of the transverse center lines of the center supports 330 and 360) when the p The first main gear 341 and the second main gear 342 rotate. Alternatively, the imaginary center axes of rotation 911 and 912 may be formed on top of the lower surface of the lower end surface of the screen 50 when viewed from the top to the bottom with reference to the illustrated drawing.

In accordance with various embodiments, the shapes and sizes of the internal gears 321 and 371 of the first internal support gear 320 and the second internal support gear 370 can be adjusted for locations where the first internal support gear 320 and the second internal support gear 370 have to be arranged parallel to the center supports 330 and 360 and locations where the first inner support gear 320 and the second inner support gear 370 have to be arranged at 90 degrees with respect to the supports centers 330 and 360. Alternatively, the sizes of the curved holes of the rounded shapes, into which the main gear may be inserted, and the numbers and sizes of the grooves and threads of the internal gears 321 and 371 of the first gear inner support gear 320 and the second inner support gear 370 may vary according to the center supports 330 and 360.

In accordance with various embodiments, as illustrated at state 907, the shapes of the internal gears of the foldable flexible screen device 100 can restrict the maximum widths of rotation of the inner support gears 320 and 370. For example, the shapes of the internal gears may be constrained such that the inner support gears 320 and 370 rotate within 90 degrees with respect to the transverse center lines of the center supports 330 and 360. So, since the inner support gears 320 and 370 deviate to the left and right sides of the center supports 330 and 360, a gap of a specific size may be formed between the inner support gears 320 and 370 in a state that the first housing 110 and the second housing 120 are folded to face each other. The specific size gap can always keep a flex degree of a central screen area 50 at a constant value. For example, the central area of the screen 50 may be flexed to have a U-shape (or water drop shape) in a state that the first shell 110 and the second shell 120 are folded. Since the screen 50 is flexed in a U-shape, the screen 50 may be subjected to less stress, since the number of stress points (eg, an inflection point) that occurs in the central area of the screen 50 is smaller than another shape (for example, a lampshade that is folded into a raindrop shape or pot shape). Accordingly, the foldable flexible screen device 100 according to the disclosure can have a relatively long service life.
