DETAILED DESCRIPTION

The aspects, features, and characteristics of some example embodiments of the present invention will be better understood in conjunction with the accompanying drawings. The present invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be more thorough and more complete, and will more fully convey the scope of the present invention to those skilled in the art.

FIGS. 1 to 3B are perspective views of a display apparatus according to some example embodiments of the present invention. FIG. 1 illustrates a display apparatus 10 in a closed mode (hereinafter, referred to as a “first operation mode”). FIG. 2 illustrates the display apparatus 10 in an opened mode (hereinafter, referred to as a “second operation mode”). FIG. 3A illustrates the display apparatus 10 folding in the first operation mode. FIG. 3B illustrates the display apparatus 10 folding in the second operation mode.

As illustrated in FIGS. 1 and 2, the display apparatus 10 includes a flexible display module 100, a supporting member 200, housings 300, and guide members (see reference numeral 400 in FIG. 7A). The flexible display module 100 includes a first display part 110, a second display part 120, and a third display part 130.

The flexible display module 100 may be folded and rolled. The flexible display module 100 may include an organic light emitting device. Although the flexible display module 100 may include a touch screen panel, the components included in the flexible display module 100 are not limited thereto.

The supporting member 200 includes a first supporting part 210, a second supporting part 220, and a hinge 230. Housings 300 include a first housing 310 and a second housing 320. The guide members (see reference numeral 400 in FIG. 7A) include a first guide member (see reference numeral 410 in FIG. 7A) and a second guide member (see reference numeral 420 in FIG. 7A).

The display apparatus 10 in the first operation mode will be described with reference to FIG. 1. The first housing 310 and the second housing 320 are coupled to each other. The first display part 110 may be exposed to the outside and provide (e.g., display) first image information IM1 to a user. The second display part 120 and the third display part 130 are accommodated (e.g., positioned) in the first housing 310 and the second housing 320, respectively.

The display apparatus 10 in the second operation mode will be described with reference to FIG. 2. The first housing 310 and the second housing 320 are separated (e.g., moved in opposite directions away) from each other. The first housing 310 may move in a first direction DR1, and the second housing 320 may move in a fourth direction DR4. As the first housing 310 and the second housing 320 are separated from each other, the second display part 120 and the third display part 130 are externally exposed from the first housing 310 and the second housing 320, respectively. In the second operation mode, the first to third display parts 110, 120, and 130 are exposed to the outside to respectively provide (e.g., display) the first to third image information IM1, IM2, and IM3 to a user.

The first display part 110 is exposed to the outside in the first and second operation modes. The second display part 120 is accommodated (e.g., positioned) in the first housing 310 in the first operation mode and exposed from the first housing 310 to the outside in the second operation mode. The third display part 130 is accommodated (e.g., positioned) in the second housing 320 in the first operation mode and exposed from the second housing 320 to the outside in the second operation mode.

In the second operation mode, the first display part 110 may have an area that is about 0.8 times to about 1.2 times the sum of the areas of the second display part 120 and the third display part 130. Here, an area of the flexible display module 100 exposed in the second operation mode is about 2 times that of the flexible display module 100 exposed in the first operation mode. That is, as the first operation mode is changed to the second operation mode, the display apparatus 10 may provide image information that is twice as big to a user.

As illustrated in FIGS. 3A and 3B, the display apparatus 10 may be folded. FIG. 3A illustrates the display apparatus 10 folding in the first operation mode. FIG. 3B illustrates the display apparatus 10 folding in the second operation mode.

The first display part 110 may have a display surface that is divided (e.g., organized or arranged) into a first part 111 and a second part 112 on a plane with respect to the hinge 230. The display apparatus 10 may be in-folded so that the first part 111 and the second part 112 face each other. The portability of the display apparatus 10 may be further increased through such folding. Also, when the display apparatus 10 is capable of in-folding, the display surface may be protected from external impacts or contaminants to increase durability of the display apparatus 10.

FIGS. 4A and 4B are perspective views of a supporting member of the display apparatus 10, according to some example embodiments of the present invention. FIG. 4A is a perspective view illustrating a shape of a supporting member 200 when the display apparatus (see reference numeral 10 in FIG. 1) is not folded.

FIG. 4B is a perspective view illustrating a shape of the supporting member 200 when the display apparatus (see reference numeral 10 in FIG. 3A) is folded.

The supporting member 200 includes a first supporting part 210, a second supporting part 220, and a hinge 230. The supporting member 200 is coupled to the first display part (see reference numeral 110 in FIG. 3A) of the flexible display module (see reference numeral 100 in FIG. 3A). Thus, when the supporting member 200 is foldable relative to the hinge, the flexible display module (see reference numeral 100 in FIG. 3A) is also foldable relative to the hinge.

The first supporting part 210 for supporting a lower portion of the first part (see reference numeral 111 in FIG. 3A) may have a flat plate shape. The second supporting part 220 for supporting a lower portion of the second part (see reference numeral 112 in FIG. 3A) may have a flat plate shape.

The second supporting part 220 may be spaced a distance (e.g., a predetermined distance) from the first supporting part 210. Also, the contact interface of the first supporting part 210 and the second supporting part 220 may have a curved shape. The curved shape allows the first and second supporting parts 210 and 220 to flexibly move without interfering with each other in a folding process of the supporting member 200. Embodiments of the present invention, however, are not limited to the contact interface of the first supporting part 210 and the second supporting 220 having a curved shape.

The hinge 230 connects the first supporting part 210 to the second supporting part 220. Also, the hinge 230 allows the first and second supporting parts 210 and 220 to each rotate with respect to a direction axis parallel to a second direction DR2.

According to some embodiments, the supporting member 200 is hard enough to support the flexible display module (see reference numeral 100 in FIG. 2).

Referring to FIG. 4C, the supporting member 200 may further include a battery 240 and a heat radiation plate 250. When the supporting member 200 includes the battery 240, the thickness and hardness of the supporting member 200 may be increased to support the flexible display module (see reference numeral 100 in FIG. 2) better. The heat radiation plate 250 reduces the heat from the display apparatus (see reference numeral 10 in FIG. 2). The heat radiation plate 250 may include various metals having high thermal conductivity, such as copper and aluminum to rapidly discharge heat.

The shapes of the first and second supporting parts 210 and 220 are not limited thereto and may be shapes capable of supporting a portion or all of the flexible display module 100. The shape of the hinge 230 is not limited thereto and may be a structure arranged between the first and second supporting parts 210 and 220 to allow each of the first and second supporting parts 210 and 220 to rotate.

FIG. 5 is a perspective view of a housing and a guide member of the display apparatus 10, according to some example embodiments of the present invention. FIG. 6 is a perspective view of the guide member according to some example embodiments of the present invention.

As illustrated in FIG. 5, a first guide member 410 is coupled to the first housing 310, and a second guide member 420 is coupled to the second housing 320.

Referring to FIG. 5, a space (e.g., a predetermined space) may be defined in each of the first and second housings 310 and 320, and the flexible display module (see reference numeral 100 in FIG. 2) and the supporting member (see reference numeral 200 in FIG. 2) may be accommodated (e.g., positioned) in inner spaces of the first and second housings 310 and 320. The first supporting part 210 may be inserted into or withdrawn from the first housing 310. The second supporting part 220 may be inserted into or withdrawn from the second housing 320.

A display module guide groove GD may be defined in each of the first and second housings 310 and 320. The flexible display module (see reference numeral 100 in FIG. 2) may be arranged in the display module guide groove GD. The display module guide groove GD may maintain the flexible display module (see reference numeral 100 in FIG. 2) in a flat state.

The display module guide groove GD guides a moving position of the flexible display module (see reference numeral 100 in FIG. 2). While the operation mode is changed between the first operation mode and the second operation mode, the second and third display parts 120 and 130 of the flexible display module (see reference numeral 100 in FIG. 2) are guided by the display module guide groove GD in the first and second housings 310 and 320, respectively.

A supporting member guide groove GS may be defined in each of the first and second housings 310 and 320. The supporting member (see reference numeral 200 in FIG. 2) may be arranged in the supporting member guide groove GS.

The supporting member guide groove GS guides a moving position of the supporting member (see reference numeral 200 in FIG. 2). While the operation mode is changed between the first operation mode and the second operation mode, the first and second supporting parts 210 and 220 are guided by the supporting member guide groove GS in the first and second housings 310 and 320.

The first and second housings 310 and 320 protect the flexible display module (see reference numeral 100 in FIG. 2) from external impacts and pollutants.

However, the shapes of the first and second housings 310 and 320 are not limited thereto, and if an inner space for accommodating the flexible display module (see reference numeral 100 in FIG. 2) and the supporting member (see reference numeral 200 in FIG. 2) exists and a portion for guiding the flexible display module (see reference numeral 100 in FIG. 2) and the supporting member (see reference numeral 200 in FIG. 2) is defined, the shapes of the first and second housings 310 and 320 may be different from those illustrated in FIG. 5.

The first guide member 410 is coupled to the first housing 310 to guide the flexible display module (see reference numeral 100 in FIG. 2). The first guide member 410 may contact the second display part (see reference numeral 120 in FIG. 2). A surface at which the first guide member 410 contacts the second display part (see reference numeral 120 in FIG. 2) may have a curved shape. This is because the curved shape may relieve stress applied to the second display part (see reference numeral 120 in FIG. 2) when the operation mode changes between the first operation mode and the second operation mode.

The first guide member 410 may be a rotational body. Here, the first guide member 410 rotates (e.g., about a central axis of the first guide member 410) to allow the second display part (see reference numeral 120 in FIG. 2) to move along the display module guide groove GD.

The second guide member 420 is coupled to the second housing 320 to guide the flexible display module (see reference numeral 100 in FIG. 2). The second guide member 420 may contact the third display part (see reference numeral 130 in FIG. 2). A surface at which the second guide member 420 contacts the third display part (see reference numeral 130 in FIG. 2) may have a curved shape. This is because the curved shape may relieve stress applied to the third display part (see reference numeral 130 in FIG. 2) when the operation mode changes between the first operation mode and the second operation mode.

The second guide member 420 may be a rotational body. Here, the second guide member 420 rotates to allow the third display part (see reference numeral 130 in FIG. 2) to move along the display module guide groove GD.

The shapes of the first and second guide members are not limited thereto and may be any shape that helps to guide the flexible display module (see reference numeral 100 in FIG. 2).

FIGS. 7A to 9 are cross-sectional views of a display apparatus according to some example embodiments of the present invention. FIGS. 7A and 7B illustrate cross-sections of the display apparatus 10 in the first and the second operation modes. FIG. 8 illustrates a cross-section of a display apparatus 10-1 in which a first housing 310-1 and a second housing 320-1 rolls a portion of the flexible display module 100 to accommodate the portion of the flexible display module 100. FIG. 9 illustrates a cross-section of a display apparatus 10-2 that further includes a lower protection member 500 for protecting a lower portion of the flexible display module 100.

Referring to FIGS. 7A and 7B, the first housing 310 and the second housing 320 may be arranged at the outmost portion of the display apparatus 10.

In the first operation mode illustrated in FIG. 7A, the first housing 310 and the second housing 320 are coupled to each other. In the second operation mode illustrated in FIG. 7B, the first housing 310 moves in the first direction DR1, and the second housing 320 moves in the fourth direction DR4 so that the first housing 310 and the second housing 320 are separated from each other.

Referring to FIG. 7A, in the first operation mode, the first supporting part 210 is inserted into the first housing 310, and the second supporting part 220 is inserted into the second housing 320.

Referring to FIGS. 7A and 7B, when the first supporting part 210 is inserted into the first housing 310, the first guide member 410 guides the second display part 120 to be inserted into the first housing 310. When the first supporting part 210 starts to be inserted into the first housing 310, the first guide member 410 transfers one end of the second display part 120 in the first direction DR1 and bends the end at about 180°. Thereafter, one end of the second display part 120, which is bent at about 180°, is horizontally transferred in the fourth direction DR4. Accordingly, the first display part 110 and the second display part 120 face each other'in the first operation mode.

When the second supporting part 220 is inserted into the second housing 320, the second guide member 420 guides the third display part 130 to be inserted into the second housing 320. When the second supporting part 220 starts to be inserted into the second housing 320, the second guide member 420 transfers one end of the third display part 130 in the fourth direction DR4 and bends the end at about 180°. Thereafter, one end of the third display part 130, which is bent at about 180°, is horizontally transferred in the first direction DR1. Accordingly, the first display part 110 and the third display part 130 face each other in the first operation mode.

Referring to FIG. 7B, in the second operation mode, the first supporting part 210 is withdrawn from the first housing 310, and the second supporting part 220 is withdrawn from the second housing 320.

When the first supporting part 210 is withdrawn from the first housing 310, the first guide member 410 guides the second display part 120 to be withdrawn from the first housing 310. When the first supporting part 210 is completely withdrawn from the first housing 310, the first display part 110 and the second display part 120 may be on the same plane.

When the first supporting part 210 is completely withdrawn from the first housing 310, the first housing 310 may further include an additional fixing unit to prevent the first supporting part 210 or the second display part 120 from being completely separated from the first housing 310.

When the second supporting part 220 is withdrawn from the second housing 320, the second guide member 420 guides the third display part 130 to be withdrawn from the second housing 320. When the second supporting part 220 is completely withdrawn from the second housing 320, the first display part 110 and the third display part 130 may be on the same plane. When the second supporting part 220 is completely withdrawn from the second housing 320, the second housing 320 may further include an additional fixing unit to prevent the second supporting part 220 or the third display part 130 from being completely separated from the second housing 320.

Referring to FIG. 8, in the first operation mode, a first housing 310-1 and a second housing 320-1 accommodate a portion of the flexible display module 100, which is rolled around a first guide member 410-1 and a second guide member 420-1. In the first operation mode, the second display part 120 is rolled around the first guide member 410-1, and the third display part 130 is rolled around the second guide member 420-1.

The first guide member 410-1 rolls the second display part 120 that is inserted into the first housing 310-1 around the first guide member 410-1. Also, the second guide member 420-1 rolls the third display part 130 that is inserted into the second housing 320-1 around the second guide member 420-1. Here, to easily roll the flexible display module 100, the first guide member 410-1 and the second guide member 420-1 may have a cylindrical shape, although embodiments of the present invention are not limited thereto.

Referring to FIG. 9, a display apparatus 10-2 including a lower protection member 500 is arranged or positioned under the flexible display module 100. The lower protection member 500 is provided to protect a lower portion of the flexible display module 100 against stress caused by external impacts, repeated rolling, or sliding. The lower protection member 500 may be divided into a first lower protection member 510 and a second lower protection member 520.

The first lower protection member 510 may be arranged or positioned under the first display part 110 and may include metal. Thus, the first lower protection member 510 may have a hard property so as not to bend. Because the first display part 110 is not curved or bent in the first and second operation modes, the first display part 110 may be protected by the protection member having a hard property.

The second lower protection member 520 may be arranged or positioned under the second and third display parts 120 and 130 and may include a plastic film. Thus, the second lower protection member 520 may be easily curved or bent by an external force. Because the second display part 120 and the third display part 130 are curved or bent in the first operation mode, the second display part 120 may be protected by the second lower protection member having a soft property.

However, the positioning of the protection member 500 is not limited thereto, and the second lower protection member 520 instead of the first lower protection member 510 may be arranged or positioned under the first display part 110.

FIGS. 10A to 10C are perspective views of a housing and a guide member according to an embodiment of the inventive concept. FIGS. 10A to 10C illustrate a second housing 320-2 including an auxiliary supporting member 321 and an elastic member 322. A first housing including an auxiliary supporting member and an elastic member is not shown because the first housing is substantially the same as the second housing 320-2.

FIGS. 10A and 10B illustrate the second housing 320-2 in the second operation mode. In the second operation mode, an auxiliary supporting member 321 of the second housing 320-2 is arranged or positioned below the third display part (see reference numeral 130 in FIG. 2) to support the third display part (see reference numeral 130 in FIG. 2).

The elastic member 322 may be arranged or positioned under the auxiliary supporting member 321. In the second operation mode, the elastic member 322 pushes the auxiliary supporting member 321 up in a third direction DR3. Accordingly, the auxiliary supporting member 321 may support the third display part (see reference numeral 130 in FIG. 2).

The auxiliary supporting member 321 may have one end that is a curved surface SF having a predetermined curvature. When the second supporting part 220 moves in the fourth direction DR4 in a state in which the curved surface SF of the auxiliary supporting member 321 contacts the second supporting part 220, a force may be applied between the curved surface SF and the second supporting part 220. The auxiliary supporting member 321 may be moved toward a lower side of the second supporting part 220 by a force acting between the curved surface SF and the second supporting part 220.

FIG. 10C illustrates the second housing 320-2 in the first operation mode. In the first operation mode, the auxiliary supporting member 321 is arranged below the second supporting part 220.

Referring to FIG. 7B, a separating space may be generated between the flexible display module 100 and the housings 310 and 320 in the second operation mode, and as illustrated in FIGS. 10A to 10C, the separating space may be compensated for when the auxiliary supporting member 321 and the elastic member 322 are used.
