In this specification, foldable may refer to a flexible state and may include a display device that is bendable, rollable, etc. In addition, foldable should be interpreted as any one of partially foldable and fully foldable and may mean that an element can be folded outward or folded inward.

[0043] The display device 1000 may include an inwardly foldable display device (i.e., a display device that can be folded inwardly) and an outwardly foldable display device (i.e., a display device that can be folded outwardly). For example, the display device 1000 may be a display device that can have an inwardly folded usage form and an outwardly folded usage form. Here, the inwardly folded usage form may mean a usage form in which the display areas DA are folded to face each other (refer to Figure 3 ). In addition, the outward folding use form may mean that the display area DA of the display device 1000 is folded so that the display area DA faces outward (so that Figure 3 The rear surface BA as the opposite surface of the front surface FFA faces each other) (reference Figure 5 ).

[0044] Hereinafter, for convenience of description, the inward-folding use form is referred to as a first use form, and the outward-folding use form is referred to as a second use form.

[0045] The display device 1000 may include Figure 2 The display module DP displays the image. Figure 2 The display module DP may include a display area DA displaying an image and a non-display area NDA at least partially surrounding the display area DA. The display area DA may display an image in a third direction DR3 through the front surface FFA of the display device 1000.

[0046] Figure 2The display module DP may include a first non-folding area NFA1, a second non-folding area NFA2, a first folding area FA1, and a second folding area FA2. The display device 1000 may be a foldable display device that can be alternately arranged into a first use form and a second use form. The first use form can be folded along the first folding area FA1. The second use form can be folded along the second folding area FA2. A detailed explanation of this will be provided later.

[0047] The first folding area FA1 and the second folding area FA2 may each extend mainly along the second direction DR2. Both the first folding area FA1 and the second folding area FA2 may be disposed between the first non-folding area NFA1 and the second non-folding area NFA2 and may be close to each other.

[0048] For example, the first folding area FA1 may be adjacent to the second non-folding area NFA2, and the second folding area FA2 may be adjacent to the first non-folding area NFA1 (when in the unfolded state). For example, the first folding area FA1 may be adjacent to the second non-folding area NFA2 in the first direction DR1, the second folding area FA2 may be adjacent to the first folding area FA1 in the first direction DR1, and the first non-folding area NFA1 may be adjacent to the second folding area FA2 in the first direction DR1 (in the unfolded state).

[0049] In an embodiment, the display device 1000 may further include cameras CM1 to CM3. In an embodiment, the display device 1000 may include a first camera CM1, a second camera CM2, and a third camera CM3. For example, the first camera CM1 may be an ultra-wide-angle camera, the second camera CM2 may be a wide-angle camera, and the third camera CM3 may be a telephoto camera. However, the present disclosure is not necessarily limited to the number and type of cameras CM1 to CM3 described herein.

[0050] In an embodiment, the display device 1000 may further include a camera auxiliary unit SCM for assisting imaging of the cameras CM1 to CM3. For example, the camera auxiliary unit SCM may be a light emitting diode (LED) lamp or a light sensor.

[0051] Figure 2 is along Figure 1 A cross-sectional view taken along line II'.

[0052] refer to Figure 1 and Figure 2 , the display device 1000 may include a first board MP1, a second board MP2, and a display module DP.

[0053] The display module DP may have a shape similar to that of the above-described display device 1000. The display module DP may include a display panel. An organic light emitting diode (OLED) display panel, a liquid crystal display (LCD) panel, a plasma display panel, an electrophoretic display panel, an electrowetting display panel, a quantum dot light emitting display panel, a micro LED display panel, a nano LED display panel, etc. may be applied as the display panel.

[0054] The display panel may include a flexible substrate including a flexible polymer material such as polyimide (PI). Accordingly, the display panel may be flexible, curved, folded or curled. The display panel may include a plurality of pixels. The plurality of pixels of the display panel may be located in a central portion of the display panel (e.g., a display area DA). In addition, the display panel may further include a signal line or a drive circuit for applying a signal to the pixel. At least a portion of the signal line and the drive circuit may be located outside the display panel (e.g., a non-display area NDA).

[0055] The pixel may include a light emitting layer and a circuit layer that controls the amount of light emitted from the light emitting layer. The circuit layer may include a plurality of lines, a plurality of electrodes, and at least one transistor. In an embodiment, the light emitting layer may include an organic light emitting material. The light emitting layer may be sealed by an encapsulation layer. The encapsulation layer may seal the light emitting layer and may prevent moisture, etc. from entering from the outside. The encapsulation layer may be a single-layer or multi-layer inorganic layer, but may be formed by a stacked layer in which an inorganic layer and an organic layer are alternately stacked.

[0056] A window protecting the display module DP may be further provided on the display module DP. The window may overlap the display panel in a thickness direction. In a plan view, the window may have substantially the same size as the display panel.

[0057] The window may be formed of glass, quartz, etc. The thickness of the window may be less than 100 μm. In some embodiments, the window may include ultra-thin chemically strengthened glass (ultra-thin glass (UTG)). In some embodiments, the window may include a flexible material.

[0058] The display device 1000 may further include a first board MP1 and a second board MP2 disposed under the display module DP.

[0059] The first plate MP1 and the second plate MP2 can prevent the display module DP from bending due to external force or can reduce the degree of bending (e.g., bending angle or curvature radius of bending). For example, even if an external force is applied, the first plate MP1 and the second plate MP2 can keep the display module DP in a relatively flat state.

[0060] The first plate MP1 and the second plate MP2 may include a rigid or semi-rigid material. For example, the first plate MP1 and the second plate MP2 may include a metal material such as stainless steel (SUS) or aluminum, or a polymer such as polymethyl methacrylate (PMMA), polycarbonate (PC), polyvinyl alcohol (PVA), acrylonitrile butadiene styrene (ABS), and polyethylene terephthalate (PET).

[0061] However, the portion PP of the first plate MP1 may be formed of another material. A detailed description of this will be provided later.

[0062] The second panel MP2 may be disposed on the first panel MP1. The display device 1000 may include a double-sided adhesive portion NAD1 bonded to the first panel MP1 and the second panel MP2. For example, the second panel MP2 may be bonded to the first panel MP1 through the double-sided adhesive portion NAD1.

[0063] For example, the double-sided adhesive portion NAD1 may be bonded to the first and second panels MP1 and MP2. For example, the double-sided adhesive portion NAD1 may be bonded to the first and second panels MP1 and MP2 in the first non-folding area NFA1, the second non-folding area NFA2, and the second folding area FA2.

[0064] The display device 1000 may further include a single-sided adhesive portion NAD2 adhered to the first panel MP1. For example, the single-sided adhesive portion NAD2 may be adhered to the first panel MP1 in the first folding area FA1.

[0065] The display module DP may be disposed on the second board MP2. The display device 1000 may include a double-sided adhesive portion NAD3 bonded to the second board MP2 and the display module DP. For example, the display module DP may be bonded to the second board MP2 through the double-sided adhesive portion NAD3.

[0066] Figure 3 It is shown Figure 1 a diagram showing a first form of use of the device, and Figure 4 It is shown Figure 2 A cross-sectional view of the changes in the first form of use.

[0067] refer to Figure 3 In the first usage form, the first non-folding area NFA1 and the second non-folding area NFA2 may be folded around the first folding area FA1 to face each other. For example, in the first usage form, the second non-folding area NFA2 may be folded in the third direction DR3. For example, in the first usage form, the back surface BA of the display device 1000 may cover at least a portion of the front surface FFA.

[0068] In the first use form, the first non-folding area NFA1 and the second non-folding area NFA2 may be folded around a first folding axis FX1 extending in the second direction DR2 to face each other.

[0069] In an embodiment, in the first usage form, a portion of the display area DA overlapping with the first non-folding area NFA1 may be exposed. For example, in the first usage form, the second non-folding area NFA2 may cover a portion of the first non-folding area NFA1. Accordingly, a portion of the display area DA may be exposed, and the exposed display area DA may be variously utilized by displaying an image.

[0070] In an embodiment, the cameras CM1, CM2, and CM3 may be exposed in the first usage form. For example, in the first usage form, the second non-folding area NFA2 may not cover the cameras CM1, CM2, and CM3. Accordingly, the cameras CM1, CM2, and CM3 may be exposed, and the exposed cameras CM1, CM2, and CM3 may be utilized. For example, an auxiliary camera for the first usage form may not be required separately.

[0071] refer to Figure 3 and Figure 4 , the display device 1000 may be folded around a first folding axis FX1 extending in a second direction DR2 so that the first non-folding area NFA1 and the second non-folding area NFA2 face each other. A first portion P1 of the second panel MP2 overlapping the first folding area FA1 may be bent, and thus the first non-folding area NFA1 and the second non-folding area NFA2 may face each other. The display module DP may be a flexible display module and thus may be easily bent.

[0072] The first plate MP1 may include a first portion and a second portion spaced apart from each other in an area overlapping the first folding area FA1. Because the first plate MP1 includes the first portion and the second portion spaced apart from each other, and the single-sided adhesive portion NAD2 is not adhered to the second plate MP2, the first non-folding area NFA1 and the second non-folding area NFA2 may be folded to face each other in the first use form.

[0073] Furthermore, in the first use form, the one-sided adhesive portion NAD2 can prevent the first portion P1 of the second plate MP2 from sagging in the third direction DR3 or a direction opposite to the third direction DR3.

[0074] Figure 5 It is shown Figure 1 a diagram of a second form of use of the display device, and Figure 6 It is shown Figure 2 A cross-sectional view of the change in the second usage form.

[0075] refer to Figure 5 In the second usage form, the first non-folding area NFA1 and the second non-folding area NFA2 may be folded around the second folding area FA2 to face away from each other. For example, in the second usage form, the second non-folding area NFA2 may be folded in a direction opposite to the third direction DR3. For example, in the second usage form, the rear surfaces of the display device 1000 may be folded to face each other so that the entire display area DA remains within the field of view.

[0076] In the second usage form, the first non-folding area NFA1 and the second non-folding area NFA2 may be folded away from each other around a second folding axis FX2 extending in the second direction DR2.

[0077] In an embodiment, in the second use form, the display area DA may be exposed. For example, in the second use form, the display area DA may be exposed in both the third direction DR3 and the direction opposite to the third direction DR3.

[0078] In an embodiment, the cameras CM1, CM2, and CM3 may be exposed in the second usage form. For example, an auxiliary camera for the second usage form may not be required separately.

[0079] refer to Figure 5 and Figure 6 In the display device 1000, the first non-folding area NFA1 and the second non-folding area NFA2 may be folded around a second folding axis FX2 extending in a second direction DR2 to face away from each other. A portion PP of the first panel MP1 overlapping the second folding area FA2 and a second portion P2 of the second panel MP2 overlapping the second folding area FA2 may be bent, and thus the first non-folding area NFA1 and the second non-folding area NFA2 may face away from each other. The display module DP may be a flexible display module and thus may be easily bent.

[0080] refer to Figures 3 to 6 Because the first and second folding axes FX1 and FX2 are different from each other, the width of the first direction DR1 of the display device 1000 in the first usage form crossing the second direction DR2 may be different from the width of the first direction DR1 of the display device 1000 in the second usage form.

[0081] The display device 1000 may divide the first folding axis FX1 and the second folding axis FX2 and thus may minimize wasted space, such as a space that overexposes the display area DA in the first usage form or a space that exposes the back surface BA in the second usage form.

[0082] Figure 7 is a diagram showing a first pattern, Figure 8 is a diagram showing a second pattern, and Fig. 9 It is shown Figure 1 A table of patterns or materials of the first plate and the second plate of the display device.

[0083] refer to Figure 7 , the first pattern PT1 may include openings OP arranged in a lattice shape. The openings OP may extend mainly in the second direction DR2 (i.e., their longest sides may extend in the second direction DR2). In addition, the openings OP may be arranged to cross each other. The plates MP1 and MP2 may be easily bent due to the openings OP. However, the present disclosure is not necessarily limited by the shape of the openings OP.

[0084] refer to Figure 8 , the second pattern PT2 may include patterns PT spaced apart from each other. For example, the second pattern PT2 may include a stripe pattern (eg, pattern PT). The board MP1 and the board MP2 may be easily compressed due to the patterns PT spaced apart from each other.

Accordingly, the first plate MP1 and the second plate MP2 may be easily bent in the first folding area FA1 and the second folding area FA2.

[0086] In the second case CASE2, the first portion P1 of the second plate MP2 may have the first pattern PT1, the second portion P2 of the second plate MP2 may have the first pattern PT1, and the portion PP of the first plate MP1 may have the second pattern PT2. Accordingly, the first plate MP1 and the second plate MP2 may be easily bent in the first folding area FA1 and the second folding area FA2.

[0087] In the third case CASE3, the first portion P1 of the second plate MP2 may have a first pattern PT1, the second portion P2 of the second plate MP2 may have a first pattern PT1, and the portion PP of the first plate MP1 may include a soft material SM. For example, the portion PP of the first plate MP1 may include a material having a low elastic modulus (such as an elastic modulus of less than 10 GPa, or preferably, an elastic modulus of less than 2 GPa). For example, the portion PP of the first plate MP1 may include polyurethane and / or silicon. Accordingly, the first plate MP1 and the second plate MP2 may be easily bent in the first folding area FA1 and the second folding area FA2.

[0088] The second portion P2 of the second plate MP2 may be stretched in the outwardly folded state. Figure 2 The third direction DR3 of the first plate MP1 is raised. Figure 2 The portion PP in the direction opposite to the third direction DR3 includes a soft material, so the second portion P2 of the second plate MP2 can be Figure 2 The third party droops in the opposite direction of DR3 and the rise can be compensated.

[0089] In the fourth case CASE4, the first portion P1 of the second plate MP2 may have the first pattern PT1, the second portion P2 of the second plate MP2 may have the second pattern PT2, and the portion PP of the first plate MP1 may have the first pattern PT1. Accordingly, the first plate MP1 and the second plate MP2 may be easily bent in the first folding area FA1 and the second folding area FA2.

[0090] In the fifth case CASE5, the first portion P1 of the second plate MP2 may have a first pattern PT1, the second portion P2 of the second plate MP2 may have a second pattern PT2, and the portion PP of the first plate MP1 may have a second pattern PT2. Accordingly, the first plate MP1 and the second plate MP2 may be easily bent in the first folding area FA1 and the second folding area FA2.

For example, the portion PP of the first plate MP1 may include a material having a low modulus. For example, the portion PP of the first plate MP1 may include at least one of polyurethane and silicon. Accordingly, the first plate MP1 and the second plate MP2 may be easily bent in the first folding area FA1 and the second folding area FA2.

[0092] The present disclosure may be applied to a display device and an electronic device including a display device. For example, the present disclosure may be applied to a digital television (TV), a three-dimensional (3D) TV, a mobile phone, a smart phone, a virtual reality (VR) / augmented reality (AR) device, a personal computer (PC) (such as a tablet computer or a notebook computer), a home electronic device, a personal digital assistant (PDA), a personal media player (PMP), a digital camera, a digital music player, a portable game console, a navigation system, etc.
