[0091] The present invention will now be described in detail with reference to exemplary embodiments thereof, examples of which are illustrated in the accompanying drawings. Wherever possible, the same element symbols are used in the drawings and description to denote the same or similar parts.

[0092] Throughout this specification and the appended claims, certain terms are used to refer to specific components. Those skilled in the art will understand that electronic device manufacturers may use different names to refer to the same components. This document is not intended to distinguish between components that have the same function but different names. In the following specification and claims, words such as "containing" and "comprising" are open-ended terms and should therefore be interpreted as "containing but not limited to...".

[0093] The directional terms used herein, such as "up," "down," "front," "back," "left," and "right," are for reference only to the accompanying drawings. Therefore, the directional terms used are for illustrative purposes and not for limiting this disclosure. In the accompanying drawings, each figure illustrates general features of the methods, structures, and / or materials used in specific embodiments. However, these figures should not be construed as defining or limiting the scope or nature covered by these embodiments. For example, for clarity, the relative dimensions, thicknesses, and positions of various films, regions, and / or structures may be reduced or enlarged.

[0094] In this disclosure, a structure (or layer, component, substrate) located above / above another structure (or layer, component, substrate) can refer to the two structures being adjacent and directly connected, or to the two structures being adjacent but not directly connected. Indirect connection means that there is at least one intermediate structure (or intermediate layer, intermediate component, intermediate substrate, intermediate spacer) between the two structures, with the lower surface of one structure adjacent to or directly connected to the upper surface of the intermediate structure, and the upper surface of the other structure adjacent to or directly connected to the lower surface of the intermediate structure. The intermediate structure can be composed of a single-layer or multi-layer solid structure or non-solid structure, without limitation. In this disclosure, when a structure is positioned "on" another structure, it may mean that the structure is "directly" on the other structure, or that the structure is "indirectly" on the other structure, meaning that at least one structure is sandwiched between the structure and the other structures.

[0095] The terms “approximately,” “equal to,” “equivalent to,” “same,” “substantially,” or “proximately” are generally interpreted as being within 20% of a given value or range, or as being within 10%, 5%, 3%, 2%, 1%, or 0.5% of a given value or range.

[0096] Furthermore, any two values ​​or directions used for comparison may have a certain degree of error. If the first value equals the second value, it implies that there may be an error of about 10% between the first and second values; if the first direction is perpendicular to or "approximately" perpendicular to the second direction, then the angle between the first and second directions may be between 80 and 100 degrees; if the first direction is parallel to or "approximately" parallel to the second direction, then the angle between the first and second directions may be between 0 and 10 degrees.

[0097] The ordinal numbers used in the specification and claims, such as "first," "second," etc., to modify elements, do not in themselves imply or represent any prior ordinal number for that (or these) element, nor do they represent the order of one element with another, or the order of manufacturing processes. The use of these ordinal numbers is solely to clearly distinguish one named element from another element with the same name. The claims and specification may not use the same terminology; therefore, a first element in the specification may be a second element in the claims.

[0098] In this disclosure, Young's modulus can be measured using a Young's modulus tester, a tensile testing machine, or other suitable instruments or methods, but is not limited thereto. Furthermore, the terms "given range is from a first value to a second value" or "given range falls within the range of the first value to the second value" indicate that the given range includes the first value, the second value, and other values ​​in between.

[0099] Furthermore, the electronic devices disclosed herein may include, but are not limited to, display devices, backlight devices, antenna devices, sensing devices, splicing devices, touch displays, curved displays, or free-shape displays. Electronic devices may include, for example, liquid crystal, light-emitting diodes, fluorescent, phosphorescent, other suitable display media, or combinations thereof, but are not limited to these. Display devices may be non-emissive or self-emissive. Antenna devices may be liquid crystal or non-liquid crystal antenna devices, and sensing devices may be sensing capacitance, light, heat, or ultrasound, but are not limited to these. Splicing devices may be, for example, display splicing devices or antenna splicing devices, but are not limited to these. It should be noted that electronic devices may be any of the aforementioned arrangements and combinations, but are not limited to these. Furthermore, electronic devices may be bendable or flexible. It should be noted that electronic devices may be any of the aforementioned arrangements and combinations, but are not limited to these. Furthermore, the electronic device can be rectangular, circular, polygonal, have curved edges, or other suitable shapes. The electronic device may have peripheral systems such as a drive system, control system, light source system, and shelving system to support display devices, antenna devices, or splicing devices. For ease of explanation, the following description will use the example of an electronic device as a backlight device, but this disclosure is not limited thereto.

[0100] It should be understood that, according to embodiments of this disclosure, the depth, thickness, width, or height of each element, or the spacing or distance between elements, can be measured using an optical microscope (OM), a scanning electron microscope (SEM), an alpha-step thickness gauge, an ellipsometry, or other suitable methods. According to some embodiments, a scanning electron microscope can be used to obtain a cross-sectional image containing the elements to be measured, and to measure the depth, thickness, width, or height of each element, or the spacing or distance between elements.

[0101] It should be understood that the features described below can be replaced, recombined, or mixed in several different embodiments to complete other embodiments without departing from the spirit of this disclosure. Features between embodiments can be arbitrarily mixed and combined as long as they do not violate the spirit of the invention or conflict with it.

[0102] Unless otherwise defined, all terms used herein (including technical and scientific terms) have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure pertains. It is understood that such terms, for example, as defined in commonly used dictionaries, should be interpreted as having a meaning consistent with the relevant art and the background or context of this disclosure, and should not be interpreted in an idealized or overly formal manner, unless specifically defined in embodiments of this disclosure.

[0103] Panel 100 may include, but is not limited to, a foldable region 110, a first region 120, and a second region 130. The foldable region 110 may be located between the first region 120 and the second region 130, but is not limited to this. In some embodiments, the foldable region 110 may connect the first region 120 and the second region 130, but is not limited to this. The first region 120 and the second region 130 may, for example, be non-foldable regions. In some embodiments, the radius of curvature of the foldable region 110 is modulated in cross-sectional view. In some embodiments, the radius of curvature of the first region 120 and / or the second region 130 is, for example, not modulated in cross-sectional view. In some embodiments, the foldable region 110 has a folding axis AX. In some embodiments, panel 100 may include a display panel, a sensing panel, a light-emitting panel, an antenna panel, or other suitable panels or combinations thereof. In some embodiments, panel 100 may include an organic light-emitting diode (OLED) panel, a mini LED panel, a micro LED panel, a quantum dot LED panel, or a liquid crystal display (LCD) panel, an antenna panel, or a sensing panel, but is not limited thereto. In some embodiments, panel 100 may include various passive and active components, such as capacitors, resistors, inductors, diodes, transistors, etc., wherein the diode may include a light-emitting diode or a photodiode. The light-emitting diode may include, for example, an organic light-emitting diode (OLED), a mini LED, a micro LED, a quantum dot LED, other suitable light-emitting diodes, or combinations thereof, but is not limited thereto. In some embodiments, when panel 100 is a display panel, the first region 120 and the second region 130 may be used to display an image, and the foldable region 110 may also be selectively used to display an image.

[0104] Please see Figure 1 and Figure 2A support piece 200 is disposed below the panel 100, and the support piece 200 is configured, for example, to support the aforementioned panel 100. The support piece 200 includes a foldable portion 210, a first non-foldable portion 220, and a second non-foldable portion 230, but is not limited thereto. The foldable portion 210 may be connected between the first non-foldable portion 220 and the second non-foldable portion 230, but is not limited thereto. In other words, the first non-foldable portion 220 may be connected to the foldable portion 210, and the second non-foldable portion 230 may be connected to the foldable portion 210. The foldable portion 210 may have a plurality of openings 211.

[0105] When the panel 100 is placed on the support piece 200, the foldable portion 210 can overlap the foldable area 110, the first non-foldable portion 220 can overlap the first area 120, and the second non-foldable portion 230 can overlap the second area 130.

[0106] The first non-foldable portion 220 has a first hole V1, which may be adjacent to the foldable portion 210. For example... Figure 2 As shown, a virtual line L1 can be defined as a virtual line tangent to the edge of the first hole V1 away from the edge 2221A and approximately perpendicular to the folding axis AX. The detailed edge 2221A can be found in the following description. Similarly, the first non-foldable portion 220 may have a fourth hole V4, which may be adjacent to the foldable portion 210. Figure 2 As shown, the first hole V1 and the fourth hole V4 can, for example, separate different corners of the adjacent foldable portion 210, but are not limited thereto. Figure 2 As shown, a virtual line L4 can be defined as a virtual line tangent to the edge of the fourth hole V4 away from the edge 2231A and approximately perpendicular to the folding axis AX. The detailed edge 2231A can be referred to the following description. The first non-foldable portion 220 can be divided, for example, by virtual lines L1 and L4 into a body 221, an upper block 222, and a lower block 223. The body 221 can be located between or connected to the upper block 222 and the lower block 223. The upper block 222 can be defined as the block above the virtual line L1, and the lower block 223 can be defined as the block below the virtual line L4.

[0107] The first non-foldable portion 220 (e.g., the upper block 222) may include, but is not limited to, a first portion 2221, a second portion 2222, and a third portion 2223. The first portion 2221 may be closer to the foldable portion 210 than the second portion 2222, and the second portion 2222 may be closer to the foldable portion 210 than the third portion 2223. Therefore, the first portion 2221 may be located between the foldable portion 210 and the second portion 2222, and the second portion 2222 may be located between the first portion 2221 and the third portion 2223.

[0108] like Figure 2 and Figure 3 As shown, the first portion 2221 of the first non-foldable portion 220 may have a first hole V1, and in a first direction N1 parallel to the folding axis AX, the first portion 2221 protrudes more than the second portion 2222. In other words, the first portion 2221 is defined, for example, as the portion above the virtual line L1 that protrudes more significantly in the first direction N1, the first portion 2221 having the first hole V1, while the second portion 2222 is located on the side of the first portion 2221 away from the foldable portion 210.

[0109] In some embodiments, such as Figure 2 In the first direction N1, the width W1 of the first portion 2221 corresponding to the first hole V1 may be greater than the width W2 of the second portion 2222. The width W1 of the first portion 2221 is, for example, measured as the distance in the first direction N1 between the virtual line L1 and the edge 2221A of the first portion 2221, with this distance measured approximately through the center of the first hole V1, and the first direction N1 being approximately perpendicular to the virtual line L1. The width W2 of the second portion 2222 is, for example, measured in the first direction N1 at the width of the intersection of the first portion 2221 and the second portion 2222.

[0110] like Figure 2 and Figure 3 As shown, in the first direction N1, the interval D2 between the first hole V1 and the edge 2221A of the first portion 2221 can be greater than or equal to the width D1 of the first hole V1 (approximately the diameter of the first hole V1). The aforementioned interval D2 can be measured, for example, approximately along the first direction N1 passing through the center of the hole V1 and perpendicular to the virtual line L1. The aforementioned width D1 of the first hole V1 can be measured, for example, approximately along the first direction N1 passing through the center of the hole V1 and perpendicular to the virtual line L1. In some embodiments, in the first direction N1, the ratio of the interval D2 between the first hole V1 and the edge 2221A of the first portion 2221 to the width D1 of the first hole V1 is greater than or equal to 1 and less than or equal to 3 (i.e., 1 ≤ D2 / D1 ≤ 3), but is not limited thereto. In some embodiments, in the first direction N1, the ratio of the interval D2 to the width D1 is greater than or equal to 1.2 and less than or equal to 2.8 (i.e., 1.2 ≤ D2 / D1 ≤ 2.8). In some embodiments, in the first direction N1, the ratio of the interval D2 to the width D1 is greater than or equal to 1.5 and less than or equal to 2.5 (i.e., 1.5 ≤ D2 / D1 ≤ 2.5).

[0111] like Figure 4As shown, if the ratio of interval D2 to width D1 is less than 1, for example because interval D2 is too small, the gap between the first hole V1 and the edge 2221A may break during assembly or manufacturing, resulting in a decrease in the quality or damage to the support piece 200, thus increasing the damage rate. If the ratio of interval D2 to width D1 is greater than 3, for example because interval D2 is too large, warping may occur at this gap during assembly or folding, affecting the yield, thus increasing the damage rate, but not limited to this.

[0112] In some embodiments, the foldable portion 210 includes a plurality of openings 210, and the area of ​​the first opening V1 may be, for example, smaller than the area of ​​one of these openings 211. For instance, the area of ​​the first opening V1 may be greater than or equal to 0.05 square millimeters (mm²). 2 And less than or equal to 0.1 square millimeters (mm) 2 (0.05mm) 2 The area of ​​the first hole V1 is ≤0.1mm². 2 However, this is not the only possibility. In some embodiments, the area of ​​the first hole V1 may be greater than or equal to 0.06 square millimeters (mm²). 2 And less than or equal to 0.09 square millimeters (mm) 2 (0.06mm 2 The area of ​​the first hole V1 is less than or equal to 0.09 mm². 2 In some embodiments, the ratio of the area of ​​the first hole V1 to the area of ​​one of the openings 211 may be greater than or equal to 0.05 and less than or equal to 0.5 (0.05 ≤ area of ​​first hole V1 / area of ​​opening 211 ≤ 0.5), but is not limited thereto. In some embodiments, the ratio of the area of ​​the first hole V1 to the area of ​​opening 211 is between 0.08 and 0.3 (0.08 ≤ area of ​​first hole V1 / area of ​​opening 211 ≤ 0.3), but is not limited thereto. In some embodiments, the radius of curvature of the first hole V1 may be greater than or equal to 0.1 mm and less than or equal to 0.3 mm (0.1 mm ≤ radius of curvature of first hole V1 ≤ 0.3 mm), but is not limited thereto. In some embodiments, the radius of curvature of the first hole V1 may be greater than or equal to 0.12 mm and less than or equal to 0.28 mm (0.12 mm ≤ radius of curvature of the first hole V1 ≤ 0.28 mm).

[0113] In addition, it should be noted that although the first hole V1 in this embodiment is exemplified as a through hole penetrating the support piece 200, in some embodiments, the hole V1 may also be a recess formed on the front or rear surface of the support piece 200 without penetrating the support piece 200.

[0114] Please refer to this again. Figure 1 and Figure 2Compared to the second part 2222, the first part 2221 extends further away, for example, along a direction away from the virtual line L1. Therefore, in the first direction N1, the width W1 of the first part 2221 corresponding to the first hole V1 can be greater than the width W2 of the second part 2222. The definitions of width W1 and width W2 are as described above.

[0115] In some embodiments, the second portion 2222 extends further away from the virtual line L1, for example, compared to the third portion 2223. Therefore, in the first direction N1, the width W2 of the second portion 2222 may be greater than the width W3 of the third portion 2223. The aforementioned width W3 is, for example, measured in the first direction N1 at the boundary between the second portion 2222 and the third portion 2223.

[0116] In some embodiments, the edge 2223A of the third portion 2223 may extend along a second direction N2, which is substantially perpendicular to the first direction N1, and the edge 2222A of the second portion 2222 may extend along a direction different from the first direction N1 and the second direction N2. In some embodiments, the included angle θ between the edges 2222A of the first portion 2221 and the second portion 2222 may be between 60 degrees and 120 degrees, but is not limited thereto.

[0117] In some embodiments, the edge 2222A of the second portion 2222 may have a curved edge or other suitable shape. In some embodiments, the edge 2221A of the first portion 2221 may have a curved edge or other suitable shape.

[0118] Please continue reading. Figure 1 and Figure 2 Similarly, the first non-foldable portion 220 (e.g., the lower block 223) may include, but is not limited to, another first portion 2231, another second portion 2232, and / or another third portion 2233. In other words, the first non-foldable portion 220 includes a first portion 2221 and another first portion 2231, the first portion 2221 being relative to the other first portion 2231 of the first non-foldable portion 220. In some embodiments, the other first portion 2231 is closer to the foldable portion 210 than the other second portion 2232, and the other second portion 2232 is closer to the foldable portion 210 than the other third portion 2233. The other first portion 2231 may be located between the foldable portion 210 and the other second portion 2232, and the other second portion 2232 may be located between the other first portion 2231 and the other third portion 2233.

[0119] Similarly, another first portion 2231 of the first non-foldable portion 220 has a fourth hole V4. As described above, the virtual line L4 can be defined as a virtual line tangent to the edge of the fourth hole V4 away from the edge 2231A (described later) and approximately perpendicular to the folding axis AX. In the first direction N1 parallel to the folding axis AX, the other first portion 2231 protrudes more than the other second portion 2232. The width (not shown) of the other first portion 2231 corresponding to the fourth hole V4 can be greater than the width (not shown) of the other second portion 2232. The width (not shown) of the other first portion 2231 is, for example, measured as the distance between the virtual line L4 and the edge 2231A of the other first portion 2231 in the first direction N1, and the measurement location of this distance is approximately through the center of the fourth hole V4. The width (not shown) of the other second portion 2232 is, for example, measured as the width at the junction of the other first portion 2231 and the other second portion 2232 in the first direction N1.

[0120] Similar (for reference) Figure 3 (As explained by the width D1 and spacing D2), in the first direction N1, the spacing (not shown) between the fourth hole V4 and the edge 2231A of another first portion 2231 may be greater than or equal to the width of the fourth hole V4 (approximately the diameter of the fourth hole V4). The aforementioned spacing (not shown) may, for example, be measured along a line passing through the center of the fourth hole V4 and approximately perpendicular to the virtual line L4. In some embodiments, 1 ≤ spacing (not shown) between the fourth hole V4 and edge 2231A / width of the fourth hole V4 ≤ 3, but is not limited thereto.

[0121] Similar (for reference) Figure 3 (As explained in the section on width D1 and spacing D2), if the ratio of the spacing (not shown) between the fourth hole V4 and edge 2231A to the width (not shown) of the fourth hole V4 is less than 1, the spacing may break during assembly or manufacturing due to the small spacing, resulting in reduced quality or damage to the support piece 200. If the ratio of the spacing between the fourth hole V4 and edge 2231A to the width of the fourth hole V4 is greater than 3, the spacing D2 may be too large, and warping may occur at this spacing during the assembly or folding of the electronic device E, but this is not limited to the above.

[0122] Similarly, the design of the area or radius of curvature of the fourth hole V4 can refer to the design of the first hole V1 mentioned above.

[0123] Similarly, although the fourth hole V4 in this embodiment is exemplified as a through hole penetrating the support piece 200, in some embodiments, the fourth hole V4 may also be a recess formed on the front or rear surface of the support piece 200 without penetrating the support piece 200.

[0124] Similarly, compared to the other second portion 2232, the other first portion 2231 extends further away from the virtual line L4. Therefore, in the first direction N1, the width (not shown) of the other first portion 2231 corresponding to the fourth hole V4 can, for example, be greater than the width (not shown) of the other second portion 2232. The width (not shown) of the other first portion 2231 is measured in the first direction N1 as the distance between the virtual line L4 and the edge 2231A of the other first portion 2231, and this distance is measured approximately through the center of the fourth hole V4. The width (not shown) of the other second portion 2232 is, for example, measured in the first direction N1 at the intersection of the other first portion 2231 and the other second portion 2232.

[0125] Compared to the other third portion 2233, the other second portion 2232 extends further away from the virtual line L4. Therefore, in the first direction N1, the width of the other second portion 2232 can be greater than the width of the other third portion 2233. The width of the other third portion 2233 is, for example, the width along the boundary between the other second portion 2232 and the other third portion 2233 in the first direction N1.

[0126] In some embodiments, the edge 2233A of another third portion 2233 may extend generally along the second direction N2, and the edge 2232A of another second portion 2232 may extend generally along a direction different from the first direction N1 and the second direction N2. In some embodiments, the included angle between the edges 2232A of another first portion 2231 and another second portion 2232 may be between 60 degrees and 120 degrees, but is not limited thereto.

[0127] Similarly, in some embodiments, the edge 2232A of another second portion 2232 or the edge 2231A of another first portion 2231 may have an arc edge or other suitable shape.

[0128] refer to Figure 2Similarly, in some embodiments, the second non-foldable portion 230 may have a second hole V2 and a third hole V3, which may, for example, be located at different corners adjacent to the foldable portion 210, but are not limited thereto. A virtual line L2 may be defined as a virtual line tangent to the edge of the second hole V2 remotely adjacent to the edge 2321A and substantially perpendicular to the folding axis AX, the details of which can be found in the following description. Similarly, a virtual line L3 may be defined as a virtual line tangent to the edge of the third hole V3 remotely adjacent to the edge 2331A and perpendicular to the folding axis AX, the details of which can be found in the following description. Similarly, the second non-foldable portion 230 may be divided, for example, by virtual lines L2 and L3 into a body 231, an upper block 232, and a lower block 233. The body 231 is located between or connected to the upper block 232 and the lower block 233. The upper block 232 may be the block above the virtual line L2, and the lower block 233 may be the block below the virtual line L3.

[0129] Similar to the first non-foldable portion 220, the upper block 232 of the second non-foldable portion 230 includes, but is not limited to, a first portion 2321, a second portion 2322, and a third portion 2323. The first portion 2321 is closer to the foldable portion 210 than the second portion 2322, and the second portion 2322 is closer to the foldable portion 210 than the third portion 2323. The first portion 2321 may be located between the foldable portion 210 and the second portion 2322, and the second portion 2322 may be located between the first portion 2321 and the third portion 2323.

[0130] The first portion 2321 of the second non-foldable portion 230 includes a second hole V2. In the first direction N1, the width (not shown) of the first portion 2321 corresponding to the second hole V2 may be greater than the width (not shown) of the second portion 2322. The width (not shown) of the first portion 2321 is, for example, measured as the distance in the first direction N1 between the virtual line L2 and the edge 2321A of the first portion 2321, and the measurement position of this distance is approximately through the center of the second hole V2. The first direction N1 may also be, for example, perpendicular to the extension of the virtual line L2. The width (not shown) of the second portion 2322 is, for example, measured in the first direction N1 at the width at the junction of the first portion 2321 and the second portion 2322.

[0131] In some embodiments, in the first direction N1, the width of the second hole V2 (approximately the diameter of the second hole V2) may be less than or equal to the interval (not shown) between the second hole V2 and the edge 2321A of the first portion 2321. This interval may, for example, be measured approximately along the virtual line L2 passing through the center of the second hole V2. In some embodiments, 1 ≤ the interval between the second hole V2 and the edge 2321A / the width of the second hole V2 ≤ 3, but this is not a limitation, and design advantages can be found in the description of the aforementioned interval D2 and width D1.

[0132] In some embodiments, the area of ​​the second hole V2 may be smaller than the area of ​​the opening 211 on the foldable portion 210. The design of the area, size, or radius of curvature of the second hole V2 may refer to the first hole V1 as described above. In some embodiments, the area, size, or radius of curvature of the second hole V2 may be the same as or different from that of the first hole V1.

[0133] Although the second hole V2 in this embodiment is exemplified as a through hole penetrating the support piece 200, in some embodiments, the second hole V2 may also be a recess formed on the front or rear surface of the support piece 200 without penetrating the support piece 200.

[0134] As described above, compared to the second portion 2322, the first portion 2321 extends further away along a direction away from the virtual line L2. In the first direction N1, the width (not shown) of the first portion 2321 corresponding to the second hole V2 can be greater than the width of the second portion 2322. The definition of the first portion 2321 corresponding to the width (not shown) of the second hole V2 being greater than the width of the second portion 2322 can be found above.

[0135] In some embodiments, the second portion 2322 extends further away from the virtual line L2 than the third portion 2323. In the first direction N1, the width (not shown) of the second portion 2322 may be greater than the width (not shown) of the third portion 2323. The width (not shown) of the third portion 2323 is, for example, measured in the first direction N1 at the intersection of the second portion 2322 and the third portion 2323.

[0136] In some embodiments, the edge 2323A of the third portion 2323 may extend, for example, generally along the second direction N2, and the edge 2322A of the second portion 2322 may extend, for example, generally along a direction different from the first direction N1 and the second direction N2. In some embodiments, the included angle between the edges 2322A of the first portion 2321 and the second portion 2322 may be between 60 degrees and 120 degrees, but is not limited thereto.

[0137] In some embodiments, the edge 2322A of the second portion 2322 and / or the edge 2321A of the first portion 2321 may have an arc edge or other suitable shape.

[0138] Similarly, the lower block 233 of the second non-foldable portion 230 includes, but is not limited to, another first portion 2331, another second portion 2332, and another third portion 2333. In other words, the second non-foldable portion 230 includes a first portion 2321 and another first portion 2331, the first portion 2321 being relative to the other first portion 1331 of the second non-foldable portion 230. Similarly, the other first portion 2331 is closer to the foldable portion 210 than the other second portion 2332, and the other second portion 2332 is closer to the foldable portion 210 than the other third portion 2333. The other first portion 2331 may be located between the foldable portion 210 and the other second portion 2332, and the other second portion 2332 may be located between the other first portion 2331 and the other third portion 2333.

[0139] Similarly, another first portion 2331 of the second non-foldable portion 230 may have a third hole V3, and in a first direction N1 parallel to the folding axis AX, the other first portion 2331 protrudes more than the other second portion 2332. In some embodiments, in the first direction N1, the width (not shown) of the other first portion 2331 corresponding to the third hole V3 may be greater than the width (not shown) of the other second portion 2332. The width of the other first portion 2331 is, for example, measured as the distance in the first direction N1 between the virtual line L3 and the edge 2331A of the other first portion 2331, and this distance is measured approximately through the center of the third hole V3, and the first direction N1 is, for example, approximately perpendicular to the virtual line L3. The width (not shown) of the other second portion 2332 is, for example, measured in the first direction N1 at the width at the junction of the other first portion 2331 and the other second portion 2332.

[0140] In some embodiments, in the first direction N1, the width of the third hole V3 (approximately the diameter of the third hole V3) is less than or equal to the interval (not shown) between the third hole V3 and the edge 2331A of another first portion 2331. This interval can be measured, for example, approximately along an extension passing through the center of the third hole V3 and perpendicular to the virtual line L3. In this embodiment, 1 ≤ the interval between the third hole V3 and edge 2331A / the width of the third hole V3 ≤ 3.

[0141] In some embodiments, the area of ​​the third hole V3 may be smaller than the area of ​​the opening 211 on the foldable portion 210. The design of the area, size, or radius of curvature of the third hole V3 may refer to the first hole V1 as described above. In some embodiments, the area, size, or radius of curvature of the third hole V3 may be the same as or different from that of the first hole V1.

[0142] In addition, it should be noted that although the third hole V3 in this embodiment is, for example, a through hole that penetrates the support piece 200, in some embodiments, the third hole V3 may also be a recess formed on the front or rear surface of the support piece 200 without penetrating the support piece 200.

[0143] As described above, compared to the other second portion 2332, the other first portion 2331 extends further away along a direction away from the virtual line L3. In the first direction N1, the width (not shown) of the third hole V3 corresponding to the other first portion 2331 may be greater than the width of the other second portion 2332. The definition of the width (not shown) of the third hole V3 corresponding to the other first portion 2331 being greater than the width of the other second portion 2332 is as described above.

[0144] In some embodiments, the second portion 2332 extends further away from the virtual line L2 than the third portion 2333. In the first direction N1, the width (not shown) of the second portion 2332 may be greater than the width (not shown) of the third portion 2333. The width (not shown) of the third portion 2333 is, for example, measured in the first direction N1 at the boundary between the second portion 2332 and the third portion 2333.

[0145] In some embodiments, the edge 2333A of another third portion 2333 may extend, for example, generally along the second direction N2, and the edge 2332A of another second portion 2332 may extend, for example, generally along a direction different from the first direction N1 and the second direction N2. In some embodiments, the included angle between the edges 2332A of another first portion 2331 and another second portion 2332 may be between 60 degrees and 120 degrees, but is not limited thereto.

[0146] In some embodiments, the edge 2332A of another second portion 2332 and / or the edge 2331A of another first portion 2331 may have an arc edge or other suitable shape. In some embodiments, the shapes of the first hole V1, the second hole V2, the third hole V3, and the fourth hole V4 are not limited to circular, and different shapes can be designed according to requirements.

[0147] By configuring the first hole V1, the second hole V2, the third hole V3, and the fourth hole V4, the design of the opening 211 of the foldable area 210 can be reduced due to the support piece 200 breaking from the outside to the inside during manufacturing. The first hole V1, the second hole V2, the third hole V3, and the fourth hole V4 can, for example, improve the crack stop effect, thereby improving the yield and reliability of the support piece 200 and the electronic device E, but the advantages are not limited to this. In addition, the configuration of the first hole V1, the second hole V2, the third hole V3 and the fourth hole V4 can be used for quality control calibration of the support plate 200, for example. By observing the relative relationship between the first hole V1, the second hole V2, the third hole V3 and / or the fourth hole V4, such as the distance between these holes, the relative area surrounded by these holes, or the relative relationship between the lines connecting these holes and other components, it can be determined whether the support plate 200 is deformed, thereby controlling the quality of the support plate 200.

[0148] like Figure 2 As shown, the first hole V1, the second hole V2, the third hole V3, and the fourth hole V4 define a region R. The area of ​​this region R can be larger than the area of ​​the foldable portion 210, and region R can substantially cover the foldable portion 210. Region R is the area defined by the line connecting the centers of the first hole V1, the second hole V2, the third hole V3, and the fourth hole V4. Furthermore, as mentioned above, in some embodiments, the foldable portion 210 has a plurality of openings 211 arranged sequentially, and a region 211A can be substantially defined by these openings 211. This region 211A is, for example, a rectangular region covering all the openings 211. This region 211A may, for example, have a first side 211E1 and a second side 211E2 opposite to each other, and the extending direction of the first side 211E1 and / or the second side 211E2 is, for example, parallel to a first direction N1. In addition, the first side 211E1 and the second side 211E2 can respectively obtain virtual extension lines VA and virtual extension lines VB, and the portion of the support piece 200 between the range of virtual extension lines VA and virtual extension lines VB is defined as the foldable area 210.

[0149] In some embodiments, the ratio of the area of ​​region R to the area of ​​the foldable portion 210 may be greater than 1 and less than or equal to 5 (1 < area of ​​region R / area of ​​foldable portion 210 ≤ 5), but is not limited thereto. In some embodiments, the ratio of the area of ​​region R to the area of ​​the foldable portion 210 may be greater than 1.5 and less than or equal to 4.5 (1.5 < area of ​​region R / area of ​​foldable portion 210 ≤ 4.5). In some embodiments, the ratio of the area of ​​region R to the area of ​​the foldable portion 210 may be greater than 2 and less than or equal to 3 (2 < area of ​​region R / area of ​​foldable portion 210 ≤ 3).

[0150] Please see Figure 1and Figure 5 The heat sink 300 can be disposed below the support plate 200 to improve the heat dissipation efficiency of the electronic device E. The heat sink 300 may include a metal sheet 310 and / or a graphite sheet 320, but is not limited thereto. The metal sheet 310 may include copper, aluminum, silver, other suitable materials, or combinations thereof, but is not limited thereto. The metal sheet 310 may, for example, be in contact with the support plate 200, and the graphite sheet 320 may, for example, be attached to the metal sheet 310, but is not limited thereto. The heat generated during the operation of the panel 100 can be conducted to the heat sink 300 via the support plate 200, thereby improving the heat dissipation efficiency.

[0151] like Figure 5 As shown, a notch 330 (e.g., a notch with an arc edge, but not limited thereto) may be formed on the heat sink 300 near the first hole V1 and / or the second hole V2. In other words, the notch 330 may be provided, for example, corresponding to the first hole V1 and / or the second hole V2. In other embodiments (not shown), similarly, a notch 330 (e.g., a notch with an arc edge, but not limited thereto) may be formed on the heat sink 300 near the third hole V3 and / or the fourth hole V4. In other words, the notch 330 may be provided, for example, corresponding to the third hole V3 and / or the fourth hole V4. A distance D6 may be provided between the heat sink 300 and the first hole V1 (or the second hole V2), the distance D6 being, for example, the shortest distance between the heat sink 300 and the first hole V1 (or the second hole V2). In some embodiments, the distance D6 may be, for example, greater than or equal to 0.2 mm or less than or equal to 6 mm, but not limited thereto. In some embodiments, the distance D6 may be, for example, greater than or equal to 0.5 mm or less than or equal to 4 mm, but not limited thereto. In some embodiments, the first hole V1, the second hole V2, the third hole V3, and the fourth hole V4 can also be used to position the heat sink 300 so that it is located in a preset position relative to the support plate 200, but are not limited thereto.

[0152] In some embodiments, the first portion 2221, another first portion 2231, first portion 2321, and another first portion 2331 of the support piece 200 are, for example, adjacent to or adjacent to the foldable portion 210, but are not limited thereto. In some embodiments (not shown), other portions of the support piece 200 may be selectively inserted between the first portion 2221, another first portion 2231, first portion 2321, and another first portion 2331 of the support piece 200 and the foldable portion 210, for example.

[0153] For example, such as Figure 6As shown, a fourth portion 2224 may be included between the first portion 2221 and the foldable portion 210. In the first direction N1, the first portion 2221 protrudes further than the fourth portion 2224. In some embodiments, in the second direction N2 (generally perpendicular to the first direction N1), the distance DA between the first hole V1 and the fourth portion 2224 may be less than the distance DB between the first hole V1 and the second portion 2222. Distance DA can be defined as the shortest distance between the center of the first hole V1 and the fourth portion 2224 in the second direction N2. Distance DB can be defined as the shortest distance between the first hole V1 and the second portion 2222 in the second direction N2. In some embodiments, the distance D5 between the first hole V1 and the foldable portion 210 may be, for example, between 1 mm and 5 mm (1 mm ≤ distance D5 ≤ 5 mm), but is not limited thereto. In some embodiments, distance D5 may be between 1.5 mm and 4.5 mm (1.5 mm ≤ distance D5 ≤ 4.5 mm). In some embodiments, the distance D5 may be between 2 mm and 4 mm (2 mm ≤ distance D5 ≤ 4 mm). When the distance D5 > 5 mm, the fixing mechanism F (see reference) Figure 8 The fixing effect is not good. When the distance D5 < 1 mm, the first hole V1 may be too close to the area of ​​the foldable part 210, which may affect the patterning of the opening 211 of the foldable part 210, or the setting may affect the subsequent folding effect.

[0154] In some embodiments, the ratio of distance D5 to the width D1 of the first hole V1 may be between 5 and 30 (5 ≤ distance D5 / width D1 ≤ 30), but is not limited thereto. In some embodiments, the ratio of distance D5 to the width D1 of the first hole V1 may be between 10 and 25 (10 ≤ distance D5 / width D1 ≤ 25). In some embodiments, the ratio of distance D5 to the width D1 of the first hole V1 may be between 15 and 30 (15 ≤ distance D5 / width D1 ≤ 30). Similarly, a fourth portion (not shown) may also be formed between another first portion 2231, first portion 2321, or another first portion 2331 and the foldable portion 210, and therefore will not be described further here.

[0155] Please refer to Figure 6In some embodiments, the distance D4 between the first hole V1 (e.g., the center of the first hole V1) and the second hole V2 (e.g., the center of the second hole V2) in the second direction N2 can be between 5 mm and 30 mm (5 mm ≤ distance D4 ≤ 30 mm), but is not limited thereto. In some embodiments, the distance D4 in the second direction N2 can be between 8 mm and 27 mm (8 mm ≤ distance D4 ≤ 27 mm), but is not limited thereto. In some embodiments, the distance D4 can be between 10 mm and 20 mm (10 mm ≤ distance D4 ≤ 20 mm). If the distance D4 is less than 5 mm, it will restrict the space of the foldable portion 210, affecting the foldability of the electronic device E. If the distance D4 is greater than 30 mm, it will be detrimental to the fixing effect of the first hole V1 and the second hole V2 in the manufacturing process. Similarly, in the second direction N2, the distance (not shown) between the third hole V3 (e.g., the center of the third hole V3) and the fourth hole V4 (e.g., the center of the fourth hole V4) may be between 5 mm and 30 mm (5 mm ≤ distance ≤ 30 mm). In some embodiments, the distance (not shown) between the third hole V3 and the fourth hole V4 may be the same as or different from the distance D4 between the first hole V1 and the second hole V2.

[0156] The shapes of the edges of the aforementioned first, second, third, and / or fourth parts can also be adjusted according to the user's needs. For example... Figure 7 As shown, the edge 2222A of the second part 2222 is not inclined relative to the edge 2223A of the third part 2223 and has an irregular shape. The edge 2222A of the second part 2222 is formed, for example, by straight edges and curved edges, but is not limited thereto.

[0157] Please see Figure 8 When it is desired to use a laser or cutting tool to process the support plate 200 to form the opening 211 on the foldable portion 210, a fixing mechanism F can be provided, for example, in the first hole V1, the second hole V2, the third hole V3, and / or the fourth hole V4 of the support plate 200, but is not limited thereto. In this way, the support plate 200 can be securely fixed to the platform, for example, reducing the impact of the displacement of the support plate 200 on the formation of the opening 211, but the design advantages of the first hole V1, the second hole V2, the third hole V3, and / or the fourth hole V4 are not limited thereto. In some embodiments, the depth T of the first hole V1, the second hole V2, the third hole V3 and / or the fourth hole V4 in the normal direction Z of the support sheet 200 is, for example, greater than or equal to 0.05 mm and less than or equal to 0.3 mm (0.05 mm ≤ thickness T ≤ 0.3 mm), but is not limited thereto. When the depth T is designed as above, the fixing mechanism F can be reduced from disengaging from the first hole V1, the second hole V2, the third hole V3 and / or the fourth hole V4 during processing, and the thinness of the electronic device E can be ensured.

[0158] During the assembly of electronic device E, a mechanism can be installed in the first hole V1, the second hole V2, the third hole V3 and / or the fourth hole V4 to fix the support piece 200. This mechanism can also hold each component (or layer) in place, reducing the positional shift between components (or layers) during assembly, thereby improving the assembly quality of electronic device E.

[0159] Please see Figure 9 In some embodiments, the cross-sectional structure of the first hole V1, the second hole V2, the third hole V3, and the fourth hole V4 can be, for example, trapezoidal in shape, but is not limited thereto. For example, the first hole V1, the second hole V2, the third hole V3, or the fourth hole V4 may have different widths (diameters) at the end adjacent to the heat sink 300 and at the end adjacent to the panel 100. Specifically, the first hole V1, the second hole V2, the third hole V3, and / or the fourth hole V4 may have a width D1 at the end adjacent to the heat sink 300, and the first hole V1, the second hole V2, the third hole V3, and / or the fourth hole V4 may have a width D3 at the end adjacent to the panel 100, wherein... Figure 9 The width D1 can be equivalent to Figure 2 The width D1 in the text.

[0160] In some embodiments, the ratio of width D1 to width D3 may be greater than 1 and less than or equal to 2 (1 < width D1 / width D3 ≤ 2), but is not limited thereto. Through the above design, since the panel 100 can be fixed to the support piece 200, for example, via an attachment (not shown), when the end of these holes adjacent to the panel 100 has a smaller width D3, the fixing area of ​​the panel 100 to the support piece 200 can be increased, thereby improving the yield of the electronic device E.

[0161] The features of the aforementioned embodiments can be arbitrarily combined and used as long as they do not violate the spirit of the invention or conflict with each other.

[0162] In summary, this disclosure provides an electronic device including a panel and a support piece. The panel has a foldable region and a folding axis. The support piece is disposed below the panel and includes a foldable portion and a first non-foldable portion. The foldable portion overlaps with the foldable region, and the first non-foldable portion is connected to the foldable portion and includes a first part and a second part. The first part is located between the second part and the foldable portion, and the first part has a first hole, and in a first direction parallel to the folding axis, the first part protrudes more than the second part.
