[0054] In the following description, embodiments will be illustrated in more detail with reference to the accompanying drawings, in which the same reference numerals throughout denote the same elements. However, this disclosure may be implemented in a variety of different forms and should not be construed as being limited to the embodiments shown herein. These embodiments are provided precisely as examples so that this disclosure will be thorough and complete, and will fully convey the aspects and features of this disclosure to those skilled in the art. Therefore, processes, elements, and techniques that are not essential for those skilled in the art to fully understand the aspects and features of this disclosure may not be described. Unless otherwise stated, the same reference numerals denote the same elements throughout all drawings and the entire written description, and therefore redundant descriptions of the same elements may not be repeated.

[0055] When a particular implementation can be carried out differently, the specific process sequence may differ from the described sequence. For example, two consecutively described processes may be performed simultaneously or substantially simultaneously, or they may be performed in the reverse order of the described sequence.

[0056] In the accompanying drawings, for clarity, the relative dimensions, thicknesses, and proportions of elements, layers, and regions may be exaggerated and / or simplified. For ease of illustration, spatial relative terms such as “below,” “under,” “lower,” “below,” “above,” “upper,” etc., may be used herein to describe the relationship of one element or feature as shown in the drawings to another element(s). It should be understood that, in addition to the orientation shown in the drawings, spatial relative terms are intended to also include different orientations of the device in use or operation. For example, if the device in the figures is flipped, an element described as below, under, or beneath other elements or features will be oriented above those elements or features. Thus, the exemplary terms “below” and “below” can encompass both above and below orientations. The device may be oriented in other ways (e.g., rotated 90 degrees or in other orientations), and the spatial relative descriptive terms used herein should be interpreted accordingly.

[0057] In the accompanying figures, the DR1, DR2, and DR3 axes are not limited to the three axes of a Cartesian coordinate system and can be interpreted in a broader sense. For example, the DR1, DR2, and DR3 axes can be perpendicular to each other or substantially perpendicular to each other, or they can represent different directions that are not perpendicular to each other.

[0058] It should be understood that although the terms “first,” “second,” “third,” etc., may be used herein to describe various elements, components, regions, layers, and / or sections, these elements, components, regions, layers, and / or sections should not be limited by these terms. These terms are used to distinguish one element, component, region, layer, or section from another element, component, region, layer, or section. Therefore, without departing from the spirit and scope of this disclosure, the first element, first component, first region, first layer, or first section described below may be referred to as a second element, second component, second region, second layer, or second section.

[0059] It should be understood that when an element or layer is referred to as being on, connected to, or coupled to another element or layer, it can be directly on, directly connected to, or directly coupled to another element or layer, or there may be one or more intermediate elements or layers. Similarly, when a layer, area, or element is referred to as being “electrically connected” to another layer, area, or element, it can be directly electrically connected to the other layer, area, or element, and / or can be indirectly electrically connected in the presence of one or more intermediate layers, areas, or elements. Furthermore, it should be understood that when an element or layer is referred to as being between two elements or layers, it can be the only element or layer between the two elements or layers, or there may be one or more intervening elements or layers.

[0060] The terminology used herein is for the purpose of describing particular embodiments and is not intended to limit the invention. Unless the context clearly indicates otherwise, the singular forms “a” and “an” as used herein are intended to include the plural forms as well. It will be further understood that the terms “comprises,” “comprising,” “includes,” “including,” “has,” “have,” and “having,” when used in this specification, specify the presence of the stated feature, integral, step, operation, element, and / or component, but do not preclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or groups thereof. As used herein, the term “and / or” includes any and all combinations of one or more of the associated listed items. For example, the expression “A and / or B” means A, B, or A and B. When an expression such as “at least one of…” follows a list of elements, it modifies the entire list of elements and does not modify individual elements in the list. For example, the expressions “at least one of a, b, and c” and “at least one selected from the group consisting of a, b, and c” mean only a, only b, only c, both a and b, both a and c, both b and c, all of a, b, and c, or variations thereof.

[0061] As used herein, the terms “substantially,” “about,” and similar terms are used as approximations rather than terms of degree, and are intended to allow for inherent deviations in measured or calculated values ​​that will be recognized by those skilled in the art. Furthermore, when describing embodiments of this disclosure, the use of “may” means “one or more embodiments of this disclosure.” As used herein, the terms “use,” “using,” and “used” may be considered synonymous with the terms “utilize,” “utilizing,” and “utilized,” respectively.

[0062] Unless otherwise defined, all terms used herein (including technical and scientific terms) shall have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It should also be understood that terms, such as those defined in common dictionaries, shall be interpreted as having the meaning consistent with their meaning in the relevant technical and / or specification context, and shall not be interpreted in an idealized or overly formal sense, unless expressly so defined herein.

[0063] Figure 1 This is a perspective view of a display device according to an embodiment of the present disclosure. Figure 2 It shows Figure 1 The folded state of the display device is shown in the image.

[0064] Reference Figure 1 The display device DD according to embodiments of the present disclosure may have a quadrilateral shape having a long side extending in a first direction DR1 and a short side extending in a second direction DR2 intersecting the first direction DR1. However, it is not limited thereto, and the display device DD may have various suitable shapes such as a circular shape or other polygonal shapes. The display device DD may be a flexible display device.

[0065] In the following text, the direction perpendicular to or substantially perpendicular to the plane defined by the first direction DR1 and the second direction DR2 is defined as the third direction DR3. Furthermore, as used herein, the expressions "when viewed in a plane" and "in a plan view" can be defined as the state of being viewed in the third direction DR3.

[0066] The display device DD may include a folded region FA and multiple non-folded regions NFA1 and NFA2. The non-folded regions NFA1 and NFA2 may include a first non-folded region NFA1 and a second non-folded region NFA2. The folded region FA may be disposed between the first non-folded region NFA1 and the second non-folded region NFA2. The first non-folded region NFA1, the folded region FA, and the second non-folded region NFA2 may be arranged along a first direction DR1.

[0067] As an example, a folded region FA and two non-folded regions NFA1 and NFA2 are shown, but the number of folded regions FA and non-folded regions NFA1 and NFA2 is not limited to this. For example, a display device DD may include more than two non-folded regions and multiple folded regions disposed between the non-folded regions.

[0068] The upper surface of the display device DD can be defined as the display surface DS, and the display surface DS can have a plane defined by a first direction DR1 and a second direction DR2. The image IM generated in the display device DD can be provided to the user through the display surface DS.

[0069] The display surface DS may include a display area DA and a non-display area NDA surrounding the display area DA (e.g., near the periphery of the display area DA). The display area DA may display an image, while the non-display area NDA may not display an image. The non-display area NDA may surround the display area DA (e.g., near the periphery of the display area DA) and may define an edge of the display device DD printed with an appropriate color (e.g., a predetermined color).

[0070] The display device DD may include at least one sensor SN and at least one camera CA. The sensor SN and camera CA may be located adjacent to the edge of the display device DD. The sensor SN and camera CA may be configured in the display area DA to be adjacent to the non-display area NDA. The sensor SN and camera CA may be located in a second non-folding area NFA2, but this disclosure is not limited thereto, and the sensor SN and camera CA may also be located in a first non-folding area NFA1.

[0071] Light can be transmitted through a portion of the display device DD that houses a sensor SN and a camera CA, and can be supplied to the camera CA and sensor SN. For example, the sensor SN could be a proximity illuminance sensor, but the type of sensor SN is not limited to this. The camera CA can capture external images. Multiple sensor SNs and camera CAs can be configured.

[0072] Reference Figure 2 The display device DD can be a foldable display device DD that can be folded or unfolded. For example, the display device DD can be folded when the folding region FA is bent based on the folding axis FX, which is parallel to or substantially parallel to the second direction DR2. The folding axis FX can be defined as a major axis that is parallel to or substantially parallel to the long side of the display device DD. However, it is not limited to this; the folding axis FX can be defined as a minor axis that is parallel to or substantially parallel to the short side of the display device DD, and the display device DD can be folded about the folding axis FX that is parallel to or substantially parallel to the short side of the display device DD.

[0073] When the display device DD is folded, the first non-folded region NFA1 and the second non-folded region NFA2 can face each other, and the display device DD can be folded inward so that the display surface DS is not exposed to the outside. However, this disclosure is not limited thereto. For example, the display device DD can be folded outward around the folding axis FX, so that the display surface DS is exposed to the outside.

[0074] The distance between the first non-folded region NFA1 and the second non-folded region NFA2 can be less than the diameter of the circle defined by the radius of curvature R of the folded region FA. In this case, the folded region FA can be folded into a dumbbell shape, and the distance between the first non-folded region NFA1 and the second non-folded region NFA2 can be made shorter (e.g., reduced).

[0076] Reference Figure 3 The display device DD may include a display module DM (e.g., a display or touch display), a camera CA, a sensor SN, an electronic module (e.g., an electronic device or electronic circuit) EM, a power module (e.g., a power supply or power circuit) PSM, and a housing CAS.

[0077] The display module DM can include a window (WIN) and a display panel (DP). As an example, in... Figure 3 The diagram shows the window (WIN) and display panel (DP) in the stacked structure of the display module (DM). However, in addition to the window (WIN) and display panel (DP), the display module (DM) may also include various other components. The detailed stacked structure of the display module (DM) will be described in more detail below.

[0078] The WIN window can provide the front surface of the display device DD. The WIN window can transmit the image generated by the display panel DP and provide that image to the user.

[0079] The display panel DP may include displays corresponding to the display device DD (e.g., see...). Figure 1 The display area DA and the non-display area NDA are defined as follows. As used herein, the expression "area / part corresponds to another area / part" may mean that the area / part overlaps with the other area / part, and may not be limited to having the same area.

[0080] A first transmission region TA1 and a second transmission region TA2 can be defined within a display panel DP. The first transmission region TA1 and the second transmission region TA2 can have higher light transmittance than the transmission regions surrounding them. A camera CA can be positioned below the first transmission region TA1, and a sensor SN can be positioned below the second transmission region TA2. Light passing through the first transmission region TA1 and the second transmission region TA2 can be provided to the camera CA and the sensor SN.

[0081] The display module DM may include a data driver DDV disposed on the non-display area NDA of the display panel DP. The data driver DDV may be manufactured in the form of an integrated circuit chip and may be mounted on the non-display area NDA. However, it is not limited to this; the data driver DDV may be mounted on a flexible circuit board connected to the display panel DP.

[0082] The electronic module (EM) and power module (PSM) can be positioned below the display panel (DP). The EM and PSM can be connected to each other via separate flexible circuit boards. The EM controls the operation of the display module (DM). The PSM supplies power to the EM.

[0083] The housing CAS can accommodate the display module DM, the electronic module EM, and the power module PSM. The housing CAS may include two housings, such as a first housing CAS1 and a second housing CAS2, to fold the display module DM. The first housing CAS1 and the second housing CAS2 may extend in a second direction DR2 and may be arranged along a first direction DR1.

[0084] The display device DD may also include a hinge structure to connect the first housing CAS1 and the second housing CAS2 to each other, and to rotate the first housing CAS1 and the second housing CAS2 so that the display device DD is folded. The housing CAS can protect the display module DM, the electronic module EM, and the power module PSM.

The electronic module EM may be electrically connected to the power module PSM.

[0087] The control module 10 can control the overall operation of the display device DD. For example, the control module 10 can activate or deactivate the display module DM based on user input. The control module 10 can also control the image input module 30, the sound input module 40, the sound output module 50, etc., based on user input. The control module 10 may include at least one microprocessor.

[0088] The wireless communication module 20 can send / receive wireless signals to / from other terminals using Bluetooth or Wi-Fi lines. The wireless communication module 20 can also send / receive voice signals using general communication lines. The wireless communication module 20 may include: a transmitting circuit 22 that modulates the signal to be transmitted and transmits the modulated signal; and a receiving circuit 24 that demodulates the received signal.

[0089] The image input module 30 processes image signals to convert them into image data that can be displayed on the display module DM. The sound input module 40 receives external sound signals via a microphone in recording mode, voice recognition mode, etc., and converts them into electronic voice data. The sound output module 50 converts sound data received from the wireless communication module 20 or sound data stored in the memory 60, and outputs the converted sound data to the outside.

[0090] The external interface module 70 can be used as an interface to connect to an external charger, wired / wireless data port, card slot (e.g., slot for memory card, SIM / UIM card), etc.

[0091] The Power Supply Module (PSM) can provide power for the overall operation of the display device DD. The PSM may include general-purpose battery devices (e.g., batteries).

[0092] An electro-optical module (ELM) can be an electronic component that outputs or receives optical signals. The ELM can transmit or receive optical signals through a portion of a display module (DM). In this embodiment, the ELM may include a camera module (CAM) and a sensor module (SNM). The camera module (CAM) may include... Figure 3 The camera CA shown is illustrated. The sensor module SNM may include... Figure 3 The sensor SN shown is shown.

[0093] Figure 5 It shows including Figure 3 The cross-sectional view of the electronic panel of the display panel shown. Figure 6 It shows Figure 5 The cross-sectional view of the display panel shown.

[0094] As an example, Figure 5 and Figure 6 This is a cross-sectional view viewed in the first direction DR1.

[0095] Reference Figure 5 The electronic panel EP may include a display panel DP, an input sensing unit (e.g., an input sensing layer or panel) ISP disposed on the display panel DP, and an anti-reflective layer RPL disposed on the input sensing unit ISP. The display module DM described above may include the electronic panel EP.

[0096] The display panel DP can be a flexible display panel. The display panel DP according to embodiments of this disclosure can be a light-emitting display panel, but this disclosure is not particularly limited thereto. For example, the display panel DP can be an organic light-emitting display panel or an inorganic light-emitting display panel. The light-emitting layer of an organic light-emitting display panel can include organic light-emitting materials. The light-emitting layer of an inorganic light-emitting display panel can include quantum dots, quantum rods, etc. Hereinafter, for convenience, the display panel DP will be described in more detail in the case of an organic light-emitting display panel.

[0097] The input sensing unit (ISP) may include multiple sensors for sensing external inputs capacitively. When manufacturing the display device (DD), the ISP may be directly fabricated on the display panel (DP). However, it is not limited to this; the ISP may be fabricated as a panel independent of the display panel (DP) and then attached to the display panel (DP) via an adhesive layer.

[0098] When manufacturing a display device (DD), the anti-reflective layer (RPL) can be directly fabricated on the input sensing unit (ISP). However, it is not limited to this; the anti-reflective layer (RPL) can be fabricated as a separate panel and then attached to the input sensing unit (ISP) via an adhesive layer.

[0099] An anti-reflective layer (RPL) can be defined as an external light reflection prevention film. An RPL reduces the reflectivity of external light incident from above the display device (DD) towards the display panel (DP).

[0100] Reference Figure 6 The display panel DP may include a substrate SUB, a circuit element layer DP-CL disposed on the substrate SUB, a display element layer DP-OLED disposed on the circuit element layer DP-CL, and a thin film encapsulation layer TFE disposed on the display element layer DP-OLED.

The substrate SUB may include glass or a flexible plastic material (such as polyimide (PI)). The display element layer DP-OLED may be disposed on the display area DA.

[0102] Multiple pixels can be disposed in the circuit element layer DP-CL and the display element layer DP-OLED.

[0106] The display panel DP may include a first region AA1, a second region AA2, and a curved region BA between the first region AA1 and the second region AA2. The curved region BA may extend in a second direction DR2, and the first region AA1, the curved region BA, and the second region AA2 may be arranged along a first direction DR1.

[0107] The first region AA1 may include a display region DA and a non-display region NDA surrounding the display region DA (e.g., near the periphery of the display region DA). The non-display region NDA may surround the display region DA (e.g., near the periphery of the display region DA). The display region DA may display an image, and the non-display region NDA may not display an image. The second region AA2 and the curved region BA may not display an image.

[0108] When viewed from a third party onto DR3, the first region AA1 may include a first non-folded region NFA1, a second non-folded region NFA2, and a folded region FA between the first non-folded region NFA1 and the second non-folded region NFA2.

Emitting lines EL1 to ELm can extend in the second direction DR2 to connect to the emitting driver EDV.

[0113] The power line PL can extend in the first direction DR1 to be positioned in the non-display area NDA. The power line PL can be positioned between the display area DA and the light-emitting driver EDV. The power line PL can extend through the bending area BA to the second area AA2. When viewed in a plane (e.g., in a plan view), the power line PL can extend towards the lower end of the second area AA2. The power line PL can receive a drive voltage.

[0114] The connecting line CNL can extend along the second direction DR2 and is arranged along the first direction DR1. The connecting line CNL can be connected to the power line PL and the pixel PX. A driving voltage can be applied to the pixel PX through the power line PL and the connecting line CNL connected to each other.

[0115] The first control line CSL1 can be connected to the scan driver SDV and can extend through the curved area BA toward the lower end of the second area AA2. The second control line CSL2 can be connected to the light emission driver EDV and can extend through the curved area BA toward the lower end of the second area AA2.

[0118] A printed circuit board (PCB) can be connected to pads (PDs), and a timing controller and voltage generator can be mounted on the PCB. The timing controller can be manufactured as an integrated circuit chip and can be mounted on the PCB. The timing controller and voltage generator can be connected to the pads (PDs) via the PCB.

[0121] The scan driver SDV can generate multiple scan signals in response to scan control signals. Scan signals can be applied to pixels PX via scan lines SL1 to SLm. Scan signals can be applied sequentially to scan lines SL1 to SLm.

[0122] The data driver DDV can generate multiple data voltages corresponding to the image signal in response to a data control signal. These data voltages can be applied to pixel PX via data lines DL1 to DLn. The light-emitting driver EDV can generate multiple light-emitting signals in response to a light-emitting control signal. These light-emitting signals can be applied to pixel PX via light-emitting lines EL1 to ELm.

[0123] A pixel (PX) can receive a data voltage in response to a scan signal. A pixel (PX) can display an image by emitting light with a brightness corresponding to the data voltage in response to a light emission signal. The emission time of a pixel (PX) can be controlled by the light emission signal.

[0124] Figure 8 It shows the relationship with Figure 7 The image shows a cross-sectional view of the electronic panel corresponding to one pixel.

[0129] The semiconductor pattern may be doped with N-type or P-type dopant. The semiconductor pattern may include heavily doped regions and lightly doped regions. The conductivity of the heavily doped regions may be greater than that of the lightly doped regions, and the heavily doped regions may be used, or substantially used, as the source and drain electrodes of the transistor TR. The lightly doped regions may correspond to, or substantially correspond to, the active portion (e.g., the channel) of the transistor.

[0130] The source S, active portion A, and drain D of transistor TR can be formed from a semiconductor pattern. A first insulating layer INS1 can be disposed on the semiconductor pattern.

[0132] The connecting electrode CNE may include a first connecting electrode CNE1 and a second connecting electrode CNE2 to connect the transistor TR and the light-emitting element OLED to each other. The first connecting electrode CNE1 may be disposed on the third insulating layer INS3 and connected to the drain electrode D through a first contact hole CH1 defined in the first insulating layer INS1 to the third insulating layer INS3 (e.g., penetrating the first insulating layer INS1 to the third insulating layer INS3).

[0137] The luminescent layer (EML) can be disposed on the hole control layer (HCL). The EML can be disposed in the region corresponding to the opening (PX_OP). The EML can include organic and / or inorganic materials. The EML can produce any of the following: red, green, and blue light.

[0138] An electron control layer (ECL) can be disposed on the light-emitting layer (EML) and the hole control layer (HCL). The ECL may include an electron transport layer and / or an electron injection layer. The HCL and the ECL can be disposed together in the light-emitting region (PA) and the non-light-emitting region (NPA).

[0139] The second electrode CE can be disposed on the electronic control layer ECL. The second electrode CE can be disposed in multiple pixels PX. The layer containing the light-emitting element OLED can be defined as the display element layer DP-OLED.

[0140] The thin-film encapsulation layer TFE can be disposed on the second electrode CE and cover the pixel PX. The thin-film encapsulation layer TFE may include a first encapsulation layer EN1 disposed on the second electrode CE, a second encapsulation layer EN2 disposed on the first encapsulation layer EN1, and a third encapsulation layer EN3 disposed on the second encapsulation layer EN2.

[0141] The first encapsulation layer EN1 and the third encapsulation layer EN3 may include inorganic insulating layers and can protect the pixel PX from moisture / oxygen. The second encapsulation layer EN2 may include organic insulating layers and can protect the pixel PX from impurities such as dust particles.

[0142] A first voltage can be applied to the first electrode AE ​​via transistor TR, and a second voltage having a lower level than the first voltage can be applied to the second electrode CE. Holes and electrons injected into the light-emitting layer EML can recombine with each other to form excitons, and the light-emitting element OLED can emit light when the excitons transition to the ground state.

[0143] The layer from the substrate (SUB) to the thin-film encapsulation layer (TFE) can be defined as the display panel (DP). The input sensing unit (ISP) can be disposed on the thin-film encapsulation layer (TFE). The input sensing unit (ISP) can be directly fabricated on the upper surface of the thin-film encapsulation layer (TFE).

[0144] The base layer BS can be disposed on the thin-film encapsulation layer TFE. The base layer BS may include an inorganic insulating layer. At least one inorganic insulating layer can be provided on the thin-film encapsulation layer TFE as the base layer BS.

[0145] The input sensing unit (ISP) may include a first conductive pattern CTL1 and a second conductive pattern CTL2 disposed on the first conductive pattern CTL1. The first conductive pattern CTL1 may be disposed on a base layer BS. An insulating layer TINS ​​may be disposed on the base layer BS to cover the first conductive pattern CTL1. The insulating layer TINS ​​may include an inorganic insulating layer or an organic insulating layer. The second conductive pattern CTL2 may be disposed on the insulating layer TINS.

[0146] The first conductive pattern CTL1 and the second conductive pattern CTL2 may overlap with the non-light-emitting region NPA. The first conductive pattern CTL1 and the second conductive pattern CTL2 may be disposed on the non-light-emitting region NPA between (e.g., adjacent to each other) light-emitting regions PA, and may have a mesh shape.

[0147] The first conductive pattern CTL1 and the second conductive pattern CTL2 can form the sensor of the input sensing unit ISP described above. For example, the mesh-shaped first conductive pattern CTL1 and the second conductive pattern CTL2 can be spaced apart (e.g., separated) in an appropriate area (e.g., a predetermined area) to form the sensor. A portion of the second conductive pattern CTL2 can be connected to the first conductive pattern CTL1.

[0148] An anti-reflective layer RPL can be disposed on a second conductive pattern CTL2. The anti-reflective layer RPL may include a black matrix BM and multiple color filters CF. The black matrix BM may overlap with the non-emitting region NPA, and the color filters CF may overlap with the emitting region PA.

[0149] A black matrix BM can be disposed on an insulating layer TINS ​​to cover a second conductive pattern CTL2. An opening B_OP, overlapping the light-emitting region PA and the opening PX_OP, can be confined within the black matrix BM (e.g., it can penetrate the black matrix B). The black matrix BM can block light by absorbing it. The width of the opening B_OP can be greater than the width of the opening PX_OP.

[0150] Color filters (CFs) can be placed on the insulating layer (TINS) and the black matrix (BM). Color filters (CFs) can also be placed in the opening (B_OP). Planarized insulating layer (PINS) can be placed on the color filters (CFs). Planarized insulating layer (PINS) can provide a flat or substantially flat top surface.

[0151] When external light traveling towards the display panel DP is reflected by the mirror-like display panel DP and returned to the external user, the user may visually perceive the external light. To prevent or reduce this phenomenon, for example, the anti-reflective layer RPL may include a color filter CF that displays the same or substantially the same color as the light emitted by the pixels PX of the display panel DP. The color filter CF can filter the external light to the same or substantially the same color as the light emitted by the pixels PX. In this case, the external light may be invisible to the user.

[0152] However, this disclosure is not limited thereto, and the antireflective layer RPL may include a polarizing film to reduce the reflectivity of external light. The polarizing film may be fabricated separately from the input sensing unit ISP and attached to the input sensing unit ISP via an adhesive layer. The polarizing film may include a retarder and / or a polarizer.

[0153] Figure 9 It is along Figure 7 The sectional view shown is taken by line I-I'.

[0154] As an example, Figure 9 A cross section of the display module DM corresponding to line I-I' and a cross section of the component disposed below (e.g., below) the display module DM are shown.

[0155] Reference Figure 9 The display device DD may include a display module (e.g., a monitor or touch display) DM, a digitizer DGT, a shielding layer SHL, a heat dissipation layer RHL, and an insulating layer INS. The display module DM may include a hard coating HC, a printed layer PIT, a window WIN, a window protection layer WP, a shock absorbing layer ISL, an electronic panel EP, and a panel protection layer PPL. The display device DD may include a first adhesive layer AL1 to a seventh adhesive layer AL7 for bonding the components described above to each other.

[0156] The display module DM can be a flexible display module. The display module DM may include a first non-folding region NFA1, a folding region FA, and a second non-folding region NFA2. The display module DM can be folded when the folding region FA is folded around the folding axis FX described above.

[0157] The window (WIN) can be disposed on the shock-absorbing layer (ISL). The window (WIN) can protect the electronic panel (EP) from external scratches. The window (WIN) can be optically transparent. The window (WIN) can include glass. However, it is not limited to this; the window (WIN) can include a synthetic resin film.

[0158] A window WIN can have a multi-layered or single-layered structure. For example, a window WIN may include multiple synthetic resin films bonded together with an adhesive, or it may include a glass substrate and a synthetic resin film bonded together with an adhesive.

[0159] A window protective layer WP can be applied to the window WIN. The window protective layer WP can include flexible plastic materials such as polyimide or polyethylene terephthalate. A hard coating HC can be applied to the upper surface of the window protective layer WP.

[0160] The printed layer PIT can be applied to the lower surface of the window protector WP. The printed layer PIT can be black, but its color is not limited to black. The printed layer PIT can be adjacent to the edge of the window protector WP.

[0161] An impact absorbing layer (ISL) can be applied to an electronic panel (EP). The ISL protects the electronic panel (EP) by absorbing external impacts applied from above the display device (DD) towards the EP. The ISL can be manufactured in the form of a stretchable film.

[0162] The impact-absorbing layer (ISL) can include flexible plastic materials. Flexible plastic materials can be defined as synthetic resin films. For example, the impact-absorbing layer (ISL) can include flexible plastic materials such as polyimide (PI) or polyethylene terephthalate (PET).

[0163] The panel protective layer PPL can be disposed below the electronic panel EP. The panel protective layer PPL can be disposed below the display panel DP. The panel protective layer PPL protects the lower portion of the display panel DP. The panel protective layer PPL can include a flexible plastic material. For example, the panel protective layer PPL can include polyethylene terephthalate (PET).

[0164] The first adhesive layer AL1 can be disposed between the window protective layer WP and the window WIN. The window protective layer WP and the window WIN can be bonded to each other through the first adhesive layer AL1. The first adhesive layer AL1 can cover the printed layer PIT.

[0165] The second adhesive layer AL2 can be disposed between the window WIN and the shock-absorbing layer ISL. The window WIN and the shock-absorbing layer ISL can be bonded to each other through the second adhesive layer AL2.

[0166] The third adhesive layer AL3 can be disposed between the shock-absorbing layer ISL and the electronic panel EP. The shock-absorbing layer ISL and the electronic panel EP can be bonded to each other through the third adhesive layer AL3.

[0167] The fourth adhesive layer AL4 can be disposed between the electronic panel EP and the panel protective layer PPL. The electronic panel EP and the panel protective layer PPL can be bonded to each other through the fourth adhesive layer AL4. The fifth adhesive layer AL5 can be disposed below the panel protective layer PPL.

[0168] The support plate (PLT) can be positioned below and support the display module (DM). The support plate (PLT) can be made of non-metallic materials. For example, the support plate (PLT) can include fiber-reinforced composite materials. Fiber-reinforced composite materials can be carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFRP).

[0169] The support plate PLT can be made lightweight by including fiber-reinforced composite materials. By including fiber-reinforced composite materials, the support plate PLT according to embodiments of the present disclosure can have a lighter weight than a metal support plate including metallic materials, and can have modulus and strength values ​​similar to those of a metal support plate.

[0170] Because the support plate PLT incorporates fiber-reinforced composite materials, its shape can be processed more easily than that of a metal support plate. For example, a support plate PLT incorporating fiber-reinforced composite materials can be more readily processed using laser technology or microblasting.

[0171] Multiple opening POPs can be defined in the portion of the support plate PLT that overlaps with the folded area FA. The opening POPs can be formed as portions extending through the support plate PLT in the third direction DR3. The opening POPs can be formed using the aforementioned laser processing or micro-spraying process.

[0172] The support plate PLT may include a first support plate PLT1, a second support plate PLT2, and a folded portion PLT_F. For example, the boundary between the first support plate PLT1, the second support plate PLT2, and the folded portion PLT_F is shown as a dashed line in the support plate PLT.

[0173] The folding portion PLT_F can be positioned between the first support plate PLT1 and the second support plate PLT2. The first support plate PLT1, the folding portion PLT_F, and the second support plate PLT2 can be positioned along a first direction DR1. The opening POP can be confined within the folding portion PLT_F.

[0174] In the following text, as used herein, the term "overlap" is defined as a state in which portions of components overlap each other when viewed on a plane (e.g., in a plan view) in a display device DD set to a flat or substantially flat state.

[0175] The first support plate PLT1 can be positioned below and overlap with the first non-folded region NFA1. The second support plate PLT2 can be positioned below and overlap with the second non-folded region NFA2. The folded portion PLT_F can be positioned below and overlap with the folded region FA.

[0176] The folded portion PLT_F may include a curved surface portion CSP, a first extension portion EX1, a second extension portion EX2, a first reverse bending portion ICV1, and a second reverse bending portion ICV2. As an example, the boundaries of the curved surface portion CSP, the first extension portion EX1, the second extension portion EX2, the first reverse bending portion ICV1, and the second reverse bending portion ICV2 are shown in dashed lines in the support plate PLT, and for convenience, their reference numerals are shown above the display module DM by extending the dashed boundary lines upwards.

[0177] The curved surface portion CSP, the first extension portion EX1, the second extension portion EX2, the first reverse curved portion ICV1, and the second reverse curved portion ICV2 can be arranged along the first direction DR1. As an example, the curved surface portion CSP can be disposed in the central portion of the folded portion PLT_F. The first reverse curved portion ICV1 can be defined as a portion of the folded portion PLT_F adjacent to the first support plate PLT1. The second reverse curved portion ICV2 can be defined as a portion of the folded portion PLT_F adjacent to the second support plate PLT2.

[0178] A curved surface portion CSP can be disposed between the first extension portion EX1 and the second extension portion EX2. An opening POP can be defined within the curved surface portion CSP. When the folded portion PLT_F is folded, the curved surface portion CSP can be bent to have a desired curvature (e.g., a predetermined curvature). Since the opening POP is defined within the curved surface portion CSP, the flexibility of the curved surface portion CSP can be increased. As a result, the curved surface portion CSP can be easily folded.

[0179] The first extension portion EX1 can be disposed between the first reverse bending portion ICV1 and the bending surface portion CSP. The second extension portion EX2 can be disposed between the second reverse bending portion ICV2 and the bending surface portion CSP.

[0180] The first reverse bending portion ICV1 can be disposed between the first support plate PLT1 and the bending surface portion CSP. More specifically, the first reverse bending portion ICV1 can be disposed between the first support plate PLT1 and the first extension portion EX1. The second reverse bending portion ICV2 can be disposed between the second support plate PLT2 and the bending surface portion CSP. More specifically, the second reverse bending portion ICV2 can be disposed between the second support plate PLT2 and the second extension portion EX2.

[0181] The cover layer COV can be disposed below the support plate PLT. The cover layer COV can cover the opening POP defined in the support plate PLT from below (e.g., below). The cover layer COV can overlap with the curved surface portion CSP of the folded portion PLT_F. The cover layer COV can contact the lower surface of the curved surface portion CSP in which the opening POP is formed.

[0182] The cover layer COV can have a lower elastic modulus than the support plate PLT. For example, the cover layer COV can include thermoplastic polyurethane or rubber, but the material of the cover layer COV is not limited to these. The cover layer COV can be manufactured in the form of a functional sheet and attached to the support plate PLT.

[0183] The digitizer DGT can be positioned below the support plate PLT. The cover layer COV can be positioned between the support plate PLT and the digitizer DGT. The cover layer COV can be separated from the upper surface of the digitizer DGT.

[0184] The digitizer DGT can receive position information indicated by the user on the display surface DS. The digitizer DGT can be implemented using electromagnetic methods (e.g., electromagnetic resonance). For example, the digitizer DGT may include a digitizer sensor substrate containing multiple coils. However, it is not limited to this; the digitizer DGT can also be implemented using active electrostatic methods.

[0185] When a user moves the pen on the display device DD, an alternating current signal drives the pen to generate a vibrating magnetic field, which induces a signal in a coil. The pen's position can be detected by the signal induced in the coil. The digitizer DGT determines the pen's position by detecting the electromagnetic changes caused by the pen's proximity.

[0186] When the support plate PLT located on and adjacent to the digitizer DGT is made of metal, the sensitivity of the digitizer DGT may be reduced due to the metal (e.g., it may be reduced). For example, the digitizer DGT may malfunction when the signal transmitted on the display device DD is blocked by signal interference from the metal support plate.

[0187] However, in the embodiments of this disclosure, the digitizer DGT can function normally because the support plate PLT disposed on the digitizer DGT is made of non-metallic fiber-reinforced composite material.

[0188] The digitizer DGT can be separated into two below (e.g., below) the folded portion PLT_F. The digitizer DGT may include a first digitizer DGT1 and a second digitizer DGT2 that are spaced apart from each other (e.g., separated) and arranged along a first direction DR1. The first digitizer DGT1 may be located below the first support plate PLT1, and the second digitizer DGT2 may be located below the second support plate PLT2.

[0189] The first digitizer DGT1 and the second digitizer DGT2, which are separated from each other (e.g., isolated), can be connected to the digitizer driver via a flexible circuit board.

[0190] The first digitizer DGT1 may overlap with the portion of the first support plate PLT1 and the folded portion PLT_F adjacent to the first support plate PLT1. For example, the first digitizer DGT1 may overlap with the portion of the first reverse bending portion ICV1, the first extension portion EX1, and the portion of the bending surface portion CSP adjacent to the first extension portion EX1.

[0191] The second digitizer DGT2 may overlap with the portion of the second support plate PLT2 and the folded portion PLT_F adjacent to the second support plate PLT2. For example, the second digitizer DGT2 may overlap with the portion of the second reverse bending portion ICV2, the second extension portion EX2, and the portion of the bending surface portion CSP adjacent to the second extension portion EX2.

[0192] A shielding layer SHL may be disposed below the digitizer DGT. The shielding layer SHL may comprise a metal. More specifically, the shielding layer SHL may comprise magnetic metal powder. The shielding layer SHL can shield against electromagnetic interference that may be applied to the digitizer DGT from below (e.g., from below) the display device DD. The shielding layer SHL can be defined as an electromagnetic shielding layer.

[0193] The shielding layer SHL can contact the lower surface of the digitizer DGT. The shielding layer SHL can be directly attached to the lower surface of the digitizer DGT without the use of an adhesive layer. The shielding layer SHL can be manufactured in film form and can be directly attached to the lower surface of the digitizer DGT via a thermoforming process.

[0194] When viewed in a plane (e.g., in a plan view), the first opening OP1, adjacent to the first support plate PLT1 and overlapping with the folded portion PLT_F, can be defined in the shielding layer SHL. The first opening OP1 can overlap with the first reverse bending portion ICV1.

[0195] When viewed in a plane (e.g., in a plan view), the second opening OP2, adjacent to the second support plate PLT2 and overlapping with the folded portion PLT_F, can be defined within the shielding layer SHL. The second opening OP2 can overlap with the second reverse bending portion ICV2.

[0196] Similar to the digitizer DGT, the shielding layer SHL can be separated into two below (e.g., below) the folded portion PLT_F. The shielding layer SHL may include a first shielding layer SHL1 and a second shielding layer SHL2 that are spaced apart from each other (e.g., separated) and arranged along a first direction DR1.

[0197] The first shielding layer SHL1 can be disposed below the first digitizer DGT1 and can contact the lower surface of the first digitizer DGT1. The first opening OP1 can be confined within the first shielding layer SHL1. The second shielding layer SHL2 can be disposed below the second digitizer DGT2 and can contact the lower surface of the second digitizer DGT2. The second opening OP2 can be confined within the second shielding layer SHL2.

[0221] Figure 10A It is along Figure 7 The sectional view shown is taken from line II-II'. Figure 10B It shows Figure 10A The bending state of the bending region shown.

[0222] Reference Figure 10AThe panel protective layer PPL and the fourth adhesive layer AL4 may not be disposed below the bending region BA. The panel protective layer PPL and the fourth adhesive layer AL4 may be disposed below the second region AA2 of the electronic panel EP. The data driver DDV (e.g., shown as an integrated circuit D-IC) may be disposed on the second region AA2 of the electronic panel EP.

[0223] The display device DD may also include a bend protection layer BAP. The bend protection layer BAP may be disposed on the bend region BA, the portion of the first region AA1 adjacent to the bend region BA, and the portion of the second region AA2 adjacent to the bend region BA. The bend protection layer BAP may extend continuously from the portion of the first region AA1 adjacent to the bend region BA to the portion of the second region AA2 adjacent to the bend region BA.

[0224] The bend protector layer BAP may be spaced apart from the third adhesive layer AL3. The bend protector layer BAP may be spaced apart from the data driver DDV in the second region AA2. The bend protector layer BAP may comprise an acrylic-based resin or a urethane-based resin.

[0225] The heat dissipation layer RHL and the insulation layer INS can be located below the portion of the adjacent bending area BA of the digitizer DGT, and the shielding layer SHL may not be located below the portion of the adjacent bending area BA of the digitizer DGT.

[0226] The display device DD may also include a spacer SPC disposed below the insulating layer INS. The thickness of the spacer SPC may be greater than the combined thickness of the seventh adhesive layer AL7, the heat dissipation layer RHL, and the insulating layer INS. The spacer SPC may be double-sided tape. For example, the spacer SPC may include a base layer containing a flexible material (e.g., polyethylene terephthalate) and adhesives disposed on the upper and lower surfaces of the base layer.

[0227] The display device DD may further include a first insulating strip TAP1 and a second insulating strip TAP2, which are disposed below the digitizer DGT between the spacer SPC and the side of the digitizer DGT adjacent to the curved region BA. The first insulating strip TAP1 and the second insulating strip TAP2 may include insulating material.

[0228] The first insulating tape TAP1 can be disposed below the digitizer DGT and attached to the lower surface of the digitizer DGT. The second insulating tape TAP2 can be disposed below the first insulating tape TAP1 and attached to the lower surface of the first insulating tape TAP1. The thickness of the first insulating tape TAP1 can be greater than the thickness of the second insulating tape TAP2. The width of the first insulating tape TAP1 can be greater than the width of the second insulating tape TAP2.

[0229] Reference Figure 10B The curved region BA can be bent to have an appropriate curvature (e.g., a predetermined curvature). When the curved region BA is bent, the second region AA2 can be positioned below (e.g., under) the first region AA1. Therefore, the data driver DDV (e.g., shown as an integrated circuit D-IC) can be positioned below (e.g., under) the first region AA1.

[0230] The display device DD may also include an insulating tape ITP disposed below the second region AA2 and covering the data driver DDV. The insulating tape ITP may be disposed below the portion of the bending protective layer BAP disposed below the second region AA2.

[0233] Figure 11 yes Figure 9 A perspective view of the support plate shown. Figure 12 yes Figure 11 The enlarged plan view of region AA shown.

[0234] Reference Figure 11 and Figure 12 The support plate PLT may include a first support plate PLT1 arranged along the first direction DR1, a folded portion PLT_F, and a second support plate PLT2. The folded portion PLT_F may include a first reverse bending portion ICV1, a first extension portion EX1, a bent surface portion CSP, a second extension portion EX2, and a second reverse bending portion ICV2 arranged along the first direction DR1.

[0235] A grid pattern can be defined in the curved surface portion CSP. For example, the opening POPs defined in the curved surface portion CSP can be arranged according to appropriate rules (e.g., predetermined rules). The opening POPs can be arranged in a grid shape to form the grid pattern of the curved surface portion CSP.

[0236] The first hole H1 and the second hole H2 can be defined within the second support plate PLT2 (e.g., they can penetrate the second support plate PLT2). The first hole H1 and the second hole H2 can be adjacent to the edge of the second support plate PLT2. The camera CA and the sensor SN described above can be respectively disposed in the first hole H1 and the second hole H2.

[0237] The opening POP can extend longer in the second direction DR2 than in the first direction DR1. The opening POP can include a plurality of first sub-openings SOP1 arranged along the second direction DR2 and a plurality of second sub-openings SOP2 adjacent to the first sub-openings SOP1 in the first direction DR1 and arranged along the second direction DR2. The first sub-openings SOP1 can be arranged to stagger with the second sub-openings SOP2.

[0238] Figure 13 yes Figure 9 The diagram shows a plan view of the shielding layer.

[0239] As an example, in Figure 13 In the diagram, the areas of the curved surface portion CSP, the first extension portion EX1 and the second extension portion EX2, as well as the first reverse bending portion ICV1 and the second reverse bending portion ICV2 are shown in dashed lines.

[0240] Reference Figure 13 The first opening OP1 may be defined in the central portion of the first curved surface portion CS1 in the first direction DR1, and extend in the second direction DR2. The second opening OP2 may be defined in the central portion of the second curved surface portion CS2 in the first direction DR1, and extend in the second direction DR2.

[0241] The first opening OP1 can open the first shielding layer SHL1 in the second direction DR2 to separate the first shielding layer SHL1. For example, the first opening OP1 can open the first curved surface portion CS1 in the second direction DR2 to separate the first curved surface portion CS1.

[0242] The second opening OP2 can open the second shielding layer SHL2 in the second direction DR2 to separate the second shielding layer SHL2. For example, the second opening OP2 can open the second curved surface portion CS2 in the second direction DR2 to separate the second curved surface portion CS2.

[0243] Figure 14 It shows Figure 9 The folded state of the display device is shown in the image.

[0244] For convenience, Figure 14In the diagram, the display module DM is shown as a single layer. Furthermore, for ease of illustration, the support plate PLT, digitizer DGT, and shielding layer SHL are shown together with the display module DM, while other components are omitted.

[0245] For example, the boundaries of the first support plate PLT1 and the second support plate PLT2, the curved surface portion CSP, the first extension portion EX1 and the second extension portion EX2, and the first reverse curved portion ICV1 and the second reverse curved portion ICV2 are shown in dashed lines in the support plate PLT. Furthermore, as an example, the boundaries of the first flat portion PP1 and the second flat portion PP2, the first flat extension portion PXP1 and the second flat extension portion PXP2, and the first curved surface portion CS1 and the second curved surface portion CS2 are shown in dashed lines in the shielding layer SHL.

[0246] Reference Figure 14 The support plate PLT can be folded around the folding axis FX. The support plate PLT can be folded into a dumbbell shape. When the support plate PLT is folded, the display module DM can be folded together with the support plate PLT.

[0247] When the folding portion PLT_F is folded around the folding axis FX, the support plate PLT can be folded. When the folding portion PLT_F is folded, the curved surface portion CSP can be bent to have a desired curvature (e.g., a predetermined curvature). For example, the folding area FA of the display module DM on the curved surface portion CSP can be bent to have a radius of curvature R. For example, the radius of curvature R can be approximately 1.53 mm.

[0248] The first reverse bending portion ICV1 can be bent in a direction opposite to the bending direction of the bending surface portion CSP. The second reverse bending portion ICV2 can be bent in a direction opposite to the bending direction of the bending surface portion CSP. The second reverse bending portion ICV2 can have a shape that is symmetrical or substantially symmetrical to the shape of the first reverse bending portion ICV1.

[0249] When the folded portion PLT_F is folded, the first support plate PLT1 and the second support plate PLT2 can remain flat or substantially flat. Therefore, the first non-folded region NFA1 and the second non-folded region NFA2 can be kept flat or substantially flat by the first support plate PLT1 and the second support plate PLT2.

[0250] When the folded portion PLT_F is folded, the distance GP between the first support plate PLT1 and the second support plate PLT2 in the first direction DR1 can be less than the diameter of a circle with a radius of curvature R. Therefore, the support plate PLT can be folded into a dumbbell shape.

[0251] The first extension EX1 can remain flat or substantially flat between the curved surface portion CSP and the first reverse curved portion ICV1. The first extension EX1 can extend from the first reverse curved portion ICV1 toward the curved surface portion CSP in a flat or substantially flat state.

[0252] The second extension EX2 can remain flat or substantially flat between the curved surface portion CSP and the second reverse curved portion ICV2. The second extension EX2 can extend from the second reverse curved portion ICV2 toward the curved surface portion CSP in a flat or substantially flat state.

[0253] When the folding portion PLT_F is folded, the first flat portion PP1 and the second flat portion PP2 can remain flat or substantially flat together with the first support plate PLT1 and the second support plate PLT2. The portion of the first digitizer DGT1 between the first flat portion PP1 and the first support plate PLT1, and the portion of the second digitizer DGT2 between the second flat portion PP2 and the second support plate PLT2, can also remain flat or substantially flat.

[0254] When the folded portion PLT_F is folded, the first curved surface portion CS1 can be bent together with the first reverse curved portion ICV1. The first curved surface portion CS1 can be bent into a shape corresponding to the first reverse curved portion ICV1. The portion of the first digitizer DGT1 that overlaps with the first curved surface portion CS1 and the first reverse curved portion ICV1 can be bent together with the first curved surface portion CS1 and the first reverse curved portion ICV1.

[0255] When the folded portion PLT_F is folded, the second curved surface portion CS2 can be bent together with the second reverse curved portion ICV2. The second curved surface portion CS2 can be bent into a shape corresponding to the second reverse curved portion ICV2. The portion of the second digitizer DGT2 that overlaps with the second curved surface portion CS2 and the second reverse curved portion ICV2 can be bent together with the second curved surface portion CS2 and the second reverse curved portion ICV2.

[0256] When the folded portion PLT_F is folded, the portion of the first flat extension PXP1 that overlaps with the first extension EX1 can maintain a flat or substantially flat shape together with the first extension EX1. When the folded portion PLT_F is folded, the portion of the second flat extension PXP2 that overlaps with the second extension EX2 can maintain a flat or substantially flat shape together with the second extension EX2.

[0257] Reference Figure 9 and Figure 14Because the sixth adhesive layer AL6 is not disposed on the curved surface portion CSP, the portions of the first digitizer DGT1 and the second digitizer DGT2 that overlap with the curved surface portion CSP do not need to bend together with the curved surface portion CSP. Furthermore, the portions of the first flat extension portion PXP1 and the second flat extension portion PXP2 that overlap with the curved surface portion CSP do not need to bend together with the curved surface portion CSP.

[0258] A first flat extension portion PXP1 can extend from a first curved surface portion CS1 in a flat state. A second flat extension portion PXP2 can extend from a second curved surface portion CS2 in a flat state. The first flat extension portion PXP1 can extend to form a first angle θ1 relative to a third direction DR3. The second flat extension portion PXP2 can extend to form a second angle θ2 relative to a third direction DR3. As an example, each of the first angle θ1 and the second angle θ2 can be approximately 8.92 degrees.

[0259] The central portion of the first curved surface portion CS1, which defines the first opening OP1, may overlap or substantially overlap with the portion of the first reverse curved portion ICV1 having the maximum curvature. In other words, the first opening OP1 may be defined to overlap with the portion of the first reverse curved portion ICV1 having the maximum curvature.

[0260] The central portion of the second curved surface portion CS2, which defines the second opening OP2, may overlap or substantially overlap with the portion of the second reverse curved portion ICV2 having the maximum curvature. In other words, the second opening OP2 may be defined to overlap with the portion of the second reverse curved portion ICV2 having the maximum curvature.

[0261] Because the first opening OP1 is defined to overlap with the first reverse bending portion ICV1, the first reverse bending portion ICV1 can be bent more easily. Because the second opening OP2 is defined to overlap with the second reverse bending portion ICV2, the second reverse bending portion ICV2 can be bent more easily.

[0262] Figure 15 The folded state of the comparative display device according to the comparative example or comparative implementation is shown.

[0263] As an example, Figure 15 It shows the relationship with Figure 14 The cross-section corresponding to the above reference will be discussed below. Figure 14 The components described will be further described in more detail. Figure 15 The structure shown.

[0264] Reference Figure 15In the SHL-C shielding layer of the comparison display device DD-C, the first opening OP1 and the second opening OP2 are not necessarily limited. Because the first opening OP1 and the second opening OP2 are not limited in the comparison display device DD-C, due to the SHL-C shielding layer... Figure 15 The first reverse bending portion ICV1 and the second reverse bending portion ICV2 shown can be bent to less than Figure 14 The bending of the first reverse bending portion ICV1 and the second reverse bending portion ICV2 shown in the figure.

[0265] In this case, the curved surface portion of the CSP may be more curved to have a greater curvature. Because the radius of curvature is inversely proportional to the curvature, Figure 15 The folded area FA of the display module DM on the curved surface portion of the CSP can be bent into a shape with a larger diameter than that of the CSP. Figure 14 The radius of curvature R shown is smaller than the radius of curvature R'. As an example, the radius of curvature R' could be approximately 1.49 mm. Furthermore, in... Figure 15 In this case, each of the first angle θ1 and the second angle θ2 can be approximately 8.28 degrees.

[0266] Reference Figure 14 and Figure 15 Stress can be proportional to curvature. As the curvature of the curved surface portion CSP increases, the display module DM is bent to have a greater curvature, and therefore, the stress on the display module DM on the curved surface portion CSP may also increase.

[0267] In some embodiments of this disclosure, because the first opening OP1 and the second opening OP2 are defined within the shielding layer SHL, the bending characteristics of the first reverse bending portion ICV1 and the second reverse bending portion ICV2 can be improved. With the improved bending characteristics of the first reverse bending portion ICV1 and the second reverse bending portion ICV2, the radius of curvature of the curved surface portion CSP can be increased. Therefore, the stress on the display module DM on the curved surface portion CSP can be reduced.

[0268] In some implementations, the support structure can support the support plate PLT, allowing the support plate PLT to maintain a dumbbell shape. See below for further details. Figure 22 and Figure 23 A schematic diagram of the supporting structure is described in more detail.

[0269] exist Figure 14 In the folded state shown, the support plate PLT maintains a dumbbell shape, but the support plate PLT can have a first repulsive force to return from the dumbbell shape to a "U" shape. Figure 15In the folded state shown, the support plate PLT maintains a dumbbell shape, but the support plate PLT can have a second repulsive force to return from the dumbbell shape to a "U" shape. When the second repulsive force is set to approximately 1.0, the first repulsive force can be reduced to approximately 0.95 compared to the second repulsive force. In other words, the first repulsive force can be reduced due to the first opening OP1 and the second opening OP2.

[0270] Figure 16 A folded state of a display device according to another embodiment of the present disclosure is shown.

[0271] As an example, Figure 16 It shows the relationship with Figure 14 The cross section corresponding to the above reference, and will be discussed in the following text. Figure 14 The components described are described in more detail. Figure 16 The configuration of the shielding layer SHL-1 of the display device DD-1 is shown in the figure.

[0272] Reference Figure 16 The first opening OP1-1 can be defined to overlap with the entire first reverse bending portion ICV1. The second opening OP2-1 can be defined to overlap with the entire second reverse bending portion ICV2. The bending characteristics of the first reverse bending portion ICV1 can be further improved by the first opening OP1-1. The bending characteristics of the second reverse bending portion ICV2 can be further improved by the second opening OP2-1.

[0273] Figure 17 This is a plan view of a shielding layer according to another embodiment of the present disclosure. Figure 18 It shows including Figure 17 The shielding layer shown is displayed in the folded state of the device.

[0274] As an example, Figure 17 It shows the relationship with Figure 13 The floor plan corresponding to the floor plan, and Figure 18 It shows the relationship with Figure 14 The cross-section corresponding to the above reference. In the following text, we will discuss the cross-section corresponding to the above reference. Figure 13 and Figure 14 The components described will be further described in more detail. Figure 17 and Figure 18 The configuration of the shielding layer SHL-2 and the display device DD-2 is shown in the figure.

[0275] Reference Figure 17 and Figure 18 Multiple first openings OP1-2 may be defined in a first curved extension CEP1 that overlaps with the folded portion PLT_F. Multiple second openings OP2-2 may be defined in a second curved extension CEP2 that overlaps with the folded portion PLT_F.

[0276] On a plane defined by a first direction DR1 and a second direction DR2 (e.g., in a plan view), a direction intersecting the first direction DR1 and the second direction DR2 can be defined as a first diagonal direction DDR1. On a plane defined by a first direction DR1 and a second direction DR2 (e.g., in a plan view), a direction intersecting the first diagonal direction DDR1 can be defined as a second diagonal direction DDR2.

[0277] The first opening OP1-2 can be arranged along the first diagonal direction DDR1 and the second diagonal direction DDR2. The second opening OP2-2 can be arranged along the first diagonal direction DDR1 and the second diagonal direction DDR2. The first opening OP1-2 and the second opening OP2-2 can extend longer in the second direction DR2 than in the first direction DR1.

[0278] When the display device DD-2 is folded, the folding area FA of the display module DM on the curved surface portion CSP can be bent to have a first radius of curvature R1. As an example, the first radius of curvature R1 can be approximately 1.51 mm. Furthermore, in Figure 18 In this case, each of the first angle θ1 and the second angle θ2 can be approximately 8.72 degrees.

[0279] Figures 19 to 21 This is a plan view of a shielding layer according to other embodiments of this disclosure.

[0280] As an example, Figures 19 to 21 Shown as with Figure 13 The floor plan corresponds to the floor plan above, and the following text will refer to the floor plan of the above reference. Figure 13 The components described will be further described in more detail. Figures 19 to 21 The configuration of shielding layers SHL-3, SHL-4 and SHL-5 is shown.

[0281] Reference Figure 19 Multiple first openings OP1-3 may be defined in a first curved extension portion CEP1, and multiple second openings OP2-3 may be defined in a second curved extension portion CEP2. The first openings OP1-3 may be arranged along a first diagonal direction DDR1 and a second diagonal direction DDR2. The second openings OP2-3 may be arranged along a first diagonal direction DDR1 and a second diagonal direction DDR2.

[0282] The first opening OP1-3 and the second opening OP2-3 can be circular. However, they are not limited to this; the first opening OP1-3 and the second opening OP2-3 can have various suitable shapes such as elliptical or polygonal.

[0283] Reference Figure 20 A plurality of first openings OP1-4 may be defined in a first curved extension portion CEP1, and a plurality of second openings OP2-4 may be defined in a second curved extension portion CEP2. The first openings OP1-4 may be arranged along a first direction DR1 and a second direction DR2. The second openings OP2-4 may be arranged along the first direction DR1 and the second direction DR2.

[0284] The first opening OP1-4 and the second opening OP2-4 can have a shape that is bent into a "C" shape. The rows can correspond to the first direction DR1. The first opening OP1-4 and the second opening OP2-4 in the h-th row and the first opening OP1-4 and the second opening OP2-4 in the (h+1)-th row can have a shape that is symmetrical or substantially symmetrical to each other in the second direction DR2, where h is a natural number greater than 0.

[0285] Reference Figure 21 Multiple first openings OP1-5 and OP1-6 may be defined in the first curved extension portion CEP1, and multiple second openings OP2-5 and OP2-6 may be defined in the second curved extension portion CEP2.

[0286] The first opening OP1-5 and the second opening OP2-5, defined in the first curved surface portion CS1 and the second curved surface portion CS2, can be formed to be larger than the first opening OP1-6 and the second opening OP2-6 defined in the first flat extension portion PXP1 and the second flat extension portion PXP2. Because the first opening OP1-5 and the second opening OP2-5 are formed to be larger, the bending characteristics of the first reverse curved portion ICV1 and the second reverse curved portion ICV2, which overlap with the first curved surface portion CS1 and the second curved surface portion CS2, respectively, can be improved.

[0287] Figure 22 A folded state of a display device according to another embodiment of the present disclosure is shown.

[0288] Figure 23 It shows Figure 22 The image shows the unfolded state of the display device.

[0289] Reference Figure 22 and Figure 23 The display device DD-3 may include a first support portion SUP1 and a second support portion SUP2, a first wing plate WPT1 and a second wing plate WPT2, and a folding support portion FSP. Figure 22 and Figure 23 The shielding layer SHL shown can be compared with the above reference. Figure 14 The shielding layers described are the same or substantially the same as SHL.

[0290] In the following text, we will assume Figure 23 The display device DD-3 shown is in an unfolded state. The stacking structure of the display device DD-3 can be described in more detail.

[0291] The first support portion SUP1 and the first wing plate WPT1 can be located below the first shielding layer SHL1. The second support portion SUP2 and the second wing plate WPT2 can be located below the second shielding layer SHL2.

[0292] The first support portion SUP1 can be located below the first flat portion PP1, and the second support portion SUP2 can be located below the second flat portion PP2. The first wing plate WPT1 can be located below the first curved extension portion CEP1, and the second wing plate WPT2 can be located below the second curved extension portion CEP2. The first wing plate WPT1 and the second wing plate WPT2 can be arranged along the first direction DR1.

[0293] The first wing plate WPT1 and the first support portion SUP1 may be connected to each other (e.g., joined or attached) to rotate relative to each other in a region adjacent to the boundary between the first support plate PLT1 and the folding portion PLT_F. The second wing plate WPT2 and the second support portion SUP2 may be connected to each other (e.g., joined or attached) to rotate relative to each other in a region adjacent to the boundary between the second support plate PLT2 and the folding portion PLT_F.

[0294] The folding support portion FSP can be disposed between the first wing WPT1 and the first curved extension CEP1, and between the second wing WPT2 and the second curved extension CEP2. The folding support portion FSP can be connected to the second wing WPT2 and extend onto the first wing WPT1. The folding support portion FSP can be connected to the second wing WPT2 via an adhesive layer AH. The folding support portion FSP may also not be connected to the first wing WPT1.

[0295] The folding support portion FSP can extend to the boundary between the first support plate PLT1 and the folding portion PLT_F, as well as the boundary between the second support plate PLT2 and the folding portion PLT_F.

[0296] When the display device DD-3 is folded, the folding support portion FSP can bend together with the folding portion PLT_F. When the folding support portion FSP bends, the first bending extension portion CEP1 and the second bending extension portion CEP2 provided on the folding support portion FSP can also bend. In addition, the first digitizer DGT1 and the second digitizer DGT2 respectively on the first bending extension portion CEP1 and the second bending extension portion CEP2 can also bend.

[0297] Because the folding support portion FSP is not connected to the first wing plate WPT1, when the display device DD-3 is folded and unfolded, the folding support portion FSP can move to slide in the space between the first wing plate WPT1 and the first curved extension portion CEP1. The folding support portion FSP can more stably support the folded state of the folding portion PLT_F.

[0298] When the folding support portion FSP is positioned below the folding portion PLT_F, the folding area FA of the display module DM on the curved surface portion CSP can be bent to have a second radius of curvature R2. As an example, the second radius of curvature R2 can be approximately 1.68 mm. Furthermore, in Figure 22 In this case, each of the first angle θ1 and the second angle θ2 can be approximately 9.68 degrees.

[0299] As an example, the settings have been described. Figure 14 The diagram shows the structure of the folded support portion FSP beneath the shielding layer SHL, but this disclosure is not limited thereto, and the folded support portion FSP can be disposed on the above reference. Figures 15 to 21 The shielding portion described is below SHL-C, SHL-1, SHL-2, SHL-3, SHL-4, and SHL-5.

[0300] As an example, refer to Figure 24 and Figure 25 For a more detailed description of the settings above, please refer to the reference. Figure 17 The description is in the shielding layer SHL-2 and above reference Figure 15 The configuration of the folded support portion FSP beneath the shielding layer SHL-C is described.

[0301] Figure 24 A folded state of a display device according to another embodiment of the present disclosure is shown.

[0302] As an example, Figure 24 It shows the relationship with Figure 22 The cross section corresponding to the above reference will be discussed below. Figure 22 The components described are described in more detail below. Figure 24 The configuration of the display device DD-4 shown is illustrated.

[0303] Reference Figure 24 The folding support section FSP can be set in Figure 17 and Figure 18 The diagram shows the shielding layer SHL-2, which is defined by the first opening OP1-2 and the second opening OP2-2. Other components of the display device DD-4 are as described above. Figure 22 The components of the described display device DD-3 are the same or substantially the same.

[0304] In this case, the folded area FA of the display module DM on the curved surface portion CSP can be bent to have a third radius of curvature R3. As an example, the third radius of curvature R3 can be approximately 1.65 mm. Furthermore, in Figure 24 In this case, each of the first angle θ1 and the second angle θ2 can be approximately 9.56 degrees.

[0305] Figure 25 A folded state of a display device according to another embodiment of the present disclosure is shown.

[0306] As an example, Figure 25 It shows the relationship with Figure 22 The cross section corresponding to the above reference will be discussed below. Figure 22 The components described are described in more detail below. Figure 25 The configuration of the display device DD-5 shown is illustrated.

[0307] Reference Figure 25 The folding support portion FSP can be positioned below the shielding layer SHL-C, which does not have the first opening OP1 and the second opening OP2. Other components of the display device DD-5 can be referenced above. Figure 22 The components of the described display device DD-4 are the same or substantially the same.

[0308] In this case, the folded area FA of the display module DM on the curved surface portion CSP can be bent to have a fourth radius of curvature R4. As an example, the fourth radius of curvature R4 can be approximately 1.61 mm. Furthermore, in... Figure 25 In this case, each of the first angle θ1 and the second angle θ2 can be approximately 9.02 degrees.

[0309] According to one or more embodiments of this disclosure, an opening may be defined in a shielding layer configured to contact the lower surface of the digitizer, and the opening may overlap with the reverse bending portion of a folded portion of a support plate used to support the display module. During the folding operation of the display device, the bending characteristics of the reverse bending portion can be improved due to the opening, and the radius of curvature of the bending surface portion of the folded portion can be increased. As a result, the stress on the display module on the bending surface portion can be reduced.
