Detailed Implementation
[0045] By attaching Figure 1 The advantages, features, and methods of implementing the present invention can be clearly understood by referring to the detailed embodiments described below. However, the present invention is not limited to the embodiments disclosed below, but is implemented in various different forms. These embodiments are provided to fully disclose the invention and to fully inform those skilled in the art of its scope, which is defined only by the scope of the appended claims. Throughout the entire specification, the same reference numerals denote the same constituent elements.
[0046] Elements or layers referred to as "on" or "above" another element or layer include cases where they are directly on top of another element or where other layers or elements are disposed between them. On the other hand, elements referred to as "directly on" or "directly above" indicate that no other elements or layers are disposed between them. "And / or" includes each of the mentioned items individually and all combinations of more than one.
[0047] The spatially relative terms "below," "below," "lower," "above," and "upper," etc., may be used, as shown in the figures, to easily describe the relationship between one element or component and other elements or components. Spatially relative terms should be understood to include terms that include the directions shown in the figures plus the different directions of the elements during use or operation. Throughout the specification, the same reference numerals denote the same components.
[0048] Although terms such as "first," "second," etc., are used to describe various elements, constituent elements, and / or sections, these elements, constituent elements, and / or sections are not limited by these terms. These terms are used only to distinguish one element, constituent element, or section from other elements, constituent elements, or sections. Therefore, the first element, first constituent element, or first section mentioned below may also be a second element, second constituent element, or second section within the technical concept of this invention.
[0049] The embodiments described in this specification will be illustrated with reference to top and cross-sectional views, which are intended as schematic diagrams of the invention. Therefore, the form of the schematic diagrams may be varied due to manufacturing techniques and / or permissible errors. Thus, the embodiments of the invention are not limited to the specific forms illustrated, but also include variations in form resulting from manufacturing processes. Therefore, the areas illustrated in the drawings are schematic in nature, and the forms shown are intended to illustrate specific shapes of areas of elements, and are not intended to limit the scope of the invention.
[0050] Hereinafter, preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings.
[0051] Figure 1 This is a perspective view of an electronic device according to an embodiment of the present invention. Figure 2A and Figure 2B It is shown Figure 1 The diagram shows the folded state of the electronic device.
[0052] Reference Figure 1In embodiments of the present invention, the electronic device ED can be rectangular in shape, having a short side extending along a first direction DR1 and a long side extending along a second direction DR2 intersecting the first direction DR1. However, it is not limited to this; the electronic device ED can have various shapes such as circular and polygonal. The electronic device ED can be flexible.
[0053] Hereinafter, the direction that substantially intersects the plane defined by the first direction DR1 and the second direction DR2 is defined as the third direction DR3. Furthermore, in this specification, "when viewed on the plane" can be defined as the state of being viewed on the third direction DR3.
[0054] The electronic device ED 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 folded region FA, the first non-folded region NFA1, and the second non-folded region NFA2 may be arranged in a first direction DR1.
[0055] By way of example, although a folded region FA and two non-folded regions NFA1 and NFA2 are shown in the figure, the number of folded regions FA and non-folded regions NFA1 and NFA2 is not limited thereto. For example, an electronic device ED may include more than two non-folded regions and multiple folded regions arranged between the non-folded regions.
[0056] The upper surface of the electronic device ED can be defined by a display surface DS, which can have a plane defined by a first direction DR1 and a second direction DR2. The image IM generated in the electronic device ED can be provided to the user through the display surface DS.
[0057] The display surface DS may include a display area DA and a non-display area NDA surrounding 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 and define the border of the electronic device ED printed with specified colors.
[0058] Reference Figure 2A and Figure 2BThe electronic device ED can be a foldable (foldable) electronic device ED, either foldable or non-foldable. For example, the electronic device ED is folded by bending the folding region FA with reference to a folding axis FX parallel to the second direction DR2. The folding axis FX can be defined as a long axis parallel to the long side of the electronic device ED. When the electronic device ED is folded, the first non-folding region NFA1 and the second non-folding region NFA2 face each other, and the electronic device ED can be in-folded so that the display surface DS is not exposed to the outside. However, embodiments of the present invention are not limited thereto. For example, as Figure 2B As shown, the electronic device ED can be out-folded around the folding axis FX, so that the display surface DS is exposed to the outside. Furthermore, although not shown, the electronic device ED can also be folded inwards and outwards simultaneously.
[0059] Figure 3 yes Figure 1 An exploded perspective view of the electronic device shown.
[0060] Reference Figure 3 The electronic device ED may include: a display device DD, an electronic module EM, a power module PSM, and a housing EDC. Although not illustrated, the electronic device ED may also include a mechanism (e.g., a hinge) for controlling the folding action of the display device DD.
[0061] The display device DD can generate images and sense external input. The display device DD may include a window module WM and a display module DM. The window module WM provides the front surface of the electronic device ED. The window module WM can be configured on the display module DM and protect the display module DM. The window module WM allows light generated in the display module DM to be transmitted and provided to the user.
[0062] The display module DM may include a display panel DP. Although in Figure 3 The diagram only shows the display panel DP in the stacked structure of the display module DM, but in reality, the display module DM may also include multiple components disposed above and below the display panel DP. The detailed stacked structure of the display module DM will be described in detail below. The display panel DP may include components related to the electronic device ED. Figure 1 The display area DA and the non-display area NDA correspond to the display area DA and the non-display area NDA.
[0063] The display module DM may include a data driver unit DDV disposed on the non-display area NDA of the display panel DP. The data driver unit DDV may be directly fabricated as a circuit chip and mounted on the non-display area NDA. However, it is not limited to this; the data driver unit DDV may be mounted on a flexible circuit board connected to the display panel DP.
[0064] The electronic module EM and the power supply module PSM can be configured below the display device DD. Although not shown, the electronic module EM and the power supply module PSM can be connected to each other via an additional flexible circuit board. The electronic module EM can control the operation of the display device DD. The power supply module PSM can supply power to the electronic module EM.
[0065] The housing EDC can house the display device DD, the electronic module EM, and the power module PSM. The housing EDC can include two first housings EDC1 and a second housing EDC2 for folding the display device DD. The first housings EDC1 and the second housing EDC2 can extend in a second direction DR2 and be arranged in a first direction DR1.
[0066] Although not illustrated, the electronic device ED may also include a hinge structure for connecting the first housing EDC1 and the second housing EDC2. The housing EDC may be combined with the window module WM. The housing EDC can protect the display device DD, the electronic module EM, and the power module PSM.
[0067] Figure 4 This is a block diagram of an electronic device according to an embodiment of the present invention.
[0068] Reference Figure 4 The electronic device ED outputs various information through the display module 14 within the operating system. When the processor 11 runs the application program stored in the memory 12, the display module 14 provides the application information to the user through the display panel 14-1. Additionally, Figure 4 The display module 14 can refer to the aforementioned display module DM, and the display panel 14-1 refers to the aforementioned display panel DP.
[0069] The processor 11 acquires external input via the input module 13 or the sensor module 16-1 and runs the application corresponding to the external input. For example, if the user selects the camera icon displayed on the display panel 14-1, the processor 11 acquires user input via the input sensor 16-12 and activates the camera module 17-1. The processor 11 then transmits image data corresponding to the captured image acquired by the camera module 17-1 to the display module 14. The display module 14 can then display the image corresponding to the captured image via the display panel 14-1.
[0070] As another example, when personal information authentication is performed in the display module 14, the fingerprint sensor 16-11 acquires the entered fingerprint information as input data. The processor 11 compares the input data acquired by the fingerprint sensor 16-11 with the authentication data stored in the memory 12, and runs the application based on the comparison result. The display module 14 can display the information executed according to the logic of the application through the display panel 14-1.
[0071] As another example, when the music stream icon displayed on the display module 14 is selected, the processor 11 acquires user input through the input sensors 16-12 and activates the music stream application stored in the memory 12. When a music run command is entered in the music stream application, the processor 11 activates the audio output module 16-3 to provide the user with audio information that corresponds to the music run command.
[0072] The above provides a brief explanation of the operation of the electronic device ED. The following section provides a detailed explanation of the structure of the electronic device ED. In the structure of the electronic device ED described below, some parts may be integrated into a single structure, or a single structure may be provided as two or more separate structures.

[0074] The processor 11 can control at least one other component (e.g., hardware or software component) of the electronic device ED connected to the processor 11 by running software, and can perform various data processing or operations. According to one embodiment, as at least part of the data processing or operation, the processor 11 can store instructions or data received from other components (e.g., input module 13, sensor module 16-1, or communication module 17-3) into volatile memory 12-1, process the instructions or data stored in volatile memory 12-1, and store the result data into non-volatile memory 12-2.

The rendering circuit 11-24 can receive image data from the controller 11-21 and render the image data taking into account the pixel arrangement of the display panel 14-1 used in the electronic device ED, etc. At least one of the data conversion circuit 11-22, gamma calibration circuit 11-23, and rendering circuit 11-24 can be integrated into other components (e.g., the main processor 11-1 or the controller 11-21). At least one of the data conversion circuits 11-22, gamma calibration circuits 11-23, and rendering circuits 11-24 can also be integrated into the data driver 14-3 described later.
[0078] The memory 12 may store various types of data used by at least one component of the electronic device ED (e.g., processor 11 or sensor module 16-1), as well as input or output data related to the instructions associated therewith. The memory 12 may include one or more of volatile memory 12-1 and non-volatile memory 12-2.
[0079] The input module 13 can receive instructions or data from the components of the electronic device ED (e.g., processor 11, sensor module 16-1, or audio output module 16-3) from outside the electronic device ED (e.g., a user or external electronic device OD).

The second input module 13-2 may include a connector enabling physical connection to the external electronic device OD, such as an HDMI connector, a USB connector, an SD card connector, or an audio connector (e.g., a headphone connector).
[0081] Display module 14 provides information to the user visually. Display module 14 may include: display panel 14-1, scan driver 14-2, and data driver 14-3. Display module 14 may also include a chassis and bracket for protecting display panel 14-1.
[0082] The display panel 14-1 may include a liquid crystal display panel, an organic light-emitting display panel, or an inorganic light-emitting display panel; there is no particular limitation on the type of display panel 14-1. The display panel 14-1 may be rigid or flexible, capable of being rolled or folded. The display module 14 may also include supports, brackets, or heat dissipation components for supporting the display panel 14-1. A detailed description of the display panel 14-1 will follow. Figure 3 This will be discussed later.
[0083] The scan driver 14-2 can be mounted as a driver chip on the display panel 14-1. Furthermore, the scan driver 14-2 can be integrated into the display panel 14-1. For example, the scan driver 14-2 may include an amorphous silicon TFT gate driver circuit (ASG), a low-temperature polycrystalline silicon (LTPS) TFT gate driver circuit, or an oxide semiconductor TFT gate driver circuit (OSG) built into the display panel 14-1. The scan driver 14-2 receives control signals from the controller 11-21 and outputs scan signals to the display panel 14-1 in response to the control signals.
[0084] The display panel 14-1 may also include a light-emitting driver. The light-emitting driver outputs a light-emitting control signal to the display panel 14-1 in response to a control signal received from the controller 11-21. The light-emitting driver may be formed separately from the scan driver 14-2, or it may be integrated into the scan driver 14-2.
[0085] The data driver 14-3 receives a control signal from the controller 11-21 and, in response to the control signal, converts the image data into an analog voltage (e.g., a data voltage) and then outputs the data voltage to the display panel 14-1.
[0086] The data driver 14-3 can be integrated into other components (e.g., controller 11-21). The functions of the interface conversion circuit and timing control circuit of the controller 11-21 described above can also be integrated into the data driver 14-3.
[0087] The display module 14 may also include a light-emitting driver and a voltage generating circuit. The voltage generating circuit can output various voltages required to drive the display panel 14-1.

Sensor module 16-1 may include one or more of fingerprint sensor 16-11, input sensor 16-12, and digitizer 16-13.
[0091] The fingerprint sensor 16-11 can generate data values corresponding to the user's fingerprint. The fingerprint sensor 16-11 can include either optical or capacitive fingerprint sensors.
[0092] Input sensor 16-12 can generate data values corresponding to coordinate information based on user body input or pen input. Input sensor 16-12 generates data values based on capacitance changes based on the input. Input sensor 16-12 can sense input based on a passive pen or transmit and receive data with an active pen.
[0093] Input sensors 16-12 can also measure biometric signals such as blood pressure, water content, or body fat. For example, if a user places a part of their body in contact with the sensor layer or detection panel and does not move it for a certain period of time, input sensors 16-12 can sense biometric signals based on changes in the electric field of the body part and output the information required by the user to the display module 14.

[0097] At least one of the fingerprint sensor 16-11, the input sensor 16-12, and the digitizer 16-13 can be integrated into the display panel 14-1. That is, at least one of the fingerprint sensor 16-11, the input sensor 16-12, and the digitizer 16-13 can be formed simultaneously by the process of forming the elements (e.g., light-emitting elements, transistors, etc.) included in the display panel 14-1.
[0098] In addition, sensor module 16-1 can generate electrical signals or data values corresponding to the internal or external states of electronic device ED. Sensor module 16-1 may also include, for example, a posture sensor, a gyroscope sensor, a barometric pressure sensor, a magnetic sensor, an accelerometer, a grip sensor, a proximity sensor, a color sensor, an infrared (IR) sensor, a biometric sensor, a temperature sensor, a humidity sensor, or an illuminance sensor.

The various types of communication modules 17-3 described above can be implemented by a single chip or by separate chips.
[0104] Input module 13, sensor module 16-1, camera module 17-1, etc. can be linked with processor 11 and used to control the operation of display module 14.
[0105] The processor 11 outputs instructions or data to the display module 14, audio output module 16-3, camera module 17-1, or lighting module 17-2 based on the input data received from the input module 13. For example, the processor 11 can generate image data corresponding to input data received via a mouse or active pen and output it to the display module 14, or generate instruction data corresponding to the input data and output it to the camera module 17-1 or lighting module 17-2. If no input data is received from the input module 13 within a specified period, the processor 11 can switch the operating mode of the electronic device ED to a low-power mode or a sleep mode, thereby reducing the power consumed by the electronic device ED.
[0106] The processor 11 outputs instructions or data to the display module 14, the audio output module 16-3, the camera module 17-1, or the lighting module 17-2 based on the detection data received from the sensor module 16-1. For example, the processor 11 can compare the authentication data applied by the fingerprint sensor 16-11 with the authentication data stored in the memory 12, and run the application based on the comparison result. The processor 11 can run instructions or output corresponding image data to the display module 14 based on the detection data sensed by the input sensor 16-12 or the digitizer 16-13. If the sensor module 16-1 includes a temperature sensor, the processor 11 can also receive temperature data related to the temperature measured from the sensor module 16-1, and perform brightness calibration, etc., for the image data based on the temperature data.
[0107] The processor 11 can receive measurement data related to the presence or absence of a user, the user's position, and the user's line of sight from the camera module 17-1. The processor 11 can also perform brightness calibration and other functions on the image data based on the measurement data. For example, the processor 11, which determines the presence or absence of a user based on input from the camera module 17-1, can output image data that has undergone brightness calibration via the data conversion circuit 11-22 or the gamma calibration circuit 11-23 to the display module 14.

The processor 11 can communicate with the display module 14 through an agreed interface, for example, using one of the above-described communication methods, but is not limited to the above-described communication methods.

The thickness of each of the second adhesive layer AL2 and the third adhesive layer AL3 can be equal to the thickness of the panel protective layer PPL. The thickness of the fourth adhesive layer AL4 can be equal to the thickness of the fifth adhesive layer AL5.

[0192] The widths of the electronic panel EP, the shock-absorbing layer ISL, the panel protective layer PPL, and the third and fourth adhesive layers AL3 and AL4 can be greater than the widths of the window protective layer WP and the first adhesive layer AL1. The borders of the electronic panel EP, the shock-absorbing layer ISL, the panel protective layer PPL, and the third and fourth adhesive layers AL3 and AL4 can be positioned further outward than the borders of the window protective layer WP and the first adhesive layer AL1.
[0193] The width of the window WIN and the second adhesive layer AL2 can be smaller than the width of the window protective layer WP and the first adhesive layer AL1. The width of the second adhesive layer AL2 can be smaller than the width of the window WIN. The border of the window WIN can be positioned further inward than the borders of the window protective layer WP and the first adhesive layer AL1.

The borders of the barrier layer BRL and the fifth and sixth adhesive layers AL5 and AL6 can be positioned further inward than the borders of the window protection layer WP and the first adhesive layer AL1.
[0195] The support plate PLT can be configured below and support the display unit DSP. The support plate PLT can also be configured below and support the electronic panel EP. The width of the support plate PLT can be substantially the same as the width of the electronic panel EP. The support plate PLT can have greater rigidity than the display unit DSP.
[0196] The support plate (PLT) can contain non-metallic materials. For example, the support plate (PLT) can include a reinforcing fiber composite material. The reinforcing fiber composite material can be carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFRP).
[0197] The support plate PLT can incorporate reinforcing fiber composite materials to achieve lightweighting. By incorporating reinforcing fiber composite materials, the support plate PLT can achieve a similar level of modulus and strength to a metal support plate while maintaining a lighter weight compared to a metal support plate. Furthermore, by incorporating reinforcing fiber composite materials, the support plate PLT can be more easily shaped compared to a metal support plate. For example, the support plate PLT incorporating reinforcing fiber composite materials can be more easily processed using laser technology or microblasting. However, this is merely illustrative and not limited to these examples; the support plate PLT may also incorporate metallic materials.
[0198] The support plate PLT may include: a first non-folding portion PLT1, a folding portion PLF, and a second non-folding portion PLT2. The first non-folding portion PLT1 may overlap with a first non-folding region NFA1. The folding portion PLF may overlap with a folding region FA. The second non-folding portion PLT2 may overlap with a second non-folding region NFA2.
[0199] Multiple openings OP can be defined in the folded portion PLF. The openings OP can be formed by extending a portion of the support plate PLT along the third direction DR3. When viewed from the second direction DR2, the openings OP can be arranged spaced apart from each other in the first direction DR1. The openings OP can be formed using the aforementioned laser process or micro-blowing process.
[0200] By defining an opening OP in the portion of the support plate PLT that overlaps with the folding region FA, the flexibility of the portion of the support plate PLT overlapping the folding region FA can be improved. As a result, the support plate PLT can be folded around the folding region FA.
[0201] The TPU cover layer can be disposed on the lower surface PLT-L of the support plate PLT. The TPU cover layer can also be disposed on the lower surface of the folded portion PLF. The TPU cover layer can overlap with the opening OP. The TPU cover layer can cover the opening OP below the folded portion PLF. The width of the portion forming the opening OP can be the same as the width of the TPU cover layer. The TPU cover layer can prevent moisture and foreign substances from entering the opening OP.
[0202] Although not illustrated, the display device DD may also include a digitizing board, a shielding layer, and a heat dissipation layer disposed below the support plate PLT.
[0203] Reference Figure 9BThe 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 non-bending region AA2 of the electronic panel EP. The data drive unit DDV may be disposed below the second non-bending region AA2 of the electronic panel EP.
[0204] The printed circuit board (PCB) can be connected to the second non-bent area AA2 of the electronic panel EP. The PCB can be connected to one side of the second non-bent area AA2. The bent area BA is bent, so the second non-bent area AA2 can be positioned below the first non-bent area AA1. Therefore, the data drive unit DDV and the PCB can be positioned below the first non-bent area AA1.

Figure 12 The laminated structure of fibers RP1 and RP2 constituting the support plate PLT is shown in more detail below. For ease of explanation, Figure 12 The opening OP is omitted in the middle (refer to) Figure 10 A diagram illustrating the specific constituent elements of (etc.). Figure 11 It is aimed at Figure 10 An enlarged 3D view of the WW' region shown. Figure 13A and Figure 13B Show respectively with Figure 11 The cross section of the support plate PLT corresponding to the Ⅱ-Ⅱ' section line shown. Figure 13A The laminated structure of fibers RP1 and RP2 constituting the support plate PLT is shown in more detail below. Figure 13B The layered structure of the first part S1 and the second part S2 constituting the support plate PLT is shown in more detail. Figure 13C Showing with Figure 11 The cross section of the support plate PLT corresponding to the Ⅲ-Ⅲ' section line shown. Figure 13D A cross-section of the support plate PLT-1 according to another embodiment of the present invention is shown.
[0207] Reference Figure 10 and Figure 11When viewed in a planar view, the support plate PLT can have a rectangular shape, having a short side extending along the first direction DR1 and a long side extending along the second direction DR2. However, this is only illustrative, and the shape of the support plate PLT can vary.
[0208] The support plate PLT may include: a first non-folding portion PLT1, a folding portion PLF, and a second non-folding portion PLT2. The folding portion PLF may be disposed between the first non-folding portion PLT1 and the second non-folding portion PLT2. The first non-folding portion PLT1, the folding portion PLF, and the second non-folding portion PLT2 may be arranged in a first direction DR1. The first non-folding portion PLT1 and the second non-folding portion PLT2 may be respectively connected to... Figure 7 and Figure 9A The first non-folded region NFA1 and the second non-folded region NFA2 shown overlap. The folded portion PLF can be with... Figure 7 and Figure 9A The folded regions FA shown overlap.
[0209] As an example, each of the first non-folding portion PLT1 and the second non-folding portion PLT2 may have a quadrilateral shape parallel to the plane defined by the first direction DR1 and the second direction DR2. However, this is not a limitation, and the shapes of the first non-folding portion PLT1 and the second non-folding portion PLT2 may vary.
[0210] A grid pattern can be defined in the folded section PLF. For example, multiple openings OP can be defined in the folded section PLF. The openings OP can be arranged according to a prescribed rule. The openings OP can be arranged in a grid pattern, thereby forming a grid pattern in the folded section PLF.
[0211] The openings OP can be arranged in both the first direction DR1 and the second direction DR2. When viewed in a plane, adjacent openings OP in the first direction DR1 can be staggered. The openings OP can extend further in the second direction DR2 than in the first direction DR1. That is, the openings OP can extend in a direction parallel to the folding axis FX.
[0212] Although not shown, the folded portion PLF may include a plurality of branches extending along a first direction DR1 and a plurality of support portions extending along a second direction DR2. The support portions may be disposed between adjacent openings OP in the first direction DR1. The branches may be disposed between adjacent openings OP in the second direction DR2. The branches may connect adjacent support portions in the first direction DR1.
[0213] The folded portion PLF may include a first region A1 and a second region A2 adjacent to the first region A1. The first region A1 may refer to a region defining a plurality of recessed patterns SP, and the second region A2 may refer to a region defining a plurality of openings OP. The plurality of recessed patterns SP may be defined in the first region, and the plurality of openings OP may be defined in the second region.
[0214] Reference Figure 11 and Figure 13A The support plate PLT may include multiple fibers RP1, RP2 stacked on the third-direction DR3. The support plate PLT includes carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFRP). In this specification, fibers RP1, RP2 may refer to carbon fiber reinforced plastic (CFRP) or glass fiber reinforced plastic (GFRP).
[0215] The support plate PLT may include a first layer SS1 and a second layer SS2 disposed on the first layer SS1. The first layer SS1 includes a plurality of first fibers RP1, and the second layer SS2 includes a plurality of second fibers RP2.
[0216] The first fiber RP1 can extend along the first direction DR1, and a plurality of first fibers RP1 are arranged side by side along the second direction DR2. In contrast, the second fiber RP2 can extend along the second direction, and a plurality of second fibers RP2 are arranged side by side along the first direction DR1. For example, the second fiber RP2 can extend along the folding axis FX (see reference). Figure 10 It extends in the parallel second direction DR2.
[0217] Reference Figure 11 , Figure 13A as well as Figure 13B The plurality of first fibers RP1 may include a plurality of first-1 fibers RP1-1 and a plurality of first-2 fibers RP1-2. The plurality of first-2 fibers RP1-2 may be disposed on the plurality of first-1 fibers RP1-1. The first-2 fibers RP1-2 may be arranged correspondingly to the first-1 fibers RP1-1. The plurality of second fibers RP2 may include a plurality of second-1 fibers RP2-1 and a plurality of second-2 fibers RP2-2. The plurality of second-2 fibers RP2-2 may be disposed on the plurality of second-1 fibers RP2-1. The second-2 fibers RP2-2 may be arranged correspondingly to the second-1 fibers RP2-1. However, this is merely an illustrative representation of the structure in which the first fibers RP1 and second fibers RP2 are stacked in multiple layers in the first layer SS1 and the second layer SS2; the first fibers RP1 and second fibers RP2 may be stacked in three or more layers.
[0218] The first layer SS1 can refer to a layer with multiple recessed patterns SP defined thereon. The first layer SS1 includes a first surface in contact with the second layer SS2 and a second surface opposite to the first surface, on which multiple recessed patterns SP are defined. The recessed patterns SP can be recessed from the second surface toward the first surface. For example, the support plate PLT can have the following structure: the second layer SS2 is directly disposed on the first layer SS1, and the first upper surface TS of the first layer SS1 contacts the second layer SS2, and multiple recessed patterns SP are defined on the first lower surface BS of the first layer SS1. The multiple recessed patterns SP can be recessed from the first lower surface BS of the first layer SS1 toward the second layer SS2. The recessed patterns SP can be formed by penetrating the first-1 fiber RP1-1 in the third direction DR3 and causing a portion of the first-2 fiber RP1-2 to be recessed toward the second layer SS2. However, the embodiment is not limited to this; unlike the illustration, the recessed patterns SP can be formed by causing a portion of the first-1 fiber RP1-1 to be recessed toward the second layer SS2 in the third direction DR3, but not defining a pattern on the first-2 fiber RP1-2. Alternatively, if the first layer SS1 is a structure in which multiple first fibers RP1 are stacked in n layers (n being an integer greater than or equal to 3), the multiple first fibers RP1 may include fibers 1-1 to 1-n (RP1-1 to RP1-n, not shown). In this case, the recessed pattern SP may be a pattern formed by recessing a portion of the first fiber RP1-1 toward the second layer SS2 on the third direction DR3, but not defined on the first 2 to 1-n fibers (RP1-2 to RP1-n, not shown). Alternatively, it may be formed by penetrating the first 1 to the first (n-1) fibers (RP1-1 to RP1-(n-1), not shown) and recessing a portion of the first (n) fiber RP1-n (not shown) toward the second layer SS2, but the embodiment is not limited to this.
[0219] The first layer SS1 may include a first portion S1 and a second portion S2. The first portion S1 may be the portion adjacent to the second layer SS2 in a third direction DR3. The second portion S2 may be the portion separated from the second layer SS2 in cross section by the first portion S1. The recessed pattern SP may penetrate the second portion S2 to expose one side of the first portion S1. The recessed pattern SP may not be defined on the first portion S1. For example, the support plate PLT may have the following structure: the first portion S1 is disposed on the second portion S2, the second layer SS2 is disposed on the first layer SS1, and the recessed pattern SP penetrates the second portion S2 to expose the lower surface of the first portion S1. The second portion S2 may include a portion of the first-1 fiber RP1-1 and the first-2 fiber RP1-2, and the first portion S1 may include another portion of the first-2 fiber RP1-2, but the embodiment is not limited thereto.
[0220] ReferenceFigure 11 , Figure 13A as well as Figure 13C The support plate PLT may include a first region A1 and a second region A2 adjacent to the first region A1. In one embodiment, the folding portion PLF (see reference) Figure 10 The region A1 may include a first region A1 and a second region A2. The first region A1 may refer to an area defining multiple recessed patterns SP, and the second region A2 may refer to an area defining multiple openings OP. The first region A1 may be related to the non-display region NDA (see reference). Figure 1 The first region A1 may overlap with part of the electronic device ED (see reference). Figure 1 The borders of the ) are defined adjacent to each other.
[0221] The opening OP may include a first opening OP1 defined in the first layer SS1 and a second opening OP2 defined in the second layer SS2. A recessed pattern SP may be formed corresponding to the first opening OP1. The recessed pattern SP may be configured to extend from the first opening OP1 along a first horizontal direction, and multiple recessed patterns SP may be arranged side-by-side along a second horizontal direction that intersects the first horizontal direction in a plane. For example, the recessed pattern SP may be configured to extend from the first opening OP1 along a second direction DR2, and multiple recessed patterns SP may be arranged side-by-side along the first direction DR1. However, this is not a limitation; it may also be configured, as needed, that multiple recessed patterns SP are arranged side-by-side along the second direction DR2, and that the recessed patterns SP extend from the first opening OP1 along the first direction DR1.
[0222] Additionally, a recessed pattern SP may be undefined in the second layer SS2 overlapping with the first region A1 and in a portion of the first layer SS1. In the first portion S1 of the first layer SS1 overlapping with the first region A1 (refer to...) Figure 13B The second layer SS2, which overlaps with the first region A1, may not have a defined recessed pattern SP. Even if the second layer SS2 without a defined recessed pattern SP is included in the fold PLF (see reference...) Figure 10 As the second layer SS2 extends in the direction of its extension (DR2) and folds along the axis FX (see reference). Figure 10 Parallel and having a relatively small modulus value when folded, it can have a certain level of folding ease. Alternatively, the first portion S1 of the first layer SS1 overlapping the first region A1 (refer to...) Figure 13B The first fiber RP1 included in the first layer A1 and a portion of the second fiber RP2 included in the second layer SS2 overlapping with the first region A1 can also be in a cut shape. With the inclusion of the first fiber RP1 and the second fiber RP2 in a cut shape, a certain level of folding ease can be achieved.

The third fibers RP3 may extend along a second direction DR2, and the plurality of third fibers RP3 may be arranged side-by-side along a first direction DR1. The plurality of third fibers RP3 may be arranged in the same direction as the plurality of second fibers RP2, and in a direction orthogonal to the plurality of first fibers RP1 in a plane. The plurality of third fibers RP3 may include a plurality of third-first fibers RP3-1 and a plurality of third-second fibers RP3-2. The plurality of third-second fibers RP3-2 may be disposed on the plurality of third-first fibers RP3-1. The third-second fibers RP3-2 may be arranged correspondingly to the third-first fibers RP3-1.
[0225] Multiple recessed patterns SP can be defined on the first lower surface BS of the first layer SS1, and multiple lower holes HH1 corresponding to the recessed patterns SP are defined on the lower layer DSL. The lower holes HH1 can be shaped to connect with the recessed patterns SP in cross-section. However, this is only to illustrate the structure of the support plate PLT-1 with three or more layers SS1, SS2, DSL stacked together. The support plate PLT-1 can also include a structure with four or more layers stacked together. When the support plate PLT-1 has a structure with three or more layers stacked together, the arrangement directions between adjacent layers can be orthogonal in the plane.

The multiple recessed patterns SP can be recessed from the first upper surface TS of the first layer SS1a toward the second layer SS2a.
[0230] Reference Figure 14C The support plate PLTa-1 may include: a first layer SS1a, a second layer SS2a disposed below the first layer SS1a, and an upper layer US disposed above the first layer SS1a.

The upper holes HH2 can be in a form that connects to the recessed patterns SP in cross-section. Although not shown, the support plate PLTa-1 can also include a structure consisting of four or more layers stacked together, in which case the arrangement directions between adjacent layers can be orthogonal in the plane.

In the support plate PLTb, the first region A1 may be adjacent to the display region DA (see reference). Figure 1 Part of it overlaps. Figure 15A With the aforementioned Figure 11 In contrast, in the support plate PLTb, the first region A1 is not connected to the electronic device ED (see reference). Figure 1 Instead of being adjacent to the border of the electronic device ED (see reference), it can be defined as being adjacent to the border of the electronic device ED (see reference).

The electronic device according to an embodiment of the present invention includes an opening overlapping a folded region. The manufacturing process of the electronic device according to an embodiment of the present invention may include a step of deforming the grid pattern of the opening.
